[0007] The bracket has a first abutment surface, and the battery and the seal are arranged in the bracket; when the difference between the pressure of the seal at one end close to the battery and the pressure at one end away from the battery is greater than a threshold pressure, the seal is pressed against the first abutment surface, and the seal is deformed to seal the gap between the electrode column and the seal in the perforation.

[0015] In one embodiment, a mounting hole is formed on the first abutting surface; when the difference between the pressure of the seal at one end close to the battery and the pressure of the seal at one end away from the battery is greater than a threshold pressure, the seal is deformed and interference fits with the mounting hole.

[0016] In one embodiment, the sealing member includes a base portion, the through hole is provided in the base portion, the base portion has a third abutting surface, and the third abutting surface can be pressed against the first abutting surface.

[0039] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly understood.

[0040] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "inside", "outside", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0041] See also Figure 1 and Figure 2 The electronic atomization device 10 provided by one embodiment of the present invention includes an atomizer 20 and a power supply assembly 30, and the atomizer 20 is connected to the power supply assembly 30. The power supply assembly 30 is used to supply power to the atomizer 20, and the atomizer 20 converts the electrical energy into heat energy, so that the aerosol-generating matrix contained in the atomizer 20 absorbs heat and then atomizes to form smoke that can be inhaled. Figure 5 and Figure 6 The power supply assembly 30 includes a housing 110 , a bracket 200 , a seal 300 , an electrode column 410 , a mounting seat 420 , a battery 430 , a circuit board 440 and a protective cover 500 .

[0042] See also Figure 3 and Figure 4In some embodiments, the housing 110 is a substantially long cylindrical structure, and the bracket 200 is sleeved in the housing 110, that is, a portion of the cavity surrounded by the housing 110 is used to accommodate the bracket 200, and the remaining portion of the cavity surrounded by the housing 110 forms the installation cavity 101. In other words, the installation cavity 101 is surrounded by the housing 110 and the bracket 200. A portion of the atomizer 20 is accommodated in the installation cavity 101, and the remaining portion of the atomizer 20 is exposed outside the installation cavity 101 so that the user can smoke.

[0043] See also Figure 3 , Figure 4 and Figure 6 , the electronic atomization device 10 may further include a magnetic member 120, and a socket 250 is provided on the bracket 200, and the magnetic member 120 is roughly cylindrical, and the magnetic member 120 is inserted into the socket 250. When the atomizer 20 is located in the installation cavity 101, the magnetic member 120 will generate a magnetic attraction force on the atomizer 20, so as to fix the atomizer 20 on the power supply assembly 30, thereby realizing a detachable connection between the atomizer 20 and the power supply assembly 30. When the atomizer 20 needs to be unloaded from the power supply assembly 30, it is only necessary to apply a force to the part of the atomizer 20 exposed outside the installation cavity 101, so that the atomizer 20 overcomes the magnetic attraction and detaches from the bracket 200 and is pulled out of the installation cavity 101. Of course, in other embodiments, the atomizer 20 can also be detachably connected to the power supply assembly 30 by means of a threaded connection or a snap connection; the atomizer 20 and the power supply assembly 30 can also be fixed in a non-detachable connection.

[0044] See also Figure 5 and Figure 6, the circuit board 440, the mounting seat 420 and the battery 430 are all arranged in the bracket 200. Specifically, the housing 110 and the bracket 200 enclose a receiving cavity 240, and the battery 430 is located in the receiving cavity 240. The bracket 200 is provided with an exhaust hole 230, and the exhaust hole 230 connects the receiving cavity 240 with the outside. The mounting seat 420 can be roughly rectangular and mounted on the circuit board 440 through the SMT (Surface Mounted Technology) process, and the electrode column 410 is fixedly connected to the mounting seat 420. The circuit board 440 can be a printed circuit board or a flexible circuit board. One end of the circuit board 440 is connected to the mounting seat 420, and the other end of the circuit board 440 is connected to the battery 430. The electrode column 410 is electrically connected to the battery 430 through both the mounting seat 420 and the circuit board 440. When the atomizer 20 is located in the mounting cavity 101, the electrode column 410 abuts against the electrode contacts in the atomizer 20, so that the battery 430 supplies power to the atomizer 20 to atomize the aerosol generating substrate to form smoke. In other embodiments, the mounting base 420 can be omitted, and the electrode column 410 can be directly fixed on the circuit board 440.

[0045] See also Fig.11 and Fig.12 In some embodiments, the bracket 200 has a first abutting surface 210, and a mounting hole 220 is formed on the first abutting surface 210. The mounting hole 220 is disposed close to the atomizer 20. Figure 5 , the extension direction of the mounting hole 220 is the same as the extension direction of the electrode column 410, in other words, the axial direction of the mounting hole 220 is the same as the axial direction of the electrode column 410. Obviously, the side wall surface of the mounting hole 220 is connected to the first abutting surface 210, the side wall surface of the mounting hole 220 is vertically arranged, the first abutting surface 210 can be horizontally arranged, and the side wall surface and the first abutting surface 210 can be perpendicular to each other. Fig.10 and Fig.13 The mounting seat 420 has a second abutting surface 421 , and the second abutting surface 421 can also be arranged horizontally, that is, the first abutting surface 210 and the second abutting surface 421 are parallel to each other, and the electrode column 410 is connected to the mounting seat 420 and protrudes a certain length relative to the second abutting surface 421 .

[0046] See also Figure 8 , Fig. 9 and Fig.10 In some embodiments, the seal 300 is located in the bracket 200, and the seal 300 is closer to the atomizer 20 relative to the battery 430. The material of the seal 300 is a deformable material. Preferably, the seal 300 is a silicone seal 300, that is, the seal 300 is made of silicone material, so that the seal 300 has a certain flexibility and can produce elastic deformation.

[0047] The sealing member 300 includes a base portion 310, the base portion 310 has a third abutting surface 311 arranged horizontally, a receiving cavity 330 and a through hole 321 are provided on the base portion 310, the through hole 321 is provided on the third abutting surface 311, and penetrates through the top wall surface 331 surrounding the receiving cavity 330 and communicates with the receiving cavity 330, and the axial direction of the through hole 321 is the same as the axial direction of the electrode column 410. Preferably, the sealing member 300 also includes a protrusion 320, the cross-sectional dimension of the protrusion 320 is smaller than the cross-sectional dimension of the base portion 310, the protrusion 320 is connected to the third abutting surface 311 and protrudes a certain length relative to the third abutting surface 311, and the through hole 321 extends to the protrusion 320.

[0048] See also Figure 7 , Figure 8 and Fig.14 During the assembly process, the mounting seat 420 is received in the receiving cavity 330 of the base portion 310, and the second abutting surface 421 of the mounting seat 420 abuts against the top wall surface 331 surrounding the receiving cavity 330, so as to position the mounting seat 420. The electrode column 410 is inserted into the through hole 321, and the electrode column 410 can form a clearance fit with the through hole 321, or an interference fit. Fig.10 At the same time, the protrusion 320 of the sealing member 300 cooperates with the mounting hole 220 on the bracket 200, and the third abutting surface 311 and the first abutting surface 210 can abut against each other.

[0049] When the battery 430 is in a normal state, the pressure difference on the seal 300 in the extension direction (vertical direction) of the perforation 321 is less than the threshold pressure, and the seal 300 will not produce elastic deformation. When the battery 430 is in an abnormal state such as an explosion, the explosion of the battery 430 will cause the gas pressure in the bracket 200 to increase suddenly, resulting in a pressure difference acting on the seal 300 greater than the threshold pressure. Under the action of this pressure, the seal 300 produces elastic deformation, which makes the aperture of the perforation 321 smaller, and the electrode column 410 and the perforation 321 will form an interference fit with a large interference amount. In layman's terms, the seal 300 will form a "tightening" effect on the electrode column 410, thereby eliminating the gap between the electrode column 410 and the seal 300 in the perforation 321, preventing the harmful gas generated by the explosion of the battery 430 from entering the atomizer 20 through the gap and being absorbed by the user, thereby improving the safety of the electronic atomization device 10. It can also prevent the high-pressure gas in the bracket 200 from acting on the atomizer 20 through the gap, that is, prevent the high-pressure gas from generating an impact force on the atomizer 20, and prevent the impact force from overcoming the magnetic attraction and ejecting the atomizer 20 from the mounting cavity 101, and further prevent the atomizer 20 from being ejected quickly from causing harm to the user. Of course, in the case where the entire atomizer 20 forms a non-detachable connection relationship with the power supply assembly 30, the atomizer 20 can also be prevented from being ejected. In addition, since the bracket 200 is provided with an exhaust hole 230 connected to the receiving cavity 240, the high-pressure gas generated by the battery 430 can be discharged from the exhaust hole 230 to the outside, thereby realizing a rapid decompression of the receiving cavity 240, which can also improve the safety of the electronic atomization device 10. Of course, a USB interface electrically connected to the battery 430 can also be provided in the exhaust hole 230. When the USB interface is connected to an external charging device through a power cord, the charging device can charge the battery 430 through the USB interface.

[0050] When the pressure of the seal 300 is greater than the threshold pressure and the seal 300 is elastically deformed, a strong abutting force is formed between the third abutting surface 311 and the first abutting surface 210. At the same time, the protrusion 320 is deformed, so that the cross-sectional size of the protrusion 320 increases and forms an interference fit with the mounting hole 220, that is, the bracket 200 forms a "tightening" effect on the protrusion 320. On the one hand, the sealing member 300 can be prevented from rushing out of the bracket 200 under the impact of the high-pressure gas through the limiting effect of the first abutting surface 210; on the other hand, the gap between the third abutting surface 311 and the first abutting surface 210 can be eliminated, and the gap between the protrusion 320 and the bracket 200 in the mounting hole 220 can also be eliminated, so as to prevent harmful high-pressure gas from entering the atomizer 20 from the above two gaps or impacting the atomizer 20. Furthermore, since the second abutting surface 421 of the mounting seat 420 abuts against the top wall surface 331 of the accommodating cavity 330 formed on the sealing member 300, the limiting effect of the top wall surface 331 can effectively prevent the mounting seat 420 from moving toward the atomizer 20, thereby preventing the mounting seat 420 from driving the electrode column 410 to move and generating a large abutting pressure on the electrode contact in the atomizer 20. In addition, the elastic deformation generated by the sealing member 300 will also absorb the strong abutting energy between the electrode column 410 and the electrode contact, thereby preventing damage to the electrode column 410 and the electrode contact.

[0051] In some embodiments, the threshold pressure ranges from 1KPa to 2MPa, for example, the specific value of the threshold pressure may be 1KPa, 100KPa, 1.5MPa or 2MPa, etc. The threshold pressure may also range from 2KPa to 2MPa, or from 10KPa to 1MPa. When the threshold pressure is from 10KPa to 1MPa, on the one hand, it can prevent the seal 300 from deforming due to excessive suction by the user, and on the other hand, it can make the seal 300 deform in time in the early stage of the battery 200 explosion so that the electrode column 410 and the perforation 321 form an interference fit. When the pressure acting on the seal 300 is greater than the threshold pressure, the interference between the electrode column 410 and the perforation 321 is 0.01mm to 0.1mm, for example, the specific value of the interference may be 0.01mm, 0.05mm, 0.08mm or 0.1mm, etc. The larger the interference, the stronger the "tightening" effect of the seal 300 on the electrode column 410. The so-called interference may be interpreted as the difference between the diameter of the electrode column 410 and the diameter of the through hole 321 . For example, when the interference is 0.05 mm, the diameter of the electrode column 410 is 0.05 mm larger than the diameter of the through hole 321 .

[0052] See 8. Fig. 9 and Fig.10In some embodiments, the protective cover 500 can also be made of silicone material. The protective cover 500 includes a bottom plate portion 510 and a side tube portion 520. The side tube portion 520 is arranged around the bottom plate portion 510. One end of the bracket 200 close to the atomizer 20 is sleeved in the side tube portion 520, and the shell 110 is sleeved outside the side tube portion 520. In other words, the side tube portion 520 is clamped between the bracket 200 and the shell 110. A boss 521 is arranged on the surface of the side tube portion 520. The boss 521 is pressed against the inner wall surface of the shell 110, that is, the boss 521 and the cavity surrounded by the shell 110 form an interference fit, eliminating the gap between the side tube portion 520 and the shell 110, so that the boss 521 forms a sealing effect on the cavity surrounded by the shell 110, ensuring that the harmful high-pressure gas generated by the battery 430 cannot enter the atomizer 20 from the gap or impact the atomizer 20. At the same time, the bottom plate 510 covers the seal 300, and the bottom plate 510 can provide a certain degree of protection for the seal 300. The electrode column 410 is inserted into the bottom plate 510, and the electrode column 410 can maintain an interference fit with the through hole provided on the bottom plate 510, so that the protective cover 500 and the seal 300 play a double sealing role, further improving the safety performance of the electronic atomization device 10. When the atomizer 20 is located in the installation cavity 101, the bottom of the atomizer 20 can contact the bottom plate 510.

[0053] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
