Description

Technical Field

[0001] This utility model relates to the field of hair dryer technology, and in particular to a diffuser nozzle structure and a hair dryer. Background Technology

[0002] Most hair dryers on the market today use high-speed motors to drive fans and generate strong airflow to quickly dry hair. However, this strong airflow also has some drawbacks. For example, for people with fragile or sensitive hair, strong airflow may cause scalp discomfort or even damage; in addition, concentrated and strong airflow can easily lead to localized overheating, damaging the hair cuticle. Utility Model Content

[0003] Based on this, this application provides a diffuser nozzle structure and a hair dryer, which can effectively reduce the air velocity at the hair dryer outlet and make the airflow gentler.

[0004] A diffuser nozzle structure includes: an outer shell having an air inlet and a mounting groove, the air inlet communicating with the mounting groove; an air outlet shell disposed on the outer shell and located at the opening of the mounting groove, the air outlet shell having a plurality of air outlets; and a heat insulation interlayer sandwiched between the outer shell and the air outlet shell, the heat insulation interlayer having a receiving cavity and a flow guide portion, the flow guide portion cooperating with a groove on one side of the receiving cavity to form a first air passage, the air inlet, the first air passage and the plurality of air outlets being sequentially connected, the air inlet direction intersecting the air passage direction of the first air passage.

[0005] The first aspect of this application discloses a diffuser nozzle structure. A first air passage with a guiding function is formed by the cooperation of the guide portion of the heat-insulating interlayer and a slot on one side of the receiving cavity. This causes the air inlet's airflow direction to intersect with the airflow direction of the first air passage. After the airflow enters through the air inlet, the guiding effect of the first air passage effectively reduces the wind speed, making the blown air more gentle and meeting the user's need for gentle blowing. The air outlet housing has several air outlets. After passing through the first air passage, the airflow is evenly distributed to each air outlet, ensuring uniform airflow distribution and avoiding excessively high or low wind speeds in some areas, thus improving the blowing effect and user experience. Furthermore, the heat-insulating interlayer not only guides the airflow but also effectively isolates heat transfer between the outer shell and the air outlet housing, preventing the outer shell from becoming too hot to handle and improving safety. The combined structure of the outer shell, air outlet housing, and heat-insulating interlayer achieves a gentler airflow from the diffuser nozzle structure. At the same time, it makes the overall structure of the diffuser nozzle more compact, ensuring high airflow efficiency while maintaining a gentler airflow.

[0006] In one embodiment, the flow guide section is provided with a flow guide slope, which cooperates with a slot on one side of the receiving cavity to form the first air passage. The air inlet's air intake direction intersects with the horizontal plane where the flow guide slope is located. By providing a flow guide slope in the flow guide section, and the flow guide slope cooperating with a slot on one side of the receiving cavity to form the first air passage, the airflow direction is effectively guided, allowing the airflow to be fully diffused and slowed down before entering the air outlet housing, further improving the softening effect of the airflow. Making the air intake direction of the air inlet intersect with the horizontal plane where the flow guide slope is located reduces the resistance of the airflow when passing through the first air passage, making the output airflow smoother.

[0007] In one embodiment, the airflow guide is provided with a second air passage, and the air inlet, the second air passage, and a plurality of air outlets are sequentially connected. By providing a second air passage in the airflow guide and sequentially connecting the air inlet, the second air passage, and the air outlets, the airflow path is increased. This design can further disperse the airflow, ensuring that the airflow is evenly distributed to each air outlet, avoiding excessively high or low local wind speeds, and improving the stability and consistency of the blowing effect.

[0008] In one embodiment, a protruding post is provided on the side of the air outlet housing away from the heat insulation layer. The protruding post is located at at least one air outlet, and the protruding post has at least three air outlet holes. The at least three air outlet holes are arranged at intervals around the protruding post, and each of the at least three air outlet holes communicates with at least one air outlet. By providing a protruding post with at least three air outlet holes, the diffuser nozzle structure can be used as a hair comb inserted into the hair to improve the efficiency of drying the hair. The at least three air outlet holes arranged at intervals around the protruding post allow the airflow to flow evenly from multiple directions, ensuring the stability and consistency of the drying effect. In addition, the structural design of multiple air outlet holes further makes the output airflow softer and more evenly distributed, avoiding strong winds hitting the scalp or causing frizzy hair, providing users with a more comfortable drying experience.

[0009] In one embodiment, the air outlet direction intersects with the air vent direction. This intersection of the air outlet and vent directions creates a multi-directional airflow, increasing airflow coverage and improving airflow efficiency, ensuring hair is dried or styled evenly. The multi-directional airflow design reduces concentrated hot air impact on the hair, preventing localized overheating or damage, while ensuring more even heating, thus enhancing user comfort and safety.

[0010] In one embodiment, the number of raised pillars is multiple, and the multiple raised pillars are evenly spaced. By evenly spaced multiple raised pillars, a larger area of ​​hair can be processed simultaneously, improving the overall efficiency of the device and shortening the time required to dry hair.

[0011] In one embodiment, the heat insulation interlayer includes a heat insulation interlayer body and a flow guide. The heat insulation interlayer body is sandwiched between the outer shell and the air outlet shell. The heat insulation interlayer body has the receiving cavity. The flow guide is disposed on the heat insulation interlayer body and located within the receiving cavity. The flow guide cooperates with a slot on one side of the receiving cavity to form the first air outlet. By sandwiching the heat insulation interlayer body between the outer shell and the air outlet shell, heat transfer can be effectively blocked, reducing the surface temperature of the outer shell and preventing burns to the user, while also improving the safety of the device. The flow guide cooperating with a slot on one side of the receiving cavity to form the first air outlet can prevent direct airflow from creating a strong impact that could damage the scalp or cause frizzy hair. Placing the flow guide within the receiving cavity allows for efficient use of internal space, making the device structure more compact, while ensuring unobstructed airflow.

[0012] In one embodiment, the outer casing has a plurality of abutment protrusions, which are spaced apart around the inner wall of the mounting groove. The end of the heat-insulating interlayer body away from the air outlet casing abuts against the plurality of abutment protrusions. By abutting against the heat-insulating interlayer body, the installation position of the heat-insulating interlayer body can be accurately positioned, ensuring a tighter fit between it and the outer casing and the air outlet casing, improving assembly accuracy and efficiency. The spaced arrangement of the plurality of abutment protrusions around the inner wall of the mounting groove provides uniform support for the heat-insulating interlayer body, preventing it from shifting or deforming due to uneven force, thereby enhancing the stability of the overall structure. Simultaneously, the arrangement of the plurality of abutment protrusions provides multi-point support for the heat-insulating interlayer body, reducing vibration during equipment operation.

[0013] In one embodiment, the heat-insulating interlayer body is provided with a plurality of protruding ribs, which are spaced apart on the outer wall of the receiving cavity and abut against the inner wall of the mounting groove. A first heat-insulating cavity is formed between the outer wall of the receiving cavity and the inner wall of the mounting groove. By having the plurality of protruding ribs on the outer wall of the receiving cavity abut against the inner wall of the mounting groove, a first heat-insulating cavity is formed between the heat-insulating interlayer and the outer shell, which can effectively block heat transfer, reduce the surface temperature of the outer shell, prevent users from being burned, and improve the safety of the equipment.

[0014] In one embodiment, at least a portion of the thermal insulation interlayer mates with the inner wall of the mounting groove to form an abutment groove. The air outlet housing has an abutment portion on its side facing the thermal insulation interlayer, extending into the abutment groove and abutting against the thermal insulation interlayer. By having at least a portion of the thermal insulation interlayer mate with the inner wall of the mounting groove to form an abutment groove, and the abutment portion on the air outlet housing extending into the abutment groove to abut against the thermal insulation interlayer, this design makes the connection between the outer shell, the thermal insulation interlayer, and the air outlet housing tighter, effectively enhancing the stability of the overall structure and preventing loosening or displacement of the overall structure due to vibration or external forces.

[0015] In one embodiment, the abutment portion, at least a portion of the air outlet housing, and the inner wall of the mounting groove cooperate to form a second heat insulation cavity. By forming this second heat insulation cavity through the cooperation of the abutment portion, at least a portion of the air outlet housing, and the inner wall of the mounting groove, heat transfer from hot air to the outer casing is blocked, preventing users from being burned during use and further improving the safety of the diffuser nozzle structure.

[0016] In one embodiment, the edge of the mounting groove forms a matching rib, and the air outlet housing is provided with a matching groove, with the matching rib fitting into the matching groove. The matching rib formed at the edge of the mounting groove, and its fitting with the matching groove of the air outlet housing, ensures accurate alignment between the air outlet housing and the outer housing, improving installation precision and enhancing connection stability. The cooperative design of the matching rib and the matching groove makes installation and disassembly between the air outlet housing and the outer housing more convenient, improving installation efficiency and reducing maintenance costs.

[0017] In one embodiment, the inner wall of the mounting groove is provided with a limiting groove, and the air outlet housing is provided with a limiting protrusion, which is adapted to the limiting groove. Through the precise cooperation between the limiting protrusion and the limiting groove, accurate positioning between the air outlet housing and the outer housing is achieved, preventing offset or misalignment during installation, while also enhancing the stability of the overall structure and preventing loosening due to vibration or external forces. Furthermore, the cooperative design of the limiting protrusion and the limiting groove enables rapid assembly between the air outlet housing and the outer housing, improving installation efficiency and reducing maintenance costs.

[0018] In one embodiment, the outer casing is provided with a first fastening part located on the inner sidewall of the mounting groove, and the air outlet housing is provided with a second fastening part on the side facing the outer casing. The first fastening part and the second fastening part are fastened together. This interlocking structure design makes the connection between the air outlet housing and the outer casing more stable, effectively preventing loosening or detachment due to vibration or external force, and improving the overall structural stability. Simultaneously, it makes the installation and disassembly of the air outlet housing and the outer casing more convenient, allowing for rapid assembly without complex tools or operations, improving installation efficiency and reducing maintenance costs.

[0019] A hair dryer includes: a handle assembly; a hair dryer assembly disposed on the hair dryer assembly; and a diffuser nozzle structure as described above, wherein the diffuser nozzle structure is detachably disposed on the hair dryer assembly.

[0020] The second aspect of this application discloses a hair dryer that, by incorporating a diffuser nozzle structure, effectively optimizes airflow diffusion, resulting in a more uniform and gentle airflow. The detachable design of the diffuser nozzle structure and the hair dryer assembly allows the user to install the diffuser nozzle structure to produce a gentler, more dispersed airflow, reducing damage to the hair and scalp; detaching the diffuser nozzle structure allows for a more concentrated airflow, suitable for quickly drying hair.

[0034] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0035] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0036] The diffuser nozzle structure and hair dryer of some embodiments of the present invention are described below with reference to the accompanying drawings.

[0037] Example 1

[0038] like Figures 1 to 8 As shown, this embodiment discloses a diffuser nozzle structure, including: an outer shell 1, the outer shell 1 having an air inlet 101 and a mounting groove 102, the air inlet 101 communicating with the mounting groove 102; an air outlet shell 2, the air outlet shell 2 being disposed on the outer shell 1 and located at the opening of the mounting groove 102, the air outlet shell 2 having a plurality of air outlets 201; a heat insulation interlayer 3, the heat insulation interlayer 3 being sandwiched between the outer shell 1 and the air outlet shell 2, the heat insulation interlayer 3 having a receiving cavity 301, the heat insulation interlayer 3 having a guide portion 32, the guide portion 32 cooperating with a groove on one side of the receiving cavity 301 to form a first air passage 302, the air inlet 101, the first air passage 302 being sequentially connected with the plurality of air outlets 201, the air inlet direction of the air inlet 101 intersecting with the air passage direction of the first air passage 302.

[0039] The first aspect of this application discloses a diffuser nozzle structure. A first air passage 302 with a guiding function is formed by the cooperation of the guide portion 32 of the heat insulation layer 3 and a slot on one side of the receiving cavity 301. This ensures that the air inlet direction of the air inlet 101 intersects with the air passage direction of the first air passage 302. After the airflow enters from the air inlet 101, it is guided by the first air passage 302, effectively reducing the wind speed and making the blown air more gentle, meeting the user's need for gentle blowing. The air outlet housing 2 is provided with several air outlets 201. After passing through the first air passage 302, the airflow is evenly dispersed to each air outlet 201, ensuring uniform airflow distribution and avoiding excessively high or low local wind speeds, thus improving the blowing effect and user experience. Furthermore, the heat insulation layer 3 not only serves as a guide but also effectively isolates heat transfer between the outer shell 1 and the air outlet housing 2, preventing the outer shell 1 from becoming too hot to handle and improving safety. The combined structure of the outer shell 1, the air outlet shell 2, and the heat insulation layer 3 makes the airflow from the diffuser structure gentler, while also making the overall structure of the diffuser structure more compact, ensuring high airflow efficiency while making the airflow gentler.

[0040] like Figure 2 and Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the guide section 32 is provided with a guide slope 321, and the guide slope 321 cooperates with a slot on one side of the receiving cavity 301 to form a first air passage 302, and the air inlet direction of the air inlet 101 intersects with the horizontal plane where the guide slope 321 is located. By providing a guide slope 321 in the guide section 32, and the guide slope 321 cooperating with a slot on one side of the receiving cavity 301 to form a first air passage 302, the airflow direction is effectively guided, so that the airflow is fully diffused and decelerated before entering the air outlet housing 2, further improving the softening effect of the wind speed. Making the air inlet direction of the air inlet 101 intersect with the horizontal plane where the guide slope 321 is located can reduce the resistance of the airflow when passing through the first air passage 302, making the output airflow softer.

[0041] like Figure 2 and Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the air guide 32 is provided with a second air passage 303, and the air inlet 101, the second air passage 303, and a plurality of air outlets 201 are sequentially connected. By providing the second air passage 303 in the air guide 32, and by sequentially connecting the air inlet 101, the second air passage 303, and the air outlets 201, the airflow path is increased. This design can further disperse the airflow, ensuring that the airflow is evenly distributed to each air outlet 201, avoiding excessively high or low local wind speeds, and improving the stability and consistency of the blowing effect.

[0042] like Figure 3 and Figure 8As shown, in addition to the features of the above embodiments, this embodiment further specifies that: a protruding column 211 is provided on the side of the air outlet housing 2 away from the heat insulation layer 3. The protruding column 211 is located at at least one air outlet 201. The protruding column 211 has at least three air outlet holes 202, which are spaced apart around the protruding column 211 and are all connected to at least one air outlet 201. By providing the protruding column 211 and having at least three air outlet holes 202 on it, the diffuser nozzle structure can be used as a hair comb inserted into the hair to improve the efficiency of drying hair. The spaced arrangement of at least three air outlet holes 202 around the protruding column 211 allows the airflow to flow out evenly from multiple directions, ensuring the stability and consistency of the drying effect. In addition, the structural design of multiple air outlet holes 202 further makes the output airflow gentler and more evenly distributed, avoiding strong winds hitting the scalp or making the hair frizzy, providing users with a more comfortable drying experience.

[0043] like Figure 6 and Figure 8 As shown, in addition to the features of the above embodiments, this embodiment further defines that the air outlet direction of the air outlet 202 intersects with the air outlet direction of the air vent 201. By intersecting the air outlet direction of the air outlet 202 with the air vent direction of the air vent 201, a multi-directional airflow can be formed, increasing the airflow coverage area and thus improving airflow efficiency, ensuring that the hair can be dried or styled evenly. The multi-directional airflow design reduces concentrated hot air impact on the hair, avoiding localized overheating or damage, while allowing the hair to be heated more evenly, improving user comfort and safety.

[0044] like Figure 6 and Figure 8 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the number of protruding pillars 211 is multiple, and the multiple protruding pillars 211 are evenly spaced. By evenly spaced multiple protruding pillars 211, a larger area of ​​hair can be processed simultaneously, improving the overall efficiency of the device and shortening the time required to dry hair.

[0045] like Figure 3 and Figure 5As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the heat insulation interlayer 3 includes a heat insulation interlayer body 31 and a flow guide 32. The heat insulation interlayer body 31 is sandwiched between the outer shell 1 and the air outlet shell 2. The heat insulation interlayer body 31 has a receiving cavity 301. The flow guide 32 is disposed on the heat insulation interlayer body 31 and located within the receiving cavity 301. The flow guide 32 cooperates with a slot on one side of the receiving cavity 301 to form a first air passage 302. By sandwiching the heat insulation interlayer body 31 between the outer shell 1 and the air outlet shell 2, heat transfer can be effectively blocked, reducing the surface temperature of the outer shell 1, preventing burns to the user, and improving the safety of the device. The flow guide 32 cooperates with a slot on one side of the receiving cavity 301 to form the first air passage 302, which can prevent the direct output of airflow from forming a strong impact that could damage the scalp or cause frizzy hair. Placing the flow guide 32 within the receiving cavity 301 allows for reasonable use of the internal space, making the device structure more compact, while ensuring unobstructed airflow channels.

[0046] like Figure 2 and Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the outer shell 1 is provided with a plurality of abutment protrusions 111, which are spaced apart around the inner sidewall of the mounting groove 102, and the end of the heat insulation interlayer body 31 away from the air outlet shell 2 abuts against the plurality of abutment protrusions 111. By abutting against the heat insulation interlayer body 31 with the abutment protrusions 111, the installation position of the heat insulation interlayer body 31 can be accurately positioned, ensuring a tighter fit between it and the outer shell 1 and the air outlet shell 2, improving assembly accuracy and efficiency. The plurality of abutment protrusions 111 spaced apart around the inner sidewall of the mounting groove 102 can provide uniform support force for the heat insulation interlayer body 31, preventing it from shifting or deforming due to uneven force, thereby enhancing the stability of the overall structure. At the same time, the arrangement of the plurality of abutment protrusions 111 can provide multi-point support for the heat insulation interlayer body 31, reducing vibration during equipment operation.

[0047] like Figure 2 and Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the heat insulation interlayer body 31 is provided with a plurality of protruding ribs 311, the plurality of protruding ribs 311 are spaced apart on the outer side wall of the receiving cavity 301, the plurality of protruding ribs 311 abut against the inner side wall of the mounting groove 102, and a first heat insulation cavity 103 is formed between the outer side wall of the receiving cavity 301 and the inner side wall of the mounting groove 102. By the plurality of protruding ribs 311 provided on the outer side wall of the receiving cavity 301 abut against the inner side wall of the mounting groove 102, a first heat insulation cavity 103 is formed between the heat insulation interlayer 3 and the outer shell 1, which can effectively block heat transfer, reduce the surface temperature of the outer shell 1, prevent users from being burned, and improve the safety of the equipment.

[0048] like Figure 2As shown, in addition to the features of the above embodiments, this embodiment further specifies that: at least a portion of the heat insulation interlayer 3 cooperates with the inner sidewall of the mounting groove 102 to form an abutment groove 304, and the air outlet housing 2 has an abutment portion 212 on the side facing the heat insulation interlayer 3, the abutment portion 212 extending into the abutment groove 304 and abutting against the heat insulation interlayer 3. By having at least a portion of the heat insulation interlayer 3 cooperate with the inner sidewall of the mounting groove 102 to form the abutment groove 304, and the abutment portion 212 on the air outlet housing 2 extending into the abutment groove 304 and abutting against the heat insulation interlayer 3, this design makes the connection between the outer shell 1, the heat insulation interlayer 3 and the air outlet housing 2 tighter, effectively enhancing the stability of the overall structure and preventing the overall structure from loosening or shifting due to vibration or external force.

[0049] like Figure 2 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: at least a portion of the abutment portion 212 and the air outlet housing 2 cooperate with the inner sidewall of the mounting groove 102 to form a second heat insulation cavity 105. By forming the second heat insulation cavity 105 through the cooperation between the abutment portion 212, at least a portion of the air outlet housing 2 and the inner sidewall of the mounting groove 102, heat transfer from hot air to the outer casing 1 is blocked, preventing users from being burned during use, and further improving the safety of the diffuser nozzle structure.

[0050] like Figure 3 , Figure 4 and Figure 7 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the edge of the mounting groove 102 forms a matching protrusion 112, and the air outlet housing 2 is provided with a matching groove 203, with the matching protrusion 112 fitting into the matching groove 203. By forming the matching protrusion 112 at the edge of the mounting groove 102, and ensuring that the matching protrusion 112 fits into the matching groove 203 of the air outlet housing 2, accurate alignment between the air outlet housing 2 and the outer housing 1 is ensured, improving installation accuracy and enhancing connection stability. The cooperative design of the matching protrusion 112 and the matching groove 203 makes the installation and disassembly between the air outlet housing 2 and the outer housing 1 more convenient, improving installation efficiency and reducing maintenance costs.

Furthermore, the cooperative design of the limiting protrusion 213 and the limiting groove 106 enables rapid assembly between the air outlet housing 2 and the outer housing 1, improving installation efficiency and reducing maintenance costs.

[0052] like Figure 4 and Figure 7 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the outer shell 1 is provided with a first fastening part 113, which is located on the inner sidewall of the mounting groove 102; the air outlet shell 2 is provided with a second fastening part 214 on the side facing the outer shell 1; the first fastening part 113 and the second fastening part 214 are fastened together.
