[0031] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0032] In the various specific technical features described in the specific embodiments, they can be combined in any suitable manner without conflict. For example, different embodiments and technical solutions can be formed by combining different specific technical features. To avoid unnecessary repetition, various possible combination methods of the specific technical features in the present invention will not be described separately.

[0033] In the following description, the terms "first / second / ..." involved are only used to distinguish different objects and do not indicate that there are the same or related relationships between the objects. It should be understood that the orientation descriptions "above", "below", "outside", and "inside" involved are all orientations in the normal use state, and the "left" and "right" directions represent the left and right directions shown in the specific corresponding schematic diagram, which can be the left and right directions in the normal use state or not.

[0034] It should be noted that the term "comprising", "including" or any other variant thereof is intended to cover a non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or further includes elements inherent to such process, method, article or device. Without further limitation, the element defined by the statement "including one..." does not exclude the existence of another identical element in the process, method, article or device including the element. "Plural" means greater than or equal to two.

[0035] Such as Figure 1As shown in the figure, a nourishing chamber 1 provided by an embodiment of the present invention is used to store hair care essential oil inside. The hair care essential oil acts on the hair and has the effects of protecting the hair from high-temperature damage and improving the softness of the hair. Specifically, the nourishing chamber 1 is usually connected to the air outlet end of the hair dryer, so that the hair care essential oil can volatilize following the airflow generated by the hair dryer, and the gas molecules formed by volatilization follow the airflow and blow towards the hair. Thus, it adheres to the hair to achieve the purpose of nourishing the hair.

[0036] The above-mentioned "nourishing" means that the hair care essential oil can have the effects of deep repair and nourishment on the hair. Acting the hair care essential oil on the hair can improve the problems of damage and frizzy hair that occur during the process of drying the hair at high temperature.

[0037] As Figures 1 to 3 As shown in the figure, the nourishing chamber 1 provided by an embodiment of the present invention includes a chamber body 11, a chamber cover 12 and a seal 13. An essential oil storage cavity 111 for accommodating the hair care essential oil is formed inside the chamber body 11, and an opening communicating with the essential oil storage cavity 111 is provided on the chamber body 11. Through this opening, the hair care essential oil can be loaded into the essential oil storage cavity 111. The chamber cover 12 is covered on one end of the chamber body 11 with the opening and is connected to the chamber body 11. At the same time, a circulation port 121 communicating with the essential oil storage cavity 111 is provided on the chamber cover 12. With such a setting, the chamber cover 12 and the chamber body 11 form an internal hollow structure. The hair care essential oil is loaded into the essential oil storage cavity 111, and the external flowing airflow will enter the essential oil storage cavity 111 from the circulation port 121. At the same time, the airflow carrying the volatilized essential oil molecules in the essential oil storage cavity 111 will also flow out through the circulation port 121, and then follow the airflow and blow towards the user's hair. After the volatilized essential oil molecules adhere to the hair, the nourishment of the hair is achieved.

[0038] As Figure 3 As shown in the figure, in an embodiment of the present invention, in order to avoid leakage of the hair care essential oil in the essential oil storage cavity 111, a leak-proof structure is provided on at least one of the chamber cover 12 and the chamber body 11. Specifically, when the leak-proof structure is provided on the chamber cover 12, it can increase the difficulty of leakage of the hair care essential oil through the circulation port 121, thereby playing a role in further preventing the hair care essential oil from leaking. And when the leak-proof structure is provided on the chamber body 11, it can collect the leaked hair care essential oil (such as leakage through the circulation port 121 or leakage from the gap between the chamber body 11 and the chamber cover 12), and can prevent the hair care essential oil from further leaking into the air duct, so as to better avoid the problem that the leaked hair care essential oil flows into the air duct and blows towards the hair in the form of larger liquid droplets, resulting in a poor hair care effect. And when leak-proof structures are provided on both the chamber cover 12 and the chamber body 11, it has a dual leak-proof function, providing double protection and further enhancing the reliability of avoiding leakage of the hair care essential oil and / or flowing into the air duct.

[0039] In an embodiment of the present invention, a nourishing bin 1 is provided, which includes a bin body 11 and a bin cover 12. An inner part of the bin body 11 forms a material protection cavity 111 for accommodating hair care essential oil and is provided with an opening communicating with the material protection cavity 111. The bin cover 12 is covered on one end of the bin body 11 having the opening and is connected to the bin body 11. By adopting a leak-proof structure provided on at least one of the bin cover 12 and the bin body 11. In this way, under the protection of the provided leak-proof structure, it is possible to prevent the hair care essential oil from leaking or to block and collect the leaked hair care essential oil, so as to avoid the leaked hair care essential oil from further flowing into the air duct and affecting the user experience. The nourishing bin 1 can reliably store the hair care essential oil, has a good leak-proof effect, will not have large particle hair care essential oil blown out to reduce the use experience, and has good use reliability.

[0040] As Figure 3 shown, in some embodiments, the leak-proof structure includes a leak-proof groove 141 provided on the bin body 11 and a liquid absorbing member 142 provided in the leak-proof groove 141. The leak-proof groove 141 is arranged around the contour shape of the bin cover 12. Specifically, the size of the contour edge of the bin body 11 is larger than the size of the contour edge of the bin cover 12, so that after the bin cover 12 is connected to the bin body 11, the positive projection of the contour edge of the bin cover 12 in the vertical direction is located within the area enclosed by the contour edge of the bin body 11. In this way, from the projection direction, the leak-proof groove 141 is located outside the contour edge of the bin cover 12. And since a sealing member 13 is provided at the connection between the bin body 11 and the bin cover 12, the hair care essential oil leaking from the material protection cavity 111 usually flows out through the circulation port 121. Therefore, by arranging the leak-proof groove 141 around the contour shape of the bin cover 12, no matter from which arbitrary edge of the circulation port 121 the hair care essential oil leaks, there will be a corresponding leak-proof groove 141 to block it, and the leaked hair care essential oil will flow into the leak-proof groove 141. Moreover, by providing the liquid absorbing member 142 in the leak-proof groove 141, it is possible to absorb the hair care essential oil flowing into the leak-proof groove 141, so that the leaked hair care essential oil can be collected on the liquid absorbing member 142, further improving the reliability of blocking the leaked hair care essential oil.

[0041] Specifically, in actual use, when the nourishing bin 1 is placed in a side-standing manner, it is easy for the hair care essential oil to flow out from the lowermost edge of the circulation port 121. Therefore, arranging the leak-proof groove 141 around the contour shape of the bin cover 12 can not only effectively collect the hair care essential oil flowing out through the circulation port 121. Moreover, since the leak-proof groove 141 is arranged around the bin cover 12, even if the hair care essential oil leaks from the gap between the bin body 11 and the bin cover 12, it can be collected through the leak-proof groove 141 and the liquid absorbing member 142, and the leak-proof effect is reliable.

[0042] The liquid absorbent member 142 can be made of a material that can absorb and store a certain amount of liquid, such as sponge, resin, activated carbon, etc. The liquid absorbent member 142 can be set according to the shape of the leak-proof groove 141, or can be set as a single independent entity, and then filled in the leak-proof groove 141 according to the usage needs, with good flexibility in setting and using.

[0043] As Figure 3 shown, in some embodiments, the leak-proof structure can also include a flange 143 provided on the cover 12 of the cartridge. The flange 143 is located at the edge of the cover 12 for forming the circulation port 121 and protrudes towards the inside of the material protection cavity 111. Specifically, the flange 143 is continuously arranged along the contour edge of the circulation port 121, and the free end protrudes towards the direction where the material protection cavity 111 is located. With this setting, in the side-standing use state, the flange 143 is equivalent to increasing the height of the edge of the circulation port 121, thereby increasing the difficulty of the hair care essential oil flowing out from the edge of the circulation port 121. Moreover, protruding towards the direction where the material protection cavity 111 is located will not reduce the area of the circulation port 121, thus not affecting the efficiency of air flow exchange in the material protection cavity 111, and further not affecting the volatilization effect of the hair care essential oil, and can effectively nourish the hair. The setting of this leak-proof structure can not only better prevent the hair care essential oil from leaking, but also ensure the hair care efficiency of the hair care essential oil, with good design ingenuity.

[0044] In some embodiments, the above corresponding leak-proof structures can be simultaneously provided on the cartridge body 11 and the cover 12 of the cartridge, so that the nourishing cartridge 1 has a double leak-proof performance, improving the reliability of preventing the hair care essential oil from leaking, and further improving the user experience.

[0045] In some embodiments, as Figure 3 shown, the top of the cover 12 is set to be inclined, and is inclined from the contour edge of the top of the cover 12 towards the edge of the circulation port 121. Specifically, taking Figure 3 the direction shown as a reference, the "top of the cover 12" refers to Figure 3 the uppermost part of the cover 12 shown in, which can also be called the top surface. Inclining the top of the cover 12 towards the edge of the circulation port 121 can at least guide the air flow into the material protection cavity 111 and increase the speed of the air flow entering, thereby improving the volatilization efficiency of the hair care essential oil and being beneficial to improving the effect of hair nourishment.

[0046] In some embodiments, as Figure 3As shown, a sealing groove 122 is formed on the side wall of the bin cover 12, and a plug connector 113 protrudes from the top of the bin body 11. The plug connector 113 is inserted into the sealing groove 122. Among them, a seal 13 is arranged in the sealing groove 122, and the seal 13 abuts between the bin cover 12 and the plug connector 113. In this way, through the cooperative design of the plug connector 113 and the sealing groove 122, the plug connector 113 is located in the sealing groove 122 and will not loosen randomly, making the connection between the bin body 11 and the bin cover 12 more reliable. And by installing the seal 13 in the sealing groove 122, the position of the seal 13 can also be limited by the sealing groove 122, and the sealing position of the seal 13 will not shift. Furthermore, under the abutment of the plug connector 113, the seal 13 undergoes elastic deformation, thereby achieving reliable sealing.

[0047] Specifically, the bin cover 12 can be connected to the bin body 11 by means of snap connection or threaded connection, etc. A seal 13 is arranged at the connection between the two to prevent the hair care essential oil from leaking through the gap between the two. The seal 13 can be made of elastic silicone or rubber material, so that when the bin cover 12 and the bin body 11 are connected, it can undergo elastic deformation to achieve reliable sealing. In some embodiments, as Figure 3 shown, a snap 123 is arranged on the bin cover 12, and a protrusion 114 is arranged on the inner wall of the bin body 11 for forming the material protection cavity 111. By snapping the snap 123 with the protrusion 114, the fixed connection between the bin cover 12 and the bin body 11 can be realized. At the same time, after snapping, a state of squeezing the seal 13 can be formed, thereby achieving the effect of sealing the gap between the bin cover 12 and the bin body 11.

[0048] Specifically, the snap 123 is formed by extending the bottom of the bin cover 12 towards the bottom of the material protection cavity 111. There are at least two snaps 123, and they are symmetrically distributed. The snap 123 has a certain elastic deformation performance, and there is a hole on the snap 123 for accommodating the protrusion 114. Thus, during the assembly connection, by inserting the protrusion 114 into the hole on the snap 123, the fixed connection between the bin cover 12 and the bin body 11 can be realized. The connection structure is simple and has good reliability. Moreover, both the snap 123 and the protrusion 114 are located in the material protection cavity 111. After the assembly of the bin cover 12 is completed, the snap 123 and the protrusion 114 can be covered, making the connection between the bin cover 12 and the bin body 11 a hidden connection, improving the overall aesthetics.

[0049] In some embodiments, an extension wall may also be provided at the bottom of the bin cover 12 and on one side close to the circulation port 121. Moreover, the extension wall extends towards the bottom of the material protection cavity 111 and laps with the inner wall of the bin body 11 for forming the material protection cavity 111. In this way, by lapping the extension wall with the inner wall of the bin body 11 for forming the material protection cavity 111, the path length of the hair care essential oil flowing towards the seal 13 is extended, thereby increasing the difficulty of leakage of the hair care essential oil and further improving the anti-leakage performance of the nourishing bin 1.

[0050] In some embodiments, as Figure 3 shown, the nourishing bin 1 further includes a material storage member 15 for storing hair care essential oil, and the material storage member 15 is arranged in the material protection cavity 111. Specifically, the material storage member 15 can be made of a material having the ability to absorb and store a certain amount of liquid, such as sponge, resin, activated carbon, etc. Moreover, in the direction perpendicular to the axis of the material storage member 15 and the material protection cavity 111, the cross-sectional shapes obtained by the material storage member 15 and the material protection cavity 111 are basically the same, so that the material storage member 15 can be installed in the care cavity. The outer wall of the material storage member 15 and the inside of the material protection cavity 111 can be kept in contact, or by reducing the size of the material storage member 15, an appropriate distance (such as 1 mm - 2 mm, etc.) can be provided between the two, so as to facilitate the contact between the air flow and the material storage member 15 and improve the efficiency of hair care by the hair care essential oil. Similarly, the bottom of the material storage member 15 and the bottom of the material protection cavity 111 can also be kept in contact, or by providing a support block at the bottom of the material protection cavity 111, a gap is formed between the bottom of the material storage member 15 and the bottom of the material protection cavity 111, which is convenient for the air flow to enter the bottom of the material storage member 15 and can also play a role in increasing the storage amount of the hair care essential oil.

[0051] The material storage member 15 is correspondingly made into a part with a certain thickness according to the shape of the material protection cavity 111, such as cylindrical. Moreover, in order to improve the efficiency of air flow exchange in the material protection cavity 111, as Figure 3 shown, the height of the material storage member 15 is also set such that after it is installed in the material protection cavity 111, the vertical distance L between the top surface of the material storage member 15 and the bottom edge of the circulation port 121 is between 1 - 3 mm. In this way, there is an interval of the above distance between the top surface of the material storage member 15 and the bottom surface of the bin cover 12, and the formed gap is convenient for air flow, so that the evaporation rate of the hair care essential oil is in a better state, thereby improving the utilization rate of the hair care essential oil.

[0052] Specifically, the vertical distance between the top surface of the material storage member 15 and the bottom edge of the circulation port 121 is between 1 mm - 3 mm. It can be 1 mm, 1.5 mm, 2 mm, 2.5 mm or 3 mm. It can also be any other value within the range of 1 mm - 3 mm. In the embodiments of the present invention, setting the distance between the two to be between 1.5 mm - 2.5 mm can make the utilization rate of the hair care essential oil reach a better state.

[0053] In some embodiments, since the material storage member 15 is detachably mounted in the bin body 11, different types of hair care essential oils can be stored by replacing the material storage member 15, thereby meeting the usage requirements for different types of hair care essential oils. The usage method is flexible and can meet different usage requirements.

[0054] As Figure 4 and Figure 5 shown, in an embodiment of the present invention, a nozzle assembly 2 is further provided, which is connected to the housing of the hair dryer. The nozzle assembly 2 includes a nozzle 21 and the nourishing bin 1 described in any of the above embodiments. The nozzle 21 is connected to the housing through a fixing member 213. An accommodation cavity 210 is formed inside the nozzle 21, and at least a part of the nourishing bin 1 is installed in the accommodation cavity 210. Moreover, an air duct 211 communicating with the air outlet of the hair dryer is formed on the nozzle 21. Part of the air flow passing through the air duct 211 is mixed with the air flow above the material protection cavity 111 (refer to Figure 3 ) to drive the volatilization of the hair care essential oil. With such a setting, through the connection function of the fixing member 213, the nozzle assembly 2 can be detachably connected to the housing of the hair dryer. After the nozzle assembly 2 is connected to the housing, the air duct 211 on the nozzle 21 is communicated with the air outlet of the hair dryer. Thus, the wind generated by the hair dryer will flow into the air duct 211, and at least part of the air in the air duct 211 will enter above the material protection cavity 111 and be mixed with the air flow above the material protection cavity 111 to drive the air flow in the material protection cavity 111, so that the hair care essential oil volatilizes. The volatilized essential oil molecules will gather again on the blowing path of the air duct 211 and finally blow onto the user's hair and adhere to it, achieving the effect of nourishing the hair.

[0055] Specifically, the fixing member 213 can be a snap member or a magnetically attractable part. The nozzle assembly 2 is detachably connected to the housing of the hair dryer, thereby improving the flexibility of use. The user can choose whether to use the nozzle assembly 2 to nourish the hair according to actual usage needs, or choose to connect a nozzle assembly 2 with different types of hair care essential oils. The nozzle assembly 2 can relatively reliably achieve the nourishment of the hair, has good practicability, and is convenient to use.

[0056] In some embodiments, such as Figure 4 and Figure 6As shown, the air nozzle assembly 2 further includes an air guiding member 22. The air guiding member 22 is located in the accommodation cavity 210 and is connected to the air nozzle 21 and / or the nourishing chamber 1. An air inlet 221 and an air outlet 222 are respectively provided on the air guiding member 22. In this way, at least part of the air flowing out of the air duct 211 sequentially enters the material protection cavity 111 via the air inlet 221 and the circulation port 121, and the air in the material protection cavity 111 sequentially flows out via the circulation port 121 and the air outlet 222. Moreover, the air flowing out of the material protection cavity 111 is gathered again on the air outlet path of the air duct 211, and then blows towards the user's hair together with the other air in the air duct 211 that does not enter the material protection cavity 111. In the embodiment of the present invention, the air blowing port is arranged adjacent to the air duct 211, and the air outlet 222 faces the air outlet path of the air duct 211. In this way, by arranging the air guiding member 22, the air flowing out of the air duct 211 can be guided into the material protection cavity 111, improving the volatilization efficiency of the hair care essential oil. At the same time, the air guiding member 22 can also guide the air flowing out of the material protection cavity 111 to gather on the air blowing path of the air duct 211, so that the air carrying the hair care essential oil molecules can blow towards the user's hair, thereby improving the utilization rate of the hair care essential oil.

[0057] Specifically, the connection between the air guiding member 22 and the air nozzle 21 and / or the nourishing chamber 1 can be achieved by snap connection or bonding. For example, a detachable connection can be achieved by magnetic attraction among the three. The specific implementation method can be that magnetic members capable of attracting each other are respectively provided on the air guiding member 22, the air nozzle 21, and the nourishing chamber 1, so as to be attracted to each other to achieve connection; or a magnetic member can be provided on the air nozzle 21, and two of the air guiding member 22 and the nourishing chamber 1 are made of ferromagnetic metal, or one of them is made of ferromagnetic metal and the other is made of a magnetic member. In this way, a detachable connection among the air guiding member 22, the air nozzle 21, and the nourishing chamber 1 can be achieved. In the embodiment of the present invention, as Figure 6 shown, a third connecting member 227 is provided on the air guiding member 22, and the third connecting member 227 is made of ferromagnetic metal, and the second connecting member 214 provided on the air nozzle 22 is a magnetic member, so that the two can be attracted and connected.

[0058] In some embodiments, such as Figure 4 and Figure 7As shown, the air guiding member 22 includes a main body 223 and a top cover 224. The main body 223 is arranged in a ring shape, and an air inlet 221 is formed on the main body 223. The main body 223 is connected to the air nozzle 21 and / or the moisturizing chamber 1. The support rod 226 of the top cover 224 is connected to the main body 223, and there is a gap forming an air outlet 222 between the main body 223 and the top cover 224. Specifically, the main body 223 is arranged to match the contour shape of the bin body 11 so as to be able to be installed and connected to the moisturizing chamber 1. The main body 223 and the top cover 224 are not completely fitted, but there is a gap forming the air outlet 222. In this way, the essential oil molecules volatilized in the material protection cavity 111 can directly flow out from the air outlet 222. The connection between the main body 223 and the top cover 224 can be to form an annular support structure on the main body 223 for the clamping installation or gluing of the top cover 224, etc., or can be connected and fixed by arranging support rods. Of course, the main body 223 and the top cover 224 can also be formed by an integral molding method, and the setting methods are diverse and the flexibility is good.

[0059] In some embodiments, as Figure 4 and Figure 7 shown, a plurality of air inlets 221 are arranged at intervals, and moreover, the air inlets 221 are distributed at intervals along the contour shape of the main body 223. In this way, the arrangement of the air inlets 221 makes the main body 223 in a grid shape. By adopting the grid air inlet method, the generation of inlet air noise can be effectively reduced, and the comfort of use can be improved. Moreover, the surrounding air inlets 221 can realize air inlet at all circumferential positions, which improves the air volume of air inlet into the material protection cavity 111, and further improves the volatilization efficiency of the hair care essential oil.

[0060] Specifically, the top cover 224 is arranged at intervals with the main body 223, so that the support rod 226 can form a gap with the main body 223. This gap is located above the air inlets 221 and becomes the air outlet 222 for the air flow flowing out from the material protection cavity 111. In this setting method, the formed air outlet 222 is also continuously distributed along the contour shape of the main body 223. That is, the air outlet 222 is arranged circumferentially around the main body 223 and matches the contour shape of the air duct 211. Thus, the air guiding member 22 realizes circumferential air outlet along the contour shape, and the air outlet uniformity is good. And, the contour edge of the top cover 224 can also be set as a flanging, and the flanging is tilted away from the main body 223, so as to be able to increase the area of the air outlet 222. In this way, not only the air volume can be increased, but also when disassembling and assembling the air guiding member 22, by holding the flanging part, the convenience of taking and placing is improved.

[0061] In the embodiment of the present invention, the nozzle assembly 2 provided has a dual air outlet structure of discharging air through the air duct 211 and through the air outlet 222, and makes the air flowing out of the air outlet 222 directly converge onto the air outlet path of the air duct 211. The air flowing out from two different positions converges and blows onto the hair together, thereby being able to improve the utilization rate of the volatilized hair care essential oil.

[0062] In some embodiments, as Figure 4 and Figure 7 shown, the air guiding member 22 further includes a support ring 225 protruding in a direction away from the nourishing chamber 1. The support ring 225 is connected to the main body 223 through a support rod 226, and the top cover 224 and the support ring 226 are connected through a snap structure. Specifically, the main body 223, the support ring 225, and the support rod 226 can be integrally formed, thereby improving the convenience of production and manufacturing. As an implementation scheme, a snap hole can be provided on the support ring 225, and a snap hook can be provided on the top cover 224. The combination of the snap hole and the snap hook forms a snap structure. In this way, the snap hook and the snap buckle cooperate with each other to connect, and the top cover 224 can be fixedly installed on the support ring 225, and the assembly convenience is good. Of course, the installation and fixation between the top cover 224 and the support ring 225 can also be realized by means of screw-like fasteners or adhesives, etc., and the connection methods are diverse. As Figure 7 shown, the support rod 226 is arranged between the support ring 225 and the main body 223, and at least two are evenly arranged, so as to stably support the support ring 225, and the overall structure of the air guiding member 22 formed has good stability and has sufficient structural strength to ensure the reliability and service life of use.

[0063] In some embodiments, as Figure 6 shown, the inner wall of the nozzle 21 for forming the air duct 211 has a wind guiding inclined surface 23, and the wind guiding inclined surface 23 is inclined towards the air guiding member 22 to guide the air flowing out of the air duct 211 to flow into the material protection cavity 111. In this way, the provided wind guiding inclined surface 23 can play a role in converging the air duct 211. Through the guidance of the wind guiding inclined surface 23, the air volume of the air flowing out of the air duct 211 blowing into the material protection cavity 111 can be increased, and at the same time, the temperature around the nourishing chamber 1 can also be increased, thereby increasing the volatilization efficiency of the hair care essential oil, and better improving the amount of the volatilized hair care essential oil molecules blowing onto the hair, realizing a better nourishing effect on the hair.

[0064] In some embodiments, as Figure 6As shown, the air guiding inclined surface 23 is arranged near the air outlet end of the air duct 211, and the inclination angle α of the air guiding inclined surface 23 relative to the central axis of the accommodating cavity 210 is set to 3° to 15°. In this way, by arranging it near the air outlet end, the air in the air duct 211 can be properly distributed, so that a part of the air in the air duct 211 can enter the material protection cavity 111 under the guidance of the air guiding inclined surface 23, ensuring the air inflow volume in the material protection cavity 111 (refer to Figure 3 ) and also improving the hair care efficiency of the hair care essential oil. At the same time, it also ensures that another part of the air in the air duct 211 can be directly blown out from the air outlet end. Moreover, the directly blown air forms a negative pressure environment at the air outlet 222, which attracts the air in the material protection cavity 111 to flow out and finally converges to be blown onto the hair in use, ensuring the drying and moisturizing hair care of the hair. Specifically, the inclination angle α of the air guiding inclined surface 23 can be any value within the range of 3° to 15°, such as 3°, 7°, 10° or 13°, etc. Any angle within this range can better realize the distribution of the air in the air duct 211. In the embodiment of the present invention, the inclination angle α of the air guiding inclined surface 23 can be set to 8°, so as to not only effectively distribute and guide the air in the air duct 211, but also have a noise reduction effect, making the noise generated when the air flows through the air duct 211 lower and improving the comfort of use.

[0065] In some embodiments, such as Figure 4 and Figure 6As shown, one end of the air nozzle 21 facing the housing is provided with a through hole 212 communicating with the accommodation cavity 210, so as to be able to push the nourishing bin 1 away from the air nozzle 21. Moreover, a first connecting member 16 is provided on the nourishing bin 1, and a second connecting member 214 is provided on the air nozzle 21. The first connecting member 16 and the second connecting member 214 are detachably connected. With such a setting, after the nourishing bin 1 is installed in the accommodation cavity 210, through the interaction between the first connecting member 16 and the second connecting member 214, the fixing of the connection position between the nourishing bin 1 and the air nozzle 21 is realized. Moreover, the first connecting member 16 and the second connecting member 214 are detachably connected, which can not only stably connect the nourishing bin 1 and the air nozzle 21, but also realize the quick disassembly between the two, so as to meet the use requirements of related operations such as disassembling, replacing or maintaining the nourishing bin 1 (such as adding hair care essential oil). By providing a through hole 212 on the air nozzle 21, after the nourishing bin 1 is installed in the accommodation cavity 210, a part of the structure of the nourishing bin 1 is located in the through hole 212. Thus, when it is necessary to disassemble the nourishing bin 1, by pressing the part of the nourishing bin 1 corresponding to the through hole 212, the nourishing bin 1 can be pushed, and then the nourishing bin 1 can be pushed out from the open end of the air nozzle 21 and disassembled. That is, in the embodiment of the present invention, only by pressing the nourishing bin 1, the disassembly of the nourishing bin 1 can be realized. Compared with the ways such as screw connection or adhesive fixation, this detachable connection structure through the cooperation of the first connecting member 16 and the second connecting member 214, combined with the structure design of pressing and disassembling by providing the through hole 212, has a simple overall structure and good ingenuity, enables the air nozzle 21 assembly to have the performance of convenient disassembly, and improves the actual use experience.

[0066] In some embodiments, both the first connecting member 16 and the second connecting member 214 are magnetic members that can attract each other. By setting it as a magnetic connection, the connection is convenient, the reliability is good, and it is also convenient to disassemble. It can also be that one of the first connecting member 16 and the second connecting member 214 is set as a magnetic member, and the other of the first connecting member 16 and the second connecting member 214 is set as a ferromagnetic metal member. Through the attraction generated by the magnetic member on the ferromagnetic metal member, the reliable connection between the two can also be realized, and the disassembly is convenient.

[0067] In another embodiment, the first connecting member 16 and the second connecting member 214 can be set into a snap 123 structure that can be cooperatively connected. For example, one of the first connecting member 16 and the second connecting member 214 is set as an elastic hook, and the other of the first connecting member 16 and the second connecting member 214 is correspondingly set as a buckle position (such as a concave pit behind the protrusion 114). In this way, the cooperative connection between the elastic hook and the buckle position can also realize the detachable connection between the nourishing bin 1 and the air nozzle 21, and it is also convenient to disassemble.

[0068] In some embodiments, such as Figure 6As shown in the figure, a convex edge 115 is formed on the outer wall surface of the moisturizing chamber 1, and a bearing platform 215 is formed on the inner wall surface of the air nozzle 21. The convex edge 115 is lapped on the bearing platform 215, the first connecting piece 16 is fixed on the convex edge 115, and the second connecting piece 214 is fixed on the bearing platform 215. Specifically, the first connecting piece 16 is fixed on the surface where the convex edge 115 and the bearing platform 215 are lapped or arranged inside the convex edge 115. A groove is provided on the bearing platform 215, and the second connecting piece 214 is fixedly installed in the groove. In this way, after the moisturizing chamber 1 is installed in the accommodating cavity 210, the convex edge 115 is lapped on the bearing platform 215 to provide support for the installation position of the moisturizing chamber 1. The first connecting piece 16 and the second connecting piece 214 attract each other when they are close to each other, so as to fix their installation positions.

[0069] In some embodiments, at least one of the convex edge 115 and the bearing platform 215 is set to be annular. In this way, a continuous connection structure surrounding the accommodating cavity 210 is formed, and the connecting pieces correspondingly arranged inside it are also continuously surrounded. In this way, no matter how the moisturizing chamber 1 and the air nozzle 21 are assembled in terms of position, the corresponding first connecting piece 16 and second connecting piece 214 attract each other to fix the installation position, reducing the difficulty of the installation position requirements during installation and improving the convenience of installing the moisturizing chamber 1.

[0070] In the embodiment of the present invention, a hair dryer is also provided, which includes a housing and the air nozzle assembly 2 provided in any of the above embodiments. The air nozzle 21 is connected to the air outlet end of the housing through a fixing member 213. Specifically, the air nozzle 21 and the housing are usually set to be detachably connected. Therefore, the fixing member 213 can be a thread, a magnetic member, or a snap 123 that can achieve detachable connection, etc. Since the air nozzle assembly 2 can make the hair care essential oil inside volatilize by means of the wind generated by the hair dryer, and can blow the volatilized essential oil molecules onto the user's hair to achieve moisturizing of the hair. Therefore, by providing the above air nozzle 21 assembly, the hair dryer can not only dry the hair, but also moisturize and protect the hair, enriching the use functions of the hair dryer. The air nozzle assembly 2 can also conveniently disassemble the moisturizing chamber 1, facilitating the replacement or supplement of the hair care essential oil, thereby improving the convenience and use experience of using the hair dryer.

[0071] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
