detailed description

To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

The electronic cigarette involved in this application can use a pump to supply liquid to the atomizer. The liquid inlet of the pump is in communication with the liquid storage part in the electronic cigarette, and the liquid outlet of the pump is connected to the atomizing chamber of the atomizer in the electronic cigarette. Connected. For example, a liquid inlet pipe connected to the liquid inlet of the pump may extend into the liquid storage member, and a liquid outlet pipe connected to the liquid outlet of the pump may extend into the atomizing chamber of the atomizer. Optionally, the liquid storage element in the electronic cigarette may be an e-liquid bottle.

Please refer to FIG. 1, which shows a method flowchart of a liquid supply method according to an embodiment of the present invention. This embodiment is described by using the liquid supply method in an electronic cigarette as an example. As shown in FIG. 1, the liquid supply method may include:

In step 110, during the working process of the atomizer, working parameters are obtained, and the working parameters include at least one of the output power of the electronic cigarette, the temperature in the atomizing chamber, and the working voltage of the atomizer.

The realization of this step may be: during the working process of the atomizer, obtaining the working parameters every other unit time period. Among them, the time length corresponding to a unit time period is usually set by the system developer or can be customized by the user. For example, the system developer can set the time length corresponding to a unit time period to be 1 millisecond, 0.5 millisecond, and so on.

In step 120, a liquid supply rule is obtained according to the working parameter, and the liquid supply rule includes a liquid supply duration or a total liquid supply by using a pump to supply liquid to the atomizing chamber of the atomizer within a unit time period.

The following sub-supply rules include two cases: the length of the supply or the total supply:

In the first case, the liquid supply rule includes the liquid supply duration of using the pump to supply liquid to the atomizing chamber within a unit time period. The liquid supply rule obtained according to the working parameter can be implemented in the following two ways:

First, the liquid consumption speed of the atomizer is determined according to the working parameter; the liquid supply time in the liquid supply rule is determined according to the liquid consumption speed and the length of the unit time period.

The e-cigarette can store the correspondence between the nebulizer's liquid consumption speed and the working parameters. The correspondence can be stored in the form of tables, output curves, etc. in the e-cigarette. This correspondence can be passed by the system developer multiple times. Experimental settings; After the electronic cigarette obtains the working parameters by executing step 110, the corresponding consumption relationship is used to query the liquid consumption speed corresponding to the obtained working parameters; according to the liquid consumption speed and the length of a unit time period, the liquid supply rule is determined. The duration of the fluid supply. In the foregoing correspondence relationship, multiple working parameters may correspond to one liquid consumption speed, or one working parameter may correspond to one liquid consumption speed, which is not limited thereto.

Wherein, the realization of the liquid supply duration in the liquid supply rule according to the liquid consumption speed and the length of a unit time period may be: obtaining the working voltage of the pump, and determining the liquid supply speed of the pump according to the working voltage of the pump; The speed, the length of a unit time period, and the pump supply speed determine the duration of the liquid supply.

Optionally, the implementation of determining the liquid supply duration according to the liquid consumption speed, the duration of a unit time period, and the pump supply speed can be realized by calculating the product of the liquid consumption speed and the duration of a unit time period to obtain the unit time period. Consumption of smoke liquid. Determine the consumption of smoke liquid as the total liquid supply required by the atomizer in a unit time period. Obtain the liquid supply speed of the pump and calculate the ratio of the total liquid supply and the liquid supply speed of the pump. Duration of fluid supply.

In actual implementation, the liquid supply duration may be further processed, such as adding a constant, and then increasing the predetermined ratio, etc., which is not specifically limited in this embodiment.

The second method is to check whether the working parameter is a predetermined value. If the working parameter is not a predetermined value, determine the liquid supply duration in the liquid supply rule according to the first method described above. If the working parameter is a predetermined value, obtain the same value as the working parameter. The corresponding liquid supply rule, that is, the liquid supply rule corresponding to the predetermined value is obtained.

The liquid supply rule corresponding to the predetermined value is stored in the electronic cigarette in advance. The liquid supply rule is set by the system developer. The system developer can refer to the first method above when setting the liquid supply time in the liquid supply rule. The method of determining the liquid supply time in the liquid supply rule is determined.

It should be noted that in this embodiment, an example is provided in which an electronic cigarette stores a liquid supply rule corresponding to a predetermined value. In actual implementation, an electronic cigarette may store multiple liquid supply rules, and each liquid supply rule corresponds to a predetermined value. When the working parameter is any predetermined value, the liquid supply rule corresponding to the predetermined value is obtained; when the working parameter is not the predetermined value, the liquid supply time in the liquid supply rule is determined according to the first method.

Optionally, the value of the working parameter is limited in this embodiment. The electronic cigarette stores a liquid supply rule for each value of the working parameter, that is, each value of the working parameter is a predetermined value; obtaining the working parameter The supply rule corresponding to the value of. Taking the working parameter as the output power as an example, the output value of the atomizer of the electronic cigarette is limited. The electronic cigarette stores a liquid supply rule for each value of the output power. The value of the output power of the atomizer is obtained. The value corresponds to the supply rule.

In the second case, the liquid supply rule includes the total amount of liquid supplied by the pump to the atomization chamber in a unit time period. The realization of the liquid supply rule according to the working parameter may be: calculating the liquid consumption rate and a unit time. The product of the length of the segment is used to obtain the smoke liquid consumption in the unit time period, and the smoke liquid consumption is determined as the total liquid supply required by the atomizer in the unit time period to obtain the total liquid supply in the liquid supply rule.

Step 130: Control the pump to supply liquid to the atomizing chamber of the atomizer according to the liquid supply rule.

In the first case, the liquid supply rule includes a liquid supply duration of using a pump to supply liquid to the atomization chamber within a unit time period, and then the pump is controlled to supply the liquid to the atomization cavity for the liquid supply duration within the unit time period. Optionally, the liquid supply is started at the beginning of the unit time period, and the continuous liquid supply reaches the liquid supply time.

For example, during the operation of the atomizer, the output power of the atomizer is obtained every 1 ms, and the liquid supply rule is determined according to the output power. If the liquid supply rule indicates that the liquid supply time is 0.05 ms, the pump is used to spray the mist. The pump stops working after 0.05 milliseconds of liquid supply in the cavity; a new liquid supply rule is obtained the next time the atomizer output power is obtained, and the liquid supply is performed in accordance with the new liquid supply rule.

In the second case, the liquid supply rule includes the total amount of liquid supplied by the pump to the atomization chamber in a unit time period. A detection device is provided in the liquid supply channel used by the pump to supply liquid to the atomization chamber. The detection device detects The information obtained is used to indicate the amount of liquid flowing into the atomization chamber from the liquid supply channel; within the unit time period, the pump is controlled to supply liquid to the atomization chamber until the total amount of liquid supplied to the atomization chamber within the unit time period is obtained. Stop when the total liquid supply in the rule.

Optionally, the liquid supply is started at the beginning of the unit time period, and the liquid supply is continued until the total amount of liquid supplied to the atomizing chamber within the unit time period is stopped when the total liquid supply in the liquid supply rule is obtained.

The detection device may be a detection device for detecting a liquid flow rate or a flow rate, such as a liquid flow rate detector, a liquid flow rate detector, or the like, which is not specifically limited in this embodiment.

Optionally, steps 110 to 130 are performed when the electronic cigarette starts to light, and then steps 110 to 130 are repeatedly performed every other unit time period thereafter.

In summary, the method provided by the embodiment of the present invention obtains working parameters during the working process of the atomizer, and the working parameters include at least one of the output power of the electronic cigarette, the temperature in the atomizing chamber, and the working voltage of the atomizer. Type; obtain the liquid supply rule according to the working parameter, the liquid supply rule includes the liquid supply duration or the total amount of liquid supplied by the pump to the atomizer cavity of the atomizer within a unit time period; and the pump is controlled to the fog according to the liquid supply rule Supply liquid in the cavity; solve the problem that the user has to repeatedly squeeze the e-liquid bottle during the use of the electronic cigarette in the related art; the operation is tedious; and the effect of saving the user's operation during the use of the electronic cigarette is achieved.

In one example, in order to avoid the dry burning problem caused by the consumption speed of the atomizer being higher than the liquid supply speed of the pump, the liquid supply time or supply time in the liquid supply rule is determined according to the liquid consumption speed and the length of a unit time period. Before the total amount of liquid, the electronic cigarette also determines the magnitude relationship between the liquid consumption speed and the first reference value. The first reference value is the maximum liquid supply speed supported by the pump at the highest working voltage; if the liquid consumption speed is higher than The first reference value indicates that the liquid consumption speed of the atomizer is higher than the maximum liquid supply speed of the pump, and dry burning is prone to occur. At this time, a reminder message for indicating that the working parameter is too high is displayed, and / or, the atomizer is controlled. stop working.

The display manner of the reminder message may be any one of electronic cigarette vibration, voice prompt, text prompt, and the like, which is not specifically limited in this embodiment. In addition, the reminder message is displayed to prompt the user to reduce the output power or temperature of the electronic cigarette, thereby reducing the liquid consumption speed of the atomizer.

The pump in the electronic cigarette can support at least one working voltage. The maximum liquid supply speed of the pump is positively related to its working voltage. When the electronic cigarette is controlling the pump to supply liquid to the atomizing chamber, it can control the maximum liquid supply speed supported by the pump according to the current working voltage of the pump. Supply fluid. For example, the pumps currently used in e-cigarettes can support two working voltages, 5V and 3.7V; when the working voltage of the pump is 5V, the pump is controlled to supply at the maximum liquid supply speed when the working voltage is 5V. And the liquid supply duration of the liquid supply rule is determined according to the maximum liquid supply speed; when the working voltage of the pump is 3.7V, the control pump is supplied at the maximum liquid supply speed when the working voltage is 3.7V, and according to the maximum The liquid supply speed determines the liquid supply duration of the liquid supply rule.

Optionally, before determining the liquid supply duration or the total amount of liquid supply in the liquid supply rule according to the liquid consumption speed and the length of a unit time period, the relationship between the liquid consumption speed of the electronic cigarette and the second reference value, the second reference The value is the maximum liquid supply speed supported when the pump works at the minimum working voltage; if the liquid consumption speed is higher than the second reference value, the working voltage of the pump is set higher than the minimum working voltage.

Among them, set the working voltage of the pump to be higher than the minimum working voltage: adjust the working voltage of the pump to the maximum working voltage; or, the pump supports at least three working voltages and increase the working voltage level of the pump until the current working voltage of the pump corresponds to the maximum supply voltage. The liquid speed is higher than or equal to the liquid consumption speed, and the working voltage level of the pump is proportional to the working voltage it supports.

Optionally, if the liquid consumption speed is lower than or equal to the second reference value, the working voltage of the pump is set to the lowest working voltage supported by the pump. In actual implementation, if the liquid consumption speed is lower than or equal to the second reference value, the working voltage of the pump can also be adjusted to the highest working voltage supported by the pump. However, in this method, the electrical energy and heat generated by the pump are both Higher than the way the pump uses the lowest working voltage.

Optionally, in the case that the pump supports only one working voltage in the electronic cigarette, the liquid supply speed of the pump at the working voltage may be stored in the electronic cigarette in advance; the process of determining the liquid supply duration in the liquid supply rule of the electronic cigarette In this case, the liquid supply time stored in the electronic cigarette is calculated using the liquid supply speed stored in the electronic cigarette.

Optionally, in the case that the electronic cigarette supports at least two working voltages, in the process of determining the liquid supply duration in the liquid supply rule: obtaining the working voltage of the pump and determining the liquid supply speed of the pump according to the working voltage of the pump, the The liquid supply speed can be the maximum liquid supply speed of the pump at this working voltage; the total liquid supply required by the atomizer in a unit time is calculated according to the liquid consumption speed and the length of a unit time period; the total liquid supply and the supply are calculated The ratio of the liquid velocity gives the liquid supply time in the liquid supply rule.

In one example, in order to avoid the problem of dry burning when the cigarette is first lit after the electronic cigarette is turned on, the following two implementation manners may be adopted:

First, when the electronic cigarette is turned on, it is detected whether there is liquid in the liquid supply channel used by the pump to supply liquid to the atomizing chamber; when it is detected that there is no liquid in the liquid supply channel, the pump is controlled to work to the liquid supply channel or atomize. Cavity for fluid.

The implementation of detecting whether there is liquid in the liquid supply channel used by the pump to supply liquid to the atomizing chamber may be: setting a pressure sensor or a humidity sensor in the liquid supply channel; if the pressure value detected by the pressure sensor is higher than The first predetermined value determines that there is liquid in the liquid supply channel, otherwise it is determined that there is no liquid in the liquid supply channel; or, when the humidity value detected by the humidity sensor is higher than the second predetermined value, it determines that there is liquid in the liquid supply channel. Liquid, otherwise it is judged that there is no liquid in the liquid supply channel.

Optionally, the pressure sensor and / or the humidity sensor are disposed on the inner wall of the liquid supply channel, for example, on the inner wall of the liquid supply channel near one end of the atomization chamber, or on the middle and one end of the liquid supply channel (near the mist) Anywhere on the inner wall.

Among them, the first predetermined value and the second predetermined value are usually set by the system developer. For example, the system developer can determine the lower limit value detected when the liquid in the liquid supply channel passes the pressure sensor through multiple experiments. Personnel can determine the lower limit of liquid in the liquid supply channel detected by the humidity sensor through multiple experiments.

Optionally, after controlling the operation of the pump to supply liquid to the liquid supply channel, when liquid is detected in the liquid supply channel, it is detected whether there is an atomizable liquid in the atomization chamber of the atomizer; If there is no atomizable liquid in the atomization chamber, the control pump continues to work to supply liquid to the atomization chamber; if there is atomizable liquid in the atomizer, the control pump stops working, and step 110 to step 130 are performed.

The implementation of detecting whether there is an atomizable liquid in the atomizing chamber of the atomizer may be: the pump sprays the liquid sucked from the liquid storage member to the liquid sucking member in the atomizing chamber, and the bottom surface of the liquid sucking member and the mist A pressure sensor in the atomizing chamber is in contact with each other; if the pressure value detected by the pressure sensor is higher than or equal to a third predetermined value, the smoke liquid absorbed by the liquid suction member is considered sufficient and it is determined that there is an atomizable liquid in the atomizer, otherwise It is determined that there is no atomizable liquid in the atomizer.

It should be noted that the third predetermined value is usually set by the system developer. For example, the system developer may determine the lower limit pressure value detected by the pressure sensor when the liquid-absorbing member is saturated, as the third predetermined value.

In addition, if there is no atomizable liquid in the atomizing chamber of the atomizer, the control pump continues to work until the amount of liquid absorbed by the liquid suction member reaches a limit and stops. The specific implementation may be: controlling the pump to continue to work until the pressure value detected by the pressure sensor reaches a third predetermined value and stopping.

Second, when the electronic cigarette is turned on, it is detected whether there is an atomizable liquid in the atomization chamber; if there is an atomizable liquid in the atomization chamber, perform steps 110 to 130; if there is no atomizable liquid in the atomization chamber , The pump is controlled to supply liquid to the atomizing chamber.

Optionally, if there is no atomizable liquid in the atomizing chamber, the pump is controlled to work to supply liquid to the atomizing chamber until the amount of the liquid absorbed by the liquid suction member stops and stops. The specific implementation may be: controlling the pump to continue to work until the pressure value detected by the pressure sensor reaches a third predetermined value and stopping.

In one example, in order to avoid the improper installation of the liquid storage member (for example, the e-liquid bottle), the pump cannot deliver the liquid in the e-liquid bottle to the atomizing chamber, the electronic cigarette is also detected when the e-cigarette is installed; If the installation of the liquid storage member is not correct, the operation of the atomizer is stopped according to the cigarette light signal.

In addition, the installation of the liquid storage component can be detected in the following ways:

The first is to control the pump to work continuously for a predetermined period of time; if there is no liquid in the liquid supply channel during the predetermined period of pump operation, it is determined that the installation of the liquid storage member is incorrect.

The predetermined time is usually set by the system developer. For example, the system developer can determine the maximum time used by the pump to deliver the liquid smoke from the storage part to the liquid supply channel through multiple experiments, and determine the maximum time as the predetermined time.

Second, a pressure sensor is provided on the surface of the liquid storage member, and a component in the liquid storage member presses the pressure sensor when the liquid storage member is correctly installed; if the pressure value detected by the pressure sensor is lower than or equal to the fourth value, Determine that the reservoir is not installed properly. The fourth value is set by a system developer. For example, the fourth value may be 0.

Optionally, before detecting the installation condition of the liquid storage part, the electronic cigarette can also detect whether an atomizer is installed in the electronic cigarette and whether the pump can work normally; if an atomizer is installed in the electronic cigarette and the pump can work normally, Then check the installation of the liquid storage part; if the atomizer is not installed in the electronic cigarette, a prompt message for prompting the installation of the atomizer can be displayed; if the pump does not work normally, it can be displayed for the pump not working properly Prompt message.

Optionally, after detecting the installation condition of the liquid storage part, it is possible to detect whether there is liquid in the liquid supply channel used by the pump to supply liquid to the atomizing chamber; when it is detected that there is no liquid in the liquid supply channel, the pump is controlled to work to Supply liquid to the liquid supply channel or atomizing chamber.

Optionally, after detecting the installation condition of the liquid storage member, before detecting whether there is liquid in the liquid supply channel, check whether there is liquid in the liquid storage member; if there is liquid in the liquid storage member, then check whether there is liquid in the liquid channel. . Wherein, the liquid level detector in the liquid storage element can be used to detect the liquid level in the liquid storage element to detect whether there is liquid in the liquid storage element.
