Description

An accessory and drying assembly Technical Field

[0001] The present application relates to the field of drying equipment, and in particular to an accessory and a drying component. Background Art

[0002] Drying equipment that can simultaneously output infrared radiation and hot air exists in the existing technology. However, conventional nozzles are designed solely for thermal resistance to hot air. When installed in these drying devices, certain areas of the nozzle absorb both the infrared radiation and the hot air, rapidly heating up. When this temperature exceeds its thermal resistance limit, it can deform or melt, damaging the nozzle. Furthermore, overheated nozzles can easily cause burns and other safety hazards.

[0003] Summary of the Invention

[0004] The present application provides an accessory and a drying assembly, aiming to solve the problem in the prior art that the air nozzle is easily damaged by overheating.

[0005] The accessory provided in the present application is installed on a drying device, and the drying device is capable of outputting airflow and infrared radiation. The accessory includes a mounting portion, an airflow portion and a flow guide member. The mounting portion is used to be installed on the drying device. The airflow portion has an air inlet, a flow guide cavity and an air outlet. A hollow portion is formed between the airflow portion and the mounting portion, and the flow guide member is located in the flow guide cavity; wherein the mounting portion and the airflow portion are interconnected by a first connecting member, and the airflow portion and the flow guide member are interconnected by a second connecting member.

[0006] The present application also provides a drying component, including a drying device and the above-mentioned accessories, wherein the end of the drying device has an air outlet portion for outputting air flow and a radiation portion for outputting infrared radiation; the accessory can be detachably installed on the drying device, the air inlet corresponds to the air outlet portion, and the hollow portion corresponds to at least part of the radiation portion.

[0007] When used with the drying equipment, the accessory in this application forms independent airflow and infrared radiation transmission paths. There are no areas that are both traversed by hot airflow and exposed to infrared radiation, thus avoiding the risk of rapid local overheating caused by simultaneous absorption of both airflow heat and infrared radiation energy. The first and second connectors not only interconnect and support the airflow portion, the mounting portion, and the flow guide, but also form a heat transfer path. When the accessory overheats locally, the heat can be dispersed throughout the entire accessory, thereby avoiding damage from overheating.

[0025] As shown in FIG. 1 a , FIG. 1 b , FIG. 2 , and FIG. 3 , some embodiments of the present application provide an accessory 10 that can be detachably mounted on a drying device 20 for adjusting the airflow of the drying device 20 .

[0026] The drying device 20 involved in the present application has a radiation component and an airflow component, and its end has an air outlet 22 for outputting airflow and a radiation part 21 for outputting infrared radiation. When the drying device 20 is in operation, the airflow or hot airflow is output from the air outlet 22, and the infrared radiation is output from the radiation part 21. After the two are transmitted along a preset transmission path, they act on the object to be dried to dry it. In order to ensure a better drying effect, the airflow and infrared radiation output by the drying device 20 are designed to form a roughly overlapping coverage area at a preset distance, and the water in the coverage area is quickly evaporated by the combined action of wind, light, and heat. Taking the object to be dried as hair as an example, when the user uses the drying device 20 to blow-dry the hair, the infrared radiation can protect the hair from damage caused by high-temperature baking.

[0027] After attaching the accessory 10 to the drying device 20, it can adjust the airflow of the drying device 20. Specifically, the accessory 10 can change at least one airflow parameter of the airflow output by the drying device 20, including wind speed, airflow direction, airflow shape, transmission path, and degree of divergence or convergence. Taking the process of blow-drying hair using the drying device 20 as an example, different airflows can achieve different effects. For example, a flat, high-temperature airflow is suitable for styling hair, a diffuse, low-speed airflow can create a fluffy effect on blow-dried hair, and a convergent, high-speed airflow can keep hair straight and smooth during the blow-drying process.

[0028] Furthermore, since the drying device 20 also emits infrared radiation, to ensure that the objects being dried are simultaneously exposed to the combined effects of wind, light, and heat, the accessory 10 should not only adjust the airflow as needed but also minimize the obstruction of infrared radiation. In other words, the accessory 10 is designed to allow as much infrared radiation as possible to pass through while still being able to adjust the airflow.

[0029] In the various figures of this application, solid arrows indicate portions of the transmission path of infrared radiation, and dashed arrows indicate portions of the transmission path of airflow. It should be noted that, although the infrared radiation and airflow output by drying device 20 have different divergence angles, their transmission directions are generally the same, both denoted by the airflow direction x. The following describes the related structures of accessory 10 and drying device 20 in conjunction with the airflow and infrared radiation transmission paths.

[0030] Referring to Figures 2, 3 and 4, the accessory 10 specifically includes a mounting portion 11, an airflow portion 12 and a flow guide 13. Among them, the mounting portion 11 is used to be mounted to the drying device 20 so that the accessory 10 remains mounted with the drying device 20. The mounting portion 11 can at least provide sufficient mounting strength and positioning accuracy so that the accessory 10 can remain stable when used with the drying device 20. In some embodiments, the accessory 10 can be mounted with the drying device 20 by rotating it axially at any angle. The mounting portion 11 can specifically be mounted with the drying device 20 using magnetic attraction, threads, annular buckles, etc., and its specific structure is not the focus of this application. Unless otherwise specified below, the accessory 10 and the drying device 20 are in a state of being mounted with each other, and the other parts on the accessory 10 form an installation and connection relationship with the mounting portion 11, which can be regarded as these parts being able to be positioned relative to the drying device 20 and being in a preset position.

[0031] The airflow section 12 has an air inlet a, a guide cavity 121, and an air outlet b. The position of the air inlet a corresponds to the air outlet 22 of the drying device 20. The guide member 13 is located within the guide cavity 121. The airflow output from the drying device 20 enters the airflow section 12 through the air inlet a, flows along the outer surface of the guide member 13 and the inner surface of the guide cavity 121, and finally leaves the attachment 10 through the air outlet b and is output to the object to be dried. The shape and size of the guide member 13, the guide cavity 121, and the air outlet b all affect the airflow parameters, thereby achieving the purpose of adjusting the airflow of the drying device 20.

[0032] A hollow portion c is formed between the air flow portion 12 and the mounting portion 11, and the hollow portion c corresponds to at least a portion of the radiation portion 21. At least a portion of the infrared radiation output from the radiation portion 21 of the drying device 20 can pass through the hollow portion c and be output to the object to be dried.

[0033] As shown in Figure 4, the mounting portion 11 and the airflow portion 12 are connected to each other via a first connector 141. Because a hollow portion c is formed between the mounting portion 11 and the airflow portion 12, the first connector 141 itself spans the hollow portion c. At least partially within the transmission path of infrared radiation, it absorbs infrared radiation energy and generates a temperature rise. Therefore, the total amount of infrared radiation that can pass through the attachment 10 and reach the object to be dried is roughly equal to the total amount of infrared radiation that enters the hollow portion c, minus the portion blocked by the first connector 141. As previously mentioned, the attachment 10 is designed to transmit as much infrared radiation as possible. Therefore, in the airflow direction x, no other structure other than the first connector 141 is located within the hollow portion c. Alternatively, if other structure is located within the hollow portion c, it is positioned so that it roughly overlaps with the first connector 141 in the airflow direction x, thereby minimizing infrared radiation obstruction.

[0034] The airflow portion 12 and the flow guide 13 are connected to each other via a second connector 142. At least a portion of the second connector 142 is located within the airflow transmission path and exchanges heat with the airflow. When the drying device 20 outputs a hot air flow, the second connector 142 absorbs a portion of the heat from the hot air flow, causing the temperature to rise.

[0035] As shown in Figures 5 and 6, different lines are used to mark the parts covered by the airflow and infrared radiation at the air inlet a and the air outlet b. Combined with Figure 4, independent airflow transmission paths and infrared radiation transmission paths are formed in the accessory 10, specifically:

[0036] The guide cavity 121 in the air flow section 12 forms a transmission path for the air flow. During the operation of the drying device 20, when the output air flow flows along the above-mentioned transmission path, it will flow through the inner surface of the air flow section 12, the outer surface of the guide member 13, and the outer surface of the second connecting member 142. When the drying device 20 outputs hot air flow, these areas will absorb the heat of the air flow and cause the temperature to rise. In this application, "area" means at least a part of a certain surface. Even at the same position on the same structure, different surfaces (such as the inner and outer surfaces of the air flow section 12) are different areas, which will not be repeated below.

[0037] The hollow portion c between the exterior of the airflow portion 12 and the mounting portion 11 forms a transmission path for infrared radiation. During operation, the drying apparatus 20 emits infrared radiation that impinges on at least a portion of the exterior surface of the airflow portion 12, at least a portion of the exterior surface of the mounting portion 11, and at least a portion of the exterior surface of the first connector 141. These areas absorb the infrared radiation energy, causing a temperature rise.

[0038] As can be seen, in each of the aforementioned structures, the air guide 13 and the second connector 142 are affected only by airflow, while the mounting portion 11 and the first connector 141 are affected only by infrared radiation. While the airflow portion 12 is affected by both airflow and infrared radiation, the areas where these two effects occur on the airflow portion 12 do not overlap. Part of the outer surface of the airflow portion 12 is affected by infrared radiation, while the inner surface is affected by airflow.

[0039] In other words, when the drying device 20 outputs hot air and infrared radiation, no area on the entire attachment 10 is simultaneously exposed to both the hot air flow and the infrared radiation. This prevents the risk of localized areas absorbing both the airflow heat and infrared radiation energy simultaneously, leading to rapid overheating. This reduces the overall heat resistance requirements of the attachment 10 during design, thereby reducing its cost.

[0040] In addition, the first connecting member 141 and the second connecting member 142 are respectively located in the infrared radiation transmission path and the airflow transmission path. The two not only realize the function of supporting and connecting the corresponding structures, but also form a heat transfer path to disperse the heat absorbed from infrared radiation or hot air flow, so as to further avoid local overheating of the accessory 10.

[0041] Specifically, when the drying device 20 outputs a relatively high-temperature hot air flow, the hot air flow heats any of the inner surface of the air flow portion 12, the flow guide 13, and the second connector 142 to a superheated state. This heat is then transferred along the air flow portion 12 to the first connector 141, and then from the first connector 141 to the mounting portion 11, thereby dissipating the heat from the hot air flow throughout the accessory 10. This not only reduces the local temperature rise of the accessory 10 but also increases the heat dissipation area.

[0042] Similarly, when the drying device 20 outputs high-power infrared radiation, the outer surface of the airflow portion 12 or the first connector 141 is heated to overheating by the infrared radiation. This heat is then transferred along the first connector 141 to the mounting portion 11 and the airflow portion 12, and then from the airflow portion 12 to the flow guide 13 through the second connector 142, thereby dispersing the heat from the infrared radiation throughout the accessory 10. This not only reduces the local temperature rise of the accessory 10, but also increases the heat dissipation area.

[0043] When the drying device 20 outputs a relatively low-temperature hot airflow or normal-temperature airflow, the heat exchange process between the airflow and the areas passing through it acts as a heat dissipation process, causing the inner surface of the airflow section 12, the flow guide 13, and the second connecting member 142 to continuously dissipate heat. Heat absorbed from infrared radiation by the outer surface of the airflow section 12 and the first connecting member 141 is transferred to the second connecting member 142. The heat dissipated by the airflow rapidly cools the second connecting member 142, thereby reducing the overall temperature rise of the accessory 10.

[0044] In summary, when the accessory 10 provided in the embodiments of the present application is used in conjunction with the drying device 20, the accessory 10 can form independent airflow and infrared radiation transmission paths, preventing localized areas from being simultaneously heated by the hot airflow and infrared radiation, leading to rapid temperature rise. Furthermore, the first connector 141 and the second connector 142 can disperse localized high temperatures in the accessory 10 throughout the entire accessory 10, further preventing localized overheating of the accessory 10.

[0045] In some more practical embodiments, heat-resistant materials may be provided in the area of ​​the accessory 10 where the airflow flows, and reflective materials may be provided in the area exposed to infrared radiation, so as to more specifically reduce the temperature rise or increase the heat resistance.

[0046] In some more practical embodiments, the outer surface of the airflow portion 12 is coated to have a higher reflectivity, thereby reducing the infrared radiation absorbed by the outer surface of the airflow portion 12 and achieving the purpose of reducing temperature rise.

[0047] As shown in Figures 1a and 1b , some embodiments of the present application further provide a drying assembly 100 comprising the aforementioned drying device 20 and an accessory 10. Multiple accessories 10 may be provided, each modifying airflow parameters in a different manner, allowing the user to select the appropriate accessory 10 and install it on the drying device 20 as needed. As previously mentioned, during use of the drying assembly 100, the accessory 10 prevents the risk of rapid overheating due to localized absorption of both airflow heat and infrared radiation energy, thereby providing excellent overall heat resistance.

[0048] In some specific embodiments as shown in Figure 5, the first connector 141 and the second connector 142 are connected to opposite side walls at the same position of the airflow portion 12. Although they are not in direct contact, they can transfer heat to each other through the side walls of the airflow portion 12, thereby improving the efficiency of heat transfer between the first connector 141 and the second connector 142. In other specific embodiments not shown, the first connector 141 and the second connector 142 are directly connected, contacting and mounted with each other, which has a higher heat transfer efficiency. In other embodiments, a portion of the first connector 141 and the second connector 142 are in contact and connected, and the other portions are respectively connected to opposite side walls at the same position of the airflow portion 12, and the first connector 141 and the second connector 142 can also transfer heat to each other. In other embodiments, the first connector 141 and the second connector 142 are two parts of an integral connector, which can also be understood as the integral connector directly connecting the mounting portion 11 and the flow guide 13, and the airflow portion 12 is also connected to the integral connector. In the various embodiments described above, thermal coupling is formed between the first connector 141 and the second connector 142, allowing heat to be transferred from the higher temperature connector to the lower temperature connector. This allows heat to be quickly distributed throughout the accessory 10 along the transfer path formed by the first connector 141 and the second connector 142.

[0049] In some embodiments, as shown in FIG5 , the first and second connectors 141, 142 extend in the same direction on any plane perpendicular to the axis of the accessory 10. This creates a linear heat transfer path formed by the first and second connectors 141, 142, enabling heat to be efficiently transferred outward along the first and second connectors 141, 142 and distributed throughout the accessory 10, thereby reducing the risk of localized overheating. In other embodiments, the first and second connectors 141, 142 may extend in different directions, such as perpendicular to each other or at an angle to each other, to accommodate different structural design requirements.

[0050] In some embodiments as shown in FIG. 5 , on any plane perpendicular to the axis of the accessory 10, the first connector 141 and the second connector 142 extend radially along the accessory 10 to form the shortest heat transfer path between the mounting portion 11, the airflow portion 12, and the flow guide 13, enabling heat to be transferred among these three with higher efficiency and further dispersed to the entire accessory 10, thereby reducing the risk of local overheating.

[0051] In some embodiments, as shown in Figure 5, there are two first connectors 141 and two second connectors 142. In any plane perpendicular to the axis of the accessory 10, all first connectors 141 and second connectors 142 are arranged and symmetrically distributed along radial lines of the accessory 10. Taking the illustrated direction as an example, the upper and lower halves of the accessory 10 each have a first connector 141 and a second connector 142. Heat from various areas of the upper half of the accessory 10 is transferred and dispersed via the first connectors 141 and second connectors 142 located in the upper half; heat from various areas of the lower half of the accessory 10 is transferred and dispersed via the first connectors 141 and second connectors 142 located in the lower half.

[0052] In some more specific embodiments, the cross-sectional shape of the accessory 10 in the airflow direction x is circular, and all the first connecting members 141 and the second connecting members 142 are arranged along the diameter of the circle.

[0053] It is easy to understand that the greater the number of first connectors 141 and second connectors 142, the higher the heat transfer efficiency and the corresponding structural strength, but the degree of blocking infrared radiation and airflow is also higher. In different embodiments, the first connectors 141 and the second connectors 142 can be designed to other numbers, such as three, five, six, etc., based on the actual connection strength requirements and heat transfer requirements. In other embodiments, the number of first connectors 141 and the second connectors 142 can also be different, for example, the number of first connectors 141 is four and the number of second connectors 142 is two, and the two first connectors 141 are directly or indirectly connected to the one second connector 142 to form a thermal coupling.

[0054] The infrared radiation output by the drying device 20 diffuses along its transmission path, gradually reducing its power density. Therefore, the closer the attachment 10 is to the radiating portion 21 of the drying device 20, the higher the power density of the received infrared radiation and the greater the temperature rise. To reduce the temperature rise of the first connector 141 due to infrared radiation, in some embodiments, the shape of the first connector 141 is specially designed to maximize the distance between the entire first connector 141 and the radiating portion 21 in the airflow direction x without changing its installation method or structural strength.

[0055] Specifically, in the embodiment shown in Figure 4 , the portion of the first connector 141 facing the radiating portion 21 is curved in an arched shape along the airflow direction x, with the area closer to the apex of the arch becoming increasingly distant from the radiating portion 21. Compared to a straight extension, the arched first connector 141 maintains the original positions of its two end points, increasing the distance between the central region and the radiating portion 21 along the airflow direction x without changing the original mounting position and mounting method relative to the mounting portion 11 and airflow portion 12, thereby reducing the overall temperature rise due to infrared radiation.

[0056] In other embodiments, the portion of the first connector 141 facing the radiating portion 21 can be designed to extend along an inclined straight line or curve, with its first end positioned relatively close to the radiating portion 21 and its second end positioned relatively far away from the radiating portion 21. As the first end points toward the second end, the first connector 141 gradually moves away from the radiating portion 21. This can also increase the distance between the entire first connector 141 and the radiating portion 21 in the airflow direction x, thereby reducing temperature rise.

[0057] In some more specific embodiments, the first connector 141 is formed of a heat-resistant material that can withstand high temperatures without deformation. In some more specific embodiments, the first connector 141 is formed of a reflective material, or has a reflective surface formed on the surface by coating, laminating, etc., which can reflect most infrared radiation, reduce the amount of infrared radiation absorbed, and thus reduce the temperature rise of the first connector 141.

[0058] The hot air flow output by the drying device 20 diffuses along its transmission path, gradually reducing its power density. Therefore, the closer the accessory 10 is to the air outlet 22 of the drying device 20, the greater the temperature rise caused by the hot air flow. To reduce the temperature rise of the second connector 142 due to the hot air flow, in some embodiments, the shape of the second connector 142 is specially designed to maximize the distance between the second connector 142 and the air outlet 22 in the airflow direction x without changing its installation method or structural strength.

[0059] Specifically, in some embodiments shown in Figures 4 and 8 , the portion of the second connector 142 facing the air outlet 22 is designed to be curved in an arched shape along the airflow direction x. Compared to a straight extension, the arched second connector 142 can maintain the original positions of its two end points. Without changing the original installation position and installation method with the airflow portion 12 and the air guide 13, the distance between the second connector 142 and the air outlet 22 in the airflow direction x is increased, thereby reducing the overall temperature rise affected by the hot airflow.

[0060] In other embodiments, the portion of the second connector 142 facing the air outlet 22 can be designed to extend along an inclined straight line or curve, with its first end relatively close to the air outlet 22 and its second end relatively far away from the air outlet 22. As the first end points toward the second end, the second connector 142 gradually moves away from the air outlet 22. In this way, the distance between the second connector 142 and the air outlet 22 in the airflow direction x can be increased, thereby reducing temperature rise.

[0061] In some more specific embodiments, the second connecting member 142 is formed of a heat-resistant material and can withstand higher temperatures without deformation.

[0062] As shown in FIG7 , in some embodiments, the accessory 10 further includes a cover 15 having a first cover portion 151, a second cover portion 152, and a third cover portion 153. The first cover portion 151 covers the outer edge of the air inlet a, shielding the airflow portion 12 from infrared radiation; the second cover portion 152 spans the hollow portion c and forms the first connector 141; and the third cover portion 153 covers the end surface of the mounting portion 11 facing the drying device 20, shielding the mounting portion 11 from infrared radiation.

[0063] As shown in conjunction with Figures 1a, 1b, and 7, in some embodiments of the present application, the drying assembly 100 provides infrared radiation from the drying device 20, with a portion passing through the hollow portion c and the remaining portion irradiating the cover 15. The drying device 20 is equipped with optical structures such as reflective cups and condensers to limit the divergence angle and emission direction of the infrared radiation, thereby preventing the infrared radiation from irradiating areas other than the hollow portion c and the cover 15.

[0064] The material used for the cover 15 is different from the materials used for other parts of the accessory 10. In some embodiments, the cover 15 is made of a heat-resistant material that can withstand higher temperatures without deformation. In some embodiments, the cover 15 is made of a reflective material that can reflect most infrared radiation to reduce its own temperature rise. In some embodiments, the cover 15 is made of a metal material such as aluminum and steel that has both heat resistance and reflectivity. In some embodiments, the base material of the cover 15 is made of a heat-resistant material, and the surface of the base material is formed into a reflective surface through processes such as electroplating, thereby having both heat resistance and reflectivity.

[0065] As can be seen from the foregoing, accessory 10 is located near the end of drying apparatus 20, which is the area with the highest power density in the infrared radiation transmission path. Covering with cover 15 can enhance heat resistance or reflect infrared radiation, preventing local heating and deformation caused by infrared radiation.

[0066] It should be noted that heat-resistant and / or reflective materials generally have higher material costs and require special processing techniques. If the accessory 10 were entirely made of heat-resistant and / or reflective materials, this would result in increased costs. Therefore, using heat-resistant and / or reflective materials to form the cover 15, which forms the light-facing surface of the accessory 10, rather than the entire accessory 10, can reduce the cost of the accessory 10 while still meeting heat resistance requirements.

[0067] In some embodiments as shown in FIG4 , the mounting portion 11 of the accessory 10 is annular, and the airflow portion 12 is located within the annular portion of the mounting portion 11. The hollow portion c formed between the mounting portion 11 and the airflow portion 12 is annular or a portion thereof, corresponding to the shape of the radiation portion 21 of the drying device 20 or the light field formed by the infrared radiation.

[0068] Accordingly, as shown in FIG2 , the drying device 20 in some embodiments of the present application has a circular end, with an air outlet 22 formed in the central area of ​​the circle, and an annular radiation portion 21 formed around the outer edge of the air outlet 22. The radiation portion 21 can be formed by a single annular radiation source, or by a plurality of point radiation sources arranged along a ring. Since infrared radiation has good guidance, it is easy to achieve a smaller diffusion angle. Moreover, the airflow has poor guidance and will diffuse at a larger diffusion angle after being output from the air outlet 22. The radiation portion 21 on the end of the drying device 20 is arranged around the outside of the air outlet 22. In this way, after a preset transmission distance, the infrared radiation with a smaller diffusion angle and the airflow with a larger diffusion angle can form a roughly overlapping action area, and act together on the moisture in the area to achieve a drying process. Correspondingly, in the accessory 10 shown in FIG4 , a hollow portion c is formed on the outer edge of the airflow portion 12.

[0069] In some embodiments, as shown in FIG7 , the first covering portion 151 and the third covering portion 153 of the cover 15 are both annular, and the second covering portion 152 (first connector 141) radially connects the first covering portion 151 and the third covering portion 153. The second covering portion 152 connects the first covering portion 151 and the third covering portion 153 along the shortest path to minimize the heat transfer path within the cover 15. For related details, please refer to the previous description of the first connector 141.

[0070] In some embodiments as shown in FIG7 , a portion of the second covering portion 152 is curved along the airflow direction x to be as far away from the radiation portion 21 as possible, thereby reducing the temperature rise of the second covering portion 152 after receiving infrared radiation. For related content, please refer to the previous description of the first connecting member 141.

[0071] The cover 15 can be installed in a variety of ways. In some embodiments, the first cover portion 151 and the mounting portion 11 are secured to each other via snaps, screws, magnets, adhesives, or other methods, thereby securing the entire cover 15. In some embodiments, the third cover portion 153 and the airflow portion 12 are secured to each other via snaps, screws, magnets, adhesives, or other methods, thereby securing the entire cover 15.

[0072] In the specific embodiment shown in Figure 7, the second cover portion 152 forms an arched portion with a through-hole at the apex of the arch. Bolts (not shown) pass through the through-holes to secure the second cover portion 152 to the airflow portion 12. Because the arched apex is the point farthest from the cover 15 and the radiating portion 21, installing the bolts there minimizes the effects of infrared radiation on the bolts, thereby preventing gaps from forming between the bolts and the airflow portion 12 during repeated thermal expansion and cooling contraction. Furthermore, the arched apex is recessed relative to the overall accessory 10, concealing the bolts and minimizing their impact on the accessory 10's appearance.

[0073] In some embodiments shown in Figures 8 and 9, the airflow unit 12 includes an air inlet 122 and a diffuser 123. One end of the air inlet 122 forms an air inlet a. One end of the diffuser 123 is connected to the air inlet 122, and the other end forms an air outlet b. The air inlet 122 gradually decreases in size along the airflow direction x, while the diffuser 123 gradually increases in size in at least one direction along the airflow direction x.

[0074] After the airflow enters the air inlet portion 122 from the air inlet a, it is radially converged during the flow process and then enters the diffuser 123; when flowing along the diffuser 123, it diffuses in at least one direction and outputs the diffused airflow from the air outlet b.

[0075] As shown in Figure 9 , the air inlet portion 122 has its largest radial dimension near the air inlet a, the portion closest to the radiating portion 21, because its radial dimension tapers along the airflow direction x. The outer surface at the air inlet a blocks most infrared radiation, and only a small portion of the unblocked infrared radiation diffuses and impinges upon the outer surface of the airflow portion 12. The diffuser portion 123, located relatively far from areas with high infrared radiation power density, is less affected by infrared radiation. Therefore, for the entire airflow portion 12, simply enhancing the heat resistance near the air inlet a is sufficient to prevent the outer surface of the air inlet 122 from overheating due to infrared radiation. In some specific embodiments, as described above, the cover 15 is formed of a heat-resistant and / or reflective material, with the third cover portion 153 covering the air inlet a, thereby enhancing heat resistance and reducing the temperature rise there. In other specific embodiments, a reflective surface can be formed on the outer edge of the air inlet a through coating to reduce the infrared radiation absorbed by the air inlet a.

[0076] In certain embodiments, as shown in FIG. 1a or FIG. 1b and FIG. 4 , the accessory 10 further includes a sealing ring (not shown) provided at the air inlet a, and the sealing ring is used to form a seal between the edge of the air inlet a and the drying device 20. The sealing ring can ensure that all airflow output by the drying device 20 enters the interior of the airflow portion 12 and prevents the hot airflow from leaking to the outer surface of the airflow portion 12. If the hot airflow leaks, it will flow along the outer surface of the air inlet a, causing the hot airflow and infrared radiation to heat the outer surface of the air inlet a at the same time, and the problem of rapid overheating may occur. It can also be understood that when the accessory 10 is used in conjunction with the drying device 20, no airflow flows through the hollow portion c.

[0077] The first direction y and the second direction z are introduced below for the convenience of description. As shown in the various drawings of this application, the first direction y and the second direction z are perpendicular to each other, and the (y, z) plane is perpendicular to the airflow direction x. It should be noted that the airflow direction x shown in the various figures has positive and negative properties, and the positive direction points to the direction downstream of the airflow. The first direction y and the second direction z do not involve positive and negative properties. The arrows in the figures are only examples, and the positive and negative directions of the two are not distinguished below. In addition, the accessory 10 can be rotated at any angle relative to the drying device 20. The first direction y and the second direction z are directions determined based on the size of the accessory 10, and the first direction y and the second direction z have nothing to do with the drying device 20. For example, Figures 1a and 1b show two directions for installing the accessory 10. In other embodiments not shown above, the accessory 10 can also be installed on the drying device 20 in other directions.

[0078] As shown in Figure 8, the size of the diffusion part 123 gradually expands in the first direction y, and the first connecting member 141 also extends in the first direction y. Under the premise that the airflow needs to be directed to diffuse along the first direction y, the first connecting member 141 and the diffusion part 123 are set to roughly overlap in the projection in the direction of the airflow, so as to reduce the shielding of the infrared radiation by the accessory 10 and increase the transmittance of the infrared radiation. Moreover, the first connecting member 141 can also shield the diffusion part 123, reducing the temperature rise of the diffusion part 123 affected by infrared radiation. In some specific embodiments, as described above, in combination with Figure 7, the cover 15 is formed of heat-resistant and / or reflective material, and its second covering part 152 itself has heat resistance or can reflect infrared radiation, thereby reducing the temperature rise effect of infrared radiation on the diffusion part 123.

[0079] In some embodiments shown in Figures 4, 8, and 9, the guide member 13 is located on the axis of the airflow portion 12, forming an annular air inlet a between the guide member 13 and the airflow portion 12. When the airflow output from the drying device 20 flows through the guide cavity 121, the flow resistance is greater near the sidewalls of the guide cavity 121, while the flow resistance is lower at the axis, resulting in uneven radial airflow speed. The placement of the guide member 13 on the axis of the airflow portion 12 increases the flow resistance at the axis, achieving uniform radial airflow speed.

[0080] In some specific embodiments shown in FIG9 , along the airflow direction x, the size of the diffuser 123 in the second direction z remains substantially constant. For example, the diffuser 123 has the same size at all locations in the second direction z, or the size of the diffuser 123 at all locations in the second direction z varies by less than 20%, or the size of the diffuser 123 in the second direction z varies significantly less than the size in the first direction y.

[0081] When the airflow passes through the diffuser 123, it diffuses in the first direction y, while its dimensions in the second direction z remain roughly unchanged. Alternatively, the airflow is directed from a cylindrical shape to a flattened shape, with its dimensions in the first direction y significantly exceeding those in the second direction z. In Figure 6, the shape of the interior of the air outlet b represents the shape of the directed airflow. This flattened airflow is ideal for styling hair with a comb during hair drying. Furthermore, the flattened diffuser 123 has a smaller dimension in the second direction z, minimizing the shielding of infrared radiation by the entire accessory 10 in the second direction z.

[0082] According to fluid mechanics, when air flows through a cavity, the flow resistance is greater near the cavity's sidewalls, while the flow resistance is lower away from the cavity's sidewalls. If the cavity's radial dimensions are large, the flow velocity will vary significantly across the radial direction, affecting the overall smoothness of the airflow. To avoid this, in the embodiments of the present application, a flow guide 13 is provided within the airflow portion 12 to reduce the radial dimensions of the flow guide cavity 121 and prevent the formation of vortices.

[0083] Specifically, in some embodiments shown in Figures 8 to 11, the air guide 13 includes a first air guide portion 131 and a second air guide portion 132. The first air guide portion 131 is at least partially located in the air inlet portion 122, and its radial dimension gradually decreases along the airflow direction x. The second air guide portion 132 is at least partially located in the diffuser portion 123. The second air guide portion 132 divides the air guide cavity 121 into two parts.

[0084] As the airflow flows through the air inlet 122, it passes through the area between the outer surface of the first air guide 131 and the inner surface of the air inlet 122, forming an annular airflow that is guided and converged radially. Furthermore, the airflow is divided into two parts by the second air guide 132, further reducing the radial dimension of the airflow and ensuring uniform wind speed at all radial locations.

[0085] In some specific embodiments, the first guide portion 131 and the second guide portion 132 are integrally formed, which has lower manufacturing and assembly costs. In other embodiments, the first guide portion 131 and the second guide portion 132 can also be two independent structures, assembled to form the guide member 13 by bolts, gluing, snap fastening, etc.

[0086] In some specific embodiments shown in Figures 8 and 11 , a portion of the second flow guide portion 132 forms a second connector 142. As previously mentioned, the second connector 142 connects between the flow guide 13 and the airflow portion 12, thereby dividing the flow guide cavity 121 into two parts. In other words, the second connector 142 simultaneously secures the flow guide 13 within the flow guide cavity 121 and prevents eddy currents.

[0087] In some specific embodiments shown in Figures 9 to 11, the second guide portion 132 is plate-shaped, and the size of at least a portion of its area in the second direction z remains unchanged, which is adapted to the shape of the diffuser 123. The two together guide the airflow to diffuse along the first direction y.

[0088] In some specific embodiments shown in Figures 8 to 10, the first air guide portion 131 is conical, with its distal end extending to form a first tip pointing toward the air outlet b. The conical first air guide portion 131 matches the shape of the air inlet portion 122, and together they form an annular cavity with gradually decreasing radial dimensions, converging the airflow in the radial direction.

[0089] In some specific embodiments shown in Figures 8 and 11 , along the airflow direction x, the distal end of the second air guide 132 tapers in the first direction y, forming a second tip pointing toward the air outlet b; the diffuser 123 gradually expands in the first direction y. Because the diffuser 123 increases in size in the first direction y, vortices form when the airflow enters the diffuser 123 from the air inlet 122. The second air guide 132, which tapers in the first direction y, can mate with the second air guide 132, which expands in the first direction y, preventing vortices from forming during the airflow's diffusion in the first direction y.

[0090] In some specific embodiments shown in Figures 10 and 11 , the guide member 13 and the guide cavity 121 are both axisymmetric structures, sharing the same axis of symmetry. Furthermore, the ends of the first and second tips are both located on the axis of symmetry. This allows the guide cavity 121 to have uniform wind resistance at all radial locations, maintaining a uniform flow velocity at all locations while flowing through the guide cavity 121, and allowing air to be smoothly discharged from the air outlet b.

[0091] In some embodiments as shown in FIG8 , in the radial direction of the accessory 10, a portion of the outer edge of the second connecting member 142 is connected to the inner wall of the air inlet portion 122, while another portion extends into the diffuser 123. Along the airflow direction, one end of the outer edge of the second connecting member 142 is located at the air inlet a, and the other end is located at the diffuser 123.

[0092] After the airflow enters the air inlet a, it is guided by the first guide portion 131 and the second guide portion 132 at the same time, gradually shrinking in the radial direction and being divided into two parts, thereby changing the shape of the airflow while avoiding the formation of vortices.

[0093] As shown in Figures 8 and 11 , in some specific embodiments, the portion of the second connector 142 facing the air inlet a is designed to be curved and / or inclined, with its shape generally extending along its outer edge in a direction pointing toward the axis, gradually moving away from the air inlet a. Because the hot airflow output by the drying device 20 diffuses along its transmission path, gradually reducing its power density, the curved and / or inclined second connector 142 can increase the distance between the entire connector and the air inlet a while maintaining its original function, thereby reducing the temperature rise caused by the hot airflow.

[0094] In some embodiments of the accessory 10 shown in Figures 7 and 8 , the airflow portion 12 includes an outer wall 126 and an inner wall 124 adjacent to the air inlet a. The air inlet a is formed within the inner wall 124, and a heat-insulating cavity 125 is formed between the inner wall 124 and the outer wall 126. When the inner wall 124 of the airflow portion 12 is heated by the hot air flow, the heat-insulating cavity 125 prevents heat from being directly transferred from the inner wall 124 to the outer wall 126, thereby preventing burns to the user when contacting the outer surface of the accessory 10.

[0095] As shown in Figure 8, in some more specific embodiments, the size of the insulation cavity 125 gradually decreases along the airflow direction x. Because the hot air flow near the air inlet a is at its highest temperature, the insulation cavity 125 is at its largest location, providing optimal insulation. As the hot air flow gradually cools during its flow, the insulation cavity 125 also gradually decreases in size. This reduces the overall size of the accessory 10 while still meeting insulation requirements, improving ease of use.

[0096] As shown in FIG3 , in some specific embodiments, the outer wall 126 is connected to the mounting portion 11, forming a connection portion between the airflow portion 12 and the mounting portion 11. This can not only increase the mounting stability between the airflow portion 12 and the mounting portion 11, but also improve the appearance consistency of the accessory 10.

[0097] In the embodiment shown in Figures 4 and 5 , in the radial direction of the accessory 10, the extension direction of the first connector 141 coincides with the extension direction of the outer wall 126. The first connector 141 can shield the outer wall 126, preventing infrared radiation from reaching the outer wall 126 and the thermal insulation cavity 125, thereby increasing the transmittance of the infrared radiation and reducing the temperature rise of the outer wall 126.

[0098] In summary, the attachment 10 and drying assembly 100 provided in each embodiment of the present application include the attachment 10 having a generally flat airflow portion 12, capable of directing the airflow output by the drying device 10 into a flattened airflow. Furthermore, because the airflow portion 12 is significantly larger in the first direction y than in the second direction z, the attachment 10 only blocks infrared radiation in the first direction y. In the second direction z, a hollow portion c is formed between the airflow portion 12 and the mounting portion 10, allowing infrared radiation to pass through the exterior of the airflow portion 12.

[0099] As shown in Figure 5 , when viewing accessory 10 from the direction of air inlet a, it forms independent infrared radiation and airflow transmission paths, preventing localized overheating caused by both infrared radiation and thermal airflow. Furthermore, as shown in Figure 7 , a heat-resistant or infrared-reflective cover shields all light-facing surfaces of accessory 10, preventing deformation caused by overheating due to infrared radiation absorption.

[0100] 6 , when observing the attachment 10 from the air outlet b, it can output a flat airflow and a partially annular infrared radiation to the object to be dried, both of which act on the object to be dried simultaneously to provide a unique drying effect.
