[0026] To further understand the content, features, and effects of this utility model, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0027] Please refer to Figure 1 , Figure 2 as well as Figure 3This utility model provides a hair dryer, comprising: a housing 10, an air-guiding component 20, a first control board 30, a heating element 40, a second control board 50, and an essential oil atomizing device 60. The housing 10 has an air inlet 101 and an air outlet 102. A partition plate 103 is provided on the inner wall of the housing 10, dividing the interior of the housing 10 into a first cavity 104 and a second cavity 105, both of which are connected to the air inlet 101 and the air outlet 102. The air-guiding component 20, the first control board 30, and the heating element 40 are sequentially arranged in the first cavity 104, located between the air inlet 101 and the air outlet 102. The first control board 30 is electrically connected to the air-guiding component 20 and the heating element 40. The second control board 50 is arranged in the second cavity 105 and is electrically connected to the first control board 30. The essential oil atomizing device 60 is mounted on the housing 10 and electrically connected to the first control board 30. The mist outlet 6012 of the essential oil atomizing device 60 is located on one side of the air outlet 102.

[0028] In practical application, the user holds the hair dryer housing 10 with the air outlet 102 and the essential oil atomizing device 60 facing the hair. The user starts the hair dryer using a button on the housing 10 that is electrically connected to the first control board 30 and the second control board 50. The air intake 20 draws outside air into the housing 10 through the air inlet 101, where it is then divided by the partition plate 103. Part of the air enters the first chamber 104 and passes through the second control board 50, carrying away the heat generated by the second control board 50 and cooling it. The remaining air passes through the heating element 40 in the second chamber 105 and is then blown onto the hair through the air outlet 102 to dry it. Simultaneously, the essential oil mist atomized by the essential oil atomizing device 60 is blown onto the hair surface through the mist outlet 6012, conditioning the hair and making it smoother and shinier after drying. Specifically, the air intake 20 can be a fan, and the heating element 40 can be a heating wire.

[0029] In some preferred embodiments, the housing 10 has a recess 106 recessed into its interior, corresponding to the outlet of the second chamber 105, and the essential oil atomizing device 60 is disposed within the recess 106. This design allows the airflow from the first chamber 104 to pass over the outer wall of the recess 106, carrying away the heat transferred to the outer wall of the recess 106 during operation of the essential oil atomizing device 60. Furthermore, since the essential oil atomizing device 60 is installed within the recess 106 and does not protrude from the housing 10, this improves the aesthetics of the hair dryer and reduces its size.

[0030] In practical applications, the aforementioned housing 10 is provided with a mounting member 70, which has a recess 106. The outer side wall of the mounting member 70 has an outwardly protruding mounting ridge 701, and the inner side wall of the housing 10 has a mounting groove 107 that matches the shape of the mounting ridge 701. The mounting ridge 701 is located within the mounting groove 107. This technical solution facilitates the assembly of the mounting member 70 and the housing 10. Specifically, the housing 10 can be composed of two interlocking outer shells.

[0031] like Figure 4 As shown, in some preferred embodiments, the essential oil atomizing device 60 includes an essential oil box 601, an output tube 602, a cotton wick 603, a heating element 604, and a conductive needle 605. The essential oil box 601 is disposed within a recess 106, and its two ends have an air inlet 6011 and a mist outlet 6012, respectively. The air inlet 6011 communicates with a vent hole 1061 formed in the side wall of the recess 106. The output tube 602 is disposed within the essential oil box 601, with its inlet connected to the air inlet 6011 and its outlet connected to the mist outlet 6012. A through hole 6021 is provided in the side wall of the output tube 602, communicating with the interior of the essential oil box 601. The cotton wick 603 is disposed within the output tube 602, corresponding to the through hole 6021. The heating element 604 is embedded within the cotton wick 603. One end of the conductive needle 605 extends into the essential oil box 601 and is electrically connected to the heating element 604, while the other end of the conductive needle 605 protrudes from the essential oil box 601. The side wall of the recess 106 is provided with a conductive rod 80 that is electrically connected to the second control board 50, and the conductive rod 80 is electrically connected to the conductive needle 605. Specifically, the heating element 604 may be a heating wire.

[0032] In practical application, the essential oil atomizing device 60 is activated by a button on the housing 10 that is electrically connected to the second control board 50. The essential oil in the essential oil box 601 enters the output tube 602 through the through hole 6021 and is absorbed by the cotton wick 603. The heating element 604 is energized to generate heat, which atomizes the essential oil absorbed by the cotton wick 603 into essential oil mist. Under the action of the gas input into the essential oil box 601 through the air inlet 6011, the essential oil mist flows from the inlet side to the outlet side of the output tube 602, and is discharged from the essential oil box 601 through the mist outlet 6012 to act on the hair. When the essential oil atomizing device 60 is used up, gas is no longer introduced into the essential oil box 601 through the air inlet 6011, the heating element 604 is de-energized, and the essential oil mist that has not been discharged from the output tube 602 condenses and becomes liquid essential oil again. The liquid essential oil is absorbed again by the cotton wick 603, thus preventing the liquid essential oil from flowing onto the surface of the hair dryer and forming oil stains, improving the user experience.

[0033] Specifically, the essential oil box 601 is provided with an air pipe 6014 that communicates with the mist outlet 6012. One end of the outlet of the output pipe 602 is sleeved on the air pipe 6014. A sealing ring is provided between the outlet of the output pipe 602 and the air pipe 6014. The essential oil box 601 is provided with a sealing element 6015. An oil storage cavity is formed between the sealing element 6015 and the essential oil box 601. The sealing element 6015 is provided with an air passage hole 60151 that communicates with the inlet of the output pipe 602. One end of the conductive needle 605 passes through the essential oil box 601, inserts into the sealing element 6015, and is electrically connected to the heating element 604. The other end of the conductive needle 605 protrudes from the essential oil box 601. The air passage 6014 engages with the air vent 60151 on the seal 6015 to effectively limit and fix the output pipe 602 in its axial direction, preventing liquid essential oil in the oil storage chamber from entering the output pipe 602 through the inlet or outlet. In practical applications, the seal 6015 can be made of silicone.

[0034] It is understandable that the gas entering the essential oil box 601 through the air inlet 6011 can be the gas introduced into the housing 10 by the air guide 20 when the hair dryer is working, and then enters the output pipe 602 through the vent 1061 and the air inlet 6011.

[0035] To achieve a better essential oil mist effect, in some preferred embodiments, the essential oil atomizing device 60 further includes an air supply component 607. The air supply component 607 is disposed within the housing 10 and electrically connected to the second control board 50. The air outlet of the air supply component 607 is connected to the vent 1061. This technical solution allows the essential oil mist generated in the output tube 602 to be discharged from the essential oil box 601 through the mist outlet 6012 under the action of the air supply component 607, thus acting on the hair and achieving a better essential oil mist effect, further improving the hair care effect. Furthermore, this design allows the essential oil atomizing device 60 to be individually controlled via a button on the housing 10 electrically connected to the second control board 50. Even when the air intake component 20 is not working, the essential oil atomizing device 60 can still blow out essential oil mist under the action of the air supply component 607, thereby meeting different user needs. Specifically, the air supply component 607 can be an air pump.

[0036] In some preferred embodiments, the essential oil box 601 is provided with a first magnetic member 606, and a second magnetic member 90 is provided in the recess 106. When the essential oil box 601 is placed in the recess 106, the first magnetic member 606 and the second magnetic member 90 attract each other. This technical solution ensures that when the essential oil box 601 is installed in the recess 106, the mutually attracting first magnetic member 606 and second magnetic member 90 can effectively fix the essential oil box 601. Specifically, both the first magnetic member 606 and the second magnetic member 90 can be magnets, or one can be a magnet and the other can be a material that can be attracted by a magnet, such as iron.

[0037] In some preferred embodiments, the essential oil box 601 is provided with a first protrusion 6013, and the inner sidewall of the recess 106 is provided with a second protrusion 702. When the essential oil box 601 is placed in the recess 106, the first protrusion 6013 and the second protrusion 702 are engaged. This technical solution further improves the firmness of the essential oil box 601 when it is installed in the recess 106.

[0038] In some preferred embodiments, the housing 10 is provided with a mounting block 100 located inside the air outlet 102, and a third magnetic element 110 is provided on the mounting part. This technical solution allows hair styling accessories, such as straighteners or nozzles, to be magnetically connected to the air outlet 102 of the hair dryer, thereby expanding the applicability of the hair dryer. Specifically, the third magnetic element 110 can be a magnet or iron.

[0039] In some preferred embodiments, the first cavity 104 is provided with an air distribution component 120, which is located between the heating element 40 and the air outlet 102. The side of the air distribution component 120 facing the heating element 40 has an air distribution arc surface. This technical solution ensures that when the hair dryer is working, the airflow flowing from the first cavity 104 and the second cavity 105 to the air outlet 102 is evenly distributed under the action of the air distribution arc surface before being blown out from the air outlet 102. Compared to concentrated airflow, this not only results in a more stable airflow but also reduces friction between airflows and lowers noise.

[0040] In some preferred embodiments, the hair dryer further includes an ion generator 130, which is disposed within the housing 10 and electrically connected to the first control board 30. The discharge brushes of the ion generator 130 correspond to the air outlet 102. In specific applications, the ion generator 130 has two discharge brushes, which are arranged opposite each other within the air outlet 102. The two discharge brushes can generate positive ions and negative ions respectively. Positive ions can sterilize and purify the air, while negative ions can neutralize static electricity, making hair easier to comb.

[0041] In summary, in one or more embodiments of this utility model, the hair dryer of this utility model divides the interior of the housing into a first cavity and a second cavity by means of a partition, and the second control board is set in the second cavity, so that the cold air entering the housing under the action of the air guide can cool the second control board in the second cavity, thereby preventing the second control board from getting too hot and affecting normal use.

[0042] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
