[0002] Conventional hair dryers typically have a separate handle and operating unit, making them relatively long and wide, and large in overall size, resulting in poor portability and making them unsuitable for travel or portable use. Furthermore, prolonged operation can cause the heat generated by the heating unit to accelerate aging of internal components and shorten their service life. High temperatures can also be easily transferred to the handle, causing the handle to heat up and potentially resulting in burns to the hands.

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more clearly understood, the present invention will be described in more detail below in combination with the accompanying drawings and embodiments. It should be noted that, unless the embodiments of the present application contradict the technical features of other embodiments, they can be combined with each other.

[0035] In the following, many specific details are described to fully understand the present invention, but the scope of protection of the present invention is not limited to the specific embodiments disclosed below, as the present invention may be embodied in other ways different from those described herein.

[0036] 1-15, a hair drying device 10 and housing structure 100 according to several embodiments of the present invention will now be described.

[0037] As shown in FIGS. 1-2 and 5, a hair drying device 10 according to an embodiment of the present invention includes a housing structure 100, a heating member 200, and a blower assembly 300.

[0038] The housing structure 100 includes a mounting support 110 and a housing 120, and the housing 120 encases the mounting support 110, giving the housing structure 100 a columnar shape. As specifically described, the columnar housing structure 100 has a vertically extending structure, and its height is greater than its cross-sectional size. The present invention does not limit the specific shape of the housing structure 100, which may be a cylindrical shape, a rectangular pillar shape, an elliptical pillar shape, etc., and does not list them one by one, but may be designed according to actual needs. The outline of the housing structure 100 does not have to be a straight line, and local convex or concave portions may be provided on the sides as needed, as long as it is columnar overall.

[0039] As can be clearly seen, the external shape of the housing structure 100, i.e., the external shape of the hair drying device 10, is different from a typical hair drying device that is composed of a grip and an operating part. The present invention proposes a hair drying device 10 having an overall cylindrical external shape, which has a simpler external shape and a cleaner outline, thereby achieving a compact and portable device.

[0040] The interior of the mounting support 110 defines the outline of the main air passage 140 and the outlines of the main air inlet 141 and the main air outlet 142 that communicate the environment with the main air passage 140, the heating element 200 and the blower assembly 300 are respectively disposed in the main air passage 140, the blower assembly 300 being located below the heating element 200, and the heating element 200 being located upstream of the main air passage 140 relative to the blower assembly 300. The blower assembly 300 enables airflow to be driven from the main air inlet 141 through the main air passage 140 to the main air outlet 142, and by fully utilizing the vertical space of the columnar housing structure 100, on the one hand, it helps to reduce the cross-sectional area of ​​the device and realize a compact design of the device, and on the other hand, the user will grip both peripheral portions of the housing structure 100, and the smaller cross-section helps to improve the user's gripping feel.

[0041] The housing 120 has a first opening 121 and a second opening 122, and the housing 120 and the mounting support 110 are spaced apart at least at the positions of the blower assembly 300 and the heating element 200 to define a heat dissipation air passage 150, thereby allowing airflow from the second opening 122 through the heat dissipation air passage 150 to the first opening 121.

[0042] In the hair drying device 10 according to the present invention, the housing 120 and the mounting support 110 are spaced apart at least at the positions of the blower assembly 300 and the heating element 200, and effectively isolate the heating element 200 and the blower assembly 300 from the housing 120 in the main air passage 140, thereby helping to reduce the heat transferred to the housing 120 by the blower assembly 200 and the heating element 300 during operation. In addition, the space between the housing 120 and the mounting support 110 forms a heat dissipation air passage 150, which helps to reduce the heat transfer of the blower assembly 300 to the housing 120. When in operation, air flows from the second opening 122 through the heat dissipation airway 150 to the first opening 121, carrying away the heat generated during the operation of the fan assembly 300 and the heating element 200. This continuously prevents heat buildup inside the housing structure 100 through convection and significantly reduces the surface temperature of the device, thereby preventing users from getting burns to their hands when holding the device. This not only improves the safety and comfort of using the device, but also reduces damage to internal parts caused by high temperatures and delays material aging, thereby extending the service life of the hair drying device 10.

[0043] The main air duct 140 and the heat dissipation air duct 150 are then arranged according to at least two embodiments.

[0044] In one embodiment, the main air duct 140 and the heat dissipation air duct 150 are two independent air ducts, and the positions of the first opening 121 and the main air outlet 142 do not overlap, and the positions of the first opening 122 and the main air inlet 141 do not overlap.

[0045] In another embodiment, referring to Figures 3 and 5, the positions of the first opening 121 and the main air outlet 142 at least partially overlap, and the mounting support 110 is provided with at least one through hole 1101, so that air flows from the second opening 122 through the heat dissipation airway 150 and the through hole 1101 into the main airway 140.

[0046] Preferably, the positions of the first opening 121 and the main air outlet 142 completely overlap.

[0047] The design in which the first opening 121 of the heat-dissipating air duct 150 overlaps with the main air outlet 142, and the through-hole 1101 is provided in the mounting support 110 to connect the heat-dissipating air duct 150 with the main air duct 140 has the following advantages: first, the second opening 122 of the heat-dissipating air duct 150 can be used as an auxiliary air inlet for the main air duct 140, and the external airflow can pass through it to enter the heat-dissipating air duct 150 and then be blown out of the heating element 200 and the blower assembly 300. The heat generated from the main air duct 140 is absorbed, and flows through the through-holes 1101 into the main air duct 140, and after mixing with the airflow in the main air duct 140, is discharged from the main air outlet 142 (or the first opening 121), thereby achieving heat dissipation in the housing 120 and adding an auxiliary airflow to the main air duct 140, increasing the overall airflow of the main air duct 140 and avoiding the loss of the airflow required for heat dissipation. Second, in the hot air mode, the airflow in the heat dissipation air duct 150 and absorbs heat to form a preheated airflow, which mixes with the cool air in the main air duct 140 and enters the heating element 200, thereby reducing the direct energy consumption of the heating element 200, reducing its load and improving heating efficiency, and enabling the temperature of the air blown out to be kept stable and uniform. Third, by integrating the first opening 121 with the main air outlet 142, the number of openings in the housing 120 is reduced, simplifying the internal air duct structure and realizing a compact design for the entire device. In addition, since the airflow in the main air duct 140 and the heat dissipation air duct can be driven by the action of a single fan element 300, the components for independently driving the heat dissipation elements are eliminated, further reducing hardware costs and assembly complexity, and ensuring heat dissipation performance, air blowing stability, and operational safety, thereby realizing a smaller, lighter, and more reliable device.

[0048] 4 and 5, the through-hole 1101 is located below the fan assembly 300, and the position of the second opening 122 is higher than the position of the heating member 200. More specifically, the heat dissipation air passage 150 extends downward from the position of the second opening 122 in the vertical direction along the housing 120 to the position of the fan assembly 300.

[0049] The design of locating the through-hole 1101 below the blower assembly 300 and locating the second opening 122 higher than the heating element 200 allows the heat-dissipating airflow to flow from top to bottom through the areas corresponding to the heating element 200 and the blower assembly 300, and allows the heat-generating positions to be completely covered by the heat-dissipating airway 150, preventing localized high temperature accumulation and improving heat dissipation efficiency. In addition, the design of locating the second opening 122 at an upper position keeps it away from the middle and lower areas that are frequently touched by the palm of the user's hand when holding the hair drying device 10, effectively reducing the possibility of air blowing being obstructed due to the second opening 122 being blocked by the gripping action. This allows the airflow in the heat-dissipating airway 150 to flow smoothly and avoids a decrease in heat dissipation performance or internal heat stagnation due to insufficient air blowing.

[0050] 8 and 11, in one embodiment, the mounting support 110 defines, from top to bottom, a first section 111A, a transitional section 112A, and a second section 113A, the second section 113A circumferentially interlocks with the housing 120, the heat dissipation airway 150 is defined between the first section 111A and the housing 120, the transitional section 112A connects the first section 111A and the second section 113A, and the transitional section 112A is provided with a through hole 1101. More specifically, the blower assembly 300 and the heating element 200 are installed in the first section 111A, the transitional section 112A is a slanted wall that slopes from the first section 111A toward the first section 113A, and the transitional section 112A is provided with a plurality of through holes 1101 at intervals in the circumferential direction.

[0051] The design of the mounting support 110 divided into sections from top to bottom forms a heat dissipation airway 150 between the first section 111A and the housing 120. By widening the heat dissipation airway 150, heat can be dissipated in more positions, ensuring a good heat dissipation effect. When the second section 113A is fitted to the outer shell 120 in the circumferential direction, the assembly precision of the mounting assembly 110 and the housing 120 is improved. The through-hole 1101 is provided in the transition section 112A and is located in the downstream airflow path. The airflow flows from the heat dissipation airway 150 to the main airway 140 under the synergistic effect of gravity and the negative pressure of the fan, forming a stepped spatial arrangement from top to bottom. This allows the heat dissipation airway 150 to be compactly integrated with the main airway 140 in a limited internal space, reducing the structural complexity and improving the convenience of manufacturing and assembly.

[0052] Further, referring to Figures 6 and 8, the second section 113A is provided with a main air outlet 142, and the hair drying device 10 further includes a control component 400, which is disposed within the second section 113A.

[0053] Compared with the first section 111A spaced apart in the housing 120, the second section 113A circumferentially interlocked with the housing 120 has a larger radial space, and locating the main airway 140 in the second section 113A helps widen the main airway 140 and increase the amount of air blown into the main airway 140. In addition, integrating the main air inlet 141 and the control component 400 within the second space 113A realizes a compact layout of the internal structure of the device. As can be seen, the heat generated during operation of the control component 400 is relatively small, and the heat is naturally dissipated along with the airflow through the main airway 140 and the second section 113A, which simplifies the structural design and ensures the stability of the operation of the control component 400.

[0054] It should be noted that the above design of the second opening 122 and the through-hole 1101 is only one of the preferred embodiments of the present invention. In another embodiment, the through-hole 1101 is located above the heating element 200, and the second opening 122 is located lower than the heating element 200, so that the airflow in the heat-dissipating airway 150 flows from bottom to top.

[0055] 4, in one embodiment, the second opening 122 is located at the top of the housing 120, and the first opening 121 is located on one side opposite the second opening 122. The design of arranging the second opening 122 and the first opening 121 at an upper position keeps them away from the middle and lower areas that are frequently touched by the palm of a user's hand when gripping the hair drying device 10, effectively reducing the possibility of air blowing being obstructed due to the second opening 122 and the first opening 121 being blocked by the gripping action, thereby ensuring smooth airflow in the heat dissipation air channels 150 and ensuring heat dissipation efficiency and stable air blowing. In addition, concentrating the openings at an upper position makes the appearance of the device more concise and neat, improving the aesthetic design, avoiding the problem of reduced mechanical strength caused by porous distribution, and further enhancing structural reliability.

[0056] Preferably, the second opening 122 has a lattice structure and / or a porous structure to prevent foreign matter from entering the interior of the device.

[0057] 4 and 7, the outer shell 120 protrudes outward in the area of ​​the second opening 122. The protruding structure design has a preventive effect, and the protruding physical contour guides the palm of the hand to naturally fit under the protruding area when holding the hair drying device 10, thereby preventing the hand from covering the second opening 122 and blocking air blowing, and ensuring a continuous and stable inflow of heat-dissipating airflow.

[0058] An installation space 151 is formed between the protruding portion of the housing 120 and the installation support 110 , and the hair drying device 10 further includes a negative ion generating component 500 , which is located in the installation space 151 .

[0059] Specifically, the negative ion generating component 500 includes a negative ion generator and two discharge needles 520 connected to the negative ion generator. In one possible embodiment, the two discharge needles 520 are installed on the outer wall surface of the mounting support 110 and extend into the main air duct 140 by drilling the wall of the mounting support 110, so that the discharge needles 520 can directly emit ions when placed in the main air duct 140 and be discharged together with the airflow in the main air duct 140.

[0060] The negative ion generating component 500 assembled in the hair drying device 10 realizes functional expansion, and the ions emitted from the negative ion generating component 500 are discharged together with the airflow from the main air duct 140 or the heat dissipation air duct 150, improving the softness and anti-static effect of hair during drying. In addition, the additional space formed by the protrusion of the housing 120 provides a reasonable accommodation area for the negative ion generating component 500, realizing a compact layout and miniaturized design of the device. In addition, the negative ion generating component 500 is also located within the heat dissipation air duct 150, which allows the heat dissipation air duct 150 to quickly dissipate heat for the negative ion generating component 500, thereby extending the service life of the negative ion generating component 500 and further reducing the operating temperature of the housing 120.

[0061] Furthermore, by recessing the position of the mounting support 110 corresponding to the negative ion generating component 500 in a direction away from the housing 120, the space for mounting the negative ion generating component 500 within the heat dissipation air duct 150 is further expanded, making full use of the space within the device and making the arrangement more compact.

[0062] In one embodiment, referring to FIG. 6 , the mounting support 110 also defines the contours of a water ion airway 160, which has a water ion air inlet 161 and a water ion air outlet 162 that communicate directly or indirectly with the environment, and the hair drying device 10 further comprises a water ion module, which is installed in the water ion airway 160.

[0063] The water ion module is added to release negative ions containing water molecules that adhere to the surface of the hair, thereby enhancing the moisturizing effect, neutralizing static electricity, improving hair quality, and enhancing the user experience. In addition, the independent water ion airway 160 communicates directly or indirectly with the environment, providing a stable airflow input and output path for the water ion module, preventing the hot air from the main airway 140 from interfering with the water ion generation environment and ensuring uniformity in the concentration and release of water ions.

[0064] Furthermore, since the water ion air inlet 161 is connected to the main air duct 140 and located below the heating member 200, the airflow branches off in the main air duct 140 and flows through the air inlet toward the water ion air duct 160. Referring to Figure 10, the water ion air inlet 161 and the water ion air outlet 162 are located on the same side of the mounting support 110, independent of each other.

[0065] By arranging the water ion air inlet 161 below the heating element 200 and communicating with the main air duct 140, the unheated cold airflow in the main air duct 140 is diverted to the water ion air duct 160, preventing the hot airflow from interfering with the operating environment of the water ion module and ensuring the concentration and stability of water ion generation. In addition, by indirectly connecting the water ion air duct 160 to the environment via the main air outlet 142, the number of openings in the housing 120 is reduced, simplifying the design of the device structure. Furthermore, by independently locating the water ion air inlet 161 and the water ion air outlet 162 on the same side, water ions and heated hot air from the main air duct 140 can be blown onto the hair simultaneously, optimizing the drying range and making hair care more efficient and improving the user's experience.

[0066] 3 and 15, in one alternative embodiment, an air blowing structure 130 is provided on the housing 120, and the air blowing structure 130 has two openings 131 that are independent of each other, one of which communicates with the main air outlet 142 and the other of which communicates with the water ion air outlet 162. The inner wall of the opening 131 extends to perform a flow guiding function, so that the airflow discharged through the air blowing structure 130 is reliably blown onto the hair.

[0067] Specifically, the main air outlet 142 is strip-shaped, and the opening 131 corresponding to the main air outlet 142 is aligned with the main air outlet 142. On the one hand, designing the main air outlet 142 in a strip shape ensures the amount of air blown out, and is more adaptable to the shape of the columnar housing structure 100, which helps to reduce the volume of the device; on the other hand, the strip-shaped main air outlet 142 linearizes the amount of air blown out, making it convenient for the user to dry and style their hair, and potentially eliminating the need for flat-mouthed accessories.

[0068] More specifically, in the design where the heat dissipation airway 150 and the main airway 140 share the same air outlet, the air outlet structure 130 is connected to the mounting support 110, the first opening 121 provided in the housing 120 fits into the air outlet structure 130, and the first opening 121 surrounds the air outlet structure 130, so that the whole device has a simpler outer shape and a cleaner outline.

[0069] In one embodiment, referring to Figures 9 and 12, the mounting support 110 has a hollow main body 111B and a convex wall structure 112B protruding from the outer wall surface of the main body 111B, the inside of the main body 111B defines the outline of the main airway 140, the main body 111B is spaced apart from the housing 120 to define the outline of the heat dissipation airway 150, and the convex wall structure 112B and the outer wall surface of the main body 111B are surrounded by the outer wall surface of the main body 111B to form a water ion airway 160.

[0070] A part of the convex wall structure 112B protruding from the outer wall surface of the main body 111B surrounds the outer wall of the main body 111B to form the water ion airway 160, and also forms the heat dissipation airway 150 by utilizing the gap between the housing 120 and the main body 111B. This allows for a compact arrangement of the main airway 140, the water ion airway 160 and the heat dissipation airway 150 through a spatial nesting relationship, reduces the number of independent airway components and the space they occupy, makes maximum use of space, and reduces the size of the entire device, thereby achieving multi-functionality, miniaturization and portability of the device.

[0071] 13, the main air inlet 141 is located at the lower end of the main body 111B, and the main air outlet 142 is located at the side wall at the upper end of the main body 111B. A first straight wall 111B1 and a first guide wall 111B2 are formed in a part of the main body 111B facing the convex wall structure 112B, and one end of the first guide wall 111B2 is connected to the first straight wall 111B1 and the other end curves toward the main air outlet 142, and the inner surface of the first guide wall 111B2 guides the airflow from the main air inlet 141 to the main air outlet 142.

[0072] The convex wall structure 112B is formed with a second straight wall 112B1 and a second guide wall 112B2, one end of the second guide wall 112B2 is connected to the second straight wall 112B1 and the other end is curved and extends toward the water ionized air outlet 162, the second straight wall 112B1 faces the first straight wall 111B1 and part of the first guide wall 111B2, and the second guide wall 112B2 faces the first guide wall 111B2.

[0073] The convex wall structure 112B further includes a ring wall structure 112B3, which is located on the top of the first guiding wall 111B2 and connects the first guiding wall 111B2 and the second guiding wall 112B2. The receiving space 163 is surrounded by the ring wall structure 112B3, and the water ion components are installed in the receiving space 163.

[0074] The first guiding wall 111B2 guides the airflow in the main air duct 140 from the main air inlet 141 to the main air outlet 142, the second straight wall 112B1 faces the first straight wall 111B1 and a part of the first guiding wall 111B2, and the second guiding wall 112B2 faces the first guiding wall 111B2, thereby widening the radius of the water ion duct 160 from upstream to downstream, reducing the flow rate of the airflow from upstream to downstream, lengthening the contact time with the water ion module, and improving the efficiency of water ion generation and transportation. In addition, the first guiding wall 111B2 and the second guiding wall 112B2 are curved to free up space at the top of the housing structure 100, and the water ion components are concentrated in the accommodation space 163 surrounded by the ring wall structure 112B3 at the top, making full use of the top space and making the overall structure of the device more compact.

[0075] In one embodiment, referring to Figures 12 and 14, the mounting support 110 has a first casing 110A and a second casing 110B, and the first casing 110A is joined to the second casing 110B to form a main air passage 140 and a water ion air passage 160, and the joining line extends along the axial direction of the mounting support 110.

[0076] The first casing 110A is axially joined to the second casing 110B, which simplifies the structure and assembly process of the mounting support 110; the two casings are directly joined via an axially extending joint line, which reduces the difficulty of assembly; after joining, the main airway 140 and the water ion airway 160 form complete flow path contours synchronously, ensuring the airflow path's tightness and continuity, and avoiding airflow leakage or turbulent interference caused by joining multiple parts.

[0077] In one embodiment, referring to Figures 1 and 15, an air blowing structure 123 is provided at the bottom end of the housing 120, the mounting support 110 is hollow, and its bottom end defines a main air blowing port 141, and the air blowing structure 123 faces the main air blowing port 141.

[0078] The bottom air inlet design, compared to the side air inlet design, places the main air outlet 142 farther from the user's grip area, preventing air inlet obstruction due to obstruction of the hand, particularly for small hair drying devices 10, ensuring a stable airflow for the main air duct 140, reducing the probability of contact with hair and reducing the possibility of hair being accidentally sucked in or tangled during operation, thereby improving safety in use. In addition, the bottom main air inlet 141 has a certain blind spot effect, making the side of the housing 120 more perfect and the appearance of the device more concise.

[0079] Furthermore, the hair drying device 10 further comprises a filtering structure, and the main air inlet 141 is provided with a lattice structure or a porous structure, and the filtering structure is sandwiched and fixed between the air inlet structure 123 and the main air inlet 141.

[0080] 1-15, another aspect of the present invention provides a housing structure 100. The housing structure 100 has a columnar shape and includes a mounting support 110 and a housing 120.

[0081] The interior of the mounting support 110 defines the outline of a main air duct 140 and the outline of a main air inlet 141 and a main air outlet 142 that connect the environment to the main air duct 140, and the interior of the main air duct 140 defines the outline of a first space 1102 for accommodating the heating element 200 and a second space 1103 for accommodating the blower assembly 300, the second space 1103 being located below the first space 1102.

[0082] The housing 120 encases the mounting support 110, and the housing 120 has a first opening 121 and a second opening 122. The housing 120 and the mounting support 110 are spaced apart at least at the positions of the first space 1102 and the second space 1103 to define the contours of the heat dissipation air passage 150, thereby allowing airflow from the second opening 122 through the heat dissipation air passage 150 to the first opening 121.

[0083] The housing structure 100 of the present invention is applied to a hair drying device 10, and its specific structure and effects can be referred to the embodiment of the hair drying device 10 described above, and will not be repeated here.

[0084] The technical features of the above embodiments may be combined in any manner, and for the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
