DETAILED DESCRIPTION

[0040] The present invention is further described in detail below by means of specific embodiments in conjunction with the accompanying drawings. Similar elements in different embodiments are numbered with associated similar elements. In the following embodiments, many detailed descriptions are provided to enable the present application to be better understood. However, those skilled in the art will readily appreciate that some of the features may be omitted under different circumstances, or may be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification. This is to avoid the core portion of the present application being overwhelmed by excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail. They can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0041] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various embodiments. Furthermore, the steps or actions in the method description may be reordered or adjusted in a manner readily apparent to those skilled in the art. Therefore, the various sequences in the specification and drawings are provided solely for the purpose of clearly describing a particular embodiment and are not intended to be mandatory, unless otherwise specified.

[0042] The serial numbers assigned to components herein, such as "first," "second," etc., are used solely to distinguish the objects being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0043] Electric heating atomization equipment generally involves switching control of heating functions, such as switching heating power, or switching heating or non-heating functions. Another example is that it has two heating elements, which can control one of them to heat or both to heat. Among them, double-row switches are commonly used in atomization equipment. The double-row switch has multiple toggle positions. By connecting different resistors to the pins, when in different toggle positions, the resistance, voltage or current connected to the input / output interface is different. The processor of the atomization equipment (usually a microprocessor) identifies the position of the double-row switch by identifying the resistance, voltage or current of the input circuit.

[0044] like Figure 1 As shown, taking a double-row switch with six pins as an example, an existing switch circuit is connected to the input / output interface of the processor (such as Figure 1 In the AD1_WK circuit, pins 1 and 3 are connected to resistor circuits, with resistors R2 and R5 having different resistance values. Pins 4 through 6 are left floating. When the dual-row switch is in the first position, pins 1 and 2 are connected, forming a loop with resistors R2 and R47. When the dual-row switch is in the second position, pins 2 and 3 are connected, forming a loop with resistors R5 and R47. By identifying the current output by AD1_WK, the resistance of the circuit can be calculated, and the connection between pins 1 and 2 or between pins 2 and 3 can be determined. This allows the switch's position to be identified, enabling control of the heating function.

[0045] However, for this type of switch circuit, no matter whether pin 1 is connected to pin 2 or pin 2 is connected to pin 3, the resistor is always energized, resulting in power consumption. For battery-powered atomizers, even in standby mode, the switch circuit continues to consume power, affecting battery life.

[0046] like Figures 2 to 5 As shown, an embodiment of the present application provides a switching circuit 100, which may include a double-row switch 10, multiple charging modules 21, multiple energy storage modules 22 and multiple discharge modules 23. The charging module 21, the energy storage module 22 and the discharge module 23 are respectively connected to the pins of the double-row switch 10, and the double-row switch 10 has at least two toggle gears.

[0047] like Figure 2 、 Figure 4 and Figure 5 As shown, when the double-row switch 10 is a six-pin double-row switch, the switch circuit 100 may have two energy storage modules 22, two charging modules 21 and two discharging modules 23. Figure 3As shown, when the dual-row switch 10 is an eight-pin dual-row switch, the switch circuit 100 can have two energy storage modules 22, three charging modules 21, and three discharging modules 23. The present embodiment does not limit the number of toggle positions (pins) of the dual-row switch 10. For ease of description, the present embodiment assumes that the dual-row switch 10 is a six-pin dual-row switch with two toggle positions.

[0048] The charging module 21 is configured to output a high-level voltage signal; the charging module 21 may be connected to the power supply component 50, or connected to the microprocessor 30 to obtain a high-level output and output a high level. Figure 4 As shown, the charging module 21 can be connected to the high-level end of VDD and can also include resistors (such as R55 and R47) to output a high-level voltage signal through pin 3 of the double-row switch 10.

[0049] The energy storage module 22 is configured to store the electrical energy output by the charging module 21 when connected to the charging module 21; the energy storage module 22 may include at least one energy storage device, which may be a capacitor or other electrical device with energy storage capability.

[0050] All discharge modules 23 are configured to be electrically connected to the same external input / output interface 31. When the discharge module 23 is connected to the energy storage module 22, it is configured to release the electrical energy of the energy storage module 22 to the input / output interface 31. Because the microprocessor 30 has a limited number of input / output interfaces 31, which are important circuit design resources, the switch circuit 100 of the present application can occupy only one input / output interface 31 of the microprocessor 30.

[0051] When the double-row switch 10 is placed in a toggle position, a corresponding charging module 21 on one row of the double-row switch 10 is connected to a corresponding energy storage module 22 to form a charging circuit, and a corresponding energy storage module 22 on the other row of the double-row switch 10 is connected to a discharging module 23 to form a discharging circuit.

[0052] At least two toggle positions correspond to at least two charging circuits and at least two discharging circuits, and the time constant of each discharging circuit is different; or, the charging time constant of each charging circuit is different, and the time constant of each discharging circuit is different. Figure 4 As shown, the six-pin double-row switch has two toggle positions, corresponding to two charging circuits and two discharging circuits; Figure 3 As shown, the eight-pin double-row switch has three toggle positions, corresponding to three charging circuits and three discharging circuits.

[0053] like Figure 4As shown, when the gear is in the first gear, pin 1 is connected to pin 2, and pin 4 is connected to pin 5. At this time, the discharge module 23 on the left is connected to the energy storage module 22, forming a discharge circuit, that is, the resistor R46 is connected to the capacitor C40, and the electric energy stored in the capacitor C40 is output to the input / output interface 31 (as shown in FIG. Figure 4 the energy storage module 22 on the right is connected to the charging module 21 to form a charging circuit, that is, the resistor R47 is connected to the capacitor C41, and the capacitor C41 obtains the high-level voltage signal output by VDD_IN through the resistor R47 for charging and energy storage.

[0054] like Figure 5 As shown, when the gear is in the second gear, pin 2 is connected to pin 3, and pin 5 is connected to pin 6. At this time, the energy storage module 22 on the left is connected to the charging module 21 to form a charging circuit, that is, the resistor R55 is connected to the capacitor C40, and the capacitor C40 obtains the high-level voltage signal output by VDD_IN through the resistor R55 to charge and store energy; the discharge module 23 on the right is connected to the energy storage module 22 to form a discharge circuit, that is, the resistor R56 is connected to the capacitor C41, and the electric energy stored in the capacitor C41 is output to the input / output interface 31 (as shown in FIG. Figure 5 AD1_WK in ).

[0055] When the gear is switched, the energy storage module 22 is alternately connected to the charging module 21 and the discharge module 23 connected to the same row of pins, forming a charging circuit in one gear to store energy, and forming a discharge circuit in the other gear to discharge. When the gear is not switched, only one energy storage module 22 is charging. After charging is completed, it no longer consumes electricity and does not consume power in standby mode, which can meet the low power consumption requirements of the atomization device. The time constant of each discharge circuit is different. The processor can determine which discharge circuit is discharging by identifying the discharge time, thereby identifying which gear the double-row switch 10 is in.

[0056] like Figure 2 、 Figure 4 and Figure 5 As shown, in one embodiment, on the same row of pins, the pin connected to the energy storage module 22 is set between the pins connected to the charging module 21 and the discharge module 23; in a general double-row switch 10, one gear will connect two adjacent pins in the same row. When a six-pin double-row switch is used, the energy storage module 22 is connected to the middle pin, as shown in FIG. Figure 4 and Figure 5 Pins 2 and 5 in the circuit. In this case, a six-pin double-row switch commonly used on the market can be used, which can reduce costs and does not require a customized double-row switch.

[0057] like Figure 2 、 Figure 4 and Figure 5 As shown, in some embodiments, the charging module 21 of the charging circuit and the discharging module 23 of the discharging circuit corresponding to the same toggle gear are connected to symmetrical pins in two rows of pins. Figure 4 and Figure 5 As shown, pin 1 is connected to a discharge module 23, and pin 4 symmetrical to pin 1 is connected to a charging module 21; pin 3 is connected to a charging module 21, and pin 6 symmetrical to pin 3 is connected to a discharge module 23.

[0058] The symmetrical connection method can be directly applied to the existing six-pin double-row switch, and has a regular pattern, making it convenient for operators to connect the circuit without making mistakes.

[0059] like Figure 4 and Figure 5 As shown, in one embodiment, the energy storage module 22 may include capacitors, with each energy storage module 22 having a different capacitor capacitance value. Based on the characteristic of capacitors that block direct current but pass alternating current, the capacitors of the energy storage modules 22 in the charging circuit no longer absorb electrical energy after being charged, thereby meeting the functional requirements of the energy storage module 22. Because the discharge time constant of each discharge circuit is different, different resistors / capacitors are required in the discharge circuits. Therefore, capacitors with different capacitance values can be used to ensure that the discharge time constant of each discharge circuit is different.

[0060] like Figure 4 and Figure 5 As shown, in one embodiment, when the double-row switch 10 is a six-pin double-row switch, the capacitors of the two energy storage modules 22 are different, and the discharge module 23 may include a resistor. The resistance value of the resistor of each discharge module 23 may be the same. When the capacitors of the two energy storage modules 22 are different, the resistors of the discharge modules 23 may be the same. The different capacitors of the energy storage modules 22 can ensure that the discharge time constants of the two discharge circuits are different. The processor can determine which discharge circuit is discharging by identifying the discharge time, thereby identifying which gear the double-row switch 10 is in. Using the same resistor in this case can, on the one hand, reduce costs by eliminating the need for multiple resistors with different resistance values, and on the other hand, reduce the difficulty of circuit connection and avoid errors in resistor welding.

[0061] like Figure 4 and Figure 5As shown, in one embodiment, the charging module 21 may include a resistor, and the resistance value of the resistor of each charging module 21 may be the same. The resistance value of the resistor of the charging module 21 may be the same as the resistance value of the resistor of the discharge module 23. The switching circuit 100 provided in the embodiment of the present application mainly realizes the recognition of the gear position through the discharge circuit with different discharge time constants. The charging time constants of each charging circuit may be the same or different. At this time, the same resistor is used. On the one hand, it can reduce costs and do not require multiple resistors with different resistance values. On the other hand, it can reduce the difficulty of circuit connection and avoid errors in resistor welding.

[0062] like Figure 3 As shown, when the dual-row switch 10 has at least three toggle positions, for example, an eight-pin dual-row switch with three toggle positions, the switch circuit 100 may include two energy storage modules 22, three charging modules 21, and three discharge modules 23. The four pins on one row are respectively connected to one energy storage module 22, two charging modules 21, and one discharge module 23, while the four pins on the other row are respectively connected to one energy storage module 22, one charging module 21, and two discharge modules 23. To ensure that the discharge time constant of each discharge circuit is different, the capacitance value of the capacitor of each energy storage module 22 is different, and the resistance value of the resistor of each discharge module 23 is different.

[0063] When in the first gear, pin 1 and pin 2 are connected to form a charging circuit, and pin 5 and pin 6 are connected to form a discharging circuit; when in the second gear, pin 1 and pin 3 are connected to form a discharging circuit, and pin 5 and pin 7 are connected to form a charging circuit; when in the third gear, pin 1 and pin 4 are connected to form a charging circuit, and pin 5 and pin 8 are connected to form a discharging circuit.

[0064] It can be seen that the switch circuit 100 and the double-row switch 10 provided in the embodiment of the present application are not limited to six-pin double-row switches or eight-pin double-row switches. As long as it is ensured that when in a gear, one charging circuit is connected and one discharging circuit is connected, the discharge circuit outputs a voltage signal that can be recognized by the processor as the position of the switch gear. The charging circuit charges the energy storage module 22. When switching to the next gear, the energy storage module 22 corresponding to the charging circuit of the previous gear is connected to the discharge module 23 corresponding to the next gear, forming a new discharge circuit, which can be discharged directly. Before switching to the next gear, the energy storage module 22 is stored before the next gear is switched, and no additional energy is consumed.

[0065] like Figure 6As shown, the embodiment of the present application further provides a control device 200, which may include a timing module 32, an identification module 33, a processing module 34 and the switch circuit 100 described in the above embodiment.

[0066] In one embodiment, the control device 200 may include a microprocessor 30, which may include a timing module 32, an identification module 33, and a processing module 34. The microprocessor 30 may be a microprocessor 30 having a timer or a timer, and may be a microprocessor 30 having a sleep function. The microprocessor 30 having the sleep function may have the advantage of low power consumption.

[0067] All the discharge modules 23 are configured to be electrically connected to the same input / output interface 31 of the processing module 34 .

[0068] The processing module 34 is configured to be awakened when a high-level voltage is input to the input / output interface 31. The processing module 34 may have a sleep function and will be awakened when a high-level voltage signal output by the discharge circuit of the switch circuit 100 is received, thereby correspondingly switching the switch gear of the dual-row switch 10.

[0069] The timing module 32 is configured to calculate the discharge time required for the high-level voltage input by the discharge module 23 through the input / output interface 31 to drop to a preset voltage (e.g., 70% of the high-level voltage or 0V). The timing module 32 may be a timer of the microprocessor 30 to implement a timing function. For conventional microprocessors, a voltage between 0.7VDD and VDD is identified as a high level.

[0070] The identification module 33 is configured to determine whether the discharge time is within a preset time range. If so, it outputs a corresponding first identification signal. The first identification signal is used to identify the current toggle position of the discharge module 23. Each time range corresponds to a toggle position setting. The identification module 33 can be implemented using a comparator of the microprocessor 30. By comparing multiple preset time ranges, each time range corresponding to a discharge time constant design of the discharge circuit, the identification module 33 can identify the position of the double-row switch 10.

[0071] In one embodiment, when the atomizing device is first connected to the power supply assembly 50 and just powered on, the energy storage module 22 of the discharge circuit corresponding to the current gear of the switch circuit 100 has not been charged and cannot be discharged. At this time, the microprocessor 30 cannot identify which position the current gear is. Figure 4 As shown, when the device is just powered on, pins 1 and 2 are electrically connected, capacitor C40 is connected to resistor R46, but capacitor C40 is not charged at this time. At this time, the microprocessor 30 needs to pre-charge the energy storage module 22 of the discharge circuit.

[0072] The processing module 34 is configured as follows: after the processing module 34 is powered on, it outputs a high-level voltage signal of a preset duration to the discharge module 23 of the discharge circuit corresponding to the currently engaged gear position through the input / output interface 31, and the energy storage module 22 of the discharge circuit stores electrical energy; after the processing module 34 stops outputting a high-level voltage signal, the discharge module 23 of the discharge circuit releases electrical energy to the input / output interface 31.

[0073] The timing module 32 is configured to calculate the discharge time for the high-level voltage inputted by the discharge module 23 of the discharge circuit through the input / output interface 31 to decrease to a preset voltage.

[0074] The identification module 33 is configured to determine whether the discharge time is within a preset time range. If so, it outputs a corresponding first identification signal, which is used to identify the current toggle position of the discharge module 23. One time range corresponds to one toggle position setting.

[0075] That is to say, the energy storage module 22 of the discharge circuit corresponding to the current gear can be pre-charged through the input / output interface 31, and then the discharge circuit where the energy storage module 22 is located is discharged. The output discharge time is calculated by the timing module 32, and the current gear position can be identified through the identification module 33.

[0076] Alternatively, the next gear can be identified by switching the gear switch to the next gear. Figure 4 As shown, if the device has just been powered on, the double-row switch 10 is in the first gear, the energy storage module 22 connected to pin 2 is not charged, and the energy storage module 22 connected to pin 5 is charged by the charging module 21 on pin 4. After switching to the second gear, the energy storage module 22 connected to pin 5 is discharged by the discharging module 21 on pin 6, and the energy storage module 22 connected to pin 2 is charged by the charging module 21 on pin 3. It is also possible to pre-charge the energy storage module corresponding to each gear by switching each gear.

[0077] like Figure 7 As shown, an embodiment of the present application further provides an atomization device, which may include: a heating component 40, a power supply component 50 and the control device 200 described in the above embodiment.

[0078] The heating assembly 40 is configured to heat the aerosol matrix; the heating assembly 40 can be implemented using a heating tube, a heating plate, a heating mesh, or the like. The power supply assembly 50 is configured to supply power to the atomizing device and includes a battery. The control device 200 is configured to control the operation of the heating assembly 40 according to the current toggle position of the double-row switch 10. For example, the power supply assembly 50 can be controlled to supply power to the heating assembly 40 or not, or to supply power at different power levels.

[0079] To sum up, the switching circuit 100, the control device 200 and the atomization device provided in the embodiment of the present application are connected to a charging module 21, an energy storage module 22 and a discharge module 23 through a double-row switch 10. No matter which toggle gear the double-row switch 10 is in, one discharge circuit is connected and one charging circuit is connected. At this time, the energy storage module 22 of the discharge circuit is discharged and the energy storage module 22 of the charging circuit is charged; when the gear is switched, the other discharge circuit is connected and the other charging circuit is connected. At this time, the energy storage module 22 of the discharge circuit is the energy storage module 22 of the charging circuit of the previous gear; if the gear is not switched, the energy storage module 22 does not discharge. Discharge after switching the switch does not require re-powering and no additional energy is consumed. It can achieve no standby power consumption and meet the low power consumption requirements.
