Detailed Description

In order to make the technical problems, technical schemes and beneficial effects to be solved more clear, the invention is further described in detail below with reference to the embodiments and the accompanying drawings. It should be understood that the detailed description of the embodiments in this section is intended to illustrate the invention, and is not intended to limit the invention.

Detailed description of the preferred embodiments

As shown in fig. 1, fig. 2, and fig. 3, the embodiment of the invention provides an environment schematic diagram of an electronic cigarette implementation. The electronic cigarette 100 includes a housing 110, and an atomizing assembly 120 (corresponding to a smoke generating device) disposed within the housing 110 for generating smoke, a power supply 130, a chamber 140 for storing a smoke generating substance, an airflow channel 150, a flow meter 160 for detecting a flow rate of the gas, a control circuit 170, and a smoke sensor 180 for detecting a concentration of the smoke. The housing 110 is provided with a window 111, a suction end 112, a bottom end 113 and a key switch 114, and a user can observe the condition in the cavity 140 through the window 111. The airflow channel 150 includes an airflow inlet 151 and an airflow outlet 152, wherein the airflow inlet 151 is disposed at the bottom end 113 and the airflow outlet 152 is disposed at the suction end 112. The atomizing assembly 120 is configured to atomize the smoking material to produce a smoke, which ultimately flows out through the airflow channel 150 for inhalation by a user. The flowmeter 160 and the air pressure switch 161 are both disposed on the housing 110, the flowmeter 160 is disposed near the air inlet 151 to detect the flow rate of the air flowing from the air inlet 151, and in the air flow direction, the flowmeter 160 is disposed below the air pressure switch 161 (also referred to as microphone in the electronic cigarette field), and the power supply 130 is preferably a rechargeable battery. In this embodiment, the smoke generating material is selected from common tobacco tar (in the prior art, tobacco and tobacco paste) as an example, as shown in fig. 4, the atomization component 120 includes an oil absorbing member 121 and a heating wire 122, the oil absorbing member 121 absorbs the tobacco tar stored in the cavity 140 through the through hole 141, and the heating wire 122 contacts the oil absorbing member 121 to heat the tobacco tar absorbed by the oil absorbing member 121 to atomize the tobacco tar into smoke. The tact switch 114 is used for controlling whether the electronic cigarette 100 is powered on or not, so as to give out a signal, and the control circuit 170 controls the related electronic components to operate. In other embodiments, the atomizing assembly 120 may alternatively be a high frequency vibration generator, under suitable circumstances of implementation, as is known in the art.

As shown in fig. 4 and 5, the airflow channel 150 includes a designated area 190, and the designated area 190 is closer to the end of the airflow than the atomizing assembly 120 in the airflow direction. The designated area 190 is independent of the main path of the airflow channel 150 such that there is a bend between the designated area 190 and the main path of the airflow channel 150 (as indicated by smoke inlet 191 and smoke outlet 192). The purpose of the bend is to separate the detection space and also to make the air flow more gentle. The specified area 190 is communicated with the airflow channel 150 through the smoke inlet 191 and the smoke outlet 192, and smoke generated by the atomization of the tobacco tar by the atomization component 120 flows out of the airflow outlet 152 after passing through the specified area 190. In this embodiment, the smoke sensor 180 is disposed in the designated area 190 to detect the smoke concentration in the designated area 190, and the smoke inlet 191 and the smoke outlet 192 are disposed on the sides of the designated area 190 and near the two ends, respectively. The smoke sensor 180 is a gas sensor that detects the density of air in a designated area 190 (measuring chamber), or the mass of an active ingredient contained in a unit volume of air (e.g., nicotine in tobacco tar), typically by physical or chemical means. The smoke sensor 180 includes a light emitting unit 181 and a light receiving unit 182, and the light emitting unit 181 and the light receiving unit 182 are provided in the specified area 190 in opposition (may be provided in opposition to the side surface of the specified area 190 or may be provided separately on both end surfaces of the specified area 190). Specifically, the light emitting unit 181 emits photons, the light receiving unit 182 gives corresponding electrical signals according to the intensity of the received photons, and the control circuit 170 calculates the concentration of smoke in the designated area 190 according to the different electrical signals transmitted from the light receiving unit 182. For example, the designated area 190 is in normal air, and the light receiving unit 182 receives an electric signal corresponding to the intensity of the photon emitted from the light emitting unit 181; as the smoke concentration in the measurement chamber changes, the photon intensity received by the light receiving unit 182 changes, and thus the given electrical signal changes, and the control circuit 170 calculates the smoke concentration at different times in the designated area 190 from the different electrical signals.

Preferably, the light emitting unit 181 emits light of a short wavelength. The light emitting unit 181 in this embodiment emits ultraviolet light, and the wavelength range of the ultraviolet light is preferably 400-405nm. To prevent interference of external light, the designated area 190 is preferably made of a black material (or the inner surface of the designated area 190 is coated in black). This is because the black absorbs photons and prevents reflection of photons. In this way, the consistency (also referred to as accuracy) of the detection data of the smoke sensor 180 can be improved when setting the correction value.

In other embodiments, the inner surface of the designated area 190 may be provided as a flat plane or as a mirror surface. The purpose of the flat plane or mirror is to prevent photons emitted by the light emitting unit 181 from being lost in the designated area 190. Therefore, when the correction value is not set, the accuracy of the detection data of the smoke sensor 180 can be improved. In practice, polishing treatment may be performed on the inner surface of the designated area 190 to improve the flatness and smoothness of the inner surface of the designated area 190, and finally achieve the mirror effect.

In other embodiments, the flow meter 160 may be modified to be located at or near the airflow outlet 152, within the airflow channel 150, or within the designated area 190.

As shown in fig. 4, the control circuit 170 includes a timer 171, a memory 172, a processor 173 and an alarm element 174, and the control circuit 170 can control the operation of each electronic component, where the timer 171 is used to record the operation states of the smoke sensor 180 and the flowmeter 160 at different moments, so as to obtain corresponding concentration data and flow data at different times. The memory 172 stores a plurality of instruction codes including concentration data, flow rate data, a set value (e.g., an index of the inhalation amount of nicotine), a predetermined value, a preset concentration (an instantaneous concentration maximum value that the components of various atomized substances cannot exceed), a set time (e.g., set to 2 hours), etc. The processor 173 can call instruction code stored in the memory 172 to perform the following operations: a. judging whether the sucking end 112 in the electronic cigarette 100 is sucked or not, and if so, executing subsequent operations; b. the smoke sensor 180 detects the concentration of smoke passing through the designated area 190, and obtains concentration data of the electronic cigarette 100 at the time of suction; meanwhile, the flowmeter 160 detects the flow rate of the gas passing through the airflow channel 150 in the electronic cigarette 100, and obtains flow rate data under the pumping time; c. the processor 173 counts the outflow amount of the smoke flowing out of the electronic cigarette 100 (the airflow outlet 152) under the pumping time according to the detected concentration data and flow data (when the timer 171 is not set, the smoke sensor 180 and the flowmeter 160 need to be controlled to work simultaneously to improve the accuracy of the statistics); d. when the outflow reaches the set point, the electronic cigarette 100 is controlled not to flow smoke (in other embodiments, it may alternatively be configured to alert the user to health by alerting the user via the alert element 174).

Specifically, in operation a, the scheme of judging whether the electronic cigarette 100 is smoked is: since the instantaneous air pressure in the air flow path 150 becomes small when the user sucks the electronic cigarette 100, it is detected whether the air pressure in the air flow path 150 becomes small through the air pressure switch 161, and if so, the electronic cigarette 100 can be considered to be sucked. In other embodiments, the scheme for determining whether the electronic cigarette 100 is smoked may be replaced with: by providing a contact sensor (such as a contact switch) at the suction end 112, it is detected whether the human body contacts the suction end 112 of the electronic cigarette 100 at multiple points; or the control circuit 170 detects whether a switch (e.g., the key switch 114) that controls the electronic cigarette 100 to produce smoke is touched.

In operation b, the method for detecting the flow rate of the gas passing through the gas flow channel 150 in the electronic cigarette 100 is: the flow rate of the gas entering the gas flow channel 150 from the gas flow inlet 151 is detected by the flow meter 160, and is thus actually derived, that is, the flow rate of the gas passing through the designated area 190. In other embodiments, the method of detecting the flow of gas through the airflow channel 150 in the e-cigarette 100 may also be modified as follows: a flow meter is provided at the smoke inlet 191 or the smoke outlet 192 of the designated area 190 to detect the flow rate of the gas passing through the designated area 190; or a flow meter may be provided at the gas flow outlet 152 to detect the flow rate of the gas flowing out of the gas flow channel 150.

In operation d, the control scheme of the electronic cigarette 100 that does not flow out smoke is: the control circuit 170 cuts off power to the atomizing assembly 120 (the smoke generating device) so that the atomizing assembly 120 in the electronic cigarette 100 no longer generates smoke. In other embodiments, the control scheme of the electronic cigarette 100 that does not flow out smoke may be replaced with: the air flow passage 150 is blocked by the electrically operated valve to block the air flow.

To better protect the user's health, in operation b, when the smoke sensor 180 has not passed through the concentration data of the smoke in the designated area 190, and the current instantaneous data reaches the preset concentration (the maximum value), the control circuit 170 controls the electronic cigarette 100 to not flow out smoke (in other embodiments, the alarm element 174 may be selected to give a reminder to remind the user that the smoke concentration is too high, so as to pay attention to health).

For better health of the user, in other embodiments, a time interval between the sucking and the last sucking of the electronic cigarette 100 may be calculated after the operation a, and if the time interval is less than the set time interval, the operation after the operation b is not performed, or the electronic cigarette 100 is controlled to produce no smoke, or the airflow channel 150 is closed to block the airflow, or a reminder is made.

As an optimization of this embodiment, in other embodiments, a time interval including calculating the time interval between the time when the electronic cigarette 100 was smoked last time and the time when the time interval is less than or equal to a predetermined time (for example, set to 1 minute), the same smoking is considered; at this time, the operation d is replaced by counting the sum of the smoke outflow amounts of the electronic cigarette 100 in the same smoking, and when the sum reaches a predetermined value, the electronic cigarette 100 does not outflow smoke. The purpose of this is to count the total amount of smoke inhaled by the user when smoking a cigarette intermittently.

As shown in fig. 5, in other embodiments, the overall space of the designated area 190 'is trapezoidal, and the smoke inlet 191' and the smoke outlet 192 'are respectively disposed on the sides of the trapezoid on the designated area 190' and near both ends. The light emitting unit 181 is located at the top end face of the trapezoid having a smaller area on the designated area 190', and the light receiving unit 182 is located at the top end face of the trapezoid having a larger area on the designated area 190'. The inclination angle of the trapezoid side surface and the smaller area top end surface in the designated area 190' is similar to the maximum emission angle of the light emitting unit 181.

Fig. 6 is a schematic flow chart of a working method of the electronic cigarette corresponding to the implementation environment. Specifically, the working method comprises the following steps:

S101, judging whether the sucking end 112 in the electronic cigarette 100 is sucked or not, if so, executing the subsequent steps, otherwise, not performing any action. The scheme for judging whether the electronic cigarette 100 is smoked is as follows: the air pressure switch 161 detects whether or not the air pressure in the air flow path 150 has decreased, and if so, the air pressure is considered to be sucked. In other embodiments, the scheme for determining whether the electronic cigarette 100 is smoked may be replaced with: by providing a contact sensor (e.g., a contact switch) at the suction end 112, it is detected whether the mouth contacts the suction end of the electronic cigarette; or the control circuit 170 detects whether a switch controlling the electronic cigarette 100 to produce smoke is touched.

S102, the smoke sensor 180 detects the concentration of smoke passing through the designated area 190, and obtains the concentration data of the electronic cigarette 100 at the time of suction.

S103, when the instantaneous data in the concentration data of the smoke passing through the designated area 190 reaches the preset concentration (the maximum value), step S107 is performed; when the preset concentration (the maximum value) is not reached, step S105 is performed.

And S104, the flowmeter 160 detects the flow rate of the gas passing through the airflow channel 150 in the electronic cigarette 100, and obtains flow data under the pumping time. The method for detecting the flow rate of the gas passing through the gas flow channel 150 in the electronic cigarette 100 is as follows: the flow rate of the gas entering the gas flow channel 150 from the gas flow inlet 151 is detected by the flow meter 160. In other embodiments, the method of detecting the flow of gas through the airflow channel 150 in the e-cigarette 100 may also be modified as follows: a flow meter is provided at the smoke inlet 191 or the smoke outlet 192 of the designated area 190 to detect the flow rate of the gas passing through the designated area 190; or a flow meter may be provided at the gas flow outlet 152 to detect the flow rate of the gas flowing out of the gas flow channel 150.

S105, the processor 173 calculates the amount of smoke flowing out of the electronic cigarette 100 (the airflow outlet 152) at the time of suction based on the detected concentration data and the detected flow data.

S106, the processor 173 judges whether the outflow reaches a set value, and when the outflow reaches the set value, the step S107 is executed; if the set value is not reached, step S101 is performed (step S105 may be performed instead in other embodiments).

S107, the electronic cigarette 100 does not flow out smoke (and may be optionally set to make a reminder to remind the user of health). The control scheme of the electronic cigarette 100 that does not flow out smoke is: the control circuit 170 cuts off power to the atomizing assembly 120 (the smoke generating device) to control the atomizing assembly 120 in the electronic cigarette 100 to no longer generate smoke. In other embodiments, the control scheme of the electronic cigarette 100 that does not flow out smoke may be replaced with: the air flow passage 150 is blocked by the electrically operated valve to block the air flow.

To better protect the user's health, in other embodiments, as shown in fig. 7, the workflow of the electronic cigarette may be modified to include the following steps:

s201, judging whether the sucking end 112 in the electronic cigarette 100 is sucked or not, if so, executing the subsequent steps, otherwise, not performing any action. The scheme for judging whether the electronic cigarette 100 is smoked is as follows: the air pressure switch 161 detects whether or not the air pressure in the air flow path 150 has decreased, and if so, the air pressure is considered to be sucked. In other embodiments, the scheme for determining whether the electronic cigarette 100 is smoked may be replaced with: by providing a contact sensor (e.g., a contact switch) at the suction end 112, it is detected whether the mouth of the person contacts the suction end 112 of the electronic cigarette 100; or the control circuit 170 detects whether a switch controlling the electronic cigarette 100 to produce smoke is touched.

S202, the processor 173 calculates the time interval between this suction and the last time the electronic cigarette 100 was sucked.

S203, judging whether the time interval is smaller than the set time (for example, set to 2 hours), if the time interval is smaller than the set time, executing step S209; if the time interval is greater than or equal to the set time, the steps after step S204 are performed. The purpose of the set time is to prevent the user from smoking a second time without the interval time being long.

s301, judging whether the sucking end 112 in the electronic cigarette 100 is sucked or not, if so, executing the subsequent steps, otherwise, not performing any action. The scheme for judging whether the electronic cigarette 100 is smoked is as follows: the air pressure switch 161 detects whether or not the air pressure in the air flow path 150 has decreased, and if so, the air pressure is considered to be sucked. In other embodiments, the scheme for determining whether the electronic cigarette 100 is smoked may be replaced with: by providing a contact sensor (e.g., a contact switch) at the suction end 112, it is detected whether the mouth of the person contacts the suction end 112 of the electronic cigarette 100; or the control circuit 170 detects whether a switch controlling the electronic cigarette 100 to produce smoke is touched.

In other embodiments, the method of detecting the flow of gas through the airflow channel 150 in the e-cigarette 100 may also be modified as follows: a flow meter is provided at the smoke inlet 191 or the smoke outlet 192 of the designated area 190 to detect the flow rate of the gas passing through the designated area 190; or a flow meter may be provided at the gas flow outlet 152 to detect the flow rate of the gas flowing out of the gas flow channel 150.

Second embodiment

Fig. 9 and 10 are schematic views of an implementation environment of an atomizing device 200 according to a preferred embodiment of the present invention. The aerosolization apparatus 200 includes an outlet end 210, an airflow channel 220, a designated area 221, a flow meter 230 for detecting the flow of gas, a gas pressure switch 240, a control circuit 250, an aerosolization assembly 260, a smoke sensor 270 for detecting the concentration of aerosol, and a cavity 280 for storing aerosol-generating material. Airflow channel 220 includes an airflow inlet 222 and an airflow outlet 223 at outlet end 210. The atomizing assembly 260 is configured to atomize a substance to be atomized to generate an aerosol, and the generated aerosol flows out of the airflow outlet 223 after passing through the airflow channel 220, and is finally inhaled by a user. In the present embodiment, the flow meter 230 is adjacent to the air inlet 222 to detect the flow rate of the air flowing from the air inlet 222, and the air pressure switch 240 is disposed above the flow meter 230.

In this embodiment, the aerosol-generating material is exemplified as a liquid, and the atomizing assembly 260 includes a liquid absorbing member 261 and a heating wire 262, wherein the liquid absorbing member 261 is adapted to absorb the liquid stored in the cavity 280, and the heating wire 262 contacts the liquid absorbing member 261 to heat the absorbed liquid to atomize the liquid into aerosol. In other embodiments, the atomizing assembly 260 may be a high frequency vibration generator, as is appropriate in the practice of the prior art.

As shown in fig. 10, the smoke sensor 270 includes a light emitting unit 271 and a light receiving unit 272, the light emitting unit 271 and the light receiving unit 272 being provided opposite to the designated area 221. The designated area 221 is part of the overall airflow path 220, and in the airflow direction, the designated area 221 is closer to the airflow end than the atomizing assembly 260. There is a bend between the designated area 221 and the main path of the airflow channel 220 (the purpose of the bend is to separate the detection space), and the designated area 221 communicates with the airflow channel 220 by providing an air inlet 224 and an air outlet 225. The aerosol atomized by the atomizing assembly 260 flows out through the designated area 221.

Specifically, the light emitting unit 271 emits photons, the light receiving unit 272 gives corresponding electric signals according to the intensity of the received photons, and the control circuit 250 calculates the concentration of smoke in the designated area 221 according to the different electric signals transmitted from the light receiving unit 272. Preferably, the light emitting unit 271 emits light of a short wavelength. The light emitting unit 271 in this embodiment emits ultraviolet light, which preferably has a wavelength range of 400-405nm. To prevent interference of external light, the inner surface of the designated area 221 is set to black (or the designated area 221 is made of black material).

As shown in fig. 10, the designated area 221 has a trapezoidal overall space, and the air inlet holes 224 and the air outlet holes 225 are respectively provided on the sides of the trapezoid on the designated area 221 and near both ends. The light emitting unit 271 is located at the tip end face of the trapezoid having a smaller area on the specified area 221, and the light receiving unit 272 is located at the tip end face of the trapezoid having a larger area on the specified area 221. The inclination angle of the trapezoid side surface and the smaller area top end surface in the designated area 221 is similar in magnitude to the maximum emission angle of the light-emitting unit 271.

In other embodiments, the inner surface of the designated area 221 may be set to be a flat plane or set to be a mirror surface. The purpose of providing a flat plane or mirror surface is to prevent photons emitted from the light emitting unit 271 from being lost in the designated area 221, and thus the accuracy of detecting data by the smoke sensor 270 can be improved when the correction value is not set.

In other embodiments, the flow meter 230 may be modified to be located at or near the airflow outlet 223, or within the airflow channel 220, or within the designated area 221.

The memory 252 stores a plurality of instruction codes including concentration data, flow rate data, a set value (such as an index of the inhalation amount of the active ingredient), a predetermined value, a preset concentration (an instantaneous concentration maximum value that the active ingredient cannot exceed), a set time (such as set to 2 hours), and the like. The processor 253 can call the instruction code stored in the memory 252 to perform the following operations: a. judging whether the aerosol action of the atomizing device 200 is triggered, and if so, executing subsequent operations; b. the smoke sensor 270 detects the concentration of aerosol passing through the designated area 221, resulting in concentration data at the triggered time; at the same time, the flow meter 230 detects the flow rate of the gas passing through the gas flow channel in the atomizing device 200, and obtains flow rate data at the triggered time; c. the processor 253 counts the outflow amount of the aerosol of the atomizing device 200 at the triggered time according to the detected concentration data and flow rate data (when the timer 251 is not set, the smoke sensor 270 and the flowmeter 230 need to be controlled to work simultaneously so as to improve the accuracy of the counted data); d. when the outflow reaches the set point, the atomizing device 200 is controlled not to flow aerosol or to make a reminder.

In other embodiments, the scheme of determining whether the action of the aerosol by the aerosolization device 200 is triggered may also be replaced with: detecting whether the outlet end 210 of the atomizing device 200 is contacted; or whether a switch controlling the atomizing device 200 to generate aerosol is activated.

In operation d, the control scheme of the atomizing device 200 to not discharge aerosol is: the control circuit 170 cuts off the power to the atomizing assembly 260 so that no aerosol is produced. In other embodiments, the control scheme for the atomizing device 200 not to emit aerosol may also be: the air flow channel 150 is closed to block the air flow.

In operation b, when the instantaneous data in the concentration data measured by the smoke sensor 270 reaches the preset concentration (the maximum value), the atomizing device 200 does not flow out of the aerosol (a reminder may be optionally made).

In other embodiments, the time interval from the last time the atomizing device 200 was triggered may be calculated after the operation a, and if the time interval is less than the set time, the operation after the operation b is not performed, or the atomizing device 200 is controlled not to generate aerosol, or the airflow channel 220 is closed so as to block the airflow, or a reminder is made.

In other embodiments, a time interval including calculating the time interval since the last time the atomizing device 200 was triggered may be further set after operation a, and if the time interval is less than or equal to a predetermined time, the same use of the atomizing device 200 may be considered; at this time, the operation d may be replaced by counting the sum of aerosol outflow amounts of the atomizing device 200 in the same use, and controlling the atomizing device 200 not to flow aerosol or to make a reminder when the sum reaches a predetermined value.
