Description

Technical Field

[0001] This utility model relates to the field of electronic devices, and in particular to an aroma diffuser. Background Technology

[0002] While aroma diffusers are widely used in homes, vehicles, and public places, they still have the following shortcomings: 1. The airflow generated by a fan diffuses the aroma, resulting in a relatively large size. 2. A few aroma diffusers use ultrasonic atomizers to diffuse the aroma. Essential oils are dripped onto the atomizer through a hose, and then powered on to activate it. The essential oils are atomized and sprayed outwards. However, these diffusers have complex structures and require a motor to facilitate oil flow, increasing both complexity and cost. 3. Aroma diffusers have a limited operating mode. Most can only be manually turned on or off. When installed in a vehicle, keeping it on results in wasted essential oils, and turning it on when getting in and off when getting out is cumbersome. 4. The outer shell of the aroma diffuser is connected to multiple internal components. When aesthetics become tiresome, it's necessary to replace the shell with a different pattern or material, which is also cumbersome. Utility Model Content

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: Please see Figures 1 to 4 An aroma diffuser includes a housing 1 and an ultrasonic atomizer 2 disposed within the housing 1, a bottle 4 with a liquid guide rod 3, a positioning partition 5, an upper shell 6, a lower shell 7, a protective cover 8, a main control circuit board 9, a negative ion generator 10, a charging interface 11, a battery 12, a first switch 13 for setting the spray interval time of the aroma diffuser, and a second switch 14 for setting the working mode of the aroma diffuser.

[0020] The outer casing 1 includes a base 15 and an upper cover 16 with a window. The upper cover 16 is located above the positioning partition 5; simply placing the upper cover 16 on top of the positioning partition 5 is sufficient. The base 15 is located below the positioning partition 5, and the lower casing 7 is detachably and fixedly connected to the base 15, for example, by screws or other fasteners. When it is necessary to replace the outer casing 1, simply open the upper cover 16 and remove the base 15, making replacement of the outer casing 1 more convenient.

[0021] The upper shell 6 is detachably fixed above the positioning partition 5. Exemplarily, the upper shell 6 and the positioning partition 5 are fixed by a rotating snap-fit ​​mechanism. Specifically, the bottom edge of the inner wall of the upper shell 6 has a slot, and the middle of the positioning partition 5 has a boss 17. The outer edge of the boss 17 has a protrusion 18 that matches the slot. The protrusion 18 slides into the slot to fix the upper shell 6 to the positioning partition 5. The top of the upper shell 6 has a mist outlet 19, and the window and the mist outlet 19 are correspondingly arranged. The ultrasonic atomizer 2 is fixed at the mist outlet 19 and abuts against the liquid guide rod 3. A protective cover 8 is also provided above the ultrasonic atomizer 2. The protective cover 8 is located inside the window and snaps onto the upper shell 6. The center of the protective cover 8 has a V-shaped diffuser, through which the atomized essential oil diffuses into the air.

[0022] The lower shell 7 is fixed below the positioning partition 5, for example, by means of fasteners such as screws. The negative ion generator 10 and the main control circuit board 9 are fixed inside the cavity of the lower shell 7.

[0023] The bottle 4 can be used to hold essential oils. The bottle 4 is located inside the upper shell 6 and is detachably connected to the upper shell 6. For example, the outer wall of the bottle 4's opening is threaded to the upper shell 6. The bottle 4's opening is equipped with a sealing cap to prevent the essential oil from leaking out. The liquid guide rod 3 can be an absorbent cotton swab. The tip of the liquid guide rod 3 passes through the sealing cap and abuts against the ultrasonic atomizer 2. The essential oil at the tip of the liquid guide rod 3 forms a mist under the action of the ultrasonic atomizer 2 and diffuses outwards. When the bottle 4 is relatively tall, the following implementation method can be used: a through hole for the bottle 4 is provided in the center of the positioning partition 5, allowing the lower part of the bottle 4 to be inserted into the lower shell 7, thus reducing the overall height of the aromatherapy diffuser.

[0024] The positioning partition 5 is a light guide plate, and the main control circuit board 9 is fixed to the lower surface of the positioning partition 5. The main control circuit board 9 is equipped with multiple LED lights, and the LED light circuit is shown in the figure. The outer shell 1 is light-transmitting, which allows the aroma diffuser to be used as a night light and provides a better visual experience.

[0025] The outer shell 1 is made of ceramic, which can enhance the texture of the aroma diffuser.

[0026] Please see Figure 12 The main control circuit board 9 is electrically connected to the ultrasonic atomizer 2, the negative ion generator 10, the charging interface 11, the battery 12, the first switch 13, and the second switch 14. The battery 12 can be disposed in the cavity formed between the upper shell 6 and the upper cover 16 and fixed on the positioning partition 5. Specifically, the main control circuit board 9 mainly includes a microcontroller 20, a vibration sensor 21, and a battery charging circuit 22. The charging interface 11 is connected to the battery 12 through the battery charging circuit 22. The ultrasonic atomizer 2, the vibration sensor 21, the negative ion generator 10, the first switch 13, and the second switch 14 are all electrically connected to the microcontroller 20. The microcontroller circuit is as follows: Figure 5 As shown, the driving circuit of the ultrasonic atomizer 21 is as follows: Figure 6 As shown, the interface circuit of the negative ion generator 10 is as follows: Figure 7 As shown, the start / stop circuit of the vibration sensor 21 is as follows: Figure 8 As shown, KEY1 HX_1210_C06 is the vibration sensor 21. The battery charging circuit 22 is as follows... Figure 9 As shown, the circuit diagram of the first switch 13 is as follows: Figure 10 As shown, the circuit diagram of the second switch 14 is as follows: Figure 11 As shown. The battery 12 supplies power to the various electronic components inside the aroma diffuser.

[0027] Since the main control circuit board 9 is located below the positioning partition 5, while the battery 12 and the ultrasonic atomizer 2 are located above the positioning partition 5, two sets of conductive pins 23 are provided on the main control circuit board 9. Each set of conductive pins 23 passes through the positioning partition 5. One set of conductive pins 23 is connected to the ultrasonic atomizer 2 through a wire, and the other set of conductive pins 23 is connected to the battery 12 through a wire.

[0028] The main control circuit board 9 can also be powered by an external power source.

[0029] This utility model allows the following operations to be performed by simply setting up the program and writing the corresponding code into the microcontroller 20: First, the aroma diffuser is set to three working modes: "Off Mode", "Always On Mode", and "Car Mode". The user can operate the second switch 14 (in this embodiment, a toggle switch) to switch modes. (1) "Off Mode" means the entire machine is not working. (2) "Always On Mode" means the aroma diffuser is always working, and after the spray interval set by the first switch 13, the aroma diffuser will spray for 1 second. (3) "Car Mode" means that after the spray interval set by the first switch 13, when the vibration sensor 21 detects that the car is starting, the aroma diffuser will spray for 1 second. For example, the machine is set to spray at 30 seconds. The machine sprays once at 0 seconds. When the machine detects that the car is vibrating at 20 seconds and that the car is not vibrating at 30 seconds, the machine will also spray at 30 seconds. The same applies to the next time.

[0030] Secondly, in "Off Mode," the setting of the first switch 13 (in this embodiment, a push-button switch) is disabled. In "Always On Mode" and "Car Mode," the user can set the spray interval by briefly pressing the "button switch." For example, there are four settings: 0, 1, 2, and 3. At setting 0, the ultrasonic waves do not work, similar to the effect in "Off Mode." Settings 1, 2, and 3 respectively set the interval of the aromatherapy diffuser's spray. The higher the setting, the longer the interval. The setting can be indicated by the brightness of the LED light.

[0031] When the machine is in "car mode" and the gear is not "0", if no vibration is detected for 3 consecutive minutes, the machine will automatically shut off and the LED light will turn off. Afterward, it will resume spraying once vibration is detected again.

[0032] The negative ion generator 10 does not operate in "Off Mode" or "Level 0". When the machine is in "Always On Mode" or "Car Mode", it will operate for 2 seconds at the midpoint of the interval between "Levels 1, 2, and 3". For example, if the interval for Level 1 is 30 seconds, it will operate for 2 seconds between the 15th and 16th second after spraying.

[0033] When the machine sprays, the essential oil in bottle 4 is guided to the ultrasonic atomizer 2 through the liquid guide rod 3. When the ultrasonic atomizer 2 starts working under the control of the main control circuit board 9, it atomizes the essential oil and sprays it out to create an aromatherapy effect.

[0034] The advantages of this utility model are: 1. This utility model combines a bottle 4 with a liquid guide rod 3 with an upper shell 6 and fixes an ultrasonic atomizer 2 on the top of the upper shell 6. It makes full use of the space in the lower shell 7 to accommodate the lower part of the bottle 4. At the same time, the main control circuit board 9 with a vibration sensor 21 and the negative ion generator 10 are placed in the lower shell 7. The battery 12 is fixed in the space between the upper cover 16 and the upper shell 6, so that the structure of the aroma diffuser is more compact and can be compatible with both home and car applications.

[0035] 2. In this utility model, the upper shell 6 and the lower shell 7 are both fixedly connected to the positioning partition 5, and the other parts inside the aroma diffuser (except for the upper cover 16 and the base 15) are also fixed in the inner cavity of the upper shell 6 and the lower shell 7. The lower shell 7 is detachably fixedly connected to the base 15, which makes it more convenient to replace the outer shell 1.

[0036] 3. This utility model aroma diffuser has the advantages of ingenious design, simple structure, small size and low cost, and can also be applied to a variety of application scenarios.
