1 , 2 and 3 , an electronic atomization device 10 provided in one embodiment of the present invention includes a housing 100 , a bottom cover 200 , an integrated module 300 , a battery cell 400 , an electrode assembly 500 and an atomizer 600 .

In some embodiments, the housing 100 is a substantially cylindrical tube-shaped structure, and the housing 100 is surrounded by a receiving cavity 110, which is used to receive the bottom cover 200, the battery cell 400, the integrated module 300, the electrode assembly 500, and the atomizer 600. For example, the bottom cover 200 and the atomizer 600 can be at least partially received in the receiving cavity 110, while the battery cell 400, the integrated module 300, and the electrode assembly 500 can be fully received in the receiving cavity 110. The bottom cover 200 is loaded into the receiving cavity 110 from one end of the housing 100, and the bottom cover 200 and the housing 100 form a detachable connection. When the bottom cover 200 is assembled on the housing 100, the bottom cover 200 will close the receiving cavity 110; when the bottom cover 200 is unloaded from the housing 100, the bottom cover 200 will open the receiving cavity 110. The atomizer 600 is loaded into the accommodating cavity 110 from the other end of the housing 100. The atomizer 600, the integrated module 300 and the battery cell 400 are arranged in sequence along the axial direction of the housing 100. The battery cell 400 is relatively closest to the bottom cover 200, and the integrated module 300 is located between the atomizer 600 and the battery cell 400. The battery cell 400 is used to power the atomizer 600, and the atomizer 600 converts the electrical energy into thermal energy, so that the liquid tobacco oil stored in the atomizer 600 absorbs heat and rises to the atomization temperature, and finally the tobacco oil that rises to the atomization temperature is atomized to form liquid mist that can be inhaled by the user, and the user can inhale the liquid mist at the end of the atomizer 600.

Referring to FIG. 6, FIG. 7 and FIG. 8, in some embodiments, the integrated module 300 includes a fixed bracket 310, a circuit board 320, an air pressure sensor 330, a positive elastic ejector pin 341 and a negative elastic ejector pin 342. The fixed bracket 310 is fixedly received in the accommodating cavity 110. For example, the fixed bracket 310 can be interference-fitted with the accommodating cavity 110, thereby realizing an interference connection relationship between the fixed bracket 310 and the housing 100. The fixed bracket 310 includes a top plate 311, a side tube 312 and a clamping protrusion 313. The top plate 311 is a roughly circular plate-shaped structure, and the side tube 312 is roughly cylindrical. The cylindrical structure of the side tube 312 is connected to the edge of the top plate 311 at one end, so that the side tube 312 is arranged around the top plate 311, and the top plate 311 closes one end of the side tube 312, and then the top plate 311 and the side tube 312 together enclose a receiving chamber 315. In the case where the fixed bracket 310 exists alone, since the other end of the side tube 312 is not closed, the receiving chamber 315 is actually an open chamber. The clamping protrusion 313 is arranged at one end of the side tube 312 away from the top plate 311, so that the clamping protrusion 313 and the top plate 311 are spaced a certain distance along the axial direction of the side tube 312. The clamping protrusion 313 is located in the receiving chamber 315, and the clamping protrusion 313 protrudes and is connected to the inner side surface of the side tube 312, so that the clamping protrusion 313 protrudes a certain length relative to the inner side surface of the side tube 312 along the radial direction of the side tube 312. The number of the clamping protrusion 313 can be multiple, and the multiple clamping protrusions 313 are evenly spaced along the circumference of the side tube 312. For example, the number of the protrusions 313 may be two, and the two protrusions 313 are spaced 180° along the circumference of the side tube 312. For another example, the number of the protrusions 313 may be three, and the angle between any two adjacent protrusions 313 along the circumference of the side tube 312 is 120°. The protrusion 313 has an inclined surface 3131, and the inclined surface 3131 is inclined at a certain angle relative to the axial direction of the side tube 312, for example, the inclined angle of the inclined surface 3131 relative to the side tube 312 is an acute angle.

The fixed bracket 310 also includes a pressing cylinder 314, which is a circumferentially closed cylindrical structure. The pressing cylinder 314 is located in the receiving chamber 315. One end of the pressing cylinder 314 is a fixed end and is fixed on the top plate 311, and 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. When the fixed bracket 310 exists alone, the top plate 311 and the pressing cylinder 314 together form a circumferentially closed storage chamber 3141. Obviously, the storage chamber 3141 is an open chamber with an open end, so that the storage chamber 3141 is connected to the receiving chamber 315.

The fixing bracket 310 also includes a stopper 316, which is protrudingly arranged on the inner side of the side tube 312 and accommodated in the accommodating chamber 315, so that the stopper 316 protrudes a certain length along the radial direction of the side tube 312 relative to the inner side of the side tube 312. The stopper 316 can have a certain length along the axial direction of the side tube 312, for example, one end of the side tube 312 can contact the top plate 311, and the other end of the side tube 312 extends to the end of the side tube 312 away from the top plate 311. The number of the stopper 316 can be multiple, and the multiple stopper 316 is evenly spaced along the circumference of the side tube 312. For example, the number of the stopper 316 can be two, and the two stopper 316 are spaced 180° along the circumference of the side tube 312. For another example, the number of the stopper 316 can be three, and the angle between any two adjacent stopper 316 along the circumference of the side tube 312 is 120°.

During the assembly process of the circuit board 320 and the fixing bracket 310, the circuit board 320 is first positioned at the end of the side tube 312 away from the top plate 311, and then the circuit board 320 is brought into contact with the inclined surface 3131 of the locking protrusion 313. The circuit board 320 is pressed against the top plate 311 along the axial direction of the side tube 312. Obviously, the circuit board 320 will exert a force on the clamping protrusion 313, and the clamping protrusion 313 will be elastically deformed, so that the circuit board 320 will slide along the inclined surface 3131 of the clamping protrusion 313 and enter the receiving cavity 315. After the circuit board 320 enters the receiving cavity 315, the circuit board 320 will be abutted and sandwiched between the pressing tube 314 and the clamping protrusion 313. Obviously, the clamping protrusion 313 exerts a supporting force on the circuit board 320 toward the top plate 311, and the pressing tube 314 exerts a pressing force on the circuit board 320 away from the top plate 311. Through the clamping action of the pressing tube 314 and the clamping protrusion 313 on the circuit board 320, the circuit board 320 can be well positioned in the axial direction of the side tube 312, and the circuit board 320 can be prevented from axially moving relative to the side tube 312, thereby improving the stability and reliability of the installation of the circuit board 320.

Referring to FIG. 4 , FIG. 5 , FIG. 6 and FIG. 7 , in some embodiments, the circuit board 320 has a front face 321 and a back face 322 , and the front face 321 and the back face 322 are actually two surfaces in the thickness direction of the circuit board 320 , so the front face 321 and the back face 322 are arranged at intervals along the thickness direction of the circuit board 320 and face in opposite directions. The front face 321 faces the battery cell 400 , and the back face 322 faces away from the battery cell 400 and faces 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 face 322 of the circuit board 320 and applies a pressing force to the back face 322 , and the clamping protrusion 313 contacts the front face 321 of the circuit board 320 and applies a supporting force 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 perpendicular 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 arranged 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 a limiting groove 3231, and the number of the limiting grooves 3231 can be multiple, and the multiple limiting grooves 3231 are evenly spaced along the circumference of the outer peripheral surface 323. For example, the number of the limiting grooves 3231 can be two, and the two limiting grooves 3231 are spaced 180° along the circumference of the outer peripheral surface 323. For another example, the number of the limiting grooves 3231 can be three, and the angle between any two adjacent limiting grooves 3231 along the circumference of the outer peripheral 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. When the circuit board 320 is installed in the receiving cavity 315, the limiting blocks 316 will cooperate with the limiting grooves 3231. Through the cooperation between the limiting blocks 316 and the limiting grooves 3231, the limiting blocks 316 can effectively limit the circuit board 320 in the circumferential direction, effectively preventing the circuit board 320 from rotating relative to the side cylinder 312 in the receiving cavity 315. Therefore, under the axial clamping effect of the pressing cylinder 314 and the clamping protrusion 313, the circuit board 320 can be effectively prevented from rotating relative to the side cylinder 312 in the receiving cavity 315. Under the cooperation of the limit block 316 and the limit groove 3231, the circumferential positioning of the circuit board 320 relative to the side tube 312 can be achieved, and the circuit board 320 can be prevented from circumferentially rotating relative to the side tube 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 is protruded on the back side 322 along the thickness direction of the circuit board 320, so that the air pressure sensor 330 protrudes a certain height from the back side 322. After the circuit board 320 is installed in the receiving cavity 315, the air pressure sensor 330 will be received in the storage cavity 3141. In view of the fact that the circuit board 320 and the pressing cylinder 314 are pressed against each other, the circuit board 320 will seal the storage cavity 3141, prevent the circuit board 320 and the pressing cylinder 314 from having a gap connecting the receiving cavity 315 and the storage cavity 3141, and ensure that the air pressure sensor 330 is sealed in the storage cavity 3141 relative to the receiving cavity 315. A sensing hole 3111 is also provided on the top plate 311, and the sensing hole 3111 is connected to the storage cavity 3141. The atomizer 600 and the fixed bracket 310 may have an air flow channel, and the air flow channel is connected to the sensing hole 3111. When the user draws air at the end of the atomizer 600, negative pressure will be generated in the air flow channel. On the one hand, since the sensing hole 3111 is connected to the air flow channel, the air pressure sensor 330 will sense the existence of negative pressure in the air flow channel through the sensing hole 3111; when the air pressure sensor 330 senses the negative pressure, the air pressure sensor 330 will generate a feedback signal, so that the battery 400 will power the atomizer 600 according to the feedback signal, so that the smoke oil in the atomizer 600 is atomized. Obviously, when the user stops drawing air, the air pressure sensor 330 cannot sense the negative pressure, the battery 400 will stop powering the atomizer 600, and the atomizer 600 will stop atomizing the smoke oil. On the other hand, the external gas continues to enter the air flow channel under the action of negative pressure, so that the gas carries the liquid mist in the atomizer 600 into the user's mouth and is absorbed.

The positive elastic ejector pin 341 is protrudingly arranged on the back side 322 of the circuit board 320, one end of the positive elastic ejector pin 341 is a fixed end and is fixed on the back side 322, and the other end of the positive elastic ejector pin 341 is a free end and protrudes a certain height relative to the back side 322. The positive elastic ejector pin 341 can be inserted into the top plate 311, so that the free end of the positive elastic ejector pin 341 is located outside the receiving cavity 315 and protrudes relative to the top plate 311, and then the free end of the positive elastic ejector pin 341 is in elastic contact with the atomizer 600, thereby realizing the electrical connection relationship between the positive elastic ejector pin 341 and the atomizer 600. Similarly, the negative elastic ejector pin 342 is protrudingly arranged on the back side 322 of the circuit board 320, one end of the negative elastic ejector pin 342 is a fixed end and is fixed on the back side 322, and the other end of the negative elastic ejector pin 342 is a free end and protrudes a certain height relative to the back side 322. The negative elastic ejector pin 342 can be inserted into the top plate 311 so that the free end of the negative elastic ejector pin 342 is located outside the receiving cavity 315. The negative elastic ejector pin 342 is protruded relative to the top plate 311, so that the free end of the negative elastic ejector pin 342 is in elastic contact with the atomizer 600, thereby realizing the electrical connection between the negative elastic ejector pin 342 and the atomizer 600. The positive elastic ejector pin 341 and the negative elastic ejector pin 342 are spaced apart on the back surface 322.

Referring to FIG. 2 , FIG. 3 and FIG. 4 , in some embodiments, the battery cell 400 has a top surface 410 and a bottom surface 420, which are two surfaces in the axial direction of the battery cell 400. The top surface 410 and the bottom surface 420 are spaced apart and face opposite directions in the axial direction of the battery cell 400. The top surface 410 faces the circuit board 320, and the bottom surface 420 faces away from the circuit board 320 and faces the bottom cover 200. The battery cell 400 includes a positive electrode portion and a negative electrode portion, the positive electrode portion is on the top surface 410, and the negative electrode portion is arranged on the bottom surface 420.

Referring to FIG. 5, FIG. 6, FIG. 7 and FIG. 8, in some embodiments, the electrode assembly 500 includes a positive electrode sheet 510 and a negative electrode sheet 520, and both the positive electrode sheet 510 and the negative electrode sheet 520 are strip-shaped sheet structures. The so-called sheet structure can be understood as the thickness of both the positive electrode sheet 510 and the negative electrode sheet 520 being much smaller than their length and width. The positive electrode sheet 510 and the negative electrode sheet 520 each include a first layer and a second layer, and the second layer is stacked on the first layer along the thickness direction of the first layer. The thickness of the first layer can be greater than that of the second layer. The first layer can be made of brass material, and the second layer can be made of gold material. 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 and stiffness values, which are relatively high, and can prevent the positive electrode sheet 510 and the negative electrode sheet 520 from breaking under a large tensile force; and both have good conductive function. 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 being separated from the circuit board 320 under a large tensile force, and also make the positive electrode sheet 510 electrically connected to the positive elastic ejector pin 341, and at the same time, the positive electrode sheet 510 abuts against the positive electrode part of the battery cell 400, thereby realizing the electrical connection relationship between the positive electrode sheet 510 and the positive electrode part. The negative electrode sheet 520 is fixed on the back side 322 of the circuit board 320. The negative electrode sheet 520 and the circuit board 320 have a reasonable connection strength, which can prevent the negative electrode sheet 520 from being separated from the circuit board 320 under the action of a large pulling force, and also make the negative electrode sheet 520 electrically connected to the negative elastic ejector pin 342. At the same time, the negative electrode sheet 520 is welded to the negative electrode part of the battery cell 400, thereby realizing the electrical connection relationship between the negative electrode sheet 520 and the negative electrode part. The welding of the negative electrode part of the negative electrode sheet 520 can be electric welding or the like. Therefore, the battery cell 400 can power the atomizer 600 through the positive electrode sheet 510, the positive electrode sheet 510, the positive elastic ejector pin 341 and the negative elastic ejector pin 342.

In some embodiments, the positive electrode sheet 510 includes a base sheet 511 and a pressing sheet 512. The substrate 511 is fixed to the front side 321 of the circuit board 320 , and a through hole 5111 is provided on the substrate 511 . The through hole 5111 is a circumferentially closed structure and penetrates the entire substrate 511 along the thickness direction of the substrate 511 . One end of the pressing portion is fixed to the hole wall of the through hole 5111 , and the pressing portion can press the positive electrode 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. The first connecting piece 5121 is in a flat plate shape and its end is fixedly connected to the hole wall of the through hole 5111. The second connecting piece 5122 is in a curved shape and connected between the first connecting piece 5121 and the third connecting piece 5123. The third connecting piece 5123 is in a flat plate shape and its end is connected to the second connecting piece 5122. The other end of the third connecting piece 5123 is a free end, and the second connecting piece 5122 is in contact with the positive electrode portion. The first connecting piece 5121 extends away from the hole wall of the through hole 5111 away from the base piece 511. From the end where the first connecting piece 5121 is connected to the base piece 511 to the end where the first connecting piece 5121 is connected to the second connecting piece 5122, the distance from the first connecting piece 5121 to the base piece 511 gradually increases. 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 gradually decreases, with the extending direction of the third connecting piece 5123 away from the second connecting piece 5122 as the reference direction. In other words, the distance from the third connecting piece 5123 to the base piece 511 gradually decreases from the end where the third connecting piece 5123 is connected to the second connecting piece 5122 to the end where the third connecting piece 5123 is away from the second connecting piece 5122. As a result, the pressing piece 512 is roughly V-shaped and has a certain elasticity, so that the curved second connecting piece 5122 always forms a stable and reliable abutting relationship and electrical connection relationship with the positive electrode portion.

In some embodiments, the negative electrode sheet 520 includes a first fixing sheet 521, a second fixing sheet 522 and an intermediate connecting sheet 523, wherein the intermediate connecting sheet 523 is vertically arranged along the axial direction of the battery cell 400, and the intermediate connecting sheet 523 is connected between the first fixing sheet 521 and the second fixing sheet 522, that is, one end of the intermediate connecting sheet 523 is connected to the first fixing sheet 521, and the other end of the intermediate connecting sheet 523 is connected to the second fixing sheet 522. The intermediate connecting sheet 523 is arranged at an angle with the first fixing sheet 521 and the second fixing sheet 522, for example, the intermediate connecting sheet 523 is perpendicular to the first fixing sheet 521 and the second fixing sheet 522 at the same time, so that both the first fixing sheet 521 and the second fixing sheet 522 are horizontally arranged along the radial direction of the battery cell 400. The first fixing sheet 521 is fixed to the back side 322 of the circuit board 320, and the second fixing sheet 522 is welded and connected to the negative electrode sheet 520 of the battery cell 400. In other embodiments, the intermediate connecting sheet can also be curved, for example, S-shaped or W-shaped.

The intermediate connecting piece 523 is located between the housing 100 and the battery cell 400. The first fixing piece 521 is fixedly connected to the back surface 322 of the circuit board 320. At this time, a through hole 3121 can be opened on the side tube 312 of the fixing bracket 310, and the first fixing piece 521 is inserted into the through hole 3121, so that the through hole 3121 provides a good avoidance space for the installation of the first fixing piece 521.

Since the bottom cover 200 is detachably connected to the outer shell 100, the bottom cover 200 can be removed from the outer shell 100 after all the smoke oil in the electronic atomization device 10 is consumed and before the electronic atomization device 10 is discarded. On the one hand, the battery cell 400, the electrode assembly 500 and the integrated module 300 can be recycled 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 connects the battery cell 400 and the circuit board 320 at the same time, and the positive elastic ejector pin 341 and the negative elastic ejector pin 342 only form an abutting relationship with the atomizer 600, that is, the positive elastic ejector pin 341 and the negative elastic ejector pin 342 are not fixed in the atomizer 600, in this way, in the process of applying a pulling force to the battery cell 400, the negative electrode sheet 520 will not break, and the battery cell 400 will drive the integrated module through the negative electrode sheet 520. 300 moves, so that the positive elastic ejector pin 341 and the negative elastic ejector pin 342 are away from the atomizer 600, and then the battery cell 400, the electrode assembly 500 and the entire integrated module 300 are taken out from the accommodating cavity 110 for recycling, and the battery cell 400, the electrode assembly 500 and the integrated module 300 are recycled into a specific container, so that the battery cell 400, the 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 protection 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 to separate the negative electrode sheet 520 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 pulling force is applied to the battery cell 400, the battery cell 400 will no longer drive the integrated module 300 to move through the negative electrode sheet 520, so that the battery cell 400 is taken out of the accommodating cavity 110 alone for recycling, while the electrode assembly 500 and the integrated module 300 are still located in the accommodating cavity 110.

Therefore, it can be recycled according to 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 at the same time. Since the integrated module 300 has been integrated into one, when the battery cell 400 drives the integrated module 300 to move through the negative electrode sheet 520, the circuit board 320, the fixing bracket 310, the air pressure sensor 330, the positive elastic ejector pin 341 and the negative elastic ejector pin 342 in the integrated module 300 can be moved at the same time to remove the negative electrode 520 from the accommodating cavity 110 at one time. The integrated module 300 can be removed, 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 ejector pin 341 and the negative elastic ejector pin 342 are not integrated, each component must be recycled separately in sequence during the recycling process, thereby increasing the number of recycling operations and the labor intensity, which obviously affects the recycling efficiency.
