[0002] At present, the atomizer device basically uses polyphenylene sulfide (PPS) film capacitive gas sensor as the suction sensing device.

[0028] The present invention is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are intended to enable the present application to be better understood. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods. In some cases, some operations related to the present application are not shown or described in the specification, in order to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0029] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0030] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0031] Existing products have the problem of poor pressure detection stability. The present application aims to solve the problem of poor pressure detection stability of the atomization component.

[0032] First aspect: a piezoresistive MEMS (Micro Electro Mechanical System, referred to as micromechanical) sensing element is provided in the airway. Compared with the capacitive gas sensor, the piezoresistive MEMS sensing element converts the gas flow and pressure inside the atomizer assembly into a resistance difference signal by sensing and collecting the gas flow and pressure inside the airway, that is, the gas flow and pressure inside the airway affect the surface pressure sensing of the silicon material inside the piezoresistive MEMS sensing element through the airway, changing the resistance difference of the sensor, and then the resistance difference is converted into a potential difference signal through the conversion circuit, and the potential difference signal is output to the processor. The processor collects the change of the potential difference signal of the sensor by electrically connecting the output end of the sensor to judge the change of the gas flow in the airway inside the atomizer assembly.

[0033] The second aspect: connect the processor to the display element. The piezoresistive MEMS sensing element converts the gas pressure inside the atomization component into a resistance difference signal, and then converts it into a potential difference signal through a conversion circuit and transmits it to the processor for identification and processing. Sensing the suction pressure inside the airway will change the resistance change inside the piezoresistive MEMS sensing element, and the change in resistance will be converted into a potential difference change and transmitted to the processor. The processor then uses display elements and other methods to achieve a progressive display effect based on the collected potential difference changes. For example, when suctioning, the indicator light gradually brightens as the suction pressure increases, and when not suctioning, the indicator light gradually dims as the suction pressure decreases.

[0034] The technical solution of this application is described in detail below with reference to the accompanying drawings.

[0035] See also Figure 1 The figure discloses an atomization assembly 10, including a shell 11, a microphone 12, a processor 13 and a display element 14, the shell 11 includes an airway; a piezoresistive MEMS sensing element 121, the piezoresistive MEMS sensing element 121 is a component of the microphone 12, and is arranged in the airway to output a potential difference signal in response to the pressure in the airway; the processor 13 is electrically connected to the piezoresistive MEMS sensing element 121 to obtain the potential difference signal of the piezoresistive MEMS sensing element 121; the display element 14 is electrically connected to the processor 13; the processor 13 adjusts the potential difference signal to be positively correlated with the current flowing through the display element 14, and the display element 14 displays gradually according to the magnitude of the current flowing through it.

[0036] The microphone 12 in the atomizer assembly 10 of the present application includes a piezoresistive MEMS sensing element 121, and the change in the gas pressure after detection is mainly reflected in the change in its own resistance value. The change in resistance value is relatively stable compared with the change in capacitance value in the prior art, and is basically not affected by metal dust and other debris, thereby improving the stability of the pressure detection of the atomizer assembly 10. And by utilizing the good linearity of the voltage difference signal output by the piezoresistive MEMS sensing element 121, the atomizer assembly containing the circuit structure can realize the effect of corresponding gradual display according to the change in the suction pressure during the user's inhalation process.

[0037] It should be noted that the above-mentioned gradual display may include a gradual display of display brightness and / or a gradual display of display area. It is understandable that the structure illustrated in this embodiment does not constitute a specific limitation on the atomization assembly 10. In other embodiments, the atomization assembly 10 may include more or fewer components than shown in the figure, or combine certain components, or split certain components, or arrange the components differently. The illustrated components may be implemented in hardware, software, or a combination of software and hardware.

[0038] See also Figure 2 The atomizing assembly 10 shown in the figure also includes a metal-oxide-semiconductor (MOS) tube 15, the drain of the MOS tube 15 is grounded, the gate of the MOS tube 15 is connected to the processor 13, and the processor 13 adjusts the potential difference signal to be positively correlated with the drain current output by the MOS tube 15; the display element 14 is connected to the source of the MOS tube 15 to display gradually according to the drain current. By setting the MOS tube 15 to adjust the drain current, the current at the display element 14 can be adjusted, thereby realizing the gradual display of the display element 14.

[0039] See also Figure 3 , the output end of the piezoresistive MEMS sensing element 121 is electrically connected to the processor 13, and the processor 13 is electrically connected to the gate of the MOS tube 15. The piezoresistive MEMS sensing element 121 outputs a potential difference signal, which indicates that a suction action is detected, that is, the piezoresistive MEMS sensing element 121 outputs a potential difference signal due to the user's suction, and the potential difference signal is output to the processor 13. Since the output potential difference signal of the piezoresistive MEMS sensing element 121 is positively correlated with the suction pressure, from the perspective of ergonomics, in a suction action, the suction pressure detected by the piezoresistive MEMS sensing element 121 generally rises first and then falls. Due to the piezoresistance characteristics of the piezoresistive MEMS sensing element 121, the potential difference signal output by the piezoresistive MEMS sensing element 121 increases first and then decreases; correspondingly, in the previous stage, the drain current of the MOS tube 15 gradually increases, and in the circuit where the display element 14 electrically connected to the MOS tube 15 is located, the current flowing through the display element 14 gradually increases, so that the brightness of the display element 14 gradually increases, producing a gradual display effect.

[0040] Of course, the voltage difference signal is generally small and may not reach the conduction voltage of the MOS tube 15. In a further embodiment, an amplifier device may be added between the output end of the piezoresistive MEMS sensing element 121 and the processor 13 to amplify the potential difference signal. Alternatively, the processor 13 processes the output digital signal to control the voltage supplied to the gate of the MOS tube 15 so that the gate voltage of the MOS tube 15 reaches the conduction threshold, thereby gradually adjusting the drain current output by the MOS tube 15.

[0041] See also Figure 4 Considering the power economy and the connection display problem between different puffing actions, firstly, for the power economy, in order to produce the gradual display effect corresponding to the puffing action, it is necessary to ensure that during one puffing process, the piezoresistive MEMS sensing element 121 is always kept in the detection state, so as to reflect the different puffing pressure changes during the puffing process.

[0042] Furthermore, during different puffing processes, it is also necessary to ensure that the piezoresistive MEMS sensing element 121 is always in a detection state. For the piezoresistive MEMS sensing element 121, it is always required to maintain a power supply state, and any output potential difference signal of the piezoresistive MEMS sensing element 121 caused by any puffing action will be processed by the processor 13, resulting in a large power consumption.

[0043] In order to solve the problems of power economy and connection display between different puffing actions, in some embodiments, a sampler 16 is provided at the output end of the piezoresistive MEMS sensing element 121 to sample the output potential difference signal of the piezoresistive MEMS sensing element 121 at a predetermined frequency, and only a predetermined number of sampled data will be transmitted to the next device. In this way, the subsequent processor 13 will not be in a working state all the time, saving power loss.

[0044] In a specific embodiment, the atomizer assembly 10 further includes a register 17, and the potential difference signal includes discrete values, which are stored in the register 17. The values ​​stored in the register 17 are transmitted to the processor 13 and mapped to the brightness value of the display lamp bead. The processor 13 converts the discrete multiple potential difference values ​​into digital signals, transmits them to the register 17, and controls the display brightness of the display element 14 according to the values ​​in the register 17. For example, taking the duration of a general puff action as 0.4 seconds as an example, a sampling interval of 0.05 seconds can be set to obtain 8 discrete potential difference signals, which are transmitted to the register 17 at a time, and then the display brightness of the display element 14 is adjusted. It can be understood that considering the situation of visual persistence, multiple discrete potential difference signals are displayed in sequence in a short time, and the user experience will not cause the problem of intermittent display of the display element during the puffing process. The technical effect corresponding to setting register 17 can also be that, considering that the gradient effect corresponding to the display of a puff process may be from dark to light to dark, the initial sampling of the next puff action may be sampling the corresponding low or no potential difference value, so that the value of the previous puff action can be temporarily stored in register 17 to solve the problem of poor initial display of the next puff action.

[0045] In one embodiment, a memory 18 is provided, the memory 18 is electrically connected to the processor 13, and stores a corresponding look-up table (LUT for short), the LUT associates the magnitude of the potential difference signal with the display brightness level, for example, associates the magnitude of the potential difference signal after analog-to-digital conversion with the display brightness level; in a specific embodiment, the display brightness level is divided into 6 levels, the processor 13 converts the potential difference signal into a digital signal, obtains the magnitude of the digital signal, accesses the memory 18 electrically connected thereto, obtains the display brightness level corresponding to the magnitude of the digital signal, and controls the brightness of the display element 14 according to the output display brightness level. For example, taking the duration of a general puff action as 0.4 seconds, a sampling interval of 0.05 seconds can be set, thereby obtaining 8 potential difference signals, and the 8 potential difference signals are associated with 8 display brightness levels in the LUT, thereby adjusting the display brightness of the display element 14. The technical effect corresponding to setting the memory 18 can also be that, considering that the gradient effect corresponding to the display of a puff process may be from dark to light to dark, the initial sampling of the next puff action may be sampling the corresponding low or no potential difference value, so that the memory 18 can also temporarily store the value of the previous puff action to solve the problem of poor initial display of the next puff action.

[0046] See also Figure 5 The piezoresistive MEMS sensing element 121 includes a conversion circuit, which includes two balancing resistors and two piezoresistive resistors. The two balancing resistors and the two piezoresistive resistors form a bridge circuit. The input end of the bridge circuit is connected to a power supply, and the output end of the bridge circuit is connected to the processor 13. The piezoresistive resistor is the sensing part of the piezoresistive MEMS sensing element 121.

[0047] The output terminals V- and V+ of the conversion circuit output a potential difference. The greater the potential difference, the greater the resistance change, and the greater the pressure difference in the airway. The input terminal of the conversion circuit is connected to the power supply. Specifically, the input terminals U- and U+ can be directly connected to the positive and negative poles of the power supply, or the input terminals U- and U+ are connected to the processor 13 to achieve connection with the power supply. The piezoresistive resistor of the conversion circuit serves as the sensing part of the piezoresistive MEMS sensing element 121, which can produce deformation. Specifically, its resistance value changes with the difference between the gas pressure in the airway and the external gas pressure. The above changes can be positively correlated or negatively correlated. The positive correlation can be understood as increasing with the increase of the pressure difference and decreasing with the decrease; the negative correlation can be understood as decreasing with the increase of the pressure difference and increasing with the decrease. Regardless of the above methods, under the action of the processor 13, the correlation between the resistance value and the display state of the display element 14 is established.

[0048] In the figure, R1 and R2 are balancing resistors, R3 and R4 are piezoresistive resistors. The resistance of the piezoresistive resistors will change when the gas and pressure in the airway change. The greater the resistance change, the greater the pressure difference in the airway.

[0049] See also Figure 6 The processor 13 may include a receiving module 131 for receiving a potential difference signal, a processing module 132 for processing the potential difference signal to generate a display execution signal, and a sending module 133 for sending the display execution signal to the MOS tube 15. The processor 13 and the piezoresistive MEMS sensing element 121 may be integrated on one circuit board, or integrated on two circuit boards respectively and connected through lines.

[0050] The gradual display may include a display brightness increase, a display brightness decrease, a display area increase, a display area decrease, a display color change from a cold color to a warm color, a display color change from a warm color to a cold color, etc. The above changes in display brightness, area, and color are all intended to establish a correlation with the suction pressure. For example, the change in display brightness reflects the increase or decrease in suction pressure, the size of the area reflects the increase or decrease in suction pressure, the color changes from cold color to warm color means the suction pressure increases, and the color changes from warm color to cold color means the suction pressure decreases.

[0051] In addition, in order to minimize the visual sense of fragmentation, the above display brightness, display area, and display color adopt a gradual change (gradual change) method during the change process. Taking display brightness as an example, when the display brightness gradually becomes stronger, the suction pressure gradually increases, and when the display brightness gradually becomes weaker, the suction pressure gradually decreases. Taking display area as an example, when the display area gradually becomes stronger, the suction pressure gradually increases, and when the display area gradually becomes weaker, the suction pressure gradually decreases.

[0052] In one embodiment, the display element 14 includes a single lamp bead, and the display brightness of the single lamp bead is adjustable. The display brightness of the single lamp bead is positively correlated with the resistance difference. When the display brightness of the single lamp bead becomes stronger, the resistance difference becomes larger, and the further suction pressure becomes larger; when the display brightness of the single lamp bead becomes weaker, the resistance difference becomes smaller, and the further suction pressure becomes smaller.

[0053] In one embodiment, the display element 14 includes a plurality of lamp beads, the plurality of lamp beads are arranged in a row, the number of the plurality of lamp beads that light up is adjustable, and the number of the lamp beads that light up is positively correlated with the resistance difference. As the number of the lamp beads that light up increases, the resistance difference increases, and the further suction pressure increases; as the number of the lamp beads that light up decreases, the resistance difference decreases, and the further suction pressure decreases.

[0054] If there are multiple lamp beads, the colors of the multiple lamp beads can be the same or different. For lamp beads with different colors, some lamp beads can be defined as warm tones, and some lamp beads can be defined as cold tones. By switching the lighting of lamp beads with different tones, the change of suction pressure is reflected.

[0055] The lamp beads are LED lamps or incandescent lamps.

[0056] The above mainly introduces the case where the display element 14 can be a lamp bead. In some embodiments, the display element 14 can also include a display screen.

[0057] The display screen can define an area for displaying the puffing status. Of course, a partial area or the entire area of ​​the display screen can be defined as the puffing display area.

[0058] In one embodiment, the suction display area can be defined as having adjustable display brightness, and the display brightness is positively correlated with the resistance difference. When the display brightness becomes stronger, the resistance difference becomes larger, and the further suction pressure becomes larger; when the display brightness becomes weaker, the resistance difference becomes smaller, and the further suction pressure becomes smaller.

[0059] Then, the display screen includes multiple areas with adjustable display brightness or multiple areas with adjustable display area, which can be used to gradually display more status information of the atomization component 10.

[0060] In one embodiment, the suction display area can be defined as an adjustable display area, and the display area is positively correlated with the resistance difference. When the display area increases, the resistance difference increases, and the further suction pressure increases; when the display area decreases, the resistance difference decreases, and the further suction pressure decreases.

[0061] In one embodiment, some areas may be defined as warm tones, and some areas may be defined as cold tones. By switching the lighting of areas with different tones, the change of the suction pressure is reflected.

[0062] It should be noted that the display element 14 is disposed on the housing 11, and the housing 11 is defined as an upstream end and a downstream end according to the direction from close to far from the oral cavity, wherein the upstream end is used to form a suction nozzle. The display element 14 can be installed on the peripheral surface of the housing 11, and can also be installed on the downstream end.

[0063] See also Figure 7, the figure discloses an atomization device, which includes the above-mentioned atomization component 10 and the power supply component 20. The power supply component 20 is used to provide electrical energy to the atomization component 10, and the atomization component 10 is used to heat the atomization matrix into an aerosol. At least one of the display brightness adjustable areas or the display area adjustable areas of the display element 15 displays the remaining power of the power supply component 20. For example, a display brightness adjustable area of ​​the display element 15 contains multiple display lamp beads, and the brightness of the display lamp beads or the depth of the display color show the different remaining power of the power supply component 20. More specifically, for display lamp beads of the same color system, the different remaining power states of the power supply component 20 can be reflected by the display brightness or display color gradient of light red, red, and dark red. The electronic atomization device can be a disposable product or a cartridge-changing product. For a disposable electronic atomization device, the atomization component 10 and the power supply component 20 are fixedly connected; for a cartridge-changing electronic atomization device, the atomization component 10 and the power supply component 20 are detachably connected, and the atomization component 10 and the power supply component 20 can be replaced according to the usage.

[0064] It is understood that the structure illustrated in this embodiment does not constitute a specific limitation on the atomization device. In other embodiments, the atomization device may include more or fewer components than shown in the figure, or combine certain components, or split certain components, or arrange the components differently. The components shown in the figure may be implemented in hardware, software, or a combination of software and hardware.

[0065] The above specific examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. For those skilled in the art of the present invention, some simple deductions, deformations or substitutions can be made based on the idea of ​​the present invention.
