Technical Field

[0001] This invention relates to the field of intelligent aromatherapy technology, specifically to an intelligent aromatherapy device. Background Technology

[0002] Aroma diffusers use an atomizing structure to atomize water and dissolved plant essential oils, and use a diffuser to diffuse the aroma. The aroma diffuser atomizes water and plant essential oils, keeping the surrounding environment at a high humidity level and generating a certain number of natural negative oxygen ions to purify the air. At the same time, plant essential oils have aromatherapy effects, which can help treat and relieve diseases such as influenza, high blood pressure, and bronchitis, and play a certain protective role in the nervous system, cardiovascular system and human metabolism.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0070] Please see Figure 1 and Figure 2 The present invention provides the following technical solution:

[0071] An intelligent aromatherapy device includes an aromatherapy body, which includes a base 1, a feeding structure 2, an atomizing structure 3, a housing 4, a main control unit 5, and a connecting seat 6. The feeding structure 2 and the atomizing structure 3 are provided on the top of the base 1, the main control unit 5 is provided inside the base 1, the housing 4 is threadedly connected to the base 1, and the connecting seat 6 is provided on the top of the housing 4.

[0072] Please see Figure 2 and Figure 4The feeding structure 2 includes a first motor 21, a rotating disk 22, a first connecting rod 23, a second connecting rod 24, a piston 25, a cavity 26, a diaphragm 27, a first one-way valve 28, a second one-way valve 29, a first connecting pipe 210, and a second connecting pipe 211. The output shaft of the first motor 21 is connected to the rotating disk 22. The rotating disk 22 is hinged to one end of the first connecting rod 23, and the rotating disk 22 drives the first connecting rod 23 to move eccentrically by rotating. The other end of the first connecting rod 23 is connected to the second connecting rod 24. One end of the 4 is hinged, and the other end of the second linkage rod 24 is connected to the piston 25. The piston 25 is in contact with and slidably connected to the inner wall of the cavity 26. The cavity 26 is provided with a diaphragm 27, a first one-way valve 28 and a second one-way valve 29. The first one-way valve 28 is connected to one end of the first connecting pipe 210, and the other end of the first connecting pipe 210 is connected to the connecting seat 6. The second one-way valve 29 is connected to one end of the second connecting pipe 211, and the other end of the second connecting pipe 211 is connected to the atomizing structure 3.

[0073] The first motor 21 drives the rotating disk 22 to rotate, the rotating disk 22 drives the first connecting rod 23 to move eccentrically, the first connecting rod 23 drives the second connecting rod 24 to move, and the second connecting rod 24 drives the piston 25 to slide along the inner wall of the cavity 26. When the piston 25 slides, causing the pressure in the cavity to decrease, the diaphragm 27 deforms in the direction closer to the piston 25, causing the pressure in the aromatherapy material cavity to decrease. The first one-way valve 28 opens under the pressure, and the aromatherapy material enters the aromatherapy material cavity through the first connecting pipe 210. When the piston 25 slides, causing the pressure in the cavity to increase, the diaphragm 27 deforms in the direction away from the piston 25, causing the pressure in the aromatherapy material cavity to increase. The second one-way valve 29 opens under the pressure, and the aromatherapy material enters the atomizing structure 3 through the second connecting pipe 211.

[0074] Please see Figures 2-4 The atomizing structure 3 includes a second motor 31, a stirring rod 32, an atomizing cup 33, a heating layer 34, and a fan 35; the output shaft of the second motor 31 extends into the interior of the atomizing cup 33, and this end is connected to the stirring rod 32; the atomizing cup 33 is provided with a heating layer 34 and a fan 35; one side of the atomizing cup 33 is connected to the second connecting pipe 211 in the feeding structure 2; and the top of the atomizing cup 33 is connected to the shell 4.

The stirring rod 32 rotates to stir the aromatherapy raw materials in the atomizing cup 33, making the aromatherapy raw materials more evenly distributed. The fan 35 rotates after being powered on, accelerating the diffusion of the atomized aromatherapy. The heating layer is controlled by the main control unit to heat the aromatherapy raw materials, accelerate the atomization of the aromatherapy raw materials, and realize the control of the aromatherapy concentration.

The first connecting rod 23 drives the second connecting rod 24 and the piston 25 to move. At this time, the pressure change in the cavity 26 causes the shape of the diaphragm 27 to change. When the shape of the diaphragm 27 changes towards the piston 25, the first one-way valve 28 is opened by the pressure, and the aromatherapy raw material enters the cavity through the first connecting pipe 210. When the shape of the diaphragm 27 changes away from the piston 25, the second one-way valve 29 is opened by the pressure, and the aromatherapy raw material enters the atomizing cup 33 of the atomizing structure 3 through the second connecting pipe 211, completing the addition of the aromatherapy raw material.

[0078] The main control unit 5 sends relevant instructions to control the rotation of the second motor 31 and the movement of the fan 35 in the atomizing structure 3. The rotation of the second motor 31 drives the stirring rod 32 to move, thereby realizing the stirring of the aromatherapy raw materials. At the same time, the stirring rod 32 and the fan 35 continue to move from the start device to the stop device.
