IMPLEMENTATION OF THE INVENTION

[0050] For a better understanding of the technical features, objects and effects of the present invention, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0051] Embodiment 1:

[0052] An electronic atomizer as shown in FIG. 2, contains a liquid storage unit 1, configured to store the sprayed liquid, a spray unit 2 located under the liquid storage unit 1, an air supply unit 3, configured to supply air to the liquid storage unit 1 to change the air pressure in unit 1 for storing liquid so as to supply liquid to the spray unit 2, a switching unit 5 configured to control the spray unit 2, and a control unit 4 configured to control the operation of the air supply unit 3, wherein the switching unit 5 includes an induction an air flow switch or a push switch is connected to the control unit 4 and is configured to control the on/off control of the spray unit 2.

[0053] The operating principle of the electronic atomizer is as follows: when a change in air pressure in the atomization unit 2 is detected (that is, when the user takes a puff), the circuit of the atomization unit 2 is controlled to close by means of a push switch or an inductive air flow switch of the switching unit 5. When the atomizer unit 2 operates, the atomized liquid will be consumed, the air supply unit 3 supplies and delivers air to the liquid storage unit 1, and with the increase in air pressure in the liquid storage unit 1, the atomized liquid in the liquid storage unit 1 will be forced out and supplied to atomizing unit 2. It can be understood that the amount of air supplied by unit 3 to supply air to liquid storage unit 1 is equivalent to the amount of atomizing liquid supplied by liquid storage unit 1 to atomizing unit 2, the supplied atomizing liquid will be consumed by atomizing unit 2 to atomize , and it is necessary to maintain a balance between the amount of spray liquid consumed and the amount of spray liquid supplied to the spray unit 2. The amount of air supplied by the air supply unit 3 is related to the air supply speed and the operating time (i.e. air supply time) of the air supply unit 3, so the amount of liquid supplied by the liquid storage unit 1 can be determined in accordance with the air supply speed and the operating time of the air supply unit 3. The amount of atomizing liquid consumed by the atomizing unit 2 is related to the output power and operating time (i.e., atomizing time) of the atomizing unit 2, the heat generation rate can be determined according to the output power of the atomizing unit 2, and the consumption rate of the atomizing liquid can be determined according to the heat generation rate, so the amount of atomizing liquid consumed by the atomizing unit 2 can be converted into the amount of air supplied by the air supplying unit 3 at a certain output power; then the corresponding relationship between the operating time ratio of the air supply unit 3 to the operating time of the spray unit 2 and the power of the spray unit 2 can be obtained, and the amount of atomizing liquid supplied to the spray unit 2 can be controlled by controlling the operating cycle of the air supply unit 3 maintaining a balance between the amount of atomizing liquid consumed and the amount of atomizing liquid supplied to the atomizing unit 2, which avoids liquid leakage and dry burning of the atomizing core.

[0054] Specifically, as shown in FIG. 1, the liquid supply method includes the following steps:

[0055] Step S1, in which the atomizing unit 2 is connected to the circuit, and then the atomizing parameter of the atomizing unit 2 is detected and obtained, wherein the atomizing parameter contains the resistance of the atomizing unit 2.

[0056] Step S2, in which the real-time power of the atomizing unit 2 is calculated in accordance with the atomizing parameter: the real-time power of the atomizing unit 2 is calculated in accordance with the resistance of the atomizing unit 2 detected in real time. Specifically, the real-time power calculation includes: obtaining the real-time resistance and output voltage of the atomizing unit 2; and calculating the real-time power of the atomizing unit 2 according to the resistance, voltage and power ratio and the resistance of the atomizing unit 2, wherein the resistance, voltage and power ratio of the atomizing unit 2 is P=U²/R (P is power, U is voltage , and R - resistance). Thus, after connecting the atomizing unit 2 to the circuit, the real-time power of the atomizing unit 2 can be calculated according to the detected resistance and voltage of the atomizing unit 2.

[0057] Step S3, in which the ratio of the operating time of the power supply unit 3 to the operating time of the atomizing unit 2 is determined in accordance with the real-time power calculated in step S2.

[0058] Specifically, step S3 includes obtaining a corresponding ratio between the operating time and power, wherein the corresponding relationship between the operating time and power is the ratio between the operating time of the air supply unit 3 to the operating time of the atomizing unit 2 and the power of the atomizing unit 2.

[0059] The ratio of the operating time of the air supply unit 3 to the operating time of the atomizing unit 2 is determined according to the corresponding relationship between the operating time ratio and the power and real-time power, wherein the ratio of the operating time of the air supply unit 3 to the operating time of the atomizing unit 2 less than or equal to 1.

[0060] Step S4, which determines the operating cycle of the air supply unit 3 in accordance with the operating time ratio.

[0061] Specifically, the atomizing time (operating time) of the atomizing unit 2 is obtained, and the duty cycle of the air supply unit 3 is calculated according to the operating time ratio.

[0062] Step S5, in which, with the switching unit 5 turned on, the air supply unit 3 is controlled to supply air to the liquid storage unit 1 according to the duty cycle.

[0063] The relationship between the ratio of the operating time of the air supply unit 3 to the operating time of the atomizing unit 2 and the power of the atomizing unit 2 can be obtained by testing through the following steps: standard samples of the atomizing unit 2 with different powers are tested to detect the atomizing liquid consumption of the atomizing unit 2 for a fixed spray time at different powers and is converted into the consumption rate of the spray liquid of the spray unit 2; the amount of atomized liquid displaced from the liquid storage unit 1 (that is, the amount of atomized liquid supplied to the atomized unit 2) when the air supply unit 3 supplies air to the liquid storage unit 1 for a fixed operating time is detected by testing and is converted into a liquid supply rate to the spray unit 2, and the amount of air supplied by the air supply unit 3 (that is, the amount of spray liquid supplied by the liquid storage unit 1) for a fixed time is obtained. The corresponding ratio between the power of the spray unit 2 and the amount of spray liquid consumption can be obtained by testing, the corresponding ratio between the spray liquid supply and the spray liquid consumption of the air supply unit 3 and the spray unit 2 during the same operating time is obtained, and the the corresponding relationship between the liquid supply speed and the liquid consumption speed of the spray unit 2; and finally, the ratio of the operating time of the air supply unit 3 to the operating time of the atomizing unit 2 at different powers of the atomizing unit 2 can be determined in accordance with the requirement of maintaining a balance between the supply of atomizing liquid and the consumption of the atomizing unit 2 in actual use.

[0064] The data list is compiled in accordance with the data obtained by testing and is pre-stored in the control unit 4; in practical operation, the control unit 4 finds the corresponding running time ratio from the specified data list according to the real-time recognized power of the atomizing unit 2, and obtains the required duty cycle of the air supply unit 3 according to the operating time ratio and the actual operating time of the atomizing unit 2; and with the switching unit 5 turned on, the air supply unit 3 is controlled to supply air to the liquid storage unit 1 in accordance with the operating cycle. Or, in accordance with the data obtained by testing, a dependence graph is constructed for the ratio of the operating time of the air supply unit 3 to the operating time of the spray unit 2 and the power of the spray unit 2, and the dependence graph may be a curve of experimental points previously stored in the control unit ; In practical operation, the control unit 4 finds the corresponding running time ratio based on the curve of the experimental points according to the real-time recognized power of the spray unit 2, and obtains the required duty cycle of the air supply unit 3 according to the running time ratio and the actual running time of the spray unit 2 (user’s actual hovering time); and with the switching unit 5 turned on, the air supply unit 3 is controlled to supply air to the liquid storage unit 1 in accordance with the operating cycle. Or, in accordance with the data obtained by testing, a dependence graph is constructed for the ratio of the operating time of the air supply unit 3 to the operating time of the spray unit 2 and the corresponding power of the spray unit 2, and the dependence graph may be a line graph or a broken line graph, the line graph can be progressive or stepped, as shown in FIG. 3 - fig. 4, and the line graph or broken line graph is previously stored in the control unit 4; In practical operation, the control unit 4 finds the corresponding running time ratio based on the line graph according to the real-time recognized power of the spray unit 2, and obtains the required duty cycle of the air supply unit 3 according to the running time ratio and the actual running time of the spray unit 2 ( user's actual hovering time); and with the switching unit 5 turned on, the air supply unit 3 is controlled to supply air to the liquid storage unit 1 in accordance with the operating cycle. In this way, a balance is maintained between the consumption of atomizing liquid and the supply of the atomizing unit 2, which solves the problems of liquid leakage and dry burning and improves the user's mouthfeel.

[0065] In one specific implementation, 11 standard atomizer blocks with different resistances were tested at an output voltage of 4.2 V, with the powers of the standard atomizer block 2 being calculated by the formula P=U²/R, and the standard samples of the atomizing block 2 with different powers set into electronic atomizers to form a plurality of electronic atomizers, which were tested as follows: the user took each puff for 2 seconds and then stopped for 8 seconds, the amount of air inhaled by the user with each puff was 35 ml, and the vaping rate was 17.5 ml/s; To obtain the mass of atomized liquid consumed per puff, e-liquids were weighed before consuming atomized liquid (before vaping) and after consuming atomized liquid (after 100 puffs), and through testing, the density of e-liquid was 1.14 g/ml, so Thus, the volume of liquid consumed by each puff was obtained (the amount of atomized liquid consumed by each puff). Specific test data is presented in Table 1:

[0066] Table 1 Test data for 11 standard atomization block samples with different resistances Series number Resistance of standard samples of atomizing block (Ohm) Power of standard samples of spray unit (W) Weight reduction after 100 puffs (g) Nebulized liquid consumption per puff (mg) 1 0.45 39.2 1.55 15.5 2 0.5 35.2 1.35 13.5 3 0.6 29.4 1.05 10.5 4 0.8 22 0.88 8.8 5 0.9 19.6 0.81 8.1 6 1.0 17.6 0.77 7.7 7 1.1 16 0.73 7.3 8 1.2 14.7 0.71 7.1 9 1.3 13.5 0.67 6.7 10 1.4 12.6 0.6 6 eleven 1.5 11.7 0.56 5.6

[0067] A graph of the atomizing liquid consumption of the atomizing unit 2 (atomizing liquid consumption of each puff) and the power of the atomizing unit 2 (standard samples of the atomizing unit 2) is plotted according to the above data, as shown in FIG. 3; Through testing, it can be found that as the power of the spray unit 2 increases, the consumption of the spray liquid will become larger, and the amount of air that needs to be supplied to the liquid storage unit 1 using the air supply unit 3 will become longer, so the air supply time of unit 3 to There will be more air supply, and the duty cycle of air supply unit 3 will be longer.

[0068] Through testing, relevant data of the air supply unit 3 was detected, the data including the amount of air supplied by the air supply unit 3 (atomization liquid supplied amount) for a fixed time; the corresponding relationship between the supply of the spray liquid and the consumption of the spray liquid during the same operating time of the air supply unit 3 and the spray unit 2 was obtained, and the corresponding relationship between the liquid supply rate and the liquid consumption rate of the spray unit 2 was obtained; A graph of the ratio of the operating time of the air supply unit 3 to the operating time of the atomizing unit 2 and the power of the atomizing unit 2 was prepared in accordance with the data obtained by testing, and in one specific implementation, the resulting graph is shown in FIG. 4; the dependence graph is previously stored in control block 4; After connecting the atomizer 2 to the 4.2V circuit, the resistance of the atomizer 2 was automatically recognized as 1.0 ohms, the voltage of the atomizer 2 was 4.2V, the real-time power of the atomizer 2 was 17.6W, obtained by recognition and calculation, and the control unit 4 calculated that the ratio of the operating time corresponding to the real-time power of 17.6 W, in accordance with the dependence graph previously stored therein, was 0.36; the actual vaping time of the user was 1 s, so the duty cycle of the air supply unit 3 was 36%; and with the switching unit 5 turned on, the air supply unit 3 was controlled to supply air to the liquid storage unit 1 according to the air duty cycle, that is, the air supply unit 3 was very often started and stopped according to the 36% duty cycle during the user's soaring time was 1 s, and the proportion of time the unit 3 circuit was turned on for air supply was 36%.

[0069] In another specific embodiment, the resulting plot is shown in FIG. 5; the dependence graph was previously saved in control block 4; After connecting the atomizer 2 to the 4.2V circuit, the resistance of the atomizer 2 was automatically recognized as 0.45 ohms, the voltage of the atomizer 2 was 4.2V, the real-time power of the atomizer 2 was 39.2W, obtained by recognition and calculation, and the control unit 4 calculated that the ratio of the operating time corresponding to the power of 39.2 W in real time, in accordance with the dependence graph previously stored therein, was 0.8; the user's actual vaping time was 1 s, so the duty cycle of the air supply unit 3 was 80%; and with the switching unit 5 turned on, the air supply unit 3 was controlled to supply air to the liquid storage unit 1 according to the air duty cycle, that is, the air supply unit 3 was very often started and stopped according to the 80% duty cycle within the user's soaring time was 1 s, and the proportion of time the unit 3 circuit was turned on for air supply was 80%.

[0070] Embodiment 2:

[0071] An electronic atomizer as shown in FIG. 2, contains a liquid storage unit 1, configured to store the sprayed liquid, a spray unit 2 located under the liquid storage unit 1, an air supply unit 3, configured to supply air to the liquid storage unit 1 to change the air pressure in a liquid storage unit so as to supply liquid to the spray unit 2, a switching unit 5 configured to control the spray unit 2, and a control unit 4 configured to control the operation of the air supply unit 3, wherein the switching unit 5 includes an induction switch air flow or push switch, connected to the control unit 4 and configured to control the on/off of the spray unit 2.

[0072] The operating principle of the electronic atomizer is as follows: when a change in air pressure in the atomizer unit 2 (when the user smokes) is detected, the atomizer unit 2 is controlled to be connected to the circuit by a push switch or an inductive air flow switch of the switching unit 5; when the spray unit 2 is working, the spray liquid will be consumed, the air supply unit 3 will supply and deliver air to the liquid storage unit 1, and with the increase of air pressure in the liquid storage unit 1, the spray liquid in the liquid storage unit 1 will be forced out and supplied into spray unit 2; It can be understood that the amount of air supplied by the unit 3 to supply air to the liquid storage unit 1 is equivalent to the amount of atomizing liquid supplied by the liquid storage unit 1 to the atomizing unit 2, the supplied atomizing liquid will be consumed by the atomizing unit 2 to atomize, and maintenance is required balance between the consumption of the sprayed liquid and the supply of the sprayed liquid of the spray unit 2; the amount of air supplied by the air supply unit 3 is related to the output power and running time (air supply time) of the air supply unit 3, so the air generation speed (air supply speed) can be determined in accordance with the output power of the air supply unit 3 ; the amount of atomizing liquid consumed by the atomizing unit 2 is related to the power output and operating time (atomizing time) of the atomizing unit 2, the heat generation rate can be determined according to the output power of the atomizing unit 2, and the atomizing liquid consumption rate can be determined according to heat generation rate, so the amount of atomizing liquid consumed by the atomizing unit 2 can be converted into the amount of air supplied by the unit 3 to supply air for the same operating time (the air supply time is equal to the atomizing time); the output power required by the air supply unit 3 is calculated in accordance with the required air supply, and the amount of atomizing liquid supplied to the atomizing unit 2 can be controlled by controlling the output power of the air supply unit 3 to maintain a balance between the atomizing liquid consumption and the atomizing supply liquid of the atomizing unit 2, which avoids liquid leakage and dry burning of the atomizing core.

[0073] Specifically, as shown in FIG. 6, the liquid supply method includes the following steps:

[0074] Step S1, in which the atomizing unit 2 is connected to the circuit, and then the atomizing parameter of the atomizing unit 2 is recognized and obtained, wherein the atomizing parameter contains the resistance of the atomizing unit 2.

[0075] Step S2, in which the real-time power of the atomizing unit 2 is calculated in accordance with the atomizing parameter: the real-time power of the atomizing unit 2 is calculated in accordance with the resistance of the atomizing unit 2 detected in real time. Specifically, the resistance, voltage, and power ratios of the atomizing unit 2 are obtained in real time; and calculating the real-time power of the spray unit 2 in accordance with the ratio of resistance, voltage and power, as well as the resistance of the spray unit 2, and the ratio of resistance, voltage and power of the spray unit 2 is P=U²/R (P - power, U - voltage, and R - resistance). Thus, after connecting the atomizing unit 2 to the circuit, the real-time power of the atomizing unit 2 can be calculated according to the detected resistance and voltage of the atomizing unit 2.

[0076] Step S3, which determines the output power of the air supply unit 3 in accordance with the real-time power calculated in step S2.

[0077] Step S4, in which, with the switching unit 5 turned on, the air supply unit 3 is controlled to supply air to the liquid storage unit 1 in accordance with the output power.

[0078] In addition, in step S3, a power threshold value is obtained; The real-time power of the spray unit 2 is compared with a power threshold; and if the real-time power is less than the power threshold, the output power of the air supply unit 3 is set to half the power; or if the real-time power is equal to or greater than the power threshold, the output power of the air supply unit 3 is set to full power.

[0079] The threshold power value can be obtained through testing through the following steps: standard samples of the spray unit 2 with different powers are tested to detect the spray liquid consumption of the spray unit 2 for a fixed spray time at different powers, obtain the corresponding ratio between the spray liquid consumption of the spray unit unit 2 and the power of the spray unit 2, and the consumption of the sprayed liquid is in a positive relationship with the power of the spray unit, that is, the consumption of the sprayed liquid will increase with increasing power of the spray unit 2 and decrease with decreasing power of the spray unit 2; a power threshold value can be set according to a corresponding ratio, and the consumption of a spray liquid corresponding to the power threshold value can be detected on the curve; The real-time power of the spray unit 2 is compared with a power threshold; if the real-time power is less than the power threshold, the output power of the air supply unit 3 will be low; or, if the real-time power exceeds the power threshold, the power output of the air supply unit 3 will be high.

[0080] The power threshold of the atomizing unit 2 is set to 20 W. When the real-time power of the atomizing unit 2 reaches the power threshold, that is, the real-time power of the atomizing unit 2 is greater than or equal to 20W, the atomizing unit 2 will consume a small amount of atomizing liquid, and to maintain the balance between the atomizing liquid supply and the atomizing unit consumption the unit 2 should supply a large amount of atomizing liquid, the output power of the air supply unit 3 should be high to ensure that a large amount of air is supplied by the air supply unit 3 to ensure that a large amount of liquid is expelled from the liquid storage unit 1; and in this case, it is required to operate the air supply unit 3 at full power to maintain the balance between the supply of atomizing liquid and the consumption of the atomizing unit 2. When the real-time power of the atomizing unit 2 does not reach the power threshold, that is, the real-time power of the atomizing unit 2 is less than 20W, the spray unit 2 will consume a small amount of atomizing liquid, and in order to maintain the balance between the supply of atomizing liquid and the consumption of the spray unit 2, a small amount of atomizing liquid should be supplied, the output power of the air supply unit 3 must be low to ensure supply a small amount of air by the air supply unit 3 to displace a small amount of liquid from the liquid storage unit 1; and in this case, it is required to operate the air supply unit 3 at only half power to maintain a balance between the supply of atomizing liquid and the consumption of the atomizing unit 2. Thus, the problems of liquid leakage and dry burning are solved, and the user's mouthfeel is improved.

[0081] In one particular implementation, 11 standard atomizer block 2 samples with different resistances were tested at an output voltage of 4.2 V, the powers of the standard atomizer block 2 samples were calculated using the formula P=U²/R, and the standard samples of atomizer block 2 with different powers were set into electronic atomizers to form a plurality of electronic atomizers, which were tested as follows: the user took each puff for 2 seconds and then stopped for 8 seconds, the amount of air the user inhaled in each puff was 35 ml, and the vaping rate was 17.5 ml/ With; e-liquids were weighed before consuming atomized liquid (before vaping) and after consuming atomized liquid (after 100 puffs) to obtain the mass of atomized liquid consumed by each puff, and through testing, the density of the e-liquid was 1.14 g/ml, thus, obtained the volume of liquid consumed by each puff (consumption of atomized liquid by each puff). Specific test data is presented in Table 2:

[0082] Table 2. Test data for 11 standard spray block samples with different resistances Series number Resistance of standard samples of atomizing block (Ohm) Power of standard samples of spray unit (W) Weight reduction after 100 puffs (g) Nebulized liquid consumption per puff (mg) 1 0.45 39.2 1.55 15.5 2 0.5 35.2 1.35 13.5 3 0.6 29.4 1.05 10.5 4 0.8 22 0.88 8.8 5 0.9 19.6 0.81 8.1 6 1.0 17.6 0.77 7.7 7 1.1 16 0.73 7.3 8 1.2 14.7 0.71 7.1 9 1.3 13.5 0.67 6.7 10 1.4 12.6 0.6 6 eleven 1.5 11.7 0.56 5.6

[0083] A graph of the atomizing liquid consumption of the atomizing unit 2 (atomizing liquid consumption of each puff) and the power of the atomizing unit 2 (standard samples of the atomizing unit 2) is plotted according to the above data, as shown in FIG. 3. From the test results, it can be learned that as the power of the spray unit 2 increases, the consumption of the spray liquid will be greater and the required output power of the air supply unit 3 will be greater, and that with the reduction of the power of the spray unit 2 the consumption of the spray liquid will be less and the required output the power of unit 3 for air supply will be less; wherein the threshold power value is set equal to 20 W in accordance with the dependence graph and is previously stored in the control unit 4.

[0084] In one particular implementation, the power threshold was set to 20 W and previously stored in the control unit 4; After connecting atomizer 2 to the circuit with an output voltage of 4.2 V, the resistance of atomizer 2 was automatically recognized as 1.0 ohms, the voltage of atomizer 2 was 4.2 V, and the real-time power of atomizer 2 was 17.6 W obtained by recognizing and calculating that is less than 20 W, so the control unit 4 determined that the output power of the air supply unit 3 was half the power; and with the switching unit 5 turned on, the control unit 4 controlled the air supply unit 3 to supply air to the liquid storage unit 1 at half power.

[0085] In another specific implementation, the power threshold was set to 20 W and previously stored in the control unit 4; After connecting atomizer 2 to the circuit with an output voltage of 4.2 V, the resistance of atomizer 2 was automatically recognized as 0.45 ohms, the voltage of atomizer 2 was 4.2 V, and the real-time power of atomizer 2 was 39.2 W obtained by recognizing and calculating that is greater than 20 W, so the control unit 4 determined that the output power of the air supply unit 3 was full power; and with the switching unit 5 turned on, the control unit 4 controlled the air supply unit 3 to supply air to the liquid storage unit 1 at full power.
