Description

Technical Field

[0001] This invention relates to the field of hair dryer technology, and in particular to air guide components and hair dryers. Background Technology

[0002] Household hair dryers are mainly used for drying and styling hair. Hair dryers are generally driven by a motor to rotate the rotor and make the fan blades rotate, so that air is drawn in from the air inlet. The resulting centrifugal airflow is then blown out from the nozzle. Currently, most hair dryers on the market are T-shaped, which uses dual air ducts to supply air and increase the air volume. However, the internal air ducts of current hair dryers are very inefficient because air enters the shell freely under the negative pressure created by the fan, and the airflow crashes against the inner wall of the shell in a very chaotic manner, resulting in great losses. Summary of the Invention

[0003] Therefore, it is necessary to provide an air guide component and a hair dryer to address the problem of airflow loss caused by the impact of airflow on the inner wall of the casing during the internal airflow process.

[0004] An air guiding assembly includes a protective shell with a receiving cavity and an air inlet communicating with the receiving cavity, the air inlet being located on a side wall of the protective shell; an air outlet disposed on the protective shell, forming an air outlet between the air outlet and the protective shell, or having an air outlet on the air outlet, the air outlet communicating with the receiving cavity, the air outlet being located at an end of the protective shell or the air outlet; and an air divider disposed on the air outlet and / or the protective shell, the air divider extending in the same direction as the air inlet extending towards the air outlet, forming an air passage between the air inlet and the air outlet, the air divider dividing at least a portion of the air passage into multiple channels.

[0005] The air guiding assembly disclosed in this application forms a receiving cavity within a protective housing, with an air inlet communicating with the receiving cavity. For example, when outside air is pressurized, it enters through the air inlet. After entering the receiving cavity, because the air distributor and air outlet are positioned opposite each other, the pressurized air is transported towards the air distributor. After passing through the air distributor, the air is diverted and guided through multiple channels formed by the air distributor. Guided by the air distributor, the air is directed from the air inlet towards the air outlet. The air distributor design avoids pressurized air input from the side of the protective housing from being directly blown towards the top wall, thus preventing airflow loss and effectively improving the efficiency of airflow utilization. By guiding the input pressurized air through the air distributor, the airflow distribution becomes more uniform.

[0006] In one embodiment, at least a portion of the air distributor is plate-shaped, and the plate-shaped portion of the air distributor divides a portion of the air passage into multiple channels. By making a portion of the air distributor plate-shaped, the air passage can be better divided using the plate structure, and the plate structure occupies a smaller area, thus reducing obstruction to pressurized air. This avoids the problem of small channels after division affecting usability. Furthermore, the air passage can be divided into different numbers, such as two, three, four, five, six, seven, eight, or nine channels, as needed.

[0007] In one embodiment, the air distributor divides a portion of the air passage into two air distribution channels. The air outlet is annular, with the portion of the air outlet near the sidewall where the air inlet is located connected to one of the air distribution channels and the air inlet in sequence. The portion of the air outlet away from the sidewall where the air inlet is located is connected to the other air distribution channel and the air inlet in sequence. Dividing a portion of the air passage into two air distribution channels allows for better guidance of the airflow, preventing excessive turbulence generated within the protective housing by the air entering through the air inlet, and enabling more stable and rational airflow utilization.

[0008] In one embodiment, the plate-shaped portion of the air distributor is disposed opposite to the air inlet to separate the fluid input from the air inlet into at least two streams. By distributing the plate-shaped portion of the air distributor opposite to the air inlet, pressurized air can be directly guided upon entry, reducing losses in the channel and effectively improving air delivery efficiency.

[0009] In one embodiment, the plate-shaped portion of the air distributor has a curved cross-section. Setting the cross-section of the plate-shaped portion to be curved can make the conveying process smoother.

[0010] In one embodiment, the two ends of the air distributor are fixedly connected to the air outlet and the protective shell, respectively. Fixedly connecting the two ends of the air distributor to the air outlet and the protective shell makes the air distributor more stable and reliable after assembly.

[0011] In one embodiment, a first sealing ring is further included, which is sandwiched between the air outlet and the protective shell. The first sealing ring prevents air from escaping through the gap between the air outlet and the protective shell, effectively improving air utilization efficiency and facilitating the formation of greater air pressure.

[0012] In one embodiment, the air distribution component includes a support shell and an air distribution plate. The support shell is connected to the air outlet, and the air distribution plate is connected to the support shell. The air distribution plate divides the air passage into two sections. The support shell allows the air distribution component to be mounted on the air outlet. The air distribution plate, as a plate-like portion, divides the air passage into two sections, causing the airflow to be split into two passages after entering through the air inlet. The structure of the air distribution plate not only makes the airflow distribution within the air passage more uniform, reducing wind power loss and operating noise caused by the airflow being concentrated on one side after pressurization, but also occupies less space within the air passage, avoiding affecting the airflow volume.

[0013] In one embodiment, the air outlet includes a guide portion and a limiting portion. The limiting portion is disposed on the guide portion and on the protective shell. A portion of the guide portion protrudes towards the receiving cavity to form a guide surface. The air distributor is connected to the portion of the guide portion that protrudes towards the receiving cavity. To further reduce the pressure loss of airflow in the air passage, a limiting portion is provided on the air outlet, which is fixedly connected to the protective shell. The guide portion is connected to the air distributor, and the airflow is guided by the protrusion towards the receiving cavity to form a guide surface. This guides the gas flowing from the air inlet of the air distributor towards the air outlet, thereby making the airflow in the air passage smoother and avoiding large turbulence and flow problems caused by internal gas flow.

[0014] In one embodiment, the air outlet further includes a connecting portion disposed on the air guide portion. A recess is formed on the air distributor, and the connecting portion is adapted to the recess of the air distributor, thus connecting the connecting portion to the air distributor. By providing a recess on the air distributor that adapts to the connecting portion, the air outlet can be embedded into the recess through the connecting portion, making the structure between the air outlet and the air distributor more stable and reliable, and reducing the space occupied in the air passage. Simultaneously, the transition structure between the air guide surface formed on the air guide portion and the air distributor is more compact.

[0015] In one embodiment, a heat insulation frame is further included for mounting the heating component. The heat insulation frame is sandwiched between the air outlet and the air distributor. By sandwiching the heat insulation frame between the air outlet and the air distributor, and by using the heat insulation frame to position the heating component within the air passage, a heating zone for the airflow is formed at the mounting location of the heating component. The air distributor then more evenly directs the airflow to the heating zones on both sides, resulting in better heating of the gas by the heating component.

[0016] In one embodiment, the air outlet further includes a limiting plate. A limiting groove is formed in the area where the air guide portion connects to the limiting portion. The limiting plate is disposed on the air guide portion and located at the limiting groove. An installation notch is provided on the heat insulation frame, and the installation notch is adapted to the limiting plate. To improve the connection stability between the heat insulation frame and the air outlet, a limiting groove is formed between the connection area of ​​the air guide portion and the limiting portion. A portion of the heat insulation frame is inserted into the limiting groove, and the limiting plate on the air outlet can be engaged with the installation notch of the support portion, making the connection structure between the heat insulation frame and the air outlet more reliable and compact.

[0017] In one embodiment, the heat insulation frame includes a support body, a support portion, and a fuse. The support portion is disposed on the support body, the support body abuts against the air distribution component, and the support portion abuts against the air outlet component. The support portion has a limiting notch for fitting with the heating component. The fuse is disposed on the support body or the support portion 42. The fuse on the heat insulation frame is used to monitor the heating temperature of the heating component and provide temperature protection when the temperature is too high. By providing a support body for abutting against the air distribution component, the airflow can flow more smoothly along the guide of the air distribution component through the heating component disposed on the heat insulation frame. The limiting notch on the support portion for fitting with the heating component makes the connection structure between the heating component, air distribution component, heat insulation frame, and air outlet component more compact, reducing the space occupied by the components in the air passage and the impact on the airflow.

[0018] The second embodiment of this application discloses a hair dryer.

[0019] A hair dryer includes: any one of the above-mentioned air guide components; a heating component disposed on the air guide component and located within the receiving cavity; a circuit board assembly disposed on the air guide component and located within the receiving cavity; a handle assembly disposed on the air guide component, the handle assembly having an air duct communicating with the receiving cavity; and a fan assembly disposed on the handle assembly and located within the air duct. By providing a fan assembly on the handle assembly, the fan assembly generates a high-pressure airflow within the air duct and directs it into the air guide component. The heating component on the air guide component heats the airflow within the air duct. An air distribution element within the air guide component guides the input pressurized air and delivers it through an air outlet, thereby making the gas flow inside the hair dryer more stable, enabling more uniform gas delivery, and improving the user experience.

[0020] In one embodiment, the protective shell includes an outer shell assembly and a partition plate. The outer shell assembly has the receiving cavity and an air inlet. The partition plate is disposed on the outer shell assembly and located within the receiving cavity. The partition plate axially divides the receiving cavity into a hot air cavity and a mounting cavity. The partition plate is curved. One side of the air distributor faces the partition plate, forming a first air distribution channel between the air distributor and the partition plate. The other side of the air distributor faces the side of the outer shell assembly with the air inlet, forming a second air distribution channel between the air distributor and the outer shell assembly. The heating assembly is located within the hot air cavity, which communicates with the air duct. The circuit board assembly is located within the mounting cavity. By dividing the receiving cavity with the partition plate to form a hot air cavity for mounting the heating assembly and a mounting cavity, and placing the circuit board assembly within the mounting cavity, the circuit board assembly is protected from the influence of the heating assembly, improving the safety and durability of the circuit board assembly. The partition plate divides the channel into upper and lower sections, allowing for better guidance during air delivery. Furthermore, the position of the partition plate can be adjusted to ensure a more uniform final airflow.

[0021] Optionally, the housing assembly includes a housing body, a cover plate, and an inner shell. The cover plate is disposed on the housing body, and the cover plate and the housing body enclose the receiving cavity. The inner shell is located within the receiving cavity and is sandwiched between the housing body and the cover plate. By placing the inner shell between the housing body and the cover plate, the inner shell can provide a certain degree of heat insulation, preventing the housing body of the air guide assembly from becoming too hot and affecting user operation.

[0022] Optionally, a second sealing ring is also included, which is sandwiched between the cover plate and the inner shell. The second sealing ring prevents air from escaping through the gap between the cover plate and the inner shell, effectively improving air utilization efficiency and facilitating the formation of greater air pressure.

[0043] 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.

[0044] 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.

[0045] The air guide assembly and hair dryer of some embodiments of the present invention are described below with reference to the accompanying drawings.

[0046] Example 1

[0047] like Figures 1 to 7 As shown, this embodiment discloses an air guiding assembly, including a protective shell 1, a receiving cavity 101, an air inlet 102 on the protective shell 1, the air inlet 102 communicating with the receiving cavity 101, and the air inlet 102 located on the side wall of the protective shell 1; an air outlet 2, disposed on the protective shell 1, forming an air outlet 103 between the air outlet 2 and the protective shell 1, or an air outlet 103 is disposed on the air outlet 2, communicating with the receiving cavity 101, and the air outlet 103 located at the end of the protective shell 1 or the air outlet 2; and an air divider 3, disposed on the air outlet 2 and / or the protective shell 1, the extending direction of the air divider 3 being the same as the extending direction of the air inlet 102 toward the air outlet 103, forming an air passage between the air inlet 102 and the air outlet 103, and the air divider 3 dividing at least a portion of the air passage into multiple channels.

[0048] The air guiding assembly disclosed in this application forms a receiving cavity 101 within the protective housing 1, and the air inlet 102 communicates with the receiving cavity 101. For example, when outside air is pressurized, it can enter through the air inlet 102. After entering the receiving cavity 101, since the air distributor 3 is positioned opposite the air outlet 102, the pressurized air will be transported towards the air distributor 3. After passing through the air distributor 3, the air will be diverted and guided by multiple channels formed by the air distributor 3. After being guided by the air distributor 3, the air will be guided from the air inlet 102 towards the air outlet 103. The setting of the air distributor 3 can prevent pressurized air input from the side of the protective housing 1 from blowing directly towards the top wall, thus avoiding wind power loss, and can effectively improve the efficiency of wind power utilization. After the pressurized air is guided by the air distributor 3, the air delivery can be more uniform.

[0049] like Figures 2 to 6 As shown, in addition to the features of the above embodiments, this embodiment further specifies that at least a portion of the air distribution component 3 is plate-shaped, and the plate-shaped portion of the air distribution component 3 divides a portion of the air passage into multiple channels. By setting a portion of the air distribution component 3 to be plate-shaped, the air passage can be better divided through the plate structure, and the plate structure occupies a smaller area, thus reducing obstruction to pressurized air. This avoids the problem of small channels after division affecting usability. Furthermore, the air passage can be divided into different numbers such as two, three, four, five, six, seven, eight, and nine channels as needed.

[0050] like Figures 2 to 6As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the air distribution component 3 divides a portion of the air passage into two air distribution channels, the air outlet 103 is annular, the portion of the air outlet 103 near the side wall where the air inlet 102 is located is sequentially connected to one of the air distribution channels and the air inlet 102, and the portion of the air outlet 103 away from the side wall where the air inlet 102 is located is sequentially connected to the other air distribution channel and the air inlet 102. The air distribution component 3 dividing a portion of the air passage into two air distribution channels can better guide the airflow, avoiding excessive turbulence generated within the protective shell 1 by the air input from the air inlet, and enabling more stable and rational air utilization.

[0051] like Figure 2 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the plate-shaped portion of the air distributor 3 is arranged opposite to the air inlet 102 to separate the fluid input from the air inlet 102 into at least two streams. By arranging the plate-shaped portion of the air distributor 3 opposite to the air inlet 103, pressurized air can be directly guided when it enters, reducing losses in the channel and effectively improving the air delivery efficiency.

[0052] like Figure 5 and Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the cross-section of the plate-shaped portion of the air distribution component 3 is curved; by setting the cross-section of the plate-shaped portion to a curved surface, the conveying process can be made smoother.

[0053] like Figures 2 to 5 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the two ends of the air distributor 3 are fixedly connected to the air outlet 2 and the protective shell 1, respectively. Fixing the two ends of the air distributor 3 to the air outlet 2 and the protective shell 1 respectively makes the air distributor 3 more stable and reliable after assembly.

[0054] like Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further includes a first sealing ring 5, which is sandwiched between the air outlet 2 and the protective shell 1. The first sealing ring 5 prevents air from escaping through the gap between the air outlet 2 and the protective shell 1, effectively improving air utilization efficiency and facilitating the formation of greater air pressure.

[0055] like Figure 3 , Figure 4 and Figure 6As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the air distribution component 3 includes a support shell 31 and an air distribution plate 32. The support shell 31 is connected to the air outlet component 2, and the air distribution plate 32 is connected to the support shell 31. The air distribution plate 32 divides the air passage into two. By providing the support shell 31, the air distribution component 3 can be installed on the air outlet component 2. The air distribution plate 32, as a plate-shaped part, divides the air passage into two, so that the airflow is divided into two air passages after entering through the air inlet 102. The structure of the air distribution plate 32 not only makes the airflow distribution in the air passage more uniform, reducing the wind power loss and operating noise caused by the airflow being concentrated on the same side after being pressurized, but also occupies less space in the air passage, avoiding affecting the airflow volume of the air passage.

[0056] like Figures 3 to 5 , Figure 7 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the air outlet 2 includes an air guide portion 21 and a limiting portion 22. The limiting portion 22 is disposed on the air guide portion 21 and the protective shell 1. A portion of the air guide portion 21 protrudes towards the receiving cavity 101 to form an air guide surface. The air distributor 3 is connected to the portion of the air guide portion 21 that protrudes towards the receiving cavity 101. In order to further reduce the pressure loss of airflow in the air passage, the limiting portion 22 is provided on the air outlet 2 and is fixedly connected to the protective shell 1. The air guide portion 21 is connected to the air distributor 3 and protrudes towards the receiving cavity 101 to form an air guide surface, guiding the gas flowing along the air inlet 102 of the air distributor 3 towards the air outlet 103. This makes the airflow in the air passage smoother and avoids large turbulence and turbulence caused by internal gas flow.

[0057] like Figure 2 and Figure 7 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the air outlet component 2 also includes a connecting portion 24, which is disposed on the air guide portion 21. A recess is formed on the air distributor 3, and the connecting portion 24 is adapted to the recess of the air distributor 3, and the connecting portion 24 is connected to the air distributor 3. By providing a recess on the air distributor 3 that is adapted to the connecting portion 24, the air outlet component 2 can be embedded in the recess through the connecting portion 24, making the structure between the air outlet component 2 and the air distributor 3 more stable and reliable, and occupying less space in the air passage. At the same time, the transition structure between the air guide surface formed on the air guide portion 21 and the air distributor 3 is more compact.

[0058] like Figures 2 to 5 , Figure 8As shown, in addition to the features of the above embodiments, this embodiment further includes a heat insulation frame 4, which is used to install the heating component 200 and is sandwiched between the air outlet component 2 and the air distributor 3. By sandwiching the heat insulation frame 4 between the air outlet component 2 and the air distributor 3, and by using the heat insulation frame 4 to place the heating component 200 in the air passage, a heating area for the airflow is formed at the installation position of the heating component 200. The air distributor 3 guides the airflow more evenly to the heating areas on both sides, resulting in a better heating effect of the heating component 200 on the gas.

[0059] like Figure 4 and Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the air outlet component 2 also includes a limiting plate 23, the area where the air guide portion 21 and the limiting portion 22 are connected forms a limiting groove 201, the limiting plate 23 is disposed on the air guide portion 21, the limiting plate 23 is located at the limiting groove 201, and the heat insulation frame 4 is provided with an installation notch 402, which is adapted to the limiting plate 23. In order to improve the connection stability between the heat insulation frame 4 and the air outlet component 2, a limiting groove 201 is formed between the connection area of ​​the air guide portion 21 and the limiting portion 22, a portion of the heat insulation frame 4 is inserted into the limiting groove 201, and the limiting plate 23 provided on the air outlet component 2 can be engaged in the installation notch 402 of the support portion 42, making the connection structure between the heat insulation frame 4 and the air outlet component 2 more reliable and compact.

[0060] like Figure 2 , Figure 4 and Figure 7 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the heat insulation frame 4 includes a support body 41, a support part 42 and a fuse 43. The support part 42 is disposed on the support body 41. The support body 41 abuts against the air distribution member 3. The support part 42 abuts against the air outlet member 2. The support part 42 is provided with a limiting notch 401. The limiting notch 401 is used to adapt to the heating component 200. The fuse 43 is disposed on the support body 41 or the support part 42. The heat insulation frame 4 is equipped with a fuse 43 for monitoring the heating temperature of the heating component 200 and providing temperature protection when the temperature is too high. The support body 41 is provided to abut against the air distribution component 3, so that the airflow can flow more smoothly along the air distribution component 3 and pass through the heating component 200 set on the heat insulation frame 4. The support part 42 is provided with a limiting notch 401 for matching with the heating component 200, so that the connection structure between the heating component 200, the air distribution component 3, the heat insulation frame 4 and the air outlet component 2 is more compact, reducing the space occupied by the components in the air passage and the impact on the air volume.

[0061] Example 2

[0062] like Figure 9As shown, this embodiment discloses a hair dryer, including any of the above-mentioned air guide components 100; a heating component 200, which is disposed on the air guide component 100 and located within the receiving cavity 101; a circuit board assembly 300, which is disposed on the air guide component 100 and located within the receiving cavity 101; a handle assembly 400, which is disposed on the air guide component 100 and has an air duct 4001 that communicates with the receiving cavity 101; and a fan assembly, which is disposed on the handle assembly 400 and located within the air duct 4001. By providing a fan assembly on the handle assembly 400, the operation of the fan assembly generates a high-pressure airflow in the air duct 4001 and flows into the air guide assembly 100. The heating assembly 200 is provided on the air guide assembly 100 to heat the airflow in the air passage. The air distribution component 3 provided in the air guide assembly 100 guides the input pressurized air and delivers it through the air outlet 103, thereby making the gas flow inside the hair dryer more stable, enabling the gas delivery of the hair dryer to be more uniform, and improving the user experience of the hair dryer.

[0063] like Figure 2 As shown, in addition to the features of the above embodiments, this embodiment further defines: the protective shell 1 includes a shell assembly 11 and a partition plate 12. The shell assembly 11 is provided with a receiving cavity 101 and an air inlet 102 is opened on the shell assembly 11. The partition plate 12 is disposed on the shell assembly 11 and located in the receiving cavity 101. The partition plate 12 divides the receiving cavity 101 along the axial direction to form a hot air cavity 1011 and a mounting cavity 1012. The partition plate 12 is curved. One side of the air distribution component 3 faces the partition plate 12, and a first air distribution channel is formed between the air distribution component 3 and the partition plate 12. The other side of the air distribution component 13 faces the side of the shell assembly 11 where the air inlet 102 is provided, and a second air distribution channel is formed between the air distribution component 13 and the shell assembly 11. The heating component 200 is located in the hot air cavity 1011, and the hot air cavity 1011 is connected to the air duct 4001. The circuit board assembly 300 is located in the mounting cavity 1012. The receiving cavity 101 is divided by a partition plate 12 to form a hot air cavity 1011 for mounting the heating component 200 and a mounting cavity 1012. The circuit board assembly 300 is disposed in the mounting cavity 1012, so that the circuit board assembly 300 is not affected by the heating component 200, thus improving the safety and durability of the circuit board assembly 300. The partition plate 12 divides the channel into upper and lower air distribution channels, which can better guide the air during the delivery process. At the same time, the position of the partition plate can be adjusted to make the final output airflow more uniform.

[0064] like Figure 2As shown, in addition to the features of the above embodiments, this embodiment further defines: the outer casing assembly 11 includes an outer casing body 111, a cover plate 112, and an inner casing 113.

The inner casing 113 is located within the receiving cavity 101 and is sandwiched between the outer casing body 111 and the cover plate 112. By disposing the inner casing 113 between the outer casing body 111 and the cover plate 112, the inner casing 113 can play a certain role in heat insulation, preventing the outer casing body 111 of the air guide assembly 100100 from getting too hot and affecting user use.

[0065] Optionally, a second sealing ring 6 is also included, which is sandwiched between the cover plate 112 and the inner shell 113. The second sealing ring 66 can prevent air from escaping through the gap between the cover plate 112 and the inner shell 113, effectively improving air utilization efficiency and facilitating the formation of greater air pressure.

[0066] 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.

[0067] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
