[0067] DETAILED DESCRIPTION

[0068] The present invention will now be described in detail with reference to the accompanying drawings. This figure is a simplified schematic diagram, which only illustrates the basic structure of the present invention in a schematic manner, and therefore only shows the components related to the present invention.

[0069] Embodiment 1

[0070] Please refer to Figure 1 , which shows a method flow chart of a method for controlling an electronic cigarette provided by an embodiment of the present invention. Figure 1 As shown, the control method of the electronic cigarette may include:

[0071] Step 110, determining the suction force indication information according to the information detected by the detection component, wherein the detection component includes a first air pressure detection member disposed in an air passage connected to the cigarette holder.

[0072] This step can be achieved in the following ways:

[0073] The first method is to obtain the air pressure value detected by the first air pressure detection component to obtain suction force indication information for indicating the suction force of the user.

[0074] In the second method, the air pressure value detected by the first air pressure detection component is not only affected by the user's suction strength, but also by the current atmospheric pressure. The air pressure value detected by the first air pressure detection component cannot accurately reflect the user's suction strength. The air pressure value detected by the first air pressure detection component needs to be combined with the current atmospheric pressure to accurately reflect the user's suction strength. In the second method, the air pressure value detected by the first air pressure detection component can be obtained, and the suction strength indication information is determined based on the air pressure value and the atmospheric pressure.

[0075] Among them, the atmospheric pressure can be obtained in the following ways: 1. Obtaining the reference atmospheric pressure stored in the electronic cigarette; 2. A second air pressure detection component is provided in the electronic cigarette, and the atmospheric pressure value detected by the second air pressure detection component is obtained. The position of the second air pressure detection component in the electronic cigarette is not connected to the mouthpiece of the electronic cigarette. When inhaling, the airflow generated by the inhalation cannot be detected by the second air pressure detection component, so as to ensure that the second air pressure detection component accurately detects the atmospheric pressure value and is not affected by the user's inhalation at the mouthpiece. For example, it can be set on the control panel in the electronic cigarette; 3. Sending a query request to a mobile device within the wireless communication range, the query request is used to trigger the mobile device to obtain its location information using positioning technology and determine the atmospheric pressure value of its location based on the location information, and receive the query result sent by the mobile device carrying the atmospheric pressure value; 4. The electronic cigarette obtains its location information using positioning technology, and sends a query request carrying the location information to the server; the server queries the atmospheric pressure value corresponding to the location information, and sends a query result carrying the atmospheric pressure value to the electronic cigarette.

[0076] Among them, the wireless communication range is the communication range supported by the electronic cigarette using wireless communication technology. The wireless communication technology mentioned here can be any one of Bluetooth, NFC (Near Field Communication), and infrared; the positioning technology can be GPS (Global Positioning System) technology, Wi-Fi (Wireless-Fidelity) positioning technology, etc., which is not specifically limited in this embodiment.

[0077] For example, when an e-cigarette is turned on, it uses Bluetooth technology to scan mobile devices within its wireless communication range and sends a query request to the mobile device; after receiving the query request, the mobile device uses GPS technology to locate its geographic coordinates and sends the geographic coordinates to a server (a server that provides background services for applications installed on mobile devices and is used to manage e-cigarettes); the server queries the atmospheric pressure value corresponding to the geographic coordinates based on the geographic coordinates, and feeds the atmospheric pressure value back to the mobile device; the mobile device sends the query result carrying the atmospheric pressure value to the e-cigarette.

[0078] In one example, before executing step 210, the atmospheric pressure detected by the second air pressure detection component when the electronic cigarette is turned on is obtained, and then the suction strength indication information is determined according to the first air pressure and the atmospheric pressure; in another example, in order to avoid the problem that the suction strength indication information is inaccurate due to the movement of the electronic cigarette and the change of atmospheric pressure during use, the electronic cigarette uses the second air pressure detection component to detect the atmospheric pressure once every predetermined time, and the atmospheric pressure detected by the second air pressure detection component the most recently is obtained before executing step 210. The predetermined time can be set by the system developer or customized by the user.

[0079] Optionally, determining the suction force indication information according to the first air pressure and the atmospheric pressure may be implemented in the following two ways:

[0080] The first method is to calculate the difference between the first air pressure and the atmospheric pressure to obtain the air pressure difference, and use the air pressure difference as the suction force indication information.

[0081] The second method is to calculate the difference between the first air pressure and the atmospheric pressure to obtain the air pressure difference, and calculate the difference between the air pressure difference and the correction air pressure value to obtain the suction force indication information, wherein the correction air pressure value is the air pressure difference between the air pressure in the airway connected to the mouthpiece and the atmospheric pressure when the atomizer stops working.

[0082] Among them, the correction air pressure value can be preset by the system developer, or the electronic cigarette can also obtain the first air pressure value detected by the first air pressure detection component when the atomizer stops working, and simultaneously obtain the second air pressure value detected by the second air pressure detection component, and use the difference between the first air pressure value and the second air pressure value as the correction air pressure value. For example, the electronic cigarette can determine the correction air pressure value according to the first air pressure value detected by the first air pressure detection component and the second air pressure value detected by the second air pressure detection component when the electronic cigarette is turned on. Under normal circumstances, when the user is not inhaling, the first air pressure value detected by the first air pressure detection component and the second air pressure value detected by the second air pressure detection component should theoretically be consistent, both of which are the current atmospheric pressure. However, under the influence of many external factors such as aging of the equipment, the first air pressure value detected by the first air pressure detection component and the second air pressure value detected by the second air pressure detection component may be inconsistent. In this case, the air pressure difference obtained using the first air pressure value and the second air pressure value is inaccurate and cannot accurately reflect the actual suction force of the user. Therefore, when the user is not inhaling, the correction air pressure value is determined according to the first air pressure value detected by the first air pressure detection component and the second air pressure value detected by the second air pressure detection component to correct the air pressure difference and obtain an accurate air pressure difference.

[0083] Step 120, determining a target value of an operating parameter of the atomizer according to the suction force indication information, wherein the operating parameter includes at least one of output power, temperature in the atomization chamber, operating voltage of the atomizer, and temperature of a heating element.

[0084] This step can be achieved in two ways:

[0085] The first one is that if the suction force indication information is greater than the start threshold and lower than the upper limit threshold, the target value of the working parameter is determined according to the first value, the second value, the start threshold, the upper limit threshold and the suction force indication information; if the suction force indication information reaches the upper limit threshold, the second value is determined as the target value of the working parameter.

[0086] Optionally, if the suction force indication information is greater than the start threshold and lower than the upper threshold, the target value of the working parameter is determined according to a predetermined formula, and the predetermined formula is: , W3 is the target value of the working parameter, W1 is the first value, W2 is the second value, A is the start threshold, B is the upper limit threshold, K is the suction strength indication information, m is not zero and is a constant, and C is a constant. For example, m can be 1, and C can be 0. In addition, W3 satisfies: W1≤W3≤W2. Optionally, when the suction strength indication information is the start threshold, the first value is determined as the target value of the working parameter.

[0087] Optionally, when the suction force indication information is a start threshold, the first value is determined as a target value of the working parameter.

[0088] Among them, the start threshold and the upper limit threshold can be set by the system developer, customized by the user, or determined by the electronic cigarette according to the atmospheric pressure; the first value is greater than or equal to the minimum value of the working parameter of the electronic cigarette that can atomize the smoke liquid, the second value is less than or equal to the maximum value of the working parameter supported by the electronic cigarette, and the second value is greater than the first value.

[0089] In actual implementation, the electronic cigarette can directly record the minimum value of the working parameter that can atomize the smoke liquid as the first value (preset by the system developer), and store the maximum value of the working parameter supported by the electronic cigarette as the second value (preset by the system developer).

[0090] In addition, in this application, the lung capacity of electronic cigarette users in high altitude areas is smaller than that in low altitude areas. In order to reduce the difficulty of electronic cigarette users triggering the atomizer to work in high altitude areas, the start threshold can also be determined according to the atmospheric pressure, and the start threshold is positively correlated with the atmospheric pressure. In actual implementation, the correspondence between the atmospheric pressure and the start threshold can be stored in the electronic cigarette, and the start threshold corresponding to the atmospheric pressure can be obtained. The correspondence can be stored in the electronic cigarette in the form of a table, a curve, etc. Similarly, the electronic cigarette can also determine the upper limit threshold according to the atmospheric pressure, and the upper limit threshold is positively correlated with the atmospheric pressure.

[0091] In one example, before the electronic cigarette uses the first control to determine the target value of the working parameter, the electronic cigarette may obtain the first value and / or the second value stored in the electronic cigarette.

[0092] In another example, due to the different boiling points of the e-liquid under different air pressures, the temperature at which the liquid vaporizes will also change accordingly; when the user of the electronic cigarette uses the electronic cigarette in a high altitude area, the boiling point of the e-liquid is lower than that in a low altitude area. In order to avoid the electronic cigarette being unable to atomize smoke when working according to the first value of the working parameter during use in a low altitude area, the first value can be determined according to the atmospheric pressure in this application, and the first value is positively correlated with the atmospheric pressure; optionally, the amount of smoke generated by the electronic cigarette working at different altitudes with the same working parameter is also different, for example, the amount of smoke generated in a high altitude area is higher than that in a low altitude area. In order to avoid excessive smoke and waste of e-liquid in a high altitude area, the second value can also be determined according to the atmospheric pressure in this application. Among them, the first value is positively correlated with the atmospheric pressure, and the second value is positively correlated with the atmospheric pressure.

[0093] In actual implementation, the first value and / or the second value corresponding to the atmospheric pressure may be obtained. The electronic cigarette may store the corresponding relationship between the atmospheric pressure and the first value, and may also store the corresponding relationship between the atmospheric pressure and the second value. These corresponding relationships may be stored in the electronic cigarette in the form of a table, a curve, etc.

[0094] The second method is to query the target value of the working parameter corresponding to the puff strength indication information, and the numerical relationship between the puff strength indication information and the target value is the same as the above-mentioned predetermined formula. The electronic cigarette can store the corresponding relationship between the puff strength indication information and the target value of the working parameter, and the corresponding relationship can be stored in the electronic cigarette in the form of a table, a curve, etc.

[0095] The third method is to determine the preset initial value of the working parameter as the target value of the working parameter when the electronic cigarette is turned on; if the suction force indication information is greater than the adjustment threshold, the target value of the working parameter is increased.

[0096] Among them, the preset initial value can be set by the system developer or customized by the user. For example, the system initial value can be the above-mentioned first value; the adjustment threshold can be set by the system developer or customized by the user.

[0097] Take the working parameter as output power and the first value as 10 watts as an example; the user uses the electronic cigarette to inhale for 5 seconds, and the puff intensity indication information within the 5 seconds is less than the adjustment threshold, then the target value of the working parameter within the 5 seconds is the preset initial value; the user uses the electronic cigarette to inhale for 3 seconds again and increases the puff intensity, so that the puff intensity indication information reaches the adjustment threshold, then the target value of the working parameter is increased.

[0098] Optionally, if the suction force indication information is greater than the adjustment threshold, the target value of the working parameter is increased by a predetermined step length, wherein the predetermined step length may be preset by a system developer or may be customized by a user.

[0099] Optionally, since the atmospheric pressure can also affect the user's vital capacity, the user's vital capacity is smaller in high altitude areas, and small step length adjustment is suitable for high altitude areas, while large step length adjustment is suitable for low altitude areas. Therefore, the predetermined step length can be determined according to the atmospheric pressure, and the predetermined step length is positively correlated with the atmospheric pressure. In actual implementation, the corresponding relationship between the atmospheric pressure and the predetermined step length can be stored in the electronic cigarette, and the predetermined step length corresponding to the atmospheric pressure can be obtained. The corresponding relationship can be stored in the electronic cigarette in the form of a table, a curve, etc.

[0100] Optionally, since the lung capacity of users in high altitude areas is relatively small, in order to reduce the difficulty of users triggering the electronic cigarette to increase the working parameters when using it in high altitude areas, the adjustment threshold can also be determined according to the atmospheric pressure, and the adjustment threshold is positively correlated with the atmospheric pressure. In actual implementation, the corresponding relationship between the atmospheric pressure and the adjustment threshold can be stored in the electronic cigarette, and the adjustment threshold corresponding to the atmospheric pressure can be obtained. The corresponding relationship can be stored in the electronic cigarette in the form of a table, a curve, etc.

[0101] Optionally, since the boiling point of the e-liquid is affected by the atmospheric pressure, in order to prevent the electronic cigarette from failing to atomize smoke when operating at the preset initial value of the working parameter in a low altitude area, the preset initial value of the working parameter can be determined according to the atmospheric pressure, and the preset initial value is positively correlated with the atmospheric pressure. In actual implementation, the corresponding relationship between the atmospheric pressure and the preset initial value can be stored in the electronic cigarette, and the preset initial value corresponding to the atmospheric pressure can be obtained. The corresponding relationship can be stored in the electronic cigarette in the form of a table, a curve, etc.

[0102] Step 130, controlling the atomizer to operate according to the target value of the operating parameter.

[0103] This step can be achieved in two ways:

[0104] The first one is that a cigarette lighting button is provided on the electronic cigarette, and when the electronic cigarette detects an operation signal generated when the cigarette lighting button is operated, the electronic cigarette controls the atomizer to perform atomization; during the atomization process of the atomizer, the atomizer is controlled to work according to the target value of the working parameter.

[0105] The second type is that no lighting button is set on the electronic cigarette; when the suction force indication information reaches the start threshold, the atomizer is controlled to work according to the target value of the working parameter; the number of buttons of the electronic cigarette (for example, the small cigarette) is reduced.

[0106] It should be noted that when the working parameter involved in the present application is the output power or the working voltage of the atomizer, step 130 can be implemented by controlling the working voltage of the atomizer through pulse width modulation technology (PWM).

[0107] In summary, the method provided by the embodiment of the present invention determines the suction force indication information according to the information detected by the detection component, and the detection component includes a first air pressure detection component arranged in the airway connected to the mouthpiece; determines the target value of the working parameter of the atomizer according to the suction force indication information, and the working parameter includes at least one of the output power, the temperature in the atomization chamber, the working voltage of the atomizer, and the temperature of the heating element; controls the atomizer to operate according to the target value of the working parameter; solves the problem in the related art that the small cigarette generates heat according to the preset output power, resulting in a single suction taste; and achieves the effect of enriching the suction taste of the small cigarette.

[0108] An embodiment of the present invention also provides a computer-readable storage medium, which stores one or more instructions. When the one or more instructions are executed by a processor in the electronic cigarette, the electronic cigarette control method involved in any of the above embodiments is implemented.

[0109] An embodiment of the present invention further provides an electronic cigarette control device, the control device comprising: a memory and a processor; the memory stores at least one program instruction; the processor implements the electronic cigarette control method involved in any of the above embodiments by loading and executing the at least one program instruction.

[0111] See also Figure 2-Figure 4 The present invention provides an electronic cigarette, which includes a cartridge 100 and a battery assembly 200 electrically connected to the cartridge 100, wherein the cartridge 100 includes a liquid storage assembly 10 having a liquid storage chamber 110, an atomizer head 20 accommodated in the liquid storage assembly 10, a base 30 installed at one end of the liquid storage assembly 10, and a mouthpiece 40 installed at the other end of the liquid storage assembly 10 relative to the base 30. When in use, the atomizer head 20 heats the smoke liquid stored in the liquid storage chamber 110 under the electric drive of the battery assembly 200, so that the smoke liquid is heated to generate smoke, and the smoke is inhaled by the user.

The cartridge housing 11 is a flat structure, which is a part of the appearance of the cartridge 100. The width of one of the two opposite sides of the cartridge housing 11 is greater than the width of the other two opposite sides, so that the cartridge housing 11 can be stably placed on the table through the side with a larger width, which can effectively prevent the cartridge 100 from rolling down easily. The seal 12 is installed at the lower end of the cartridge housing 11 and closes the end opening. The vent pipe 13 is generally a tubular structure with two ends connected. The vent pipe 13 is accommodated in the inner cavity of the cartridge housing 11, and the upper end of the vent pipe 13 is connected to the top of the cartridge housing 11, and the lower end of the vent pipe 13 is connected to the seal 12. Specifically, the liquid storage chamber 110 is composed of a space composed of the inner wall of the cartridge housing 11, the upper end surface of the seal 12 and the outer peripheral surface of the vent pipe 13. The vent pipe 13 is provided with a smoke outlet channel 130, which is separated from the liquid storage chamber 110 by the tube wall of the vent pipe 13. In addition, the cartridge housing 11 is made of a transparent or translucent material, so that the user can observe the amount of smoke liquid in the liquid storage chamber 110 through the cartridge housing 11, which is convenient for the user to perform the liquid injection operation in time or to facilitate the user to replace the cartridge 100 in time. In this embodiment, the material of the cartridge housing 11 is transparent or translucent plastic.

[0114] The seal 12 is made of silicone material. It can be understood that in other embodiments not shown, the seal 12 can also be made of other sealing materials such as rubber to prevent the leakage of smoke liquid. In this embodiment, a sealing rib (not shown in the figure) is protruded outward along the radial direction of the seal 12 on the outer peripheral surface of the seal 12. There are multiple sealing ribs, and the multiple sealing ribs are sequentially spaced along the axial direction of the seal 12. By providing the sealing ribs, the multi-level sealing of the seal 12 to the liquid storage chamber 110 is achieved, thereby enhancing the sealing performance and further preventing the leakage of smoke liquid.

[0115] A smoke outlet 111 is provided at the top of the cartridge housing 11, and a connecting pipe 112 is formed on the inner circumferential surface of the top wall of the cartridge housing 11, extending downward along the axial direction of the cartridge housing 11. The upper end of the ventilation pipe 13 is inserted into the connecting pipe 112, and the smoke outlet channel 130 is connected to the smoke outlet 111. It can be understood that in other embodiments not shown, the connecting pipe 112 can also be omitted, and in this case, the upper end of the ventilation pipe 13 is directly connected to the smoke outlet 111.

[0116] In this embodiment, the ventilation tube 13 includes a ventilation section 131 and a sleeve section 132 connected to each other, the upper end of the ventilation section 131 is connected to the top of the cigarette cartridge housing 11, and the lower end of the sleeve section 132 is connected to the seal 12. Specifically, the smoke outlet channel 130 is formed by the inner cavity of the ventilation section 131, and the inner cavity of the sleeve section 132 forms a receiving space (not shown in the figure), and the receiving space is connected to the smoke outlet channel 130. The atomizer head 20 is accommodated in the receiving space. In addition, the inner diameter of the ventilation section 131 is smaller than the inner diameter of the sleeve section 132, so that the connection between the ventilation section 131 and the sleeve section 132 forms a supporting plane (not shown in the figure), which facilitates the installation of the atomizer head 20. Specifically, the atomizer head 20 is inserted into the receiving space from the lower end of the sleeve section 132. When the atomizer head 20 is inserted until the upper end of the atomizer head 20 abuts against the abutting plane, it means that the atomizer head 20 is installed in place, that is, the abutting plane limits the installation of the atomizer head 20, thereby facilitating user operation. In this embodiment, the ventilation section 131 and the sleeve section 132 are integrally formed. It can be understood that in other embodiments not shown, the ventilation section 131 and the sleeve section 132 are two independent parts, and when used, the two can be connected together.

[0117] When the vent pipe 13 is installed in place, the sleeve section 132 is partially located in the liquid storage chamber 110, and a liquid inlet 133 is opened on the side wall of the sleeve section 132 located in the liquid storage chamber 110. The liquid inlet 133 is respectively connected to the liquid storage chamber 110 and the receiving space, so that the smoke liquid in the liquid storage chamber 110 can flow into the receiving space through the liquid inlet 133, and then contact the atomizer head 20 to participate in atomization.

[0118] In addition, a liquid injection port 113 is provided on the side wall of the cartridge housing 11, and the liquid injection port 113 is connected to the liquid storage chamber 110. The user can perform liquid injection operation into the liquid storage chamber 110 through the liquid injection port 113, and a sealing plug 114 is sealed and installed on the liquid injection port 113 to prevent the cigarette liquid in the liquid storage chamber 110 from leaking through the liquid injection port 113. Specifically, the sealing plug 114 includes a connecting portion 1141 and a fixing portion 1142 and a sealing portion 1143 respectively installed at both ends of the connecting portion 1141, wherein the fixing portion 1142 is fixedly connected to the cartridge housing 11, and the sealing portion 1143 cooperates with the liquid injection port 113 and is used to seal the liquid injection port 113. When injecting liquid, it is only necessary to open the sealing portion 1143 to expose the liquid injection port 13, and the fixing portion 1142 remains connected to the cartridge housing 11, without removing the entire sealing plug 114, which is convenient for operation and prevents the sealing plug 114 from being lost. In order to ensure that the sealing plug 114 has good sealing performance and the connecting portion 1141 can undergo elastic deformation when the sealing portion 1143 is opened, the sealing plug 114 is an elastic member. It can be understood that the material of the sealing plug 114 includes but is not limited to silicone or rubber.

[0119] In addition, a partition wall (not shown in the figure) is arranged in the cartridge housing 11 along the axial direction of the cartridge housing 11, and the liquid storage chamber 110 is composed of the space composed of the partition wall, the inner wall of the cartridge housing 11 located on one side of the partition wall, the upper end surface of the seal 12 and the outer peripheral surface of the ventilation tube 13. A sensing tube (not shown in the figure) is arranged along the axial direction of the cartridge housing 11 in the space composed of the inner wall of the cartridge housing 11 located on the other side of the partition wall and the partition wall. The sensing tube is integrally formed with the cartridge housing 11, and a sensing chamber 115 is opened in the sensing tube. The sensing chamber 115 is located on one side of the liquid storage chamber 110 and is separated from the liquid storage chamber 110, and the upper end of the sensing chamber 115 passes through the upper end surface of the cartridge housing 11, and the lower end of the sensing chamber 115 is opened. A connecting cavity 116 is provided in the wall of the cartridge shell 11 on the side opposite to the sensing cavity 115 (i.e., the wall of the cartridge shell 11 with the liquid injection port 113), and is located below the liquid injection port 113 and along the axial direction of the cartridge shell 11. An air inlet 117 is provided on the cartridge shell 11 corresponding to the connecting cavity 116. The upper end of the connecting cavity 116 is connected to the air inlet 117, and the lower end of the connecting cavity 116 passes through the lower end surface of the cartridge shell 11.

[0120] The atomizer head 20 includes a liquid-conducting element 21 and a heating element 22 that are in contact with each other. The liquid-conducting element 21 and the heating element 22 are both contained in the containing space. The liquid-conducting element 21 has the ability to absorb smoke liquid, and the heating element 22 can generate heat after being energized. In this embodiment, the liquid-conducting element 21 is a hollow structure with two ends connected, and the inner cavity of the liquid-conducting element 21 constitutes the atomizing cavity 210. The liquid-conducting element 21 is made of a porous material, which is air-permeable and can allow air to be discharged. When the liquid-conducting element 21 is in an adsorption saturation state, it will not further adsorb smoke liquid, thereby sealing the smoke liquid in the liquid storage cavity 110. When the heating element 22 heats the smoke liquid on the liquid-conducting element 21, the liquid-conducting element 21 can adsorb the smoke liquid in the liquid storage cavity 110 again. In this embodiment, the liquid guiding element 21 is coated on the outside of the heating element 22 , and the corresponding liquid inlet 133 is attached to the inner wall of the sleeve section 132 , so that the smoke liquid in the liquid storage chamber 110 is adsorbed into the atomization chamber 210 by the liquid guiding element 21 through the liquid inlet 133 .

[0121] In this embodiment, the heating element 22 is a spiral heating wire, and the liquid-conducting element 21 is cotton. It can be understood that in other embodiments not shown, the heating element 22 can also be a conductive paste, a heating tube, a heating net, etc., and the liquid-conducting element 21 can also be a fiber rope, a sponge, porous ceramics, porous graphite, foam metal, etc. The heating element 22 can also be arranged in the liquid-conducting element 21, which is not limited here.

[0122] Please refer again Figure 4The lower end circumference of the cartridge housing 11 extends downward along the axial direction of the cartridge housing 11 to form a connecting tube 118, and the inner diameter of the connecting tube 118 is greater than the inner diameter of the liquid storage chamber 110. In this embodiment, the connecting tube 118 is integrally formed with the cartridge housing 11. It can be understood that in other embodiments not shown, the connecting tube 118 and the cartridge housing 11 are two independent parts, and when in use, the two can be connected together.

[0123] The base 30 is installed at the lower end of the connecting tube 118. In the present embodiment, the base 30 is snap-connected with the connecting tube 118. It can be understood that in other embodiments not shown, the base 30 and the connecting tube 118 can also be connected in a detachable manner by threaded connection, plug-in connection, magnetic connection, etc., which is not limited here.

[0124] The inner lining member 50 is installed inside the connecting tube 118, and the outer circumference of the lining member 50 is sealed and matched with the inner circumference of the connecting tube 118. The lower end surface of the lining member 50 is in contact with and matched with the upper end surface of the base 30. An air gap 510 is left between the upper end surface of the lining member 50 and the lower end surface of the sealing member 12. One end of the air gap 510 is connected to the lower end opening of the connecting cavity 116, and the other end of the air gap 510 is connected to the atomizing cavity 210. Specifically, a ventilation groove (not shown) is provided on the sealing member 12 below the atomizing head 20, one end of the ventilation groove is connected to the atomizing cavity 210, and the other end of the ventilation groove is connected to the air gap 510, that is, the air gap 510 is connected to the atomizing cavity 210 through the ventilation groove.

[0125] Specifically, the lining member 50 is roughly a plate-like structure, and part of the upper end surface of the lining member 50 corresponds to the sensing chamber 115 and is sealed against the lower end surface of the cigarette cartridge housing 11. Part of the upper end surface of the lining member 50 is recessed downward to form a groove (not shown in the figure), and the two ends of the groove are respectively connected to the atomization chamber 210 and the connecting chamber 116, and the air gap 510 is formed by the groove wall of the groove and the space surrounded by the lower end surface of the seal 12. In this embodiment, the lining member 50 is made of silicone to improve air tightness. It can be understood that in other embodiments not shown, the lining member 50 can also be made of other sealing materials such as rubber.

[0126] A first through hole 501 is provided on the lining member 50 at the lower end corresponding to the sensing chamber 115, and a second through hole 301 is provided on the base 30 at the lower end corresponding to the first through hole 501, and the sensing chamber 115, the first through hole 501 and the second through hole 301 are sequentially connected, and the lower end of the second through hole 301 passes through the lower end surface of the base 30. It can be understood that the lining member 50 plays a role in isolating the sensing chamber 115 and the airflow channel (the air inlet 117, the connecting chamber 116, the air gap 510, the ventilation groove, the atomizing chamber 210 and the smoke outlet channel 130 are sequentially connected to form the airflow channel), so as to prevent the airflow in the sensing chamber 115 and the airflow in the airflow channel from interfering with each other.

[0127] The cigarette cartridge 100 of the present invention also includes a first electrode 60 and a second electrode 70 mounted on the base 30. Specifically, the upper end of the first electrode 60 passes through the base 30 and the lining 50 in sequence and is inserted into the seal 12. The upper end of the second electrode 70 passes through the base 30 and the lining 50 in sequence and is inserted into the seal 12. The heating element 22 has two pins. The upper ends of the first electrode 60 and the second electrode 70 are both opened. One of the pins is inserted into the opening of the first electrode 60, and then a clamping force is applied to the first electrode 60, so that the opening of the first electrode 60 shrinks inwardly to clamp the pin. Similarly, another pin is inserted into the opening of the second electrode 70, and then a clamping force is applied to the second electrode 70, so that the opening of the second electrode 70 shrinks inwardly to clamp the pin. It can be understood that in other embodiments not shown, one pin can be clamped between the first electrode 60 and the seal 12, and the other pin can be clamped between the second electrode 70 and the seal 12. When in use, the first electrode 60 and the second electrode 70 are respectively connected to the positive and negative electrodes of the battery assembly 200, so that the battery assembly 200 supplies power to the heating element 22, and the heating element 22 heats the smoke liquid absorbed by the liquid guide element 21, thereby converting the smoke liquid into smoke. In addition, the base 30, the lining 50 and the sealing member 12 are all made of insulating materials to prevent short circuit failure between the first electrode 60 and the second electrode 70. In this embodiment, the base 30 is made of plastic.

[0128] The mouthpiece 40 is mounted on the upper end of the cartridge housing 11. In this embodiment, the mouthpiece 40 is sleeved on the outer side of the upper end of the cartridge housing 11. Specifically, the mouthpiece 40 is generally a hollow cylindrical structure with an opening at the lower end. A first card slot (not shown) is provided on the outer wall of the cartridge housing 11. A first buckle (not shown) cooperating with the first card slot is convexly provided on the inner wall of the mouthpiece 40. When the mouthpiece 40 is connected to the cartridge housing 11, the first card slot and the first buckle are engaged with each other, thereby realizing a stable connection relationship between the mouthpiece 40 and the cartridge housing 11. When the mouthpiece 40 and the cartridge housing 11 are connected in place, the first card slot and the first buckle are both blocked by the outer wall of the mouthpiece 40, making the cartridge 100 more beautiful as a whole. In this embodiment, there are two first card slots, and the two first card slots are arranged on opposite sides of the cartridge housing 11. Two first buckles are correspondingly arranged, so that the connection between the mouthpiece 40 and the cartridge housing 11 can be made more stable and reliable. It is understandable that in other embodiments not shown, the first buckle is arranged on the inner wall of the cigarette holder 40, and the first slot is arranged on the outer wall of the cigarette cartridge housing 11. It is understandable that in other embodiments not shown, the cigarette holder 40 and the cigarette cartridge housing 11 can also be detachably connected by threaded connection, plug-in connection, magnetic connection, etc., and the detachable structure of the cigarette holder 40 facilitates the cleaning of the cigarette holder 40 and improves the hygiene of use. It is understandable that in other embodiments not shown, the cigarette holder 40 can also be arranged to be non-detachable from the cigarette cartridge housing 11, that is, once the cigarette holder 40 is connected to the cigarette cartridge housing 11, the cigarette holder 40 cannot be removed.

[0129] A smoke outlet 401 is provided at the center of the upper end surface of the cigarette holder 40, and the smoke outlet 401 is connected to the external atmosphere and the inner cavity of the cigarette holder 40. When the cigarette holder 40 and the cigarette cartridge housing 11 are installed in place, the upper end of the sensing cavity 115 is connected to the smoke outlet 401, and the smoke outlet hole 111 is connected to the smoke outlet 401, thereby making the sensing cavity 115 and the smoke outlet channel 130 both connected to the smoke outlet 401. It can be understood that in other embodiments not shown, the cigarette holder 40 can be omitted, and the upper end of the cigarette cartridge housing 11 can be directly used as the cigarette holder.

[0130] See also Figure 5 , Figure 6 The battery assembly 200 includes a battery shell 201, a control board 202 accommodated in the battery shell 201, and a battery 203 installed in the battery shell 201 and located below the control board 202. It can be understood that the cartridge shell 11 and the battery shell 201 together constitute the shell assembly of the electronic cigarette.

[0131] The battery shell 201 is generally a hollow cylindrical structure with an opening at the upper end. The inner cavity of the battery shell 201 forms a receiving cavity 2011, and the lower end of the cartridge housing 11 of the cigarette cartridge 100 is pluggably installed in the upper end of the receiving cavity 2011. In this embodiment, the upper end surface of the battery shell 201 is recessed downward along the axial direction of the battery shell 201 to form a relatively arranged guide groove 2012, and the outer wall of the cartridge housing 11 is convexly provided with a guide rib 119 that cooperates with the guide groove 2012. When the cigarette cartridge 100 is installed in the receiving cavity 2011, the two sides of the guide rib 119 can slide along the two opposite groove walls on the guide groove 2012, thereby guiding the installation of the cigarette cartridge 100. When the cigarette cartridge 100 is installed in place, the sealing plug 114 is shielded, so that the user cannot open the sealing plug 114 to perform the liquid injection operation without pulling out the cigarette cartridge 100. At the same time, only the mouthpiece 13 is exposed outside the receiving chamber 2011, which is convenient for the user to inhale, and the overall length of the electronic cigarette is short, which is convenient for the user to carry. In this embodiment, the guide rib 119 is made of a transparent or translucent material, and the user can observe the amount of liquid in the liquid storage chamber 110 through the guide rib 119, which is convenient for the user to inject liquid or replace the cigarette cartridge 100. In this embodiment, the material of the guide rib 119 is transparent or translucent plastic, and the guide rib 119 is integrally formed with the cigarette cartridge housing 11.

[0132] Also, see Figure 3 , Fig.10 , a protrusion 1101 is convexly provided on the outer wall of the cartridge housing 11. When the cartridge 100 is installed in place, the end of the protrusion 1101 away from the cartridge housing 11 abuts against the inner wall of the battery shell 201, so that a ventilation gap 1102 is formed between the outer wall of the cartridge housing 11 and the inner wall of the battery shell 201. The ventilation gap 1102 is connected to the end of the air inlet 117 away from the connecting cavity 116 and the external atmosphere. In this way, when the user smokes the smoke, the external gas enters the atomizing cavity 210 through the ventilation gap 1102, the air inlet 117, the connecting cavity 116, the air gap 510 and the ventilation groove in sequence and mixes with the smoke. Then, the mixed gas enters the user's mouth through the smoke outlet channel 130, the smoke outlet hole 111 and the smoke outlet 401 in sequence.

[0133] After the cigarette cartridge housing 11 is connected to the battery shell 201, the connection relationship between the cigarette cartridge 100 and the battery assembly 200 is realized. It can be understood that due to the abutment of the protrusion 1101 on the battery shell 201, there is an interactive squeezing force between the cigarette cartridge housing 11 and the battery shell 201, which ensures the stable connection between the cigarette cartridge housing 11 and the battery shell 201 and prevents the cigarette cartridge 100 and the battery assembly 200 from being easily separated.

[0134] In this embodiment, the battery shell 201 includes a first shell 2013 and a second shell 2014, the first shell 2013 and the second shell 2014 are detachably connected or fixedly connected, and the first shell 2013 and the second shell 2014 are connected to form a cylindrical structure with an opening at the upper end, and the receiving cavity 2011 is formed by the inner wall of the first shell 2013 and the inner wall of the second shell 2014. One of the two guide grooves 2012 is arranged on the first shell 2013, and the other is arranged on the second shell 2014. The battery shell 201 is formed by connecting the first shell 2013 and the second shell 2014, so that it is convenient for processing and production. In this embodiment, the first shell 2013 and the second shell 2014 are snap-fitted. It can be understood that in other embodiments not shown, the first shell 2013 and the second shell 2014 can also be connected by bolt connection, plug-in connection, magnetic connection and other detachable methods. It can be understood that in other embodiments not shown, the battery shell 201 can also be integrally formed.

[0135] A fixing plate 2015 is formed on the inner wall of the second shell 2014 along the radial extension of the battery shell 201, and an air guide column 2016 is protruded on the upper end surface of the fixing plate 2015 corresponding to the second through hole 301, and an air guide hole 2017 is opened on the air guide column 2016 along its own axial direction, and the air guide hole 2017 passes through the lower end surface of the fixing plate 2015. When the cigarette cartridge 100 is installed in place, the upper end of the air guide column 2016 is inserted into the second through hole 301 and the first through hole 501 in sequence, so that the air guide hole 2017 is connected to the lower end of the sensing chamber 115. In this embodiment, the fixing plate 2015 and the second shell 2014 are integrally formed. It can be understood that in other embodiments not shown, the fixing plate 2015 and the second shell 2014 can also be independent parts. When in use, the fixing plate 2015 and the second shell 2014 can be connected. In addition, the arrangement of the air guide column 2016 allows the cigarette cartridge 100 to be inserted into the battery assembly 200 in only one direction, otherwise, the cigarette cartridge 100 will be held by the air guide column 2016, making it impossible for the cigarette cartridge 100 to be inserted smoothly. When the cigarette cartridge 100 is inserted smoothly, the air guide column 2016 must be inserted into the second through hole 301 and the first through hole 501 in sequence, thereby ensuring that when the cigarette cartridge 100 is installed in place, the air guide hole 2017 must be connected to the sensing chamber 115. In addition, the plug-in design of the air guide column 2016 can improve the sealing performance.

[0136] In addition, a first magnetic member 2018 is installed on the upper end surface of the fixing plate 2015, and a second magnetic member 302 is installed on the lower end surface of the base 30. When the cigarette cartridge 100 is installed in place, the first magnetic member 2018 and the second magnetic member 302 can be attracted to each other, thereby ensuring that the cigarette cartridge 100 and the battery assembly 200 are not easily separated. It can be understood that in other embodiments not shown, the cigarette cartridge 100 and the battery assembly 200 can also be connected in a detachable manner such as threaded connection, clamping, etc., which is not limited here.

[0137] The control board 202 is accommodated in the accommodating cavity 2011 and is located below the fixing plate 2015. The battery 203 is installed in the accommodating cavity 2011 and is located below the control board 202. The upper end of the control board 202 is installed with a first terminal 2021 and a second terminal 2022. The upper end of the first terminal 2021 and the upper end of the second terminal 2022 both penetrate the fixing plate 2015, wherein the first terminal 2021 is electrically connected to one of the positive and negative electrodes of the battery 203, and the second terminal 2022 is electrically connected to the other of the positive and negative electrodes of the battery 203. When the cigarette cartridge 100 and the battery assembly 200 are installed in place, the first terminal 2021 contacts and is electrically connected to the first electrode 60, and the second terminal 2022 contacts and is electrically connected to the second electrode 70, thereby enabling the battery assembly 200 to electrically drive the heating element 22.

[0138] In addition, a partition 205 is also installed on the upper end surface of the fixed plate 2015, and the upper ends of the first terminal 2021 and the second terminal 2022 both penetrate the partition 205, and the air guide column 2016 passes through the through hole on the partition 205 and is inserted into the second through hole 301 and the first through hole 501 in sequence. The setting of the partition 205 shields the control board 202, the battery 203 and the first magnetic attraction member 2018 located below the partition 205, which not only makes the battery assembly 200 more beautiful, but also improves the safety of the battery assembly 200. The first magnetic attraction member 2018 is sandwiched between the partition 205 and the fixed plate 2015, so that the installation of the first magnetic attraction member 2018 is more reliable. The thickness of the partition 205 is appropriate, so it does not affect the magnetic attraction of the first magnetic attraction member 2018 to the second magnetic attraction member 302.

[0139] See also Figure 6-Figure 8The control board 202 is provided with an airtight member 206, which includes a longitudinal connection block 2061 and a transverse connection block 2062 connected to each other. The longitudinal connection block 2061 is arranged along the axial direction of the electronic cigarette, and the transverse connection block 2062 is arranged along the radial direction of the electronic cigarette, and one end of the transverse connection block 2062 is connected to one end of the longitudinal connection block 2061, so that the airtight member 206 is roughly in an inverted "L" shape. The connection between the longitudinal connection block 2061 and the transverse connection block 2062 forms a right angle structure (not shown in the figure), so that the airtight member 206 is hung on the upper end of the control board 202, and one of the side surfaces of the control board 202 is in contact with one of the surfaces of the longitudinal connection block 2061. At the same time, a mounting groove 2063 communicating with the air guide hole 2017 is provided on the lower end surface of the fixing plate 2015 corresponding to the air guide hole 2017, and one end of the transverse connecting block 2062 away from the longitudinal connecting block 2061 cooperates with the mounting groove 2063 and can be inserted into the mounting groove 2063. It can be understood that the transverse connecting block 2062 is connected to the mounting groove 2063, which limits the activity trend of the airtight member 206 along the longitudinal direction of the electronic cigarette, and the longitudinal connecting block 2061 is connected to the control board 202, which limits the activity trend of the airtight member 206 along the radial direction of the electronic cigarette, thereby limiting the position of the airtight member 206, and achieving the function of fixing the airtight member 206. It should be noted that one end of the transverse connecting block 2062 away from the longitudinal connecting block 2061 is arranged close to the second shell 2014, and the surface of the longitudinal connecting block 2061 away from the transverse connecting block 2062 is arranged close to the first shell 2013.

[0140] The surface of the longitudinal connection block 2061 close to the first shell 2013 is concave to form an opening 2064, the surface of the longitudinal connection block 2061 that fits the control board 202 is concave to form a mounting opening 2065, and the top of the transverse connection block 2062 is concave downward to form a connecting opening 2066, wherein the control board 202 closes the mounting opening 2065, the end of the mounting opening 2065 away from the control board 202 is connected to the opening 2064, and the connecting opening 2066 is connected to the opening 2064. In addition, please refer to Fig. 9, a cover plate 2067 is provided on the first shell 2013 corresponding to the opening 2064. When the first shell 2013 and the second shell 2014 are installed in place, the cover plate 2067 can cover the opening 2064 and close the opening 2064, thereby making the installation port 2065, the connecting port 2066 and the opening 2064 constitute a connecting channel with only one end opening (not marked in the figure). Specifically, the connecting port 2066 is the open end of the connecting channel. Among them, the installation port 2065, the opening 2064, the connecting port 2066 and the sensing chamber 115 together constitute (not marked in the figure). In this embodiment, the airtight member 206 is an integrated molding structure, and the airtight member 206 is made of silicone or rubber material to improve airtightness and prevent airflow leakage. The outer surface of one end of the transverse connecting block 2062 away from the longitudinal connecting block 2061 is sealed against the groove wall of the mounting groove 2063 , and the connecting port 2066 is aligned and connected with the air guide hole 2017 .

[0141] 10. The electronic cigarette of the present invention also includes a first air pressure detection component 207 and a second air pressure detection component 208 installed on the control board 202. The first air pressure detection component 207, the second air pressure detection component 208 and the battery 203 are all electrically connected to the control board 202. The first air pressure detection component 207 is installed in the sensing channel and is connected to the sensing channel. Specifically, in this embodiment, the mounting end of the first air pressure detection component 207 is installed on the control board 202, and the detection end of the first air pressure detection component 207 is installed in the mounting port 2065 and is connected to the sensing channel for detecting the air pressure value p1 in the sensing channel. The second air pressure detection component 208 is arranged on the control board 202 and is located outside the sensing channel, and is connected to the external atmosphere, and is used to detect the air pressure value p2 of the atmospheric pressure of the current environment of the electronic cigarette. It can be understood that in other embodiments not shown, the second air pressure detection component 208 can also be omitted. For example, a memory is provided on the control board 202, and the memory stores the air pressure value p2 of the atmospheric pressure; for another example, a receiver is provided on the control board 202, and the receiver is used to receive the air pressure value p2 of the atmospheric pressure sent by an external device.

[0142] It can be understood that in other embodiments not shown, the airtight part 206 can also be omitted. In this case, the upper end of the sensing chamber 115 passes through the upper end surface of the cigarette cartridge housing 11, and the lower end of the sensing chamber 115 is closed. The sensing channel is composed of the sensing chamber 115, and the first air pressure detection part 207 is installed in the sensing chamber 115 and is connected to the sensing chamber 115.

[0143] It can be understood that in other embodiments not shown, when the opening 2064 does not penetrate the surface of the longitudinal connecting block 2061, the cover plate 2067 can be omitted.

[0144] In this embodiment, the battery assembly 200 includes a USB socket 209 provided on the control board 202, and a USB connection port (not shown) is provided on the second housing 2014 corresponding to the USB socket 209. On one hand, the user uses a USB data cable to connect an external power source for charging or connect an external smart device for data exchange through the USB connection port and the USB socket 209; on the other hand, the second air pressure detection member 208 is connected to the outside atmosphere through the USB connection port and the USB socket 209. It can be understood that in other embodiments not shown, a connection port can also be directly provided on the battery housing 201, so that the second air pressure detection member 208 is connected to the outside atmosphere through the connection port.

[0145] In this embodiment, the mouthpiece 40 is only connected to the sensing channel and the airflow channel, and is not connected to the second air pressure detection component 208, and is separated by the partition 205, the base 30, etc. Therefore, the position of the second air pressure detection component 208 in the electronic cigarette is not connected to the mouthpiece 40. When inhaling, the airflow generated by the inhalation cannot be detected by the second air pressure detection component 208, so as to ensure that the second air pressure detection component 208 accurately detects the atmospheric pressure value and is not affected by the user's inhalation at the mouthpiece 40.

[0146] When in use, the control board 204 can execute the control method described in the first embodiment, and automatically control the output power of the battery 203 according to the difference between p1 and p2.

[0147] Specifically, when the electronic cigarette is not working, the first air pressure detection component 207 obtains p1, the second air pressure detection component 208 obtains p2, and the difference s between p1 and p2 is calculated. The difference s is used for air pressure calibration during inhalation to avoid inaccurate air pressure difference due to factors of the air pressure detection component itself.

[0148] When the user inhales, the difference s is subtracted from the difference between p1 and p2 to obtain the actual pressure difference K, so as to measure the current inhalation strength of the user.

[0149] The control panel 204 is preset with a start threshold A and an upper threshold B. When K=A, it is determined that suction is possible to avoid false triggering, and the initial power W1+C is output. When K>B, the maximum power W2 is output. When K>A and K<B, the output power is automatically adjusted according to the pressure difference K. At this time, the output power .

[0150] Wherein, W3 is the output power of the atomizer head, W1 is the first value, W2 is the second value, A is the start threshold, B is the upper limit threshold, K is the difference between the air pressure value p1 in the sensing channel detected by the first air pressure detection component and the air pressure value p2 of the atmospheric pressure of the electronic cigarette environment detected by the second air pressure detection component, or the difference after air pressure calibration, m is not zero and is a constant, and C is a constant; the first value is greater than or equal to the minimum value of the output power of the electronic cigarette that can atomize the smoke liquid, the second value is less than or equal to the maximum value of the output power supported by the electronic cigarette, and the second value is greater than the first value. In addition, the output power W3 of the atomizer head satisfies: W1≤W3≤W2.

[0151] In this embodiment, the first air pressure detection member 207 and the second air pressure detection member 208 are both air pressure sensors. The control board 204 is also equipped with a USB socket 209, the opening end of which is exposed to the outside of the battery shell 201. On the one hand, it is used to charge the battery 203, and on the other hand, the interior of the battery assembly 200 is connected to the outside atmosphere through the USB socket 209, so that the interior of the battery assembly 200 maintains normal pressure.

[0152] The electronic cigarette provided by the present invention obtains the air pressure value p1 in the sensing channel and the air pressure value p2 of the current environment respectively to obtain the user's suction force. Therefore, the power supply component 200 can realize the output power adjustment function through different suction forces, so that the user can obtain different smoking tastes and meet the usage needs of different users.

[0153] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the scope of the present invention through the above description. The technical scope of this invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
