[0034] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0035] The electronic atomization device is used to atomize the aerosol-generating matrix, which can be used in different fields, such as medical atomization, cosmetic atomization, and leisure smoking. Among them, the electronic atomization device is usually provided with a liquid storage space and an atomization component. The liquid storage space stores the aerosol-generating matrix, which can be a medicinal liquid, a nutrient solution or other combined liquid matrix with a special aroma. The atomization component is used to atomize the aerosol-generating matrix to generate an aerosol when the electronic atomization device is working. The atomization method of the atomization component can be heating atomization or non-heating atomization, wherein heating atomization includes resistance heating, electromagnetic heating, laser heating, infrared heating and microwave heating, etc.; non-heating atomization includes ultrasonic atomization, pressure atomization, mechanical vibration atomization and compressed air atomization, etc. However, the traditional single-liquid-cavity electronic atomization device, that is, the electronic atomization device is only provided with one liquid storage space. The liquid storage space of the atomization component is easily affected by the content of the aerosol-generating matrix in the liquid storage space, resulting in uneven liquid supply to the atomization component. Moreover, when the electronic atomization device is idle for a long time or the external atmospheric pressure changes, the aerosol-generating matrix in the liquid storage space is prone to leakage.

[0036] In order to solve the problems of liquid leakage and uneven liquid supply in traditional electronic atomization devices, see Figure 1-Figure 3 , Figure 1 This is a schematic structural diagram of an embodiment of the electronic atomization device provided by the present application; Figure 2 Yes Figure 1 A cross-sectional view of the electronic atomization device along line AA; Figure 3 It is a cross-sectional view of another embodiment of the electronic atomization device provided in this application.

[0037] The electronic atomization device 100 provided in this application includes a liquid supply chamber 11, a liquid storage chamber 12, a sensing hole 13, a first sensing element 14, a liquid supply mechanism 20, and a control device 30. The first sensing element 14 detects a current pressure value P1 within the liquid supply chamber 11 through the sensing hole 13. The liquid supply mechanism 20 is used to drive the liquid within the liquid storage chamber 12 to supply liquid to the liquid supply chamber 11. The control device 30 is electrically connected to the liquid supply mechanism 20 and the first sensing element 14. The control device 30 controls the liquid supply mechanism 20 based on a difference D1 between the current pressure value P1 and a preset pressure value P0, thereby driving the liquid within the liquid storage chamber 12 to supply liquid to the liquid supply chamber 11.

[0038] Specifically, when the atomizing assembly 10 atomizes the aerosol generating matrix in the liquid supply chamber 11, as the aerosol generating matrix in the liquid supply chamber 11 is gradually consumed, the pressure value in the liquid supply chamber 11 will also decrease. The first sensing element 14 detects the current pressure value P1 of the liquid supply chamber 11 through the sensing hole 13. The control device 30 compares the current pressure value P1 detected by the first sensing element 14 with the preset pressure value P0. If the difference D1 between the current pressure value P1 and the preset pressure value P0 is not within the preset range, the control device 30 controls the liquid supply mechanism 20 to drive the liquid storage chamber 12 to move forward. The liquid is supplied to the liquid supply chamber 11, thereby ensuring that the pressure in the liquid supply chamber 11 is always maintained within the preset pressure range, realizing the liquid supply effect of ready-to-use, effectively controlling the liquid supply to the atomizer assembly 10, ensuring uniform liquid supply, and the liquid supply chamber 11 and the liquid storage chamber 12 are designed with dual liquid chambers. The control device 30 controls the liquid supply mechanism 20 to drive the liquid in the liquid storage chamber 12 to supply the liquid to the liquid supply chamber 11 based on the difference D1 between the current pressure value P1 in the liquid supply chamber 11 and the preset pressure value P0, which solves the problem that the traditional single liquid chamber is easily affected by the external atmospheric pressure, resulting in liquid leakage and uneven liquid supply.

[0039] Among them, the first sensing element 14 can be an air pressure sensor. The air pressure sensor is sealed at one end of the sensing hole 13 away from the liquid supply chamber 11, and the other end of the sensing hole 13 is sealed by the aerosol generating matrix in the liquid supply chamber 11 to form an air column in the sensing hole 13. Specifically, the air pressure sensor is connected to the liquid supply chamber 11 through the sensing hole 13, and when the length and diameter of the sensing hole 13 are appropriate, a section of air column will be formed in the sensing hole 13 to isolate the air pressure sensor from the liquid supply chamber 11. When the pressure in the liquid supply chamber 11 changes, for example, when the sol generating matrix in the liquid supply chamber 11 increases or decreases, or when the external atmospheric pressure changes, the pressure of this section of air column will change accordingly. The air pressure sensor is more sensitive to air changes than to liquids, which can improve the sensitivity of detecting air pressure changes in the liquid supply chamber 11 and achieve accurate liquid supply.

[0040] Among them, the cross-section of the sensing hole 13 can be circular, elliptical, rectangular, etc., and the cross-sectional dimension of the sensing hole 13 along the diameter direction is less than or equal to 5.0 mm. Specifically, if the aperture of the sensing hole 13 is too small, the air in the air column will easily dissolve into the aerosol generating matrix, and thus the air column cannot be formed. If the aperture of the sensing hole 13 is too large, the air in the air column will easily squeeze into the liquid supply cavity 11, and the air column cannot be formed. Only when the aperture and length of the sensing hole 13 are appropriate to achieve a balance will an air column be formed, and the length of the air column will change with the change of the pressure in the liquid supply cavity 11. The air pressure sensor detects the pressure in the liquid supply cavity 11 through the pressure change of the air column.

[0041] In one embodiment, the cross section of the sensing hole 13 along the diameter direction is a circular hole, and the diameter of the circular hole is greater than or equal to 0.3 mm and less than or equal to 5.0 mm. For example, the diameter of the circular hole is 0.3 mm, 2.0 mm, 4.0 mm, or 5.0 mm.

[0042] In one embodiment, see Figure 2 Considering the airtightness and liquid tightness of the sensing hole 13, the sensing hole 13 is set on the side wall of the liquid supply chamber 11. The length of the sensing hole 13 is greater than or equal to 1.0 mm and less than or equal to 50 mm. The specific setting can be based on the aperture of the sensing hole 13 so that the diameter and length of the sensing hole 13 are appropriate to form an air column.

[0043] Of course, the sensing hole 13 can also be set at any position on the electronic atomization device, as long as one end of the sensing hole 13 is covered by the first sensing element 14 and the other end is sealed by the aerosol generating matrix liquid in the liquid supply cavity 11.

[0044] The first sensing element 14 may also be a hydraulic sensor, and the aerosol-generating substrate in the liquid supply chamber 11 contacts the hydraulic sensor through the sensing hole 13. When the first sensing element 14 is a hydraulic sensor, the diameter, length, and location of the sensing hole 13 are not limited, as long as the aerosol-generating substrate in the liquid supply chamber 11 can directly contact the hydraulic sensor through the sensing hole 13 and leakage of the aerosol-generating substrate from the sensing hole 13 is prevented.

[0045] It should be noted that since the hydraulic sensor detects pressure through direct contact with the liquid, there is another advantage when the first sensing element 14 is a hydraulic sensor. The sensing hole 13 does not need to be set in the electronic atomization device. The hydraulic sensor is directly set in the liquid supply chamber 11, eliminating the process of drilling a sensing hole for the electronic atomization device and further preventing leakage.

[0046] Specifically, when the user inhales the electronic atomization device 100, the airflow in the electronic atomization device 100 will change. The electronic atomization device 100 is also provided with an airflow sensing component 53. The airflow sensing component 53 can be a frequency silicon microphone or a microphone head, which is used to detect the change of airflow in the electronic atomization device 100. The airflow sensing component 53 is electrically connected to the control device 30. The control device 30 detects the change of airflow in the electronic atomization device 100 based on the airflow sensing component 53, judges that the user triggers the suction trigger signal, controls the atomization component 10 to atomize the aerosol to generate the matrix, and controls the first sensing element 14 to detect the current pressure value P1 in the liquid supply chamber.

[0047] The preset pressure value P0 can be the current pressure value P1 of the liquid supply chamber 11 detected by the first sensing element 14 when the user just triggers the inhalation trigger signal. Alternatively, the preset pressure value P0 can be the pressure value within the liquid supply chamber 11 detected by the first sensing element 14 when the electronic atomization device 100 is idle, that is, before the electronic atomization device atomizes. Alternatively, the preset pressure value P0 can be a value pre-set in the control device 30. Alternatively, the preset pressure value P0 can be the real-time detected external atmospheric pressure value P2.

[0048] In one embodiment, the upper surface of the atomizing assembly 10 is an atomizing surface, and the atomizing assembly 10 has micropores for introducing the aerosol-generating substrate in the liquid supply chamber 11 into the atomizing surface. The lower surface of the atomizer assembly 10 is in contact with the liquid supply chamber 11, and the upper surface of the atomizer assembly 10 is connected to the outside world. The pressure difference between the liquid supply chamber 11 and the upper surface of the atomizer assembly 10 will cause the aerosol-generating matrix to pass through the micropores in the atomizer assembly 10 to reach the upper surface, thereby reducing the pressure in the liquid supply chamber 11, and finally making the liquid supply chamber 11 reach equilibrium with the external atmospheric pressure value P2. Since in the idle stage of the electronic atomizer device 100, the pressure in the liquid supply chamber 11 will gradually tend to equilibrium with the external atmospheric pressure value P2 as time changes, therefore, the current pressure value P1 of the liquid supply chamber 11 detected by the first sensing element 14 when the user just triggers the inhalation trigger signal is used as the preset pressure value P0, or the pressure value of the liquid supply chamber 11 before atomization detected by the first sensing element 14 is used as the preset pressure value P0, which is equivalent to using the external atmospheric pressure value P2 as the preset pressure value P0.

[0049] It should be noted that it takes a certain amount of time for the pressure in the liquid supply chamber 11 to gradually reach equilibrium with the external atmospheric pressure value P2 as time changes. When the external atmospheric pressure changes, the pressure value in the liquid supply chamber 11 is not balanced with the actual external atmospheric pressure value in a short period of time. During this period of time, if the pressure value in the liquid supply chamber 11 is detected as the preset pressure value P0, it may cause leakage of the aerosol generating matrix in the liquid supply chamber 11 or insufficient liquid supply. For example, during this period of time, if the pressure value in the liquid supply chamber 11 is greater than the external atmospheric pressure value P2, the aerosol generating matrix in the liquid supply chamber 11 will be squeezed, and the aerosol generating matrix will pass through the micropores of the atomizing component 10 to reach the upper surface of the heating element, resulting in leakage. If the pressure value in the liquid supply chamber 11 is less than the external atmospheric pressure value P2, the aerosol generating matrix in the micropores of the atomizing component 10 will be caused to flow back to the liquid supply chamber 11, resulting in insufficient liquid supply to the atomizing component 10, causing the atomizing component 10 to dry burn and produce toxic and harmful gases.

[0050] Therefore, in a specific embodiment, the electronic atomization device 100 further includes a second sensing element (not shown), which is electrically connected to the control device 30 and is used to detect the external atmospheric pressure value P2, and the actual external atmospheric pressure value P2 is used as the preset pressure value P0.

[0051] Or in another specific embodiment, the second sensing element is not provided in the electronic atomization device 100, and the first sensing element 14 is also used to detect the external atmospheric pressure value P2. Specifically, before the electronic atomization device 100 is atomized, the first sensing element 14 detects the pressure value in the liquid supply chamber 11 and the external atmospheric pressure value P2, and simultaneously outputs the pressure value in the liquid supply chamber 11 and the external atmospheric pressure value P2 to the control device 30, or directly outputs the pressure difference D2 between the pressure value in the liquid supply chamber 11 and the external atmospheric pressure value P2 to the control device 30. Compared with the electronic atomization device 100 in which the first sensing element 14 and the second sensing element are provided, the electronic atomization device 100 provided in this embodiment has a lower cost.

[0052] It can be understood that there are three advantages to using the external atmospheric pressure value P2 as the preset pressure value P0. First, when the control device 30 is controlling, the difference D1 between the current pressure value P1 in the liquid supply chamber 11 and the external atmospheric pressure value P2 (preset pressure value P0) can be directly used for control, so that the control is more precise. Under the condition of only detecting the current pressure value P1 in the liquid supply chamber 11, it is necessary to record the pressure value in the liquid supply chamber 11 as the preset pressure value P0 when the current pressure value P1 in the liquid supply chamber 11 and the external atmospheric pressure value P2 reach equilibrium, which has the risk of misjudgment. Second, the external atmospheric pressure value P2 will change under different temperatures, altitudes, etc. By detecting the external atmospheric pressure value P2 in real time and Make corrections so that the pressure value in the liquid supply chamber 11 is always the same as the external atmospheric pressure value P2; thirdly, when the external atmospheric pressure value P2 changes, especially when the external atmospheric pressure value P2 becomes smaller, since the pressure value in the liquid supply chamber 11 is greater than the external atmospheric pressure value P2, the aerosol generating matrix will be squeezed, and the aerosol generating matrix will pass through the micropores of the atomizing component 10 to reach the upper surface of the heating element, resulting in leakage. The second sensing element can detect that the external atmospheric pressure value P2 becomes smaller, and the liquid supply mechanism is used to control the pressure in the liquid supply chamber 11 before atomization, so that the pressure value in the liquid supply chamber 11 reaches a new balance with the external atmospheric pressure value P2, thereby preventing liquid leakage and insufficient liquid supply.

[0053] In one scenario, the control device 30 compares the detected pressure value in the liquid supply chamber 11 with the detected external atmospheric pressure value P2. In response to the pressure difference D2 between the pressure value of the liquid supply chamber 11 before atomization and the external atmospheric pressure value P2 being outside the preset range, for example, the user carries the electronic atomization device 100 and moves from a high altitude to a low altitude, resulting in the pressure value in the liquid supply chamber 11 being less than the external atmospheric pressure value P2 and the pressure difference D2 being outside the preset range. At this time, the control device 30 controls the liquid supply mechanism 20 to operate to drive the aerosol generating matrix in the liquid storage chamber 12 to supply liquid to the liquid supply chamber 11, so that the pressure value in the liquid supply chamber 11 is balanced with the external atmospheric pressure value P2. In response to the pressure difference D2 between the pressure value of the liquid supply chamber 11 before atomization and the preset pressure value being within the preset range, the control device 30 controls the liquid supply mechanism 20 to shut down.

[0054] In another scenario, the control device 30 compares the detected pressure value in the liquid supply chamber 11 with the detected external atmospheric pressure value P2, and in response to the pressure difference D2 between the pressure value of the liquid supply chamber 11 before atomization and the external atmospheric pressure value P2 being outside the preset range, for example, the user carries the electronic atomization device 100 and moves from a low altitude to a high altitude, resulting in the pressure value in the liquid supply chamber 11 being greater than the external atmospheric pressure value P2 and the pressure difference D2 being outside the preset range. At this time, the control device 30 controls the liquid supply mechanism 20 to operate to drive the aerosol-generating matrix in the liquid supply chamber 11 to guide liquid to the liquid storage chamber 12, so that the pressure value in the liquid supply chamber 11 is balanced with the external atmospheric pressure value P2. In response to the pressure difference D2 between the pressure value of the liquid supply chamber 11 before atomization and the preset pressure value being within the preset range, the control device 30 controls the liquid supply mechanism 20 to shut down.

[0055] In one embodiment, see Figure 3 The electronic atomization device 100 also includes an installation cavity 51, in which the first sensing element 14 and the control device 30 are arranged. One end of the sensing hole 13 is connected to the liquid supply cavity 11, and the end of the sensing hole 13 away from the liquid supply cavity 11 is also connected to the installation cavity 51. The first sensing element 14 is sealed at the end of the sensing hole 13 away from the liquid supply cavity 11.

[0056] The first sensing element 14 can be disposed on a sidewall of the mounting cavity 51 and electrically connected to the control device 30 within the mounting cavity 51 via a wire. The first sensing element 14 and the control device 30 can also be integrated into one body, thereby reducing wiring and further reducing problems such as short circuits and open circuits caused by circuit connections, thereby ensuring a safe and reliable electrical connection between the first sensing element 14 and the control device 30.

[0057] In one embodiment, see Figure 5 , Figure 5 Yes Figure 2The electronic atomization device 100 includes a nozzle assembly 40, an atomizer assembly 10, and a housing 50. The atomizer assembly 10 is connected to the nozzle assembly 40, and the nozzle assembly 40 and the atomizer assembly 10 cooperate to define a liquid supply chamber 11. The atomizer assembly 10 is used to draw liquid from the liquid supply chamber 11 and perform heated or non-heated atomization. The housing 50 is connected to the nozzle assembly 40 and has a mounting cavity 51.

[0058] Among them, the shell 50 and the suction nozzle assembly 40 can be integrally formed or detachably connected, the liquid storage chamber 12 can be set on the suction nozzle assembly 40 or on the shell 50, and the liquid storage chamber 12 can also be partially set on the suction nozzle assembly 40 and partially set on the shell 50. The specific selection can be made according to actual needs.

[0059] In one embodiment, see Figure 3 The first sensing element 14 is arranged on the shell 50, and the sensing hole 13 includes a first hole section 131 arranged on the suction nozzle assembly 40 and a second hole section 132 arranged on the shell 50. The first sensing element 14 is sealed at one end of the second hole section 132 facing the installation cavity 51.

[0060] In this embodiment, considering the airtightness and liquidtightness of the sensing hole 13, the housing 50 and the nozzle assembly 40 are integrally formed to avoid a gap between the housing 50 and the nozzle assembly 40 that could cause liquid leakage.

[0061] In this embodiment, if cost issues are taken into consideration, the shell 50 and the suction nozzle assembly 40 can be provided with a detachable connection. Since the first sensing element 14 is provided in the shell 50 and is separated from the suction nozzle assembly 40, when the suction nozzle assembly 40 is replaced, the first sensing element 14 does not need to be replaced, and the first sensing element 14 can be reused, thereby reducing costs.

[0062] In one embodiment, see Figure 3 and Figure 5 The nozzle assembly 40 includes a nozzle 41 and a base 42. The nozzle 41, the atomizer assembly 10, and the base 42 define a liquid supply chamber 11. Specifically, the atomizer assembly 10 is connected to and held by the nozzle 41. The nozzle 41 is also provided with an atomization channel 4110 for discharging aerosol. The atomization surface of the atomizer assembly 10 faces the atomization channel 4110. The base 42 is provided at one end of the nozzle 41 near the housing 50. The nozzle 41 and the base 42 are also used to connect to the housing 50.

[0063] Specifically, the nozzle 41 constitutes the side wall of the liquid supply chamber 11, the base 42 constitutes the bottom wall of the liquid supply chamber 11, and the atomizer assembly 10 constitutes the top wall of the liquid supply chamber 11 and is used to atomize the aerosol-generating matrix in the liquid supply chamber 11. When the first sensing element 14 is disposed on the side wall of the liquid supply chamber 11 (see Figure 5), the sensing hole 13 is completely set on the side wall of the nozzle 41. When the first sensing element 14 is set in the installation cavity 51 (see Figure 3 ), the sensing hole 13 includes a first hole section 131 located on the suction nozzle 41 and a second hole section 132 located on the shell. One end of the first hole section 131 is connected to the liquid supply chamber 11, and the other end is connected to the second hole section 132 formed on the shell 50.

[0064] In one embodiment, please combine Figure 6 , Figure 6 Yes Figure 1 An exploded view of the structure of the nozzle assembly in the electronic atomization device is shown. The first sensing element 14 is disposed on the side wall of the liquid supply chamber 11. The outer surface of the side wall of the liquid supply chamber 11 is also provided with a mounting groove 4120. The first sensing element 14 is disposed in the mounting groove 4120. One end of the sensing hole 13 is connected to the liquid supply chamber 11, and the other end is located at the bottom wall of the mounting groove 4120 and is covered by the first sensing element 14. Specifically, the first sensing element 14 is disposed in the mounting groove 4120. On the one hand, it can prevent external forces from acting on the first sensing element 14, causing the first sensing element 14 to fall off or be damaged; on the other hand, it can make the electronic atomization device 100 have an aesthetically pleasing appearance.

[0065] In which, when the suction nozzle assembly 40 is detachably connected to the shell 50, a connecting structure is provided on both the base 42 and the shell 50, and the base 42 and the shell 50 are connected via the connecting structure. For example, a protrusion is provided on the end of the base 42 close to the shell 50, and a groove is provided on the end of the shell 50 close to the base 42, and the suction nozzle assembly 40 and the shell 50 are connected by snapping the protrusion and the groove. For example, a positive thread is provided on the end of the base 42 close to the shell 50, and a reverse thread is provided on the end of the shell 50 close to the base 42, and the suction nozzle assembly 40 and the shell 50 are connected via threads. Of course, it is also possible that the suction nozzle 41 and the shell 50 are both provided with a connecting structure, and no connecting structure is provided on the base 42, and the specific selection can be made according to actual conditions.

[0066] In one embodiment, the liquid storage chamber 12 is disposed on the housing 50, and the base 42 is configured to connect the liquid storage chamber 12 and the liquid supply chamber 11 when the nozzle assembly 40 is connected to the housing 50, and to seal the liquid supply chamber 11 when the nozzle assembly 40 is separated from the housing 50. Specifically, when the liquid storage chamber 12 is disposed in the mounting cavity 51, in order to prevent the aerosol-generating substrate in the liquid supply chamber 11 from flowing out of the liquid supply chamber 11 due to separation of the housing 50 and the nozzle assembly 40, for example, when the nozzle assembly 40 is connected to the housing 50, the liquid storage chamber 12 is connected to the liquid supply chamber 11 via the base 42, thereby not affecting the liquid supply mechanism 20 driving the liquid in the liquid storage chamber 12 to supply the liquid to the liquid supply chamber 11. In the scenario of replacing the disposable nozzle assembly 40 or filling the liquid storage chamber 12, when the nozzle assembly 40 is separated from the housing 50, the base seals the liquid supply chamber 11, thereby preventing the aerosol-generating substrate in the liquid supply chamber 11 from flowing out of the liquid supply chamber 11, which would cause waste and hygiene problems. It can be understood that the base 42 acts as a one-way valve, and the aerosol generating substrate can only flow into the liquid supply chamber 11 but cannot flow out.

[0067] In one embodiment, see Figure 6 and Figure 7 , Figure 7 Yes Figure 6 The exploded view of the structure of the base is shown. The base 42 includes an end cover 421 and a closure member 422. The end cover 421 is provided with a liquid hole 4210 connected to the liquid supply chamber 11 and is connected to the suction nozzle 41. The closure member 422 is provided on the end cover 421 and is provided with a closing slit 4220 corresponding to the position of the liquid hole 4210. The closing slit 4220 closes the liquid hole 4210 when the suction nozzle assembly 40 is separated from the shell 50, and allows the liquid storage chamber 12 and the liquid supply chamber 11 to be connected when the suction nozzle assembly 40 is connected to the shell 50. Specifically, the end cover 421 includes a bottom plate 4211 and an annular flange 4212. The bottom plate 4211 is used to connect to the shell 50, and the bottom plate 4211 and the annular flange 4212 define a receiving groove 4213. The closure member 422 is provided in the receiving groove 4213. The liquid hole 4210 is provided at a position on the bottom plate 4211 corresponding to the closing slit 4220, and the sealing member 422 can be made of an elastic material such as silicone or rubber. It is understood that when the liquid storage chamber 12 is provided in the mounting cavity 51 and the housing 50 is connected to the nozzle assembly 40, due to the elasticity of the closing slit 4220, a portion of the liquid storage chamber 12 can pass through the liquid hole 4210 and the closing slit 4220, compressing the sealing member 422 to communicate with the liquid supply chamber 11. When the housing 50 is separated from the nozzle assembly 40, the liquid storage chamber 12 is disengaged from the closing slit 4220 and the liquid hole 4210, and the sealing member 422 is restored, thereby sealing the closing slit 4220 and achieving the purpose of sealing the liquid supply chamber 11.

[0068] In another embodiment, an electric baffle (not shown) can be provided on the base 42, and the electric baffle is electrically connected to the control device 30. When the suction nozzle assembly 40 is connected to the shell 50, the control device 30 controls the movement of the electric baffle to separate the liquid storage chamber 12 and the liquid supply chamber 11. When the suction nozzle assembly 40 is separated from the shell 50, the control device 30 controls the movement of the electric baffle to close the liquid supply chamber 11.

[0069] In one embodiment, see Figure 5 and Figure 6 The nozzle 41 includes a nozzle holder 411 and a heating seat 412. The nozzle holder 411 is disposed at the end of the heating seat 412 facing away from the base 42. The nozzle holder 411 is provided with an atomization channel 4110; the heating seat 412 is provided with a mounting groove 4120. The heating seat 412 is connected to the nozzle holder 411 to clamp the atomization assembly 10. In this embodiment, the nozzle 41 is divided into the nozzle holder 411 and the heating seat 412. The user can replace the nozzle holder 411 according to hygiene and wear conditions without having to replace the entire nozzle 41, which is beneficial to health and reduces usage costs.

[0070] In this embodiment, a detection channel 52 is further provided on the electronic atomization device 100, and an airflow sensor 53 is connected to one end of the detection channel 52 away from the atomization channel 4110. Specifically, one end of the detection channel 52 is connected to the atomization channel 4110, and the other end is covered by the airflow sensor 53. When the user inhales the electronic atomization device 100, the airflow in the atomization channel 4110 changes. For example, when the air pressure in the atomization channel 4110 becomes negative pressure, the airflow sensor 53 detects the airflow change in the atomization channel 4110 through the detection channel 52. The control device 30 controls the operation of the atomization assembly 10, the first sensing element 14 and the second sensing element based on the airflow change detected by the airflow sensor 53. Among them, the airflow sensor can be provided on the nozzle assembly 40, and can also be provided on the shell 50.

[0071] See also Figure 4 , Figure 4 Yes Figure 1 The electronic atomization device is shown in a cross-sectional view along line BB. The airflow sensor 53 is provided on the housing 50, and the detection channel 52 includes a first detection section 521 and a second detection section 522. The first detection section 521 is provided on the heating seat 412, and the second detection section 522 is provided on the housing 50. One end of the first detection section 521 is connected to the atomization channel 4110, and the other end of the first detection section 521 is connected to one end of the second detection section 522 on the housing 50. The other end of the second detection section 522 is covered by the airflow sensor 53. Specifically, the airflow sensor 53 is provided on the housing, for example, provided on the housing and integrated with the control device, which can reduce wiring and make the electrical connection between the airflow sensor 53 and the control device 30 safe and reliable.

[0072] In one embodiment, see Figure 8 , Figure 8 This is a cross-sectional view of another embodiment of the electronic atomization device provided by the present application. A liquid storage chamber 12 is provided at one end of the housing 50 facing the nozzle assembly 40. Specifically, the housing 50 includes a sidewall 54 and a partition wall 55. The partition wall 55 is disposed within the chamber enclosed by the sidewall 54 and separates the chamber into a mounting chamber 51 and a receiving chamber 56. The receiving chamber 56 is disposed adjacent to the nozzle assembly 40 and serves as the liquid storage chamber 12.

[0073] In another embodiment, see Figure 2 and Figure 9 , Figure 9 It is a structural diagram of an embodiment of the connection between the liquid supply mechanism and the oil bottle provided in the present application. The electronic atomization device 100 also includes a liquid bottle 57, which is arranged on the shell 50, and the liquid bottle 57 is provided with a liquid storage chamber 12. Specifically, the liquid bottle 57 is arranged in the receiving chamber 56, and the liquid bottle 57 has a liquid storage chamber 12 for storing the aerosol generating matrix. Specifically, the liquid bottle 57 includes a bottle body 571 and a bottle mouth 572, the bottle body 571 is arranged in the receiving chamber 56, and the bottle mouth 572 is used to pass through the suction nozzle assembly 40 to communicate with the liquid supply chamber 11 when the shell 50 is connected to the suction nozzle assembly 40. In this embodiment, a limiting structure is provided on the liquid bottle 57 and the shell 50, which is used to fix the liquid bottle 57 on the shell 50. For example, one of the liquid bottle 57 and the housing 50 is provided with a limiting protrusion, and the other is provided with a limiting groove. When the liquid bottle 57 is placed in the receiving cavity 56, the limiting protrusion is fixed in the limiting groove, thereby fixing the liquid bottle 57 to the housing 50. The liquid bottle 57 is fixed to the housing 50 by the limiting structure, which is convenient for removal, allowing the user to freely fill the liquid bottle 57 with liquid, realize repeated use, and help reduce user costs.

[0074] In one embodiment, please continue to see Figure 9 The liquid supply mechanism 20 includes a piston 21 and a driving member 22. The piston 21 is movably disposed in the liquid storage chamber 12. The output end of the driving member 22 is connected to the piston 21 and is electrically connected to the control device 30, and is used to drive the piston 21 to move along the side wall of the liquid storage chamber to supply liquid to the liquid supply chamber 11. The driving member 22 includes a power source such as a motor 221, a peristaltic pump, or a compression pump. In this embodiment, the piston 21 assembly is located in the liquid storage chamber 12 and at the bottom of the aerosol-generating matrix. Under the drive of the driving member 22, it is used to push the aerosol-generating matrix thereon to supply liquid to the liquid supply chamber 11.

[0075] In this embodiment, the driving member 22 includes a motor 221 and a push rod 222. One end of the push rod 222 is connected to the output end of the motor 221, and the other end is connected to the piston 21. When the motor 221 is working, the push rod 222 drives the piston 21 to push the aerosol generating matrix in the liquid storage chamber 12 into the liquid supply chamber 11.

[0076] Please continue to see Figure 5 To optimize the product design, the atomizer assembly 10, the liquid supply chamber 11, the liquid storage chamber 12, and the liquid supply mechanism 20 are arranged in series. When the liquid supply mechanism 20 is working, the driving member 22 controls the piston 21 to move toward the liquid supply chamber 11 to inject the aerosol-generating matrix in the liquid storage chamber 12 into the liquid supply chamber 11.

[0077] The electronic atomization device provided in the present application is a dual-liquid chamber design of a liquid supply chamber 11 and a liquid storage chamber 12. The control device 30 compares the current pressure value P1 detected by the first sensing element 14 with the preset pressure value P0. If the difference D1 between the current pressure value P1 and the preset pressure value P0 is not within the preset range, the control device 30 controls the liquid supply mechanism 20 to drive the liquid in the liquid storage chamber 12 to supply liquid to the liquid supply chamber 11, thereby ensuring that the pressure in the liquid supply chamber 11 is always maintained within the preset pressure range, achieving a ready-to-use liquid supply effect, effectively controlling the liquid supply to the atomization component 10, and ensuring uniform liquid supply. The liquid supply chamber 11 and the liquid storage chamber 12 are designed with dual liquid chambers. The control device 30 controls the liquid supply mechanism 20 to drive the liquid in the liquid storage chamber 12 to supply liquid to the liquid supply chamber 11 based on the difference D1 between the current pressure value P1 and the preset pressure value P0 in the liquid supply chamber, solving the problem that the traditional single liquid chamber is easily affected by the external atmospheric pressure, resulting in liquid leakage and uneven liquid supply.

[0078] In order to solve the problems of liquid leakage and uneven liquid supply in traditional electronic atomization devices, see Figure 10 , Figure 10 1 is a flow chart of an embodiment of the automatic liquid supply method provided by the present application. The present application provides an automatic liquid supply method, comprising:

[0079] Step S1: Detect the current pressure value in the liquid supply chamber.

[0080] Specifically, the electronic atomization device includes an atomization component, a liquid supply chamber, and a first sensing element. The liquid supply chamber stores an aerosol generating matrix. The atomization component is used to atomize the aerosol generating matrix in the liquid supply chamber to generate an aerosol under power-on conditions. The first sensing element is used to detect the current pressure value P1 in the liquid supply chamber.

[0081] The first sensing element may be an air pressure sensor or a hydraulic pressure sensor, and the first sensing element is used to detect the air pressure value or the hydraulic pressure value in the liquid supply cavity.

[0082] In one embodiment, the first sensing element detects the current pressure value P1 in the liquid supply chamber in real time. For example, the first sensing element detects the current pressure value P1 in the liquid supply chamber both when the user is using the electronic atomization device and when the electronic atomization device is idle.

[0083] In another embodiment, the first sensing element is used to detect the current pressure value P1 in the liquid supply chamber during each atomization process, that is, the first sensing element detects the current pressure value P1 in the liquid supply chamber only when the user draws on the electronic atomization device.

[0084] Step S2: Based on the difference between the current pressure value and the preset pressure value, the liquid supply mechanism is controlled to operate, so as to drive the liquid in the liquid storage chamber to supply the liquid to the liquid supply chamber.

[0085] Specifically, the electronic atomization device also includes a liquid storage chamber, a liquid supply mechanism, and a control device. The liquid storage chamber stores an aerosol-generating matrix. The liquid supply mechanism is used to drive the aerosol-generating matrix in the liquid storage chamber to supply liquid to the liquid supply chamber. The control device is electrically connected to the liquid supply mechanism and the first sensing element. The control device detects the current pressure value P1 in the liquid supply chamber based on the first sensing element, and controls the liquid supply mechanism to drive the aerosol-generating matrix in the liquid storage chamber to supply liquid to the liquid supply chamber based on the difference D1 between the current pressure value P1 and the preset pressure value P0. Specifically, if the current pressure value P1 is less than the preset pressure value P0, and the difference D1 between the current pressure value P1 and the preset pressure value P0 is less than the preset limit, the control device controls the liquid supply mechanism to operate to drive the aerosol-generating matrix in the liquid storage chamber to supply liquid to the liquid supply chamber, thereby ensuring that the aerosol-generating matrix in the liquid supply chamber can maintain normal atomization of the atomization component.

[0086] It is understandable that when a user draws in the electronic atomization device, as the aerosol generating matrix in the liquid supply chamber is atomized and consumed by the atomization component, the pressure in the liquid supply chamber will decrease. When the pressure in the liquid supply chamber decreases to a certain extent, the aerosol generating matrix in the liquid supply chamber will not supply enough liquid to the atomization component, causing the atomization component to dry burn and produce toxic and harmful gases. The control device in the present application can control the liquid supply mechanism to drive the aerosol generating matrix in the liquid storage chamber to supply liquid to the liquid supply chamber based on the difference D1 between the current pressure value P1 and the preset pressure value P0 detected by the first sensing element, ensuring that the aerosol generating matrix in the liquid supply chamber normally supplies liquid to the atomization component, realizing the ready-to-use liquid supply effect of the electronic atomization device, and the pressure in the liquid supply chamber is always maintained within the preset pressure range, which can ensure the purpose of uniform liquid supply from the liquid supply chamber to the atomization component. In addition, the electronic atomization device is provided with a liquid supply chamber and a liquid storage chamber. The control device controls the liquid supply mechanism to drive the aerosol generating matrix in the liquid storage chamber to supply liquid to the liquid supply chamber based on the difference D1 between the current pressure value P1 and the preset pressure value P0. Compared with the single liquid chamber, the content of the aerosol generating matrix in the liquid supply chamber is less, which can reduce the leakage of the aerosol generating matrix through the atomization component.

[0087] Wherein, step S1 includes: detecting the current pressure value in the liquid supply chamber in response to a suction trigger signal; wherein the suction trigger signal is triggered when the user draws on the electronic atomization device.

[0088] Specifically, when a user inhales from the electronic atomization device, the airflow in the electronic atomization device will change. The electronic atomization device is also provided with an airflow sensing component, which can be a frequency silicon microphone or a microphone head, for detecting changes in the airflow in the electronic atomization device. The airflow sensing component is electrically connected to the control device. The control device detects changes in the airflow in the electronic atomization device based on the airflow sensing component, and controls the first sensing element to detect the current pressure value P1 in the liquid supply chamber.

[0089] The preset pressure value P0 may be the current pressure value P1 of the liquid supply chamber detected by the first sensing element when the user just triggers the inhalation trigger signal. Alternatively, the preset pressure value P0 may be the pressure value P3 of the liquid supply chamber detected by the first sensing element when the electronic atomizer device is idle, i.e., before the electronic atomizer device atomizes. Alternatively, the preset pressure value P0 may be a value pre-set in the control device. Alternatively, the preset pressure value P0 may be the external atmospheric pressure value P2 detected in real time.

[0090] In a specific embodiment, the control device detects the pressure value P3 of the liquid supply chamber before atomization through the first sensing element as the preset pressure value P0.

[0091] In another specific embodiment, the electronic atomization device further includes a second sensing element, which is used to detect an external atmospheric pressure value P2. The control device detects the external atmospheric pressure value P2 through the second sensing element as the preset pressure value P0.

[0092] Alternatively, in another specific embodiment, the second sensing element is not provided in the electronic atomization device, and the first sensing element is further used to detect the external atmospheric pressure value P2. Specifically, before the electronic atomization device atomizes, the first sensing element detects the pressure value P3 in the liquid supply chamber and the external atmospheric pressure value P2, and simultaneously outputs the pressure value P3 in the liquid supply chamber and the external atmospheric pressure value P2 to the control device, or directly outputs the pressure difference D2 between the pressure value P3 in the liquid supply chamber and the external atmospheric pressure value P2 to the control device.

[0093] For details, see Figure 11 , Figure 11 This is a flow chart of another embodiment of the automatic liquid supply method provided by the present application. In this embodiment, before step S1, the following steps are also included:

[0094] Step S01: In response to the pressure difference between the pressure value of the liquid supply chamber before atomization and the preset pressure value being within a non-preset range, the liquid supply mechanism is controlled to start to drive the liquid in the liquid storage chamber to supply the liquid to the liquid supply chamber, or to drive the liquid in the liquid supply chamber to guide the liquid to the liquid storage chamber.

[0095] Specifically, before atomization, that is, during the idle phase of the electronic atomizer, the control device compares the detected pressure value P3 within the liquid supply chamber with the detected ambient atmospheric pressure value P2. In response to a pressure difference D2 between the pre-atomization pressure value P3 of the liquid supply chamber and the ambient atmospheric pressure value P2 being within a non-preset range, the control device activates the liquid supply mechanism. The non-preset range may include a pressure difference D2 not equal to 0, or a pressure difference D2 greater than 10 Pa, 20 Pa, or 50 Pa.

[0096] Specifically, in one scenario, the pressure value P3 in the liquid supply chamber is less than the external atmospheric pressure value P2. At this time, the control device controls the liquid supply mechanism to drive the aerosol generating matrix in the liquid storage chamber to supply liquid to the liquid supply chamber, so that the pressure difference D2 between the pressure value P3 in the liquid supply chamber and the external atmospheric pressure value P2 is within a preset range.

[0097] In another scenario, the pressure value P3 in the liquid supply chamber is greater than the external atmospheric pressure value P2. At this time, the control device controls the liquid supply mechanism to drive the aerosol-generating matrix in the liquid supply chamber to guide the liquid to the liquid storage chamber, so that the pressure difference D2 between the pressure value P3 in the liquid supply chamber and the external atmospheric pressure value P2 is within a preset range.

[0098] Step S02: in response to the pressure difference between the pressure value of the liquid supply chamber before atomization and the preset pressure value being within a preset range, controlling the liquid supply mechanism to shut down.

[0099] Specifically, when the liquid supply mechanism operates so that the pressure value P3 in the liquid supply chamber and the external atmospheric pressure value P2 are within a preset range, the pressure difference D2 between the pressure value P3 in the liquid supply chamber before atomization and the external atmospheric pressure value P2 is substantially balanced. In response to the pressure difference D2 between the pressure value P3 in the liquid supply chamber before atomization and the external atmospheric pressure value P2 being within the preset range, the control device controls the liquid supply mechanism to shut down. At this time, the pressure value P3 in the liquid supply chamber is substantially the same as the actual external atmospheric pressure value P2. The preset range may be that the pressure difference D2 is equal to 0, or that the pressure difference D2 is within the range of 0-10Pa, 0-20Pa, or 0-50Pa.

[0100] It should be noted that the step of balancing the pressure value P3 within the liquid supply chamber with the external atmospheric pressure value P2 occurs during the idle phase of the electronic atomizer device. After the electronic atomizer device responds to the puff trigger signal, the control device controls the operation of the liquid supply mechanism based solely on the difference D1 between the current pressure value P1 and the preset pressure value P0. Specifically, the control device can determine that the electronic atomizer device is in the idle phase based on a preset time period after the atomizer component has been inactive, for example, 10 minutes, 20 minutes, or longer, to avoid affecting the user's normal puffing.

[0101] See also Figure 12 , Figure 12 Yes Figure 10 , a flow chart of an embodiment of step S2 is shown in FIG. In this embodiment, step S2 includes:

[0102] Step S21: In response to the difference reaching a preset first limit, the liquid supply mechanism is controlled to start, so as to drive the liquid in the liquid storage chamber to supply the liquid to the liquid supply chamber.

[0103] Specifically, in response to a puff trigger signal, the atomizer assembly atomizes the aerosol-generating substrate. As the aerosol-generating substrate within the micropores of the atomizer assembly is consumed, capillary forces are generated within the micropores, directing the aerosol-generating substrate within the liquid supply chamber to the atomizer assembly, thereby causing the pressure within the liquid supply chamber to change. As the aerosol-generating substrate within the liquid supply chamber is atomized and consumed by the atomizer assembly, the control device calculates the difference D1 between the current pressure value P1 and the preset pressure value P0. In response to the difference D1 detected by the first sensing element reaching a preset first limit X1, the control device activates the liquid supply mechanism, driving the aerosol-generating substrate within the liquid storage chamber to supply liquid to the liquid supply chamber.

[0104] The first limit value X1 can be determined experimentally. When the difference D1 between the current pressure value P1 and the preset pressure value P0 falls within the first limit value X1, the aerosol-generating substrate in the liquid supply chamber can be uniformly supplied to the atomizer assembly. Of course, the first limit value X1 can also be set to 0, that is, as soon as the aerosol-generating substrate in the liquid supply chamber is consumed, the liquid storage chamber begins supplying liquid to the liquid supply chamber, thereby maintaining the current pressure value in the liquid supply chamber in equilibrium with the preset pressure value.

[0105] In one embodiment, the first limit value X1 has a value range of -100 Pa to -200 Pa, that is, the current pressure value P1 is less than the preset pressure value P0, and the difference D1 between the current pressure value P1 and the preset pressure value P0 is 100 Pa to 200 Pa. For example, when the current pressure value P1 is less than the preset pressure value P0, and the difference D1 between the current pressure value P1 and the preset pressure value P0 reaches 150 Pa, the control device controls the liquid supply mechanism to activate, thereby driving the aerosol-generating substrate in the liquid storage chamber to supply liquid to the liquid supply chamber.

[0106] Step S22: In response to the difference reaching a preset second limit, the liquid supply mechanism is controlled to shut down, so as to stop driving the liquid in the liquid storage chamber to supply the liquid to the liquid supply chamber.

[0107] Specifically, as the liquid supply mechanism drives the aerosol-generating matrix in the liquid storage chamber to supply liquid to the liquid supply chamber, the control device calculates the difference D1 between the current pressure value P1 and the preset pressure value P0. In response to the difference D1 between the current pressure value P1 and the preset pressure value P0 detected by the first sensing element reaching a preset second limit value X2, the control device controls the liquid supply mechanism to shut down to stop driving the aerosol-generating matrix in the liquid storage chamber to supply liquid to the liquid supply chamber.

[0108] Among them, the second limit value X2 is greater than the first limit value X1, and the second limit value X2 can be obtained through experiments. When the difference D1 between the current pressure value P1 and the preset pressure value P0 reaches within the second limit value X2, it can be ensured that the aerosol generating matrix in the liquid supply chamber is evenly supplied to the atomization component, and the aerosol generating matrix in the liquid supply chamber will not leak due to excessive pressure in the liquid supply chamber.

[0109] In one embodiment, the second limit value X2 is in the range of 250 Pa to 350 Pa, i.e., the current pressure value P1 is greater than the preset pressure value P0, and the difference D1 between the current pressure value P1 and the preset pressure value P0 is in the range of 250 Pa to 350 Pa. For example, when the current pressure value P1 is greater than the preset pressure value P0, and the difference D1 between the current pressure value P1 and the preset pressure value P0 reaches 300 Pa, the control device controls the liquid supply mechanism to shut down, thereby stopping driving the aerosol-generating substrate in the liquid storage chamber to supply liquid to the liquid supply chamber.

[0110] Of course, the second limit value X2 can also be set to 0, that is, as long as the current pressure value P1 in the liquid supply chamber is equal to the preset pressure value P0, the liquid storage chamber stops supplying liquid to the liquid supply chamber to keep the current pressure value in the liquid supply chamber always balanced with the preset pressure value.

[0111] It should be noted that the time it takes for a user to take a puff of the electronic atomization device generally lasts about 3-5 seconds, and a single liquid supply may or may not maintain the amount of aerosol-generating matrix required for atomization when the user takes a puff. Therefore, in a single puff trigger signal, the control device may control the liquid supply mechanism to drive the aerosol-generating matrix in the liquid storage chamber to supply liquid to the liquid supply chamber N times (N=0, 1, 2, ...), that is, the difference D1 reaches the first limit X1 N times. Correspondingly, the control device may control the liquid supply mechanism to stop driving the aerosol-generating matrix in the liquid storage chamber to supply liquid to the liquid supply chamber M times, that is, the difference D1 reaches the second limit X2 M times (M=0, 1, 2, ...), thereby ensuring that the sol-generating matrix content in the liquid supply chamber can maintain the user's puff. Figure 13 As shown, Figure 13This is a curve diagram of an embodiment of the difference between the current pressure value and the preset pressure value in the liquid supply chamber during liquid supply provided by the present application, wherein the horizontal axis represents time and the vertical axis represents the difference D1 between the current pressure value P1 and the preset pressure value P0 in the liquid supply chamber. Figure 13 As shown, a plurality of upper and lower peaks may appear in a single puff trigger signal T. That is, in a single puff trigger signal T, the aerosol-generating matrix in the liquid storage chamber may be consumed immediately after the aerosol-generating matrix in the liquid supply chamber is supplied to the liquid supply chamber. As a result, the liquid storage chamber needs to supply liquid to the liquid supply chamber multiple times so that the current pressure value P1 in the liquid supply chamber is always higher than the lower pressure limit.

[0112] In another embodiment, step S2 includes: in response to the difference D1 reaching a preset first limit X1, controlling the liquid supply mechanism to start, and keeping the liquid supply mechanism running for a preset time.

[0113] Specifically, the control device calculates a difference D1 between a current pressure value P1 and a preset pressure value P0. In response to the difference D1 detected by the first sensing element reaching a preset first limit X1, the control device controls the liquid supply mechanism to start and operate for a preset duration, thereby driving the aerosol-generating substrate in the liquid storage chamber to supply liquid to the liquid supply chamber within the preset duration. After the liquid supply mechanism has operated for the preset duration, the control device controls the liquid supply mechanism to shut down, thereby ceasing the driving of the aerosol-generating substrate in the liquid storage chamber to supply liquid to the liquid supply chamber.

[0114] Among them, the preset time length can be obtained through experiments. When the difference D1 between the current pressure value P1 and the preset pressure value P0 in the liquid supply chamber reaches the first limit value X1, the control device controls the liquid supply mechanism to run for the preset time length, so that the current pressure value P1 in the liquid supply chamber is greater than or equal to the preset pressure value P0, and the difference D1 between the current pressure value P1 and the preset pressure value P0 in the liquid supply chamber is in the range of 0 to the second limit value X2. For example, the first limit value X1 is -100Pa, the second limit value X2 is 300Pa, and the current pressure value P1 in the liquid supply chamber obtained by the control device based on the detection of the first sensing element is less than the preset pressure value P0, and the difference D1 between the current pressure value P1 and the preset pressure value P0 is 100Pa, the control device controls the liquid supply mechanism to run for a preset time. After the liquid supply mechanism runs for the preset time, the control device controls the liquid supply mechanism to shut down. At this time, the current pressure value P1 in the liquid supply chamber is greater than or equal to the preset pressure value P0, such as, the difference D1 between the current pressure value P1 and the preset pressure value P0 is within the range of 0Pa-300Pa, but not exceeding 300Pa.

[0115] The control device 30 may be a control circuit board or a computer device, see Figure 14 , Figure 14FIG3 is a block diagram of an embodiment of a computer device provided by the present application. The computer device includes a processor 301 and a memory 302 connected to each other.

[0116] The memory 302 stores computer programs.

[0117] The processor 301 is configured to execute computer programs stored in the memory 302 .

[0118] The processor 301 may also be referred to as a CPU (Central Processing Unit). The processor 301 may be an integrated circuit chip having signal processing capabilities.
