[0030] See also Figure 2 and Figure 3 , and combined with Figure 5The atomizer bomb 100 of the present application includes a shell assembly 10, a heating assembly 30 and an electrode assembly 50. The shell assembly 10 is provided with a liquid storage chamber 101 and an installation chamber 102, and the liquid storage chamber 101 is used to accommodate an aerosol generating matrix. The heating assembly 30 is arranged in the installation chamber 102, and the heating assembly 30 includes a heating element 31 in contact with the aerosol generating matrix, and a heating circuit 301 is provided on the heating element 31. The electrode assembly 50 is arranged in the installation chamber 102, and the electrode assembly 50 includes a first electrode 51, a second electrode 53 and a third electrode 55, and the first electrode 51 and the second electrode 53 are respectively connected to the heating element 31, and the first electrode 513 is electrically connected to the second electrode 53 via the heating circuit 301. The heating circuit 301 is used to heat the heating element 31. The third electrode 55 and any one of the first electrode 51 and the second electrode 53 are used to form a detection circuit 701, and the detection circuit 701 includes a detector 73, and the detector 73 is used to detect the resistance change between the third electrode 55 and the first electrode 51; or the detector 73 is used to detect the resistance change between the third electrode 55 and the second electrode 53.

In the case where there is still an aerosol generating matrix in the liquid storage chamber 101, the resistance value measured by the detection circuit 701 will be less than the resistance value measured by the detection circuit 701 when there is no aerosol generating matrix in the liquid storage chamber 101. The detection circuit 701 can detect the change in resistance through the change in electrical parameters between the third electrode 55 and any one of the first electrode 51 and the second electrode 53, and judge the amount of liquid in the liquid storage chamber 101 at this time to avoid waste of liquid.

[0033] The atomizing bomb 100 is further described below with reference to the accompanying drawings.

[0034] See also Figure 2 and Figure 3 , and combined with Figure 1In some embodiments, the shell component 10 is a structure for accommodating the aerosol generating matrix and other structures in the atomizing bomb 100, and can discharge the generated aerosol. Among them, the aerosol is a multiphase fluid with a gaseous state as a continuous phase and a solid and a liquid state as a dispersed phase. In some embodiments, the aerosol generating matrix can be a mixed solution carrier carrying the aerosol generating matrix. The solute in the mixed solution can include nicotine, nicotine salts and plant extracts, etc., and the solvent in the mixed solution can be common organic solutes and / or inorganic solutes such as propylene glycol, vegetable glycerin and pure water. The heating component 30 in the atomizing bomb 100 can perform operations such as heating the mixed solution to disperse the mixed solution into tiny droplets and form an aerosol after mixing with air. The material of the shell component 10 includes but is not limited to high temperature resistant materials such as metal, plastic or acrylonitrile-butadiene-styrene copolymer (ABS resin). The liquid storage chamber 101 and the mounting chamber 102 are both arranged in the housing assembly 10, and the liquid storage chamber 101 and the mounting chamber 102 are isolated from each other. When the user uses the atomizer bomb 100, the aerosol-generating matrix in the liquid storage chamber 101 will not flow into the mounting chamber 102 to affect the normal use of other structures of the atomizer bomb 100. Among them, the liquid storage chamber 101 and the mounting chamber 102 can be separated from each other by the partial structure of the housing assembly 10 as a boundary, can be separated from each other by the partial structure of the heating assembly 30 as a boundary, and can also be separated from each other by the boundary jointly formed by the partial structure of the housing assembly 10 and the partial structure of the heating assembly 30, which is not limited here. In some embodiments, the liquid storage chamber 101 can be connected to the outside to allow external gas to enter the liquid storage chamber 101, so as to maintain the air pressure balance in the liquid storage chamber 101 and avoid deformation or damage to the housing assembly 10. In other embodiments, the liquid storage chamber 101 can be isolated from the outside to prevent the aerosol-generating matrix in the liquid storage chamber 101 from leaking out.

[0035] Specifically, in some embodiments, the housing assembly 10 includes a housing 11 and a base 13. The housing 11 is generally a structure provided with an inner cavity, and the base 13 is generally a structure capable of being connected with the housing 11. In some embodiments, the housing 11 and the base 13 are integrally formed, and during the molding process of the housing 11 and the base 13, the other structures of the atomizer 100 and the aerosol generating matrix are installed in the mounting cavity 102 or poured into the liquid storage cavity 101. In other embodiments, the housing 11 and the base 13 are separately formed, and the housing 11 and the base 13 can be fixed together by a non-detachable connection method such as gluing, hot-melt connection or welding, or can be installed together by a detachable connection method such as threaded connection, snap-fit ​​connection or bolt connection, which is not limited here.

[0036] More specifically, the housing 11 includes a first end 111 and a second end 113 facing each other. The first end 111 of the housing 11 is provided with an opening 112, and the base 13 is provided at the first end 111 of the housing 11 and blocks the opening 112, so that the inner cavity of the housing 11 is isolated from the outside. When the user uses the atomizer cartridge 100, the second end 113 of the housing 11 can face the user, and the aerosol generated in the atomizer cartridge 100 can be discharged from the second end 113 of the housing 11 for the user to inhale.

[0037] More specifically, in some embodiments, the housing 11 includes a first portion 115 and a second portion 117 connected to each other, and the first portion 115 of the housing 11 is closer to the second end 113 of the housing 11 than the second portion 117 of the housing 11. The base 13 is disposed at the second portion 117 of the housing 11 and is located on a side of the second portion 117 of the housing 11 away from the first portion 115 of the housing 11. In some embodiments, the outer contour size of the cross section of the first portion 115 is smaller than the outer contour size of the cross section of the second portion 117, the liquid storage chamber 101 is disposed at the second portion 117 of the housing 11 to accommodate more aerosol generating substrates, and the first portion 115 of the housing 11 can form a nozzle for aerosol to pass through and can interact with the user. Among them, the first part 115 of the shell 11 is roughly a cylindrical structure with openings 112 at both ends. In some embodiments, along the direction of the second part 117 of the shell 11 pointing to the first part 115 of the shell 11, the outer contour size of the cross section of the first part 115 of the shell 11 gradually decreases, so that the size of the end of the first part 115 of the shell 11 facing the user adapts to the needs of the user, which is convenient for the user to inhale the aerosol. In other embodiments, along the direction of the second part 117 of the shell 11 pointing to the first part 115 of the shell 11, the outer contour size of the cross section of the first part 115 of the shell 11 is roughly the same. In some other embodiments, along the direction of the second part 117 of the shell 11 pointing to the first part 115 of the shell 11, the outer contour size of the cross section of the first part 115 of the shell 11 first decreases and then increases. At this time, the appearance of the nozzle conforms to the ergonomic design, which is more convenient to use and ensures that the aerosol will not overflow too much. In the direction from the second portion 117 of the shell 11 to the first portion 115 of the shell 11, in one example, the outer contour dimension of the cross section of one end of the first portion 115 of the shell 11 away from the second portion 117 of the shell 11 is always smaller than the outer contour dimension of the cross section of one end where the first portion 115 of the shell 11 is connected to the second portion 117 of the shell 11; in another example, the outer contour dimensions of the cross section at two opposite ends of the first portion 115 of the shell 11 are substantially the same.

[0038] Further, in some embodiments, the housing 11 is further provided with an exhaust channel 103, which is a cavity that penetrates the opposite ends of the housing 11 and communicates with the outside world along the direction from the second portion 117 of the housing 11 to the first portion 115 of the housing 11, and the cross-sectional shape of the exhaust channel 103 includes but is not limited to a circle, an ellipse, a triangle, a quadrilateral, a pentagon, a hexagon, etc. The aerosol generated in the atomizer bomb 100 can flow from the second portion 117 of the housing 11 to the first portion 115 of the housing 11 through the exhaust channel 103 and flow out from the side of the first portion 115 of the housing 11 away from the second portion 117 of the housing 11. When the user inhales the aerosol through the first portion 115 of the housing 11, the aerosol in the exhaust channel 103 can flow from one end of the exhaust channel 103 located at the first end 111 of the housing 11 to one end of the exhaust channel 103 located at the second end 113 of the housing 11, and be provided to the user for inhalation. The exhaust channel 103 is isolated from the liquid storage chamber 101 so that the un-atomized aerosol-generating matrix in the liquid storage chamber 101 will not enter the exhaust channel 103 and be inhaled by the user, thereby avoiding leakage of the aerosol-generating matrix and affecting the user's experience.

[0039] See also Figure 2 and Figure 3 In some embodiments, the heating component 30 is a structure capable of heating a liquid aerosol-generating substrate to atomize the aerosol-generating substrate to generate an aerosol. The heating element 31 in the heating component 30 can be in direct contact with the aerosol-generating substrate. When the heating element 31 is heated by the heating circuit 301 and generates heat, the aerosol-generating substrate that is in contact with the heating element 31 and partially wets the surface of the heating element 31 can be atomized to mix with air to form an aerosol, and is provided to the user for inhalation.

[0040] Specifically, the heating assembly 30 further includes a bracket 33, which is generally a structure arranged in the installation cavity 102 and capable of installing the heating element 31, with one side of the bracket 33 facing the installation cavity 102, and the other side of the bracket 33 facing the liquid storage cavity 101. The heating element 31 is arranged on the side of the bracket 33 facing the installation cavity 102 and can extend into the bracket 33 to contact the aerosol generating substrate in the liquid storage cavity 101. When the heating element 31 generates heat, the heating element 31 can heat the aerosol generating substrate to generate aerosol. The material of the bracket 33 includes but is not limited to high temperature resistant materials such as metal, plastic or acrylonitrile-butadiene-styrene copolymer (ABS resin), and the outer contour size of the cross section of the bracket 33 can be adapted to the inner contour size of the cross section of the second part 117 of the housing 11, so that the bracket 33 can be installed in the installation cavity 102. In some embodiments, the outer contour size of the cross section of the bracket 33 is smaller than the inner contour size of the cross section of the second part 117 of the housing 11. In other embodiments, the outer contour size of the cross section of the bracket 33 is equal to the inner contour size of the cross section of the second portion 117 of the housing 11. In still other embodiments, the outer contour size of the cross section of the bracket 33 is greater than the inner contour size of the cross section of the second portion 117 of the housing 11, and the two are interference fit.

[0041] Furthermore, in some embodiments, the housing assembly 10 further includes a seal 15, which is generally a flexible structure with relatively stable physical and chemical properties, and the material of the seal 15 includes but is not limited to rubber, silicone, plastic, etc. The seal 15 can be used to seal the gap between the housing 11 and the bracket 33 to prevent the aerosol-generating matrix from overflowing from the gap between the housing 11 and the bracket 33 and entering the installation cavity 102.

[0042] Specifically, the seal 15 is disposed in the shell 11 and divides the inner cavity of the shell 11 into a liquid storage cavity 101 and an installation cavity 102. In some embodiments, the seal 15 is sleeved on the bracket 33, and part of the structure of the seal 15 is located on the side of the bracket 33 facing the liquid storage cavity 101, and the other part of the structure of the seal 15 is located between the outer wall of the bracket 33 and the inner wall of the shell 11. At this time, the seal 15 and the second part 117 of the shell 11 together constitute the liquid storage cavity 101, and the seal 15, the second part 117 of the shell 11 and the base 13 together constitute the installation cavity 102. In other embodiments, the seal 15 is only disposed between the outer wall of the bracket 33 and the inner wall of the shell 11 to block the gap between the outer wall of the bracket 33 and the inner wall of the shell 11 to prevent the aerosol generating matrix from overflowing. At this time, the sealing member 15 , the bracket 33 and the second portion 117 of the housing 11 together form the liquid storage chamber 101 , and the sealing member 15 , the second portion 117 of the housing 11 and the base 13 together form the installation chamber 102 .

[0043] Furthermore, an atomizing chamber 104 is provided in the atomizing bomb 100, and the atomizing chamber 104 is a chamber that generates an aerosol and can be communicated with the exhaust channel 103. The heating element 31 is partially located in the atomizing chamber 104 so that the generated aerosol enters the atomizing chamber 104, and the aerosol in the atomizing chamber 104 can flow out of the housing assembly 10 through the exhaust channel 103. Specifically, the exhaust channel 103 can penetrate the first part 115 of the housing 11 and the second part 117 of the housing 11. In some embodiments, the atomizing chamber 104 is formed in the bracket 33. In other embodiments, the atomizing chamber 104 is formed in the base 13. In some other embodiments, the bracket 33 and the base 13 jointly form the atomizing chamber 104. The atomizing chamber 104 is isolated from the liquid storage chamber 101 to prevent the unatomized aerosol generating matrix in the liquid storage chamber 101 from entering the atomizing chamber 104 and being inhaled by the user together with the aerosol, causing leakage.

[0044] Further, in some embodiments, the base 13 is provided with an air inlet 131. In some embodiments, the air inlet 131 may be a structure for inputting gas into the atomizing chamber 104 so that the gas entering the atomizing chamber 104 can participate in forming an aerosol. When the user inhales the aerosol through the first portion 115 of the housing 11, the aerosol in the atomizing chamber 104 is drawn out through the exhaust passage 103, the air pressure in the atomizing chamber 104 and the exhaust passage 103 is reduced, and external gas can enter the atomizing chamber 104 through the air inlet 131 under the action of atmospheric pressure. In other embodiments, the air inlet 131 may also be a structure for inputting gas into the liquid storage chamber 101 to balance the air pressure in the liquid storage chamber 101. When the aerosol generating matrix in the liquid storage chamber 101 is reduced, the amount of gas in the liquid storage chamber 101 remains unchanged but the volume of the gas increases, so the air pressure in the liquid storage chamber 101 decreases, and external gas can enter the liquid storage chamber 101 and / or the atomization chamber 104 of the atomization bomb 100 through the air inlet 131 under the action of atmospheric pressure.

[0045] Furthermore, in some embodiments, the bracket 33 is provided with a liquid inlet hole 331 connected to the liquid storage chamber 101, and the heating element 31 blocks the liquid inlet hole 331 to prevent liquid leakage. The aerosol generating substrate can flow out of the liquid storage chamber 101 through the liquid inlet hole 331 and contact the heating element 31. When the aerosol generating substrate contacts the heating element 31 and the heating element 31 is in a heating state, the heating element 31 can heat the aerosol generating substrate and generate an aerosol.

[0046] Furthermore, in some embodiments, the heating component 30 also includes a sealing ring 35, which is generally a flexible structure with relatively stable physical and chemical properties, and the material of the sealing ring 35 includes but is not limited to rubber, silicone, plastic, etc. The sealing ring 35 is annular, and the sealing ring 35 is arranged on the side of the heating element 31 facing the bracket 33 and the liquid storage chamber 101 and is located between the heating element 31 and the bracket 33. The sealing ring 35 is arranged around the liquid inlet hole 331, that is, the position of the liquid inlet hole 331 is located within the inner contour of the sealing ring 35. The sealing ring 35 is used to seal the gap between the heating element 31 and the bracket 33 to prevent the aerosol-generating matrix that contacts the heating element 31 through the liquid inlet hole 331 from flowing into the atomization chamber 104 and / or the installation chamber 102 through the gap between the heating element 31 and the bracket 33. Cause leakage.

[0047] See also Figure 3 and Figure 4 In some embodiments, the electrode assembly 50 is generally a structure that can be electrically connected to the power supply of the atomizer bomb 100 and the heating element 31. In some embodiments, the power supply of the atomizer bomb 100 is disposed in the installation cavity 102 and is a battery that can store electricity. In other embodiments, the power supply of the atomizer bomb 100 is disposed outside the atomizer bomb 100. When the output connector of the power supply is electrically connected to the electrode assembly 50, the power supply can supply power to the heating element 31 in the atomizer bomb 100 to generate heat for the heating element 31.

[0048] Specifically, please combine Figure 5In some embodiments, the electrode assembly 50 is disposed on the base 13, and the electrode assembly 50 includes a first electrode 51, a second electrode 53 and a third electrode 55, the first electrode 51, the second electrode 53 and the third electrode 55 are electrically insulated from each other, and the third electrode 55 and the heating element 31 are electrically insulated from each other to avoid a short circuit of the power supply or the heating element 31 failing to work properly. In some embodiments, at least two of the first electrode 51, the second electrode 53 and the third electrode 55 are in physical contact with each other but are electrically insulated. In other embodiments, the first electrode 51, the second electrode 53 and the third electrode 55 are spaced apart from each other, and there is no physical contact between the three. When the circuit is connected, the loop between the first electrode 51 and the second electrode 53 is a heating circuit 301 for supplying power to the heating element 31, and the heating circuit 301 is a conductive metal powder layer coated on the surface of the heating element 31, one end of the first electrode 51 and one end of the second electrode 53 are electrically connected to the positive and negative electrodes of the power supply, respectively, and the other end of the first electrode 51 and the other end of the second electrode 53 are both electrically connected to the heating circuit 301 to supply power to the heating circuit 301. One end of the third electrode 55 is used to be electrically connected to a separate contact provided on the power supply, and the third electrode 55 and the first electrode 51 together constitute a part of the detection circuit 701 for detecting the resistance between the two, or the third electrode 55 and the second electrode 53 together constitute a part of the detection circuit 701 for detecting the resistance between the two.

[0049] Further, in some embodiments, please combine Figure 5 , the detection circuit 701 is a circuit structure that can obtain the resistance value and resistance value change in the detection circuit 701 by detecting the change of the potential difference between the third electrode 55 and the first electrode 51 or the third electrode 55 and the second electrode 53. Since the aerosol generating substrate can be partially conductive, when the aerosol generating substrate is in contact with the third electrode 55 and the first electrode 51 at the same time or the aerosol generating substrate is in contact with the third electrode 55 and the second electrode 53 at the same time, the aerosol generating substrate can be conductive, and the resistance value measured by the detection circuit 701 will be small at this time, and when the third electrode 55 and the first electrode 51 are completely out of contact with the aerosol generating substrate or the third electrode 55 and the second electrode 53 are completely out of contact with the aerosol generating substrate, it means that there is no aerosol generating substrate in the liquid storage chamber 101 at this time or the aerosol generating substrate infiltrated in the heating element 31 has been completely consumed, and the resistance value measured by the detection circuit 701 is large at this time. Therefore, by detecting the change in the resistance value measured by the detection circuit 701, it is possible to determine whether there is any aerosol generating matrix remaining in the atomizer cartridge 100 at this time.

[0050] Specifically, in some embodiments, the detection circuit 701 further includes a first resistor 71, which is connected in series with the heating circuit 301 and then grounded. The detection circuit 701 can detect the potential at the connection point between the heating circuit 301 and the first resistor 71. According to the potential at the connection point between the heating circuit 301 and the first resistor 71 Potential at the power supply The resistance value R1 of the first resistor 71 and the potential of the grounding point Get the resistance value R ref The specific formula is as follows:

[0051]

[0052] Since the first resistor 71 is a fixed resistor, the resistance value measured by the detection circuit 701 is the resistance value between the third electrode 55 and the first electrode 51 or the resistance value between the third electrode 55 and the second electrode 53. When the resistance value measured by the detection circuit 701 increases and the change value exceeds the first preset threshold value, it indicates that the third electrode 55 and the first electrode 51 are completely out of contact with the aerosol generating matrix or the third electrode 55 and the second electrode 53 are completely out of contact with the aerosol generating matrix, or the aerosol generating matrix infiltrated in the heating element 31 is consumed, the aerosol generating matrix in the atomizing bomb 100 is exhausted, and the heating circuit 301 stops supplying power to the heating circuit 301 to avoid dry burning of the atomizing bomb 100 and damage to the atomizing bomb 100. When the resistance value measured by the detection circuit 701 becomes smaller and the change value exceeds the second preset threshold value, it indicates that the aerosol generating matrix is ​​in contact with the third electrode 55 and the first electrode 51 at the same time or the aerosol generating matrix is ​​in contact with the third electrode 55 and the second electrode 53 at the same time, and the aerosol generating matrix in the atomizer bomb 100 is sufficient or there is a surplus, and the heating circuit 301 starts to supply power to the heating circuit 301 or continues to supply power to the heating circuit 301.

[0053] More specifically, in some embodiments, the detector 73 can be either a common analog to digital converter (ADC) that can be used to detect the potential at a certain point, or a microcontroller unit (MCU) integrated with an analog to digital converter. The detector 73 is arranged between the heating circuit 301 and the first resistor 71 and is electrically connected to the heating circuit 301 and the first resistor 71. The detector 73 is used to detect the potential at the connection point between the heating circuit 301 and the first resistor 71, so as to calculate and obtain the resistance value R according to the above formula. ref The change value of .

[0054] See also Figure 5 and Figure 6In some embodiments, since the DC stable power supply is generally formed by the AC power supply through rectification and voltage stabilization, the DC stable power supply will inevitably have some AC components in the DC stable quantity. This AC component superimposed on the DC stable quantity is the ripple in the detection circuit 701. The ripple will cause the potential measured by the detector 73 to fluctuate, and will be reflected in the calculation of the resistance value R ref Therefore, a filter circuit 703 needs to be provided in the atomizer cartridge 100 to filter the ripples in the detection circuit 701. The types of filter circuit 703 include, but are not limited to, passive filtering and active filtering. Passive filtering refers to a filtering method that uses passive filtering devices such as capacitors 75 and inductors to filter out harmonics of different frequencies. This application only shows the design method of the filter circuit 703 of passive filtering, which does not mean that only this type of circuit can be used in this application to filter the ripples in the detection circuit 701.

[0055] Specifically, in some embodiments, the filter circuit 703 includes a capacitor 75 and a second resistor 77. The second resistor 77 is connected in series with the capacitor 75, and the second resistor 77 and the capacitor 75 are connected in parallel with the first resistor 71. One end of the capacitor 75 is electrically connected to the connection point between the heating circuit 301 and the first resistor 71 via the second resistor 77, and the other end of the capacitor 75 is grounded. The second resistor 77 can adjust the cut-off frequency of the filter circuit 703, limit the current size or load the DC voltage output at the connection point between the heating circuit 301 and the first resistor 71. The capacitor 75 can filter out low-frequency signals in the current by repeated charging and discharging. In particular, in some embodiments, the filter circuit 703 is not provided in the atomizer bomb 100. In order to filter out the ripple in the rectifier output voltage and eliminate the calculated resistance R ref The error generated when the detector 73 is used can be used to reduce the error by measuring the potential at the connection point between the heating element 31 and the first resistor 71 multiple times and calculating the average value.

[0056] See also Figure 6 and Figure 7 The atomization device 1000 of the embodiment of the present application includes the atomization bomb 100 of any of the above-mentioned embodiments.

[0057] In the atomization device 1000 of the present application, the first electrode 51, the second electrode 53 and the third electrode 55 are all located outside the liquid storage chamber 101, and the heating element 31 can contact the aerosol generating matrix in the liquid storage chamber 101. When there is still an aerosol generating matrix in the liquid storage chamber 101, the resistance value measured by the detection circuit 701 will be less than the resistance value measured by the detection circuit 701 when there is no aerosol generating matrix in the liquid storage chamber 101. The detection circuit 701 can detect the change in resistance through the change in electrical parameters between the third electrode 55 and any one of the first electrode 51 and the second electrode 53, and judge the amount of liquid in the liquid storage chamber 101 at this time to avoid waste of liquid. The first electrode 51 and the second electrode 53 can also constitute a heating circuit 301 that can heat the heating element 31 to indirectly heat the aerosol generating matrix, and the circuit structure in the atomization bomb 100 is simpler.
