Detailed Description

Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary only for the purpose of explaining the embodiments of the present application, and are not to be construed as limiting the embodiments of the present application.

As shown in fig. 1 to 14, in one embodiment of the present application, there is provided a radiation module 1, including a plurality of radiation sources 11 arranged according to a predetermined pattern, light emitting surfaces 121 of the plurality of radiation sources 11 are located on the same plane, and each radiation source 11 is capable of emitting infrared radiation of a predetermined wavelength band, the radiation sources 11 are configured to: the emergent light and the first axis L1 meet at a preset position a, and the first axis L1 may be located inside or outside the preset pattern.

The radiation source 11 is a device that emits Infrared (IR) radiation of a predetermined wavelength band, using the Infrared (IR) as a thermal energy source to remove water and moisture from an object (e.g., hair, fabric). Since different objects have different infrared radiation absorption rates for different wavelengths, it is possible to design the radiation source 11 to emit infrared energy having a predetermined wavelength band and power density to directly heat moisture of the object, rather than heat convection heating. The heat carried by the infrared energy is transferred directly to the moisture of the object in a radiative heat transfer manner, resulting in an increase in heat transfer efficiency as compared to conventional convective heat transfer manners (e.g., substantially no heat is absorbed by the surrounding air in a radiative heat transfer manner, whereas a significant portion of the heat is absorbed by the surrounding air and carried away in conventional conductive heat transfer manners). Another benefit of using infrared radiation as a source of thermal energy is that infrared heat can penetrate the hair shaft up to the cortex of the hair shaft, thus drying the hair faster and relaxing and softening the hair. Infrared energy is also thought to be beneficial to scalp health and to stimulate hair growth by increasing blood flow to the scalp. The use of an infrared radiation source also makes the drying apparatus compact and lightweight. The improved heat transfer efficiency and energy efficiency of the infrared radiation source may also extend the run time of the wireless drying apparatus powered by the embedded battery. Infrared radiation is essentially light, and the direction of the infrared radiation can be determined by the optical path arrangement so that it can be projected to a predetermined location.

As shown in fig. 1 to 6, the first axis L1 is not an actually existing structure, but a reference axis of the optical path design of the entire radiation module 1. In some embodiments shown in fig. 9, the first axis L1 is located on one side of all the radiation sources 11, i.e. the first axis L1 is located outside the predetermined pattern. In some embodiments shown in fig. 8, the first axis L1 may also be located between the plurality of radiation sources 11, i.e. corresponding to the first axis L1 being located inside the predetermined pattern. No matter what way the first axis L1 is set, after determining the position thereof, it is necessary to ensure that the emergent light of the plurality of radiation sources 11 and the first axis L1 intersect at the preset position a.

Drying apparatus 2, such as a hair dryer, hand dryer, or the like, capable of outputting an airflow, is capable of outputting an airflow at its body 21 that follows a substantially linear airflow path, as is well known in the art. The radiation component 1 in the embodiment is applied to the drying equipment 2, the first axis L1 of the radiation component 1 is overlapped with the airflow path of the drying equipment 2, so that the emergent light of the radiation source 11 can be guided and converged at the preset position a of the airflow path, the infrared radiation effect caused by the airflow and the converged infrared radiation can be ensured at the position, and the evaporation of water from an object is further accelerated by combining the airflow and the converged infrared radiation.

In other words, although the radiation source 11 assembly in the above embodiment does not include the air duct, the first axis L1 is a reference axis of the infrared radiation to simulate an air flow path through which air is blown out from the air duct, and hereinafter, the first axis L1 may also be understood as an air flow path unless otherwise specified.

When a user uses the drying device 2 with the radiation assembly 1, a target object to be dried, such as wet hair, fabric and the like, is placed at the preset position a, infrared radiation is converged at the preset position a, heat is transferred to moisture, the moisture is heated and evaporated, and the target object can be cooled while the evaporation is promoted by airflow flowing through the preset position a, so that the danger of rapid heating due to convergence of the infrared radiation is avoided.

In a specific application scene, it sets up to predetermineeing position a and sets up to approximately 10CM department apart from 2 air outlets 211 of drying equipment, the user is using drying equipment 2, put drying equipment 2's air outlet 211 when apart from target object 10CM, can dry the target object simultaneously through air current and infrared radiation, after dry later stage moisture reduces gradually, do not have the heat of the infrared radiation transmission that enough moisture absorption assembles, make target object itself also begin to absorb infrared radiation and heat up, dispel the heat because being acted on by the air current simultaneously this moment, can avoid the high temperature danger that the target object intensifies and lead to. Therefore, the radiation source 11 of sufficient power can be used to avoid rapid temperature rise of the target while achieving rapid drying of the target.

The light emitting surfaces 121 of the plurality of radiation sources 11 in the radiation component 1 are arranged on the same plane, so that the light emitting surfaces can be coplanar with the air outlet 211 of the drying device 2, and the design of consistency of product appearance is facilitated. In terms of aerodynamics, the airflow at the air outlet 211 of the drying device 2 flows outward rapidly, negative pressure is formed near the air outlet 211, and the air around the outside of the air outlet 211 is absorbed and merged into the airflow, and if a non-planar structure, such as a plurality of non-coplanar planar structures, edges, grooves, etc., exists near the air outlet 211, the flowing airflow is disturbed, a turbulent flow or a vortex flow is formed, which not only generates noise, but also leads to airflow disturbance after the airflow is merged into, and influences the collimation and the stability of the airflow output by the drying device 2. The light emitting surfaces 121 of the plurality of radiation sources 11 in this embodiment are located on the same plane, and the air flow passing through any radiation source 11 does not form a turbulent flow or a vortex, which has little influence on the final output air flow, and is beneficial to optimizing the pneumatic performance of the drying device 2, so that the drying device 2 has better product force.

In some embodiments, the light emitting surface 121 of each radiation source 11 is located on a normal plane of the first axis L1, in other words, the first axis L1 is perpendicular to the light emitting surface 121 of each radiation source 11, so that when the drying apparatus 2 is applied, the blown air flow direction is perpendicular to the light emitting surface 121 of each radiation source 11, that is, has the same included angle, so that the air flow flowing through each light emitting surface 121 has better consistency, and the influence on the air flow output by the drying apparatus 2 is further reduced.

The radiation source 11 can converge the outgoing light onto the first axis L1 in various ways, as shown in fig. 2 to 4, in some embodiments, the converging can be realized by using an optical element 14, and the optical element 14 is disposed on the outgoing surface 121 of the radiation source 11, and can guide the infrared radiation of the radiation source 11 to the outgoing light propagating along a preset angle.

The optical element 14 is a structure capable of changing infrared radiation, and can guide and emit incident light rays in a preset direction through the arrangement of shape and material. According to the relative position relationship between the preset position a on the first axis L1 and each radiation source 11, the deflection angle of the light emitted by the radiation source 11 can be determined, and the optical performance of the optical element 14 is set with the angle as the preset angle, so that the infrared radiation emitted by the radiation source 11 can be converged on the preset position a on the first axis L1 after passing through the optical element 14. For example, if there are two radiation sources 11 symmetrically disposed with respect to the first axis L1, the outgoing light from the two radiation sources has symmetrical deflection directions, and the respective requirements for the optical element 14 are different.

In some embodiments, as shown in fig. 2 and 4, the portion of the optical element 14 located on the light emitting surface 121 is configured to: the thickness of the optical element 14 increases along the direction pointing to the first axis L1 to form a gradually thickened shape, which enables the infrared radiation deflection angle on the light emitting surface 121 farther from the first axis L1 to be larger, and the infrared radiation deflection angle closer to the first axis L1 to be smaller, so that the emergent light on the light emitting surface 121 is guided to the preset position a of the first axis L1 to form convergence.

In some embodiments, the optical element 14 can cover the light exit surfaces 121 of the plurality of radiation sources 11. Since the position of the radiation source 11 relative to the first axis L1 is different, the optical element 14 is required to be specially designed according to the position relative to the first axis L1 corresponding to the different positions of the radiation source 11. In addition, the light emitting surfaces 121 of the plurality of radiation sources 11 are coplanar, the inner surface of the optical element 14 can be set to be a plane, and the outer surface of the optical element 14 can be set to be an inclined surface or a spherical surface, so that the optical element 14 can be simultaneously covered on the light emitting surfaces 121 of all the radiation sources 11, and the product has better appearance consistency and high integration level.

For example, in the embodiment shown in fig. 2, 3, 8, and 10, the predetermined pattern of the arrangement of the radiation sources 11 is a ring shape, in this embodiment, the first axis L1 is disposed at a center portion of the ring shape, so that a plurality of radiation sources 11 can be formed to surround the first axis L1, and in practical applications, light is emitted from the circumferential direction of the air outlet 211 of the drying device 2 and converged. In this embodiment, the ring-shaped optical element 14 can be used to cover the light exit surfaces 121 of all the radiation sources 11 at the same time, and to achieve the guiding effect on the infrared radiation. As shown in fig. 2 and 3, since the first axis L1 is a predetermined airflow path and a space for air to flow through is required to be reserved at the first axis L1, the optical element 14 is substantially annular, and an area of the annular shape near the middle is thicker, and an outer edge of the annular shape is thinner, which is equivalent to a convex lens with a through hole in the middle. It is easy to understand that the light-emitting surface of the convex lens is a spherical surface, and the optical element 14 in the present application, as shown in fig. 2 and fig. 4, may be a spherical surface or an inclined surface, and the specific shape is not limited, and the above-mentioned deflection effect can be achieved.

Other embodiments of the optical element 14 that vary the light transmission may be used, such as multiple layers of materials with different transmittances, coatings on the lens, other light deflecting structures known to the public in the art, or combinations thereof, where different structures are provided at different locations to accommodate the desired predetermined angle of the emitted light.

In some embodiments, there may be a plurality of optical elements 14, and the optical elements 14 correspond to the radiation sources 11 one by one, and each optical element 14 deflects and guides the infrared radiation of one radiation source 11. Depending on the position of the radiation source 11 relative to the first axis L1, different configurations of the optical elements 14 may be provided, or optical elements 14 of the same configuration may be rotated by a corresponding angle as needed to meet the infrared radiation deflection requirements of the radiation source 11. It is easy to understand that the graph of the optical element 14 in the drawings is only shown in the drawings and does not represent the actual shape, and even if a spherical surface or an inclined surface is used as the light emitting surface, the difference in the influence on the flowing air flow is very small compared with a plane surface, and the problem of air flow turbulence is not caused.

In some embodiments, the predetermined pattern of the plurality of radiation sources 11 may also be a portion of a ring, i.e. the plurality of radiation sources 11 semi-surrounds the first axis L1, and accordingly, the optical element 14 may also be correspondingly shaped. It will be readily appreciated that when the plurality of radiation sources 11 are arranged in a ring or a portion of a ring, the first axis L1 may not be inside the ring or may be outside the ring, such that the plurality of radiation sources 11 are arranged in a side-by-side relationship with the first axis L1 and the gas flow passes from one side of the plurality of radiation sources 11. The plurality of radiation sources 11 shown in fig. 11 are each located on one side of one axis L1, and a part thereof is arranged as a part of a ring shape, half surrounding the first axis L1. The plurality of radiation sources 11 may also be arranged in other regular or irregular shapes, or in a matrix or other shape in an array, and the first axis L1 can also be arranged inside or outside the preset shape of the array, and the light path scheme is similar to the aforementioned circular arrangement. In fig. 9, a scheme is shown in which a plurality of radiation sources 11 are arranged in a matrix in an array shape, and a first axis L1 is located outside the matrix pattern, which corresponds to the plurality of radiation sources 11 being juxtaposed to the first axis L1. The relationship between the preset patterns arranged on the first axis L1 and the plurality of radiation sources 11 is related to the directions of the respective emergent lights of the radiation sources 11, but is not necessarily related to the technical scheme for realizing the convergence of the emergent lights, and other schemes for realizing the convergence of infrared radiation are related to the relationship below, so that the influence relationship of the preset patterns arranged on the first axis L1 and the radiation sources 11 on the convergence of the emergent lights is not repeated.

In the optical system designed by means of the optical element 14, there is no special requirement for the radiation source 11 itself, and the radiation source 11 may be a separate light emitting element 13, such as a bulb, an LED, etc., or a light source with a reflector cup 12, such as a halogen lamp, etc., arranged in the reflector cup 12.

In addition to the arrangement of optical element 14 outside radiation source 11, it is also possible to realize radiation source 11 emitting light at a predetermined angle by means of a specially arranged reflector cup 12.

As shown in fig. 1 and 5, in some embodiments, the radiation source 11 includes a reflective cup 12 and a light emitting element 13 disposed in the reflective cup 12, the reflective cup 12 has a structure with a concave surface (such as a paraboloid, a sphere, a polynomial curve forming plane, etc.) inside, and can converge and rectify light emitted by the light emitting element 13 disposed inside into parallel light to be emitted, and a central axis of the emitted light is referred to as an optical axis L2 of the reflective cup 12 and is generally a straight line where an opening center of the reflective cup 12 and a focal point connecting line are located.

The optical axis L2 of the reflector cup 12 and the first axis L1 intersect at the preset position a, which is equivalent to that each reflector cup 12 inclines integrally toward the direction of the first axis L1, and the parallel light (emergent light) emitted after rectification points to the preset position a of the first axis L1, thereby realizing convergence of infrared radiation. Further, the open end of the reflector cup 12 is disposed on a normal plane located on the first axis L1. In the prior art, the plane where the opening of the reflective cup 12 is located is perpendicular to the optical axis L2 thereof, but in the present embodiment, it is equivalent to shape a part (the part of the dashed frame shown in fig. 5) of the cut opening of the reflective cup 12, so that the plane where the opening is located (i.e., the light emitting surface 121) and the optical axis L2 are inclined, thereby achieving both the convergence of the infrared radiation by the plurality of radiation sources 11 and the coplanarity of the light emitting surfaces 121 of the plurality of radiation sources 11.

It will be readily appreciated that the inclination and angle of the reflector cups 12 of the radiation source 11 at different relative positions of the first axis L1 will also be different, so as to ensure that the optical axis L2 of each reflector cup 12 points to the predetermined position a. Accordingly, the cutting and shaping portions at the opening of the reflector cup 12 are different.

When the radiation assembly 1 adopting the reflecting cup 12 is applied to the drying device 2, the reflecting cup 12 is inclined towards the airflow path and can emit infrared radiation pointing to the airflow path, so that the airflow and the radiation can be converged and act on the same part of a target object.

In some other embodiments, as shown in fig. 6, the reflector cup 12 and the luminescent element 13 of the radiation source 11 may be arranged in another way: the light emitting member 13 disposed in the reflector cup 12 is offset from the focal point of the reflector cup 12 and is located on a side away from the first axis L1. The optical system of the reflector cup 12 is generally designed such that, when the luminous element 13 is at its focal point, the infrared radiation emitted by the luminous element 13 is rectified to be parallel to the optical axis L2 and thus emitted. When the light emitting element 13 deviates from the focus, the radiation rectified by the reflective cup 12 is emitted in the direction deviating from the optical axis L2, which is a negative condition that needs to be avoided in the optical system in the prior art, but the present embodiment has a positive technical effect that the emitted light of the radiation source 11 is deflected and emitted in the direction facing the first axis L1, and the emitted light of the plurality of radiation sources 11 can be converged at the preset position a.

The radiation source 11 of the off-focus point type is adopted, and the reflecting cup 12 itself does not need to be inclined towards the first axis L1, and can be oriented towards other directions without being limited by the first axis L1. In a preferred embodiment, the optical axis L2 of the reflective cup 12 is parallel to the first axis L1, so that the opening of the reflective cup 12 is not cut and shaped, and the light emitting surface 121 itself is located on the normal plane of the first axis L1, so that the light emitting surfaces 121 of the reflective cups 12 are easily coplanar with each other.

The position and direction of the light-emitting element 13 away from the focal point also need to be specially designed to meet the requirements of the optical system. Generally, the reflector 12 has a focal plane inside, i.e., a plane passing through the focal point and perpendicular to the optical axis L2. Since the light emitting element 13 is not an ideal point light source but has a certain spatial structure in the actual design process, such as a spiral filament of a tungsten halogen lamp, a chip of an LED light source, etc., the optical system is generally designed to have a certain tolerance, so that when the design position of the light emitting element 13 is approximately located on the focal plane, the requirement that the light emitted by the light emitting element 13 is rectified by the optical system can be satisfied. In other words, for the optical system, the light emitting element 13 is disposed away from the focal plane, which results in most of the light not being rectified by the optical system in a predetermined manner, and therefore, in a preferred embodiment, the light emitting element 13 is still located on the focal plane although it is away from the focal point, so as to maintain a high light rectification efficiency of the light reflecting cup 12, thereby preventing insufficient light from finally converging to the predetermined position a. Therefore, the aforementioned solution that the optical axis L2 of the reflective cup 12 is parallel to the first axis L1 can be combined, in this solution, the focal plane is also located on a normal plane of the first axis L1, and both the focal point and the light emitting element 13 are located on this plane, so that the position design requirement for the light source in the optical system can be satisfied.

It will be readily understood that the various optical path systems formed by the optical element 14 or the reflector cup 12 are not mutually contradictory, and that multiple optical path systems may be used to focus infrared radiation, for example, the reflector cup 12 and the optical element 14 may be tilted simultaneously. In the following, the drying apparatus 2 and the reflector base 5 are disclosed to include the above-mentioned light path design, which can be understood by referring to the above.

As shown in fig. 1, some embodiments of the present application also provide a drying apparatus 2, which includes a housing 21, a motor 3, a radiation assembly 1 and a power supply module (not shown). An air duct is provided in the housing 21, and the motor 3 is located in the housing 21 and is capable of generating an air flow in the air duct that propagates along the first axis L1. Radiation module 1 includes at least one radiation source 11 that can be used for producing infrared radiation, and the power module supplies power to radiation module 1 at least, through the output who adjusts power module, can adjust the wave band of radiation source 11, makes it send the infrared radiation of predetermineeing the wave band. The exit light of the radiation source 11 and the first axis L1 meet at the preset position a.

In the drying apparatus 2 of the present embodiment, the motor 3 outputs the airflow propagating along the first axis L1, and the outgoing light from the radiation source 11 is guided and converged at the preset position a of the airflow path (i.e., the first axis L1), where convergence of the airflow and the radiation of the infrared radiation can be ensured. When the user uses drying equipment 2, will need dry target object, for example moist hair, fabric etc. to place in this preset position a, infrared radiation assembles transfer heat to moisture, makes moisture evaporation of being heated, and the air current also cools down the target object when promoting the evaporation to avoid the danger of leading to rapid heating up because of infrared radiation assembles.

For example, set up preset position a to be apart from 2 air outlets 211 of drying equipment and locate roughly 10CM, the user is when using drying equipment 2, when distance target object 10CM, can dry the target object simultaneously through air current and infrared radiation, after dry later stage moisture reduces gradually, do not have sufficient moisture to absorb the heat of the infrared radiation transmission that assembles for target object itself also begins to absorb infrared radiation and intensifies temperature, dispel the heat because by the air current effect simultaneously this moment, can avoid the danger that target object intensifies and leads to rapid heating up. Therefore, the radiation source 11 with sufficient power can be used to avoid the rapid temperature rise of the target object on the premise of realizing the rapid drying of the target object, so that the drying device 2 has better product strength.

For the above-mentioned drying apparatus 2, it is able to set various arrangements of the radiation sources 11 according to the requirement, for example, in one embodiment shown in fig. 1 and 8, the radiation sources 11 are set around the air duct, so as to realize light emission and convergence along the circumferential direction of the air flow path, and the air outlet 211 is easy to design to be circular, which is easy to maintain better pneumatic performance. Further, the plurality of radiation sources 11 may be uniformly distributed along the circumferential direction of the wind tunnel, so that the radiation intensity at each position of the light spots formed by convergence on the target is substantially the same. In another embodiment, as shown in fig. 7 and 9, a wind tunnel and the radiation sources 11 may be arranged in parallel, such that one or more radiation sources 11 are arranged on one side of the first axis L1, the design of the optical system is easier, and on the premise of the same cross-sectional area, radiation sources 11 with larger size can be used, for example, one radiation source 11 with larger size is used to replace a plurality of radiation sources 11 with smaller size, so as to reduce the design complexity of the wind tunnel and the light path.

The airflow at the air outlet 211 of the drying apparatus 2 flows outward rapidly, negative pressure is formed near the air outlet 211, and the air outside the air outlet 211 is absorbed and merged into the airflow, and if a non-planar structure, such as a plurality of non-coplanar planar structures, edges, grooves, etc., exists near the air outlet 211, the airflow passing through the structures is disturbed, a turbulent flow or a vortex is formed, which not only generates noise, but also leads to airflow disturbance after the airflow is merged into the airflow, and affects the collimation and the stability of the airflow output by the drying apparatus 2. And if set up radiation component 1 in the position of keeping away from air outlet 211, can lead to relevant structures such as casing 21 of air outlet 211 again to shelter from infrared radiation for infrared radiation can only assemble to farther position, must also be far away from the target object when using drying equipment 2, causes the user to use the puzzlement. For the above reasons, it is necessary to dispose the light exit surface 121 of the radiation source 11 close to the air outlet 211 and avoid affecting the air flow. Therefore, the light emitting surfaces 121 of the plurality of radiation sources 11 are arranged on the same plane, and are arranged near the air outlet 211 or are coplanar with the air outlet 211, so that the airflow flowing through the light emitting surfaces 121 of any radiation sources 11 cannot form turbulent flow or vortex flow, the influence on the finally output airflow of the drying equipment 2 is small, the pneumatic performance of the drying equipment 2 is favorably optimized, and the drying equipment 2 has better product force. Moreover, the plurality of radiation sources 11 coplanar with the air outlet 211 of the drying device 2 also facilitate the design of consistency of the product shape.

In some further embodiments, the light emitting surface 121 of the radiation source 11 is located on a normal plane of the first axis L1, that is, the direction of the air flow output from the drying apparatus is perpendicular to the light emitting surface 121 of the radiation source 11, and the direction of the blown air flow is perpendicular to the light emitting surface 121 of each radiation source 11, that is, has the same included angle, so that the air flow flowing through each light emitting surface 121 has better consistency, and the influence on the air flow output by the drying apparatus 2 is further reduced.

In some embodiments, the drying apparatus 2 further comprises one or more optical elements 14, the optical elements 14 being mounted to the one or more radiation sources 11 and being capable of directing the light emitted by the light emitting member 13 as outgoing light propagating along a predetermined angle. With respect to the optical path of the radiation module 1, the optical element 14 acts to refract and converge the light, and the specific structure and related principles that can be used can be described with reference to the foregoing related contents, and will not be repeated here. In the case of the drying device 2, the optical element 14 covers the light exit face 121 of the radiation source 11, and in addition to the refraction effect on the infrared radiation of the radiation source 11, the optical element 14 actually forms a plane through which the air sucked by the influence of the output air flow flows, and the optical element 14 itself is a smooth structure and can also play the aforementioned role of avoiding air flow turbulence, eddy currents and the like. The optical element 14 may be a one-piece lens structure covering all or part of the radiation source 11 or may be a plurality of individual lens structures each covering a radiation source 11.

It will be readily appreciated that in some embodiments the radiation assembly 1 in the drying apparatus may focus the infrared radiation through the optical element 14, but in other embodiments the optical element 14 may also focus the light by other configurations of the radiation source 11, such as the reflector cup 12 described above and below, without refracting the infrared radiation. When the optical element 14 is a planar lens, it does not focus infrared radiation, but exists only as a structure covering the open end of the reflector cup 12. The effect of the optical element 14 on the infrared radiation is not limited to refraction of the infrared radiation, and filtering or presenting a preset color in a spectrum can be achieved by changing transmittance of light with different wavelengths, and certainly, the effects of infrared radiation convergence, filtering, color presenting and the like can also be simultaneously achieved.

In some embodiments, as shown in fig. 1 and 14, the housing 21 of the drying device 2 has an opening at an end facing the target, a partial area of the opening is covered by the optical element 14, and another partial area of the opening is at least partially connected to the air duct and constitutes the air outlet 211. That is, the opening of drying equipment 2 is divided into two main regions, and one region is a light-emitting region, can outwards radiate infrared radiation, and another region is a wind-out region, is connected to inside wind channel and outwards exports the air current. It will be readily appreciated that in practice, there may be regions where neither light nor air is emitted at the end of the housing 21 facing the object for the purpose of fitting the relevant components.

In a more specific embodiment, as shown in fig. 14, the opening of the housing 21 has a circular cross section, a circular air outlet 211 is opened at the middle part, and the optical element 14 disposed around the air outlet 211 in a ring shape covers the other area of the opening and shields all the radiation sources 11. It can be understood that, at the opening of the housing 21, in addition to the area of the outlet air, there is also an area emitting infrared radiation, i.e. by means of the annular optical element 14, which has the effect of planning the outlet air opening 211 and covering the opening of the housing 21. In other embodiments, the cross-section of the opening may be rectangular, triangular, oval, or a combination thereof. The optical element 14 may also be arranged in parallel with the air outlet 211, for example, as shown in fig. 7, the air outlet 211 is arranged at the lower part of the opening, and the radiation source 11 and the optical element (not shown) are arranged at the upper part. The optical element 14 may also be semi-enclosed, partially annular, or a combination thereof.

In some embodiments, the radiation assembly 1 is located outside the air duct, i.e. the air flow does not substantially flow through the radiation assembly 1, so that the interference of the radiation assembly 1 on the air flow can be avoided, and a smooth air duct is formed in the drying device 2. In other embodiments, a part of the radiation module 1 may be disposed in the air duct, or the radiation source 11 may form a part of a side wall of the air duct, so as to dissipate heat of the radiation module 1 by means of the air flow in the air duct.

In the drying apparatus 2 of the embodiment of the present application, the optical path system thereof can be referred to fig. 2 to 6, and one or more of the following manners are adopted:

(1) The focusing of the infrared radiation to the radiation source 11 is achieved by means of an optical element 14, at least the part of the optical element 14 located at the radiation source 11 increasing in thickness in a direction pointing towards the first axis L1.

(2) The radiation source 11 comprises a luminescent element 13 and a reflector cup 12, and an optical axis L2 of the reflector cup 12 and the first axis L1 intersect at a predetermined position a.

(3) The radiation source 11 comprises a luminous element 13 and a reflecting cup 12; the light emitting member 13 is offset from the focal point of the reflective cup 12 and located on a side away from the first axis L1. Optionally, the optical axis L2 of the reflector cup 12 is parallel to the first axis L1. Alternatively, the light emitting element 13 and the focal point are located on the same normal plane of the first axis L1, i.e. the light emitting element 13 is located on the focal plane.

The principle and process of light collection in each optical system are described in detail in the foregoing description of the radiation module 1, and are not repeated.

As shown in fig. 1 to 14, a reflector base 5 is also provided in some embodiments of the present application, and is also applied to the drying apparatus 2.

A part of the reflector 5 is provided with a through cavity 51 for air flow to pass through, or a part of the reflector 5 forms a part of the through cavity 51; another part of the reflector base 5 is provided with one or more reflector cups 12, the reflector cups 12 having mounting locations 122. The through cavity 51 extends along the first axis L1, and when the light emitting member 13 is mounted on the mounting position 122, the reflective cup 12 rectifies the infrared radiation emitted by the light emitting member 13 so that the emergent light and the first axis L1 meet at a predetermined position a. In other words, after the light emitting element 13 is mounted to the mounting position 122 on the reflector 5 and the power is supplied to the light emitting element 13, the emitted infrared radiation is converged at the predetermined position a of the first axis L1.

In some embodiments, as shown in fig. 11 to 13, a portion of the reflector base 5 is opened with a complete through cavity 51, that is, the reflector base 5 itself constitutes a portion of the air duct for air flow to pass through. In other embodiments, which are not shown, a portion of each reflector base 5 forms a portion of the through-cavity, and a plurality of reflector bases 5 or reflector bases 5 and other structures, such as a housing, a cylindrical tube, an optical element 14, a flow guide, and the like, together enclose the through-cavity as a portion of an air duct for passing an air flow. The first axis L1, i.e. the axial direction in which the through cavity 51 extends, also substantially forms an airflow path extending along the first axis L1 when the airflow is output along the through cavity 51, thereby achieving convergence of the airflow and the infrared radiation at the preset position a. When the user uses drying equipment 2, will need dry target object, for example moist hair, fabric etc. to place in this preset position a, infrared radiation assembles transfer heat to moisture, makes moisture evaporation of being heated, and the air current also cools down the target object when promoting the evaporation to avoid the danger of leading to rapid heating up because of infrared radiation assembles. Therefore, the radiation source 11 with sufficient power can be adopted, and the target object is prevented from being heated rapidly on the premise of realizing rapid drying of the target object, so that the drying device 2 adopting the reflector base 5 has better product force.

In some embodiments, as shown in fig. 12 and 13, the number of the reflective cups 12 is multiple, and the light emitting surfaces 121 of the multiple reflective cups 12 are on the same plane. In the process that the airflow flows out of the light reflecting seat 5 through the through cavity 51, negative pressure is formed near the air outlet 211, so that the air outside the air outlet 211 is absorbed and merged into the airflow, and if a non-planar structure, such as a plurality of non-coplanar planar structures, edges, grooves and the like, exists near the air outlet 211, airflow flowing through the structures is disturbed, a turbulent flow or a vortex flow is formed, so that not only noise is generated, but also the airflow is disturbed after being merged into the airflow, and the collimation and the stability of the airflow output by the drying device 2 are affected. Therefore, the light emitting surfaces 121 of the plurality of radiation sources 11 are located on the same plane, and the air flow passing through the light emitting surface 121 of any radiation source 11 does not form turbulent flow or vortex flow, so that the influence on the air flow flowing out of the reflection seat 5 is small, the pneumatic performance is favorably optimized, and the drying device 2 has better product force.

In some further embodiments, the light emitting surface 121 of the reflective cup 12 is located on a normal plane of the first axis L1, that is, the direction of the air flow output from the drying device is perpendicular to the light emitting surfaces 121 of the radiation sources 11, and the direction of the air flow blown out from the drying device is perpendicular to the light emitting surfaces 121 of the radiation sources 11, that is, the air flow has the same included angle, so that the air flow flowing through the light emitting surfaces 121 has better consistency, and the influence on the air flow output from the drying device 2 is further reduced.

In a specific embodiment, as shown in fig. 12 and 13, the reflector base 5 has an end surface 52 perpendicular to the first axis L1, one end of the through cavity 51 is connected to the end surface 52 to form the actual air outlet 211, and the open end of each reflector cup 12 is located on the end surface 52, so that the openings (i.e., the light emitting surfaces) of the reflector cups 12 are all located on the same plane. Furthermore, the entire optical element 14 can be directly provided on the end surface 52 of the reflector base 5 to cover each reflector cup 12, thereby covering the light exit area, but it is also possible to cover each reflector cup 12 with a plurality of optical elements 14, respectively

For example, as shown in fig. 12 to 14, the reflector base 5 is annular, the middle portion of the reflector base is provided with a complete through cavity 51, a plurality of reflector bases 5 are arranged around the through cavity 51, and at this time, the optical element 14 is correspondingly annular, so that the optical element can cover each reflector base 5 and simultaneously supply air flow to the hollow area. Alternatively, the reflector bases 5 may be a part of a ring, the plurality of reflector bases 5 may be combined to form a ring as a whole, and form a complete through cavity 51, and the reflector cups 12 on the reflector bases 5 may be arranged around the first axis L1 according to the part of the ring.

In other embodiments, the plurality of reflective cups 12 may be arranged in other predetermined patterns, such as an array matrix, a triangle, a hexagon, etc. The relationship between the preset pattern formed by arranging the plurality of light-reflecting cups 12 and the first axis L1 may be that the first axis L1 is located inside the preset pattern, that is, the plurality of light-reflecting cups 12 are arranged around the first axis L1 (see fig. 10), or that the first axis L1 is located outside the preset pattern, and the plurality of light-reflecting cups 12 are arranged in parallel on the same side of the first axis L1 (see fig. 11).

In the reflective base 5 of the present embodiment, the optical path system may adopt one of the following modes, or a combination of the following modes:

(1) The optical axis L2 of the reflector 12 and the first axis L1 intersect at the predetermined position a.

(2) The light emitting element 13 at the mounting position 122 is offset from the focal point of the reflector cup 12 and is located on the side away from the first shaft axis. Optionally, the optical axis L2 of the reflector cup 12 is parallel to the first axis L1. Optionally, the light emitting element 13 and the focus on the mounting position 122 are located on the same normal plane of the first axis L1. It is easily understood that, in this embodiment, the mounting position 122 needs to ensure that the light emitting element 13 mounted thereon deviates from the focal point of the reflective cup 12, and the light emitting element 13 itself may have a certain shape and mounting size, so that, depending on the actual shape and mounting size of the light emitting element 13, the mounting position 122 may have the light emitting element 13 mounted thereon deviating from the focal point although it is set at the focal point, or the mounting position 122 itself deviates from the focal point and causes the light emitting element 13 to deviate from the focal point.

In summary, the radiation assembly, the drying device and the reflector base provided in the embodiments of the present application have at least the following main technical effects:

(1) With the infrared radiation that radiation source 11 sent to predetermineeing position a on the air current route, can ensure to have air current and infrared radiation's effect simultaneously when carrying out the drying to the target object, when the two combines to improve drying efficiency, the air current plays the heat dissipation effect to the target object, can avoid infrared radiation to assemble and lead to the danger that rapid heating up brought.

(2) The radiation sources 11 are optimally designed, so that the respective light emitting surfaces 121 are on the same plane, can be arranged near the air outlet of the drying equipment 2, and have small influence on the output airflow, thereby ensuring that the drying equipment 2 has better pneumatic performance and optical performance, being beneficial to the design of product appearance consistency and ensuring that the drying equipment 2 has higher product strength.

(3) By adopting the design that the plurality of radiation sources 11 emit infrared radiation and then converge at the preset position a, the total radiation power can be dispersed to each radiation source 11 on the premise of ensuring that the preset position a has enough total radiation power. The infrared radiation of the plurality of radiation sources 11 can not be converged at any position except the preset position a, the danger of rapid temperature rise can be avoided even if no airflow flows through, and the drying device has high drying efficiency and safety.
