As shown in fig. 2, the air passage is a passage through which the air current flows, that is, the fan unit 16 guides the air current to flow through the air passage and discharge the air current to the outside of the hair dryer through the air outlet 101, but the present embodiment does not limit the arrangement position of the air inlet, as long as the air passage can be formed between the air inlet and the air outlet 101, that is, the air inlet can be opened at any position of the hair dryer, for example: a handle or a wind barrel body.

As shown in fig. 2 and 4, the air passage includes at least one tapered section, so that when the air flow passes through the tapered section, the air flow is compressed, and when the air flow passes through the tapered section, the compressed air flow is instantaneously diffused, so that the air speed and the air pressure of the air flow blown by the hair dryer are higher, and the hair drying efficiency is higher, that is, the common motor 17 can also realize the hair dryer with higher air pressure and air speed, specifically, the number of the tapered sections is not limited in the air passage in this example, that the air passage can have one tapered section, or a plurality of tapered sections can be provided, and when one tapered section is provided, the tapered section extends from the inside of the housing 1 to the air outlet 101, that is, the starting end of the tapered section is far away from the position where the air outlet 101 is provided inside the housing 1, and the ending end of the tapered section is near the air outlet 101, the sectional area of the starting end of the conical section is larger than that of the ending end of the conical section, so that the conical section has the tendency of contracting towards the air outlet 101, and the air flow flowing out of the conical section is compressed and then is blown out of the blower through the air outlet 101; when there are a plurality of tapered sections, the present example does not limit the positional relationship between the plurality of tapered sections, that is, the plurality of tapered sections may be sequentially horizontally disposed in the air passage, and the plurality of tapered sections may also be disposed side by side in the air passage, but the cross-sectional area of the starting end of one or more tapered sections connected to the air outlet 101 is larger than the cross-sectional area of the terminating end of the tapered section, so that the air flow finally flowing out of the air outlet 101 is compressed.

As shown in fig. 2, an inner wall 111 is disposed in the housing 1 for guiding the airflow in the air passage, the air passage is formed between the inner wall 111 and the housing 1, the inner wall 111 is flared near the air outlet 101, specifically, the inner wall 111 is flared near the air outlet 101, so that the space defined between the inner wall 111 and the housing 1 is contracted towards the air outlet 101, the airflow is compressed when flowing through the space, and the compressed airflow is instantaneously diffused when blowing out of the conical section, so that the wind speed and the wind pressure of the airflow blown out by the hair dryer are higher, and the hair drying efficiency is higher, in this case, the cross-sectional shape of the air passage is made to be a substantially trapezoidal structure, that is, the downstream end of the air corresponds to the short side of the trapezoid, the upstream end of the air corresponds to the long side of the trapezoid, and the sides between the long side and the short side are non-parallel, meanwhile, the side edge can be a straight line or a curve, and because the inner wall 111 is trumpet-shaped, a conical section can be formed when the shell is cylindrical, so that the appearance of the hair dryer is more attractive.

As shown in fig. 2, wherein a heater is further disposed in the air passage, the inner wall 111 includes a first cylindrical section and a second flared section, the heater is wound around the first section, and an extrusion outlet section is defined between the second section and the outer shell, specifically, the heater is configured to convert a cold airflow flowing through the heater into a hot airflow, the heater may be a heat conducting wire connected to a heat source, or may be a device capable of generating heat directly, in this embodiment, the preferred heater includes a heating wire 122 connected to a heat source, the heating wire 122 has good plasticity, that is, the heating wire 122 can be bent into any shape according to the requirements of a usage scenario, so that the heating wire 122 can be wound around the first section, which is beneficial to simplify the structure of the heater, and reduces the manufacturing difficulty and cost, and because the airflow flows along the first section and the second section in sequence, the cold air flow can be compressed and pressurized by the second section after being heated, so that the hot air flow blown out by the hair dryer has higher air pressure and air speed, and the hair drying efficiency is higher.

As shown in fig. 2, the inner wall 111 further includes an end wall 112 spanning the second section, and the end wall 112 is recessed toward the position of the fan unit 16, such that the end wall 112 shields the structural members in the cylindrical structure formed by the inner wall 111 from direct observation by the user and affecting the aesthetic appearance of the hair dryer.

The joint between the first section and the second section has poor stability due to the different diameters of the first section and the second section, and the joint between the first section and the second section is more firm and reliable due to the arrangement of the reinforcing ribs.

As shown in fig. 2, the fan unit 16 includes a fan and a motor 17 for driving the fan to rotate, the motor 17 extends into the inner wall 111, and the motor 17 abuts against the inner wall 111, specifically, the motor 17 is mounted on a motor bracket 18, the fan is also mounted in the motor bracket 18, and the motor 17 and the fan are respectively disposed at two sides of the motor bracket 18, and the other end of the motor 17 extends into the inner wall 111, so that the motor is convenient to mount, and does not occupy the space of the air passage, so that the air flow can pass through the air passage more smoothly, and by abutting against the motor 17 through the inner wall 111, the resonance generated by the vibration of the motor 17 can be reduced, the vibration felt by the user can be reduced, and the user experience is better.

As shown in fig. 2 and 7, a water ion passage separated from the air passage is further provided in the housing 1, a water ion generator 130 for generating water ions is provided in the water ion passage, a water ion outlet 131 is provided at a downstream end of the water ion passage, a cylindrical body 120 for separating the air passage and the water ion passage is provided in the housing 1, the cylindrical body 120 surrounds the heater, the water ion generator 130 is provided between the cylindrical body 120 and the housing 1, and the housing 1 has a cylindrical shape.

The water ion path is separated from the air path, so as to avoid that the water ions generated by the water ion generator 130 are lost by the hot air flow in the air path to influence the hair care effect of the hair dryer, in this example, the water ion path is arranged at the side part of the air path, so that the influence of the water ions in the water ion path on the air path is minimal, it can be understood that the air path can also be arranged around the water ion path, or the water ion path can also be arranged around the air path, and the position of the water ion outlet 131 is matched with that of the water ion path, that is, the water ion outlet 131 is arranged at the position opposite to the water ion generator 130 in the water ion path, so that the distance from the water ion generator 130 to the water ion outlet 131 is shortened as much as possible, and the water ions generated by the water ion generator 130 are prevented from being lost due to the overlong channel.

As shown in fig. 2 and 7, in which the cylinder 120 separates the water ion path from the air path, in this case, the water ion path is provided between the outer wall of the cylinder 120 and the inner wall of the housing 1, and the air path is provided inside the cylinder 120, so that the inside of the cylinder 120 is provided with a heater so that the cold air can be heated into hot air when flowing through the cylinder 120.

As shown in fig. 1, in which the casing 1 is cylindrical, so that the overall appearance of the hair dryer is simple and beautiful, the cylindrical shape in this embodiment can be reasonably interpreted as a three-dimensional structural member with a certain length, such as a cylinder, a square column, etc., and the preferred embodiment of this embodiment adopts a cylindrical structure, it can be understood that when the casing 1 adopts a cylindrical structure other than a cylinder, the arrangement of the internal structural members needs to be slightly adjusted, and the advantages of this embodiment can also be realized.

The cylinder 120 has a sinking platform sinking toward the axial direction of the heater, and the water ion generator 130 is disposed on the sinking platform, specifically, the sinking platform is used for mounting the water ion generator 130 in this example, but the shape of the sinking platform is not limited in this example, but the shape of the sinking platform at least should cover the water ion generator 130 so as not to affect the shape of the cylindrical housing 1, and the cylinder 120 in this example preferably has a cross-sectional shape of the sinking platform as "D", and the vertical side corresponds to the position of the sinking platform for mounting the water ion generator 130, and the sinking platform may be disposed in other shapes as long as the water ion generator 130 can be mounted.

As shown in fig. 2, the heater includes a bracket 121 and a heating wire 122 wound on the bracket 121, a section of the heating wire 122 corresponding to the sinking platform is linear, specifically, the bracket 121 is used to support the heating wire 122, so that the heating wire 122 is suspended on the bracket 121, and the heating wire 122 is prevented from directly contacting the inner wall 111, so that heat generated by the heating wire 122 is dispersed and transferred to the inner wall 111, and thus the air flow cannot be heated to a proper temperature, and meanwhile, the internal space of the inner wall 111 is prevented from being heated too high to damage structural members arranged inside the inner wall 111, the heating wire 122 presents a straight line at the sinking platform, and the straight line portion of the heating wire corresponds to the water ion generator 130, so that water ions generated by the water ion generator 130 are prevented from being evaporated by hot air of the blower, and further, the loss amount of the water ions is smaller.

As shown in fig. 5, the heating wire 122 is wound on the bracket 121 in a D shape, specifically, the water ion generator 130 is correspondingly installed on a linear section of the heating wire 122, so that the blower does not need to arrange the water ion generator 130 on a single convex part of one side of the blower, and the overall aesthetic measure of the blower is reduced.

As shown in fig. 3, the cross-sectional shape of the cylinder 120 is D-shaped, and specifically, the cylinder 120 is D-shaped, so that an installation space is formed between the horizontal section of the cylinder 120 and the inner wall of the curved housing 1, and the installation space is used for installing the water ion generator 130, and the cylinder 120 can separate the air passage from the water ion generator 130, so as to prevent hot air in the air passage from affecting the concentration of water ions generated by the water ion generator 130.

As shown in fig. 1 and 2, the end of the cylinder 120 is provided with a water ion outlet 131, and the ion emitting needle of the water ion assembly is disposed toward the water ion outlet 131, specifically, in this example, the end of the cylinder 120 is the end of the cylinder 120 facing the air outlet, so that the water ion outlet 131 is disposed toward the air outlet, that is, when the blower guides the air flow to dry hair through the air outlet 101, the water ions generated in the water ion outlet 131 can also act on the hair, so that the dry hair is more flexible.

Wherein, the ion emission needles have at least two, and the arrangement direction is perpendicular to the connecting line of one of the edges of the air outlet 101 and the center of the air outlet 101, specifically, because the water ion concentration is in positive correlation with the number of the ion emission needles, when the ion emission needles have at least two, the water ion concentration is higher, and then the hair is more flexible, but when the ion emission needles have more number, although the water ion concentration is higher, the volume of the water ion generator 130 is larger, and then the water ion generator occupies a larger installation space, so that the space of the air passage is compressed, the blowing amount of the hair drier is reduced, and the hair drying efficiency of the hair drier is affected, in this case, the preferable arrangement of two ion emission needles can improve the water ion generation concentration without causing the volume of the water ion generator 130 to be too large, the reduction of the blowing efficiency of the blower is avoided; the arrangement direction of the two ion emission needles is perpendicular to the connection line from one point of the center of the air outlet 101 to one point of the edge of the air outlet, so that the two ion emission needles are transversely arranged, the water ion generator 130 can generate larger water ion concentration while occupying smaller space, and the hair nursing effect of the hair drier is better.

It can be understood that if the inner wall 111 is made of a material with a better heat insulation performance, the heater can be directly disposed outside the inner wall 111, and the normal operation of the light assembly 19 inside the accommodating space is not affected by the heat generated by the heater.

Wherein, light subassembly 19 can play the indicative function to the state of blowing of hair-dryer on the one hand, makes the user can be more convenient see the operating condition of hair-dryer, and on the other hand light subassembly 19 plays the decoration effect, makes the whole more pleasing to the eye of hair-dryer.

As shown in fig. 2, wherein the projected area of the light assembly 19 at the air outlet 101 is at least greater than or equal to the cross-sectional area of the motor 17, specifically, since the motor 17 is a bulky structural component in the hair dryer, when the motor 17 is closer to the air outlet 101, the motor 17 is easily seen by the user through the air outlet 101 to affect the aesthetic property of the hair dryer, and when the projected area of the light assembly 19 at the air outlet 101 is greater than or equal to the cross-sectional area of the motor 17, the light assembly 19 shields the motor 17 at the air outlet 101 from being directly observed by the user, and at the same time, the light assembly 19 serves as an indication of the blowing state of the hair dryer, so that the user can visually feel the current blowing state, and the user experience is better.

As shown in fig. 2, the heater and the light assembly 19 are disposed in a staggered manner and the light assembly 19 is located at the end of the inner wall 111, specifically, in this example, the heater and the light assembly 19 are disposed at two sides of the inner wall 111 respectively and disposed on different straight lines, so that heat generated by the heater is radiated to the light assembly 19 as much as possible, and interference to normal operation of the light assembly 19 is avoided, and when the light assembly 19 is disposed at the end of the inner wall 111, the light assembly 19 is disposed at a position closer to the air outlet 101, and then a light propagation path generated by the light assembly 19 is shortest, so that a display effect of the light assembly 19 is better, and the assembly is more advantageous, because the light assembly 19 is closer to the air outlet 101, and the assembly operation is facilitated.

As shown in fig. 11 and 12, wherein the light assembly 19 includes a light emitting assembly 191 for generating light and a light guide 192 for guiding the light, the light guide member 192 is disposed across the inner wall 111, one side of the light guide member 192 covers the light emitting module 191, and the other side of the light guide member 192 is at least partially attached to the end wall 112, specifically, the light emitting module 191 is used for generating light, the light guide member 192 is used for guiding light, so that the light is emitted in a designated direction, and the light guide 192 spanning the interior wall 111 facilitates securing the light guide 192 in the interior wall 111, the term of crossing in this embodiment means that the periphery of the light guide 192 is closely attached to the inner wall of the inner wall 111, the light guide 192 covers the light emitting module 191 so that the light generated by the light emitting module 191 is transmitted to the outside through the light guide 192, the light guide member 192 is at least partially attached to the end wall 112, so that the attachment can save the installation space in consideration of installation; on the other hand, the medium which needs to pass through in the light transmission process is reduced, so that the light refraction is reduced, and the light effect presented on the end wall 112 is better.

Specifically, the light generated by the light emitting assembly 191 needs to pass through the light guide 192 and the end wall 112 in sequence, so that the transmittance of the light guide 192 needs to be greater than the transmittance of the end wall 112, so that the light needs to pass through the light guide 192 first and then pass through the end wall 112 to be observed by a user, if the transmittance of the light guide 192 is less than the transmittance of the end wall 112, when the light passes through the light guide 192, a part of the light cannot pass through the light guide 192, so that the brightness of the light exiting the light guide 192 is low, when the light passes through the end wall 112 again, the brightness of the light is further reduced, so that the light appearing on the end wall 112 is weak, and further, the lighting effect is poor, and the user experience is affected.

As shown in fig. 14, a side of the light guide 192 facing away from the end wall 112 includes a light-gathering portion 194, the light-emitting assembly 191 includes a light source (not shown), the light-gathering portion 194 substantially corresponds to the light source, and specifically, a side of the light guide 192 facing away from the end wall 112 includes a light-gathering portion 194, that is, a side of the light guide 192 facing toward the light-emitting assembly 191 is provided with a light-gathering portion 194, so that light enters the light guide 192 from the light-gathering portion 194 to form a relatively gathered light, the gathered light may be of a certain shape under the influence of the shape of the light-gathering portion 194, so that the light formed on the shape is brighter, when the light is transmitted to the end wall 112, so as to form a relatively strong light-dark contrast with the surroundings, and have a relatively large visual impact, so that the hair dryer is more beautiful, and when the light is used as an indicator, the indication effect is more obvious, and the light source substantially corresponds to the light-gathering portion 194, so that as much light generated by the light source is gathered by the light-gathering portion 194 and then appears on the end wall 112, so that the light effect is obtained by the light-gathering portion 194, so that the light effect is obtained by the light source is more as much as possible, and then appears on the end wall 112 More specifically, since the light irradiation has a divergence property and the luminance of the light gradually decreases from the center to the periphery, the light of the light source can be irradiated to the light condensing portion 194 even when the light condensing portion 194 is shifted from the center of the light source, and therefore, in this example, the light source can be substantially aligned with the light condensing portion 194, and the light source can be arranged with the center of the light source being shifted from the light condensing portion 194.

Wherein, the number of the light sources is at least 4, and the central angles between the adjacent light sources are substantially the same, specifically, the light generated by the light sources has divergence, so that the light at the center of the light sources is stronger, the light at the edges is weaker, when the number of the light sources is too small, light spots with different brightness are formed on the end wall 112, so that the indicating effect of the light component 19 is poorer, when the number of the light sources is more than or equal to 4, the distance between the adjacent light sources is smaller, the light at the edges of the adjacent light sources is overlapped, so that the light generated by the light emitting component 191 is substantially uniform, the light effect irradiated on the end wall 112 is better, and the central angles between the adjacent light sources are substantially the same, so that all the light sources are arranged in an annular array, and the light displayed on the end wall 112 is more uniform, the hair dryer is more beautiful, the meaning that the central angles are substantially the same in this example is that the light sources may have slight angle difference due to errors such as production and assembly, errors that do not affect the uniformity of the lighting effect presented on the end wall 112 are permissible, with the preferred number of light sources being 4 in this example and the central angle between adjacent light sources being 90 ° so that the light generated by the light sources is more uniform across the end wall 112 and the lighting effect is better.

As shown in fig. 15 and 16, the light-gathering part 194 is a saw-tooth structure, and particularly, the light-gathering part 194 is a preferred saw-tooth structure in this embodiment because the refraction angle γ is smaller than the incidence angle β when light enters the optically denser medium from the optically denser medium according to the law of refraction of light, the refraction angle γ is larger than the incidence angle β when light enters the optically denser medium from the optically denser medium, the light-gathering part 194 is a solid structure with a fixed shape belonging to the optically denser medium relative to air and belonging to the optically thinner medium relative to air, when the incident light 195 enters the light guide 192, it is refracted twice and then emitted from the light guide 192 toward one side of the end wall 112, since the light-gathering part 194 is saw-toothed, that is, the light-gathering part 194 is composed of several inclined planes that are not mirror images of each other, so that the incident plane 197 and the emitting plane 198 of light are arranged non-parallel, the direction of the emitted light 196 is different from the direction of the incident light 195, because the adjacent inclined planes are arranged in a mirror image mode, crossed emergent light 196 exists when light is emitted from the other surface of the light guide member 192, the light effect displayed on the end wall 112 can be stronger due to the crossed emergent light 196, and the indicating effect is more excellent.

It is understood that, in order to realize the light condensing effect of the specific shape on the end wall 112, the light condensing portion 194 of the sawtooth structure of the specific shape may be disposed on a side of the light guide 192 facing away from the end wall 112, and the specific shape is not limited to a circle, an ellipse, a square, a polygon, or an irregular shape.

As shown in fig. 15 and 16, the angle between adjacent saw teeth of the light-condensing portion 194 is α, wherein 0 ° < α < 180 °. When α is 180 ° or 0 ° according to the law of refraction of light, the light-gathering part 194 is a planar structure, that is, the incident surface 197 and the exit surface 198 of light are parallel planes, and when light penetrates through the light-gathering part 194 and enters the light guide 192, the light emitted from the other surface of the light guide 192 does not change direction, and is displayed on the end wall 112, which is a poor light effect; when the angle α is greater than 0 ° < α < 180 °, the light-condensing portion 194 is formed by connecting end to end a plurality of adjacent mirror-image inclined planes, when light is irradiated on the inclined planes, because the incident plane 197 and the emergent plane 198 of the light are arranged non-parallel, the direction of the light when the light is emitted out of the light guide 192 is different from the direction of the light incident, because the adjacent inclined planes are arranged in a mirror image manner, that is, the adjacent incident planes 197 are arranged non-parallel, there are intersecting light rays in the direction of the light emitted out of the light guide 192, and the intersecting light rays appear on the end wall 112 to generate a condensing effect, so that the light effect appearing on the end wall 112 is stronger, and the user experience is better, for example, when the angle α is 60 °, the angle α is 90 °, the angle α is 103 °, and the angle α is 150 °, experiments, and the preferable angle α in this example is 103 ° to 104 °.

As shown in fig. 12, a distance between the light emitting element 191 and the light guide 192 is H, wherein H is greater than or equal to 1mm and less than or equal to 10mm, specifically, when the light emitting element 191 is in operation, the light emitting element 191 generates heat, when the distance between the light emitting element 191 and the light guide 192 is too small, i.e., H is less than 1mm, the heat generated by the light emitting element 191 acts on the light guide 192, and when the light guide 192 is made of a material that is easily softened by heat, such as plastic, the structure of the light guide 192, even the light guide performance, is affected; when the distance between the light emitting assembly 191 and the light guide member 192 is too large, that is, H is greater than 10mm, on one hand, the distance between the light emitted by the light emitting assembly 191 and the light guide member 192 is relatively long, so that the light transmitted to the light guide member 192 is relatively weak, and further, the light effect presented on the end wall 112 is relatively weak, which results in poor use experience of the hair dryer, on the other hand, the size of the light assembly 19 is relatively large, and a larger space is required to install the light assembly 19, which results in an increase in the size of the hair dryer, which affects the aesthetic feeling of the hair dryer, and when H is greater than or equal to 1mm and less than or equal to 10mm, the light effect of the light assembly 19 can be optimal on the premise of ensuring that the hair dryer has a suitable installation space, for example, H is 3mm, H is 5mm, H is 8mm, and H is preferably 5 mm.

As shown in fig. 11 and 13, the hair dryer further includes a light shielding member 193, the light shielding member 193 is disposed between the light guiding member 192 and the end wall 112, specifically, the light shielding member 193 enables the light effect formed on the end wall 112 to have a certain shape, so that a specific display pattern can be formed on the end wall 112, meanwhile, the area of the end wall 112 corresponding to the light shielding member 193 is relatively dark, and the area corresponding to the light assembly 19 is relatively bright, such bright-dark contrast makes the relatively bright area more obvious, so that the light effect of the light assembly 19 on the end wall 112 will be better, in this embodiment, the light shielding member 193 is preferably circular, and further the relatively bright area of the end wall 112 is annular, so that the annular light effect is formed on the end wall 112, and the hair dryer is more beautiful.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, and improvements made within the technical scope of the present invention are included in the protection scope of the present invention.
