Description

Technical Field

[0001] This application relates to the field of hair dryer technology, and in particular to a hair drying module, a hair dryer body, and a hair dryer. Background Technology

[0002] Hair dryers are everyday household items primarily used for drying hair and styling. Since users typically dry their hair frequently, to prevent the hot air from the dryer from damaging hair and causing dryness, some products now incorporate plasma generators or ion generators inside to eliminate static electricity, smooth hair, and sterilize.

[0003] In related technologies, the ion generator is mounted on a circuit board mounting bracket, back cover assembly, or air duct housing. This results in two problems: firstly, the ion generator occupies a large space, which is not conducive to the miniaturization of the hair dryer body; secondly, since there is a heating component inside the body, the heat radiation and hot airflow of the heating component will affect the ion generator. If the temperature is too high, the ion generator will produce fewer negative ions and is prone to failure, resulting in a shortened service life.

[0004] The above content is only used to help understand the technical solution of the invention and does not represent an admission that the above content is prior art. Summary of the Invention

[0005] In view of the above problems, the present invention proposes a hair drying module for a hair dryer, which aims to solve the technical problem that the ion generator inside the hair dryer is easily affected by high temperature, resulting in decreased efficiency or failure.

[0006] To achieve the above objectives, the hair drying module of the hair dryer proposed in this invention includes a heating component and an ion generator:

[0024] In one embodiment, the length direction of the air duct shell is consistent with the length direction of the drying module of the hair dryer, and an air inlet is provided on the peripheral wall of the air duct shell;

[0025] The hair drying module of the hair dryer also includes a mounting bracket for mounting control components, the mounting bracket including a mounting part and an air guide part connected to the outer periphery of the mounting part;

[0026] The mounting part is fixedly connected to the end of the cylinder near the wiring terminal of the ion generator of the dry hair module, and the mounting part has a through hole corresponding to the wiring terminal;

A heating element is circumferentially mounted on the outer peripheral wall of the cylindrical body. The outer wall of the mounting base is spaced from the inner peripheral wall of the cylindrical body to form a first heat-insulating space. An ion generator is at least partially installed within the mounting base. Thus, when the heating element mounted on the outer peripheral wall of the cylindrical body is operating, the cylindrical body provides primary insulation against heat from the heating element, while the first heat-insulating space provides secondary insulation. This multi-layered heat insulation through the heating element effectively reduces or prevents heat transfer from the heating element to the ion generator, thereby increasing the number of ions released by the ion generator and extending its service life. Furthermore, installing the ion generator in the mounting base inside the cylinder cavity allows for full utilization of the space within the cylinder cavity, resulting in a more compact structure and smaller footprint for the entire dry hair module. On the other hand, installing the ion generator inside the cylinder, compared to installing it in other locations, minimizes the risk of hot airflow blowing onto the ion generator, further increasing the number of ions released and extending its service life.

[0049] This invention proposes a hair drying module for a hair dryer.

[0050] In the embodiments of the present invention, please refer to Figures 1 to 5 The hair drying module 100 of the hair dryer includes a heating assembly 110 and an ion generator 120. The heating assembly 110 includes a heating frame 111 and a heating element (not shown). The heating frame 111 includes a cylindrical body 112 and a mounting base 116 disposed in the inner cavity of the cylindrical body 112. The outer wall of the mounting base 116 is spaced from the inner peripheral wall of the cylindrical body 112 to form a first heat insulation space 117. The heating element (not shown) is circumferentially disposed around the outer peripheral wall of the cylindrical body 112. The ion generator 120 is at least partially installed in the mounting base 116.

[0051] In this embodiment, the ion generator 120 can specifically be a negative ion generator 120, a plasma generator 120, etc., and can be selected according to actual needs, without specific limitations. It is understood that the hair drying module 100 of the hair dryer also includes an ion emitting needle electrically connected to the ion generator 120. This ion emitting needle can be installed on the outer peripheral wall of the barrel 112, or it can be installed on a substrate on the outer periphery of the barrel 112. When the hair drying module 100 is installed inside the hair dryer, the ion emitting needle faces the air outlet of the hair dryer to release a sufficient amount of ions.

[0052] The cylindrical body 112 of the heating frame 111 is used to mount heating elements such as heating wires and heating plates (not shown). The heating frame 111 can be made of plastic materials such as nylon. The mounting base 116 and the cylindrical body 112 can be made of the same material or different materials. The mounting base 116 and the cylindrical body 112 can be integrally formed or separately formed. To improve structural strength, the mounting base 116 and the cylindrical body 112 can optionally be integrally formed. The cross-section of the cylindrical body 112 can be circular, square, elliptical, etc. The shape of the mounting base 116 can be various, such as a cylindrical structure, a bracket structure, a support ring, etc. The specific structure of the mounting base 116 is not limited here, as long as the mounting base 116 can provide a mounting position for the ion generator 120.

[0053] The ion generator 120 can be directly embedded in the mounting base 116, or it can be fixedly connected to the mounting base 116 by means of snap-fit ​​or other methods. The distance between the mounting base 116 and the inner peripheral wall of the cylinder 112 can be selected and designed according to actual needs, and is not specifically limited here. When the mounting base 116 is installed in the inner cavity of the cylinder 112, the mounting base 116 is at least partially accommodated within the cylinder 112, that is, the mounting base 116 and the cylinder 112 are at least partially overlapped in the radial direction of the cylinder 112. By making the outer wall of the mounting base 116 spaced from the inner peripheral wall of the cylinder 112 to form a first heat insulation space 117, when the ion generator 120 is installed in the mounting base 116, the ion generator 120 will not directly contact the cylinder 112, but will be separated by the first heat insulation space 117.

[0054] When the hair drying module 100 is used in the hair dryer, all or most of the airflow flows through the outer periphery of the cylinder 112 to exchange heat with the heating element (not shown) on the outer peripheral wall of the cylinder 112 before flowing out. The hair drying module 100 of the hair dryer of the present invention includes a heating frame 111 comprising a cylinder 112 and a mounting base 116 installed in the inner cavity of the cylinder 112. The heating element (not shown) is circumferentially mounted on the outer peripheral wall of the cylinder 112. The outer wall of the mounting base 116 is spaced from the inner peripheral wall of the cylinder 112 to form a first heat insulation space 117. The ion generator 120 is at least partially installed in the mounting base 116. Thus, when the heating element (not shown) installed on the outer peripheral wall of the cylinder 112 is working, the cylinder 112 can provide primary insulation against the heat from the heating element (not shown), and the first heat insulation space 117 can provide secondary insulation against the heat from the heating element (not shown). This effectively reduces or prevents the heat from the heating element (not shown) from being transferred to the ion generator 120, effectively increasing the number of ions released by the ion generator 120 and extending its service life. Furthermore, installing the ion generator 120 in the mounting base 116 inside the cylinder 112 allows for full utilization of the space inside the cylinder 112, making the entire hair drying module 100 more compact and space-saving. Moreover, installing the ion generator 120 inside the cylinder 112, compared to installing it in other locations, minimizes the risk of hot airflow blowing onto the ion generator 120, further increasing the number of ions released by the ion generator 120 and extending its service life.

[0055] In one embodiment, such as Figures 1 to 5 As shown, the mounting base 116 is a mounting cylinder with at least one open end, and the length direction of the mounting cylinder is consistent with the length direction of the cylinder body 112. The outer peripheral wall of the mounting cylinder is spaced apart from the inner peripheral wall of the cylinder body 112 to form the first heat insulation space 117, and the ion generator 120 is installed inside the mounting cylinder.

[0056] The ion generator 120 is installed inside the mounting cylinder through this opening. The length direction of the mounting cylinder is aligned with the length direction of the cylinder body 112, allowing the axis of the mounting cylinder to be collinear, parallel, or at an angle of at least 5 degrees to the axis of the cylinder body 112. The cross-section of the mounting cylinder can be circular, elliptical, rectangular, etc., as long as it is cylindrical overall. Aligning the length direction of the mounting cylinder with the length direction of the cylinder body 112 fully utilizes the space within the cylinder body 112 to accommodate the mounting cylinder, resulting in a more rational overall layout. By making the mounting base 116 an open-end mounting cylinder, compared to setting the mounting base 116 as a bracket formed by multiple support arms, the peripheral wall of the mounting cylinder can provide three levels of heat insulation for the ion generator 120. This further reduces the heat transfer from the heating elements (not shown) on the outer periphery of the cylinder body 112 to the ion generator 120, thereby further increasing the ion release rate of the ion generator 120 and extending its service life.

[0057] Furthermore, the minimum distance between the outer peripheral wall of the mounting cylinder and the inner peripheral wall of the cylinder body 112 is greater than or equal to 5 mm and less than or equal to 10 mm. Specifically, the minimum distance between the outer peripheral wall of the mounting cylinder and the inner peripheral wall of the cylinder body 112 can be 5 mm, 5.5 mm, 6 mm, 6.5 mm, 6.8 mm, 7 mm, 9 mm, 10 mm, etc.

[0058] Understandably, when the cross-section of at least one of the mounting cylinder and the cylinder body 112 is non-circular, the distance between their peripheral walls will be unequal, resulting in a maximum and a minimum distance. When the minimum distance between the outer peripheral wall of the mounting cylinder and the inner peripheral wall of the cylinder body 112 is less than 5mm, the distance between them is too small, resulting in a small first heat insulation space 117 and poor heat insulation effect. When the minimum distance between the outer peripheral wall of the mounting cylinder and the inner peripheral wall of the cylinder body 112 is greater than 10mm, the distance is too large, leading to wasted space and an excessively large overall footprint, which is detrimental to the miniaturization of the dry-generation module 100. By ensuring that the minimum distance between the outer peripheral wall of the mounting cylinder and the inner peripheral wall of the cylinder 112 is greater than or equal to 5mm and less than or equal to 10mm, the first heat insulation space 117 formed between the mounting cylinder and the cylinder 112 is sufficient to meet the heat insulation effect, while making the structure of the entire dry module 100 more compact and occupying less space, which is more conducive to achieving miniaturization and portability of the whole machine.

[0059] In one embodiment, please refer to Figure 2 and Figure 5One end of the mounting cylinder is fixedly connected to the cylinder body 112, and the other end is suspended in the inner cavity of the cylinder body 112. In this way, the contact area between the mounting cylinder and the cylinder body 112 can be minimized, thereby further reducing the heat transferred from the cylinder body 112 to the mounting cylinder, and thus effectively preventing heat from being transferred to the ion generator 120 inside the mounting cylinder.

[0060] Furthermore, one end of the cylinder 112 has an end wall 113, and the other end has an opening 114. The middle portion of the end wall 113 is concave and extends toward the opening 114 to form the mounting cylinder. The concave middle portion of the end of the cylinder 112 forms the mounting cylinder, making the mounting cylinder and the cylinder 112 an integral structure, thus ensuring the connection strength between the two. Moreover, the end wall 113 of the cylinder 112 can block airflow from entering the first heat insulation space 117. When the ion generator 120 is installed in the mounting cylinder, the airflow is blocked by the end wall 113 and the ion generator 120, and only flows through the outer periphery of the cylinder 112 to exchange heat with the heating element (not shown), thereby improving the heating efficiency of the airflow by the dry hair module 100.

[0061] In one embodiment, such as Figure 1 , Figures 4 to 6 , Figure 8 and Figure 9 The hair drying module 100 of the hair dryer also includes a first heat insulation sleeve 130, which is fitted and fixedly connected to the outer peripheral wall of the cylinder 112, and the heating element (not shown) is arranged around the outer periphery of the first heat insulation sleeve 130.

[0062] In this embodiment, the first heat insulation sleeve 130 can be made of heat insulation materials such as mica. The first heat insulation sleeve 130 and the cylinder 112 can be fixedly connected to the outer peripheral wall of the cylinder 112 by means of adhesive or other methods. To ensure overall appearance consistency and facilitate the installation of the heating element (not shown), optionally, a groove is provided on the outer peripheral wall of the cylinder 112, and the first heat insulation sleeve 130 is embedded in the groove, with the outer peripheral wall of the first heat insulation sleeve 130 smoothly transitioning to the outer peripheral wall of the cylinder 112. By fitting the first heat insulation sleeve 130 on the outer peripheral wall of the cylinder 112 to isolate the heating element (not shown) from the cylinder 112, heat transfer from the heating element (not shown) to the heating frame 111 can be effectively prevented, further reducing heat transfer to the ion heater, and greatly improving the negative ion release and service life of the ion generator 120.

[0063] Furthermore, the hair drying module 100 of the hair dryer also includes a second heat insulation sleeve 140 and a plurality of support plates 150. The plurality of support plates 150 are arranged circumferentially around the outer periphery of the first heat insulation sleeve 130 and are fixedly connected to the cylinder 112. The second heat insulation sleeve 140 is sleeved and connected to the outer periphery of the plurality of support plates 150. The heating element (not shown) is fixed to the plurality of support plates 150, and the heating element (not shown) is disposed between the first heat insulation sleeve 130 and the second heat insulation sleeve 140, or the heating element (not shown) is disposed between the support plate 150 and the second heat insulation sleeve 140.

[0064] In this embodiment, the second heat insulation sleeve 140 and the support plate 150 can be made of heat insulation materials such as mica. Multiple support plates 150 can be fixed to the cylinder 112 and the first heat insulation sleeve 130 by means of insertion, adhesive bonding, etc. The heating element (not shown) can specifically be a heating wire. Multiple support plates 150 provide support and connection for the heating wire. The support plate 150 can be a single plate or partially perforated to allow the heating wire to pass through. The second heat insulation sleeve 140 can be fixedly connected to the outer peripheral wall of the multiple support plates 150 by means of adhesive bonding, etc. By setting the second heat insulation sleeve 140 around the first heat insulation sleeve 130 to form an annular air duct for airflow, and setting the heating wire between the first heat insulation sleeve 130 and the second heat insulation sleeve 140, or between the support plate 150 and the second heat insulation sleeve 140, the flowing air can be heated, ensuring the heating efficiency of the entire hair drying module 100.

[0065] The hair drying module 100 of the hair dryer of the present invention provides multi-layer heat insulation for the ion generator 120 through the installation cylinder, the first heat insulation space 117, the cylinder body 112, the first heat insulation sleeve 130, and the second heat insulation sleeve 140. This effectively prevents the heat and hot air flow of the heating element (not shown) from being transferred to the ion generator 120, greatly avoiding the ion generator 120 being in a high-temperature environment, and maximizing the ion release quantity and service life of the ion generator 120.

[0066] In one embodiment, please refer to Figure 5 , Figure 8 and Figure 9 The mounting base 116 is connected to one end of the cylinder 112, and the first heat insulation sleeve 130 extends beyond the other end of the cylinder 112 to enclose and form a mounting cavity 131 for accommodating the central recess of the air supply component.

[0067] In this embodiment, when the hair drying module 100 is installed inside the hair dryer casing 200, an air outlet is provided downstream of the airflow channel of the hair drying module 100 to guide the airflow that has passed between the first heat insulation sleeve 130 and the second heat insulation sleeve 140 and has undergone heat exchange to flow out through a preset trajectory. By extending the first heat insulation sleeve 130 beyond the other end of the casing 112, a space can be formed inside the first heat insulation sleeve 130 to accommodate the central concave portion of the air outlet. On the one hand, the first heat insulation sleeve 130 can limit the position of the air outlet, making the installation of the air outlet more stable and reliable, and at the same time making the overall structure more compact; on the other hand, the first heat insulation sleeve 130 can insulate the central concave portion of the air outlet, thereby improving the service life of the air outlet.

[0068] In one embodiment, the drying module 10 of the hair dryer includes at least one ion-emitting needle (not shown) electrically connected to the ion generator 120. The ion-emitting needle (not shown) is fixed between the barrel 112 and the first heat insulation sleeve 130. The ion-emitting needle (not shown) is electrically connected to the ion generator 120 to release ions at its emitting tip. The number of ion-emitting needles (not shown) can be selected according to actual needs. Typically, to increase the ion release concentration, multiple ion-emitting needles (not shown) are provided, and the multiple ion-emitting needles (not shown) are spaced apart circumferentially around the barrel 112. Specifically, the fixed end of the ion-emitting needle (not shown) is fixed between the barrel 112 and the first heat insulation sleeve 130, and the emitting tip of the ion-emitting needle (not shown) is arranged radially away from the barrel 112. By fixing the ion emitting needle (not shown) between the cylinder 112 and the first heat insulation sleeve 130, the ion emitting needle (not shown) can be insulated from the heating element (not shown), ensuring the normal operation of the ion emitting needle (not shown). On the other hand, the cylinder 112 and the first heat insulation sleeve 130 can insulate the ion emitting needle (not shown), thereby increasing the number of ions released and extending the service life of the ion emitting needle (not shown).

[0069] In one embodiment, such as Figure 1 , Figure 3 , Figure 5 , Figure 6 , Figure 8 and Figure 9 As shown, the ion generator 120 is installed inside the mounting cylinder along its length; the depth of the mounting cylinder is greater than half the length of the ion generator 120.

[0070] In this embodiment, by mounting the ion generator 120 along its length inside the mounting cylinder, wiring is facilitated, the space along the length of the mounting cylinder is fully utilized, and the distance between the outer peripheral wall of the mounting cylinder and the inner peripheral wall of the cylinder body 112 can be set larger, ensuring sufficient thermal insulation distance between them. If the depth of the mounting cylinder is less than half the length of the ion generator 120, resulting in only a small portion of the ion generator 120 being installed inside the mounting cylinder and a portion exposed outside, it would be detrimental to the fixation of the ion generator 120 and would not provide efficient thermal insulation for the ion generator 120. However, by making the depth of the mounting cylinder greater than half the length of the ion generator 120, most of the ion generator 120 is installed inside the mounting cylinder, thus ensuring stable installation of the ion generator 120 while providing efficient thermal insulation for the ion generator 120.

[0071] In one embodiment, please refer to Figure 5 , Figure 8 and Figure 9 The cross-sectional area of ​​the mounting base 116 is larger than the cross-sectional area of ​​the ion generator 120, so that the outer peripheral wall of the ion generator 120 and the inner peripheral wall of the mounting base 116 are spaced apart to form a second heat insulation space 118.

[0072] Specifically, the bottom wall of the ion generator 120 can be bonded to the inner cavity bottom wall of the mounting base 116 using adhesive, clips, or other methods. Alternatively, the ion generator 120 can be fixed to the mounting base 116 by clamping at both ends. By creating a second heat-insulating space 118 between the outer peripheral wall of the ion generator 120 and the inner cavity peripheral wall of the mounting base 116, that is, the outer peripheral wall of the ion generator 120 does not directly contact the inner cavity peripheral wall of the mounting base 116, the heat transfer from the mounting base 116 to the ion generator 120 can be further reduced. This provides layered heat insulation for the ion generator 120, minimizing the impact of high temperatures on the ion generator 120, allowing it to release a sufficient number of ions, and greatly extending its service life. The distance between the outer peripheral wall of the ion generator 120 and the inner cavity peripheral wall of the mounting base 116 can be selected and designed according to actual needs, and is not specifically limited here.

[0073] In one embodiment, such as Figures 4 to 6 , Figure 8 and Figure 9The terminal 121 of the ion generator 120 extends out of the barrel 112; the drying module 100 of the hair dryer also includes a control component 160, which includes a control board 161 and an electrical component mounted on the side of the control board 161 facing the terminal 121. The electrical component and the terminal 121 are electrically connected to the control board 161; the electrical component abuts against the terminal 121 at the upper limit of the axial direction of the barrel 112.

[0074] In this embodiment, the control component 160 is used to control the operation of the heating element (not shown), ion generator 120, etc. The control board 161 is electrically connected to the heating element (not shown) and the terminal 121 of the ion generator 120. The terminal 121 of the ion generator 120 extends beyond the cylinder 112, making it easier to connect to the control board 161. By having electrical components on the control component 160 abut against the terminal 121 of the ion generator 120, the ion generator 120 is confined within the mounting base 116. This fully utilizes the electrical components on the control component 160 to limit the ion generator 120, preventing it from detaching from the mounting base 116. This eliminates the need for additional limiting structures, reduces the number of components in the hair drying module 100, and makes the overall structure of the hair drying module 100 more compact and space-saving.

[0075] In one embodiment, please refer to Figures 3 to 6 The hair drying module 100 of the hair dryer also includes a mounting bracket 170, which is fixedly connected to the end of the cylinder 112 adjacent to the terminal 121; the control component 160 is fixedly mounted on the mounting bracket 170, and the mounting bracket 170 is provided with a through hole 172 for the terminal 121 to pass through.

[0076] In this embodiment, the mounting bracket 170 and the cylinder 112 can be fixedly connected by screws, clips, or other means. The structure and form of the mounting bracket 170 can be varied and can be selected and designed according to actual needs; no specific limitation is made here. The control component 160 and the mounting bracket 170 can also be fixed in various ways, such as screw fixing, welding, or bonding. By opening a through hole 172 on the mounting bracket 170 for the wiring terminal 121 to pass through, the wiring terminal 121 of the ion generator 120 is electrically connected to the control board 161 through the through hole 172 of the mounting bracket 170, and the electrical components on the control board 161 can abut against the wiring terminal 121 of the ion generator 120. It is understood that the mounting bracket 170 does not fix or support the ion generator 120; it only serves to allow the wiring terminal 121 of the ion generator 120 to pass through. The ion generator 120 is fixedly installed within the mounting base 116. By fixing the mounting bracket 170 for mounting the control component 160 to the end of the cylinder 112 adjacent to the terminal 121, the wiring distance between the control component 160 and the ion generator 120 can be shortened, making the structure of the control component 160 and the heating component more compact and occupying less space, which is more conducive to the miniaturization of the hair dryer.

[0077] Furthermore, the end wall 113 of the cylindrical body 112 facing the mounting bracket 170 is provided with a plurality of fixing posts 115 surrounding the mounting base 116. The mounting bracket 170 is provided with a plurality of mounting holes 177 corresponding to the fixing posts 115. The hair drying module 100 of the hair dryer also includes a plurality of connectors, which pass through and connect the mounting holes 177 and the fixing posts 115. The number of fixing posts 115 can be two, three, four, six, etc., and can be selected and designed according to actual needs, without being specifically limited here. The fixing posts 115 are arranged around the mounting base 116 to ensure a stable connection between the mounting bracket 170 and the cylindrical body 112 while avoiding the connectors from affecting the installation of the ion generator 120. The fixing posts 115 can be provided with screw holes, and the connector is a stud. The stud passes through the mounting holes 177 on the mounting bracket 170 and the screw holes on the fixing posts 115, and is threadedly connected to a nut to achieve a fixed connection between the mounting bracket 170 and the cylindrical body 112. This allows the cylinder 112 and the mounting bracket 170 to be connected by a connector, ensuring a stable connection while facilitating the assembly and disassembly of both.

[0078] Furthermore, such as Figure 5 and Figure 9 As shown, multiple fixing posts 115 are arranged axially on the cylinder 112 corresponding to the first heat insulation space 117. In this way, the operator can operate and install the connecting parts from the first heat insulation space 117, which makes it more convenient to assemble the bracket 170 and the heating frame 111.

[0079] In the above embodiment where the wiring terminal 121 of the ion generator 120 extends outside the cylinder 112, please further refer to... Figures 4 to 6 , Figure 8 and Figure 9 The ion generator 120 extends beyond the cylinder 112 by less than one-third of its total length. The electrical component includes a capacitor 162, which abuts against the terminal 121 axially within the cylinder 112. This arrangement ensures the ion generator 120 is securely mounted on the mounting base 116 while allowing its terminal 121 to pass through the through-hole 172 of the mounting bracket 170 and abut against the capacitor 162 on the control board 161. It is understood that the capacitor 162 on the control board 161 is relatively larger than other electrical components; the contact between the capacitor 162 and the terminal 121 of the ion generator 120 makes the positioning of the ion generator 120 more stable and reliable.

[0080] The present invention also proposes a body 10 for a hair dryer, please refer to... Figures 7 to 9 The body 10 of the hair dryer includes a blower shell 200 and a hair drying module 100. The specific structure of the hair drying module 100 is as described in the above embodiments, and the hair drying module 100 is installed inside the blower shell 200. Since the body 10 of this hair dryer adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The blower shell 200 can be a single-layer shell or a double-layer shell, which can be selected and designed according to actual needs, and is not specifically limited here. In order to make the appearance more concise and beautiful, the blower shell 200 is preferably cylindrical. The hair drying module 100 is installed in the inner cavity of the blower shell 200 to heat the airflow inside the blower shell 200 and release sufficient negative ions and / or positive ions, etc. The heated airflow and negative ions, positive ions, etc. are mixed and blown out by the blower shell 200.

[0081] In one embodiment, such as Figures 5 to 9 As shown, the length direction of the duct shell 200 is consistent with the length direction of the cylinder 112 of the hair drying module 100 of the hair dryer, and the peripheral wall of the duct shell 200 is provided with an air inlet 210.

[0082] The hair drying module 100 of the hair dryer also includes a mounting bracket 170 for mounting the control component 160. The mounting bracket 170 includes a mounting part 171 and an air guide part 174 connected to the outer periphery of the mounting part 171.

[0083] The mounting part 171 is fixedly connected to the end of the terminal 121 of the ion generator 120 of the dry hair module 100 adjacent to the cylinder 112. The mounting part 171 has a through hole 172 corresponding to the terminal 121.

[0084] The air guide section 174 is provided corresponding to the air inlet 210 to guide the airflow of the air inlet 210 to the heating component 110 of the hair drying module 100; the air guide section 174 is provided with an air flow hole 175 for the airflow of the air inlet 210 to flow to the through hole 172.

[0085] In this embodiment, the length direction of the air duct shell 200 is consistent with the length direction of the cylinder 112 of the hair drying module 100, which allows the axis of the air duct shell 200 to be collinear, parallel, or have an angle of not less than 5 degrees with the axis of the cylinder 112. Typically, an air outlet is formed on the end wall 113 of the air duct shell 200. The heating element 111 of the hair drying module 100 is integrally assembled into the air duct shell 200 along the axial direction, which makes the overall structure more compact. The airflow inside the air duct shell 200 flows through the outside of the cylinder 112, passes around the heating element (not shown), and is blown out from the air outlet of the air duct shell 200.

[0086] An air inlet 210 is provided on the peripheral wall of the air duct housing 200, allowing the handle 20 of the hair dryer to be fixed at the air inlet 210. The fan assembly 23 introduces external airflow through the air inlet 22 on the handle 20, and then blows it through the air inlet 210 to the mounting bracket 170. The mounting part 171 can be an end plate, a cylindrical structure, etc., as long as it can be fixedly connected to the cylinder 112 and provide installation and support for the control assembly 160. The wiring terminal 121 of the ion generator 120 passes through the through hole 172 on the mounting part 171, and its axial movement is restricted by the capacitor 162 mounted on the mounting bracket 170. The air guide part 174 can have many shapes, such as a bent plate or an arc plate. By including the air guide part 174 in the mounting bracket 170, the air guide part 174 can be used to guide the airflow from the air inlet 210 to the heating assembly 110, thereby increasing the airflow heating efficiency of the hair dryer. The number and diameter of the airflow holes 175 can be selected and designed according to actual needs. For example, the airflow holes 175 can be set to one or more. By opening the airflow holes 175 on the air guide section 174, the unheated airflow entering the air duct shell 200 from the air inlet 210 can be blown towards the control component 160 and the negative ion generator 120 through the airflow holes 175, which can dissipate heat and cool down the control component 160 and the ion generator 120, thereby extending the service life of the control component 160 and the ion generator 120.

[0087] Furthermore, please refer to the following: Figure 3 and Figure 6The mounting portion 171 has a heat dissipation channel 173 communicating with the through hole 172, and the heat dissipation channel 173 is provided corresponding to the heating frame 111. The heat dissipation channel 173 can be a single channel or multiple channels spaced circumferentially around the ion generator 120. By providing the heat dissipation channel 173 communicating with the through hole 172 on the mounting portion 171, the cold airflow entering through the airflow hole 175 can further flow to the ion generator 120, effectively cooling and dissipating heat from the ion generator 120.

[0088] Furthermore, such as Figures 4 to 9 As shown, the control component 160 is mounted on the side of the mounting bracket 170 opposite to the heating component 110. The mounting bracket 170 also includes a heat insulation portion 176, which surrounds and connects to the outer periphery of the mounting portion 171 away from the air inlet 210. The heat insulation portion 176 is used to separate the control component 160 and the heating component 110 axially within the air duct housing 200. The mounting bracket 170 separates the control component 160 and the heating component 110 through the heat insulation portion 176. While not affecting the airflow from the air inlet 210 to the heating component 110, it effectively prevents the hot airflow heated by the heating component 110 and the heat radiation from the heating component 110 from affecting the electrical components of the control component 160, thereby extending the service life of the control component 160. Specifically, the heat insulation portion 176 may be in the shape of an arc surrounding the outer periphery of the mounting portion 171. Thus, the heat insulation part 176 can also guide the airflow of the air inlet 210 to flow around its circumference, thereby enabling the airflow to flow evenly to the heating element (not shown) outside the cylinder 112 of the heating frame 111.

[0089] This invention also proposes a hair dryer, please refer to... Figures 7 to 9 The hair dryer includes a handle 20 and a body 10. The specific structure of the body 10 is as described in the above embodiments. The handle 20 is fixedly connected to the air duct shell 200 of the body 10. Since the body 10 of this hair dryer adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. The handle 20 and the air duct shell 200 can be an integral structure or a separate structure. When the handle 20 and the air duct shell 200 are separate structures, the connection between the handle 20 and the air duct shell 200 can be detachable or non-detachable. The structure and form of the handle 20 can be many, and specific designs can be referred to, which are not specifically limited here.

[0090] Specifically, the handle 20 includes a handle housing 21 and a fan assembly 23 installed within the handle housing 21. The handle housing 21 is fixedly connected to the peripheral wall of the air duct housing 200. An air inlet 22 is provided on the handle housing 21. The fan assembly 23 drives airflow through the air inlet 22 into the handle housing 21, flows through the hair drying module 100, and is then blown out through the air outlet of the hair dryer body 10. Installing the fan assembly 23 within the handle housing 21 reduces the weight of the hair dryer body 10, resulting in a more even weight distribution and improved user experience. The specific structure of the fan assembly 23 can refer to existing designs and is not specifically limited here.

[0091] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
