[0051] Example:

[0052] The embodiment of the present invention provides an electronic atomization device, including a battery rod assembly and an atomizer, wherein the battery rod assembly and the atomizer are detachably connected, for example, the battery rod assembly and the atomizer are detachably connected through magnetic attraction. The battery rod assembly is used to power the atomizer, and the atomizer is used to heat and atomize to generate aerosol for the user to inhale after receiving power.

[0053] Embodiment 1:

[0054] See also Figures 1 to 6 , the atomizer includes an atomizer assembly and a base assembly. The atomizer assembly includes a support frame 1, an atomizer core 2 and an airway component 3. The support frame 1 is provided with a receiving groove 11, and the airway component 3 is assembled in the receiving groove 11. The atomizer core 2 is configured to be clamped and fixed in the receiving groove 11 by the support frame 1 and the airway component 3. The atomizer core 2 includes a heating net 21. The atomizer is provided with an electrode hole 31, and the pin 223 of the heating net 21 is at least partially in the orifice of the electrode hole 31; the base assembly can be detachably assembled on the atomizer assembly, and the base assembly includes an electrode structure 4; wherein, when the base assembly is assembled with the support frame 1, the electrode structure 4 is embedded in the electrode hole 31, and the pin 223 of the heating net 21 is pressed against the inner peripheral wall of the electrode hole 31 by the electrode structure 4.

[0055] Since the atomizer core 2 is configured to be clamped and fixed in the accommodating groove 11 by the support frame 1 and the airway component 3, the heating network 21 is fixed by clamping and is not easy to deform during assembly; moreover, when the base assembly is assembled with the support frame 1, the pins 223 of the heating network 21 are pressed against the inner wall of the electrode hole 31 by the electrode structure 4, that is, the pins 223 of the heating network 21 and the electrode structure 4 are interference fit, so that the pins 223 of the heating network 21 and the electrode structure 4 are in close contact, and the electrical connection between the pins 223 of the heating network 21 and the electrode structure 4 can avoid welding processing, thereby reducing the assembly difficulty between the atomizer assembly and the base assembly, and improving the assembly yield of the atomizer.

[0056] It should be noted that the electrode hole 31 can be set separately on the airway component 3, or it can be formed by the support frame 1 and the airway component 3. It is preferably set separately on the airway component 3. When assembling the atomization component, there is no need to consider the support frame 1 and the airway component 3 to form the electrode hole 31, which reduces the difficulty of assembly.

[0057] See also Figure 2 and Figure 3 (The dotted part in 3 is the pin of the heating network before bending). When the atomizer assembly is separated from the base assembly, the tail end of the pin 223 of the heating network 21 is in the opening of the electrode hole 31, and the tail end of the pin 223 of the heating network 21 passes over the center of the opening of the electrode hole 31, so that when the base assembly is assembled with the support frame 1, it is ensured that the electrode structure 4 can push the pin 223 of the heating network 21 into the electrode hole 31, and at the same time, there is a sufficient contact area between the electrode structure 4 and the pin 223 of the heating network 21, thereby ensuring the electrical connection effect between the electrode structure 4 and the pin 223 of the heating network 21. According to actual needs, the length of the pin 223 of the heating network 21 in the opening of the electrode hole 31 can be two-thirds, three-quarters, and five-sixths of the diameter of the electrode hole 31, and the width of the pin 223 of the heating network 21 can be half of the diameter of the electrode hole 31.

[0058] See also Figure 3 In this embodiment, the pins 223 of the heating net 21 are manually bent upwards into the opening of the electrode hole 31. Specifically, the tail ends of the pins 223 of the heating net 21 extend out of the receiving groove 11. After the airway member 3 and the support frame 1 are assembled, the pins 223 of the heating net 21 can be manually bent upwards so that the tail ends of the pins 223 of the heating net 21 are in the opening of the electrode hole 31.

[0059] See also Figure 2 and Figure 5 The electrode structure 4 is provided with two electrode members distributed at intervals, and the airway member 3 is provided with two electrode holes 31 distributed at intervals, and the center distance between the two electrode holes 31 is equal to the center distance between the two electrode members, so as to ensure that the two electrode members can be respectively embedded in the two electrode holes 31. It should be understood that the heating network 21 is provided with two pins 223, and the center distance between the two pins 223 of the heating network 21 is equal to the center distance between the two electrode holes 31.

[0060] See also Figure 1, there is a preset angle between the plane where the heating net 21 is located and the bottom end face of the support frame 1, and the preset angle ranges from 45° to 90°, such as 45°, 55°, 60°, 70°, etc., so that the heating net 21 is tilted relative to the vertical direction, which is conducive to making the support frame 1 and the airway member 3 clamp the heating net 21 more firmly. Specifically, the bottom wall of the receiving groove 11 and the side where the airway member 3 contacts the bottom wall of the receiving groove 11 are tilted, and the bottom wall of the receiving groove 11 and the side where the airway member 3 contacts the bottom wall of the receiving groove 11 are parallel to the plane where the heating net 21 is located, so as to ensure that the heating net 21 clamped by the airway member 3 and the support frame 1 is tilted. An air inlet hole 72 is provided on the base assembly, and the inclined setting of the heating network 21 can also ensure that the air inlet hole 72 is set in the center, that is, the air inlet hole 72 is in the middle area of ​​the projection formed by the heating network 21 projected in the vertical direction, so that the gas entering the atomizer from the air inlet hole 72 can carry more aerosol generated by heating and atomization of the heating network 21 to be inhaled, thereby ensuring the supply efficiency of the aerosol.

[0061] See also Figure 3 , Figure 4 and Figure 5 The support frame 1 is provided with an oil inlet hole 12 connected to the receiving groove 11, and the atomizer core 2 also includes an oil guide body 22, which is attached to the bottom wall of the receiving groove 11 and covers the oil inlet hole 12, and the oil guide body 22 and the heating net 21 are parallel to each other, and the heating net 21 is attached to the side of the oil guide body 22 away from the support frame 1, and the support frame 1, the oil guide body 22 and the airway member 3 are jointly enclosed to form an atomization chamber 23. Specifically, the oil inlet hole 12 is arranged on the bottom wall of the receiving groove 11, and the bottom wall of the receiving groove 11 is provided with a step groove 15, and the oil guide body 22 is arranged in the step groove 15, and the side of the oil guide body 22 away from the bottom wall of the receiving groove 11 is flush with the notch formed by the step groove 15 on the bottom wall of the receiving groove 11, so that the heating net 21 is horizontally and tightly attached to the surface of the oil guide body 22. The oil guide body 22 introduces the atomized oil through the oil inlet hole 12, and the heating net 21 heats the atomized oil held by the oil guide body 22 and generates an aerosol in the atomizing chamber 23; the air inlet hole 72 provided on the base assembly is connected to the atomizing chamber 23, so that the gas flowing in from the air inlet hole 72 can flow into the atomizing chamber 23 to carry the aerosol. According to actual needs, a plurality of oil inlet holes 12 can be provided, and the plurality of oil inlet holes 12 are distributed at intervals, for example, two or three oil inlet holes 12 are provided.

[0062] See also Figure 2 and Figure 4 In this embodiment, the oil-conducting body 22 can be oil-conducting cotton. In this case, the oil-conducting cotton is a cotton block. The oil-conducting cotton is directly attached to the bottom wall of the accommodating groove 11. The heating net 21 is attached to the side surface of the oil-conducting cotton away from the support frame 1. The airway component 3 presses the heating net 21 against the oil-conducting cotton, thereby achieving the clamping and fixing of the atomizer core 2 by the airway component 3 and the support frame 1.

[0063] See also Figure 4 and Figure 5 The heating net 21 includes a heating part 211 and a connecting part 222 fixed to the heating part 211. The heating part 211 is attached to the oil guide body 22, and the connecting part 222 is attached to the bottom wall of the receiving groove 11. One end of the connecting part 222 extending out of the receiving groove 11 is a pin 223 of the heating net 21. A positioning column 16 is fixed on the bottom wall of the receiving groove 11, and a positioning hole 2221 is provided on the connecting part 222. The positioning column 16 is embedded in the positioning hole 2221 so that the heating part 211 can be accurately attached to the oil guide body 22. An atomizing groove 33 is provided on the side of the airway component 3 close to the heating part 211. The atomizing groove 33 is part of the atomizing chamber 23. The width of the atomizing groove 33 on the side close to the heating part 211 is smaller than the width of the heating part 211, so that the airway component 3 can press the heating part 211 tightly to fit on the oil guide body 22.

[0064] See also Figure 1 The support frame 1 is provided with a lower oil channel 13 connected to the oil inlet hole 12. The lower oil channel 13 and the receiving groove 11 are respectively arranged on both sides of the support frame 1. The atomized oil passes through the lower oil channel 13 and the oil inlet hole 12 to be absorbed by the oil guide body 22. The plane where the lower oil channel 13 is located is arranged in parallel with the oil guide body 22, so that the distance between each oil inlet hole 12 and the lower oil channel 13, i.e., the oil guide body 22, is equal, which is conducive to ensuring balanced oil inlet. The width of the lower oil channel 13 gradually decreases along the oil discharging direction, that is, the lower oil channel 13 is a structure of being wide at the top and narrow at the bottom. On the one hand, in the oil discharging method of being wide at the top and narrow at the bottom, since the upper part of the lower oil channel 13 is wider than the lower part, the volume of the upper part of the lower oil channel 13 is larger, and the weight of the atomized oil contained is larger, which will generate a larger downward pressure, thereby facilitating the atomized oil to flow from the upper part of the lower oil channel 13 to the lower part; on the other hand, if bubbles are generated at the oil inlet hole 12, since the upper part of the lower oil channel 13 is wider, the bubbles are more likely to float upward, so that the phenomenon of bubble jamming is not easy to occur.

[0065] See also Figure 2 and Figure 5 In this embodiment, the airway member 3 and the support frame 1 are connected integrally or detachably. For example, when the airway member 3 and the support frame 1 are connected integrally, the airway member 3 and the support frame 1 can be fixed together by ultrasonic welding, laser welding, etc.; when the airway member 3 and the support frame 1 are detachably connected, the airway member 3 and the support frame 1 can be detachably connected by snap connection, screw connection, etc. According to actual needs, a buckle portion 34 can be provided on the side wall of the airway member 3, and a buckle groove 17 can be provided on the side wall of the accommodating groove 11. The detachable connection between the airway member 3 and the support frame 1 is achieved by the buckle connection between the buckle portion 34 and the buckle groove 17.

[0066] It should be noted that due to the popularity of electronic atomizers, the domestic atomizer oil production cannot meet the production needs of electronic atomizers, and atomizer oil needs to be imported from abroad; therefore, for electronic atomizers sold to foreign markets, in order to reduce product costs (such as the cost of transporting atomizer oil from abroad to China and tariff costs, etc.), the oil filling process in the production process of electronic atomizers is left abroad. However, the oil filling occurs during the assembly process of the atomizer, so the various components in the atomizer can be packaged separately and shipped for easy oil filling.

[0067] See also Figure 2 and Figure 6 In this embodiment, the atomizer also includes an oil cup 5, the atomizer assembly is provided with an oil filling hole 14, and the atomizer is provided with a blocking structure for blocking the oil filling hole 14; wherein, the blocking structure is a part of the base assembly, the atomizer assembly and the oil cup 5 are fixed to each other to form a first component, the base assembly is a second component, and the first component and the second component are both configured as independent packages, so that the first component and the second component can be shipped abroad after being separately packaged, which is convenient for subsequent filling of oil into the oil cup 5, and, after the atomizer oil is used up, the first component and the second component can be disassembled to fill oil into the oil cup 5, which is conducive to the recycling of the electronic atomization device.

[0068] Specifically, the atomizing assembly is fixed at the bottom of the oil cup 5, the support frame 1 and the oil cup 5 are enclosed together to form an oil storage cavity, the oil filling hole 14 is provided on the support frame 1 and communicates with the oil storage cavity, and oil can be filled into the oil storage cavity through the oil filling hole 14 on the support frame 1, thereby realizing oil filling at the end B of the atomizer. According to actual needs, a sealing rib 18 is provided on the peripheral side of the support frame 1, and the support frame 1 and the inner peripheral wall of the oil cup 5 are sealed and connected by the sealing rib 18.

[0069] See also Figure 2 and Figure 6 , the base assembly includes a base 6 and a sealing structure. The base 6 is detachably assembled on the bottom of the oil cup 5, for example, a buckle portion is provided on the peripheral side of the base 6, and a slot is provided on the inner peripheral wall of the oil cup 5, and the detachable assembly is achieved by the buckling connection between the buckle portion and the slot. The sealing structure includes a sealing sleeve 7 fixed to one side of the base 6, and the sealing sleeve 7 is provided with a sealing portion 71 adapted to the oil filling hole 14; wherein, the sealing sleeve 7 can be a soft rubber sleeve, such as a silicone sleeve, and the sealing sleeve 7 is convex on one side away from the base 6 to form a sealing portion 71, and when the base 6 is assembled with the oil cup 5, the base 6 pushes against the sealing portion 71 to be embedded in the oil filling hole 14 and seals the oil filling hole 14. Preferably, the length of the sealing portion 71 is greater than the length of the oil filling hole 14, so that when the sealing portion 71 is embedded in the oil filling hole 14, the sealing portion 71 extends out of the oil filling hole 14, so that the sealing portion 71 can squeeze all the atomized oil in the oil filling hole 14 into the oil storage cavity, preventing the atomized oil from remaining in excess space inside the oil filling hole 14, thereby avoiding waste of atomized oil.

[0070] See also Figure 1 and Figure 2 , the plugging sleeve 7 is sleeved on the outside of the base 6, and the sealing part 71 is hollowed out; a protrusion 61 is provided on the side of the base 6 close to the plugging sleeve 7, and the protrusion 61 is embedded in the sealing part 71. After the oil filling is completed, the oil filling hole 14 is sealed by the base assembly, specifically, the sealing part 71 is first extended into the oil filling hole 14, and then force is applied to the base 6 so that the protrusion 61 presses against the sealing part 71, and the sealing part 71 moves in the oil filling hole 14 until the top of the sealing part 71 extends out of the oil filling hole 14. At this time, the base 6 is buckled in the oil cup 5, thereby completing the assembly of the atomizer.

[0071] See also Figure 3 There are two oil filling holes 14, and the two oil filling holes 14 are distributed on both sides of the support frame 1. When filling oil, one of the two oil filling holes 14 is filled with oil, and the other is exhausted, which can ensure that the oil filling is more normal and avoid the generation of bubbles during the oil filling process. The two electrode members are fixed on the base 6, and the two electrode members are between the two oil filling holes 14. The first magnetic block 10 and the second magnetic block can be respectively set on the base 6 and the battery rod assembly, and the detachable connection between the atomizer and the battery rod assembly is realized by the magnetic attraction generated by the interaction between the first magnetic block 10 and the second magnetic block. According to actual needs, three, four, etc. oil filling holes 14 can also be set, which is conducive to improving the oil filling speed.

[0072] Embodiment 2:

[0073] See also Figure 7 and Figure 8 In this embodiment, the pin 223 of the heating net 21 can be automatically bent upward to the opening of the electrode hole 31 during the assembly process of the atomizer assembly. Specifically, the bottom wall of the accommodating groove 11 is provided with a clearance hole, and the pin 223 of the heating net 21 is attached to the bottom wall of the accommodating groove 11, and the pin 223 of the heating net 21 extends to cross the clearance hole, and the side of the airway component 3 that contacts the heating net 21 is provided with an extrusion portion 32, and the extrusion portion 32 is convexly arranged, so that the airway component 3 and the support frame 1 constitute a stamping bending structure, and the extrusion portion 32 can squeeze the pin 223 of the heating net 21 to bend upward. When the airway component 3 is assembled in the accommodating groove 11, the extrusion portion 32 extends into the clearance hole, and the pin 223 of the heating net 21 is pushed against the extrusion portion 32, so that the tail end of the pin 223 of the heating net 21 is bent upward to at least partially in the opening of the electrode hole 31.

[0074] It should be noted that when the extrusion portion 32 contacts the bottom of the clearance hole, the side of the airway component 3 on which the extrusion portion 32 is provided just contacts the bottom wall of the accommodating groove 11, so that the airway component 3 can press the heating net 21 onto the support frame 1 to ensure that the extrusion portion 32 does not interfere with the airway component 3 and the support frame 1 jointly clamping the heating net 21.

[0075] Furthermore, if Figure 7 As shown, the electrode hole 31 is arranged at the bottom end surface of the airway component 3, the extrusion portion 32 is arranged at the bottom of the airway, and one side of the extrusion portion 32 in the length direction is flush with the bottom end surface of the airway component 3, so that the pin 223 of the heating network 21 is bent upward and fits on the side of the extrusion portion 32, ensuring that the tail end of the pin 223 of the heating network 21 is in the same plane as the orifice of the electrode hole 31, thereby avoiding excessive bending of the pin 223 of the heating network 21.

[0076] It should be understood that the arrangement of other components of the atomizer in this embodiment is the same as that of other components of the atomizer in Embodiment 1, and the relevant description is not given here.

[0077] Embodiment 3:

[0078] See also Fig. 9 and Fig.10 In this embodiment, the oil guide body 22 can be a porous ceramic body, and the heating net 21 is fixed on one side surface of the porous ceramic body. When installing the porous ceramic body, it is necessary to ensure that the heating net 21 is arranged between the porous ceramic body and the airway member 3, and the airway member 3 only needs to press the porous ceramic body into the receiving groove 11, so as to achieve the clamping and fixing of the atomizing core 2 by the airway member 3 and the support frame 1; in order to prevent the porous ceramic body from shifting during installation, part of the protrusion of the porous ceramic body is arranged to be embedded in the groove on the bottom wall of the receiving groove 11.

[0079] It should be understood that the arrangement of other components of the atomizer in this embodiment is the same as that of other components of the atomizer in Embodiment 1, and the relevant description is not given here.

[0080] Embodiment 4:

[0081] See also Fig.11 and Fig.12 In this embodiment, the blocking structure and the base assembly are independently arranged. The base assembly is provided with a connecting hole connected to the oil filling hole 14, and the blocking structure is also used to block the connecting hole. The oil cup 5, the atomizing assembly and the oil cup 5 are assembled to form a first component, and the blocking structure is a second component. The first component and the second component are configured to be packaged and shipped independently, so that the first component and the second component can be shipped abroad after being packaged separately, which is convenient for the subsequent filling of oil into the oil cup 5. Moreover, after the atomizing oil is used up, the first component and the second component can be disassembled to fill the oil cup 5 with oil, which is conducive to the recycling of the electronic atomizing device.

[0082] Specifically, the base assembly includes a base 6 and a connecting sleeve 8. The base 6 is detachably assembled at the bottom of the oil cup 5; the two ends of the connecting sleeve 8 are respectively fixed to the base 6 and the atomizing assembly, and the connecting sleeve 8 can be a soft rubber sleeve, such as a silicone sleeve. One end of the connecting sleeve 8 is embedded and fixed on the support frame 1, and the other end is sleeved and fixed on the outside of the base 6, so as to connect the base assembly and the atomizing assembly. The connecting hole includes a first through hole respectively provided on the base 6 and a second through hole provided on the connecting sleeve 8. The first through hole, the second through hole and the oil injection hole 14 are connected in sequence. When the oil is injected, the atomized oil is injected into the oil storage cavity through the first through hole, the second through hole and the oil injection hole 14. The plugging structure passes through the first through hole, the second through hole and the oil injection hole 14 in sequence to seal the oil injection hole 14. The plugging structure can be a pin 9. The pin 9 extends into the oil injection hole 14 along the first through hole and the second through hole. The pin 9 is adapted to the oil injection hole 14, so that the oil injection hole 14 can be sealed.

[0083] It should be noted that the pin 9 can be a silicone part, a plastic part or a metal part, and the top end of the pin 9 extends out of the oil filling hole 14, so that the sealing part 71 can squeeze all the atomized oil in the oil filling hole 14 and transport it to the oil storage cavity, preventing the atomized oil from remaining in the excess space inside the oil filling hole 14, thereby avoiding waste of atomized oil. When the pin 9 is a metal part, a magnetic block can be set on the battery rod assembly, and the interaction between the magnetic block and the pin 9 forms a magnetic attraction, which can realize a detachable connection between the battery rod assembly and the atomizer.

[0084] It should be understood that the arrangement of other components of the atomizer in this embodiment is the same as that of other components of the atomizer in Embodiment 1, and the relevant description is not given here.

[0085] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
