[0024] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0025] like Figures 1 to 7 As shown, this utility model discloses an electric fragrance diffuser capable of detecting the remaining amount of fragrance liquid, including a bottle body 1 and a core rod 2 with one end inserted into the bottle body 1. The upper part of the bottle body 1 is provided with a shell 3 that can cover the core rod 2. The shell 3 is provided with an exhaust port 31. The core rod 2 is connected to a heating element 4 that can heat the core rod 2. The fragrance diffuser also includes a detection device 5 that can detect changes in at least one of the parameters of voltage, current, resistance, temperature, and humidity of the core rod 2 or changes in at least one of the parameters of temperature and humidity around the core rod 2.

[0026] Bottle 1 is used to store fragrance liquid. The core rod 2 guides the fragrance liquid in bottle 1. The core rod 2 is heated by heating element 4 to promote the evaporation of the fragrance liquid in the core rod 2, and the evaporated fragrance liquid is released to the outside through exhaust port 31. Detection device 5 monitors changes in various parameters of the core rod 2 or its surrounding environment to determine the remaining amount of fragrance liquid.

[0027] In one embodiment, when there is fragrance liquid in the bottle 1, the core rod 2 becomes wet, the impedance of the core rod 2 is low, the current is large, and the voltage is high. Conversely, when there is no fragrance liquid in the bottle, the core rod 2 becomes dry, the impedance increases, the current decreases, and the voltage decreases. The detection device 5 detects the changes in the voltage, current, and resistance parameters of the core rod 2 and feeds them back to the computing chip. The computing chip processes the parameter changes fed back by the detection device 5 through an algorithm to identify the data change of the core rod 2 from a wet state to a dry state, thereby identifying the liquid level change in the bottle and realizing the detection of the remaining fragrance liquid in the bottle 1.

[0028] In one embodiment, when there is fragrance liquid in the bottle 1, the core rod 2 is moist. Due to the evaporative cooling effect of the liquid, the temperature of the core rod 2 or its surroundings is relatively low. Conversely, when there is no fragrance liquid in the bottle 1, the core rod 2 becomes dry, and the temperature is relatively high. When there is fragrance liquid in the bottle 1, the core rod 2 is moist, and the humidity of the core rod 2 or its surroundings is relatively high. Conversely, when there is no fragrance liquid in the bottle 1, the core rod 2 becomes dry, and the humidity is relatively low. The detection device 5 detects the changes in temperature and humidity parameters of the core rod 2 or its surroundings and feeds them back to the computing chip. The computing chip processes the parameter changes fed back by the detection device 5 through an algorithm to identify the data change of the core rod 2 from a moist state to a dry state, thereby identifying the liquid level change in the bottle and realizing the detection of the remaining fragrance liquid in the bottle 1.

[0029] By setting up a detection device 5 that can detect changes in at least one of the parameters of the mandrel voltage, current, resistance, temperature, and humidity, or changes in at least one of the parameters of temperature and humidity around the mandrel, the remaining amount of fragrance liquid can be monitored relatively accurately even if different users have different usage habits, thus improving the user experience.

[0030] The upper part of the bottle body 1 is connected to the mounting base 6, and the detection device 5 is mounted on the mounting base 6.

[0031] The mounting base 6 provides a stable mounting platform for the detection device 5. At the same time, the mounting base 6 on the upper part of the bottle body 1 allows the detection device 5 to be closer to the core rod 2 and its surrounding environment, thereby more accurately detecting the required changes in electrical or thermal parameters.

[0032] The detection device 5 includes a probe 51 that can be inserted into the upper part of the core rod 2.

[0033] like Figure 2 , 3 As shown in Embodiment 1, probe 51 is inserted into the upper part of core rod 2 and can directly contact core rod 2. Since it is a direct contact measurement, probe 51 can provide instant feedback, thereby more accurately measuring changes in parameters such as voltage, current, and resistance.

[0034] The mounting base 6 includes a base 61, the base 61 is provided with an upwardly extending support portion 62, the upper part of the support portion 62 is connected to an end frame 63, and the probe 51 is disposed on the end frame 63.

[0035] The base 61 is fixed to the upper part of the bottle body 1 to ensure the stability of the entire structure. The support part 62 extends upward from the base 61 and connects the base 61 and the end frame 63. Located at the top of the support part 62, it is used to support and fix the probe 51. The modular structure composed of the base 61, the support part 62 and the end frame 63 allows each part to be designed and manufactured independently, reducing production and maintenance costs.

[0036] The detection device 5 includes a contact piece 52 that abuts against the side wall of the core rod 2.

[0037] like Figure 4 , 5 As shown in Embodiment 2, the contact piece 52 has a certain elasticity, thus maintaining stability during electrical contact with the side wall of the mandrel 2. A contact piece 52 is provided on each side of the mandrel 2, forming double-sided contact, improving measurement accuracy and stability, and more accurately capturing changes in the state of the mandrel 2.

[0038] The mounting base 6 includes a base 61, the base 61 is provided with an upwardly extending support part 62, the support part 62 is connected to a mounting platform 64, the mounting platform 64 has a mounting port 641 for the core rod 2 to pass through, and the contact piece 52 is provided on the mounting platform 64.

[0039] In Embodiment 2, the contact piece 52 has a pressing part, which is located between the side wall of the mounting port 641 and the side wall of the core rod 2, thereby ensuring that the contact piece 52 and the core rod 2 maintain close contact.

[0040] In Embodiment 2, the mounting platform 64 is provided with a fixing protrusion that extends into the mounting port 641 to press against the core rod 2, ensuring that the core rod 2 is accurately fixed in its predetermined position when passing through the mounting port 641, preventing it from shifting or shaking.

[0041] The heating element 4 is mounted on the mounting base 6.

[0042] By mounting the heating element 4 on the mounting base 6, the need for additional connecting wires and brackets is reduced, making the overall design more compact. The mounting base 6 also makes it easier to assemble the heating element 4 with components such as the detection device 5, reducing production and maintenance costs.

[0043] The housing 3 is provided with a receiving cavity 32, one end of the core rod 2 extends into the receiving cavity 32, and the detection device 5 includes a sensor 53 located in the receiving cavity 32 and capable of detecting temperature and / or humidity.

[0044] like Figure 6 , 7 As shown in Embodiment 3, the receiving cavity 32 provides physical protection for the core rod 2 and sensor 53, preventing external dust, moisture, or other contaminants from entering and ensuring a clean working environment for the internal components. Sensor 53 can directly measure temperature changes within the receiving cavity 32, indirectly reflecting the presence and remaining amount of fragrance liquid through changes in heat transferred by the core rod 2. Sensor 53 can also monitor the humidity level within the receiving cavity 32, using humidity changes caused by fragrance liquid evaporation to determine the state of the fragrance liquid.

[0045] In Embodiment 3, a mounting plate is provided inside the receiving cavity 32. The two ends of the mounting plate are connected to the inner wall of the housing 3. The mounting plate has a downward-facing mounting groove, and the sensor 53 is disposed in the mounting groove. The connection between the two ends of the mounting plate and the inner wall of the housing 3 ensures its stable position within the receiving cavity 32 and prevents the sensor 53 from shifting due to vibration or movement.

[0046] The exhaust port 31 is located on the top surface of the housing 3, and the sensor 53 is located between the exhaust port 31 and the end of the core rod 2 near the exhaust port 31.

[0047] The exhaust port 31 is located on the top surface of the housing 3, which facilitates the diffusion of fragrance gas into the environment and provides a better fragrance diffusion effect. The sensor 53 is located between the exhaust port 31 and the end of the core rod 2 near the exhaust port 31, which can directly detect the temperature and humidity changes caused by the fragrance liquid volatilized from the core rod 2, thereby improving the accuracy of the data.

[0048] The fragrance diffuser also includes a control circuit board 7, and the detection device 5 is electrically connected to the control circuit board 7.

[0049] The control circuit board 7 can centrally manage and coordinate the operation of various components such as heating element 4, detection device 5, and sensor 53. Through the built-in microprocessor or computing chip, the control circuit board 7 can execute complex algorithms based on the data fed back by the detection device 5 to achieve accurate monitoring of the remaining amount of fragrance liquid.
