[0026] Please see Figure 1 , Figure 2 This application provides a car-mounted aromatherapy humidifier 1, including a water tank 11, a body structure, a humidification module 13, an aromatherapy module 14, and a heating module. The body structure includes a first structural component 121 connected to the water tank 11, a second structural component 122 connected to the first structural component 121, a third structural component 123 connected to the first structural component 121 as a side wall, and a fourth structural component 124 connected to the third structural component 123 as a top cover. The humidification module 13, the heating module, and the aromatherapy module 14 are mounted on the first structural component 121. The humidification module 13 includes an atomizing plate 131 and a liquid absorption component 132 connected to the atomizing plate 131. The heating module includes a heating tube 15, which is directly or indirectly sleeved on the liquid absorption component 132.

[0027] The water tank 11 is used to store the liquid medium for humidification, which is usually water. The connection between the water tank 11 and the first structural member 121 includes, but is not limited to, snap-fit ​​connection, threaded tightening connection, plug-in connection, etc., and this application does not impose specific limitations on this.

[0028] In some embodiments, a seal is provided between the water tank 11 and the first structural member 121 to prevent leakage of the liquid medium in the water tank 11.

[0029] In some embodiments, the first structural member 121 includes a first receiving chamber 1211, the bottom of which extends toward the water tank 11, and a plurality of drainage holes 12111 are provided on the first receiving chamber 1211; the bottom of the first receiving chamber 1211 is a detachable structure, including a detachable connector 12112 connected to the body of the first receiving chamber 1211; the first structural member 121 also includes a second receiving chamber 1212, the bottom of which extends toward the water tank 11, and the second receiving chamber 1212 is used to house the power module 16 and the liquid level detection module 17 from top to bottom; the first structural member 121 also includes a third receiving chamber 1213, the bottom of which extends in the opposite direction to the water tank 11, and the third receiving chamber 1213 is used to fix the aromatherapy module 14.

[0030] See Figure 3 The first structural component 121 includes a first receiving chamber 1211, which is used to place or replace the liquid absorber 132. The bottom of the first receiving chamber 1211 extends towards the water tank 11. Multiple drainage holes 12111 are provided on the first receiving chamber 1211. When the first structural component 121 is connected to the water tank 11, water in the water tank 11 seeps into the first receiving chamber 1211, wetting the liquid absorber 132. The bottom of the first receiving chamber 1211 is a detachable structure, including a detachable bottom connector connected to the bottom of the chamber. The detachable structure and the bottom of the chamber are respectively provided with mating connection structures, including but not limited to snap-fit ​​connections, threaded tightening connections, and plug-in connections. When it is necessary to insert or replace the liquid absorber 132, the detachable connector 12112 is removed from the bottom of the chamber, and the liquid absorber 132 is placed into or removed from the car air freshener humidifier 1.

[0031] In some embodiments, see Figure 4 The detachable connector 12112 is provided with a spring 12113. The lower end of the liquid absorber 132 is in contact with the spring 12113. The compression or extension of the spring 12113 allows the top end of liquid absorbers 132 of different lengths to be connected to the atomizing plate 131.

[0032] In some embodiments, the car air freshener humidifier 1 also includes a temperature detection module (not shown in the figure). The temperature detection module is installed in the water tank 11 and is used to detect the temperature of the water in the water tank 11. When the water temperature is lower than the preset minimum value, it indicates that the water or even the liquid absorption element 132 is frozen. The liquid absorption element 132 cannot effectively absorb water, and the atomizing plate 131 cannot atomize. At this time, the water is restored to a liquid state by controlling the heating tube 15, so that the humidification module 13 can resume normal operation.

[0033] In some embodiments, the heating tube 15 is disposed within the first receiving chamber 1211 and sleeved on the liquid absorption member 132; or, the heating tube 15 is sleeved on the first receiving chamber 1211.

[0034] By directly mounting the heating tube 15 onto the liquid absorber 132 or onto the first receiving chamber 1211, the heat from the heating tube 15 can directly act on the liquid absorber 132 itself, preferentially melting the ice layer inside the liquid absorber 132, avoiding the heat being consumed by the large amount of water in the water chamber 11 first, thereby quickly opening up the water transfer channel and allowing the liquid absorber 132 to quickly restore its "adsorption-water conduction" function.

[0035] The length of the heating tube 15 can be flexibly set, and it can cover the entire liquid absorption element 132 or a part of the liquid absorption element 132. This application does not limit this.

[0036] For specific implementation details, see Figure 12 The heating tube 15 includes an inner tube 151, an outer tube 152, and a heating wire 153 disposed between the inner tube 151 and the outer tube 152. The two ends of the inner tube 151 and the outer tube 152 are sealed with a second sealing waterproof component 154.

[0037] The second sealing and waterproofing component 154 can be formed by welding, such as tin welding.

[0038] In the heating module, except for the heating wire 153, the other parts are made of stainless steel.

[0039] In some embodiments, the distance between the heating tube 15 and the bottom of the water tank 11 is greater than a preset distance. The heating tube 15 needs to be installed at a certain distance from the water tank 11 to prevent the heat generated during heating from damaging the bottom structure of the water tank 11.

[0040] In some embodiments, see Figure 2 , Figure 4The liquid absorber 132 is inserted into the first receiving chamber 1211 of the first structural member 121, and the top end of the liquid absorber 132 extends to the top end of the second structural member 122. An atomizing plate mounting part 1221 is provided at the top end. A first sealing and waterproofing member and the atomizing plate 131 are arranged sequentially from bottom to top in the atomizing plate mounting part. The top end of the liquid absorber 132 is connected to the atomizing plate 131.

[0041] The atomizing methods of the atomizing plate 131 include, but are not limited to, ultrasonic and cold evaporation. Ultrasonic atomization utilizes high-frequency vibration (generally generated by piezoelectric ceramics or other materials under high-frequency voltage) to break down water molecules and atomize them into micron-sized particles. Cold evaporation atomization uses a filter (usually made of highly absorbent materials such as fiber filters) to absorb water, and then uses a fan to accelerate airflow, causing the water to evaporate more quickly under natural conditions, thereby dispersing the water vapor into the air and achieving humidification. The above atomization methods are merely two examples provided in this application and do not impose any limitations on the atomization methods used in this application. Other atomization methods can also be used in this application, and no specific limitations are imposed on them.

[0042] The liquid absorbent 132 can be a cotton swab, and the liquid absorbent 132 can be replaced.

[0043] In some embodiments, the distance between the bottom of the first receiving chamber 1211 and the water tank 11 is less than a certain distance, so that the liquid absorption component 132 can completely absorb the liquid in the water tank 11. On the one hand, this can improve the utilization rate of the liquid in the water tank 11, and on the other hand, avoid the risk of microbial (bacteria, mold, etc.) growth caused by long-term liquid residue in the water tank 11, ensure the hygiene of the liquid medium storage environment, and maintain the functional stability of the equipment and the safety of user use.

[0044] See Figures 3-5 The first structural component 121 also includes a second receiving compartment 1212, which is used to house the power module 16 and the liquid level detection module 17. The bottom of the second receiving compartment 1212 extends towards the water tank 11. The power module 16 and the liquid level detection module 17 are placed sequentially from top to bottom inside the second receiving compartment 1212. The liquid level detection module 17 is located at the bottom and is used to detect the water level in the water tank 11. When the water level in the water tank 11 drops below the height of the liquid level detection module 17, the liquid level detection module 17 confirms that the water level is too low and reminds the user to add water.

[0045] The liquid level detection module 17 adopts existing technologies, including but not limited to capacitive liquid level modules, resistive liquid level modules, and pressure liquid level modules.

[0046] The first structural component 121 also includes a third receiving compartment 1213, which is used to fix the aromatherapy module 14. The bottom of the third receiving compartment 1213 extends in the opposite direction to the water tank 11.

[0047] In some embodiments, the aromatherapy module 14 includes an essential oil component 141 and an air supply component 142. The essential oil component 141 includes an essential oil bottle 1411 containing essential oil, a bottle cap 1412 connected to the essential oil bottle 1411, and an essential oil absorber 1413 passing through the bottle cap 1412. A first connector is provided on the bottle cap 1412, and a second connector and a first opening 12131 are provided on the top of the third receiving chamber 1213. The essential oil component 141 is fixed by the first connector and the second connector. The first structural member 121 is attached to the second structural member 122; the second structural member 122 further includes an air supply channel 1222; the third structural member 123 includes a pair of radially arranged vents, through which airflow can enter from the first vent 1231 and be blown out from the second vent 1232 via the air supply channel 1222; the essential oil absorber 1413 passes through the first opening 12131 and is exposed in the air supply channel 1222; the air supply assembly 142 is disposed on the side of the second structural member 122 where the first vent 1231 is located.

[0048] See Figure 6 The aromatherapy module 14 includes an essential oil component 141, which includes an essential oil bottle 1411 containing essential oil, a bottle cap 1412 connected to the essential oil bottle 1411, and an essential oil absorber 1413 inserted through the bottle cap 1412. The bottle cap 1412 and the essential oil bottle 1411 can be connected by any connection method such as snap-on connection, threaded tightening connection, or plug-in connection. The essential oil absorber 1413 is inserted through the bottle cap 1412, with one end inserted into the essential oil bottle 1411 and the other end exposed to the air, which can achieve stable adsorption and slow evaporation of essential oil from the inside to the outside of the bottle, thus achieving a natural aromatherapy effect.

[0049] The essential oil component 141 is connected to the first structural member 121 via a first connector on the cap 1412 and a second connector on the third receiving compartment 1213. The first and second connectors can be any structural members with a connecting effect, including but not limited to snap-fit ​​connections, threaded connections, and plug-in connections. For example, the first connector is an elastic claw, and the second connector, with a slot and a protrusion at the top of the third receiving compartment 1213, is used. The elastic claw is inserted into the slot, and after rotating at a preset angle, the claw is fixed to the protrusion, thus connecting the essential oil component 141 to the first structural member 121.

[0050] In some embodiments, a third waterproof seal 1414 is provided at the position where the essential oil component 141 is in fixed contact with the first structural member 121 to prevent water in the water tank 11 from entering the body structure.

[0051] The first structural member 121 is also provided with a first opening 12131 for the essential oil absorption member 1413 to pass through.

[0052] Among them, see Figure 5 , Figure 7 The first structural member 121 is connected to the second structural member 122, for example, the second structural member 122 is fixed to the first structural member 121 by fasteners (such as screws). The second structural member 122 is also provided with an air supply channel 1222. The third structural member 123 includes a pair of radially arranged vents, including a first vent 1231 and a second vent 1232. Airflow can enter from the first vent 1231 and be blown out from the second vent 1232 through the air supply channel 1222. The essential oil absorber 1413 passes through the first opening 12131 and is exposed in the air supply channel 1222, where the radially flowing airflow promotes the evaporation of the essential oil.

[0053] Furthermore, to improve the evaporation efficiency of the aromatherapy, the aromatherapy module 14 also includes an air supply component 142, which can be a fan. The air supply component 142 is located on the side of the second structural member 122 where the first vent 1231 is located. The air supply component 142 accelerates the airflow, thereby improving the evaporation efficiency of the essential oil.

[0054] In another embodiment, see Figure 8 The essential oil component 141 includes an aromatherapy bottle 1415 and an atomizing head 1416.

[0055] In this embodiment, the atomizing method of the atomizing head 1416 includes, but is not limited to, ultrasonic and electrothermal methods. Ultrasonic atomization utilizes the high-frequency oscillation characteristics of ultrasound to disperse and atomize the essential oil mixture formed by mixing essential oils with solvents such as water into extremely fine particles. These tiny particles are suspended in the air, thereby achieving aroma diffusion. Electrothermal atomization uses heating elements (such as heating wires, heating plates, etc.) to heat the essential oils, raising their temperature, accelerating the movement of essential oil molecules, and promoting rapid evaporation, thus diffusing the fragrance into the surrounding air. The above atomization methods are merely two examples provided in this application and do not impose any limitations on the atomization methods of this application. This application may also use other methods for atomization, and no specific limitations are imposed on these methods.

[0056] In some embodiments, the aroma diffuser bottle 1415 and the atomizing head 1416 are integrated into one unit; or, the aroma diffuser bottle 1415 and the atomizing head 1416 are separate units.

[0057] The aromatherapy module 14 includes two consumable replacement options: either the aromatherapy bottle 1415 and the atomizing head 1416 can be replaced as a whole, or the aromatherapy bottle 1415 can be replaced individually.

[0058] In some embodiments, the fourth structural member 124 is provided with a second opening 1241, which is correspondingly provided with the atomizing plate 131.

[0059] Among them, see Figure 1 , Figure 5 , Figure 9 The fourth structural component 124 is the top cover of the car-mounted aromatherapy humidifier 1. The fourth structural component 124 is connected to the third structural component 123, and the connection method can be any method such as a snap-fit ​​connection, a threaded tightening connection, or a plug-in connection. The fourth structural component 124 is provided with a second opening 1241, which allows the mist generated by the atomizing plate 131 to pass through and enter the external environment. In this embodiment, the material of the top cover is not limited; the top cover material can be any material.

[0060] In some embodiments, see Figure 10 The car-mounted aromatherapy humidifier 1 also includes a light module 18. The fourth structural component 124 is a transparent cover. The light module 18 includes the fourth structural component 124, a transparent light diffuser plate 181, and a light plate 182. The light plate 182 is disposed on the second structural component 122, and the transparent light diffuser plate 181 is disposed on the light plate 182. A third opening 1811 is provided on the transparent light diffuser plate 181, and the third opening 1811 is correspondingly disposed with the atomizing sheet 131.

[0061] The lighting module 18 is used to provide lighting effects, and can display different lighting effects according to the aromatherapy power, aromatherapy type, humidification power, etc., to improve the user experience.

[0062] The fourth structural component 124 is the top cover of the car-mounted aromatherapy humidifier 1. The top cover is a transparent shell with light transmission (e.g., made of PC (polycarbonate), acrylic, or other materials with high light transmittance and impact resistance). The lighting module 18 includes a transparent shell, a transparent light diffuser plate 181, and a light plate 182. The light plate 182 includes multiple LED beads 1821. The light plate 182 is mounted on the second structural component 122, the transparent light diffuser plate 181 is mounted on the light plate 182, and the transparent shell is connected to the third structural component 123.

[0063] The fourth structural component 124 is provided with a second opening 1241, and the light transparent diffuser plate 181 is provided with a third opening 1811. The second opening 1241 and the third opening 1811 are provided in correspondence with the atomizing plate 131, so that the mist generated by the atomizing plate 131 can pass through the second opening 1241 and the third opening 1811 and diffuse into the external environment space.

[0064] In order to prevent fog from entering the body structure, the second opening 1241 and the third opening 1811 are both located at the position of the atomizing plate 131 and are fixed to the atomizing plate mounting part 1221 at the opening end of the light transparent diffuser plate 181.

[0065] The light-transparent diffuser plate 181 also has a shielding plate 1812 on its open end, which is used to decorate the connection surface between the light-transparent diffuser plate 181 and the atomizing plate mounting part 1221.

[0066] In some embodiments, see Figure 10 The in-vehicle aromatherapy humidifier 1 also includes an interactive module 19, which includes a display panel 191 and a backlight assembly 192. The backlight assembly 192 includes a light guide plate and LED beads. The display panel 191 is disposed on the third structural member 123, and the backlight assembly 192 is disposed on the second structural member 122. The display panel 191 and the backlight assembly 192 are correspondingly disposed.

[0067] The display panel 191 is disposed on the third structural member 123, and may be all or part of the third structural member 123.

[0068] The display panel 191 includes, but is not limited to, a display screen, a digital tube, indicator lights, etc. The display screen can be a touch screen or a non-touch screen.

[0069] In addition, the interaction module 19 may also include operation components, including but not limited to physical buttons and touch buttons. When the operation component is a touch button, the core function of the touch button is to generate an electrical signal (capacitance change or pressure signal) through user touch (such as finger pressing), and transmit the signal to the control chip of the circuit board to realize function triggering.

[0070] For example, see Figure 11 The interactive module 19 includes an operation component and a display component. The display component includes a display panel 191, and the operation component includes operation controls 193. The operation controls 193 are capacitive controls, such as... Figure 11 The device includes an aromatherapy function key 1931, a power on / off key 1932, and a humidification function key 1933.

[0071] The various functions can be activated or deactivated by triggering each capacitor control. For example, a long press of the power button 1932 turns the car air freshener humidifier 1 on or off, while a single click of the power button 1932 switches the lighting mode. A long press of the air freshener function button 1931 turns the air freshener function on or off, while a single click of the air freshener function button 1931 switches the fragrance concentration, which is displayed on the display panel 191. A long press of the humidification function button 1933 turns the humidification function on or off, while a single click of the humidification function button 1933 switches the humidity target, which is displayed on the display panel 191.

[0072] The display panel 191 is also used to display whether each module is installed correctly and its on / off status. For example, if the aromatherapy function is not activated, the display panel 191 will not display anything; when the aromatherapy function is activated, an aromatherapy icon will be displayed; if the aromatherapy module is not installed correctly, the aromatherapy icon will flash red. The display panel 191 is also used to display Bluetooth connection status, current humidity, battery level, and other information.

[0073] The above-mentioned interactive content is only a few examples provided in this application. The specific interactive situation can be set according to actual needs, and this application does not impose any restrictions on it.

[0074] In some embodiments, the third structural member 123 further includes a charging port.

[0075] In some embodiments, each module in the liquid level detection module 17 and the temperature detection module is an independently configured module; or, the liquid level detection module 17 and the temperature detection module are integrated into a single module.

[0076] The car-mounted aromatherapy humidifier 1 also includes a liquid level detection module 17 and a temperature detection module. These modules are located on one side of the water tank 11. The liquid level detection module detects the liquid level in the water tank 11, while the temperature detection module detects the liquid temperature or the internal temperature of the water tank 11 excluding the liquid. These modules can be integrated or installed independently. When designed independently, each module can be distributed according to the overall structure of the device (such as cavity layout, heat dissipation requirements, and installation space). If a single module fails, only that module needs to be replaced or repaired, without disassembling other functional units, reducing maintenance complexity and cost. When multiple modules are integrated, redundant space between modules is significantly reduced, lowering material and processing costs and meeting miniaturization design requirements. In actual design, these modules can be flexibly configured as needed.

[0089] Please see Figure 14 , Figure 14 A schematic flowchart illustrating a heating method for a car-mounted aromatherapy humidifier provided in this application embodiment is shown below. Figure 14 As shown, the method is applied to, for example Figure 1 The car-mounted aromatherapy humidifier 1 shown is specifically applied to the main control chip of the car-mounted aromatherapy humidifier 1. The method includes the following steps S1401-S1404: Step S1401: Receive the reference temperature from the temperature detection module.

[0090] The reference temperature is either the water temperature in the water tank of the car air freshener or the air temperature in the internal space of the water tank excluding the water.

[0091] Step S1402: The reference temperature is detected to be lower than the preset minimum temperature.

[0092] Step S1403: Send a heating command to the heating module.

[0093] The heating command is used to instruct the heating module to perform a heating operation.

[0094] Step S1404: Periodically acquire reference temperatures from the temperature detection model group until the reference temperature is detected to be greater than the preset minimum temperature, then stop the heating operation.

[0095] Specifically, when the reference temperature in the water tank is less than or equal to the preset minimum temperature, it indicates that the liquid in the water tank is frozen. In this case, the heating module is automatically triggered to heat the water. During the heating process, the reference temperature in the water tank is constantly monitored. When the reference temperature is detected to be greater than the preset minimum temperature, the heating module is controlled to stop heating.

[0096] As can be seen from the embodiments of this application, the control logic that triggers the heating module to heat by setting a temperature threshold can achieve precise intervention and dynamic management of the frozen state of the liquid in the water tank, ensuring that the liquid in the water tank is in a non-frozen state, guaranteeing that the humidifying module can normally extract or atomize the liquid, avoiding equipment downtime due to freezing, and ensuring the availability of equipment functions. At the same time, it can also avoid the risk of deformation of components such as water tank and pipelines due to volume expansion after the liquid freezes, reducing energy consumption and safety risks. In addition, the heating control logic responds automatically throughout the entire process, completing the closed-loop control of "freeze detection - heating start - shutdown after ice melting" without manual intervention, realizing automated intelligent operation and maintenance.
