The fixing bracket 310 further includes a limiting block 316, and the limiting block 316 is disposed on the inner side surface of the side tube 312 in a protruding manner and is received in the receiving cavity 315, so that the limiting block 316 protrudes a certain length along the radial direction of the side tube 312 relative to the inner side surface of the side tube 312.

In the process of assembling the circuit board 320 with the fixing bracket 310, the circuit board 320 is firstly positioned at one end of the side cylinder 312 away from the top plate 311, then the circuit board 320 is contacted with the inclined surface 3131 of the convex card 313, and a pressing force is applied to the circuit board 320 towards the top plate 311 along the axial direction of the side cylinder 312, obviously, the circuit board 320 will generate a force on the convex card 313, the convex card 313 will elastically deform, and finally the circuit board 320 will slide along the inclined surface 3131 of the convex card 313 and enter the receiving cavity 315. After the circuit board 320 enters the receiving cavity 315, the circuit board 320 abuts and is clamped between the pressing cylinder 314 and the clamping protrusion 313, obviously, the clamping protrusion 313 applies a supporting force to the circuit board 320 towards the top plate 311, the pressing cylinder 314 applies a pressing force to the circuit board 320 against the top plate 311, and by the clamping action of the pressing cylinder 314 and the clamping protrusion 313 on the circuit board 320, the positioning of the circuit board 320 in the axial direction of the side cylinder 312 can be well realized, the circuit board 320 is prevented from moving axially relative to the side cylinder 312, and the mounting stability and reliability of the circuit board 320 are improved.

Referring to fig. 4, 5, 6 and 7, in some embodiments, the circuit board 320 has a front surface 321 and a back surface 322, and both the front surface 321 and the back surface 322 are actually two surfaces in the thickness direction of the circuit board 320, so that both the front surface 321 and the back surface 322 are spaced apart and face opposite to each other in the thickness direction of the circuit board 320. The front surface 321 is disposed toward the battery cell 400, and the back surface 322 faces away from the battery cell 400 toward the atomizer 600. When the circuit board 320 is received in the receiving cavity 315 of the fixing bracket 310, the pressing cylinder 314 contacts the back surface 322 of the circuit board 320 to apply a pressing force to the back surface 322, and the locking protrusion 313 contacts the front surface 321 of the circuit board 320 to apply a supporting force to the front surface 321.

The circuit board 320 further has an outer circumferential surface 323, one end of the outer circumferential surface 323 is connected to an edge of the front surface 321 such that the outer circumferential surface 323 is disposed around and perpendicular to the front surface 321, and the other end of the outer circumferential surface 323 is connected to an edge of the rear surface 322 such that the outer circumferential surface 323 is disposed around and perpendicular to the rear surface 322. The outer circumferential surface 323 is recessed by a predetermined depth in the radial direction of the circuit board 320 to form a plurality of limiting grooves 3231, and the plurality of limiting grooves 3231 are arranged at regular intervals in the circumferential direction of the outer circumferential surface 323. For example, the number of the stopper grooves 3231 may be two, and the two stopper grooves 3231 are spaced 180 ° apart in the circumferential direction of the outer circumferential surface 323. For another example, the number of the limiting grooves 3231 may be three, and an angle between any two adjacent limiting grooves 3231 along the circumferential direction of the outer circumferential surface 323 is 120 °.

The number of the limiting grooves 3231 and the limiting blocks 316 is equal, so that the limiting grooves 3231 and the limiting blocks 316 form a one-to-one correspondence relationship, and when the circuit board 320 is installed in the accommodating cavity 315, the limiting blocks 316 are matched with the limiting grooves 3231. Through the cooperation of the limiting block 316 and the limiting groove 3231, the limiting block 316 can perform a good circumferential limiting effect on the circuit board 320, and the circuit board 320 is effectively prevented from rotating in the accommodating cavity 315 relative to the side tube 312. Therefore, under the axial clamping action of the pressing cylinder 314 and the clamping protrusions 313, the axial positioning of the circuit board 320 relative to the side cylinder 312 can be realized, and the circuit board 320 is prevented from moving axially relative to the side cylinder 312; under the matching action of the limiting block 316 and the limiting groove 3231, the circumferential positioning of the circuit board 320 relative to the side tube 312 can be realized, and the circuit board 320 is prevented from circumferentially rotating relative to the side tube 312.

The air pressure sensor 330 is fixed to the back surface 322 of the circuit board 320, and the circuit sensor is provided to protrude from the back surface 322 in the thickness direction of the circuit board 320 such that the air pressure sensor 330 protrudes from the back surface 322 by a certain height. After the circuit board 320 is mounted to the receiving cavity 315, the air pressure sensor 330 is received in the storage cavity 3141. Due to the pressing of the circuit board 320 against the pressing cylinder 314, the circuit board 320 will seal the storage cavity 3141, preventing a gap between the circuit board 320 and the pressing cylinder 314 to connect the receiving cavity 315 and the storage cavity 3141, and ensuring that the air pressure sensor 330 is sealed in the storage cavity 3141 relative to the receiving cavity 315. The top plate 311 is further provided with a sensing hole 3111, and the sensing hole 3111 is communicated with the storage cavity 3141. The atomizer 600 and the fixing bracket 310 may have an air flow passage communicating with the sensing hole 3111. When a user sucks on the end of the nebulizer 600, negative pressure will be generated in the air flow channel, and on the one hand, the air pressure sensor 330 will sense the existence of negative pressure in the air flow channel through the sensing hole 3111 in view of the fact that the sensing hole 3111 is communicated with the air flow channel; when the air pressure sensor 330 senses negative pressure, the air pressure sensor 330 will generate a feedback signal, so that the battery cell 400 supplies power to the atomizer 600 according to the feedback signal, and the tobacco tar in the atomizer 600 is atomized. Obviously, when the user stops pumping, the air pressure sensor 330 cannot sense negative pressure, the battery cell 400 will stop supplying power to the atomizer 600, and the atomizer 600 will stop atomizing the tobacco tar. On the other hand, the external air continuously enters the airflow channel under the action of the negative pressure, so that the air carries the liquid mist in the atomizer 600 into the oral cavity of the user to be absorbed.

The positive elastic spike 341 is disposed on the back 322 of the circuit board 320 in a protruding manner, one end of the positive elastic spike 341 is a fixed end and is fixed on the back 322, and the other end of the positive elastic spike 341 is a free end and protrudes a certain height relative to the back 322. The positive elastic thimble 341 can be inserted into the top plate 311, so that the free end of the positive elastic thimble 341 is located outside the accommodating cavity 315 and protrudes from the top plate 311, and then the free end of the positive elastic thimble 341 makes elastic contact with the atomizer 600, thereby achieving an electrical connection relationship between the positive elastic thimble 341 and the atomizer 600. Similarly, the negative flexible pin 342 protrudes from the back surface 322 of the circuit board 320, one end of the negative flexible pin 342 is a fixed end and is fixed on the back surface 322, and the other end of the negative flexible pin 342 is a free end and protrudes a certain height relative to the back surface 322. The negative elastic thimble 342 can be inserted into the top plate 311, so that the free end of the negative elastic thimble 342 is located outside the accommodating cavity 315 and protrudes relative to the top plate 311, and then the free end of the negative elastic thimble 342 is in elastic contact with the atomizer 600, thereby realizing the electrical connection between the negative elastic thimble 342 and the atomizer 600. Both positive elastomeric pins 341 and negative elastomeric pins 342 are spaced apart on back side 322.

By sheet-like structure, it is understood that the thickness of both the positive electrode sheet 510 and the negative electrode sheet 520 is much smaller than the length and width thereof. The positive electrode tab 510 and the negative electrode tab 520 each include a first layer and a second layer stacked on the first layer in a thickness direction of the first layer. The thickness of the first layer can be larger than that 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 overlapped on the first layer by adopting an electroplating process, so that the positive plate 510 and the negative plate 520 have reasonable mechanical strength, for example, the positive plate 510 and the negative plate 520 both have set tensile strength values and rigidity values which are relatively higher, and the positive plate 510 and the negative plate 520 can be prevented from being broken under the action of larger tensile force; and both have good conductive functions. The positive plate 510 is fixed on the front 321 of the circuit board 320, and the positive plate 510 and the circuit board 320 have reasonable connection strength, so that the positive plate 510 can be prevented from being separated from the circuit board 320 under the action of large pulling force, the positive plate 510 is electrically connected with the positive elastic thimble 341, and meanwhile, the positive plate 510 is elastically abutted against the positive part of the battery cell 400, so that the electrical connection relation between the positive plate 510 and the positive part is realized. The negative pole piece 520 is fixed on the front 321 of the circuit board 320, and reasonable connection strength is provided between the negative pole piece 520 and the circuit board 320, so that the negative pole piece 520 can be prevented from being separated from the circuit board 320 under the action of large pulling force, the negative pole piece 520 is also electrically connected with the negative elastic thimble 342, and meanwhile, the negative pole piece 520 is elastically abutted against the side surface 430 of the battery core 400, so that the negative pole piece 520 is elastically abutted against a metal shell as a negative part, and thus, the electrical connection relationship between the negative pole piece 520 and the negative part is realized. Therefore, the battery cell 400 can supply power to the atomizer 600 through the positive electrode sheet 510, the positive elastic ejector pins 341 and the negative elastic ejector pins 342.

In some embodiments, the positive electrode sheet 510 includes a base sheet 511 and a pressing sheet 512, and the positive electrode sheet 510 can be manufactured by stamping or the like. The base sheet 511 is fixed on the front 321 of the circuit board 320, a through hole 5111 is formed in the base sheet 511, the through hole 5111 is a circumferential closed structure and penetrates through the whole base sheet 511 along the thickness direction of the base sheet 511, one end of the pressing part is fixed on the hole wall of the through hole 5111, and the pressing part can press the positive electrode part of the battery cell 400.

For example, the pressing piece 512 includes a first connecting piece 5121, a second connecting piece 5122 and a third connecting piece 5123, and the first connecting piece 5121 is flat and has an end fixedly connected with the hole wall of the through hole 5111.

The first connection piece 5121 extends from the hole wall of the through hole 5111 away from the base sheet 511, and the distance from the first connection piece 5121 to the base sheet 511 gradually increases from the end where the first connection piece 5121 is connected with the base sheet 511 to the end where the first connection piece 5121 is connected with the second connection piece 5122. The third connecting piece 5123 extends from the second connecting piece 5122 close to the base piece 511, and the distance from the third connecting piece 5123 to the base piece 511 is gradually reduced by taking the extending direction of the third connecting piece 5123 away from the second connecting piece 5122 as a reference direction. In other words, the distance from the third connection piece 5123 to the base piece 511 gradually decreases from the end of the third connection piece 5123 connected to the second connection piece 5122 to the end of the third connection piece 5123 remote from the second connection piece 5122.
