[0028] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details:

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, an aromatherapy diffuser includes a main unit 1, an aromatherapy chamber cover 2 detachably connected to the main unit 1, and a liquid storage tank 3 sealed to the aromatherapy chamber cover 2 by threads or snaps. The liquid storage tank 3 is used to store aromatherapy liquid. The liquid storage tank 3 is connected to the aromatherapy chamber cover 2 by threads or snaps, making it easy to remove the liquid storage tank 3 for replenishing the aromatherapy liquid. A sealing ring 19 is provided at the upper port of the liquid storage tank 3 to achieve a seal at the upper port of the liquid storage tank 3.

[0031] like Figure 2 and Figure 6As shown, the host 1 has a housing 4. The host 1 includes a display screen 5 disposed in or embedded in the housing 4, and a liquid level detection component 6 disposed inside the housing 4. The liquid level detection component 6 is electrically connected to the display screen 5. The liquid level detection component 6 includes a circuit board 601, a plurality of electrode springs 602 fixedly disposed on the circuit board 601, electrode plates 603 in contact with the electrode springs 602, and a touch panel 604. When there are multiple electrode springs 602, each electrode spring 602 is arranged sequentially along the height direction of the liquid storage tank 3; the number of electrode plates 603 is the same as that of the electrode springs 602, and they are arranged one-to-one. The liquid storage tank 3 is made of a material with capacitive touch effect, such as sodium silicate glass, metallic copper, metallic aluminum, boron nitride, etc. The outer side of the touch panel 604 is in contact with the outer wall of the liquid storage tank 3, forming a capacitive touch effect. The size of the electrode plate 603 covers the touch sensing area. When the liquid level in the liquid storage tank 3 reaches the corresponding touch sensing area, the display screen 5 displays the current liquid level information. The size of the electrode plate 603 is larger than the diameter of the electrode spring 602, so that the electrode plate 603 completely covers the electrode spring 602. The larger size of the electrode plate 603 also makes it easier to increase the area of ​​the touch sensing area and the sensing accuracy.

[0032] Therefore, the liquid level detection component 6 is used to detect the amount of aromatherapy liquid stored in the storage tank 3, and the display screen 5 is used to display the real-time storage data detected by the liquid level detection component 6. If four electrode plates 603 are evenly arranged vertically, the display screen 5 will display four liquid level data: 25%, 50%, 75%, and 100%, with 25% being the lowest liquid level. If ten electrode plates 603 are evenly arranged vertically, the display screen 5 will display ten liquid level data: 10%, 20%...90%, and 100%, with 10% being the lowest liquid level.

[0033] like Figure 1 and Figure 2 As shown, the housing 4 also houses an air pump 7, a battery 8, and a control board 20. The air pump 7 and battery 8 are electrically connected to the control board 20, and the battery 8 supplies power to the various electrical components. A support base 14 is located at the lower end of the housing 4, and both the battery 8 and control board 20 are mounted on the support base 14. The battery 8 is a rechargeable battery, and the support base 14 has a charging port 15 for charging the battery 8. When the display screen 5 is located inside the housing 4, it is vertically mounted on the control board 20. The housing 4 has an opening corresponding to the position of the display screen 5, matching its shape and size, and an observation window 16 made of transparent material is provided within the opening.

[0034] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 7As shown, an atomizing component 9 is provided in the aromatherapy chamber cover 2, and an atomizing outlet 201 communicating with the atomizing component 9 is provided at the upper end of the aromatherapy chamber cover 2. The atomizing component 9 includes an atomizing nozzle 901 and a connecting tube 902. A liquid suction tube 11 is inserted into the connecting tube 902 and inserted into the liquid storage tank 3. An outlet 903 communicating with the liquid suction tube 11 is provided on the connecting tube 902. The outlet 903 is close to the atomizing nozzle 901. The diameter of the atomizing nozzle 901 is set to 0.1-0.5cm to make the air pressure stronger. An inner cavity shell 17 is provided at the upper end of the outer shell 4. The upper end of the inner cavity shell 17 is open and has a placement cavity for placing the liquid storage tank 3. A through hole structure communicating with the placement cavity and allowing the touch panel 604 to pass through is provided on the side wall of the inner cavity shell 17. The air pump 7 has an air outlet pipe 10 connected to its outlet end, and the inner cavity shell 17 has a plug-in interface 18 at its upper end, with the air outlet pipe 10 connected to the plug-in interface 18. The atomizing assembly 9 also includes an air inlet pipe 904, which is inserted into the plug-in interface 18, so that the air outlet pipe 10 is connected to the interior of the atomizing assembly 9.

[0035] like Figure 3 and Figure 4 As shown, a second magnetic 12 is provided at the upper end of the inner cavity shell 17, and a first magnetic 13 is provided at the lower end of the aromatherapy chamber cover 2. When the air inlet tube 904 is inserted into the plug-in interface 18, the second magnetic 12 and the first magnetic 13 attract each other magnetically, making the aromatherapy chamber cover 2 easy to install and remove and able to be stably mounted on the upper end of the inner cavity shell 17.

[0036] The working principle of this invention is as follows: When the air pump 7 is activated, the air pressure generated by the air pump 7 enters the atomizing component 9 through the air outlet pipe 10, the connector 18, and the air inlet pipe 904, creating a negative pressure state within the connected liquid storage tank 3. Simultaneously, the aromatherapy liquid in the liquid storage tank 3 enters the connecting pipe 902 through the suction pipe 11 and is discharged from the liquid outlet 903. The atomizing nozzle 901 is connected to the air outlet of the air pump 7. After the aromatherapy liquid is discharged from the liquid outlet 903, it is atomized under the pressure and discharged through the atomization outlet 201. The basic principle of this atomization process is Bernoulli's principle, which is existing technology and will not be elaborated further.

[0037] In summary, this utility model includes a display screen 5 and a liquid level detection component 6. The liquid level detection component 6 can detect the amount of aromatherapy liquid stored in the storage tank 3, and the display screen 5 can display the real-time storage volume data detected by the liquid level detection component 6. This allows users to know the liquid level of the aromatherapy liquid in a timely and accurate manner, facilitating timely addition of aromatherapy liquid. The touch panel 604 of the liquid level detection component 6 elastically abuts against the outer wall of the storage tank 3 through an electrode spring 602, forming an elastic contact with the storage tank 3, improving the contact effect and detection accuracy, and can be used with storage tanks 3 of various diameters.

[0038] The above are merely preferred embodiments of this utility model and are 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, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
