Description

Technical Field

[0001] This utility model relates to the field of vehicle electronics, and in particular to a vehicle aromatherapy device. Background Technology

[0002] Currently, some in-car air fresheners on the market are devices that provide in-car air freshening functions on their own, while others are integrated devices that combine in-car charging and in-car air freshening functions. These types of in-car air fresheners are usually connected to the vehicle's internal power supply interface (such as the cigarette lighter interface) to draw power and thus achieve the in-car air freshening function, or achieve both in-car air freshening and in-car charging functions.

[0003] However, existing integrated devices that combine in-vehicle charging and in-vehicle aromatherapy functions typically install the aromatherapy component inside the main body of the in-vehicle aromatherapy device. While this structure reduces the size of the main body, it makes it difficult to install and replace the aromatherapy component, making it difficult to easily change the aromatherapy. Furthermore, because the aromatherapy component is installed inside the main body's internal cavity, there is spatial interference between the aromatherapy component and the charging component, which increases the design and manufacturing difficulty. Without significantly increasing the size of the main body, it is impossible to achieve the retractable storage of the charging cable.

[0004] Therefore, how to reduce the difficulty of installing and replacing aromatherapy components while enabling aromatherapy components and charging components to effectively share the same vehicle power interface, and how to achieve retractable charging cable storage while effectively reducing the size of the vehicle aromatherapy device itself, has become a technical problem that urgently needs to be solved.

[0005] In view of the above, this application is hereby submitted. Utility Model Content

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0026] This utility model discloses a car air freshener, which aims to solve the problem that the fixed fragrance diffusion amount of existing car air fresheners cannot meet the needs of different users.

[0027] Please see Figures 1 to 2 This utility model provides a car air freshener device, including: a base 8, a receiving cavity formed inside the base 8, a retractable charging cable assembly 4 disposed inside the receiving cavity, an air freshener assembly disposed above the retractable charging cable assembly 4, and a power supply connector assembly 7 disposed below the base 8.

[0028] The lower part of the receiving cavity has a lower opening, and the power connector assembly 7 is mounted on the base 8 through the lower opening. The power connector assembly 7 is used to connect to the vehicle power interface.

[0029] The receiving cavity has a first side opening 81, and the charging cable of the retractable charging cable assembly 4 can pass through the first side opening 81 and extend or retract.

[0030] The aromatherapy component includes a control panel 3, an atomizing component 6 disposed on the control panel, and an oil reservoir 61 detachably disposed on the atomizing component 6, wherein a base 2 formed on the control panel 3 is used to install the oil reservoir 61.

[0031] The control panel 3 is equipped with a touch switch 32, which is configured to adjust the airflow of the aromatherapy component based on the duration of the user's touch.

[0032] It should be noted that the power connector assembly 7 is located below the base 8, and its function is to connect to the vehicle's power interface to obtain power. Specifically, this assembly is a standard cigarette lighter plug that can be inserted into the vehicle's cigarette lighter socket to draw power from the vehicle's battery. The plug has an internal fuse for protection against overcurrent damage to the device or the vehicle. The power connector assembly 7 transmits power to the controller and aromatherapy component through internal circuitry (e.g., a voltage regulating circuit converts DC24V to 3.3V for use by the controller 1), providing stable power support for the operation of the entire device.

[0033] In one possible implementation of this utility model, the control panel 3 integrates a controller, the input terminal of the controller is electrically connected to the touch switch 32, and the output terminal of the controller is electrically connected to the control terminal of the atomizing component 6.

[0034] The controller can be an STM32 series microcontroller. The touch switch 32, mounted on the surface of the base 8, is the main interface for user interaction with the car air freshener. It uses a capacitive touch sensor design and supports short and long press operations. The touch switch 32 is configured to adjust the airflow of the air freshener component based on the duration of the user's touch. Specifically, when the user short-presses the touch switch 32 (touch time less than 1 second), the air freshener component turns on or off; and when on, the airflow is at the first level. When the user long-presses the touch switch 32 (touch time more than 2 seconds), the airflow is at the second level.

[0035] In the actual workflow, the user first inserts the power connector assembly 7 into the car's cigarette lighter socket, and the device is ready to use after being powered on. The user activates the aromatherapy unit by briefly pressing the touch switch 32. At this time, the atomizer starts working, the fan 63 runs at the default speed, and the fragrance diffuses into the car from the air outlet. If the fragrance concentration needs to be adjusted, the user presses and holds the touch switch 32. After the controller detects the continuous touch signal, it gradually increases the speed of the fan 63 to increase the air volume; pressing the touch switch 32 again briefly turns off the aromatherapy unit.

[0036] In one possible implementation of this utility model, a digital display tube 31 is further disposed on the surface of the control panel 3, and the input terminal of the digital display tube 31 is electrically connected to the input terminal of the controller; wherein, the digital display tube 31 is used to display the current working level of the atomizing component 6 and / or the current power supply voltage (for example, it can display the car battery voltage, 7.6-29V, the voltage of a small car battery is generally around 12V, and the voltage of a large car battery is generally around 23V).

[0037] When the user adjusts the airflow or aroma release intensity of the aroma diffuser component via touch switch 32, the controller receives the corresponding signal, adjusts the operating status of the aroma diffuser component, and transmits the current operating level to the display digital tube 31. For example, the aroma diffuser component 6 may have three operating modes: low, medium, and high. The display digital tube 31 will display "1", "2", and "3" respectively to correspond to these levels, ensuring that the user can clearly understand the operation of the device. Of course, in one possible implementation of this utility model, it can also display the current output voltage.

[0038] In one possible implementation of this utility model, the retractable charging cable assembly 4 includes a limiting member 42, a spring-back mechanism 41, and a charging cable disposed on the spring-back mechanism 41;

[0039] The spring mechanism 41 is fixed in the receiving cavity by the limiting member 42, the first end of the retractable charging cable is electrically connected to the output end of the power take-up connector assembly 7, and the second end of the retractable charging cable passes through the receiving cavity and is equipped with a charging connector.

[0040] The charging connector can be pulled out from the side of the base 8 and used to connect to the charging interface of an electronic device.

[0041] It should be noted that the retractable charging cable adopts a coiled design. The cable is stored inside the base 8 via a small spool with a built-in spring mechanism. When the user pulls out the charging cable, the spring is stretched, and the cable automatically retracts upon release, ensuring the neat appearance of the base 8. The first end of the charging cable is fixed to the center of the spool and connected to the output end of the power connector assembly 7 via internal wires. The second end of the charging connector uses a universal interface, such as Type-C, compatible with most electronic devices on the market. In use, the user simply pulls the charging connector on the side of the base 8 to extend the cable to the desired length and connect it to the charging port of a mobile phone, tablet, or other device. Power is transmitted to the electronic device through the retractable charging cable 4 from the power connector assembly 7. After use, the user can gently pull the charging connector, and the cable automatically retracts into the base 8. The operation is simple and does not take up extra space, avoiding clutter inside the vehicle.

[0042] In one possible implementation of this utility model, the atomizing component 6 includes a fan 63 disposed below the control panel 3 and an atomizing unit 62 disposed below the oil reservoir 61;

[0043] The control terminal of the atomizing unit 62 and the control terminal of the fan 63 are electrically connected to the controller. The power supply terminal of the atomizing component 6 and the power supply terminal of the fan 63 are electrically connected to the output terminal of the power connector component 7. The fan 63 can blow the atomizing unit 62 into the vehicle.

[0044] See Figure 2 The exploded view shown is a structural embodiment. The upper shell assembly of the atomizing component 6 (not labeled in the figure) is shown above the oil storage tank 61. The structure of the upper shell assembly of the atomizing component 6 is not unique. The contribution of this utility model to the prior art is not in this respect. The structure of the upper shell assembly can be any applicable upper shell structure, which will not be described in detail here.

[0045] See Figure 2 The exploded view shown is a structural embodiment. The position between the atomizing unit 62 and the components of the control panel 3 is an encryption component (not labeled in the figure). The encryption component is used to connect to the power connector assembly 7 based on an encryption algorithm. Using the encryption component to obtain power from the car charger is a common technical means in the field, which will not be described in detail here.

[0046] It should be noted that the oil reservoir 61 can be made of transparent material, allowing users to easily observe the remaining aromatherapy oil level. It is a detachable structure for convenient replacement or replenishment of the aromatherapy oil, with an internal capacity of approximately [number] milliliters, sufficient for extended use. The atomizing component 6 is tightly connected below the oil reservoir 61, and the aromatherapy oil flows smoothly into the atomizing component 6 through gravity or capillary action. The atomizing component 6 utilizes ultrasonic atomization technology, with a built-in high-frequency oscillator that transforms the aromatherapy oil into micron-sized mist particles through vibration. This preserves the purity of the aroma while facilitating rapid diffusion. Its control terminal is electrically connected to the controller, which adjusts the atomizer's operating frequency according to user commands to control the atomization intensity. The power supply terminal is electrically connected to the output terminal of the power connector assembly 7, obtaining stable power from the vehicle's power supply. Below the atomizing component 6 is a small DC fan 63 with adjustable speed, used to blow the atomized aroma particles from the air outlet into the car. Its control terminal is also electrically connected to the controller, which controls the air volume by adjusting the speed of the fan 63 (for example, the speed of the fan 63 can be controlled by a PWM signal). The power supply terminal is electrically connected to the output terminal of the power connector component 7 to ensure continuous operation.

[0047] In one possible implementation of the invention, a charging interface assembly is further included: a charging interface assembly disposed on the control panel 3, wherein the charging interface assembly is adapted to a second side opening 83 formed on the base 8, and the charging interface assembly is electrically connected to the output end of the power connector assembly 7.

[0048] The charging interface component includes a USB interface and a Type-C interface.

[0049] It should be noted that the USB port in the charging interface assembly uses the standard USB-A type, which supports a charging specification of 5V / 2.4A and is suitable for most traditional devices, such as smartphones, tablets, or other accessories that use USB charging cables. The adjacent Type-C port supports higher-speed charging protocols, such as USB Power Delivery (PD), which can provide charging power of up to 20V / 3A for modern devices to meet fast charging needs.

[0050] The in-vehicle aromatherapy device provided by this utility model comprises a receiving cavity formed inside the base, a retractable charging cable assembly disposed inside the receiving cavity, an aromatherapy component disposed above the retractable charging cable assembly, and a power supply connector assembly disposed below the base. Through the cooperation of the installation structure and the power supply structure, the difficulty of installing and replacing the aromatherapy component is reduced, while the aromatherapy component and the charging component effectively share the same in-vehicle power supply interface. Furthermore, the charging cable can be retracted and stored while effectively reducing the overall size of the in-vehicle aromatherapy device.
