Description

Technical Field

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

[0002] Hair dryers are common household appliances, mainly used for drying and styling wet hair. Traditional hair dryers have a relatively small airflow, requiring users to spend a long time drying their hair. To address this, some hair dryers on the market have a dual airflow channel in the nozzle, with fans installed in each channel. The combined operation of the two fans increases the airflow. However, in actual use, because the outlets of the two airflow channels are adjacent, when only one fan is working, the airflow at the outlet of the working airflow channel can easily flow back into the non-working airflow channel, causing airflow circulation and affecting the airflow volume and temperature. Utility Model Content

[0003] Therefore, it is necessary to provide a nozzle assembly and a hair dryer to address the problem that in existing dual-airflow channel hair dryers, when only one fan is working, the airflow at the output port of the working airflow channel is easily backflowed into the non-working airflow channel, causing airflow circulation in the airflow channel and affecting the airflow volume and airflow temperature.

[0004] A nozzle assembly includes: a nozzle body having an air passage cavity, and a first opening on one side of the nozzle body connecting the air passage cavity to the outside; and a partition assembly disposed in the air passage cavity, the partition assembly dividing the air passage cavity into a first air outlet duct and a second air outlet duct, the first air outlet duct having a first inlet and a first outlet, the second air outlet duct having a second inlet and a second outlet, the first inlet and the second inlet being adjacent to each other, the first inlet and the second inlet being respectively connected to the air outlet end of the first airflow channel and the air outlet end of the second airflow channel of the blower body, and the first outlet and the second outlet being connected to the first opening.

[0005] This application provides a nozzle assembly. By setting a baffle assembly in the air passage cavity of the nozzle body, the air passage cavity can be divided into two independent first air outlet channels and second air outlet channels. The first inlet of the first air outlet channel and the second inlet of the second air outlet channel are arranged adjacent to each other and can be connected one-to-one with the air outlet ends of the first airflow channel and the second airflow channel in the hair dryer body. At the same time, the first outlet of the first air outlet channel and the second outlet of the second air outlet channel are both connected to the first opening of the nozzle body. Thus, when the first airflow channel and the second airflow channel of the hair dryer body emit air at the same time, the two airflow channels can be concentrated in the first opening to emit air outward, which greatly increases the air volume of the hair dryer and improves the drying efficiency. When only one airflow channel of the hair dryer body emits air, the baffle assembly in the nozzle assembly forms a barrier, and the path of the non-emitting airflow channel is extended through the first air outlet channel or the second air outlet channel. This increases the airflow resistance and can effectively prevent the airflow from flowing back into the non-emitting airflow channel, ensuring that the airflow will still be fully discharged from the first opening normally.

[0006] In one embodiment, the partition assembly includes a first partition and a second partition. The periphery of the first partition is adapted to and connected to the inner peripheral wall of the air passage cavity. The second partition is disposed in the middle of the first partition and located on the side near the first opening. The two side walls of the second partition are respectively connected to the inner wall of the air passage cavity. The first partition and the second partition cooperate to divide the air passage cavity into a first air outlet duct and a second air outlet duct. The first partition has a first inlet and a second inlet located on both sides of the second partition. By adopting the above structure, the air passage cavity is divided into a first air outlet duct and a second air outlet duct by the first partition and the second partition. The first partition has a first inlet and a second inlet. Therefore, when the nozzle assembly is assembled with the hair dryer body, compared with the second partition being directly connected to the air outlet end of the hair dryer body, the connection area is increased by the tight contact between the first partition and the air outlet end of the hair dryer body. This ensures that the airflow output from the first airflow channel and the airflow output from the second airflow channel of the hair dryer body fully enter the first air outlet duct and the second air outlet duct through the first inlet and the second inlet, respectively, forming an effective separation.

[0007] In one embodiment, the inner wall of the air passage cavity is provided with an annular step. The first partition includes a partition body and an annular support. The annular support protrudes from the periphery of the partition body, and the side of the annular support away from the partition body abuts against the annular step. The partition body is provided with a first inlet and a second inlet. The side of the second partition away from the first inlet is connected to the partition body. The abutting engagement between the annular support and the annular step provides a positioning function, facilitating the installation of the first partition. Simultaneously, when the nozzle assembly is assembled with the blower body, the annular step applies a certain pressure to the first partition through the annular support, ensuring a tight abutment between the first partition and the air outlet end of the blower body.

[0008] In one embodiment, the annular step mates with the inner wall of the air passage cavity to form an annular groove, and the annular bracket is fitted into the annular groove. The engagement of the annular bracket and the annular groove allows for better positioning and assembly of the first partition, ensuring that the first partition will not move or loosen during operation. Furthermore, it allows for a tight connection between the annular bracket and the inner wall of the air passage cavity, effectively preventing noise and energy loss caused by airflow passing through the gap between the two parts of the hair dryer body.

[0009] In one embodiment, the side wall of the nozzle body is provided with a snap-fit ​​interface communicating with the air passage cavity, and the outer wall of the annular bracket is provided with a snap-fit ​​block. The snap-fit ​​block engages with the snap-fit ​​interface to fix the annular bracket to the nozzle body. The snap-fit ​​between the snap-fit ​​interface and the snap-fit ​​block allows for quick connection and separation. This design facilitates the assembly and disassembly of the first partition and the nozzle body while ensuring stable installation.

[0010] In one embodiment, the side of the partition body away from the first partition mates with the inner wall of the air passage to form an installation space, which is used to fit and install with the air outlet end of the hair dryer body. By forming the installation space, the nozzle assembly can be positioned on the hair dryer body, thereby ensuring that the first and second inlets on the first partition can be smoothly aligned and connected with the air outlet ends of the first and second airflow channels, respectively.

[0011] In one embodiment, the first partition and the nozzle body are integrally formed. By adopting an integral molding process, the first partition and the nozzle body are integrated into a complete part, reducing assembly steps. There is no seam between the first partition and the nozzle body, effectively preventing the airflow output from the hair dryer body from flowing through the gap between them, which would cause noise and energy loss.

[0012] In one embodiment, the first partition has a slot, and the second partition is inserted into the slot. This structure improves the airtightness of the connection gap between the first and second partitions.

[0013] In one embodiment, the first partition has a mounting portion for mounting a magnetic element, which is used to fix the nozzle assembly to the air outlet of the hair dryer body.

[0014] In one embodiment, the mounting portion protrudes on the side of the partition body away from the first opening.

[0015] In one embodiment, the nozzle assembly further includes a housing, which is fitted onto the outer side wall of the nozzle body. By providing a housing fitted onto the outside of the nozzle body, a heat insulation effect can be achieved, effectively preventing the nozzle body from being directly touched by the user after being heated by hot air flow, thus avoiding accidents such as burns.

[0016] In one embodiment, a first snap-fit ​​portion is formed on the inner sidewall of the outer casing, and a second snap-fit ​​portion is formed on the outer sidewall of the nozzle body. The first snap-fit ​​portion and the second snap-fit ​​portion engage to connect the outer casing and the nozzle body. The snap-fit ​​between the first and second snap-fit ​​portions allows for quick connection and separation, facilitating both the assembly and disassembly of the outer casing and the nozzle body while ensuring stable installation.

[0017] In one embodiment, the cross-sectional areas of the first and second air outlet ducts gradually decrease towards the first opening. Besides being related to the duct length, the duct resistance is also affected by the duct cross-sectional area. By gradually narrowing the first and second air outlet ducts towards the first opening, the airflow velocity increases, further increasing the duct resistance of the non-exhausting airflow channels and significantly reducing the possibility of airflow flowing back into these channels.

[0018] In one embodiment, the lengths of the first and second air outlet ducts are L, where L ≥ 13.5 mm.

[0019] In one embodiment, the first input port and the second input port are symmetrically arranged.

[0020] A second aspect of this application provides a hair dryer.

[0021] A hair dryer includes: a hair dryer body, the hair dryer body including a nozzle section and a handle section connected to the nozzle section, the nozzle section having a first airflow channel and a second airflow channel, the first airflow channel having a first air inlet and a first air outlet, the second airflow channel having a second air inlet and a second air outlet, the first air outlet and the second air outlet being arranged adjacent to each other; a fan assembly, the fan assembly including a first fan disposed in the first airflow channel and a second fan disposed in the second airflow channel, the first fan being used to drive airflow to flow in from the first air inlet and out from the first air outlet, the second fan being used to drive airflow to flow in from the second air inlet and out from the second air outlet; and a nozzle assembly, the nozzle assembly being disposed at the air outlet end of the nozzle section, the first inlet communicating with the first air outlet, and the second inlet communicating with the second air outlet.

[0022] The hair dryer provided in the second aspect of this application, by employing the nozzle assembly of any of the aforementioned, allows the airflow output through the first and second airflow channels to be concentrated in the first opening and output outward when the first and second fans are working simultaneously, thus greatly increasing the airflow of the hair dryer. When only one of the fans in the airflow channels is working, since the first and second air inlets of the two airflow channels are adjacent and connected to the outside through the air inlet on the rear shell of the blower section, in order to avoid being affected by the negative pressure generated by the operation of the fan in the other airflow channel, the baffle assembly in the nozzle assembly forms a barrier, and the path of the non-airflow airflow channel is extended through the first or second airflow duct, thereby increasing the airflow resistance and effectively suppressing the backflow of airflow into the non-airflow airflow channel, ensuring that the airflow will still be discharged normally from the first opening.

[0023] In one embodiment, a magnetic suction assembly is further included. The magnetic suction assembly comprises a first magnetic element and a second magnetic element. The first magnetic element is disposed on the partition assembly, and the second magnetic element is disposed on the air outlet end of the air duct section. The second magnetic element and the first magnetic element are magnetically attracted to each other to position the nozzle assembly on the hair dryer body. The magnetic attraction between the first and second magnetic elements further strengthens the fixation between the atomizing body and the main unit.

[0024] In one embodiment, the first magnetic element is disposed in the mounting portion.

[0025] In one embodiment, the first airflow channel and the second airflow channel are arranged side by side. Attached Figure Description

[0038] 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.

[0039] 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.

[0040] The nozzle assembly of some embodiments of the present invention is described below with reference to the accompanying drawings.

[0041] like Figures 1 to 5 As shown, this embodiment discloses a nozzle assembly, including: a nozzle body 1, the nozzle body 1 having an air passage cavity 101, and a first opening 102 connecting the air passage cavity 101 to the outside on one side of the nozzle body 1; a partition assembly 2, the partition assembly 2 being disposed in the air passage cavity 101, the partition assembly 2 dividing the air passage cavity 101 into a first air outlet duct 1011 and a second air outlet duct 1012, the first air outlet duct 1011 having a first input port 10111 and a first output port 10112, the second air outlet duct 1012 having a second input port 10121 and a second output port 10122, the first input port 10111 and the second input port 10121 being arranged adjacent to each other, the first input port 10111 and the second input port 10121 being connected to the air outlet end of the first airflow channel and the air outlet end of the second airflow channel of the blower body respectively, and the first output port 10112 and the second output port 10122 being connected to the first opening 102.

[0042] This application provides a nozzle assembly. By providing a partition assembly 2 in the air passage cavity 101 of the nozzle body 1, the air passage cavity 101 can be divided into two independent first air outlet ducts 1011 and second air outlet ducts 1012. The first inlet 10111 of the first air outlet duct 1011 and the second inlet 10121 of the second air outlet duct 1012 are arranged adjacent to each other and can be connected one-to-one with the air outlet ends of the first airflow channel and the second airflow channel in the blower body. At the same time, the first outlet 10112 of the first air outlet duct 1011 and the second outlet 10122 of the second air outlet duct 1012 are both connected to the nozzle body. The first opening 102 is connected, so when the first airflow channel and the second airflow channel of the hair dryer body are emitting air at the same time, the two airflow channels can be concentrated in the first opening 102 to output outward, which greatly increases the air volume of the hair dryer and improves the drying efficiency. When only one airflow channel of the hair dryer body is emitting air, the baffle component 2 in the nozzle assembly forms a barrier, and the path of the non-airflow channel is extended through the first air outlet channel 1011 or the second air outlet channel 1012, thereby increasing the airflow resistance and effectively suppressing the backflow of airflow into the non-airflow channel, ensuring that the airflow will still be fully discharged from the first opening 102 normally.

[0043] like Figures 2 to 4As shown, in addition to the features of the above embodiments, this embodiment further defines that: the partition assembly 2 includes a first partition 21 and a second partition 22. The periphery of the first partition 21 is adapted to be connected to the inner peripheral wall of the air passage cavity 101. The second partition 22 is disposed in the middle of the first partition 21 and located on the side close to the first opening 102. The two side walls of the second partition 22 are respectively connected to the inner wall of the air passage cavity 101. The first partition 21 and the second partition 22 cooperate to divide the air passage cavity 101 to form a first air outlet duct 1011 and a second air outlet duct 1012. The first partition 21 is provided with a first inlet 10111 and a second inlet 10121 located on both sides of the second partition 22. By adopting the above structure, the air passage 101 is divided into a first air outlet duct 1011 and a second air outlet duct 1012 by the first partition 21 and the second partition 22. The first partition 21 is provided with a first inlet 10111 and a second inlet 10121. Thus, when the nozzle assembly is assembled with the hair dryer body, compared with the second partition 22 being directly connected to the air outlet end of the hair dryer body, the connection area is increased by the first partition 21 being tightly abutting against the air outlet end of the hair dryer body. This ensures that the airflow output from the first airflow channel and the airflow output from the second airflow channel of the hair dryer body can fully enter the first air outlet duct 10111 and the second air outlet duct 1012 through the first inlet 10111 and the second inlet 10121, respectively, forming an effective separation.

[0044] like Figure 2 and Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the inner wall of the air passage 101 is provided with an annular step 11; the first partition 21 includes a partition body 211 and an annular bracket 212; the annular bracket 212 protrudes from the periphery of the partition body 211; the side of the annular bracket 212 away from the partition body 211 abuts against the annular step 11; the partition body 211 is provided with a first inlet 10111 and a second inlet 10121; the side of the second partition 22 away from the first opening 102 is connected to the partition body 211. The abutting cooperation between the annular bracket 212 and the annular step 11 can form a positioning function, which facilitates the installation of the first partition 21; at the same time, when the nozzle assembly is assembled with the blower body, the annular step 11 can apply a certain pressure to the first partition 21 through the annular bracket 212, so that the first partition 21 can abut tightly against the air outlet end of the blower body.

[0045] like Figure 4As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the annular step 11 and the inner wall of the air passage cavity 101 cooperate to form an annular groove 103, and the annular bracket 212 is adapted to the annular groove 103. Through the cooperation of the annular bracket 212 and the annular groove 103, the positioning and assembly of the first partition 21 can be better realized, ensuring that the first partition 21 will not move or loosen during operation, and allowing the annular bracket 212 and the inner wall of the air passage cavity 101 to be tightly connected, effectively preventing the airflow output by the hair dryer body from flowing through the gap between the two, causing noise and loss.

[0046] like Figure 3 and Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the side wall of the nozzle body 1 is provided with a snap-fit ​​interface 104 that connects to the air cavity 101, and the outer wall of the annular bracket 212 is provided with a snap-fit ​​block 213. The snap-fit ​​block 213 engages with the snap-fit ​​interface 104 to fix the annular bracket 212 to the nozzle body 1. The snap-fit ​​between the snap-fit ​​interface 104 and the snap-fit ​​block 213 enables quick connection and separation. This design facilitates the assembly and disassembly of the first partition 21 and the nozzle body 1, while also ensuring stable installation.

[0047] like Figure 2 and Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the side of the partition body 211 away from the first partition 21 cooperates with the inner wall of the air passage 101 to form an installation space 105, which is used to be adapted to the air outlet end of the hair dryer body for installation. By forming the installation space 105, the installation of the nozzle assembly on the hair dryer body can be positioned, thereby ensuring that the first input port 10111 and the second input port 10121 on the first partition 21 can be smoothly aligned and connected with the air outlet ends of the first airflow channel and the second airflow channel, respectively.

[0048] like Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the first partition 21 and the nozzle body 1 are integrally formed. By adopting an integral molding process, the first partition 21 and the nozzle body 1 are integrated into a complete part, reducing assembly steps. There is no seam between the first partition 21 and the nozzle body 1, effectively preventing the airflow output from the hair dryer body from flowing through the gap between the two, thus avoiding noise and loss.

[0049] In addition to the features of the above embodiments, this embodiment further specifies that: the first partition 21 is provided with a slot, and the second partition 22 is inserted into the slot. By adopting the above structure, the airtightness of the connection gap between the first partition 21 and the second partition 22 can be improved.

[0050] like Figure 2 and Figure 3As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the first partition 21 is formed with a mounting portion 214, the mounting portion 214 is used to mount a magnetic member, and the magnetic member is used to fix the nozzle assembly to the air outlet end of the hair dryer body.

[0051] like Figure 2 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the mounting part 214 protrudes and is disposed on the side of the partition body 211 away from the first opening 102.

[0052] like Figures 2 to 4 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the nozzle assembly also includes a housing 3, which is sleeved on the outer side wall of the nozzle body 1. By providing the housing 3 sleeved on the outside of the nozzle body 1, a heat insulation effect can be formed, effectively preventing the nozzle body 1 from being directly touched by the user after being heated by hot air circulation, thus avoiding accidents such as burns to the user.

[0053] like Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: a first snap-fit ​​portion 31 is formed on the inner sidewall of the outer casing 3, and a second snap-fit ​​portion 106 is formed on the outer sidewall of the nozzle body 1. The first snap-fit ​​portion 31 and the second snap-fit ​​portion 106 are snap-fitted together to connect the outer casing 3 and the nozzle body 1. Through the snap-fit ​​between the first snap-fit ​​portion 31 and the second snap-fit ​​portion 106, quick connection and separation can be achieved. This design not only facilitates the assembly and disassembly of the outer casing 3 and the nozzle body 1, but also ensures stable installation.

[0054] like Figure 2 and Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the cross-sectional area of ​​the first air outlet duct 1011 and the cross-sectional area of ​​the second air outlet duct 1012 gradually decrease towards the first opening 102. The duct resistance is not only related to the duct length but also affected by the duct cross-sectional area. By making the first air outlet duct 1011 and the second air outlet duct 1012 gradually narrow towards the first opening 102, the airflow velocity will increase, further increasing the duct resistance of the non-air outlet airflow channel and greatly reducing the possibility of airflow flowing back into the non-air outlet airflow channel.

[0055] In addition to the features of the above embodiments, this embodiment further defines that the lengths of the first air outlet duct 1011 and the second air outlet duct 1012 are L, where L ≥ 13.5 mm.

[0056] like Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further defines that the first input port 10111 and the second input port 10121 are symmetrically arranged.

[0057] A second aspect of this application provides a hair dryer.

[0058] like Figure 1 and Figure 5 As shown, this embodiment discloses a hair dryer, including: a hair dryer body 200, the hair dryer body 200 including a nozzle portion 210 and a handle portion 220 connected to the nozzle portion 210, the nozzle portion 210 having a first airflow channel 202 and a second airflow channel 203, the first airflow channel 202 having a first air inlet 2021 and a first air outlet 2022, the second airflow channel 203 having a second air inlet 2031 and a second air outlet 2032, the first air outlet 2022 and the second air outlet 2032 being arranged adjacent to each other; and a fan assembly 300. The 0 includes a first fan disposed in the first airflow channel 202 and a second fan disposed in the second airflow channel 203. The first fan is used to drive airflow to flow in from the first air inlet 2021 and out from the first air outlet 2022, and the second fan is used to drive airflow to flow in from the second air inlet 2031 and out from the second air outlet 2032. The aforementioned nozzle assembly 100 is disposed at the air outlet end of the air duct section 210. The first inlet 10111 is connected to the first air outlet 2022, and the second inlet 10121 is connected to the second air outlet 2032.

[0059] The hair dryer provided in the second aspect of this application, by employing the nozzle assembly 100 of any of the aforementioned, when the first fan and the second fan are working simultaneously, the airflow output through the first airflow channel 202 and the second airflow channel 203 can be concentrated in the first opening 102 and output outward, thereby greatly increasing the air volume of the hair dryer; when only one of the fans in the airflow channel is working, since the first air inlet 2021 and the second air inlet 2031 of the two airflow channels are adjacent and are connected to the outside through the air inlet on the rear shell of the blower section 210, in order to avoid being affected by the negative pressure generated by the working of the fan in the other airflow channel, the baffle assembly 2 in the nozzle assembly 100 is used to form a barrier, and the path of the non-airflow airflow channel is extended through the first air outlet duct 1011 or the second air outlet duct 1012, thereby increasing the airflow resistance and effectively suppressing the backflow of airflow into the non-airflow airflow channel, ensuring that the airflow will still be discharged normally from the first opening 102.

[0060] In addition to the features of the above embodiments, this embodiment further includes a magnetic suction assembly, which comprises a first magnetic suction member and a second magnetic suction member. The first magnetic suction member is disposed on the partition assembly 2, and the second magnetic suction member is disposed on the air outlet end of the air duct section 210. The second magnetic suction member and the first magnetic suction member are magnetically attracted to each other to position the nozzle assembly 100 on the hair dryer body 200. The magnetic attraction between the first and second magnetic suction members further strengthens the fixation between the atomizing body and the main unit.

[0061] In addition to the features of the above embodiments, this embodiment further specifies that: the first magnetic member is disposed in the mounting portion 214.

[0062] like Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the first airflow channel 202 and the second airflow channel 203 are arranged side by side.

[0063] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent.

Therefore, the protection scope of this utility model patent should be determined by the appended claims.
