[0038] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0039] Please see Figures 1 to 3 As shown, Figure 1 This is a schematic diagram of the structure of the heater 10 provided according to some embodiments of this application. Figure 2 and Figure 3 The images show a side view and a top view of the heater 10, respectively. The heater 10 provided in this embodiment can be applied to, for example... Figure 8 In the hair dryer 100 shown, the airflow of the hair dryer 100 is heated so that the hair dryer 100 blows out hot air. The hair dryer 100 includes a functional component that enables the hair dryer to perform the same function. The heating element 10 includes a frame 1 having an internal receiving area 11 and a heating element 2 disposed within the internal receiving area 11. The frame 1 defines the edge contour of the heating element 10. A clearance recess 13 is provided on the outer surface of the side of the frame 1 facing away from the internal receiving area 11. The clearance recess 13 is used to accommodate at least a portion of the functional component; that is, the clearance recess 13 provides clearance space for the functional component to be disposed within the hair dryer 100, such that at least a portion of the functional component is located within the clearance recess 13.

[0040] The recessed area 13 provides clearance space for the functional components inside the hair dryer 100, thereby reducing the space occupied by the heater 10 and the functional components inside the blower 30 of the hair dryer 100. This helps to reduce the size of the hair dryer 100 and meets the needs of the portable development of the hair dryer 100.

[0041] The heating element 2 of the heater 10 provided in this embodiment is housed within the internal receiving area 11 of the frame 1, and is supported by the frame 1 on the airflow path of the hair dryer 100. The frame 1 can be a columnar structure extending along the airflow path of the hair dryer 100, with the recessed area 13 disposed on the outer surface of the circumferential sidewall of the columnar structure. The size of the recessed area 13 can be matched with the size of the functional component, thereby providing better clearance space for the functional component. Here, the matching can include matching the recess depth of the recessed area 13, the extension width in the cross-sectional direction of the columnar structure sidewall, and the extension length in the airflow path direction with the corresponding dimensions of the functional component.

[0042] In some embodiments, the aforementioned functional components may be as follows: Figures 8 to 10The essential oil atomizing component 40 shown is described. At least a portion of the essential oil storage container of the essential oil atomizing component 40 may be located in the avoidance recess 13 to reduce the space occupied by the essential oil atomizing component 40 within the blower 30, thereby improving the space utilization within the blower 30.

[0043] Please continue reading. Figures 1 to 3 As shown, in some embodiments, the frame 1 includes a plurality of annular frames 12 stacked along the airflow path of the blower 100. The plurality of annular frames 12 form an internal receiving area 11 and a clearance recess area 13. The clearance recess area 13 is formed on the circumferential outer surface of the annular frame 12, and the clearance recess areas 13 of each annular frame 12 are aligned to form a recessed space extending along the airflow path direction for accommodating at least a portion of a functional component.

[0044] In this application, the term "ring" is not limited to a circular ring in an absolute geometric sense, but includes some ring structures that are generally circular but have irregular shapes in some parts.

[0045] The heating element 2 is filled in the inner receiving area 11 of the annular frame 12. The contact pieces 21 at both ends of the heating element 2 are located in the avoidance recess area 13 to reduce the space occupied by the interconnection of the contact pieces 21.

[0046] In this embodiment, the frame 1 is formed by stacking multiple ring frames 12, which makes it easy to add or remove ring frames 12 as needed, so that the application of the heater 10 has high flexibility and can maximize the heating performance of the heater 10 within a limited space.

[0047] In some embodiments, the heater 10 includes a first heating component 14 and a second heating component 15. The first heating component 14 and the second heating component 15 each include one or more annular frames 12 filled with heating elements 2, and the first heating component 14 and the second heating component 15 are separated by annular frames 12 not filled with heating elements 2. The plurality of heating elements 2 of the first heating component 14 are connected in series to form a first series branch, and the plurality of heating elements 2 of the second heating component 15 are connected in series to form a second series branch.

[0048] In this embodiment, the heating elements 2 included in the first heating component 14 and the second heating component 15 are connected in series, which helps to increase the heating resistance of the heater 10, thereby increasing the heating effect of the heater 10. In some embodiments, the first heating component 14 and the second heating component 5 are electrically connected in parallel, that is, the first series branch and the second series branch are connected in parallel. The first heating component 14 and the second heating component 15 can work independently or together, so that the heater 10 can obtain basically the same power under different power supply voltages, thereby enabling the hair dryer 100 to work normally under different power supply voltages.

[0049] In some embodiments, in the first heating assembly 14 and the second heating assembly 15, the contact pieces 21 at the beginning and end of two adjacent heating elements 2 are electrically connected by an electrical connecting piece 22, so as to connect each heating element 2 in the first heating assembly 14 and the second heating assembly 15 in series. Two adjacent heating elements 2 in the first heating assembly 14 and the second heating assembly 15 are also electrically connected by a connecting piece 22, thereby realizing a parallel connection between the first heating assembly 14 and the second heating assembly 15. In this embodiment, the electrical connecting piece 22 is located within the clearance recess 13, and each contact piece 21 is electrically connected within the clearance recess 13 via the electrical connecting piece 22, which helps to reduce the space occupied by the heater 10 within the air duct 30.

[0050] In some embodiments, the first heating element 14 and the second heating element 15 each include four annular frames 12 in which heating elements 2 are embedded, so that the heater 10 has a suitable volume and excellent heating performance. In other embodiments, the first heating element 14 and the second heating element 15 may each include other numbers of annular frames 12.

[0051] In some embodiments, the thickness of the annular frame 12 used to separate the first heating component 14 and the second heating component 15 in the airflow path direction is greater than the thickness of each annular frame 12 in the first heating component 14 and / or the second heating component 15, so as to ensure the separation effect.

[0052] Please see Figure 4 The diagram shows a schematic representation of an annular frame 12 containing a heating element 2, provided according to some embodiments of this application. In some embodiments, the annular frame 12 includes an outer frame 121 and an inner frame 122, with an internal receiving area 11 located between the outer frame 121 and the inner frame 122. The heating element 2 is filled in the internal receiving area 11 located between the outer frame 121 and the inner frame 122 in a reciprocating manner. A recessed area 13 is provided on the circumferential outer surface of the outer frame 121 and is recessed towards the inner frame 122, with a certain distance between it and the inner frame 122, so that a certain filling area is left at the position corresponding to the recessed area 13 to fill the heating element 2.

[0053] In this embodiment, the annular frame 12 is a hollow structure composed of an outer frame 121 and an inner frame 122, which allows the heater 10 to be installed on the mounting post 201 of the mounting bracket 20 in a series, which helps to improve the stability of the heater 10 and reduce the installation complexity of the heater 10.

[0054] Figure 5 This is a schematic diagram of the mounting bracket 20 for the heater 10. Figure 6This is a schematic diagram of the mounting bracket 20 on which the heater 10 is installed. See also... Figure 5 and Figure 6 As shown, in some embodiments, the mounting bracket 20 further includes a protective cover 202, which covers the circumferential outer surface of the heater 10 to cover the recessed area 13. The protective cover 202 has a recessed portion 2021 corresponding to the recessed area 13 at a position opposite to the recessed area 13. The contact pieces 21 of each heating element 2 pass through the recessed portion 2021 of the protective cover 202 to connect with electrical wiring within the recessed portion 2021. The recessed portion 2021 and the recessed area 13 have the same recessing direction and the same size, allowing at least a portion of the functional components to be accommodated within the recessed portion 2021, thereby reducing the volume occupied in the air duct 30.

[0055] Please continue reading. Figure 4 As shown, in some embodiments, the internal receiving area 11 includes a first region 111 opposite to the avoidance recessed area 13, and the direction of the heating element 2 folding back and forth in the first region 111 is consistent with the extending direction of the adjacent sidewall 132 of the avoidance recessed area. This allows the filling density of the heating element 2 in the first region 111 to be as high as possible, that is, to make the first region 111 filled with the heating element 2 as saturated as possible, thereby allowing the heater 10 to have a larger heating area for more uniform heating of the airflow. Here, consistency means that the direction of the heating element 2 folding back and forth in the first region 111 is substantially parallel to or has a small angle with the extending direction of the adjacent sidewall 132 of the avoidance recessed area.

[0056] In some embodiments, the first portion of the heating element 2 located in the first region 111 includes a plurality of first extensions 23 and a plurality of first bends 24, with the first bends 24 connecting two adjacent first extensions 23. The first bends 24 near the outer frame 121 are connected to the outer frame 121, and the first bends 24 near the inner frame 122 are connected to the inner frame 122. The first portion of the heating element 2 is fixedly supported by the outer frame 121 and the inner frame 122. The avoidance recess 13 of each annular frame 12 includes a bottom 131 of the avoidance recess and two sidewalls 132 of the avoidance recess connected to the bottom 131 of the avoidance recess.

[0057] Due to the design of the recessed area 13, the first region 111 is an irregularly shaped area, making it impossible for the heating element 2 to have regular wiring in this region. In this embodiment, the extension direction of the first extension 23 is set to be consistent with the extension direction of an adjacent recessed area sidewall 132, thereby making the first part of the heating element 2 contain more of the first extension 23, so that the heating element 2 filling the first region 111 is as saturated as possible, thus allowing the heater 10 to have a larger heating area for more uniform heating of the airflow.

[0058] In some embodiments, the portion of the inner frame 122 of each annular frame 12 located in the first region 111 is a straight portion, thereby creating a certain gap between the recessed area 13 and the inner frame 122 to fill a higher density of heating elements 2, thereby increasing the heating performance of the heater 10.

[0059] In some embodiments, as the depth of the recessed area 13 increases, the distance between the two recessed area sidewalls 132 decreases, that is, in the direction from the inner frame 122 to the outer frame 121, the size of the recessed area 13 increases sequentially, thereby facilitating the provision of clearance space for setting functional components in the hair dryer 100.

[0060] In some embodiments, the annular frame 12 further includes a connecting strip 124 disposed between the outer frame 121 and the inner frame 122. One end of the connecting strip 124 is connected to the bottom 131 of the recessed area, and the other end is connected to the straight portion of the inner frame 122, with the connecting strip 124 perpendicular to the straight portion of the inner frame 122. The first extensions 23 on both sides of the connecting strip 124 are inclined away from the connecting strip 124 to align with the extension direction (or the inclination direction relative to the connecting strip 124) of the adjacent recessed area sidewall 132. The first extensions 23 can be straight lines, wavy lines, or serrated lines. The further away the first extensions 23 are from the connecting strip 124, the longer their length in the extension direction and the more inclined they are relative to the connecting strip 124, thereby allowing the heating element 2 filled in the first region 111 to be more saturated.

[0061] The first region 111 is divided into a first sub-region and a second sub-region via the connecting strip 124. The first sub-region is the starting area of ​​the reciprocating path of the heating element 2 within the internal housing area 11, and the second sub-region is the ending area of ​​the reciprocating path of the heating element 2 within the internal housing area 11. The first sub-region is the area on one side of the first region 111 near the contact piece 21 at the head end of the heating element 2, and the second sub-region is the area on one side of the second sub-region near the contact piece 21 at the tail end of the heating element 2. The reciprocating path of the heating element 2 in the first and second sub-regions can be serpentine or sawtooth-shaped.

[0062] Please continue reading. Figure 4 As shown, in some embodiments, the first bend 24 can be connected to the outer frame 121 and / or the inner frame 122 via a thin bridge 241. During operation of the heater 10, the thin bridge 241 may experience a small current flow. However, it should be understood that this current flow will be minimal and its effect on the entire heating element 2 is negligible.

[0063] Please see Figures 1 to 3 , Figure 4 and Figure 7 As shown, where Figure 6This is a schematic diagram of an annular frame 12 with a temperature control component installed and a heating element 2 inside. In some embodiments, the internal receiving area 11 further includes a second region 112, which is located near the inner frame 122 and is filled with the heating element 2 at a position opposite to the mounting area 27.

[0064] In this embodiment, the heating element 2 is also filled in the area of ​​the second region 112 other than the installation area 27, thereby increasing the heating area of ​​the heater 10 and heating the airflow more evenly.

[0065] In some embodiments, the temperature control component may include a thermostat 3 and / or a fuse 4. The thermostat 3 and / or fuse 4 are installed within the mounting area 27. The thermostat 3 and / or fuse 4 sequentially pass through the mounting areas 27 in each annular frame 12. The thermostat 3 is used to acquire and control the temperature of the heater 10, and the fuse 4 is used to disconnect the heater 10 from the power supply to provide over-temperature protection for the heater 10. Placing the temperature control component within the internal housing area 11 of the heater 10 helps to reduce the size of the heater 10.

[0066] Because a temperature control component needs to be installed in the second region 112, the remaining area of ​​the second region 112, excluding the mounting area 27, is an irregularly shaped area. The second portion of the heating element 2 fills the second region 112. The second portion of the heating element 2 includes a plurality of second extensions 25 and at least one second bend 26, the second bend 26 being used to connect two adjacent second extensions 25. The second extensions 25 extend from the side away from the inner frame 122 toward the mounting area 27, and terminate before reaching the mounting area 27 to reserve space for the mounting area 27.

[0067] In some embodiments, the first heating element 14 is located upstream of the second heating element 15 in the airflow path. The temperature control element passes through the first heating element 14 and the second heating element 15 sequentially from the side of the first heating element 14 away from the second heating element 15, and extends to the air outlet 70 of the hair dryer 100. This eliminates the need to set up additional space outside the space occupied by the heating element 10 to install the temperature control element, which helps to reduce the size of the hair dryer 100 and meet the needs of its portability development.

[0068] Please continue reading. Figure 4 or Figure 7 As shown, the second extension 25 can extend radially from the inner frame 122 toward the outer frame 121 along the annular frame 12, and does not contact the outer frame 121. In some embodiments, the second extension 25 is a wavy line or a serrated line, which can increase the heating area of ​​the heater 10 to improve the heating effect on the airflow.

[0069] In some embodiments, the thermostat 3 and the fuse 4 are spaced apart in the second region 112. The wiring of the heating element 2 in the second region 112 also includes a plurality of third extensions 29 disposed between the thermostat 3 and the fuse 4 and a third bend 210 connecting two adjacent third extensions 29. The third bend 210 near the outer frame 121 is connected to the outer frame 121, and the third bend 210 near the inner frame 122 is connected to the inner frame 122. The third extensions 29 and the third bend 210 in the second region 112 are supported and fixed by the outer frame 121 and the inner frame 122.

[0070] In some embodiments, a heating element support 28 is also provided in the second region 112. The heating element support 28 is fixed to the inner frame 122 and extends toward the outer frame 121 to support the heating element 2, thereby improving the structural stability of the heater 10 and improving the reliability of the heater 10.

[0071] Please continue reading. Figure 4 As shown, in some embodiments, the internal receiving area 11 further includes a third region 113. The third region 113 is a portion of an annulus defined by the outer frame 121 and the inner frame 122, that is, the third region 113 is a portion of a regular annular region. The heating element 2 is located in a third portion of the third region 113 and folds back and forth along the radial direction of the annular frame 12 to fill the third region 113 as much as possible.

[0072] In some embodiments, the third portion of the heating element 2 includes a plurality of the aforementioned third extensions 29 and a plurality of the aforementioned third bends 210. The third extensions 29 extend radially in the annular frame 12 and can be straight, wavy, or serrated. The bending trace of the third portion of the heating element 2 within the third region 113 can be serpentine or serrated.

[0073] In this embodiment, the third region 113 is free from other structural interference and is part of a regular annular region. The third extension 29 is configured to extend radially along the annular frame 12, such that each third extension 29 is arranged in the third region 113 in a repeating regular routing pattern, so as to fill the third region 113 with a more saturated heating element 2, thereby increasing the heating performance of the heater 10.

[0074] Please see Figure 8The diagram shown is a structural schematic of a hair dryer 100 provided in some embodiments of this application. In this embodiment, the hair dryer 100 includes a blower tube 30, a heater 10 provided according to any embodiment of this application, and an essential oil atomizing component 40. The heater 10 and the essential oil atomizing component 40 are respectively disposed within the blower tube 30, and at least a portion of the essential oil atomizing component 40 is disposed in the avoidance recess 13, thereby reducing the space occupied by the heater 10 and the essential oil atomizing component 40 within the blower tube 30. This allows the hair dryer 100 to satisfy both drying and care functions while maintaining a small size, meeting the portability requirements of the hair dryer 100.

[0075] In some embodiments, at least a portion of the essential oil storage container of the essential oil atomizing component 40 is disposed within the avoidance recess 13 to reduce the space occupied by the essential oil atomizing component 40 within the blower 30.

[0076] Figure 9 This is an exploded view of the internal structure of the ventilation duct 30. Figure 10 This is a schematic diagram of the internal structure of the ventilation duct 30. Please refer to the diagrams below. Figures 8 to 10 As shown, the hair dryer 100 also includes a handle 50 connected to the nozzle 30, an air inlet 60 located at the end of the handle 50 away from the nozzle 30, and an air outlet 70 located on the nozzle 30. The airflow of the hair dryer 100 enters through the air inlet 60, is heated by the heater 10, and is blown out through the air outlet 70 to dry and / or style the user's hair.

[0077] In some embodiments, the blower 30 is generally cylindrical, and the heater 10 is a columnar structure that matches the shape of the blower 30 for easy placement within the blower 30. The essential oil atomizing assembly 40 has an elliptical cross-section for easy installation and storage of essential oils. This cross-section is perpendicular to the airflow path of the blower 100.

[0078] In some embodiments, the essential oil storage container of the essential oil atomizing component 40 is an elongated strip extending in the airflow path direction, in order to save space occupied in the blower 30 and reduce the size of the blower 100. The clearance recess 13 is also an elongated strip extending in the airflow path direction, thus matching the essential oil storage container to better provide clearance space for the essential oil atomizing component 40.

[0079] In some embodiments, the essential oil storage container of the essential oil atomizing component 40 is detachably installed inside the blower 30, which facilitates the replacement of essential oil and improves the ease of use of the blower 100.

[0080] In some embodiments, the essential oil atomizing assembly 40 also includes an air pump located within the inner frame 122, thereby reducing the space occupied by the essential oil atomizing assembly 40 within the blower 30.

[0081] In some embodiments, the air outlet 70 includes an outlet cap for covering the columnar structure of the heater 10, and has a recessed structure at a position opposite to the avoidance recess 13 of the columnar structure, so that the avoidance recess 13 extends to the air outlet 70 in the airflow path direction, so that when at least a portion of the essential oil atomizing component 40 is accommodated in the avoidance recess 13, it can be exposed on the end face of the air outlet 70 for easy disassembly.
