Description

Technical Field

[0001] This utility model relates to the field of hair dryer technology, and in particular to a hair dryer device with adjustable air outlet direction. Background Technology

[0002] As a basic hair styling tool, the core function of a hair dryer is to dry and style hair through the combination of high-speed airflow and heat. In the hair styling industry, especially in the curling styling market, traditional hair dryers generally adopt an axial airflow design, meaning that the central axis of the nozzle is completely parallel to the airflow direction. While this linear airflow pattern can meet basic hair drying needs, it has significant technical drawbacks when styling curls: First, parallel airflow cannot generate effective rotational torque, making it difficult for hair to form a lasting curl; second, users must use additional tools such as curling irons and curling combs to physically curl the hair, requiring frequent switching of tools during the hot air styling process, significantly increasing the complexity of the operation.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0042] The following is in conjunction with the appendix Figures 1 to 9 The technical solution of this utility model will be further illustrated through specific implementation methods.

[0043] A blower with adjustable air outlet direction includes a blower body 10 and a handle 20. One end of the handle 20 is connected to the blower body 10. The blower body 10 includes a shell 1, an air guide 2, an adjustment component 3, a fan 4, and a heating component 5. The air guide 2, the adjustment component 3, the fan 4, and the heating component 5 are disposed inside the shell 1.

[0044] The outer casing 1 is cylindrical, the fan 4 is located at the rear of the outer casing 1, the heating element 5, the air duct 2 and the adjusting element 3 are located at the front of the outer casing 1, the air duct 2 is sleeved on the outside of the heating element 5, and the adjusting element 3 is sleeved on the outside of the air duct 2.

[0045] The outer casing 1 is provided with a front air outlet 101 and several sets of side air outlets 102. The front air outlet 101 is located at the front end of the outer casing 1, and the several sets of side air outlets 102 are spaced apart on the side wall of the outer casing 1. The air guide duct 2 is fixedly arranged relative to the outer casing 1. The air guide duct 2 is provided with several air guide ports 21. The several air guide ports 21 are spaced apart on the side wall of the air guide duct 2, and the several side air outlets 102 are correspondingly arranged with the several air guide ports 21.

[0046] The adjusting component 3 is tubular and is rotatably disposed between the outer shell 1 and the air guide duct 2. The adjusting component 3 is provided with a front air outlet 31 and several side air outlets 32. The front air outlet 31 is located at the front end of the adjusting component 3, and several side air outlets 32 are spaced apart on the side wall of the adjusting component 3.

[0047] When the front air outlet 31 is rotated to a position corresponding to the front air outlet 101, the side air outlet 32 ​​does not correspond to the side air outlet 102; when the side air outlet 32 ​​is rotated to a position corresponding to the side air outlet 102, the front air outlet 31 does not correspond to the front air outlet 101; by rotating the control adjustment component 3, the air outlet of the blower can be switched between the front air outlet 101 and the side air outlet 102.

[0048] The outer casing 1 serves as a supporting structure, housing core components such as the fan 4 and the heating element 5. Its cylindrical shape guides the linear flow of air. The air duct 2 establishes the basic airflow path, and its fixed installation ensures that the heat from the heating element 5 is evenly distributed to the airflow. The adjusting component 3 changes the airflow path by rotation; its tubular shape forms a clearance fit with the air duct 2, ensuring a tight seal during rotation. The side air outlets 102 on the outer casing 1 and the air guides 21 on the air guide duct 2 are all configured in a one-to-one correspondence. The correspondence between the side air outlets 32 of the adjustment component 3 and the air guides 21 is achieved by angle matching. For example, the air guides 21 (side air outlets 102) can be evenly distributed along the circumference and extend along the axial direction. The distribution of the side air outlets 32 is consistent with the distribution of the air guides 21. When the adjustment component 3 is rotated to the point where one side air outlet 32 ​​corresponds to one air guide 21 (side air outlet 102), then all other side air outlets 32 correspond one-to-one with other air guides 21 (side air outlets 102).

[0049] Specifically, the fan 4 drives airflow into the outer casing 1, and the airflow passes forward through the heating element 5 to form hot air. When the adjusting component 3 rotates to align the front air outlet 31 with the front air outlet 101 of the outer casing 1, the side air outlet 32 ​​is not aligned with the air guide 21 (side air outlet 102), and the side air outlet 32 ​​overlaps with the solid part of the side wall of the outer casing 1. This is equivalent to the side air outlet 102 being in a closed state, and the airflow is blocked. At this time, hot air can only be blown out from the front air outlet 101. When the adjusting component 3 rotates to align the side air outlet 32 ​​with the air guide 21 (side air outlet 102), the airflow passes through the air guide 21 and the side air outlet 32 ​​and is blown out from the side air outlet 102, forming a flow around the outer casing under the action of multiple sets of side air outlets 102 of the outer casing 1. The gap between the air guide pipe and the adjusting component can be controlled within 1-3 mm, which avoids airflow leakage and allows the component to rotate freely. The flat plate portion of the housing sidewall provides a flat surface, facilitating the machining of the side air outlets and the directional discharge of airflow.

[0050] Traditional blower devices only have a single axial air outlet function and cannot generate directional airflow. This invention achieves dynamic switching of airflow path through a nested tubular structure. The blower body adopts a layered layout with an outer shell 1 enclosing an air guide duct 2 and an adjustment component 3. The air guide duct 2 is fixed to the outside of the heating element 5 to form a basic air duct, while the adjustment component 3 forms a rotatable adjustment component between the outer shell 1 and the air guide duct 2. When the adjustment component 3 rotates, the side air outlet 32 ​​corresponds to the side air outlet 102 of the outer shell 1, and the airflow is blown out from the side air outlet 102 to form a surrounding airflow. When the front air outlet 31 of the adjustment component 3 is aligned with the front air outlet 101 of the outer shell, the side air outlet 32 ​​is misaligned with the side wall of the outer shell 1, and the airflow is concentrated and output from the front air outlet 101. By rotating and adjusting, the airflow output direction is changed, which retains the traditional axial air outlet function and can generate a circumferential airflow through multiple sets of side air outlets, thereby solving the technical defects of the single air outlet mode. Users can adjust the axial direct airflow or circumferential rotating airflow of the blower according to their styling needs, eliminating the need for additional tools.

[0051] Furthermore, the side air outlet 102 includes a forward air outlet 1021 and a reverse air outlet 1022, with each set of forward air outlets 1021 and reverse air outlets 1022 arranged side by side;

[0052] When the side air outlet 32 ​​is directly facing the forward air outlet 1021, the airflow blown out from the side air outlet 102 surrounds the outer shell 1 clockwise.

[0053] When the side air outlet 32 ​​is directly facing the reverse air outlet 1022, the airflow blown out from the side air outlet 102 surrounds the outer shell 1 counterclockwise.

[0054] When the side air outlet 32 ​​is directly opposite the side wall of the outer casing 1, airflow is blown out from the front air outlet 101.

[0055] Vector control of the blowing direction is achieved by setting a dual-mode side air outlet 102 structure. Specifically, the left and right side-by-side forward air outlets 1021 and reverse air outlets 1022 constitute a direction control unit, and different air outlet combinations can be selected by rotating and positioning the adjustment component 3. When the adjustment component 3 aligns the side air outlet 32 ​​with the forward air outlet 1021, the specially designed forward air guiding structure causes the airflow to generate a clockwise tangential component, forming a spiral airflow field around the air duct. This airflow pattern can help the hair curl naturally. The mirrored layout of the reverse air outlet 1022 allows for counterclockwise rotating airflow, providing a choice for different curling direction requirements.

[0056] In some embodiments, the air inlets 21 of the air duct 2 are two parallel air slots extending along the axial direction of the air duct 2. The two air slots are respectively provided for the forward air outlet 1021 and the reverse air outlet 1022, so that the airflow is more concentrated.

[0057] Furthermore, the forward air outlet 1021 includes a forward air outlet groove 10211 and a forward air guide plate 10212. The forward air outlet groove 10211 extends along the axial direction of the outer casing 1. The right side of the forward air guide plate 10212 is connected to the right side of the forward air outlet groove 10211, and the left side of the forward air guide plate 10212 extends downward toward the left side of the forward air outlet groove 10211.

[0058] The reverse air outlet 1022 includes a reverse air outlet groove 10221 and a reverse air guide plate 10222. The reverse air outlet groove 10221 extends along the axial direction of the outer shell 1. The left side of the reverse air guide plate 10222 is connected to the left side of the reverse air outlet groove 10221, and the right side of the reverse air guide plate 10222 extends downward toward the right side of the reverse air outlet groove 10221.

[0059] The forward air outlet slot 10211 and the reverse air outlet slot 10221 are respectively arranged on the left and right sides.

[0060] The forward air outlet slot 10211 refers to a through-hole opened along the length of the outer shell 1. It can be implemented using a straight slot structure formed by stamping or injection molding. Its axial extension characteristics ensure both the opening size of the forward air outlet 1021 and the stable delivery of airflow along a predetermined trajectory. The forward air guide plate 10212 refers to a guide component fixed to the right side of the forward air outlet slot 10211. It can be formed by stamping and bending a thin stainless steel sheet. Its downward-sloping design on the left side causes the airflow to deflect clockwise after contacting the plate surface. The reverse air guide plate 10222 refers to a guide component fixed to the left side of the reverse air outlet slot 10221. It can be integrally formed using an injection molded part of the same material as the outer shell 1. Its downward-sloping shape on the right side forces the airflow to move counterclockwise. Each set of side air outlets 102 has forward and reverse air outlets arranged in a left-right distribution, and the air guide plates do not interfere with each other, so that each side air outlet 32 ​​of the adjustment component can correspond to the side air outlet 102 in the same direction, so that the airflow direction blown out from the side air outlet 102 is uniform.

[0061] Specifically, when the adjusting component 3 is rotated so that the side air outlet 32 ​​is aligned with the forward air outlet 1021, the airflow enters the forward air outlet slot 10211 through the air guide 21 and rises to the right along the surface of the forward air guide plate 10212, causing the airflow to generate a clockwise tangential velocity component along the surface of the forward air guide plate 10212 and the outer surface of the outer shell 1; at the same time, the reverse air outlet slot 10221 is in a closed state to prevent airflow diversion. When the adjusting component 3 is switched to the reverse air outlet 1022, the reverse air outlet slot 10221 rises to the left along the surface of the reverse air guide plate 10222, causing the airflow to generate a counterclockwise tangential velocity component along the surface of the reverse air guide plate 10222 and the outer surface of the outer shell 1, forming a counterclockwise circulation. The left-right distribution design of the forward and reverse air outlets ensures that the adjusting component 3 can only open the air outlet channel in one direction at a time, ensuring that the airflow circulation direction is controllable.

[0062] Furthermore, it also includes an adjustment operating component 6, which includes an operating part 61 and a mounting part 62. The operating part 61 is located outside the housing 1, and the mounting part 62 passes through the housing 1 and is installed and connected to the adjustment assembly 3. The adjustment operating component 6 controls the rotation of the adjustment assembly 3 relative to the housing 1.

[0063] The operating part 61 refers to the component located outside the blower for user operation; the mounting part 62 refers to the transmission component connecting the external operating part 61 and the internal adjustment component 3. By setting the adjustment operating part 6 with an internal and external linkage structure, the mode switching between the front air outlet 101 and the side air outlet 102 can be completed by a single action (tossing or rotating).

[0064] Specifically, when the user controls the operating unit 61, the mounting unit 62 drives the adjusting component 3 to rotate between the housing 1 and the air duct 2. The user controls the operation unit 61, located outside the housing 1, to move (slide or rotate), and this movement is precisely transmitted to the adjusting component 3 via the mounting unit 62, causing a relative positional change between the side air outlet 32 ​​of the adjusting component 3 and the side air outlet 102 of the housing. When the adjusting component 3 rotates until the side air outlet 32 ​​is fully aligned with the side air outlet 102, airflow is output through the side air outlet 102; when the adjusting component 3 rotates until the front air outlet 31 is aligned with the front air outlet 101, airflow switches to output through the front air outlet 101. The mounting unit 62 forms a physical barrier through the structure of the housing 1, ensuring both accessibility for external operation and maintaining the stability of the internal structure.

[0065] Furthermore, the adjustment operation member 6 is located at the front end of the housing 1, and the housing 1, the adjustment assembly 3, and the adjustment operation member 6 are coaxially arranged.

[0066] By arranging the adjustment operating component 6 at the front end of the housing 1 and maintaining the coaxial design of the housing 1, adjustment component 3, and adjustment operating component 6, a compact adjustment system is constructed. Positioning the adjustment operating component 6 at the front end of the housing 1 allows the operating part 61 to be close to the front of the air duct body, facilitating rotational control of the adjustment operating component 6 with the thumb or forefinger during single-handed operation. The coaxial arrangement of the housing 1, adjustment component 3, and adjustment operating component 6 ensures consistent transmission of rotational motion, eliminates mechanical friction or motion interference caused by misalignment, and ensures precise matching of the relative motion trajectory between the adjustment component 3 and the housing 1 during rotational adjustment.

[0067] Specifically, when the user rotates the operating part 61, the mounting part 62 rotates coaxially, causing the adjustment component 3 to rotate between the outer casing 1 and the air duct 2. The rotation angle of the operating part 61 is precisely transmitted to the adjustment component 3 through the mounting part 62, causing a relative positional change between the side air outlet 32 ​​of the adjustment component 3 and the side air outlet 102 of the outer casing.

[0068] This coaxial layout also optimizes the utilization of internal space, making the assembly relationship between the air duct structure and the adjustment mechanism more reasonable, and avoiding problems such as increased rotational resistance or wear of parts caused by structural misalignment.

[0069] Furthermore, the mounting part 62 includes a connecting shaft 621 and two protruding ribs 622. The protruding ribs 622 are located on the outside of the connecting shaft 621 and extend along the axial direction of the connecting shaft 621. The two protruding ribs 622 are symmetrically arranged.

[0070] The front end of the adjustment component 3 is provided with an installation sleeve 33. The opening of the installation sleeve 33 is provided with two slots 331. The slots 331 extend along the axial direction of the installation sleeve 33. The two slots 331 are symmetrically arranged. The rib 622 is connected to the slots 331.

[0071] The mechanical connection between the adjusting operating component 6 and the adjusting assembly 3 is achieved through the axial insertion of the connecting shaft 621 and the mounting sleeve 33. Two protruding ribs 622 are embedded in symmetrically arranged slots 331, forming a circumferential limiting structure. This allows the rotational torque of the adjusting operating component 6 to be directly transmitted to the adjusting assembly 3, preventing slippage or offset due to connection gaps or structural asymmetry. The design of the protruding ribs 622 extending axially along the connecting shaft 621 enhances the stability of axial positioning. The symmetrically distributed protruding ribs 622 and slots 331 distribute the force evenly in the circumferential direction, ensuring no relative displacement between the adjusting assembly 3 and the outer casing 1 during rotation. This plug-in mating structure not only simplifies the assembly process but also improves the accuracy of the adjustment angle through a physical limiting mechanism, making the air outlet switching operation more reliable.

[0072] Furthermore, the outer casing 1 includes a front end casing 11, which is provided with a front air outlet 101 and a shaft mounting hole 103. The shaft mounting hole 103 is provided with rib through holes 104 on both the left and right sides. The connecting shaft 621 is rotatably disposed in the shaft mounting hole 103. Two protruding ribs 622 are respectively provided corresponding to the rib through holes 104 on both sides, and the protruding ribs 622 are movably disposed in the rib through holes 104.

[0073] By integrating a shaft mounting hole 103 and a rib through hole 104 into the front shell 11 of the outer shell 1, a bidirectional constraint mechanism is formed for the connecting shaft 621 of the adjustment operation component. The shaft mounting hole 103 provides radial support for the connecting shaft 621, ensuring the coaxiality of the rotation of the adjustment operation component 6; the fit between the rib through hole 104 and the rib 622 restricts the rotational stroke of the adjustment operation component 6 in the circumferential angle, preventing the adjustment component 3 from jamming due to excessive rotation. The axial positioning of the adjustment operation component 6 is achieved by the structure of the rib 622 embedded in the rib through hole 104, preventing axial movement of the adjustment operation component 6.

[0074] Specifically, the front end shell 11 is integrally injection molded to form a shaft mounting hole 103 and a rib through hole 104. After the connecting shaft 621 is inserted into the shaft mounting hole 103, the protruding ribs 622 on both sides of the shaft 621 are embedded in the rib through hole 104. When the adjusting operating member 6 is rotated, the connecting shaft 621 drives the adjusting assembly 3 to rotate, and the protruding ribs 622 slide along their path within the rib through hole 104. The opening range of the rib through hole 104 determines the rotatable angle of the adjusting operating member 6, for example, it can be limited to 60° or 90°.

[0075] Furthermore, the rib through hole 104 is fan-shaped.

[0076] By setting the rib through-hole 104 to a fan-shaped geometry, the movement trajectory of the protruding rib 622 within the rib through-hole 104 precisely corresponds to the rotation angle of the adjusting operating component 6. The arc-shaped boundary of the fan not only limits the maximum rotational stroke of the protruding rib 622, but also ensures that the protruding rib 622 maintains a linear contact state during rotation through the guiding effect of the arc surfaces on both sides, avoiding axial movement caused by the radial clearance present in traditional circular through-holes. The special contour of the fan-shaped rib through-hole 104 and the cross-section of the protruding rib 622 form a complementary fit, achieving rotational degree of freedom control while dispersing the lateral stress generated during the operation of the adjusting operating component 6 through surface contact, effectively improving the stability and service life of the rotating mechanism.

[0077] Furthermore, the adjustment operation member 6 also includes a protrusion 63, and the front end shell 11 is provided with three grooves 105. The protrusion 63 cooperates with the grooves 105. When the adjustment operation member 6 is rotated, the protrusion 63 slides between the three grooves 105.

[0078] The three grooves 105 are distributed along the outer side of the rib through hole 104, and the angle of the central angle between adjacent grooves 105 is the same as the angle of the central angle between the forward air outlet 1021 and the reverse air outlet 1022 of the side air outlet 102.

[0079] By setting a protrusion 63 on the adjustment operating component 6 and engaging with three grooves 105 on the outer casing 1, precise positioning control is achieved when the adjustment operating component 6 rotates. The design of the protrusion 63 sliding between the grooves 105 provides tactile feedback during operation, helping the user perceive the rotation position of the adjustment operating component 6. By setting the central angle between adjacent grooves 105 to be the same as the central angle between the forward air outlet 1021 and the reverse air outlet 1022 of each group, it is ensured that when the adjustment operating component 6 rotates, each time the protrusion 63 moves to the position of a groove 105, the side air outlet 32 ​​is exactly aligned with the corresponding forward air outlet 1021, reverse air outlet 1022, or outer casing wall (specifically corresponding to clockwise airflow from the side air outlet, counterclockwise airflow from the side air outlet, and airflow from the front air outlet, respectively). The angular matching relationship between these structural features creates a mechanical interlock between the air outlet switching angle and the rotation angle of the operating adjustment component 6, which not only prevents positioning deviation caused by excessive rotation, but also ensures accurate correspondence between different air outlet modes.

[0080] Specifically, during the rotation of the adjusting component 6, the protrusion 63 is constrained by the side wall of the groove 105 as it slides along the groove 105, resulting in a phased change in resistance. When the adjusting component 6 rotates to the center position of the groove 105, the protrusion 63 and the groove 105 are engaged. The distribution of the three grooves 105 and the rotation path of the rib through hole 104 form a concentric circle layout, so that with each rotation of the groove 105 spacing, the air outlet switching angle of the adjusting component 3 just covers the three modes of forward, reverse, and front air outlet.

[0081] In some specific embodiments, the depth of the groove 105 can be set to 0.5-1.0 mm to ensure the clarity of the tactile feedback when the protrusion 63 slides, and the inclination angle of the sidewall of the groove 105 can be controlled between 45° and 60° to balance the demolding process requirements and the operating resistance.

[0082] Furthermore, the side wall of the outer casing 1 is provided with a flat plate portion 12, which is parallel to the axis of the outer casing 1, and the flat plate portion 12 is provided with the side air outlet 102.

[0083] The flat plate portion 12 refers to the planar area formed by the side wall of the outer casing 1. Specifically, it can be formed by stamping on the side wall of the outer casing 1; or the flat plate portion 12 can be designed as a detachable structure from the outer casing 1. This planar area is parallel to the axis of the outer casing 1 and serves to provide a mounting base surface perpendicular to the airflow direction for the side air outlet 102. The side air outlet 102 is provided on the flat plate portion 12 to guide the airflow out along the tangential direction of the surface of the flat plate portion.

[0084] Specifically, the airflow enters the adjustment component 3 after passing through the air duct 2. When the adjustment component 3 is rotated to the side air outlet 102 open state, the airflow is blown out from the side air outlet 102 of the flat plate 12. By spreading the hair flat on the flat plate 12, the hair can be straightened under the action of the heated airflow.

[0085] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
