Description

[Technical field]

[0001] The present invention relates to the technical field of hair dryers (home appliances), and in particular to a hair dryer that can automatically distinguish different modes. [Background technology]

[0002] Traditional hair dryer designs typically require users to manually adjust the hair dryer's mode to accommodate different blowing needs, such as hair styling, drying, and hair straightening. For non-professional users, selecting the appropriate mode can be difficult. In addition, traditional hair dryers often lack intelligent elements in their design and cannot automatically identify the air nozzle assembly replaced by the user, and therefore cannot automatically adjust to the blowing mode that is most suitable for the current air nozzle.

[0020] As will be appreciated, although the present disclosure may employ terms such as first, second, and third to describe various elements, these elements are not limited to these terms. These terms are only used to distinguish elements of the same type from one another. For example, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element, without departing from the scope of the present disclosure.

[0021] Referring to Figures 1 to 6, in some embodiments, the present invention discloses a hair dryer that can automatically distinguish between different modes.

[0022] The hair dryer includes a fan body 100 as shown in Figs. 1 to 3. In some embodiments, the outer contour of the fan body 100 is rod-shaped, S-shaped, L-shaped, or C-shaped, and is designed to accommodate various hand shapes of users. An air passage 110 is provided inside the fan body 100, and a fan 111 is provided in the air passage 110. The fan body 100 has a removable air inlet 120 that is open at one end and a first air outlet 130 that is open at the other end. The fan 111 absorbs and compresses air through the air inlet 120 at one end of the fan body 100, and then outputs high-speed air through the first air outlet 130 at the other end, thereby blowing the user's hair. The hair dryer further includes a plurality of air nozzle assemblies 200 that are detachably connected to the first air outlet 130. The air nozzle assembly may be various air nozzle assemblies such as a comb structure as shown in Fig. 4 or Fig. 5, an air nozzle that blows air, etc. The first air outlet 130 may be assembled in cooperation with air nozzles of various shapes. The detachable air inlet 120 may be various shell-like structures with engagement connection types.

[0023] 1 in conjunction with FIG. 4 or 5, the fan body 100 includes a controller 140 electrically connected to the fan 111, and a Hall sensor 150 and / or a Radio Frequency Identification (RFID) identification module 159 electrically connected to the controller 140. The controller 140 itself can set control modes for different air nozzle assemblies 200 to control the fan 111 to output wind at different speeds or to output wind at different speeds over time. The air nozzle assemblies that switch between different modes transmit signals received by the Hall sensor to the controller, and the controller controls the fan to output wind at different speeds. Referring to FIG. 6, in another embodiment, the controller 140 is electrically connected to the Hall sensor 150 and the RFID identification module 159 at the same time, or the controller 140 is electrically connected to the RFID identification module 159. Each air nozzle assembly 200 is provided with an RFID electronic tag 229 corresponding to the RFID identification module 159. Thus, the hair dryer can use the RFID identification module 159 to identify the RFID electronic tags 229 corresponding to different air nozzle assemblies 200, and output signals of different air speeds to the controller 140, or control the temperature of the heat-generating component 160 to output air of different temperatures.

[0024] 1, the air passage 110 communicates with the inlet 120 and the first outlet 130, and the position of each air nozzle assembly 200 corresponds to the position of the Hall sensor 150 and / or the RFID identification module. As shown in FIG. 4, the air nozzle assembly 200 includes a comb 210 and a first magnet 220 installed on the comb 210, the comb 210 has a second outlet 211 open, the second outlet 211 communicates with the first outlet 130, the first magnet 220 is installed corresponding to the sensing position of the Hall sensor 150, and the comb 210 is engaged and connected to the first outlet 130. At the sensing position of the Hall sensor, a magnetic signal of the first magnet 220 corresponding to the shape of the comb 210 can be obtained. In this case, the magnetic signal received by the Hall sensor is provided to the controller, which outputs a corresponding blow mode to the comb-shaped air nozzle assembly 200 .

[0025] 5, the air nozzle assembly 200 includes an air nozzle component 290, in which a third air outlet 291 is open and is connected to the second air outlet 211, and at least a part of the air nozzle component 290 is installed corresponding to the sensing position of the Hall sensor 150, and the air nozzle component 290 is engaged and connected to the first air outlet 130. This type of air nozzle component 290 itself does not have a magnetic structure, and cannot sense a magnetic signal at the sensing position of the Hall sensor, but similarly, the Hall sensor feeds back a signal to the controller, which is another type of air nozzle assembly 200, and the controller outputs a corresponding blow mode for the air nozzle assembly 200 of this type. Also, similarly, by designing magnetic components with different distances, the Hall sensor can distinguish different amounts of magnetic field to distinguish different types of air nozzle assemblies 200, and the controller can control the fan to output different air volumes. The user may also replace multiple types of air nozzle assemblies 200; or, different magnetic components may be installed in different positions in different air nozzle assemblies to correspond to the Hall sensors at different positions inside the air passage, thereby identifying and outputting different modes accordingly.

[0026] In some embodiments, the third outlet 291 has a cross-sectional area that gradually decreases from the inlet position to the outlet position of the air nozzle component 290 .

[0027] 3, the fan body 100 has a plurality of the air inlets 120 open in the circumferential direction on one side wall, and a plurality of parallel strip-shaped first air outlets 130 open on the other side wall. Air is compressed by a relatively long ventilation passage 110 at the air inlets, and a relatively high volume of air is output from the first air outlets 130 on the other side wall. Therefore, the parallel strip-shaped first air outlets 130 act on multiple points of hair on the surface of the human body, so that the blowing operation can be completed more quickly.

[0028] 1, a circuit board 141 is installed inside the air passage 110, and the controller 140 and the Hall sensor 150 are installed on the circuit board 141. A heat-generating component 160 is installed in the air passage 110 corresponding to the first air outlet 130, and the heat-generating component 160 and the fan 111 are electrically connected to the controller 140. The controller controls the heat-generating component to accommodate more types of air nozzles and can output more blowing modes.

[0029] In some embodiments, the material of the teeth of the comb 210 is metal or plastic. For example, a metal comb is advantageous for combing pet hair because pet hair is relatively hard in nature, whereas a plastic comb is easier to comb human hair because human hair is relatively soft.

[0030] Although the preferred embodiment of the present invention has been described above, the present invention is not limited to this embodiment, and any modification to the present invention falls within the technical scope of the present invention as long as it does not depart from the spirit of the present invention.
