[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0020] like Figure 1 The diagram shown is a structural diagram of a heating device for an aroma diffuser provided in an embodiment of the present invention. The device includes: a heating component 2, which is located in the mounting cavity of the aroma diffuser body. The heating component 2 is provided with a heating cover 22 connected to the aroma diffuser body. A heating cavity for heating aroma diffuser materials is formed inside the heating cover 22. The heating cover 22 is provided with a limiting ring for positioning a storage cup 5 containing aroma diffuser materials. The aroma diffuser body has a flow guide cavity located above and connected to the heating component 2. The inner wall of the aroma diffuser body has several grooves 11, which are used to form airflow gaps with the emitting device inserted into the internal cavity of the aroma diffuser body.

[0021] In this embodiment of the invention, preferably, the heating device of the aroma diffuser is applicable to indoor or in-vehicle scenarios. The aroma diffuser's heating device heats the aromatherapy material in the storage cup 5, and the storage cup 5 is positioned by a limiting ring on the heating cover 22 of the heating assembly 2, placing the entire storage cup 5 within the heating chamber of the heating cover 22. This expands the heating area of ​​the storage cup 5, causing the aromatherapy material in the storage cup 5 to atomize after heating within the heating cover 22. The atomized gas diffuses into the air through the guide cavity and several grooves 11 within the aroma diffuser body. The heating chamber within the heating cover 22 heats the storage cup 5 and the aromatherapy material within it, without directly connecting the aroma diffuser's heating device to the storage cup 5 containing the aromatherapy material. Instead, the storage cup 5 containing aromatherapy materials is placed inside the heating chamber, where the heating cover 22 heats the aromatherapy materials in the storage cup 5, achieving smokeless combustion and carbonization, allowing the aromatherapy materials in the storage cup 5 to release fragrance. At the same time, the airflow chamber of the aromatherapy diffuser body located above the heating component 2 allows the atomized aromatherapy gas to diffuse from the airflow chamber. The groove 11 on the inner wall of the aromatherapy diffuser body and the diffuser device inserted into the aromatherapy diffuser body form an airflow gap, which facilitates the diffusion of the atomized gas into the air through the diffuser device. The separate design of the aromatherapy diffuser's heating device and the storage cup 5 containing aromatherapy materials makes it easy to remove the storage cup 5, while avoiding direct connection between the storage cup 5 and the heating cover 22, which could damage the storage cup 5 used to hold aromatherapy materials after long-term use and affect the atomization effect.

[0022] Preferably, the diffuser inserted into the main body of the aroma diffuser may include a breathable cover 3, a connecting bracket 4, and a storage cup 5. One end of the hollow cylindrical connecting bracket 4 is connected to the hollow breathable cover 3, and the other end is detachably connected to the storage cup 5 through a connecting component. When the diffuser is inserted through the guide cavity of the main body of the aroma diffuser, the storage cup 5 may be positioned by a limiting ring on the heating cover 22 and the storage cup 5 is placed in the heating cavity. The connecting bracket 4 is placed in the guide cavity, and an airflow gap is formed between the groove 11 and the outer wall of the connecting bracket 4. The heated and atomized aroma is guided and diffused by the air passage inside the breathable cover 3 and the connecting bracket 4, and diffused out along the airflow direction.

[0023] In one embodiment of this utility model, a heating component 2 is provided in the mounting cavity of the main body of the aroma diffuser. The heating chamber in the heating cover 22 of the heating component 2 heats the aroma material in the storage cup 5. The heating cover 22 is a semi-enclosed structure. The storage cup 5 is placed in the heating chamber of the heating tank and the storage cup 5 containing the aroma material is restricted by a limiting ring. The heating cover 22, which is fitted over the storage cup 5, heats the aroma material in the storage cup 5, so that the aroma material in the storage cup 5 is heated evenly and the storage cup 5 is easy to remove and put away. A guide cavity is provided in the main body of the aroma diffuser. The guide cavity is connected to the heating chamber of the heating component 2 below to facilitate the upward diffusion of the aroma material after atomization. At the same time, the airflow gap formed between the groove 11 on the inner wall of the aroma diffuser and the dispersing device facilitates the diffusion of the scent. The limiting ring restricts the position of the storage cup 5 so that the heating tank can heat the aroma material in the storage cup 5. The storage cup 5 can be removed during use. The split design can avoid damage to the storage cup 5 or even affect the atomization effect due to the inability to disassemble it.

[0024] like Figure 1-8 As shown, in a preferred embodiment of the present invention, the aroma diffuser body includes a shell 1, the shell 1 is connected to and sleeved on the mounting shell 12, a first mounting cavity is formed between the shell 1 and the mounting shell 12, the heating component 2 is connected to the first baffle at the bottom of the mounting shell 12 and is located in the first mounting cavity, the mounting shell 12 is a hollow structure and the internal cavity is connected to the heating cavity of the heating cover 22.

The diffuser is inserted into the aroma diffuser body and the storage cup 5 is placed in the heating cavity inside the semi-enclosed heating cover 22, so that the aroma material in the storage cup 5 is heated by the heating cavity, so that the aroma material is atomized to form smoke, which is guided and diffused into the air through the vent 3 and the cavity inside the connecting bracket. The first detection element 23 is also installed on the outer wall of the fixing frame 21, and the first detection element 23 is used to detect... The temperature of the heating cover 22 inside the fixing frame 21 is measured. The heating cover 22 can be a ceramic heating ring. The heating cover 22 is heated to the corresponding temperature by the power supply device connected to the fixing frame 21, thereby heating the storage cup 5 and the aromatherapy material in the storage cup 5 located in the heating chamber. The fixing frame 21 can be a shell that provides structural support and insulation protection for the heating cover 22. The temperature of the heating cover 22 is detected by a temperature detection sensor so that the temperature of the heating cover 22 can be controlled by the power supply device. The heating principle of the heating cover 22 can be that the resistance heat generated by the current passing through the PTC ceramic can be quickly and evenly transferred to the air in the heating chamber, thereby heating the aromatherapy material in the storage cup 5 more evenly and avoiding the aromatherapy material sticking to the inside of the storage cup 5 due to uneven heating.
