Abstract
Description
Technical Field
[0001] The present disclosure relates to the technical fields of magnetic pneumatic control and electronic atomizers, and in particular to a pneumatic magnetic sensor device and an electronic atomizer based on preventing accidental touch. Background Art
[0002] Electronic cigarettes / electronic atomizers generally have a built-in microphone switch, which senses the negative pressure generated by the user's inhalation, thereby starting the electronic cigarette and promoting the electronic cigarette to atomize the atomizing medium to form an atomized aerosol for the user to inhale.
[0003] Usually, the switch of the electronic cigarette microphone adopts a capacitive structure, such as the existing patent CN217564984U, etc. This structure controls the state of the atomization switch by the change of the capacitor charge. Specifically, when the user inhales, the film is deformed, thereby activating the atomization switch. However, when using the electronic cigarette, some smoke oil and / or condensate are easily attached to the film. In addition, in the prior art, the surface of the film is plated with metal, so that the smoke oil and / or condensate are used as other media for controlling the change of charge, thereby causing interference caused by the attachment of the smoke oil and / or condensate. Over time, the film will adhere to more smoke oil and / or condensate, causing structural corrosion, thereby causing inaccurate charge changes when the user inhales the electronic cigarette, resulting in the atomization switch being affected, thereby affecting the normal operation of the atomization component. Moreover, when the film is corroded, if the user has misoperation behavior, such as blowing air to the electronic atomizer, continuous blowing and inhaling, etc., it is easy to cause the electronic atomizer to be mistakenly started, resulting in excessive atomization of the smoke oil, resulting in dry burning or even damage to the atomization switch.
[0004] Therefore, the structure of the electronic cigarette microphone switch needs to be improved to prevent film corrosion, such as using magnetic blocks as the atomization switch medium. However, when using magnetic blocks, the magnetic blocks themselves are easily interfered by external magnetic materials such as mobile phones, headphones, chargers, etc., causing the internal magnetic field strength to change easily, which also affects the startup of the electronic atomizer. How to prevent internal switch corrosion and prevent external magnetic field interference is still a problem that technicians need to solve. Summary of the invention

[0066] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:
[0067] See also Figure 2, which is a pneumatic magnetic sensor device based on anti-false touch according to an embodiment of the present invention, the pneumatic magnetic sensor device includes a housing 100, a pneumatic diaphragm 200, a magnet 300 and a magnetic sensor module 400, the pneumatic diaphragm 200 and the magnetic sensor module 400 are connected to the housing 100, further, the connection can be assembly or fitting, the magnet 300 is arranged on the pneumatic diaphragm 200, the magnetic sensor module 400 includes a magnetic sensor chip and its corresponding logic control chip, the logic control chip is provided with a stack, the stack stores N coordinate threshold intervals, N=1, 2, 3....... Specifically, the N coordinate threshold intervals can be represented as one, two, three, four, etc. The stack belongs to a dynamic memory area, which is used to store multiple coordinate elements, whose elements have corresponding coordinate threshold intervals, and correspond to multiple corresponding magnetic sensing coordinate intervals through the coordinate threshold intervals.
[0068] like Figure 1 As shown, the pneumatic magnetic sensor device based on preventing accidental touch performs the following steps:
[0069] S101, the magnetic sensor chip obtains the magnetic induction intensity, and the magnetic sensor chip performs axis splitting processing according to the stroke change value of the magnetic induction intensity to obtain N magnetic induction coordinate values, N=1, 2, 3...; wherein the stroke change can be expressed as the moving distance of the pneumatic diaphragm 200 when the atomization channel is in a negative pressure state and drives the magnet 300, which is recorded as the moving distance of the magnet 300, and the N magnetic induction coordinate values can be expressed as one-axis magnetic induction coordinate value, two-axis magnetic induction coordinate value, three-axis magnetic induction coordinate value, etc. The magnetic induction intensity is obtained by the magnetic sensor chip, and the magnetic sensor module 400 performs axis splitting processing on the magnetic induction intensity after receiving the coordinate information. The magnetic induction values after axis splitting are divided into the first axis, the second axis, the third axis, etc., and the corresponding magnetic induction coordinate values are obtained to prepare for the detection of the corresponding magnetic induction coordinate values.
[0070] S102, detecting whether N magnetic induction coordinate values correspond one to one to each other within the range of N coordinate threshold intervals; it can be understood that after obtaining the corresponding magnetic induction coordinate values of multiple axes, the magnetic induction coordinate values are checked to confirm whether the magnetic induction coordinate values are within the corresponding coordinate threshold interval, wherein the coordinate threshold interval is a trigger output reference interval.
[0071] S103. If the N magnetic induction coordinate values correspond one to one within the N coordinate threshold intervals, the logic control chip outputs a start signal; when detecting the magnetic induction coordinate values of each axis, only when the magnetic induction coordinate values of all axes are within the corresponding coordinate threshold intervals, the logic control chip uses all acquired magnetic induction coordinate values as high-level values, and then performs logical calculations on all high-level values, outputs a high-level signal, that is, outputs a start signal, and drives the atomization module to start. Specifically, in the absence of external magnetic field interference, as long as there is a suction action, the magnet 300 generally moves vertically relative to the magnetic sensing module 400, and the magnetic induction module detects that the magnetic induction coordinate values of all axes are within the corresponding coordinate threshold intervals, then confirming that there is no magnetic field interference, so that the logic control chip outputs a high-level signal according to the level value corresponding to the magnetic induction coordinate values of all axes. Further, when starting the electronic atomizer, the high level is valid.
[0072] S104. If at least one of the N magnetic induction coordinate values is outside the corresponding coordinate threshold interval, the logic control chip outputs a shutdown signal. It can be understood that when detecting the magnetic induction coordinate value of each axis, under normal conditions, multiple axes are within the corresponding coordinate threshold interval, and it can be confirmed that there is no external magnetic field interference, and the output start signal can be executed. However, as long as the magnetic induction coordinate value of one, two or more axes is outside the corresponding coordinate threshold interval, since the magnet 300 is a magnetic material, it is easily affected by the external magnetism and moves. As long as the external magnetic material approaches the electronic atomizer, the magnetic induction coordinate value of one or more axes will change to a certain extent. The movement of the magnet 300 causes the corresponding magnetic induction coordinate value to exceed the corresponding coordinate threshold interval. The logic control chip uses the current magnetic induction coordinate value as a low level value. In this way, when there is at least one axis of magnetic induction, the magnetic induction coordinate value of the axis is changed to a certain extent. When the magnetic sense coordinate value is outside the corresponding coordinate threshold interval, the logic control chip records the magnetic sense coordinate value of at least one axis as a low level value, and performs logical calculations on the level values corresponding to the magnetic sense coordinate values of all axes, and outputs a shutdown signal, thereby preventing the electronic atomizer from starting automatically. In this way, as long as there are magnetic materials such as mobile phones, headphones, etc. close to the electronic atomizer, there must be interference in the magnetic field, so that the magnetic sense coordinate value of at least one axis is outside the corresponding coordinate threshold interval. When the value of the current axis exceeds the standard interval, it is determined that there is a difference between the value of the current axis and the value of the corresponding standard interval. After logical calculation, the logic control chip does not meet the startup conditions, and then outputs a low level signal, which is not used as a condition for starting the electronic atomizer.
[0073] In this embodiment, the pneumatic magnetic sensing device based on anti-false touch adopts multi-axis magnetic induction coordinates to confirm whether there is interference from external magnetic materials, thereby preventing atomization loss caused by self-start of the electronic atomizer. Specifically, if the multi-axis magnetic induction coordinate values are all within the corresponding coordinate threshold interval range, it means that there is no interference from magnetic materials, and the logic control chip outputs a start signal, and then the electronic atomizer can start normally to work. If one or more of the multi-axis magnetic induction coordinate values are outside the corresponding coordinate threshold interval range, it means that there is interference from magnetic materials. In the case of magnetic material interference, the logic control chip outputs a shutdown signal to prevent the electronic atomizer from self-starting. In this way, when the user puts magnetic materials such as mobile phones, headphones, etc. together with the electronic atomizer, the logic control chip prevents the atomization module of the electronic atomizer from self-starting according to the multi-axis magnetic induction coordinate information. It can be understood that the output start signal corresponds to the normal start-up action of the electronic atomizer. When the electronic atomizer is started, the high level is valid; the output shutdown signal corresponds to the action of preventing the electronic atomizer from starting itself, which is a low-level signal, that is, as long as there is interference from magnetic materials, the magnetic sense coordinate value of at least one axis is not within the corresponding standard range, that is, the magnetic sense component intensity of the axis is different from the magnetic sense component intensity of the axis under the reference state. The logic control chip records the current coordinate value as a low-level value. As long as the low-level value exists, the shutdown signal is output and it is not used as a startup condition.
[0074] In one embodiment, when S103 is executed, the following steps are included: if the magnetic induction intensity travel change value includes the magnetic induction intensity vector of the magnet 300, the N magnetic induction coordinate values correspond one-to-one within the N coordinate threshold intervals, and the logic control chip outputs a start signal. In this embodiment, the magnetic induction intensity of the magnet 300 can be divided into the magnetic induction intensity of multiple sub-axes. Under normal circumstances, the travel change value of the magnetic induction intensity is equal to the sum of the magnetic induction intensity travel change values corresponding to the multiple sub-axes, and there is no magnetic induction vector formed by external force, which means that the magnetic induction coordinate values of all axes correspond one-to-one within the corresponding coordinate threshold intervals. Then, the logic control chip processes the magnetic induction coordinate values of all axes to make them high-level values, thereby serving as a condition for starting the atomization module.
[0075] In one embodiment, after executing S103, the following steps are also included: obtaining the running time value after the output start signal; according to whether the running time value is greater than or equal to the over-discharge protection critical value; if the running time value is greater than or equal to the over-discharge protection critical value, the atomization module stops working. In this embodiment, after the start signal is output, the power supply is powered on to make the electronic atomizer work. In order to prevent the dry burning of the atomization medium caused by long-term atomization, the clock chip of the electronic atomizer will also start to record the running time value during atomization. During atomization, if the working time is too long, there will definitely be power loss, or there will be safety hazards caused by excessive atomization, such as temperature rise and the possibility of accelerated battery loss. Therefore, when the execution time exceeds the allowed execution time threshold, it means that the atomization time is too long. At this time, the control module stops outputting according to the time value to shut down the atomization module, thereby preventing the electronic atomizer from continuing to work, thereby protecting the electronic atomizer from continuing to consume power from its battery or excessive atomization causing dry burning of the atomization medium. Furthermore, the pneumatic magnetic sensor device also includes a counting chip, which is used to count the running time value incrementally. When the count reaches a predetermined value, an overflow signal is generated, which can trigger an interrupt operation, thereby stopping the atomization module from working.
[0076] In a preferred embodiment, the over-discharge protection threshold is 10 seconds.
[0077] In another embodiment, depending on whether the running time value is greater than or equal to the over-discharge protection critical value, the following steps are also included: if the running time value is less than the over-discharge protection critical value, the control module does not perform any processing.
[0078] In one embodiment, when S104 is executed, the following steps are included:
[0079] The magnetic induction intensity travel change value includes the component of the magnetic induction intensity of the magnet 300 and the component of the magnetic induction intensity of the external magnetic field. If at least one of the N magnetic induction coordinate values is outside the corresponding coordinate threshold interval, the logic control chip outputs a shutdown signal. In this embodiment, the magnetic induction intensity of the magnet 300 can be divided into the magnetic induction intensity of multiple sub-axes. Under normal circumstances, the travel change value of the magnetic induction intensity is equal to the sum of the travel change values of the magnetic induction intensity corresponding to the multiple sub-axes, and there is no magnetic induction vector formed by external force, which means that the magnetic induction coordinate values of all axes are one-to-one within the corresponding coordinate threshold interval. If the sum of the stroke change values of the magnetic induction intensity is equal to the sum of the stroke change values of the magnetic induction intensity corresponding to multiple sub-axes and the components of the external magnetic field intensity, it means that the magnet 300 is acted upon by at least one axis, so that the magnetic induction intensity of the axis is outside the corresponding coordinate threshold interval. The logic control chip performs logical calculations on the data according to the magnetic induction intensity of the current axis, and records it as a low-level value, while performing logical calculations on other values within the corresponding coordinate threshold interval, and records them as high-level values. Then the logic control chip performs logical calculations on multiple high-level values and low-level values, such as AND gate calculations. Since one or more axes of the magnet 300 are acted upon by external force, so that the magnetic induction coordinate value of the axis is outside the corresponding coordinate threshold interval, the condition for starting the atomization module is not met. The logic control chip outputs a shutdown signal, i.e., a low-level signal, to prevent the electronic atomizer from starting itself, i.e., interference from external magnetic substances is not a condition for starting the electronic atomizer.
[0080] In one embodiment, after executing S101, the following steps are included:
[0081] Obtaining magnet 300 strength parameters;
[0082] Acquire a magnetic sensing distance parameter, wherein the magnetic sensing distance is the distance between the magnet 300 and the magnetic sensor chip;
[0083] Comparing the strength parameter of the magnet 300 with the magnetic sensing distance parameter to see whether they match;
[0084] If the strength parameter of the magnet 300 matches the magnetic sensing distance parameter, the logic control chip outputs a start signal;
[0085] If the strength parameter of the magnet 300 does not match the magnetic induction distance parameter, obtain N magnetic induction coordinate values;
[0086] If the N magnetic sense coordinate values are within the corresponding preset coordinate threshold range, the logic control chip outputs a start signal;
[0087] If at least one of the N magnetic sensing coordinate values is outside the corresponding preset coordinate threshold range, the logic control chip outputs a shutdown signal.
[0088] In this embodiment, the strength parameter of the magnet 300 is the magnetic induction strength of the magnet itself. The change of the magnetic induction coordinate value read by the magnetic sensor chip is generally related to the moving distance of the magnet 300. When the magnetic induction coordinate value read decreases, it means that the magnet 300 moves away from the magnetic sensor chip until the magnetic induction coordinate value of the multi-axis is within the corresponding coordinate threshold range, so that the logic control chip outputs a high level signal according to the sum of the level values converted from the coordinate value to start normally. In fact, the strength value of the magnet 300 is affected by the external environment such as external temperature, external humidity, etc., so that the pneumatic diaphragm 200 is deformed by the external influence. The magnetic induction intensity and the coordinate data after axis division obtained by the magnetic sensor chip are not fixed, but fluctuate up and down. Therefore, the magnetic strength generally has an upper limit and a lower limit. When the actual strength value of the magnet 300 does not correspond to the magnetic induction distance, the axis division is performed again to obtain the multi-axis strength value of the magnet 300. When the magnetic induction coordinate values corresponding to the multiple axes are within the corresponding preset coordinate threshold interval, the condition for starting the atomization module is met. When at least one of the magnetic induction coordinate values corresponding to the multiple axes is outside the corresponding preset coordinate threshold interval, it means that the magnet 300 has external force in any one or more directions, thereby preventing the electronic atomizer from starting automatically. In this way, the upper and lower limits of the magnet 300 strength set can eliminate the numerical error caused by the interference of non-magnetic materials, thereby ensuring that the electronic atomizer is not started as long as it is confirmed that there is external magnetic field interference.
[0089] In a preferred embodiment, N=3; and,
[0090] The preset coordinate threshold interval includes an X-axis preset coordinate threshold interval, a Y-axis preset coordinate threshold interval and a Z-axis preset coordinate threshold interval;
[0091] The range of the X-axis preset coordinate threshold interval is X1-X2, the range of the Y-axis preset coordinate threshold interval is Y1-Y2, and the range of the Z-axis preset coordinate threshold interval is Z1-Z2.
[0092] Further, the range of the preset coordinate threshold interval of the X-axis is 50-60, the range of the preset coordinate threshold interval of the Y-axis is 50-60, and the range of the preset coordinate threshold interval of the Z-axis is 80-120.
[0093] Furthermore, the strength of the magnet 300 is 800-1000 Gs, and the magnetic sensing distance is 0.3±0.01 mm.
[0094] Among them, the X-axis and the Y-axis are directions in which the magnet 300 extends parallel to the magnetic sensor chip, and the X-axis and the Y-axis are perpendicular to each other, and the Z-axis is a direction in which the magnet 300 extends perpendicular to the magnetic sensor chip. When the electronic atomizer is started, the magnet 300 moves mainly in the Z-axis direction, and the coordinate value changes obtained on the magnetic sensor chip are larger than the coordinate value changes of the X-axis and the Y-axis. Furthermore, the range of the preset coordinate threshold interval of the X-axis is 50-60, the range of the preset coordinate threshold interval of the Y-axis is 50-60, and the range of the preset coordinate threshold interval of the Z-axis is 80-120, wherein the preset coordinate threshold interval represents the coordinate threshold interval when the startup is triggered. For example, in the standby state, the strength of the magnet is 1000Gs, and the XYZ axis read by the magnetic sensor chip is (80, 80, 200). When the magnet 300 is subjected to negative pressure, the pneumatic diaphragm drives the magnet to move away from the magnetic sensor chip. At this time, the XYZ axis value read by the magnetic sensor chip is (60, 60, 100), the values of the three axes all reach the corresponding preset coordinate threshold interval, and then the electronic atomizer is started. However, in fact, when the ambient temperature and humidity change or there is dust adhesion, the magnetic strength will also change accordingly, for example, 900Gs. At this time, when the magnetic sensor chip acquires data in real time, the XYZ axis read is (75, 75, 190). When the magnet 300 is subjected to negative pressure, the pneumatic diaphragm drives the magnet to move away from the magnetic sensor chip. At this time, the XYZ axis value read by the magnetic sensor chip is (55, 55, 90). Similarly, the values of the three axes all reach the corresponding preset coordinate threshold interval, and the electronic atomizer can also be started. In this way, the preset coordinate threshold interval can eliminate false triggering caused by external non-magnetic field interference. In this embodiment, the magnetic field coordinate value of the Z axis read by the magnetic sensor chip before the trigger is 200Gs, and the magnetic field coordinate value of the Z axis read by the magnetic sensor chip during the trigger is 100Gs.
[0095] Of course, in the above-mentioned embodiments, it is not limited to setting the range of the preset coordinate threshold interval of the X-axis to 50-60, the range of the preset coordinate threshold interval of the Y-axis to 50-60, and the range of the preset coordinate threshold interval of the Z-axis to 80-120. The range of the preset coordinate threshold interval of the X-axis can also be set to 300-400, the range of the preset coordinate threshold interval of the Y-axis to 300-400, and the range of the preset coordinate threshold interval of the Z-axis to 2000-2600, etc. The numerical setting of the preset coordinate threshold interval of the corresponding axis, the magnet strength and the magnetic sensing distance, etc., are only used as examples and should not be used as restrictions on the coordinate threshold interval. It should be noted that the specific range of the preset coordinate threshold interval of the X-axis given in the above-mentioned embodiments are all preferred embodiments, but in actual scenarios, if the product structure or function changes, those skilled in the art can make adjustments according to the actual situation, and it is not limited to being unchangeable.
[0096] In one embodiment, when S103 is executed, the following steps are specifically included:
[0097] If the N magnetic induction coordinate values correspond one to one within the N coordinate threshold intervals, the interval matching time value is obtained, and it is detected whether the interval matching time value is less than the startup critical time value; if the interval matching time value is less than the startup critical time value, the logic control chip outputs a shutdown signal.
[0098] It can be understood that the interval matching time value is the start delay time, and the start critical time value is the trigger start threshold. At the moment when the multi-axis magnetic induction coordinate values correspond one-to-one within the corresponding coordinate threshold interval, the timing chip of the electronic atomizer starts to record the start delay time. When the time exceeds the trigger start threshold, as long as the multi-axis magnetic induction coordinate values correspond one-to-one within the corresponding coordinate threshold interval, a high-level signal can be output to trigger the control of the atomization module to start; if the start delay time is lower than the trigger start threshold, the atomization module will not be triggered to start. By delaying the start, the vibration caused by the electronic atomizer can be eliminated. The pneumatic diaphragm 200 vibrates. Specifically, the magnetic sensor chip acquires the magnetic coordinate values of multiple axes in real time. When it detects that the magnetic coordinate values of multiple axes are all within the corresponding coordinate threshold range, the timing chip starts to count up. Subsequently, before the start delay time reaches the trigger start threshold, the magnetic sensor chip detects that the magnetic coordinate values of multiple axes are all outside the corresponding coordinate threshold range. It is then determined that the movement of the magnet 300 is caused by the vibration of the pneumatic diaphragm 200, and the logic control chip outputs a shutdown signal, which is not used as a start condition. This prevents the electronic atomizer from self-starting due to the vibration of the start diaphragm.
[0099] In another embodiment, the detection of whether the interval matching time is less than the critical start time also includes: if the interval matching time value is greater than or equal to the critical start time value, the logic control chip outputs a start signal. When it is detected that the magnetic sense coordinate values of the multiple axes are all within the corresponding coordinate threshold interval, the timing chip starts to count up, and then after the start delay time reaches the trigger start threshold, the magnetic sensor chip detects that the magnetic sense coordinate values of the multiple axes are still within the corresponding coordinate threshold interval, and the magnetic sense coordinate values of the multiple axes are processed as a high level, and then the logic control chip outputs a start signal to control the start of the atomization module, thereby achieving the effect of delayed start, preventing the electronic atomizer from being falsely triggered at the moment of non-magnetic field interference, such as vibration of the pneumatic diaphragm 200.
[0100] In another embodiment, the startup critical time value is 50 ms, that is, the trigger startup time threshold is 50 ms.
[0101] In one of the embodiments, the pneumatic magnetic sensing device based on anti-false touch also performs the following steps: the magnetic sensing chip periodically obtains N magnetic induction coordinate values, and uses the current magnetic induction coordinate value as the magnetic induction threshold. It can be understood that since the strength of the magnet changes due to the interference factors of non-magnetic field materials such as changes in external temperature, changes in external humidity, and dust content, these factors make the pneumatic diaphragm tend to deform, so the multi-axis magnetic induction coordinate values obtained by the magnetic sensing chip have certain fluctuations. Therefore, the magnetic sensing chip periodically reads the N-axis magnetic induction coordinate value, regardless of whether the magnetic induction coordinate value of the N axes is equal to the corresponding magnetic induction threshold, every other cycle, the magnetic induction coordinate value of the current axis is updated and used as the new magnetic induction threshold, thereby eliminating the false triggering caused by the deformation of the pneumatic diaphragm caused by non-magnetic field interference; therefore, no matter in high temperature, low temperature or cold environment, as long as there is no external magnetic field interference, the electronic atomizer can be started normally.
[0102] In one embodiment, the period for obtaining the N magnetic induction coordinate values is 1 second.
[0103] In one embodiment, N=3, that is, the magnetic induction coordinate values are divided into X-axis magnetic induction coordinate values, Y-axis magnetic induction coordinate values and Z-axis magnetic induction coordinate values; and,
[0104] When S102 is executed, the following steps are specifically included:
[0105] Get the X-axis magnetic coordinate value;
[0106] Check whether the X-axis magnetic sense coordinate value corresponds to the X-axis coordinate threshold range;
[0107] If the X-axis magnetic sense coordinate value corresponds to a value outside the X-axis coordinate threshold interval, the logic control chip outputs a shutdown signal;
[0108] If the X-axis magnetic induction coordinate value is within the X-axis coordinate threshold range, obtain the Y-axis magnetic induction coordinate value;
[0109] Detect whether the Y-axis magnetic sense coordinate value corresponds to the Y-axis coordinate threshold range;
[0110] If the Y-axis magnetic sense coordinate value corresponds to a value outside the Y-axis coordinate threshold interval, the logic control chip outputs a shutdown signal;
[0111] If the Y-axis magnetic sense coordinate value is within the Y-axis coordinate threshold range, obtain the Z-axis magnetic sense coordinate value;
[0112] Check whether the Z-axis magnetic sense coordinate value corresponds to the Z-axis coordinate threshold range;
[0113] If the Z-axis magnetic sense coordinate value corresponds to a value outside the Z-axis coordinate threshold interval, the logic control chip outputs a shutdown signal;
[0114] If the Z-axis magnetic sense coordinate value corresponds to the Z-axis coordinate threshold interval, the logic control chip outputs a start signal.
[0115] In this embodiment, the magnetic sensor chip acquires the magnetic induction intensity in real time, and divides the value into X-axis magnetic induction coordinate value, Y-axis magnetic induction coordinate value and Z-axis magnetic induction coordinate value. In this way, the X-axis magnetic induction coordinate value, Y-axis magnetic induction coordinate value and Z-axis magnetic induction coordinate value obtained after the axis division are confirmed whether they are respectively within the X-axis coordinate threshold interval range, the Y-axis coordinate threshold interval range and the Z-axis coordinate threshold interval range. Specifically, the magnetic sensor chip obtains the magnetic induction intensity in real time, and then divides the axis according to the stroke change value of the magnetic induction intensity to obtain the magnetic induction data of the three axes. The X-axis magnetic induction coordinate value is read first, and the X-axis magnetic induction coordinate value is compared to see whether it is within the corresponding coordinate threshold interval. If it is within the corresponding coordinate threshold interval, the logic control chip records it as a high level value according to the X-axis numerical value. The magnetic sensor chip continues to read the Y-axis magnetic induction coordinate value to detect whether the Y-axis magnetic induction coordinate value is within the corresponding coordinate threshold interval. If it is within the corresponding coordinate threshold interval, the logic control chip records it as a high level value according to the Y-axis numerical value. The magnetic sensor chip continues to read the Z-axis magnetic induction coordinate value to detect whether the Z-axis magnetic induction coordinate value is within the corresponding coordinate threshold interval. If it is within the corresponding coordinate threshold interval, the logic control chip records it as a high level value according to the Z-axis numerical value. Subsequently, the logic control chip performs logical calculations on the three high level values to confirm the output of a high level signal so that the atomization module can start normally. As long as it is detected that the magnetic induction coordinate value of at least one axis is outside the coordinate threshold interval of the corresponding axis, the logic control chip records it as a low-level value according to the corresponding numerical value, and performs logic calculation after level processing on the numerical values of the three axes. As long as there is at least one low-level value, a low-level signal is output to prevent the electronic atomizer from starting automatically. Specifically, when detecting the X-axis magnetic induction coordinate value, if the value is outside the X-axis coordinate threshold interval, the logic control chip records it as a low-level value according to the X-axis numerical value; when the detection confirms that the X-axis magnetic induction coordinate value is within the X-axis coordinate threshold interval If the magnetic sense coordinate value of the X-axis is within the range of the X-axis coordinate threshold value, but the Y-axis magnetic sense coordinate value is detected to be outside the Y-axis coordinate threshold range, the logic control chip records it as a high level value according to the X-axis value, and records it as a low level value according to the Y-axis value; when the detection confirms that the X-axis magnetic sense coordinate value is within the X-axis coordinate threshold range, and the detection confirms that the Y-axis magnetic sense coordinate value is within the Y-axis coordinate threshold range, but the Z-axis magnetic sense coordinate value is detected to be outside the Z-axis coordinate threshold range, the logic control chip records it as a high level value according to the X-axis value and the Y-axis value, and records it as a low level value according to the Z-axis value. In this way, when the logic control chip sequentially obtains the level values corresponding to the values of the X-axis, Y-axis, and Z-axis, as long as there is a low level value, the logic control chip outputs a low level signal, that is, outputs a shutdown signal, so that the electronic atomizer will not be disturbed by the proximity of magnetic materials, thereby preventing the electronic atomizer from self-starting. Even if the user puts magnetic materials such as Bluetooth headsets, power banks, etc. together with the electronic atomizer, the electronic atomizer will not start automatically, thereby preventing the dry burning of the atomized medium caused by self-starting.
[0116] When the electronic atomizer is in standby mode, as long as the magnetic sense coordinate value after axis division is outside the corresponding coordinate threshold interval, a shutdown signal is output to prevent the electronic atomizer from starting automatically. Otherwise, the electronic atomizer is started normally. However, when the electronic atomizer is in working mode, if magnetic material approaches the electronic atomizer, the magnetic sense coordinate value of at least one axis will be outside the corresponding interval, so that the logic control chip outputs a low-level signal to stop the atomization module from working, which causes the electronic atomizer to stop suddenly, greatly reducing the user experience of the electronic atomizer.
[0117] Therefore, in one embodiment, the magnetic sensing module 400 also includes a dynamic magnetic sensing chip and its corresponding dynamic logic control chip, the dynamic logic control chip is provided with a dynamic stack, and the dynamic stack stores N dynamic coordinate threshold intervals, N ≥ 1. Specifically, the N coordinate threshold intervals can be represented as one, two, three, four, etc. The dynamic stack, like the above-mentioned stack, belongs to the memory area. The dynamic stack is used to store multiple coordinate elements when the electronic atomizer is working, and its elements have corresponding coordinate intervals, and the coordinate intervals correspond to multiple corresponding magnetic sensing coordinate intervals.
[0118] In one embodiment, after executing S103, the following steps are also included:
[0119] S1031, detecting whether the N magnetic induction coordinate values correspond one to one to each other within the range of the N dynamic coordinate threshold values;
[0120] S1032, if the N magnetic induction coordinate values are within the N dynamic coordinate threshold intervals, the dynamic logic control chip outputs a positive stop signal;
[0121] S1033: If at least one of the N magnetic induction coordinate values is outside the corresponding dynamic coordinate threshold interval, the dynamic logic control chip outputs a blocking signal.
[0122] It can be understood that the dynamic coordinate threshold interval range is expressed as the coordinate threshold interval range of the electronic atomizer when it is working. The blocking signal is a signal to prevent the electronic atomizer from being disturbed by the external magnetic field and causing power failure. The positive stop signal is a signal that can cause the electronic atomizer to be powered off under human action. When the electronic atomizer is working, the magnetic sensing chip and the corresponding logic control chip are disabled and replaced by the dynamic magnetic sensing chip to obtain the magnetic sense coordinate values of the N axes when the electronic atomizer is working in real time. The magnetic sensing module then checks the value to confirm whether the magnetic sense coordinate value is within the corresponding dynamic coordinate threshold interval range. When the N magnetic induction coordinate values correspond one by one within the N dynamic coordinate threshold ranges, that is, the magnetic induction coordinates of the N axes are within the corresponding dynamic coordinate threshold ranges, it can be confirmed that there is no external magnetic field interference and no signal shielding processing is required. In this way, when the electronic atomizer is finished using, it can enter the standby mode normally; when at least one of the N magnetic induction coordinate values is outside the corresponding dynamic coordinate threshold range, that is, one or more of the magnetic induction coordinates of the N axes are outside the corresponding dynamic coordinate threshold range, it can be confirmed that there is external magnetic field interference, so that the corresponding dynamic coordinate threshold range is adjusted so that the magnetic induction coordinate value of the corresponding axis falls within the corresponding dynamic coordinate threshold range, thereby maintaining the normal operation of the electronic atomization device and preventing the electronic atomizer from stopping due to external magnetic field interference during operation.
[0123] In a preferred embodiment, N=3; and when S1031 is executed, the following steps are specifically included:
[0124] Get the X-axis magnetic coordinate value;
[0125] Check whether the X-axis magnetic sense coordinate value corresponds to the X-axis dynamic coordinate threshold range;
[0126] If the X-axis magnetic induction coordinate value corresponds to the X-axis dynamic coordinate threshold interval, the dynamic logic control chip outputs a stop signal;
[0127] If the X-axis magnetic induction coordinate value is within the X-axis dynamic coordinate threshold interval, obtain the Y-axis magnetic induction coordinate value;
[0128] Check whether the Y-axis magnetic sense coordinate value corresponds to the Y-axis dynamic coordinate threshold range;
[0129] If the Y-axis magnetic sense coordinate value corresponds to the Y-axis dynamic coordinate threshold value range, the dynamic logic control chip outputs a stop signal;
[0130] If the Y-axis magnetic sense coordinate value corresponds to the Y-axis dynamic coordinate threshold interval, the Z-axis magnetic sense coordinate value is obtained;
[0131] Check whether the Z-axis magnetic sense coordinate value corresponds to the Z-axis dynamic coordinate threshold range;
[0132] If the Z-axis magnetic sense coordinate value corresponds to the range outside the Z-axis dynamic coordinate threshold value interval, the dynamic logic control chip outputs a stop signal;
[0133] If the Z-axis magnetic sense coordinate value corresponds to the Z-axis dynamic coordinate threshold interval, the dynamic logic control chip outputs a positive stop signal.
[0134] It can be understood that the dynamic coordinate threshold interval range is equivalent to the coordinate threshold interval range mentioned in S102. Specifically, the N coordinate threshold intervals can be expressed as one, two, three, four, etc. The dynamic stack, like the above-mentioned stack, belongs to the memory area. The dynamic stack is used to store multiple coordinate elements when the electronic atomizer is working. Its elements have corresponding coordinate intervals, and the coordinate intervals correspond to multiple corresponding magnetic induction coordinate intervals. A preferred embodiment is selected here, that is, N=3. It can be understood that the blocking signal is a high-level signal that prevents the electronic atomizer from being disturbed by the external magnetic field and causing power failure, and the positive stop signal is a low-level signal that can cause the electronic atomizer to be powered off under human action. When the electronic atomizer is in working state, the magnetic induction chip stops reading and the corresponding logic control chip is disabled. The dynamic magnetic sensor chip obtains the magnetic induction intensity in real time, and then divides the axis according to the obtained magnetic induction intensity stroke change value to obtain the magnetic induction data of the three axes. The X-axis magnetic induction coordinate value is read first, and the X-axis magnetic induction coordinate value is compared to see whether it is within the corresponding dynamic coordinate threshold range. If it is within the corresponding dynamic coordinate threshold range, the dynamic logic control chip records it as a high level value according to the X-axis value. The dynamic magnetic sensor chip continues to read the Y-axis magnetic induction coordinate value to detect whether the Y-axis magnetic induction coordinate value is within the corresponding dynamic coordinate threshold range. If it is within the corresponding dynamic coordinate threshold range, the dynamic logic control chip records it as a high level value according to the X-axis value. Within the threshold range, the dynamic logic control chip records it as a high level value according to the Y-axis numerical value, and the dynamic magnetic sensor chip continues to read the Z-axis magnetic sense coordinate value to detect whether the Z-axis magnetic sense coordinate value is within the corresponding dynamic coordinate threshold range. If it is within the corresponding dynamic coordinate threshold range, the dynamic logic control chip records it as a high level value according to the Z-axis numerical value. Then the dynamic logic control chip performs logical calculations on the three high level values to confirm that the internal magnet 300 is not interfered by the external magnetic field when the electronic atomizer is working, and outputs a low level signal. In this way, as long as the magnet 300 returns to its initial position, the atomization module can stop normally, so that the electronic atomizer enters the standby mode normally.As long as it is detected that the magnetic induction coordinate value of at least one axis is outside the dynamic coordinate threshold interval range of the corresponding axis, the logic control chip records it as a low level value according to the corresponding numerical value, and performs logic calculation after level processing on the numerical values of the three axes. As long as there is at least one low level value, a high level signal is output to prevent the electronic atomizer from being disturbed by the external magnetic field during operation and causing abnormal atomization or even stopping working. Specifically, when detecting the magnetic induction coordinate value of the X-axis, if the value is outside the dynamic coordinate threshold interval range of the X-axis, the dynamic logic control chip records it as a low level value according to the numerical value of the X-axis; when the detection confirms that the magnetic induction coordinate value of the X-axis is within the X-axis dynamic coordinate threshold interval range, the dynamic logic control chip records it as a low level value according to the numerical value of the X-axis. When the X-axis magnetic induction coordinate value is within the dynamic coordinate threshold range of the X-axis, but the Y-axis magnetic induction coordinate value is detected to be outside the dynamic coordinate threshold range of the Y-axis, the dynamic logic control chip records it as a high level value according to the numerical situation of the X-axis, and records it as a low level value according to the numerical situation of the Y-axis; when the detection confirms that the X-axis magnetic induction coordinate value is within the dynamic coordinate threshold range of the X-axis, and the detection confirms that the Y-axis magnetic induction coordinate value is within the dynamic coordinate threshold range of the Y-axis, but the Z-axis magnetic induction coordinate value is detected to be outside the dynamic coordinate threshold range of the Z-axis, the dynamic logic control chip records it as a high level value according to the numerical situation of the X-axis and the numerical situation of the Y-axis, and records it as a low level value according to the numerical situation of the Z-axis. In this way, the dynamic logic control chip sequentially obtains the level values corresponding to the numerical values of the X-axis, Y-axis and Z-axis. As long as there is a low level value, it can be confirmed that the magnet 300 has external magnetic field interference in at least one axis. The dynamic logic control chip outputs a high level signal through logical calculation, so that the dynamic magnetic sensor chip adjusts the corresponding dynamic coordinate threshold interval according to the situation of the corresponding axis, so that the magnetic sense coordinate value of the corresponding axis is within the adjusted dynamic coordinate threshold interval to maintain the normal operation of the electronic atomizer, that is, the magnetic field interference from the corresponding axis is shielded. For example, when the X-axis magnetic sense coordinate value is outside the X-axis dynamic coordinate threshold interval, the X-axis dynamic coordinate threshold interval is adjusted so that the X-axis magnetic sense coordinate value is within the adjusted X-axis dynamic coordinate threshold interval, so as to have the effect of shielding the external magnetic field interference signal from the X-axis. When the magnetic sense coordinate values of the three axes are all within the corresponding dynamic coordinate threshold interval, there is no need to adjust the corresponding dynamic coordinate threshold interval. During use, as long as the magnet 300 returns to its initial position, the atomization module can be stopped normally, so that the electronic atomizer enters the standby mode normally. At this time, the dynamic magnetic sensing chip and its corresponding dynamic logic control chip are disabled and replaced by the magnetic sensing chip and its corresponding logic control chip. In this way, whether the electronic atomizer is in standby mode or working mode, it can be ensured that it is not affected by the external magnetic field and changes its state, that is, the external magnetic field interference signal is shielded to ensure that the electronic atomizer can be started and shut down normally. Furthermore, the dynamic logic control chip uses NAND gate logic calculation.
[0135] In another embodiment, when S102 is executed, the following steps are specifically included:
[0136] Get the X-axis magnetic coordinate value;
[0137] Check whether the X-axis magnetic sense coordinate value corresponds to the X-axis static coordinate threshold range;
[0138] If the X-axis magnetic sense coordinate value corresponds to the X-axis static coordinate threshold value range, the logic control chip outputs a shutdown signal;
[0139] If the X-axis magnetic induction coordinate value is within the X-axis static coordinate threshold range, obtain the Y-axis magnetic induction coordinate value;
[0140] Check whether the Y-axis magnetic sense coordinate value corresponds to the Y-axis static coordinate threshold range;
[0141] If the Y-axis magnetic sense coordinate value corresponds to a value outside the Y-axis static coordinate threshold interval, the logic control chip outputs a shutdown signal;
[0142] If the Y-axis magnetic sense coordinate value is within the Y-axis static coordinate threshold range, obtain the Z-axis magnetic sense coordinate value;
[0143] Check whether the Z-axis magnetic sense coordinate value corresponds to the Z-axis static coordinate threshold range;
[0144] If the Z-axis magnetic sense coordinate value corresponds to a value outside the Z-axis static coordinate threshold interval, the logic control chip outputs a shutdown signal;
[0145] If the Z-axis magnetic sense coordinate value corresponds to the Z-axis static coordinate threshold interval, the logic control chip outputs a start signal.
[0146] In this embodiment, the static coordinate threshold interval range is the coordinate threshold interval range when the electronic atomizer is in standby mode. Specifically, when the electronic atomizer is in standby mode, the magnetic sensor chip acquires the magnetic induction intensity in real time, and divides the axis according to the change value of the magnetic induction intensity stroke to obtain the magnetic induction data of the three axes. The X-axis magnetic induction coordinate value is read first, and the X-axis magnetic induction coordinate value is compared to see whether it is within the corresponding static coordinate threshold interval. If it is within the corresponding static coordinate threshold interval, the logic control chip records it as a high level value according to the X-axis numerical value. The magnetic sensor chip continues to read the Y-axis magnetic induction coordinate value to detect whether the Y-axis magnetic induction coordinate value is within the corresponding static coordinate threshold interval. If it is within the corresponding static coordinate threshold interval, the logic control chip records it as a high level value according to the Y-axis numerical value. The magnetic sensor chip continues to read the Z-axis magnetic induction coordinate value to detect whether the Z-axis magnetic induction coordinate value is within the corresponding static coordinate threshold interval. If it is within the corresponding static coordinate threshold interval, the logic control chip records it as a high level value according to the Z-axis numerical value. Subsequently, the logic control chip performs logical calculations on the three high level values and outputs a high level signal, so that the atomization module has the conditions for normal startup. As long as there is no external magnetic field interference, the electronic atomizer can be started normally. As long as it is detected that the magnetic induction coordinate value of at least one axis is outside the static coordinate threshold interval of the corresponding axis, the logic control chip records it as a low-level value according to the corresponding numerical value, and performs logic calculation after level processing on the numerical values of the three axes. As long as there is at least one low-level value, a low-level signal is output to prevent the electronic atomizer from starting automatically. Specifically, when detecting the magnetic induction coordinate value of the X-axis, if the value is outside the static coordinate threshold interval of the X-axis, the logic control chip records it as a low-level value according to the numerical value of the X-axis; when the detection confirms that the magnetic induction coordinate value of the X-axis is within the static coordinate threshold interval of the X-axis , but it is detected that the Y-axis magnetic induction coordinate value is outside the Y-axis static coordinate threshold interval, the logic control chip records it as a high level value according to the numerical value of the X-axis, and records it as a low level value according to the numerical value of the Y-axis; when the detection confirms that the X-axis magnetic induction coordinate value is within the X-axis static coordinate threshold interval, and the detection confirms that the Y-axis magnetic induction coordinate value is within the Y-axis static coordinate threshold interval, but it is detected that the Z-axis magnetic induction coordinate value is outside the Z-axis static coordinate threshold interval, the logic control chip records it as a high level value according to the numerical value of the X-axis and the numerical value of the Y-axis, and records it as a low level value according to the numerical value of the Z-axis. In this way, the logic control chip sequentially obtains the level values corresponding to the values of the X-axis, Y-axis and Z-axis. As long as there is a low level value, a low level signal is output, so that the atomization module does not have the conditions for starting, and the electronic atomizer will not be started under human action. Even if there is external magnetic field interference such as headphones, mobile phones, etc. close to the electronic atomizer, at least one of the X-axis magnetic induction coordinate value, the Y-axis magnetic induction coordinate value and the Z-axis magnetic induction coordinate value is outside the corresponding static coordinate threshold interval, so that the atomization module does not have the conditions for starting, thereby preventing the electronic atomizer from starting by itself.Furthermore, the logic control chip adopts AND gate logic calculation.
[0147] At the same time, this embodiment adopts a three-axis static coordinate threshold range. Usually, when the electronic atomizer is in standby mode, the magnetic sensor chip periodically reads the X-axis magnetic induction coordinate value, the Y-axis magnetic induction coordinate value and the Z-axis magnetic induction coordinate value. Since the strength of the magnet 300 is also affected by the external temperature, external humidity, dust, etc., the pneumatic diaphragm 200 is deformed, resulting in changes in the strength of the magnet. The X-axis magnetic induction coordinate value, the Y-axis magnetic induction coordinate value and the Z-axis magnetic induction coordinate value of the magnet 300 are not fixed. Therefore, the magnetic sensor chip continuously reads the current X-axis magnetic induction coordinate value, the Y-axis magnetic induction coordinate value and the Z-axis magnetic induction coordinate value as a judgment standard, and the X-axis magnetic induction coordinate value, the Y-axis magnetic induction coordinate value and the Z-axis magnetic induction coordinate value of the magnet 300 are always within the corresponding static coordinate threshold range, thereby eliminating false triggering caused by deformation of the pneumatic diaphragm 200 due to changes in ambient temperature, etc. Therefore, only when there is external magnetic field interference, that is, there is at least one axial magnetic field coordinate value outside the corresponding static coordinate threshold interval, the atomization module will not have normal starting conditions and the electronic atomizer will not start. Only under conditions of non-magnetic field interference, whether it is temperature changes or humidity changes, etc., the atomization module has normal starting conditions, and as long as the magnet 300 moves up and down, the atomization module can be triggered to start.
[0148] Furthermore, the reading cycle is 1 second. That is, the X-axis magnetic induction coordinate value, the Y-axis magnetic induction coordinate value, and the Z-axis magnetic induction coordinate value are read every 1 second to update the current X-axis magnetic induction coordinate value, the Y-axis magnetic induction coordinate value, and the Z-axis magnetic induction coordinate value in real time.
[0149] Furthermore, when the atomization channel is in a negative pressure state, the magnet moves away from the magnetic sensor module, and the X-axis magnetic induction coordinate value, the Y-axis magnetic induction coordinate value and the Z-axis magnetic induction coordinate value change from the corresponding static coordinate threshold range to the corresponding dynamic coordinate threshold range, then the electronic atomizer is triggered to start normally. When the magnetic induction coordinate values of one or more axes are outside the corresponding dynamic coordinate threshold range, it indicates that there is magnetic field interference, which is not a condition for triggering the start of the electronic atomizer.
[0150] It should be noted that the magnetic induction coordinate values of the X-axis, Y-axis and Z-axis mentioned in the above embodiments are solutions when three axes are adopted, which are preferred specific embodiments. Of course, this solution can adopt two-axis, four-axis, five-axis, six-axis and other solutions to determine whether the magnetic induction coordinate value of the axis is within the corresponding coordinate threshold interval range. The steps adopted in the corresponding specific embodiments are similar, and the specific embodiments and effects when two-axis, four-axis, five-axis, six-axis and other solutions are adopted will not be described here.
[0151] The present disclosure also provides an electronic atomizer containing a pneumatic magnetic sensor device based on anti-accidental touch, including a control module, an atomization module connected to the control module, and the pneumatic magnetic sensor device based on anti-accidental touch as described in any of the above embodiments, the pneumatic diaphragm and the magnet are located on the air inlet of the electronic atomizer, the logic control chip is connected to the control module, and the control module receives and responds to the start signal to control the start of the atomization module. It can be understood that when the N magnetic induction coordinate values correspond one by one within the N coordinate threshold intervals, it indicates that there is no external magnetic field interference. The logic control chip performs level value processing according to the corresponding axis, and then outputs a start signal according to the sum of all level values. After receiving the start signal, the control module drives the atomization module to start. When at least one of the N magnetic induction coordinate values is outside the corresponding coordinate threshold interval, it indicates that there is external magnetic field interference. The logic control chip performs level value processing according to the corresponding axis, wherein the magnetic induction coordinate value of the corresponding axis with interference is recorded as a low level value by the logic control chip, and then outputs a shutdown signal according to the sum of all level values. The control module does not process the signal after receiving it, and thus does not use it as a condition for starting the atomization module.
[0152] Compared with the prior art, the present invention has the following advantages, including but not limited to:
[0153] The above-mentioned pneumatic magnetic sensing device based on anti-false touch uses multi-axis magnetic induction coordinates to confirm whether there is interference from external magnetic materials, thereby preventing atomization loss caused by the self-start of the electronic atomizer. Specifically, if the multi-axis magnetic induction coordinate values are all within the corresponding coordinate threshold interval range, it means that there is no interference from magnetic materials, and the logic control chip outputs a start signal, and then the electronic atomizer can start normally to work. If one or more of the multi-axis magnetic induction coordinate values are outside the corresponding coordinate threshold interval range, it means that there is interference from magnetic materials. In the case of magnetic material interference, the logic control chip outputs a shutdown signal to prevent the electronic atomizer from self-starting. In this way, when the user puts magnetic materials such as mobile phones, headphones, etc. together with the electronic atomizer, the logic control chip prevents the atomization module of the electronic atomizer from self-starting according to the multi-axis magnetic induction coordinate information.
