[0027] To further understand the content, features, and effects of this invention, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0028] Firstly, such as Figure 1 , Figure 2 as well as Figure 3 As shown, this invention provides an essential oil atomizing device, including an essential oil box 1, an output tube 2, a cotton wick 3, a heating wire 4, and two conductive needles 5. The essential oil box 1 has an air inlet 11 and a mist outlet 12 at both ends, and an oil storage chamber 13 is formed inside the essential oil box 1. The output tube 2 is disposed within the oil storage chamber 13, with its inlet connected to the air inlet 11 and its outlet connected to the mist outlet 12. A through hole 21 is provided on the side wall of the output tube 2, communicating with the oil storage chamber 13. The cotton wick 3 is disposed within the output tube 2, corresponding to the through hole 21. The heating wire 4 is embedded inside the cotton wick 3. Both conductive needles 5 are disposed on the essential oil box 1, and are electrically connected to the two leads of the heating wire 4.

[0029] In practical applications, the essential oil atomizing device is installed on a hair dryer with an air supply element. The outlet of the air supply element is connected to the air inlet 11, and the other end of the conductive needle 5 is electrically connected to the hair dryer. When the essential oil atomizing device is in use, the essential oil in the oil storage chamber 13 enters the output tube 2 through the through hole 21 and is absorbed by the cotton wick 3. The heating wire 4 is energized to generate heat, which atomizes the essential oil absorbed by the cotton wick 3 into essential oil mist. Under the action of the gas input into the essential oil box 1 through the air inlet 11 by the air supply element, the essential oil mist flows from the inlet side of the output tube 2 to the outlet side of the output tube 2, and is discharged from the essential oil box 1 through the mist outlet 12 to act on the hair. When the essential oil atomizing device is used up, the air supply element no longer supplies gas into the essential oil box 1 through the air inlet 11, the heating wire 4 is de-energized, and the essential oil mist that has not been discharged from the output tube 2 condenses and becomes liquid essential oil again. The liquid essential oil is absorbed again by the cotton wick 3, thereby preventing the liquid essential oil from flowing onto the surface of the hair dryer and forming oil stains, thus improving the user experience.

[0030] In some preferred embodiments, the essential oil box 1 is provided with an air tube 17 communicating with the mist outlet 12. One end of the outlet of the output tube 2 is sleeved on the air tube 17, and an absorber 9 is provided between the outlet of the output tube 2 and the air tube 17. The end of the absorber 9 away from the mist outlet 12 extends towards the inlet of the output tube 2. This technical solution ensures that after the essential oil atomizing device is used up, the liquid essential oil formed by the condensation of the essential oil mist that has not been discharged from the output tube 2 can be absorbed by the absorber 9, further preventing the liquid essential oil from flowing onto the hair dryer surface and forming oil stains. Specifically, the absorber 9 can be a sponge.

[0031] In some preferred embodiments, a retaining ring 10 is provided inside one end of the inlet of the output tube 2. The two leads of the heating wire 4 pass through the space between the outer wall of the retaining ring 10 and the inner wall of the output tube 2, and are electrically connected to the two conductive pins 5 respectively. By cooperating with the output tube 2, the retaining ring 10 effectively fixes the two leads of the heating wire 4, preventing them from contacting each other. Specifically, the two leads of the heating wire 4 can be positioned on opposite sides of the retaining ring 10.

[0032] In practical applications, the aforementioned essential oil box 1 includes a box body 14, a sealing element 15, and a cover 16. A mist outlet 12 is located at one end of the box body 14, and the other end of the box body 14 has an opening. An air pipe 17 communicating with the mist outlet 12 is located inside the box body 14. One end of the outlet of the output pipe 2 is fitted onto the air pipe 17, and a sealing ring is provided between the outlet of the output pipe 2 and the air pipe 17 to seal the gap between them. The sealing element 15 is located inside the box body 14, forming an oil storage chamber 13 between the sealing element 15 and the box body 14. A vent hole 151 is provided on the sealing element 15, and the vent hole 151 communicates with the inlet of the output pipe 2. The cover 16 is located at the opening and abuts against the seal 15. An air inlet 11 is formed on the cover 16 and communicates with the vent 151. One end of each of the two conductive pins 5 passes through the cover 16, inserts into the seal 15, and is electrically connected to the two leads of the heating wire 4. The other ends of each of the two conductive pins 5 protrude from the cover 16. Specifically, the seal 15 can be made of silicone.

[0033] In practical applications, the cover 16 and the box 14 can be detachably connected or not detachably connected.

[0034] When the cover 16 and the box 14 are detachably connected, a locking block 161 can be provided on the cover 16 and a locking hole 141 can be opened on the side wall of the box 14. The locking block 161 is locked in the locking hole 141. In this way, after the essential oil is used up, the user can remove the cover 16 to add essential oil to the oil storage chamber 13.

[0035] When the cover 16 and the box 14 are non-detachable, the essential oil in the oil storage chamber 13 is directly filled by the manufacturer during the production of the essential oil atomizing device. In this case, the essential oil atomizing device is a disposable product, that is, after the essential oil in the oil storage chamber 13 is used up, a new essential oil atomizing device needs to be replaced. In order for users to replenish the essential oil in the oil storage chamber 13 after the essential oil is used up, an oil filling hole communicating with the oil storage chamber 13 can be opened on the side wall of the box 14. A removable rubber plug is provided at the oil filling hole. After the essential oil is used up, the user can open the rubber plug to replenish the essential oil in the oil storage chamber through the oil filling hole. After replenishment, the rubber plug is then used to seal the oil filling hole.

[0036] In some preferred embodiments, the vent 151 includes a first hole 1511 and a second hole 1512. The diameter of the first hole 1511 is larger than the diameter of the second hole 1512. One end of the inlet of the output tube 2 is inserted into the first hole 1511, and the inner diameter of the output tube 2 is larger than the diameter of the second hole 1512. By designing the diameter of the first hole 1511 to be larger than the diameter of the second hole 1512 and the inner diameter of the output tube 2 to be larger than the diameter of the second hole 1512, not only can the inlet end of the output tube 2 be well limited and fixed, but the output tube 2 can also avoid obstructing the gas entering the output tube 2 through the second hole 1512, thereby achieving a better essential oil mist discharge effect. This allows the essential oil mist generated in the output tube 2 to be discharged through the mist outlet 12 for better action on the hair.

[0037] like Figure 2 , Figure 3 as well as Figure 4 As shown, in some preferred embodiments, a first oil-absorbing cotton 6 is provided between the sealing element 15 and the cover 16. The first oil-absorbing cotton 6 has a notch 61, and the air inlet 11 and the vent hole 151 both correspond to the notch. This technical solution allows the essential oil that seeps into the space between the sealing element 15 and the cover 16 through the vent hole 151 to be absorbed by the first oil-absorbing cotton 6, thus preventing leakage. Simultaneously, it also prevents the first oil-absorbing cotton 6 from obstructing the gas entering the box 14 from the air inlet 11, thereby avoiding any impact on the mist output effect of the essential oil atomizing device.

[0038] In some preferred embodiments, the essential oil container 1 is provided with a magnetic element 7, which is sleeved on the other end of the conductive needle 5. In specific applications, the hair dryer is also provided with a magnetic element 7. When the essential oil atomizing device is installed on the hair dryer, the magnetic element 7 on the essential oil container 1 and the magnetic element 7 on the hair dryer attract each other, thereby fixing the essential oil atomizing device. Specifically, both the magnetic element 7 on the essential oil container 1 and the magnetic element 7 on the hair dryer can be magnets, or one of them can be a magnet and the other can be a material that can be attracted by a magnet, such as iron.

[0039] In some preferred embodiments, a second oil-absorbing cotton 8 is provided inside the oil storage chamber 13. The second oil-absorbing cotton 8 is sleeved on the output tube 2 and corresponds to the through hole 21. In specific applications, the second oil-absorbing cotton 8 can absorb the liquid essential oil in the oil storage chamber 13. When the essential oil atomizing device is working, the liquid essential oil absorbed by the second oil-absorbing cotton 8 can diffuse to the cotton core 3 through the through hole 21. In this way, compared with only providing the cotton core 3 in the output tube 2, it can avoid leakage through the vent hole 151 after the cotton core 3 has absorbed the liquid essential oil to a saturated state.

[0040] According to one embodiment of the present invention, the outer side wall of the essential oil box 1 is provided with a protrusion 18. In practical applications, the hair dryer is provided with a groove or slot that cooperates with the protrusion 18. When the essential oil atomizing device is installed on the hair dryer, the protrusion 18 is locked in the groove or slot and cooperates with the magnetic suction member 7, which further improves the fixation of the essential oil atomizing device.

[0041] Secondly, such as Figure 5 As shown, the present invention provides a hair dryer, including a blower body 100, an air supply element on the blower body 100, and an essential oil atomizing device as described in the first aspect. The essential oil atomizing device is detachably mounted on the blower body 100, and the air outlet of the air supply element is connected to the air inlet 11. Specifically, the air supply element can be an air pump, and the outlet of the air pump is connected to the air inlet 11 through a pipe. In practical applications, after the essential oil atomizing device is used up, if the essential oil atomizing device is a disposable product, the user can remove the essential oil atomizing device from the blower body 100 and replace it with a new one. If the essential oil atomizing device is a non-disposable product, the user can remove the essential oil atomizing device from the blower body 100, add essential oil, and then reinstall it on the blower body 100.

[0042] In summary, in one or more embodiments of the present invention, the essential oil atomizing device and hair dryer of the present invention improve the misting effect by changing the structure of the essential oil atomizing device, thereby enhancing the hair care effect. Moreover, after the hair dryer is used up, the liquid essential oil condensed from the essential oil mist can be directly absorbed by the cotton core in the output tube, preventing the liquid essential oil from flowing onto the surface of the hair dryer and forming oil stains, thus improving the user experience.
