Description

Connector components and hair care devices Technical Field

[0001] This disclosure relates to a connector assembly and a hair care device. Background Technology

[0002] As people's living standards improve, multi-functional styling tools (such as curling irons and straighteners) are becoming increasingly popular. These tools can dry hair or create simple curls and straighten styles, and are very convenient to use as handheld devices for blow-drying and styling.

[0003] A multi-functional styler can be used as both a hair dryer and a styler (e.g., for curling, straightening, etc.). Generally, a multi-functional styler provides airflow by extending a gas flow path through the device, which passes through a heating element to generate hot air at the outlet, thus enabling the styler to dry and style hair.

[0004] Existing multi-functional styling tools have a fixed overall shape and are mostly straight rod structures that cannot be bent, making them inconvenient to store and operate. Moreover, when users operate these multi-functional styling tools and style their hair, the hand grip is too high, the center of gravity is not ergonomic, and fatigue is easily felt after prolonged use.

[0005] Existing technologies include multi-functional shapers that achieve both upright and bent states through end-face rotation and bending. However, these multi-functional shapers have at least the following drawbacks: 1. The bent shape is relatively rigid, which is less acceptable to female users; 2. The bent shape creates a concave airflow channel, hindering air circulation and requiring a higher-power motor, thus increasing the cost of the multi-functional shaper; 3. The multi-functional shaper is noisy, and considering that it needs to be close to the user's ear during use, the user experience is poor; 4. Rotating the end face 180 degrees will cause internal wiring to twist, reducing the lifespan of the wiring harness. Summary of the Invention

[0042] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the disclosure. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present disclosure are shown in the accompanying drawings.

[0043] It should be noted that, where there is no conflict, the embodiments and features described in this disclosure can be combined with each other. The technical solutions of this disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0044] Figure 1 is a structural schematic diagram of a hair care device in a longitudinally rotated state according to one embodiment of the present disclosure. Figure 2 is a structural schematic diagram of a hair care device in a longitudinally rotated state according to one embodiment of the present disclosure from another angle. Figure 3 is a structural schematic diagram of a hair care device in a relatively bent state according to one embodiment of the present disclosure. Figure 4 is a structural schematic diagram of a hair care device in a relatively bent state according to one embodiment of the present disclosure from another angle. Figure 5 is a partial structural schematic diagram of a hair care device according to one embodiment of the present disclosure.

[0045] As shown in Figures 1 to 5, 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, 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, flow through the handle portion 100, the connector assembly 300, and the main body portion 200, and then exit 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.

[0046] 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.

[0047] As shown in Figure 5, the hair care device 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] In this disclosure, a printed circuit board (not shown) is located within the handle portion 100 and positioned closer to the connector assembly 300 than the motor 600 and fan; thereby, the gas drawn in by the motor 600 and fan can flow through the printed circuit board, thereby cooling the electronic components on the printed circuit board and improving the service life of the printed circuit board.

[0052] A user interaction device 700 is disposed on the handle portion 100. In one specific embodiment, the user interaction device 700 may be a button, which the user activates to operate the hair care appliance. In this disclosure, the projection of the user interaction device 700 (projection on the plane containing the longitudinal axis) does not coincide with the projection of the motor 600 (projection on the plane containing the longitudinal axis). Therefore, the user does not directly hold the area where the motor is located, reducing the impact of vibration generated by the motor on the user and improving the user experience.

[0053] The handle portion 100 has a through hole, which forms the gas inlet of the handle portion 100. The gas inlet of the handle portion 100 does not intersect with the user interaction device 700. Therefore, when the user holds the handle portion 100, the user's hand will not cover these through holes, thus not affecting the gas entering the handle portion 100.

[0054] In a preferred embodiment, the length of the main body 200 is approximately 1 / 4 of the total length of the hair care device; that is, the main body 200 of this disclosure has a shorter size, which makes it easier for the user to hold the hair care device and improves the user experience.

[0055] In this disclosure, as shown in Figures 1 to 4, the handle portion 100 and the main body portion 200 are pivotally coupled to each other via a connector assembly 300, such that the main body portion 200 and the handle portion 100 are aligned longitudinally or bent relative to each other. Specifically, as shown in Figures 1 and 2, when the handle portion 100 and the main body portion 200 are in a longitudinally aligned state, the central axis of the handle portion 100 is set approximately vertically, and the central axis of the main body portion 200 is set approximately coincidentally with the central axis of the handle portion 100. As shown in Figures 3 and 4, when the handle portion 100 and the main body portion 200 are in a relatively bent state, an 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 a specific embodiment, this first angle can be greater than or equal to 85° and less than or equal to 180°.

[0056] The handle portion 100 and the main body portion 200 have a gas flow path extending through the handle portion 100 and the main body portion 200 from the gas inlet in the handle portion 100 to the gas outlet in the main body portion 200; when the gas flows along the gas flow path, the gas flows sequentially through the handle portion 100, the connector assembly 300 and the main body portion 200, and is discharged from the gas outlet at the free end of the main body portion 200.

[0057] The structure of the connector assembly 300 will be described in detail below with reference to the accompanying drawings.

[0058] Figure 6 is a structural schematic diagram of the connector assembly of a hair care device according to an embodiment of the present disclosure. Figures 7 to 9 are structural schematic diagrams of the connector assembly of a hair care device according to an embodiment of the present disclosure from different angles. Figure 10 is a structural schematic diagram of the main body connector 320 of a hair care device according to an embodiment of the present disclosure. Figure 11 is a structural schematic diagram of the handle connector 310 of a hair care device according to an embodiment of the present disclosure.

[0059] As shown in Figures 6 to 11, the connector assembly 300 of this disclosure may include components such as a handle connector 310, a main connector 320, and a flow guide 330.

[0060] The handle connector 310 and the main body connector 320 can cooperate with each other and are pivotally connected. That is, the handle connector 310 and the main body connector 320 of this disclosure can be rotatably fixed to each other, so that the main body 200 can maintain a fixed posture relative to the handle 100 at a first angle.

[0061] The handle connector 310 maintains gas communication with the handle portion 100, and the main body connector 320 maintains gas communication with the main body portion 200. Thus, the handle portion 100, the connector assembly 300, and the main body portion 200 can jointly form a gas flow path. In other words, the handle connector 310 of this disclosure can be fixed to the handle portion 100, and the main body connector 320 can be fixed to the main body portion 200. Therefore, based on the pivotal connection between the handle connector 310 and the main body connector 320, the main body portion 200 can rotate relative to the handle portion 100.

[0062] In this disclosure, regardless of whether the handle portion 100 and the main body portion 200 are in a longitudinally aligned state or a relatively bent state, the gas flow path can always be sealed within the handle portion 100, the connector assembly 300, and the main body portion 200. That is, gas will not leak from the gas inlet of the handle portion 100 to the gas outlet of the main body portion 200.

[0063] Furthermore, the connector assembly 300 of this disclosure has a lateral width, wherein the lateral direction is the direction of the pivot axis of the connector assembly 300, and the lateral width is the dimension of the connector assembly 300 in the direction of the pivot axis. Preferably, the lateral width is less than or equal to the outer diameter of the handle portion 100 or the main body portion 200, thereby the connector assembly 300 of this disclosure does not occupy additional storage space and makes hair care appliances easier to store.

[0064] The air guide 330 is configured to maintain a constant position relative to the handle portion 100 during longitudinal alignment and relative bending; thereby, the air guide 330 can guide the gas in the gas flow path so that the gas does not generate turbulence or generates as little turbulence as possible in the gas flow path, thereby making the hair care device of this disclosure have less airflow loss.

[0065] In a preferred embodiment, a flow deflector 330 is formed within the handle connector 310; in this disclosure, the flow deflector 330 is configured to guide gas flow through the heater 400; that is, the flow deflector 330 is located upstream of the heater 400 along the gas flow direction within the gas flow path.

[0066] In order to achieve efficient gas flow guidance within the gas flow path, the guide 330 of this disclosure extends in a direction inclined to the longitudinal axis; specifically, the guide 330 of this disclosure is inclined to the longitudinal axis along the gas flow direction in the gas flow path; in other words, the guide 330 of this disclosure is inclined to the longitudinal axis along the direction from upstream to downstream of the gas in the gas flow path.

[0067] In this disclosure, the flow guide 330 is configured to guide gas through at least one side of the gas outlet of the handle portion 100 into the gas inlet of the main body portion 200. More preferably, there are two flow guides 330, which are configured to guide gas through both sides of the gas outlet of the handle portion 100 into the gas inlet of the main body portion 200.

[0068] Figure 12 is a cross-sectional structural schematic diagram (longitudinal alignment state) of the connector assembly of a hair care device according to an embodiment of the present disclosure. Figure 13 is a structural schematic diagram of the sealing cover 340 of a hair care device according to an embodiment of the present disclosure. Figure 14 is a cross-sectional structural schematic diagram (relatively bent state) of the connector assembly of a hair care device according to an embodiment of the present disclosure. Figures 15 and 16 are structural schematic diagrams of the handle connector of a hair care device according to an embodiment of the present disclosure at different angles.

[0069] As shown in Figures 6 to 16, 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.

[0070] 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.

[0071] As shown in Figures 15 and 16, 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.

[0072] 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.

[0073] The flow guide 330 is located within the first ring component 311B. Specifically, there can be two flow guides 330: one flow guide 330 located within the first ring component 311B and the other flow guide 330 located within the second ring component 312B, thereby enabling the flow guides to direct the gas within the first ring component 311B and the second ring component 312B. In a specific embodiment, the flow guide can be integrally formed with the first connector component 311, and the flow guide can also be integrally formed with the second connector component 312.

[0074] As shown in Figure 12, the flow guide 330 of this disclosure includes a flow guide plate with a curved surface. The curved surface includes an outer side and an inner side relative to the longitudinal axis of the handle portion 100. During gas flow, gas is introduced from at least one side of the gas outlet of the handle portion 100 to the gas inlet of the main body portion 200 via the outer side and / or the inner side. In a preferred embodiment, the notch of the curved surface of the flow guide plate faces the longitudinal axis, thereby allowing gas to flow through the surface of the curved surface and be effectively guided.

[0075] Referring again to Figure 2, the first ring component 311B of this disclosure includes a first end in the axial direction and a second end corresponding to the first end; wherein, the first end of the first ring component 311B forms a first annular protrusion 311D, the size (e.g., outer diameter) of the first annular protrusion 311D is smaller than the size (e.g., outer diameter) of the first ring component 311B, and the first annular protrusion 311D and the first ring component 311B have the same central axis, which is the aforementioned pivot axis. In a preferred embodiment, a first limiting component 311E is provided on the outer peripheral surface of the first annular protrusion 311D, the first limiting component 311E can be a protrusion, and the first limiting component 311E can be provided in two forms, which can be evenly distributed along the outer peripheral surface of the first annular protrusion 311D. Of course, the number of the first limiting components 311E can also be set to other values.

[0076] Similarly, the second ring component 312B of this disclosure includes a first end in the axial direction and a second end corresponding to the first end; wherein, the first end of the second ring component 312B forms a second annular protrusion 312D, the size (e.g., outer diameter) of the second annular protrusion 312D is smaller than the size (e.g., outer diameter) of the second ring component 312B, and the second annular protrusion 312D and the second ring component 312B have the same central axis, which is the aforementioned pivot axis. In a preferred embodiment, a second limiting component 312E is provided on the outer peripheral surface of the second annular protrusion 312D, the second limiting component 312E can be a protrusion, and the second limiting component 312E can be provided in two, and the two second limiting components 312E can be evenly distributed along the outer peripheral surface of the second annular protrusion 312D. Of course, the number of the second limiting components 312E can also be set to other values.

[0077] In this disclosure, the connector assembly 300 includes a sealing cover 340 disposed on the outer side of the first ring member 311B of the handle connector 310. In other words, the sealing cover 340 of this disclosure can be configured as two, with one sealing cover 340 disposed at the second end of the first ring member 311B and the other sealing cover 340 disposed at the second end of the second ring member 312B. Thus, through the arrangement of the sealing cover 340, gas will not leak outward from the handle connector 310.

[0078] Referring again to Figure 12, in this disclosure, a guide portion 341 is provided on the inner side of the sealing cover plate 340. The guide portion 341 is located close to the guide device 330, and the guide portion 341 cooperates with the guide device 330 to form a guide air duct toward the gas inlet of the main body 200.

[0079] Specifically, the flow guide 341 can be disposed within the handle connector 310, for example, the flow guide 341 can be disposed within the first ring member 311B of the handle connector 310. Furthermore, the flow guide surface of the flow guide 341 is inclined, so that the flow guide 341 has approximately the same spacing from the outer side of the flow guide 330.

[0080] In a preferred embodiment, the flow guide 330 is configured to be inclined in a direction close to the longitudinal axis from bottom to top (i.e., along the gas flow direction), and similarly, the flow guide surface of the flow guide 341 is also inclined in a direction close to the longitudinal axis from bottom to top (i.e., along the gas flow direction).

[0081] The main connector 320 of this disclosure can be integrally molded. For example, the main connector 320 can be integrally injection molded from plastic material. Meanwhile, as shown in FIG10, the main connector 320 of this disclosure may include a main body base 321 and a main body ring component 322; wherein, the main body base 321 can form a gas outlet of the connector assembly 300, and the gas outlet of the connector assembly 300 can be connected and communicated with the gas inlet of the main body 200, so that the gas flowing inside the connector assembly 300 can enter the main body 200. That is to say, the main connector 320 of this disclosure can be fixed to the main body 200.

[0082] In this 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 to the main ring component 322.

[0083] Specifically, referring to Figure 10, the main ring component 322 of this 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. A limiting structure 322A is provided 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 evenly distributed along the circumference of the inner flange.

[0084] When the handle connector 310 and the main body connector 320 are assembled together, the first annular protrusion 311D is rotatably disposed in the inner flange of the first end of the main body ring component 322; similarly, the second annular protrusion 312D is rotatably disposed in the inner flange of the second end of the main body ring component 322; and both the first limiting component 311E and the second limiting component 312E can cooperate with the limiting groove, so that the handle connector 310 and the main body connector 320 maintain a fixed posture at a first angle.

[0085] Based on the above structure, the rotatable fixing of the handle connector 310 and the main body connector 320 in this disclosure means that when the first limiting member 311E and / or the second limiting member 312E are located in the limiting groove, the handle connector 310 and the main body connector 320 maintain a fixed posture at a first angle; in addition, when the handle connector 310 is kept fixed and a force is applied to the main body connector 320, and the force is greater than a preset value to dislodge the first limiting member 311E and / or the second limiting member 312E from the limiting groove, the handle connector 310 and the main body connector 320 can rotate relative to each other until the first limiting member 311E and / or the second limiting member 312E re-enter the limiting groove, at which point the handle connector 310 and the main body connector 320 can be fixed to each other.

[0086] In this disclosure, the number of limiting grooves is not limited to this; it can also be set to 6 or 8, etc. Thus, when the hair care device of this disclosure is in use, the main body 200 can be held in multiple positions relative to the handle 100, thereby facilitating the user's use.

[0087] The connecting component 313 of this disclosure is arranged in a direction parallel to the pivot axis of the connector assembly 300. Therefore, the first connector component 311 and the second connector component 312 of this disclosure can be easily inserted, facilitating the assembly of hair care appliances.

[0088] Referring again to Figures 1 and 4, in this disclosure, when the first angle is 0°, there is a first cross-section 350 between the outer surfaces of the main body connector 320 and the handle connector 310; when the first angle is 90°, there is a second cross-section 360 between the outer surfaces of the main body connector 320 and the handle connector 310. The maximum depth of the first cross-section 350 is greater than or equal to the maximum depth of the second cross-section 360. As a result, the hair care device of this disclosure can be easily bent and kept in a bent state; moreover, the hair care device has a more aesthetically pleasing shape after bending.

[0089] The disclosed hair care appliance can operate in both upright and bent positions to achieve multi-angle use. When using the hair care appliance to blow-dry hair, the main body 200 can be bent relative to the handle 100 at a 90° angle or other suitable angle. When using the hair care appliance to curl hair, the main body 200 and handle 100 can be placed in a coaxial upright position for easy curling. Of course, users can use the hair care appliance in the upright position to blow-dry hair or in the bent position to curl hair, as long as the user finds the angle comfortable.

[0090] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
