[0042] See Figure 1-Figure 5 In one embodiment of the present application, an electronic atomization device 100 is provided, including a shell module 10, a battery module 40 and an atomization module 60. The battery module 40 and the atomization module 60 can be detachably installed in the shell module 10. When the electronic atomization device 100 is inhaled, the battery module 40 and the atomization module 60 are electrically connected through the shell module 10, so that the battery module 40 supplies power to the atomization module 60. In this way, after the atomization module 60 is energized, it heats the atomized aerosol to generate a matrix, forming an aerosol for the user to inhale and consume.

[0043] The housing module 10 includes a shell 12, a first contact terminal assembly 14, and a second contact terminal assembly 15. The shell 12 has a first accommodating cavity 122 and a second accommodating cavity 124. The first contact terminal assembly 14 and the second contact terminal assembly 15 are respectively arranged on the shell 12 corresponding to the first accommodating cavity 122 and the second accommodating cavity 124. The atomizer module 60 is detachably arranged in the atomizer module 60 mounting cavity, and the first contact terminal assembly 14 can contact and electrically connect with the atomizer module 60. The battery cell module 40 is detachably arranged in the battery cell module 40 mounting cavity, and the second contact terminal can contact and electrically connect with the battery cell module 40. The first contact terminal assembly 14 and the second contact terminal assembly 15 are controlled to be connected and disconnected with each other, and the battery cell module 40 and the atomizer module 60 can be electrically connected through the connection between the first contact terminal assembly 14 and the second contact terminal assembly 15.

[0044] In this way, the electronic atomization device 100 is modularly arranged. During the installation process of the electronic atomization device 100, it is only necessary to install the atomization module 60 and the battery cell module 40 on the shell module 10, and the electrical connection between the atomization module 60 and the battery cell module 40 can be achieved through the shell module 10. There is no complicated electrical connection in the installation process, the assembly process is simple and convenient, and the assembly efficiency is high.

[0045] In some embodiments, the shell 12 of the housing module 10 further has an air inlet cavity 13, which connects the outside with the first accommodating cavity 122. The first contact terminal assembly 14 and the second contact terminal assembly 15 are controlled to be connected to each other when there is suction airflow flowing in the air inlet cavity 13. The first contact terminal assembly 14 and the second contact terminal assembly 15 are controlled to be disconnected from each other when there is no suction airflow flowing in the air inlet cavity 13. The air inlet cavity 13 is set in the shell 12. When the user draws on the electronic atomization device 100, the external airflow can enter the air inlet cavity 13 and then flow to the atomization module 60. When there is suction airflow in the air inlet cavity 13, it indicates that the user has started to draw. The first contact terminal assembly 14 and the second contact terminal assembly 15 are controlled to be connected to each other to connect the battery module 40 and the atomization module 60, and to supply power to the atomization module 60.

[0046] Furthermore, the shell module 10 also includes an airflow sensor 16, and the first contact terminal assembly 14 and the second contact terminal assembly 15 are both connected to the airflow sensor 16. The airflow sensor 16 is arranged in the air inlet cavity 13, and the first contact terminal assembly 14 and the second contact terminal assembly 15 are connected when the suction airflow is sensed. In this way, the airflow sensor 16 is used to sense the suction airflow, and the first contact terminal assembly 14 and the second contact terminal assembly 15 are both connected to the airflow sensor 16. The first contact terminal assembly 14 and the second contact terminal assembly 15 can be connected through the airflow sensor 16 when there is suction airflow, and the airflow sensor 16 can also not be connected to the first contact terminal assembly 14 and the second contact terminal when there is no suction airflow.

[0047] Optionally, the airflow sensor 16 is a microphone, which is integrated with a control circuit. When the microphone senses the suction airflow, the control circuit connects the first contact terminal assembly 14 and the second contact terminal assembly 15 to form a closed power supply circuit. When the microphone does not sense the suction airflow, the control circuit does not connect the first contact terminal assembly 14 and the second contact terminal assembly 15. In this way, the battery cell module 40 and the atomization module 60 are connected only during suction for heating and atomization, and the battery cell module 40 and the atomization module 60 are disconnected at other times, which can prevent the atomization module 60 from starting accidentally.

[0048] In some embodiments, the first contact terminal assembly 14 includes a first positive elastic pin 141 and a first negative elastic pin 143, and the second contact terminal assembly 15 includes a second positive elastic pin 151 and a second negative elastic pin 153. The first positive elastic pin 141 and the first negative elastic pin 143 are connected to the microphone through a wire, and the second positive elastic pin 151 and the second negative elastic pin 153 are also connected to the microphone through a wire, and the first positive elastic pin 141 and the second positive elastic pin 151 can be connected, and the first negative elastic pin 143 and the second negative elastic pin 153 can be connected through the control circuit inside the microphone, thereby realizing the connection between the first contact terminal assembly 14 and the second contact terminal assembly 15.

[0049] In some embodiments, the housing 12 includes a first shell 121, a base 123 and a partition 125. The base 123 is mounted on one end of the first shell 121, and the partition 125 is arranged in the first shell 121. The base 123 and the partition 125 are spaced apart from each other and the two are enclosed to form an air inlet cavity 13. A first accommodating cavity 122 and a second accommodating cavity 124 are formed in sequence along the first direction in the space between the partition 125 and the first shell 121; wherein the first direction is parallel to the partition 125, the first contact terminal assembly 14 is arranged on the partition 125 corresponding to the first accommodating cavity 122, and the second contact terminal is arranged on the partition 125 corresponding to the second accommodating cavity 124.

[0050] In this way, different cavities are formed within the housing 12 to accommodate the atomizer module 60, the battery module 40, and for air intake. At the same time, the first contact terminal assembly 14 can be arranged on the partition 125, so that the first contact terminal assembly 14 is located at the bottom of the first accommodating cavity 122. When the atomizer module 60 is installed in the housing 12, it can contact the first contact terminal assembly 14 at the bottom to achieve electrical connection; and the second contact terminal assembly 15 can be arranged on the partition 125, so that the second contact terminal assembly 15 is located at the bottom of the second accommodating cavity 124. When the battery module 40 is installed in the housing 12, it can contact the second contact terminal assembly 15 at the bottom to achieve electrical connection.

[0051] Furthermore, a first stopper 32 is provided inside the first housing 121. The first stopper 32 and a portion of the side wall of the first housing 121 define a first accommodating cavity 122. The first stopper 32 cooperates with the first housing 121 to restrict the atomization module 60 within the first housing 121. Optionally, the first stopper 32 is an arc-shaped protrusion provided on the inner wall of the first housing 121.

[0052] Furthermore, a second stopper 34 is provided inside the first housing 121. The second stopper 34 and another portion of the sidewall of the first housing 121 define a second accommodating cavity 124. The second stopper 34 cooperates with the first housing 121 to retain the battery cell module 40 within the first housing 121. Optionally, the second stopper is an arc-shaped protrusion provided on the inner wall of the first housing 121.

[0053] See Figure 5-Figure 7In some embodiments, the cell module 40 includes a cell 42 and a cell housing 44. A first electrode 46 and a second electrode 48 are disposed on the outer surface of the cell housing 44. The cell 42 is disposed within the cell housing 44 and is in communication with the first and second electrodes 46, 48. Thus, the cell module 40 is configured such that the first and second electrodes 46, 48 are formed on the outer surface of the bottom of the cell housing 44, and the cell 42 is in communication with the first and second electrodes 46, 48. When the cell module 40 is installed into the second accommodating cavity 124, the first and second electrodes 46, 48 at the bottom of the cell module 40 can contact the second contact terminal assembly 15 at the bottom of the second accommodating cavity 124, thereby connecting the cell 42 with the second contact terminal assembly 15, allowing the second contact terminal assembly 15 to output electrical energy from the cell 42. Thus, once the cell module 40 is installed, the cell module 40 and the second contact terminal assembly 15 are electrically connected, without requiring additional electrical connection processes. The installation and electrical connection process is simple and convenient.

[0054] In addition, the positive and negative electrodes of the battery cell 42 itself have low flatness due to limitations of the manufacturing process. In order to ensure good contact and conductivity between the battery cell 42 and the second contact terminal, a first electrode 46 and a second electrode 48 are set at the bottom of the battery cell shell 44 to form a flat contact surface for effective conduction.

[0055] In some embodiments, the first electrode 46 and the second electrode 48 are concentrically arranged, and at least one of the first electrode 46 and the second electrode 48 is a ring-shaped electrode that can contact the first contact terminal at any angle. This allows the battery cell module 40 to be inserted into the second accommodating cavity 124 without requiring a specific insertion angle. Inserting the battery cell module 40 at any angle will allow the first electrode 46 and the second electrode 48 to contact the first contact terminal assembly 14 , facilitating user installation of the battery cell module 40.

[0056] Specifically, in one embodiment, one of the first electrode 46 and the second electrode 48 is a block electrode, and the other of the first electrode 46 and the second electrode 48 is a ring electrode. The ring electrode is arranged in a circular shape with the block electrode as the center. In this way, when the battery cell module 40 is installed in the second accommodating cavity 124, it does not need to be inserted at a specific angle. The battery cell module 40 can be inserted at any angle to enable the block electrode and the ring electrode to contact the first contact terminal assembly 14, which facilitates the user to install the battery cell module 40. It is understandable that in other embodiments, the first electrode 46 and the second electrode 48 are ring electrodes that are nested with each other, and the two are concentrically nested, which allows the battery cell module 40 to remain electrically connected after being rotated at any angle.

[0057] In some embodiments, the cell housing 44 includes a first half housing 441, a second half housing 443, and a first circuit board 445. The first half housing 441 and the second half housing 443 engage with each other and surround the periphery of the cell 42 on different sides. The first circuit board 445 is fixed to the opening formed by the first half housing 441 and the second half housing 443. The first electrode 46 and the second electrode 48 are formed on the outside of the first circuit board 445. Thus, when the first half housing 441 and the second half housing 443 engage, a space is formed to accommodate the cell 42. At the same time, the first circuit board 445 can be clamped and fixed by the first half housing 441 and the second half housing 443, so that the first electrode 46 and the second electrode 48 on the first circuit board 445 can achieve good contact and conduction with the second contact terminal assembly 15 in the housing module 10.

[0058] See Figure 2-Figure 4 In some embodiments, the electronic atomization device 100 further includes a nozzle 90, which is sleeved on the housing 12 and covers the opening of the second accommodating chamber 124 and the opening of the first accommodating chamber 122. The nozzle 90 has an air outlet channel 92 inside that connects the atomization module 60 with the outside world. During the installation process, the battery module 40 and the atomization module 60 are installed in the housing module 10, and finally the nozzle 90 is installed on the housing 12. The nozzle 90 can shield the battery module 40 and the atomization module 60 to prevent the battery module 40 and the atomization module 60 from being removed from the housing 12. At the same time, the user can inhale the electronic atomization device 100 through the nozzle 90, and the aerosol generated by the atomization module 60 is sucked to the outside through the air outlet channel 92 for the user to consume.

[0059] See Figure 4 and Figure 8-Figure 9 In some embodiments, the atomization module 60 includes an atomization housing 62, an atomization assembly 64 disposed in the atomization housing 62, and a third electrode 66 and a fourth electrode 68 disposed on the outer surface of the bottom of the atomization housing 62. The third electrode 66 and the fourth electrode 68 are both electrically connected to the atomization assembly 64. In this way, the third electrode 66 and the fourth electrode 68 are made on the outer surface of the bottom of the atomization housing 62. When the atomization module 60 is installed in the first accommodating cavity 122 of the housing 12, the third electrode 66 and the fourth electrode 68 can contact the first contact terminal assembly 14 located at the bottom of the first accommodating cavity 122, thereby conducting electricity between the atomization module 60 and the first contact terminal assembly 14. In this way, the electrical connection can be achieved by simply installing the atomization module 60 in place, without the need for additional electrical connection processes, and the installation process is simple and convenient.

[0060] Furthermore, the atomizing housing 62 includes a second housing 621, a first sealing member 623, and a second circuit board 625. The first sealing member 623 is provided at an opening at one end of the second housing 621. The atomizing assembly 64 is provided on the first sealing member 623 and is located inside the second housing 621. The second circuit board 625 is fixed to a side of the first sealing member 623 away from the interior of the second housing 621. A third electrode 66 and a fourth electrode 68 are formed on the outer surface of the second circuit board 625. The atomizing assembly 64 is electrically connected to the third electrode 66 and the fourth electrode 68. In this way, the connecting pins of the atomizing assembly 64 are electrically connected to the third electrode 66 and the fourth electrode 68, thereby achieving electrical connection between the second circuit board 625 and the atomizing assembly 64. At the same time, the first sealing member 623 seals the opening at the end of the second housing 621 and fixes the second circuit board 625, thereby allowing the second circuit board 625 to contact the first contact terminal assembly 14.

[0061] Specifically, a first air inlet hole 72 is defined on the second circuit board 625, and a second air inlet hole 74 is defined on the first sealing member 623, connecting the first air inlet hole 72 with the atomizer assembly 64. The first air inlet hole 72 is in communication with the air inlet cavity 13. When the external air flows from the air inlet cavity 13 to the first accommodating cavity 122, it passes through the first air inlet hole 72 and the second air inlet hole 74 in sequence, and finally enters the atomizer assembly 64 to carry the aerosol generated by atomization.

[0062] In addition, the first sealing member 623 is provided to protrude along the axial direction of the second shell 621 toward the side away from the second shell 621, that is, the first sealing member 623 protrudes from the bottom of the second shell 621. When the atomizer module 60 is installed in the atomizer module 60 installation cavity of the shell 12, the protruding portion of the first sealing member 623 can be inserted into the sealing groove 128 at the bottom of the atomizer module 60 installation cavity. In this way, the protruding portion of the first sealing member 623 cooperates with the sealing groove 128 to seal the joint between the atomizer module 60 and the shell 12, thereby guiding the airflow from the air inlet cavity 13 of the shell 12 to the airflow channel of the atomizer module 60, preventing the airflow from leaking from the gap between the atomizer module 60 and the shell 12, and ensuring the airtightness of the airflow.

[0063] Specifically, a limiting protrusion ring 126 is protruded from the surface of the partition 125 in the outer shell facing the installation cavity of the atomization module 60, and a sealing groove 128 is formed inside the limiting protrusion ring 126. During the installation process, the first sealing member 623 protruding from the bottom of the atomization module 60 can penetrate into the sealing groove 128 of the limiting protrusion ring 126 to achieve a sealed installation of the two and improve the airtightness during the airflow process.

[0064] In some embodiments, two oppositely arranged pin welding points 63 are formed on the outer surface of the second circuit board 625, the third electrode 66 and the fourth electrode 68 are arranged relatively spaced apart along the second direction, the two pin welding points 63 are arranged relatively spaced apart along a third direction intersecting the second direction, and two groups of mutually spaced threading holes 626 are arranged between the third electrode 66 and the fourth electrode 68, and each group of threading holes 626 includes two threading holes 626 spaced apart along the third direction.

[0065] The welding pins of the atomizer component 64 need to pass through the threading holes 626 and be welded to the pin welding points 63 on the outer surface of the second circuit board 625. Moreover, the welding pins of the atomizer component 64 are generally deviated from the center position and are located on the side close to the third electrode 66 in the second direction, or on the side close to the fourth electrode 68 in the second direction. If there is only one set of threading holes 626, when the second circuit board 625 is rotated 180 degrees, it is possible that the set of threading holes 626 close to the fourth electrode 68 is rotated to be close to the third electrode 66, while the pins of the atomizer component 64 are still located on the side of the fourth electrode 68. At this time, the pins cannot be passed through the threading holes 626. Therefore, the second circuit board 625 must be assembled at a fixed angle to weld the pins, which affects the assembly efficiency. Therefore, in some embodiments, two groups of threading holes 626 corresponding to the third electrode 66 and the fourth electrode 68 are provided. When the second circuit board 625 is rotated 180 degrees, the pins of the atomizer assembly 64 still have corresponding threading holes 626. The installation process has lower requirements on the installation angle of the second circuit board 625, which facilitates the installation of the second circuit board 625.

[0066] See Figures 8-11 In some embodiments, a top plate 76 is provided on the side of the second housing 621 away from the second circuit board 625. A back-suction groove 77 is provided on the top plate 76, connecting the air outlet channel 92 with the interior of the second housing 621. Thus, when a user draws from the electronic atomization device 100, if condensation forms in the air outlet channel 92 of the nozzle 90, the condensation can flow into the interior of the second housing 621 through the back-suction groove 77 on the top plate 76, preventing the condensation from leaking out along the air outlet channel 92 of the nozzle 90 and improving the user experience.

[0067] Furthermore, the atomization module 60 also includes liquid-absorbing cotton 82 and oil-storage cotton 84. The liquid-absorbing cotton 82 is disposed on the top plate 76 and is in fluid communication with the air outlet channel 92. The oil-storage cotton 84 is disposed within the second housing 621 and is in fluid communication with the back-suction groove 77. The interior of the second housing 621 functions as a liquid storage chamber, capable of storing liquid for the aerosol-generating matrix within the second housing 621 to supply the liquid to the atomization assembly 64.

[0068] Moreover, an oil storage cotton 84 is provided inside the second shell 621, and the aerosol generating matrix can be adsorbed and stored in the oil storage cotton 84. When the user is inhaling and using the electronic atomization device 100, the aerosol generating matrix in the oil storage cotton 84 gradually moves from top to bottom, and the aerosol generating matrix stored in the upper part of the oil storage cotton 84 near the suction nozzle 90 gradually decreases, and the oil storage cotton 84 gradually becomes dry. At the same time, the condensate formed in the air outlet channel 92 of the suction nozzle 90 can flow back to the liquid absorbent cotton 82 above the top plate 76, and be absorbed and stored by the liquid absorbent cotton 82 to prevent the condensate from leaking. Afterwards, when the condensate absorbed by the liquid absorbent cotton 82 accumulates to a certain extent, it will be sucked back by the back-suction groove 77 on the lower top plate 76 through the capillary suction phenomenon, and will be sucked back and stored by the relatively dry liquid storage surface along the back-suction groove 77 to prevent leakage during the suction process.

[0069] In this way, the condensate is absorbed and stored by the end of the oil storage cotton 84 close to the suction nozzle 90, and the condensate can be smoothly sucked back and stored. If there is no oil storage cotton 84, the condensate may continue to hang on the inner wall of the second shell 621, and there is still a risk of leakage. The dry end of the oil storage cotton 84 can well preserve the condensate, and the condensate will not leak easily, and the leakage discharge effect is better.

[0070] Specifically, in some embodiments, the back-absorption groove 77 includes a first groove 771, a second groove 773, and a connecting groove 775. The first groove 771 and the second groove 773 are respectively provided on the front and back sides of the top plate 76, and the connecting groove 775 connects the first groove 771 and the second groove 773. Thus, the first groove 771 is located on the front side of the top plate 76, facing the liquid-absorbing cotton 82 above the top plate 76, and the second groove 773 is located on the back side of the top plate 76, facing the oil-storing cotton 84 below the top plate 76. Condensate in the liquid-absorbing cotton 82 can be back-absorbed by the first groove 771, then flow along the connecting groove 775 to the second groove 773, and finally absorbed by the oil-storing cotton 84 from the second groove 773.

[0071] In some embodiments, the atomization module 60 further includes a second sealing member 86. A side of the top plate 76 away from the second circuit board 625 and the second shell 621 enclose a receiving cavity, and the second sealing member 86 is disposed in the receiving cavity. The suction nozzle 90 includes an outer wall 93 and an air outlet pipe 91 disposed in the outer wall 93 and having an air outlet channel 92. A through hole is provided on the second sealing member 86, and the air outlet pipe 91 is sleeved in the through hole. The outer wall 93 is buckled with the shell 12. In this way, the second sealing member 86 is provided above the top plate 76. When the outer wall 93 of the suction nozzle 90 is buckled with the shell 12 of the housing module 10, the air outlet pipe 91 is sleeved into the through hole of the second sealing member 86. The second sealing member 86 seals the joint between the suction nozzle 90 and the atomization module 60 to prevent air leakage.

[0072] Furthermore, the absorbent cotton 82 is sleeved in the second sealing member 86. When the second sealing member 86 is arranged in the accommodating cavity, the absorbent cotton faces the top plate 76. The absorbent cotton 82 can absorb the condensed liquid falling from the inner wall of the air outlet channel 92 and guide it into the back-suction groove 77 of the top plate 76.
