Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to a diffuser nozzle and a hair dryer. Background Art

[0002] At present, the hair dryers on the market generally come with a diffuser nozzle. After the diffuser nozzle is docked to the air outlet end of the hair dryer, the diffuser can guide the airflow to spread, so that the airflow can better cover the user's hair to improve the drying efficiency, and can also reduce the airflow speed, making the airflow act on the hair more gently. However, the current hair dryer has a relatively large air outlet noise, resulting in a poor user experience. Summary of the Utility Model

[0003] Based on this, in view of the problem that the air outlet noise is relatively large when some hair dryers on the market are equipped with a diffuser nozzle, resulting in a poor user experience, it is necessary to provide a diffuser nozzle and a hair dryer.

[0004] A diffuser nozzle includes: a housing, the housing is provided with a diffusion chamber; a noise reduction component, the noise reduction component includes a sound absorption net and a mounting seat, the mounting seat is detachably arranged on the housing, the mounting seat is located in the diffusion chamber, the housing or the mounting seat is provided with a first air inlet communicating with the outside and the diffusion chamber, the sound absorption net is arranged on the mounting seat, and at least part of the sound absorption net is arranged opposite to the first air inlet.

[0005] The present application provides a diffuser nozzle. The housing forms a diffusion chamber, and a noise reduction component including a sound absorption net and a mounting seat is arranged in the diffusion chamber. The sound absorption net is positioned on the mounting seat and fixed by the mounting seat. By using the quick connection between the mounting seat and the housing, the installation of the sound absorption net can be made more convenient, fast, stable and reliable. When the diffuser nozzle is assembled to the air outlet end of the hair dryer, the airflow will enter the diffusion chamber through the first air inlet. Specifically, the cross-sectional area of the diffusion chamber gradually increases along the air outlet direction, so that the air outlet area of the air outlet device is enlarged, and the airflow can better cover the user's hair. During the airflow movement, it will impact or pass through the sound absorption net. There are multiple densely arranged ventilation holes in the sound absorption net, and the air passing through the sound absorption net can reduce the flow rate and the noise, making the user experience better.

[0006] In one embodiment, the mounting base includes a base body and a connecting portion. The base body is adaptively mounted to the outer shell. The connecting portion is provided on the base body. The sound-absorbing net is provided on the connecting portion, and the first air inlet is provided on the connecting portion. By adopting the above structure, when assembling the noise reduction component, the installer can first position and mount the sound-absorbing net on the connecting portion, so that the sound-absorbing net can be quickly aligned with the first air inlet, and then use the cooperation between the base body and the outer shell to realize the overall fixation of the noise reduction component. Thereby, the connection difficulty between the sound-absorbing net and the outer shell can be reduced, which is beneficial to improving the assembly speed.

[0007] In one embodiment, the connecting portion is provided with a first connection hole, and the sound-absorbing net is provided with a second connection hole. The first connection hole and the second connection hole are connected by a fastener to cooperate with the sound-absorbing net and the connecting portion. The cooperation between the first connection hole and the second connection through the fastener can provide a stable connection for the sound-absorbing net and the connecting portion, and can ensure that the connected components will not be easily separated when accidentally stressed.

[0008] In one embodiment, the connecting portion includes a first positioning ring and a connecting column. The first positioning ring is provided on the base body. The first positioning ring encloses to form the first air inlet. The number of the connecting columns is multiple, and the multiple connecting columns are arranged at intervals along the circumferential direction of the first positioning ring. The connecting column is provided with the first connection hole. The first air inlet is formed by enclosing the first positioning ring. After the air flow enters the first air inlet, it flows along the length direction of the first positioning ring towards the sound-absorbing net, so as to better guide the air flow to ensure its full contact with the sound-absorbing net, thereby improving the sound insulation effect of the sound-absorbing net.

[0009] In one embodiment, the number of the second connection holes is the same as and corresponds to the number of the first connection holes one by one.

[0010] In one embodiment, the sound-absorbing net is located on one side of the first positioning ring close to the diffusion chamber. A wind guiding gap is formed between the sound-absorbing net and the top wall of the first positioning ring. The wind guiding gap communicates with the first air inlet and the diffusion chamber respectively. By forming the wind guiding gap, when the air flow collides with the sound-absorbing net and deflects, it can flow out through the wind guiding gap and enter the diffusion chamber. Thereby, while ensuring a certain noise reduction effect, the air volume loss can be reduced, avoiding too weak wind speed, and forming an annular wind guiding gap is also beneficial to the uniform diffusion of the air flow in the horizontal direction around.

[0011] In one embodiment, the base body includes a second positioning ring and a limiting rib. The second positioning ring is adaptively installed with the outer shell. The connecting portion is arranged inside the base body. The bottom of the second positioning ring abuts against the bottom of the outer shell. The limiting rib is arranged on the top of the second positioning ring. A clamping block is formed on the inner side wall of the diffusion cavity. The limiting rib is in clamping fit with the clamping block. By adopting the above connection structure, without using auxiliary tools such as screwdrivers, during installation, align the limiting rib with the clamping block and snap it in, then both sides of the base body can abut against the bottom of the outer shell and the limiting rib respectively, thereby enabling the base body to be positioned and installed on the outer shell and realizing the rapid assembly of the base body and the outer shell.

[0012] In one embodiment, a relief groove is provided on the top of the second positioning ring, and the limiting rib is located in the relief groove. By arranging the limiting rib in the relief groove, the structure of the base body can be made more compact, which is beneficial to reducing the volume of the diffusion nozzle. At the same time, the relief groove can serve as a relief space to facilitate the elastic deformation of the limiting rib during the clamping fit.

[0013] In one embodiment, a positioning block is formed on the inner side wall of the diffusion cavity, and a clamping groove is provided on the second positioning ring. The positioning block is inserted into the clamping groove. By adopting the above structure, the cooperation of the positioning block and the clamping groove can form a limiting effect, preventing the base body from sliding relative to the outer shell when the diffusion nozzle is subjected to an external collision, causing the limiting rib to disengage from the clamping block and resulting in the loosening and displacement of the noise reduction component.

[0014] In one embodiment, the outer shell is provided with a second air inlet. The mounting seat is adaptively installed with the second air inlet. The connecting portion extends to the outside through the first air inlet. The end of the connecting portion away from the sound absorption net is used for adaptively connecting with the air outlet end of the hair dryer. By adopting the above structure, the cooperation installation of the second air inlet and the mounting seat can further form a positioning effect, making the installation of the sound absorption component more convenient and fast.

[0015] In one embodiment, a positioning step is formed by the convex inner wall of the second air inlet. An annular groove is formed on the outer wall of the first positioning ring or the second positioning ring near the first air inlet. The positioning step is adaptively installed with the annular groove.

[0016] In one embodiment, the outer shell is provided with a second air inlet, and the first air inlet communicates with the outside through the second air inlet.

[0017] In one embodiment, the housing includes a first housing and a second housing. The first housing is disposed on the second housing. The first housing and the second housing enclose to form the diffusion chamber. The second housing is provided with the first air inlet. On a side of the first housing away from the diffusion chamber, there are a plurality of first air outlet columns and a plurality of second air outlet columns. The plurality of first air outlet columns are arranged around the center of the first housing and surround the plurality of second air outlet columns. The first air outlet column is provided with a first air outlet opening towards the center of the first housing. The second air outlet column is provided with a plurality of second air outlet openings arranged around the center of the second air outlet column. Both the first air outlet and the second air outlet are communicated with the diffusion chamber. By adopting the above structure, the air flow in the diffusion chamber can be output to the outside through the first air outlet and the second air outlet respectively. The first air outlet of the first air outlet column is arranged towards the center of the first housing. The second air outlet column is located on a side of the first air outlet column close to the center of the first housing and a plurality of second air outlet openings are arranged around its center. Thereby, the air flow can be more concentrated in the area covered by the first air outlet column and the second air outlet column, and the air flow in this area is more uniform, ensuring that the hair is fully heated. And when the user stirs the hair with the first air outlet column and the second air outlet column, the hair roots can be more fully contacted with the air flow, which can further improve the hair drying efficiency.

[0018] In one embodiment, a groove is formed by recessing on a side of the first housing away from the first air inlet. The first air outlet column and the second air outlet column are located in the groove. By forming the groove, it is convenient to position the hair in the groove, so that the hair can be more stably contacted with the air flow.

[0019] In one embodiment, the first housing is formed with a first clamping portion, and the second housing is formed with a second clamping portion. The first clamping portion can be clamped and matched with the second clamping portion.

[0020] In one embodiment, a plurality of air outlet holes communicated with the diffusion chamber are provided on a side of the housing away from the first air inlet. Specifically, the first housing is provided with a plurality of air outlet holes communicated with the diffusion chamber. Through this design, the positions of the diffusion nozzle except for the positions of the first air outlet column and the second air outlet column can also blow air, thereby making the air outlet more uniform and being beneficial to improving the hair drying efficiency.

[0021] In one embodiment, a magnetic member is further included. The magnetic member is disposed on the housing or the mounting base. The magnetic member is used to connect the air outlet end of the hair dryer. By utilizing the magnetic attraction of the magnetic member, the diffusion nozzle can be quickly positioned and connected to the air outlet end of the hair dryer, achieving the purpose of quick assembly and disassembly.

[0022] In one embodiment, the end of the connection portion away from the silencing net is provided with a mounting groove, and the magnetic member is adapted to be mounted in the mounting groove. By adopting the above structure, the positioning and assembly of the magnetic member can be facilitated, and the hidden setting of the magnetic member can be realized, so that the appearance of the diffuser nozzle is improved.

When the diffuser nozzle is assembled to the air outlet end of the hair dryer, the air flow will enter the diffusion chamber 101 through the first air inlet 201. Specifically, the cross-sectional area of the diffusion chamber 101 gradually increases along the air outlet direction, thereby expanding the air outlet area of the air outlet device and enabling the air flow to better cover the user's hair. During the air flow process, it will hit or pass through the sound-absorbing net 21. There are multiple densely arranged ventilation holes in the sound-absorbing net 21. The air passing through the sound-absorbing net 21 can play the role of reducing the flow rate and reducing the noise, making the user experience better.

[0040] As Figure 1 and Figure 2As shown, in addition to the features of the above embodiments, this embodiment further defines that: the mounting base 22 includes a base body 221 and a connecting portion 222. The base body 221 is adaptively mounted to the outer shell 1. The connecting portion 222 is provided on the base body 221. The sound-absorbing net 21 is provided on the connecting portion 222, and the connecting portion 222 is provided with a first air inlet 201. By adopting the above structure, when assembling the noise reduction assembly 2, the installer can first position and mount the sound-absorbing net 21 on the connecting portion 222, so that the sound-absorbing net 21 can be quickly aligned with the first air inlet 201, and then use the cooperation between the base body 221 and the outer shell 1 to realize the overall fixation of the noise reduction assembly 2. Thereby, the connection difficulty between the sound-absorbing net 21 and the outer shell 1 can be reduced, which is beneficial to improving the assembly speed.

[0042] As Figure 2 and Figure 3 shown, in addition to the features of the above embodiments, this embodiment further defines that: the connecting portion 222 includes a first positioning ring 2221 and a connecting column 2222. The first positioning ring 2221 is provided on the base body 221. The first positioning ring 2221 encloses to form the first air inlet 201. The number of connecting columns 2222 is multiple, and the multiple connecting columns 2222 are arranged at intervals along the circumferential direction of the first positioning ring 2221. The connecting column 2222 is provided with the first connection hole 202. The first air inlet 201 is formed by enclosing the first positioning ring 2221. After the air flow enters the first air inlet 201, it flows along the length direction of the first positioning ring 2221 towards the sound-absorbing net 21, so as to better guide the air flow to ensure that it is in full contact with the sound-absorbing net 21. Thereby, the sound insulation effect of the sound-absorbing net 21 is improved.

[0043] As Figure 3 shown, in addition to the features of the above embodiments, this embodiment further defines that: the number of the second connection holes 203 is the same as that of the first connection holes 202 and they correspond one by one.
