[0030] As shown in Figure 1 and Figure 2 The present application embodiment provides a kind of aromatherapy machine, including: shell 20, main body 10, smoke generation component 30 and dispersing fragrance fan 40.Therein, main body 10 includes the lower main body 11 and upper main body 13 connected with each other, shell 20, upper main body 13 and lower main body 11 are enclosed to form smoke cavity 21 together.Therein, upper main body 13 and lower main body 11 as Figure 2The upper body 13 is arranged above the lower body 11 in the up-down position connection. The smoke generating assembly 30 is arranged in the upper body 13, the fragrance fan 40 is arranged in the lower body 11, and the smoke cavity 21 is arranged outside the upper body 13 and the lower body 11. The main body 10 is provided with a smoke outlet channel 134, which is connected with the smoke generating assembly 30 and the smoke cavity 21. The arrangement of the main body 10 is compact, the height is reduced, and the aroma diffuser is suitable for use in the automobile center console. The main body 10 is provided with a wind guide channel 12, which is connected with the air outlet of the fragrance fan 40 and the smoke cavity 21. The wind guide channel 12 is provided with a blowing port 133 connected with the smoke cavity 21, and the blowing port 133 is arranged on the upper body 13. The aroma diffuser is provided with a fragrance outlet 60 connected with the smoke cavity 21. The fragrance fan 40 is used to blow air into the smoke cavity 21 through the blowing port 133, so that the smoke in the smoke cavity 21 is diffused from the fragrance outlet 60.

[0031] The shell 20 is made of transparent material or has a transparent viewing window, and is preferably made of translucent material, so that the user can observe the shape of the smoke in the smoke cavity 21 in all directions. The shell 20 can be a ring-shaped shell surrounding the main body 10. The fragrance outlet 60 is located at the top of the main body 10 (see Figure 1 and Figure 2 ) or the shell 20 is arranged separately from the main body 10 to form the fragrance outlet 60 (see Figure 6 ).

[0032] The smoke generating assembly 30 includes a fragrance material, a heating element or an ultrasonic atomizer, etc. The fragrance material is mainly a liquid storage cotton containing fragrance essential oil. When the smoke generating assembly 30 works, the fragrance essential oil can be heated or ultrasonic atomized to generate liquid smoke. The liquid smoke enters the smoke cavity 21 from the smoke outlet 132 of the smoke outlet channel 134.

[0033] In a specific embodiment, the lower body 11 further includes a base 111 and a flow guide 112 arranged on one side of the base 111 facing the upper body 13. The flow guide 112 and the base 111 form an electronic device mounting cavity 115. The electronic device mounting cavity 115 is used to arrange electronic components such as batteries, and in some embodiments, the fragrance fan 40 is arranged in the electronic device mounting cavity 115. When using the aroma diffuser, the base 111 is usually placed on a flat surface such as a table. The flow guide 112 has the functions of smoke flow guide and isolation. The shape of the flow guide 112 can be designed according to the required smoke shape or the required space shape of the electronic device mounting cavity 115. For example, the flow guide 112 can be arranged as Figure 2 and Figure 3The tapering structure shown, which gradually decreases in width in a direction gradually away from the base 111, not only shapes the smoke into a mountain shape, but also provides sufficient volume for the electronic device mounting cavity 115. In some embodiments, the smoke outlet 132 of the smoke outlet passage 134 is arranged towards the flow guide 112, so that the smoke flows along the flow guide 112, ensuring the effect of the smoke shaping.

[0034] The air inlet of the fragrance fan 40 is in communication with the outside air, and the fragrance fan 40 can blow air flow into the smoke chamber 21 when working, and the air flow can be blown out of the fragrance outlet 60. The smoke liquid in the smoke chamber 21 is carried out of the smoke chamber 21 by the air flow blown out by the fragrance fan 40, which can enhance the fragrance effect and prevent the smoke liquid from being deposited in the smoke chamber 21 to form liquid accumulation, thereby ensuring the aesthetics of the smoke chamber 21. In addition, the air outlet 133 is located on the upper body 13, and the air outlet 133 is located above the lower body 11, that is, the air outlet 133 is arranged relatively high. Even if part of the smoke liquid is deposited in the smoke chamber, it will not enter the inside of the lower body 11 (such as the electronic device mounting cavity 115) through the air outlet 133, which can prevent the smoke liquid from corroding the fragrance fan 40 and other electronic components in the electronic device mounting cavity 115.

[0035] In some embodiments, the air outlet 133 is located at one end of the upper body 13 close to the lower body 11, that is, the air outlet 133 is arranged as low as possible on the upper body 13, which can prevent liquid accumulation from entering the lower body 11 while more efficiently carrying the smoke that has sunk to the bottom of the smoke chamber 21 out of the smoke chamber 21. In some embodiments, the air outlet 133 is arranged towards the shell 20. The shell 20 is arranged around the main body 10, so that the air outlet 133 is arranged towards the outside. According to the Figure 2 The air outlet 133 is arranged towards the right side (in the radial direction of the upper body 13). Arranging the air outlet 133 towards the shell 20 can avoid damaging the mist shaping while ensuring the air blowing effect.

[0036] In some embodiments, referring to Figure 3 A first connecting column 113 is arranged between the upper body 13 and the lower body 11, and the upper body 13 and the lower body 11 are fixedly connected, for example, by the first connecting column 113. Referring to Figure 2The air guide channel 12 comprises a first channel 121 arranged in the first connecting column 113 and a second channel 122 arranged in the upper body 13, and the first channel 121 and the second channel 122 are connected at a preset angle.

In some embodiments, the first channel 121 and the second channel 122 are connected vertically, and the preset angle is 90 degrees. The first channel 121 guides the air blown by the fragrance fan 40 from the lower body 11 to the second channel 122, and the second channel 122 guides the air flow in the horizontal direction, so that the air flow is blown into the smoke chamber 21 in the horizontal direction. For example, refer to Figure 3 The fragrance fan 40 is arranged in the electronic device mounting cavity 115, and the top of the air guide member 112 is provided with the first connecting column 113. Refer to Figure 4 and Figure 5 The upper body 13 is provided with a connecting through hole 135, and one end of the first connecting column 113 is arranged in the connecting through hole 135, so as to connect the vertical first channel 121 and the horizontal second channel 122 through the connecting through hole 135. The air flow blown by the fragrance fan 40 enters the first channel 121 through the second channel 122, and is finally blown out from the air outlet 133.

[0037] In some embodiments, the upper body 13 is connected to the air guide member 112 as a whole through the connecting member 15. The first connecting column 113 is connected to the upper body 13 through the connecting member 15. In some embodiments, the connecting member 15 is provided with a receiving space, and the control circuit board 16 can be arranged in the receiving space of the connecting member 15. The control circuit board 16 is electrically connected to the fragrance fan 40 and the smoke generating assembly 30, for example. The air guide member 112 is further provided with a channel through which the connecting wires between the control circuit board 16 and the fragrance fan 40 pass.

[0038] In some embodiments, the second channel 122 is arranged to be inclined towards the direction gradually approaching the air outlet 133 and the base 111. According to the orientation shown in Figure 2 , the second channel 122 is slightly inclined downward along the air outlet direction, so that the air flow blown out from the air outlet 133 can first be blown downward towards the lower body 11 under the guidance of the second channel 122, and then reach the fragrance outlet 60. The air flow blown by the fragrance fan 40 can as far as possible drive the smoke at the bottom of the smoke chamber 21, so as to enhance the smoke dispersing effect and more effectively prevent the accumulation of liquid at the bottom of the smoke chamber 21.

[0039] In some embodiments, the width of the second channel 122 gradually increases along the direction gradually approaching the air outlet 133. In some embodiments, refer to Figure 4 and Figure 5The second channel 122 is in the shape of a sector, can diffuse the airflow entering from the connecting through hole 135 and then blow out, so that the airflow blown into the smoke cavity 21 is diffused more uniformly, and the airflow in the smoke cavity 21 can be blown out from the incense outlet 60 more uniformly.

[0040] The incense machine further comprises an air inlet fan 50, and an air outlet of the air inlet fan 50 is in communication with the smoke generating assembly 30. The air inlet of the air inlet fan 50 is in communication with external air, and is used to suck air into the smoke generating assembly 30, so that the smoke generated by the smoke generating assembly 30 is brought into the smoke outlet 132.

[0041] In some embodiments, referring to Figure 2 , the air inlet fan 50 and the smoke generating assembly 30 are provided with an air inlet channel 1141 that guides air of the air inlet fan 50 and the smoke generating assembly 30. In some embodiments, the air inlet fan 50 is arranged in the lower main body 11, for example, the air inlet fan 50 is arranged in the electronic device mounting cavity 115. Referring to Figure 3 , the lower main body 11 and the upper main body 13 are provided with a second connecting column 114, and the air inlet channel 1141 is at least partially arranged in the second connecting column 114. The smoke generating assembly 30 is arranged in the upper main body 13, the airflow blown out by the air inlet fan 50 is blown upwards to the smoke generating assembly 30 through the air inlet channel 1141, the smoke generated by the smoke generating assembly 30 is then sunk to the smoke outlet 132 along the surface of the flow guide 112, so as to shape the smoke. The air inlet fan 50 is arranged in the lower main body 11, which can reduce the occupation of the space on the top of the main body 10, and can fully utilize the space below the flow guide 112 (i.e., the electronic device mounting cavity 115), so that the incense machine has a smaller volume and a more compact structure.

[0042] In some embodiments, referring to Figure 6 , the air inlet fan 50 is arranged in the upper main body 13, and the air inlet channel 1141 is arranged in the upper main body 13. For example, the air inlet fan 50 is arranged in a cavity adjacent to the smoke generating assembly 30, which can shorten the distance between the outlet of the air inlet fan 50 and the smoke generating assembly 30, and ensure the air inlet effect.
