Technical Field
[0001] This utility model relates to the technical field of household appliances, and in particular to a hair dryer. Background Technology
[0002] Hair dryers are a common tool for hair care, widely used because they can dry and style hair.
[0003] As a key accessory for hair dryers, the nozzle can be adjusted to suit specific working modes within a certain range, thereby changing or optimizing the airflow speed, direction, and range of the airflow to meet the needs of different users.
[0004] Most existing hair dryers have a constant air outlet gap. Therefore, to meet different usage requirements such as air pressure, air speed, temperature, and whether to concentrate or amplify airflow, different specifications of air outlets are usually replaced. This results in a hair dryer having multiple air outlets. However, only one air outlet is used at a time, and the remaining unused air outlets need to be stored to avoid loss. In addition, when it is necessary to replace the air outlet, the air outlet in use must be removed and another new air outlet must be selected to achieve the purpose of adjusting air pressure and air speed or switching between concentrating and amplifying airflow. Because there are multiple air outlets, it causes trouble to select and install them during use, and the remaining unused air outlets also present a storage problem. Utility Model Content
[0005] The purpose of this invention is to provide a hair dryer that solves the problem of inconvenient operation during use and storage caused by multiple air outlets, avoids the problem of cumbersome operation during use and storage caused by switching multiple air outlets, and improves the convenience of switching between the airflow expansion mode and the airflow concentration mode.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a hair dryer, including a head and a handle, the front end of the head is provided with an air outlet and a detachably connected air nozzle, the air nozzle having a first mounting end, a second mounting end, and mutually independent air gathering channels and air expanding channels, the first mounting end of the air nozzle being mounted on the head, the air outlet being connected only to the air gathering channel, the second mounting end of the air nozzle being mounted on the head, the air outlet being connected only to the air expanding channel, the first mounting end and the second mounting end being located at opposite ends of the air nozzle.
[0007] After adopting the above technical solution, this utility model has the following advantages: the handle design makes it easy for users to hold the hair dryer for blow-drying or styling; the detachable nozzle at the front of the head makes it easy to remove the nozzle from the front of the head for adjustment or replacement; the independent design of the air-gathering channel and the air-expanding channel of the nozzle avoids mutual interference during ventilation, ensuring functional independence; when the first mounting end of the nozzle is connected to the head, the air outlet is connected to the air-gathering channel, making the hair dryer in a concentrated air state, allowing users to use a higher air speed; the second mounting end of the nozzle... When the end is connected to the head, the air outlet is connected to the air amplification channel, making the hair dryer in amplification mode, which is convenient for users to use at a lower wind speed. When the user is using the hair dryer and needs to switch from concentrated air mode to amplification mode or vice versa, simply remove the same air outlet from the front of the head, swap the front and back positions of the first and second mounting ends, and then reinstall the air outlet. This will switch the hair dryer between concentrated air mode and amplification mode, reducing the difficulty of switching between the two modes. After switching, there is no need to replace the other air outlet, thus avoiding the trouble of using, selecting, and storing multiple air outlets.
[0008] Furthermore, the air expansion channel is arranged around the outer periphery of the air gathering channel, and the second mounting end of the air outlet is installed and connected to the machine head, so that the air gathering channel is aligned and connected with the air outlet and the air expansion channel is offset from the air outlet. The first mounting end of the air outlet is installed and connected to the machine head, so that the air gathering channel is offset from the air outlet and the air expansion channel is aligned and connected with the air outlet.
[0009] Using the aforementioned technical solution, the air expansion channel is arranged around the outer periphery of the air gathering channel, making the air expansion and air gathering effects of the blower significantly different. The second mounting end of the air outlet is installed and connected to the head unit, aligning and connecting the air gathering channel with the air outlet, and offsetting the air expansion channel from the air outlet, ensuring that only the air gathering channel blows air in the air gathering state. The first mounting end of the air outlet is installed and connected to the head unit, offsetting the air gathering channel from the air outlet, and aligning and connecting the air expansion channel with the air outlet, ensuring that only the air expansion channel blows air in the air expansion state, thus improving the independence of the air gathering channel and the air expansion channel.
[0010] Furthermore, the air outlet includes an inner ring and an outer ring, with an air-gathering channel passing through the inner ring and the outer ring fitted around the outer periphery of the inner ring, forming an annular air-expanding channel between the outer ring and the inner ring.
[0011] Using the aforementioned technical solution, an air outlet is provided at the front end of the blower head. The air outlet nozzle is designed in the form of an inner ring and an outer ring. The air-gathering channel runs through the inner ring, and an annular air-expanding channel is formed between the inner and outer rings. When the blower needs to be used in air-gathering mode, the second mounting end of the air outlet nozzle is installed at the front end of the blower head, and the airflow is blown out from the air-gathering channel, making it convenient for the user to use the blower in air-gathering mode directly. When it is necessary to switch to air-expanding mode, the air outlet nozzle is removed from the front end of the blower head, and the first and second mounting ends of the air outlet nozzle are flipped over. The first mounting end of the air outlet nozzle is then installed at the front end of the blower head, and the airflow enters the air-expanding channel and is blown out from the air-expanding channel, making it convenient for the user to use the blower in air-expanding mode directly. The air-expanding channel is designed in an annular shape to improve the air-expanding effect during the blowing process.
[0012] Furthermore, both the air-gathering channel and the air-expanding channel have a flared end and a constricted end. The flared ends of both the air-gathering channel and the air-expanding channel are located at the second mounting end of the air outlet, and the constricted ends of both the air-gathering channel and the air-expanding channel are located at the first mounting end of the air outlet.
[0013] Using the aforementioned technical solution, both the air-gathering channel and the air-expanding channel have flared and constricted ends, ensuring that after the first and second mounting ends of the air outlet are swapped, both the air-gathering channel ventilation and the air-expanding channel ventilation can achieve the corresponding air-gathering or air-expanding effect. The flared ends are all located at the second mounting end of the air outlet, ensuring that the blower enters the air-gathering state after the second mounting end is connected to the head unit. The constricted ends are all located at the first mounting end of the air outlet, ensuring that the blower enters the air-expanding state after the first mounting end is connected to the head unit.
[0014] Furthermore, both the air-gathering channel and the air-expanding channel are enlarged from the first installation end to the second installation end, and the flared end of the air-gathering channel and the constricted end of the air-expanding channel are adapted to the air outlet.
[0015] Using the aforementioned technical solution, the expansion from the first mounting end to the second mounting end ensures that the blower is in an expanding state when the first mounting end of the air outlet is connected to the head, and in an air concentrating state when the second mounting end is connected to the head. The flared end and the constricted end of the air concentrating channel are both adapted to the air outlet. When airflow enters the air concentrating channel, the airflow flows from the flared end to the constricted end, ensuring the air concentrating effect of the air concentrating channel. When airflow enters the air expansion channel, the airflow flows from the constricted end to the flared end, ensuring the air expansion effect of the air expansion channel.
[0016] Furthermore, the air outlet includes an inner ring body, the inner hole of which forms an air-gathering channel. The cross-sectional area of the air-gathering channel gradually decreases from the second mounting end to the first mounting end, so that the air-gathering channel can gather air in the direction from the second mounting end to the first mounting end.
[0017] By adopting the aforementioned technical solution, an air-gathering channel is formed through the inner hole of the inner ring body, and the cross-sectional area gradually decreases from the second mounting end to the first mounting end, ensuring the air-gathering effect of the blower when the airflow is from the second mounting end to the first mounting end.
[0018] Furthermore, the air outlet includes an inner ring body and an outer ring body. The outer ring body is fitted around the outer periphery of the inner ring body. An air expansion channel is formed between the outer periphery of the inner ring body and the inner wall of the outer ring body. The outer diameter of the inner ring body and the inner diameter of the outer ring body gradually increase from the first mounting end to the second mounting end, so that the air expansion channel has an air expansion function in the direction from the first mounting end to the second mounting end.
[0019] Using the aforementioned technical solution, the air outlet is configured as an inner ring and an outer ring. An air-expanding channel is formed between the outer peripheral side of the inner ring and the inner wall of the outer ring to ensure the uniformity of airflow distribution on the outer peripheral side of the inner ring. The outer diameter of the inner ring and the inner diameter of the outer ring gradually increase from the first mounting end to the second mounting end to ensure the air-expanding effect of the blower when the airflow is blown out from the first mounting end to the second mounting end.
[0020] Furthermore, the front end of the machine head is provided with a panel, the air outlet is located on the panel, and the end face of the inner ring body is attached to the panel to separate the air gathering channel and the air expanding channel.
[0021] By employing the aforementioned technical solution, the end face of the inner ring is fitted to the panel, ensuring that the air-gathering channel and the air-expanding channel are separated, thereby ensuring that the air-gathering channel and the air-expanding channel blow air independently. In addition, the fitting of the end face of the inner ring to the panel avoids the possibility of the air outlet shaking during use, improving the stability of the air outlet during use.
[0022] Furthermore, the panel is provided with a rearward recessed groove, and the inner ring is provided with a positioning rib that is inserted into the groove to cooperate when the first mounting end of the air outlet is installed on the machine head; and / or, the first mounting end of the outer ring is provided with a mating ring on the outer periphery of the air expansion channel, and the mating ring is in contact with the panel when the first mounting end of the air outlet is installed and connected to the machine head.
[0023] By adopting the aforementioned technical solution, the stability of the air outlet is improved by inserting the positioning rib into the groove for engagement. The plug-in method simplifies the installation and disassembly of the air outlet, thereby facilitating the switching between the blower's air-concentrating and air-expanding states. When the first mounting end of the air outlet is installed at the front of the head, the engagement ring fits snugly against the panel, improving the stability of the air outlet after installation. In addition, the fit between the engagement ring and the panel also improves the sealing effect between the first mounting end of the air outlet and the front of the body, reducing the possibility of airflow flowing between the first mounting end of the air outlet and the panel, which could affect the stability of the air outlet after installation.
[0024] Furthermore, both the first and second mounting ends of the air outlet are provided with collars, which are fitted onto the outer periphery of the front end of the machine head with an interference fit or snap-fit fixation; or, the air outlet is magnetically attracted to the machine head, with one end of the air outlet and one end of the front end of the machine head provided with a magnet, and the other provided with a ferromagnetic body attracted to the magnet.
[0025] By employing the aforementioned technical solutions, the stability of the air outlet after installation is improved by providing collars at both the first and second mounting ends of the nozzle, and then using an interference fit between the collars and the outer periphery of the front end of the blower head. Alternatively, the collars can be fixed to the front end of the blower head with snap fasteners, further enhancing the stability of the air outlet after installation and preventing it from falling off during use. Alternatively, when installing the air outlet, the attraction between a magnet and a ferromagnetic body simplifies the installation process and ensures stable installation. This facilitates switching between the first or second mounting end of the air outlet and the front end of the blower head, allowing for easy switching between the blower's amplification and concentration modes by changing the front and rear ends of the air outlet.

[0034] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be selected to be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.
[0035] like Figures 1 to 5 As shown, this utility model provides a hair dryer, including a head 1 and a handle 2. The handle 2 is designed for easy gripping by the user for drying hair or styling. The front end of the head 1 has an air outlet 11 and a detachable nozzle 3. The detachable connection facilitates the removal or installation of the nozzle 3. Specifically, as shown... Figure 3 As shown, the air outlet 3 has a first mounting end 31, a second mounting end 32, and independent air-gathering channels 331 and air-expanding channels 341, as follows: Figure 3 As shown, the second mounting end 32 of the air outlet 3 is installed at the front end of the head 1. The air outlet 11 is only connected to the air concentrating channel 331, so that the air blower enters the air concentrating state. If it is necessary to switch the air concentrating state to the air amplification state, the same air outlet 3 is removed from the front end of the head 1, and the front and rear positions of the first mounting end 31 and the second mounting end 32 of the air outlet 3 are swapped. That is to say, if Figure 3 and Figure 4As shown, the first mounting end 31 of the air outlet 3 is installed at the front end of the head 1, and the air outlet 11 is only connected to the air expansion channel 341, so that the air blower enters the air expansion state. It should be noted that the first mounting end 31 and the second mounting end 32 are located at opposite ends of the air outlet 3. Therefore, when it is necessary to switch the air blower's air concentration state or air expansion state, the positions of the first mounting end 31 and the second mounting end 32 of the same air outlet 3 can be reversed in the front-back direction to switch the air blower's air expansion state and air concentration state, reducing the difficulty of switching between the air concentration state and the air expansion state. Moreover, no other air outlet 3 needs to be replaced before and after switching, thus avoiding the problem of using and storing multiple air outlet 3. In addition, the air concentration channel 331 and the air expansion channel 341 are independent of each other, avoiding the air outlet 331 and the air expansion channel 341 from emitting air at the same time, which would affect the heat dissipation effect of the air outlet 3.
[0036] Specifically, such as Figure 3 and Figure 4 As shown, the air expansion channel 341 is arranged around the outer periphery of the air concentration channel 331, so that the diameter of the air expansion channel 341 is larger than the diameter of the air concentration channel 331, ensuring the air expansion and concentration effects of the blower and the uniformity of the air output from the air concentration channel 331 and the air expansion channel 341; the second mounting end 32 of the air outlet 3 is installed and connected to the head 1, so that the air concentration channel 331 is aligned and connected with the air outlet 11, and the air expansion channel 341 is staggered from the air outlet 11, ensuring that only the air concentration channel 331 blows air in the air concentration state; the first mounting end 31 of the air outlet 3 is installed and connected to the head 1, so that the air concentration channel 331 is staggered from the air outlet 11, and the air expansion channel 341 is aligned and connected with the air outlet 11, ensuring that only the air expansion channel 341 is connected to the air outlet 11, ensuring that only the air expansion channel 341 blows air in the air expansion state; improving the independence of the air concentration channel 331 and the air expansion channel 341.
[0037] In this embodiment, as Figure 3 As shown, the air outlet 3 is configured to include an inner ring 33 and an outer ring 34. The air-gathering channel 331 passes through the inner ring 33, and the outer ring 34 is fitted around the outer periphery of the inner ring 33. An annular air-expanding channel 341 is formed between the outer ring 34 and the inner ring 33. When the blower needs to be used in the air-gathering state, the second mounting end 32 of the air outlet 3 is installed at the front end of the head 1, and the airflow is blown out from the air-gathering channel 331, allowing the user to directly use the blower in the air-gathering state. When the blower needs to be switched to the air-expanding state, the air outlet 3 is removed from the front end of the head 1, and the first mounting end 31 and the second mounting end 32 of the air outlet 3 are flipped over. The first mounting end 31 of the air outlet 3 is then installed at the front end of the head 1, and the airflow enters the air-expanding channel 341 and is blown out from the air-expanding channel 341, allowing the user to directly use the blower in the air-expanding state. The air-expanding channel 341 is annular, which improves the air-expanding effect during the blowing process and the uniformity of the airflow distribution during the airflow process.
[0038] To ensure the wind gathering and amplification effects of the wind gathering channel 331 and the wind amplification channel 341, such as Figure 3 and Figure 4 As shown, both the air-gathering channel 331 and the air-expanding channel 341 have an flared end 35 and a constricted end 36. The flared ends 35 of the air-gathering channel 331 and the air-expanding channel 341 are located at the second mounting end 32 of the air outlet 3, and the constricted ends 36 of the air-gathering channel 331 and the air-expanding channel 341 are located at the first mounting end 31 of the air outlet 3. After the first mounting end 31 is connected to the front end of the head 1, the constricted end 36 of the air-gathering channel 331 or the air-expanding channel 341 is connected to the air outlet 11, and the blower is in the air-gathering state; otherwise, the blower is in the air-expanding state.
[0039] Furthermore, such as Figure 4 As shown, both the air-gathering channel 331 and the air-expanding channel 341 are enlarged from the first mounting end 31 to the second mounting end 32, ensuring that the blower is in an expanded state after the first end of the air outlet 3 is installed. The flared end 35 of the air-gathering channel 331 and the constricted end 36 of the air-expanding channel 341 are adapted to the air outlet 11. When the airflow enters the air-gathering channel 331, the airflow flows from the flared end 35 to the constricted end 36, ensuring the air-gathering effect of the air-gathering channel 331. When the airflow enters the air-expanding channel 341, the airflow flows from the constricted end 36 to the flared end 35, ensuring the air-expanding effect of the air-expanding channel 341.
[0040] In another embodiment, such as Figure 3 As shown, the air outlet 3 includes an inner ring body 33, and the inner hole of the inner ring body 33 forms an air-gathering channel 331. After the second mounting end 32 of the air outlet 3 is installed at the front end of the head 1, the cross-sectional area of the air-gathering channel 331 gradually decreases from the second mounting end 32 to the first mounting end 31. The airflow flows along the inner wall of the inner ring body 33, so that the airflow from the second mounting end 32 to the first mounting end 31 in the air-gathering channel 331 plays a role in gathering airflow, ensuring that the airflow blown out from the air-gathering channel 331 plays a role in gathering airflow.
[0041] To ensure the wind gathering and amplification effects of the wind gathering channel 331 and the wind amplification channel 341, such as Figure 4As shown, the air outlet 3 includes an inner ring body 33 and an outer ring body 34. The outer ring body 34 is fitted around the outer periphery of the inner ring body 33. An air-expanding channel 341 is formed between the outer periphery of the inner ring body 33 and the inner wall of the outer ring body 34. The outer diameter of the inner ring body 33 and the inner diameter of the outer ring body 34 gradually increase from the first mounting end 31 to the second mounting end 32, so that the air-expanding channel 341 has an air-expanding effect from the first mounting end 31 to the second mounting end 32. After the first mounting end 31 is connected to the front end of the head unit 1, the airflow enters the air-gathering channel 331 and flows along the outer wall of the inner ring body 33 and the inner wall of the outer ring body 34, ensuring that the airflow enters the air-expanding channel 341 and is blown out from the first mounting end 31 to the second mounting end 32, thus having an air-expanding effect; conversely, it has an air-gathering effect.
[0042] Specifically, such as Figure 4 and Figure 5 As shown, the front end of the blower head 1 is provided with a panel 12, and the air outlet 11 is provided on the panel 12. The end face of the inner ring body 33 is attached to the panel 12 to separate the air gathering channel 331 from the air expanding channel 341, thereby ensuring that the air gathering channel 331 and the air expanding channel 341 are ventilated independently to achieve the air gathering state or the air expanding state of the blower. In addition, after the end face of the inner ring body 33 is attached to the panel 12, the gap between the end face of the inner ring body 33 and the panel 12 is reduced, reducing the airflow from flowing between the front side of the panel 12 of the blower head 1 and the rear side of the inner ring body 33, which would affect the stability of the air outlet 3.
[0043] In this embodiment, as Figure 5 As shown, to improve the stability of the air outlet 3 after installation in the amplification state, the panel 12 is provided with a recessed groove 121, and the first mounting end 31 of the inner ring 33 is provided with a positioning rib 332. When the first mounting end 31 of the air outlet 3 is installed on the head 1, the positioning rib 332 is inserted into the groove 121 and cooperates with the groove 121. Through the insertion and cooperation of the positioning rib 332 and the groove 121, the stability of the air outlet 3 is improved, and the insertion method simplifies the installation and disassembly of the air outlet 3, thereby facilitating the switching between the air blower's concentrating state and the amplification state.
[0044] To further improve the stability of the air outlet nozzle 3 after installation under expanded airflow conditions, such as Figure 3 As shown, the first mounting end 31 of the outer ring 34 is provided with a mating ring 342. The mating ring 342 is located on the outer periphery of the air expansion channel 341. When the first mounting end 31 of the air outlet 3 is installed at the front end of the head 1, the mating ring 342 fits against the panel 12, further improving the stability of the air outlet 3 after installation. Moreover, the fit between the mating ring 342 and the panel 12 improves the sealing effect when the first mounting end 31 of the air outlet 3 is installed at the front end of the head 1, reducing the possibility of airflow flowing between the first mounting end 31 of the air outlet 3 and the panel 12, thus affecting the stability of the air outlet 3 after installation.
[0045] To prevent the inner ring 33 and outer ring 34 from separating, the air expansion channel 341 is provided with a connecting rib. The connecting rib extends radially along the inner ring 33 and connects the outer ring 34 and the inner ring 33. After the airflow enters the air gathering channel 331 or the air expansion channel 341, the connecting rib keeps the inner ring 33 and outer ring 34 in a relatively stationary state, preventing the possibility of the inner ring 33 and outer ring 34 separating during the use of the blower. This ensures that the gap size of the air expansion channel 341 is stable.
[0046] To facilitate the installation and removal of the air outlet 3, the air outlet 3 is magnetically attached to the front end of the head unit 1. Specifically, both the first mounting end 31 and the second mounting end 32 of the air outlet 3 are equipped with magnets, and the front end of the head unit 1 is equipped with a ferromagnetic body. When installing the air outlet 3, the magnets and the ferromagnetic body attract each other to stabilize the air outlet 3. When it is necessary to remove the air outlet 3, the air outlet 3 can be pulled directly away from the front end of the head unit 1 to remove it from the ferromagnetic body, thus achieving the removal of the air outlet 3; simplifying the installation and removal of the air outlet 3. In another embodiment, the magnets can be located at the front end of the head unit 1, and the ferromagnetic body can be located at the first mounting end 31 and the second mounting end 32 of the air outlet 3. Similarly, the magnets and the ferromagnetic body attract each other to stabilize the air outlet 3, also achieving the same effect of simplifying the installation and removal of the air outlet 3.
[0047] To improve the stability of the air outlet 3 after it is installed at the front end of the head unit 1, such as Figure 3 and Figure 4 As shown, both the first mounting end 31 and the second mounting end 32 of the air outlet 3 are provided with a collar 343. When the air outlet 3 is configured to include an inner ring body 33 and an outer ring body 34, the collar 343 is installed on the first mounting end 31 and the second mounting end 32 of the outer ring body 34. When installing the air outlet 3, regardless of whether the first mounting end 31 or the second mounting end 32 of the air outlet 3 is connected to the head 1, the collar 343 is sleeved on the outer periphery of the front end of the head 1, and the inner peripheral wall of the collar 343 is interference-fitted with the outer peripheral wall of the front end of the head 1. The collar 343 increases the contact range between the air outlet 3 and the front end of the head 1, improves the stability of the air outlet 3 after installation, and the interference fit avoids the gap between the collar 343 and the front end of the head 1, which would cause shaking, further improving the stability of the air outlet 3 after installation. To further improve the stability of the air outlet 3 after installation, the collar 343 can also be fixed to the outer periphery of the front end of the head 1 by a snap fastener; the snap fastener method avoids the possibility of the collar 343 detaching from the front end of the head 1, further improving the stability of the air outlet 3 after installation.
[0048] In addition to the preferred embodiments described above, there are other embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection claimed by this utility model.
