Description

Technical Field

[0001] This utility model relates to the field of atomizing equipment technology, and in particular to an atomizing device and its oil supply device. Background Technology

[0002] The basic structure of an atomizing device typically includes an oil reservoir, an atomizer, and a power control circuit. To improve continuous oil supply during use, some atomizing devices employ a dual oil reservoir structure, where the first oil reservoir serves as the main oil reservoir unit, and the second oil reservoir acts as the direct oil source for the atomizer coil. In traditional devices, oil transfer between the two relies primarily on gravity, capillary action, or simple mechanical valve control, lacking intelligent management. This makes them prone to oil leaks, seepage, and even atomization abnormalities in special conditions such as when the device is tilted or inverted. Utility Model Content

[0033] Example 1

[0034] This embodiment provides an oil supply device for an atomizing equipment, such as... Figure 1 As shown, it includes:

[0035] First oil storage tank 101 and second oil storage tank 102;

[0036] Solenoid valve 103 is installed in the oil line between the first oil storage tank 101 and the second oil storage tank 102, and is used to control the flow of oil from the first oil storage tank 101 to the second oil storage tank 102.

[0037] Button module 104 is used to output oil filling commands according to user operations;

[0038] Power module 105 outputs power supply voltage at its output terminal;

[0039] The status detection module 106 receives power voltage at its power input terminal and is used to detect the status of the atomizing device.

[0040] The solenoid valve power supply module 107 has a power input terminal that receives power supply voltage and an output terminal that is connected to the solenoid valve. It is used to adjust the power supply voltage to the working voltage that drives the solenoid valve.

[0041] The control module 108 is connected to the output terminal of the power module 105, the output terminal of the button module 104, and the control terminal of the solenoid valve power supply module 107. It is used to control the solenoid valve power supply module 107 to open or close the solenoid valve according to the oil filling command and the status of the atomizing device, so as to make the first oil storage tank 101 fill oil into the second oil storage tank 102 or stop oil filling.

[0042] The first oil storage tank 101 is used for long-term storage of oil or atomizing fluid, while the second oil storage tank 102 is a temporary oil supply tank that directly supplies oil to the atomizing core. The first oil storage tank 101 has a larger volume and can be made of plastic or metal, with a sealed design. The second oil storage tank 102 is located near the atomizing core, has a smaller volume, and has an oil inlet at the bottom that connects to the outlet of the solenoid valve 103. The two are connected by a pipe, in which the solenoid valve is embedded. The solenoid valve 103 acts as an electronic switch element, controlling whether oil flows from the first oil storage tank 101 into the second oil storage tank 102. The solenoid valve 103 can be a normally closed solenoid valve with a rated operating voltage of 12V, a starting current of approximately 2A, and a holding current of approximately 0.3A. The solenoid valve 103 includes a coil, armature, spring, and valve core, and the control signal is provided by the solenoid valve power supply module 107. The button module 104 receives user input (such as pressing) and sends an oil filling command to the control module 108. The button module 104 can be a tactile button, a capacitive touch element, or a touch-sensitive electrode. The button module 104 is connected to the input terminal of the control module 108, and its signal output is high or low level. The power module 105 provides power to the entire oil supply device. The power module 105 may include a battery pack (such as a 3.7V lithium battery) or an external power interface (such as USB). The status detection module 106 detects the spatial attitude or working status of the atomizing device to determine whether oil filling is permitted. The status detection module 106 can be a three-axis G-sensor (accelerometer / angle sensor), connected via I... 2 The solenoid valve communicates with the control module 108 via C or SPI to detect inverted, tilted, or swaying states. The solenoid valve power supply module 107 converts the raw voltage provided by the power supply module 105 into the operating voltage required by the solenoid valve 103; the solenoid valve power supply module 107 can be a Boost-type DC-DC boost / buck circuit; the control terminal connects to the control module 108 to achieve on / off control. The control module 108, as the core control unit, coordinates button commands and status information to control the operation of the solenoid valve power supply module 107; the control module 108 is typically a microcontroller, including multiple GPIO interfaces and I / O pins. 2 C communication port, ADC, level control output port, etc.

[0043] The working process of this embodiment is as follows:

[0044] 1. Initialization phase: After the atomizing device is powered on, the control module 108 reads the information from the status detection module 106, determines the current spatial posture of the device (such as whether it is upside down or tilted), and initializes each functional module.

[0045] 2. Receiving oil filling command stage: When the user presses the button module 104, the button module 104 outputs a high-level signal to the control module 108, triggering the oil filling request.

[0046] 3. Status detection stage: After receiving the oil injection command, the control module 108 first reads the information from the status detection module 106 to determine whether the equipment is in a state that allows oil injection (such as an upright state); if the detection is that the equipment is in an inverted state, the oil injection request is ignored to prevent oil backflow.

[0047] 4. Solenoid valve opening stage: If oil filling is allowed, the control module 108 outputs a control signal to the solenoid valve power supply module 107, activates the solenoid valve power supply module 107, and converts the voltage of the power supply module 105 to a suitable voltage and provides it to the solenoid valve 103.

[0048] 5. Oil filling stage: After the solenoid valve 103 is opened, the oil in the first oil storage tank 101 flows into the second oil storage tank 102 through the valve under the action of gravity, and the oil is automatically filled.

[0049] 6. End stage: After the control module 108 sets the oil injection time or receives the user's key input again, it shuts off the solenoid valve power supply module 107, cuts off the power supply to the solenoid valve 103, and stops oil injection.

[0050] 7. Standby phase: The control module 108 resumes the listening state and waits for the next user operation.

[0051] The technical advantages of the solution provided in this embodiment are as follows: This solution can intelligently control the opening or closing of the solenoid valve according to the user's oil filling command and the current spatial state of the atomizing device, so as to achieve safe and accurate oil filling from the first oil storage tank to the second oil storage tank; by setting up a solenoid valve and its dedicated power supply module, the traditional oil filling method that relies on gravity or mechanical valves is replaced, which improves the controllability and response speed of the oil filling process; at the same time, combined with the status detection module, oil filling is automatically prohibited when the atomizing device is in an abnormal posture such as inverted, which effectively prevents problems such as oil leakage and seepage, and enhances the safety and intelligence of the atomizing device.

[0052] In one implementation, when the atomizing device is in a normal upright position, the first oil storage tank 101 is located above the second oil storage tank 102.

[0053] The first oil storage tank 101 is fixedly installed in the upper part of the device and is used to store a relatively large amount of atomizing liquid, such as 18 mL. The second oil storage tank 102 is located below the first oil storage tank 101, close to the atomizing core assembly, and has a smaller capacity, such as 2 mL, for temporary oil supply. The first oil storage tank 101 and the second oil storage tank 102 are connected by an oil circuit, which is equipped with a solenoid valve 103. The solenoid valve 103 can be opened or closed under the control of the control module 108 to control the flow of oil from the first oil storage tank 101 to the second oil storage tank 102. When the atomizing device is in a normal upright position, the first oil storage tank 101 is above the second oil storage tank 102, and the oil can flow naturally to the second oil storage tank 102 by gravity when the solenoid valve 103 is open, thereby realizing the oil filling operation. When the equipment is in an inverted or tilted state, the control module 108, in conjunction with the position information of the status detection module 106, can automatically prevent the solenoid valve 103 from opening, thus avoiding oil leakage caused by abnormal oil flow.

[0054] The technical advantage of this embodiment is that, through the above structure and working method, the oil injection process is automated, and the safety of the equipment under abnormal use conditions is improved.

[0055] In one implementation, when the control module 108 detects that the atomizing device is in a non-inverted state, it controls the solenoid valve power supply module 107 to open or close the solenoid valve 103 according to the oil filling command. When the control module 108 detects that the atomizing device is in an inverted state, it controls the solenoid valve power supply module 107 to close the solenoid valve 103.

[0056] The control module 108 intelligently controls the start and stop of the solenoid valve power supply module 107 based on user operation and device posture information. The status detection module 106 is a three-axis accelerometer used to detect the spatial posture of the atomizing device in real time. When the user presses the oil filling button module 104, the button signal is transmitted to the control module 108. The control module 108 first calls the status detection module 106 to read the current posture data of the device. If it is determined that the device is not inverted, such as normally upright or tilted at a small angle (e.g., within ±60°), the control module 108 sends an opening signal to the solenoid valve power supply module 107. The solenoid valve power supply module 107 is activated and outputs the required working voltage to the solenoid valve 103, driving the solenoid valve 103 to open and complete the oil filling process from the first oil tank 101 to the second oil tank 102. If the device is determined to be in an inverted state (e.g., the device is rotated more than 120°), the control module 108 will prevent the solenoid valve power supply module 107 from being powered on, ensuring that the solenoid valve 103 remains closed. Even if the user issues an oil filling command, the oil filling operation will not be executed, thereby effectively preventing the oil from being accidentally injected and flowing out in an inverted state and avoiding the risk of oil leakage.

[0057] The technical advantages of this embodiment are as follows: When the control module 108 detects that the atomizing device is in a non-inverted state, it only controls the solenoid valve power supply module 107 to open or close the solenoid valve 103 when it receives an oil filling command, thereby achieving safe oil filling in the normal posture; while when the device is in an inverted state, even if the user operates it by mistake, the control module 108 will forcibly control the solenoid valve power supply module 107 to close the solenoid valve 103, prohibiting the oil filling operation, effectively preventing problems such as oil backflow and leakage caused by the device being inverted, and improving the safety and intelligence of the atomizing device in various usage postures.

[0058] In one implementation, the solenoid valve power supply module 107 boosts the power supply voltage and then outputs the operating voltage to the solenoid valve.

[0059] When the power supply voltage of the atomizing device (such as 3.7V to 4.2V output from a lithium battery) is insufficient to directly drive the solenoid valve 103, the solenoid valve power supply module 107 boosts this voltage, converting it into an operating voltage (such as 12V) capable of driving the solenoid valve 103. The boosted and stable voltage is then output to the solenoid valve 103, enabling it to open normally or maintain its operating state. This boost function is typically implemented by a DC-DC boost circuit, ensuring reliable operation of the solenoid valve 103 while also improving energy efficiency and control accuracy.

[0060] As one implementation method, such as Figure 2 As shown, the solenoid valve power supply module 107 includes a power management chip 204, a switching module 201, a first filter module 202, a boost module 203, a second filter module 206, and a feedback module 205. One end of the switching module 201 is the power input terminal of the solenoid valve power supply module 107. The other end of the switching module 201 is connected to one end of the first filter module 202, the first end of the boost module 203, and the first signal sampling terminal of the power management chip 204. The control terminal of the switching module 201 is the control terminal of the solenoid valve power supply module 107. The other end of the first filter module 202 is grounded. The second end of the boost module 203 is connected to the second signal sampling terminal of the power management chip 204. The third end of the boost module 203 is connected to the first end of the feedback module 205 and one end of the second filter module 206, forming the output terminal of the solenoid valve power supply module 107. The other end of the second filter module 206 is grounded. The third signal sampling terminal of the power management chip 204 is connected to the second end of the feedback module 205, and the third end of the feedback module 205 is grounded.

[0061] The power management chip 204, as the core component of the entire boost control system, collects key potential and load information, adjusts the boost switching frequency and duty cycle, and achieves closed-loop stable control of the output voltage. The power management chip 204 can be a commonly used Boost control IC, integrating functions such as a voltage reference source, error amplifier, PWM modulator, and overvoltage protection. The switching module 201, under the command of the control module 108, controls whether the boost module 203 starts operating. The switching module 201 can be one or more N-channel or P-channel MOSFETs; its gate is controlled by the output signal of the control module 108, its drain is connected to the input power supply, and its source is connected to the filter and boost module 203. The first filter module 202 filters the input voltage, reducing power supply ripple interference and improving boost stability. The first filter module 202 can be a parallel filter network composed of one or more electrolytic capacitors or ceramic capacitors. The boost module 203 raises the low-voltage power supply to the high voltage (e.g., 12V) required for the solenoid valve to operate. The boost module 203 can include inductors, current-controlled MOSFETs, freewheeling diodes, etc. The second filtering module 206 filters the output voltage of the boost module 203 to suppress high-frequency ripple and noise, ensuring stable power supply to the solenoid valve; the second filtering module 206 can be one or more large-capacity capacitors. The feedback module 205 proportionally divides the output voltage and feeds it back to the power management chip 204 to participate in closed-loop regulation and control, ensuring that the output is stable at the target voltage; the feedback module 205 can be a voltage divider composed of two high-precision resistors.

[0062] The overall working process of this implementation method is as follows:

[0063] 1. Initial state: Solenoid valve power supply module 107 is not turned on, switch module 201 is in the off state, and boost module 203 has no voltage input.

[0064] 2. Control signal trigger state: When the control module 108 detects the user's oil injection command and the equipment is in a non-inverted state, it sends a high-level signal to the switch module 201, causing the switch module 201 to conduct, and the power supply voltage is input to the solenoid valve power supply module 107.

[0065] 3. Boost Start-up State: After the switching module 201 is turned on, the input voltage is filtered by the first filter module 202 and then input to the boost module 203, which then starts working. The power management chip 204 simultaneously collects the input voltage, inductor current (or inductor pin voltage), and output voltage feedback signals through the first signal sampling terminal, the second signal sampling terminal, and the third signal sampling terminal, respectively, forming a closed-loop regulation control.

[0066] 4. Output boost voltage status: The boost module 203 boosts the input voltage to the target operating voltage (e.g., 12V), and after being filtered by the second filter module 206, it is output to the solenoid valve 103 to open the solenoid valve 103.

[0067] 5. Feedback and Stabilization: The output voltage is fed back to the power management chip 204 through the feedback module 205 (such as a resistor divider) to dynamically adjust the PWM duty cycle and keep the output voltage constant.

[0068] 6. Shutdown state: After the oil filling is completed, the control module 108 controls the switch module 201 to turn off, the solenoid valve power supply module 107 is de-energized, and the solenoid valve 103 is closed.

[0069] The technical advantages of this embodiment are as follows: the solenoid valve power supply module 107 can efficiently boost the input power supply voltage after receiving the control signal and output a stable working voltage to drive the solenoid valve 103 to work; through the closed-loop control of the power management chip 204, in conjunction with the feedback module 205 and the filtering module, the voltage can be accurately regulated and dynamically stabilized, ensuring that the solenoid valve 103 responds quickly and operates reliably during the oil injection process.

[0070] As an example, such as Figure 3 As shown, the switching module 201 includes a MOSFET Q1, a transistor Q2, a fifth resistor R5, a seventh resistor R7, a ninth resistor R9, and a tenth resistor R10. The source of the MOSFET Q1 and one end of the fifth resistor R5 are connected to one end of the switching module 201. The other end of the fifth resistor R5 is connected to one end of the seventh resistor R7 and the collector of the transistor Q1. The other end of the seventh resistor R7 is connected to the gate of the MOSFET Q1. The drain of the MOSFET Q1 is the other end of the switching module 201. The base of the transistor Q1 is connected to one end of the ninth resistor R9 and one end of the tenth resistor R10. The other end of the ninth resistor R9 is the control terminal of the switching module 201. The emitter of the transistor Q2 and the other end of the tenth resistor R10 are connected to ground.

[0071] The fifth resistor, R5, limits the current flowing from the power input to the control circuit; the seventh resistor, R7, acts as a pull-up resistor, pulling up the gate voltage of MOSFET Q1 when the control signal is invalid, ensuring its reliable turn-off; the ninth resistor, R9, is a current-limiting resistor, limiting the current from the control signal entering the base of transistor Q2; and the tenth resistor, R10, is a pull-down resistor, preventing MOSFET Q2 from being mistakenly turned on due to floating. The operation is as follows: When the control module 108 outputs a high-level control signal to the ninth resistor, R9, the current drives transistor Q2 to conduct, causing its collector potential to drop rapidly. This lowers the gate voltage of MOSFET Q1 below its source, thus turning on MOSFET Q1 and outputting the power supply voltage to the subsequent circuit, starting the power supply. When the control module 108 cancels the control signal or outputs a low level, transistor Q2 is turned off. Its collector voltage is pulled up by the seventh resistor, R7, to near the source voltage of MOSFET Q1, making the gate-source voltage of MOSFET Q1 zero. PMOS transistor Q1 is then turned off, cutting off the power output and stopping the power supply.

[0072] The technical effect of this embodiment is that, through the structure and control logic of the switch module 201 described above, the power supply to the solenoid valve 103 is controlled, which not only ensures the response speed and stability of the action, but also effectively suppresses the power loss in the standby state, thereby improving the energy efficiency and reliability of the overall system.

[0073] As an example, such as Figure 3 As shown, the boost module 203 includes an inductor L1 and a first diode D1. One end of the inductor L1 is the first end of the boost module 203, and the other end of the inductor L1 and the anode of the first diode D1 are connected together to form the second end of the boost module 203. The cathode of the first diode D1 is the third end of the boost module 203.

[0074] The boost module 203 is used to increase the input voltage from the switch module 201 to a target voltage that can drive the solenoid valve 103. The boost module 203 includes an inductor L1 and a first diode D1. During operation, when the control module 108 drives the switch module 201 to conduct, the input voltage is applied across the inductor L1, and the inductor L1 stores magnetic energy. Subsequently, when the switch module 201 is turned off, at the instant the current path is cut off, the inductor L1 maintains current flow because the current cannot change abruptly, forming an induced voltage across its terminals. At this time, the sum of the voltages across the inductor L1 increases to a value higher than the input voltage, causing the first diode D1 to conduct, transferring the energy released by the inductor L1 to the output terminal, thereby realizing boosted output. The first diode D1 plays a role in unidirectional conduction, energy freewheeling, and preventing output voltage backflow during this process, ensuring continuous and stable boosting operation.

[0075] The technical advantage of this embodiment is that the boost module 203 can increase the voltage from the low-voltage battery (e.g., 3.7V) to the target voltage (e.g., 12V), providing sufficient driving voltage for the solenoid valve 103, while also having the advantages of simple circuit structure, fast response, and high efficiency.

[0076] As an example, such as Figure 3 As shown, the feedback module 205 includes an eighth resistor R8 and an eleventh resistor R11. One end of the eighth resistor R8 is the first end of the feedback module 205. The eighth resistor R8 and its other end, together with one end of the eleventh resistor R11, are connected to form the second end of the feedback module 205. The other end of the eleventh resistor R11 is the third end of the feedback module 205.

[0077] The feedback module 205 is used to proportionally divide the output voltage of the boost module 203 and feed it back to the power management chip 204, thereby achieving closed-loop stable control of the output voltage. The feedback module 205 includes an eighth resistor R8 and an eleventh resistor R11. During operation, the high voltage (e.g., 12V) output by the boost module 203 is divided in series by the eighth resistor R8 and the eleventh resistor R11, forming a stable intermediate voltage (e.g., 1.2V) at the connection point of the two resistors. This voltage is input as a feedback signal to the feedback sampling terminal of the power management chip 204. Based on this feedback voltage, the power management chip 204 compares it with its internal reference voltage and automatically adjusts the duty cycle of the PWM control signal, thereby achieving closed-loop regulation and voltage regulation control of the output voltage of the boost module 203.

[0078] The technical effect of this embodiment is that it enables real-time monitoring, automatic adjustment and high-precision stable output of the output voltage, ensuring that the solenoid valve 103 always obtains the appropriate driving voltage under different working conditions, effectively improving the reliability and intelligence of the power supply system.

[0079] As an example, the first filter module 202 includes a fourth capacitor C4, a fifth capacitor C5, and a sixth capacitor C6. One end of the fourth capacitor C4, one end of the fifth capacitor C5, and one end of the sixth capacitor C6 are connected together to form the first end of the first filter module 202, and the other end of the fourth capacitor C4, the other end of the fifth capacitor C5, and the other end of the sixth capacitor C6 are connected together to form the second end of the first filter module 202.

[0080] The first filtering module 202 is used to filter the input voltage output by the switching module 201 to improve the stability of the input voltage and suppress high-frequency noise and voltage ripple.

[0081] As an example, the second filter module 206 includes a seventh capacitor C7, an eighth capacitor C8, and a ninth capacitor C9. One end of the seventh capacitor C7, one end of the eighth capacitor C8, and one end of the ninth capacitor C9 are connected together to form the first end of the second filter module 206, and the other end of the seventh capacitor C7, the other end of the eighth capacitor C8, and the other end of the ninth capacitor C9 are connected together to form the second end of the second filter module 206.

[0082] The second filter module 206 is used to filter the output voltage of the boost module 203 to reduce the ripple and noise of the solenoid valve drive power supply and improve the stability and electromagnetic compatibility of the output voltage.

[0083] Furthermore, the second filter module 206 also includes a second diode D2 and a twelfth capacitor C12. The cathode of the second diode D2 and one end of the twelfth capacitor C12 are connected together and then connected to one end of the ninth capacitor C9. The anode of the second diode D2 and the other end of the twelfth capacitor C12 are connected to ground.

[0084] The circuit works as follows: When the control module 108 issues an oil filling command and detects that the atomizing device is in a non-inverted state, the control terminal outputs a high-level signal to the switching module 201, causing the ninth resistor R9 to transmit the signal to the base of transistor Q2, turning on transistor Q2. At this time, MOSFET Q1 turns on, allowing the power supply voltage to enter the power supply path. The power supply voltage first passes through the first filter module 202, composed of the fourth capacitor C4, the fifth capacitor C5, and the sixth capacitor C6, to perform composite filtering on the input power supply, and is output to the input terminal of inductor L1. In the boost module 203, inductor L1 begins to store energy. When the power management chip 204 controls the switching cycle to open, inductor L1 releases energy, and current flows through the first diode D2, outputting a boost voltage. This output voltage is further filtered by the second filter module 206, composed of the seventh capacitor C7, the eighth capacitor C8, and the ninth capacitor C9, and is then stably output to the solenoid valve 103, driving it to open. Simultaneously, the feedback module 205, composed of the eighth resistor R8 and the eleventh resistor R11, performs voltage division sampling on the output voltage and transmits the feedback voltage to the feedback sampling terminal of the power management chip 204, forming a closed-loop control to dynamically adjust the PWM duty cycle and stabilize the output voltage. After oil filling is completed, the control module 108 cancels the command, outputs a low level to turn off transistor Q2 and MOSFET Q1, cuts off the power supply, closes the solenoid valve 103, and the oil filling ends.
