The pressure cylinder 314 is located in the receiving cavity 315. One end of the pressure cylinder 314 is a fixed end and is fixed on the top plate 311. The other end of the pressing cylinder 314 is a free end, so that the free end of the pressing cylinder 314 protrudes a certain height relative to the top plate 311 along the axial direction of the side cylinder 312 . In the case where the fixed bracket 310 exists alone, the top plate 311 and the pressing cylinder 314 together form a circumferentially closed storage cavity 3141. Obviously, the storage cavity 3141 is an open cavity with an opening at one end, so that the storage cavity 3141 communicates. The receiving cavity 315 .

The fixed bracket 310 also includes a limiting block 316, which protrudes from the inner side of the side tube 312 and is accommodated in the receiving cavity 315, so that the limiting block 316 protrudes along the radially opposite side tube 312 of the side tube 312 The inner side protrudes a certain length. The limiting block 316 can have a certain length along the axial direction of the side cylinder 312 , for example, one end of the side cylinder 312 can contact the top plate 311 , while the other end of the side cylinder 312 extends to the end of the side cylinder 312 away from the top plate 311 .

During the assembly process of the circuit board 320 and the fixing bracket 310, firstly, the circuit board 320 is positioned at the end of the side cylinder 312 away from the top plate 311, and then the circuit board 320 is contacted with the slope 3131 of the protrusion 313, and the circuit board 320 is aligned along the side cylinder 312. The axial direction of the upper plate 311 exerts a resisting force. Obviously, the circuit board 320 will exert force on the protrusion 313, and the protrusion 313 will be elastically deformed, and finally the circuit board 320 will slide along the slope 3131 of the protrusion 313 and enter the receiving cavity. within 315. When the circuit board 320 enters the receiving cavity 315, the circuit board 320 will be abutted and sandwiched between the pressing cylinder 314 and the protrusion 313. Obviously, the protrusion 313 exerts a supporting force on the circuit board 320 toward the top plate 311, and at the same time The pressing cylinder 314 exerts a pressing force on the circuit board 320 facing away from the top plate 311, and through the clamping effect of the pressing cylinder 314 and the locking protrusion 313 on the circuit board 320, the circuit board 320 can be well realized on the side cylinder 312. The axial positioning prevents the circuit board 320 from moving axially relative to the side cylinder 312 and improves the stability and reliability of the circuit board 320 installation.

Referring to Fig. 4, Fig. 5, Fig. 6 and Fig. 7, in some embodiments, the circuit board 320 has a front side 321 and a back side 322, both of the front side 321 and the back side 322 are actually two surfaces in the thickness direction of the circuit board 320, so The front side 321 and the back side 322 are arranged at intervals along the thickness direction of the circuit board 320 and face oppositely. The front side 321 is set facing the battery cell 400 , and the back side 322 faces away from the battery cell 400 and faces the atomizer 600 . When the circuit board 320 is accommodated in the receiving cavity 315 of the fixed bracket 310, the pressing cylinder 314 contacts the back side 322 of the circuit board 320 to apply a pressing force to the back side 322, and the locking projection 313 contacts the front side 321 of the circuit board 320 to A supporting force is applied to the front face 321 .

The circuit board 320 also has an outer peripheral surface 323, one end of the outer peripheral surface 323 is connected to the edge of the front surface 321, so that the outer peripheral surface 323 surrounds and is arranged vertically to the front surface 321, and the other end of the outer peripheral surface 323 is connected to the edge of the back surface 322, so that The outer peripheral surface 323 surrounds and is perpendicular to the back surface 322 . The outer peripheral surface 323 is recessed to a certain depth along the radial direction of the circuit board 320 to form limiting grooves 3231 . For example, the number of limiting grooves 3231 may be two, and the two limiting grooves 3231 are separated by 180° along the circumferential direction of the outer peripheral surface 323 . As another example, the number of limiting grooves 3231 may be three, and the angle between any two adjacent limiting grooves 3231 along the circumferential direction of the outer peripheral surface 323 is 120°.

The number of the limiting groove 3231 and the limiting block 316 are equal, so that the limiting groove 3231 and the limiting block 316 form a one-to-one correspondence. When the circuit board 320 is installed in the receiving cavity 315, the limiting block 316 It will cooperate with the limit groove 3231. Through the cooperation of the limiting block 316 and the limiting slot 3231 , the limiting block 316 can effectively limit the circuit board 320 in the circumferential direction, effectively preventing the circuit board 320 from rotating in the housing chamber 315 on the opposite side cylinder 312 . Therefore, under the axial clamping effect of the pressing cylinder 314 and the locking protrusion 313, the axial positioning of the circuit board 320 relative to the side cylinder 312 can be realized, and the axial movement of the circuit board 320 relative to the side cylinder 312 can be prevented; Under the cooperative action of 316 and the limiting groove 3231 , the circumferential positioning of the circuit board 320 relative to the side cylinder 312 can be realized, and the circuit board 320 can be prevented from producing circumferential rotation relative to the side cylinder 312 .

Referring to Fig. 5, Fig. 6, Fig. 7 and Fig. 8, the air pressure sensor 330 is fixed on the back side 322 of the circuit board 320, and the circuit sensor protrudes on the back side 322 along the thickness direction of the circuit board 320, so that the air pressure sensor 330 protrudes The back side 322 has a certain height. After the circuit board 320 is installed in the storage cavity 315 , the air pressure sensor 330 will be stored in the storage cavity 3141 . Since the circuit board 320 is pressed against the pressure cylinder 314, the circuit board 320 will seal the storage cavity 3141, preventing the gap between the circuit board 320 and the pressure cylinder 314 from connecting the storage cavity 315 and the storage cavity 3141 to ensure air pressure. The sensor 330 is sealed in the storage cavity 3141 relative to the storage cavity 315 . An induction hole 3111 is also opened on the top plate 311 , and the induction hole 3111 communicates with the storage chamber 3141 . The atomizer 600 and the fixing bracket 310 may have an air flow channel, and the air flow channel communicates with the sensing hole 3111 . When the user inhales at the end of the atomizer 600, negative pressure will be generated in the airflow channel. On the one hand, since the sensing hole 3111 is connected to the airflow channel, the air pressure sensor 330 will sense the existence of negative pressure in the airflow channel through the sensing hole 3111; When the air pressure sensor 330 senses negative pressure, the air pressure sensor 330 will generate a feedback signal, so that the battery 400 supplies power to the atomizer 600 according to the feedback signal, so that the e-liquid in the atomizer 600 is atomized. Obviously, when the user stops smoking, the air pressure sensor 330 cannot sense negative pressure, the battery 400 will stop supplying power to the atomizer 600, and the atomizer 600 will stop atomizing the e-liquid. On the other hand, the external air continues to enter the airflow channel under the effect of negative pressure, so that the liquid mist in the atomizer 600 carried by the air enters the user's mouth and is absorbed.

The positive elastic thimble 341 protrudes from the back side 322 of the circuit board 320. One end of the positive elastic thimble 341 is a fixed end and is fixed on the back side 322. The other end of the positive elastic thimble 341 is a free end and protrudes a certain amount relative to the back side 322. high. The positive elastic thimble 341 can be passed through the top plate 311, so that the free end of the positive elastic thimble 341 is located outside the receiving cavity 315 and protrudes relative to the top plate 311, so that the free end of the positive elastic thimble 341 and the atomizer 600 generate elasticity contact, so as to realize the electrical connection relationship between the positive elastic thimble 341 and the atomizer 600 . Similarly, the negative elastic thimble 342 protrudes from the back 322 of the circuit board 320. One end of the negative elastic thimble 342 is a fixed end and is fixed on the back 322.

The thickness of the first layer can be greater than the thickness of the second layer, the first layer can be made of brass material, the second layer can be made of gold material, and the second layer can be stacked on the first layer by electroplating process, so that Both the positive electrode sheet 510 and the negative electrode sheet 520 have reasonable mechanical strength. For example, both the positive electrode sheet 510 and the negative electrode sheet 520 have set tensile strength values and stiffness values, which are relatively high and can be To prevent the positive electrode sheet 510 and the negative electrode sheet 520 from breaking under the action of relatively large tension; and both have good electrical conductivity. The positive electrode sheet 510 is fixed on the front side 321 of the circuit board 320, and there is a reasonable connection strength between the positive electrode sheet 510 and the circuit board 320, which can prevent the positive electrode sheet 510 from detaching from the circuit board 320 under the action of a large pulling force, and also make the positive electrode sheet 510 It is electrically connected with the positive elastic thimble 341 , and at the same time, the positive electrode sheet 510 is in contact with the positive electrode portion of the battery cell 400 , so as to realize the electrical connection relationship between the positive electrode sheet 510 and the positive electrode portion. The negative electrode sheet 520 is fixed on the back side 322 of the circuit board 320, and there is a reasonable connection strength between the negative electrode sheet 520 and the circuit board 320, which can prevent the negative electrode sheet 520 from detaching from the circuit board 320 under the action of a large pulling force, and also make the negative electrode sheet 520 It is electrically connected with the negative elastic thimble 342, and at the same time, the negative electrode sheet 520 is welded to the negative electrode part of the battery cell 400, so as to realize the electrical connection between the negative electrode sheet 520 and the negative electrode part.

The middle connecting piece 523 is arranged at an angle with the first fixing piece 521 and the second fixing piece 522, for example, the middle connecting piece 523 is perpendicular to the first fixing piece 521 and the second fixing piece 522 at the same time, so that the first fixing piece 521 and the second Both the fixing pieces 522 extend along the radial direction of the cell 400 and are arranged horizontally. The first fixing piece 521 is fixed on the back surface 322 of the circuit board 320 , and the second fixing piece 522 is welded to the negative electrode piece 520 of the battery cell 400 . In other embodiments, the intermediate connecting piece may also be curved, such as S-shaped or W-shaped.

On the one hand, the battery cell 400, the electrode assembly 500 and the integrated module 300 can be recovered at the same time, specifically, a pulling force is applied to the battery cell 400, since the negative electrode sheet 520 with reasonable mechanical strength is connected to the battery cell 400 and the circuit board 320 at the same time, and Both the positive elastic thimble 341 and the negative elastic thimble 342 only form an abutting relationship with the atomizer 600 , that is, both the positive elastic thimble 341 and the negative elastic thimble 342 are not fixed in the atomizer 600 . In the process of applying tension, the negative electrode sheet 520 will not break, and the battery 400 will drive the integrated module 300 to move through the negative electrode sheet 520, so that the positive elastic thimble 341 and the negative elastic thimble 342 are far away from the atomizer 600, and then the battery 400 , the electrode assembly 500 and the entire integrated module 300 are taken out from the accommodating cavity 110 for recycling, and the battery core 400, the electrode assembly 500 and the integrated module 300 are recycled into a specific container so that the battery core 400, electrode assembly 500 and the integrated module 300 are transported to a specific place for environmental protection treatment, effectively preventing the battery cell 400 , the electrode assembly 500 and the integrated module 300 from polluting the environment, and finally improving the environmental performance of the electronic atomization device 10 . Ensure that the electronic atomization device 10 meets the environmental protection requirements of relevant countries and regions. On the other hand, only the battery cell 400 can be recycled. Specifically, the negative electrode sheet 520 is pulled hard so that the negative electrode sheet 520 is separated from the battery cell 400, thereby releasing the welding connection between the negative electrode sheet 520 and the battery cell 400. At this time, when the When the battery cell 400 exerts a pulling force, the battery cell 400 will no longer drive the integrated module 300 to move through the negative plate 520, so that the battery cell 400 is taken out from the accommodating cavity 110 for recycling, while the electrode assembly 500 and the integrated module 300 are still located in the accommodation cavity 110 .

Therefore, according to the needs of the actual situation. The battery cell 400 can be recycled separately, or the battery cell 400 , the electrode assembly 500 and the integrated module 300 can be recycled simultaneously. Since the integrated module 300 has been integrated, when the battery cell 400 drives the integrated module 300 to move through the negative plate 520, the circuit board 320, the fixing bracket 310, the air pressure sensor 330, and the positive elastic thimble 341 in the integrated module 300 can be It moves simultaneously with the negative elastic thimble 342 and other components to be taken out from the accommodating cavity 110 at one time, thereby improving the recycling efficiency of the integrated module 300 . If the components such as the circuit board 320, the fixing bracket 310, the air pressure sensor 330, the positive elastic thimble 341 and the negative elastic thimble 342 have not been integrated, in the process of recycling, each part must be recycled separately in sequence, so that Increase the frequency and labor intensity of recycling operations, which will obviously affect the recycling efficiency.
