In related art, the end cap assembly includes a cover body that covers the end surface of one end of the oil cup, a base that is arranged in the oil cup and located between the atomizer assembly and the end cap. Since the base is located in the oil cup as a whole, the base usually needs to be provided with a connecting structure on the side wall that is respectively connected to the atomizer assembly and the inner wall of the oil cup. In addition, in order to improve the sealing performance of the atomizer, a sealing structure is usually required between the oil cup and the base to prevent the liquid stored in the atomizer from leaking from the connection gap between the base and the inner wall of the oil cup. In this way, a larger size space of the oil cup needs to be occupied in the axial direction, making the overall axial size of the atomizer longer and having a non-compact structure.

[0023] Example:

[0024] like Figure 1-3 As shown, in an embodiment of the present application, an electronic atomization device is provided, which includes a power supply assembly and an atomizer, wherein the power supply assembly is electrically connected to the atomizer so that the power supply assembly can supply power to the atomizer. Specifically, the power supply assembly and the atomizer can be connected in a detachable or non-detachable manner. As an example, the power supply assembly and the atomizer can be connected in a detachable manner such as a snap connection, a screw connection, or a magnetic connection. It can be understood that in other embodiments, the atomizer can be an integrated structure with the power supply assembly, and the embodiment of the present application does not impose specific restrictions on this.

[0025] In some embodiments, the atomizer includes: an oil cup 1, a flexible bracket 2 fixed in the oil cup 1, an atomizer core 3 fixed on the flexible bracket 2, and a base 5 fixed to the bottom end of the oil cup 1. The oil cup 1 is provided with a liquid storage chamber 12 and an air outlet channel 13 spaced apart from each other. The liquid storage chamber 12 and the air outlet channel 13 are respectively connected to opposite sides of the atomizer core 3, and the air outlet channel 13 is also connected to the outside of the oil cup 1; a sealing portion 21 is provided at the bottom of the flexible bracket 2, and the base 5 includes a seat body 51 and a support portion 52 connected to the seat body 51 and extending toward the inside of the oil cup 1, and the sealing portion 21 is clamped between the inner side of the oil cup 1 and the support portion 52; a first limiting structure 14 is provided on the outer peripheral side of the bottom end of the oil cup 1, and a second limiting structure 53 adapted to the first limiting structure 14 is also connected to the peripheral side of the seat body 51; the first limiting structure 14 and the second limiting structure 53 are fixed by snapping.

[0026] Specifically, the base 5 can be securely fixed to the bottom side of the oil cup 1 through the snap-fitting engagement between the first limiting structure 14 and the second limiting structure 53. Furthermore, the flexible bracket 2 has a sealing portion 21, which is clamped between the inner wall of the oil cup 1 and the outer side of the support member. That is, the sealing portion 21 can respectively have an interference fit with the inner wall of the oil cup 1 and the outer side of the support portion 52, so that the sealing portion 21 is clamped between the inner wall of the oil cup 1 and the outer wall of the support portion 52, thereby sealing the connection gap between the support portion 52 and the oil cup 1 to prevent the oil (atomizing medium) in the liquid storage chamber 12 from leaking through the gap. In this embodiment, since the first limiting structure 14 of the oil cup 1 is fixed to the base 5 on the outside, and the support portion 52 of the base 5 can extend upward in the axial direction into the flexible bracket 2 and be fixed to the flexible bracket 2, the structure is simplified while ensuring sealing. This also makes the connection between the base 5, the atomizer core assembly, and the oil cup 1 more compact, which helps to reduce the axial size of the atomizer.

[0027] The oil cup 1 in this embodiment has a nozzle end a and an open end b, with a base 5 fixed to the open end b. The oil cup 1 is provided with a vent pipe 11, an air outlet channel 13 and a liquid storage chamber 12 separated by the vent pipe 11. The air outlet channel 13 is provided inside the vent pipe 11 of the oil cup 1 and connects the nozzle end a with the external environment. The space defined by the inner wall of the oil cup 1 and the vent pipe 11 forms the liquid storage chamber 12. The liquid storage chamber 12 is used to store the atomizing medium. The aerosol formed after the atomizing medium is heated and atomized can be transported from the air outlet channel 13 to the nozzle end a for inhalation by the user. The atomizing assembly is provided with an atomizing core 3, which is used to heat the atomizing medium to form an aerosol.

[0028] In this embodiment, the first retaining structure 14 includes a first retaining groove 141 formed on the outer circumference of the oil cup 1, and a first protrusion 142 connected to the first retaining groove 141 and extending radially outward. The first retaining groove 141 is adapted to engage with the second retaining structure 53, which defines a retaining hole 531 adapted to engage with the first protrusion 142. The second retaining structure 53 is embedded in the first retaining groove 141, and the first protrusion 142 engages with the retaining hole 531. The retaining hole 531 engages with the first protrusion 142, thereby restricting the relative position of the oil cup 1 and the base 5 in the axial direction. Combined with the retaining hole 531, the retaining groove 141 and the second retaining structure 53 ensure a stable connection between the oil cup 1 and the base 5. Furthermore, the precise alignment of the first retaining groove 141 and the second retaining structure 53 improves the compactness of the device connection while also enhancing the overall aesthetics of the atomizer. It is understandable that in some embodiments, a limiting hole 531 can be opened in the first limiting structure 14, and a corresponding first protrusion 142 can be set in the second limiting structure 53. The first protrusion 142 is engaged with the limiting hole 531, which can also achieve a stable connection between the oil cup 1 and the base 5. No limitation is made here.

[0029] In this embodiment, the first retaining structure 14 also includes a second protrusion 143 connected to the bottom side of the oil cup 1 and extending downward in the axial direction. The base 5, support portion 52, and second retaining structure 53 collectively form a second retaining groove 54 that mates with the second protrusion 143. The second protrusion 143 is embedded in the second retaining groove 54. The interaction between the second protrusion 143 and the second retaining groove 54 further enhances the assembly stability of the base 5 and the oil cup 1. By utilizing protrusions in different directions and corresponding retaining grooves or retaining holes, this embodiment can achieve positional control of the oil cup 1 and base 5 in various directions. This provides a stable structural connection and a clever coordination, facilitating device size reduction. Furthermore, the first protrusion 142 has a guide slope for sliding engagement with the second retaining structure 53. The guide bevel can be set on the lower side of the first protrusion 142. During installation, the oil cup 1 is pressed downward from the top of the base 5, so that the first protrusion 142 can automatically squeeze the second limiting structure 53. At the same time, the guide bevel can slide with the second limiting structure 53 to guide the second limiting structure 53 to undergo a certain elastic deformation, so that the first protrusion 142 can be quickly inserted into the limiting hole 531, which is convenient for user operation.

[0030] In this embodiment, two first limiting structures 14 are symmetrically provided, and the position and number of the second limiting structures 53 correspond to the first limiting structures 14, which has a simple structure, beautiful appearance and convenient use. Of course, in some other embodiments, more first limiting structures 14 and second limiting structures 53 can also be provided, which is not limited here. In this embodiment, as Figure 2 As shown, the bottom of the flexible bracket 2 is provided with a mounting groove adapted to the shape of the support portion 52, and the support portion 52 is at least partially inserted into the mounting groove. The mounting groove of the flexible bracket 2 can be encapsulated by the base 5, and the flexible bracket 2 can be encapsulated in the oil cup 1, so that the packaging of the atomizer can be completed. By accommodating the support portion 52 in the mounting groove, the radial and axial dimensions of the atomizer can be reduced, making the matching structure of the atomizer bracket and the base 5 more compact, and also contributing to the miniaturization design of the atomizer. Optionally, the base 5 can be provided with an air inlet 55, and external air can enter the oil cup 1 through the air inlet 55, and then enter the atomization groove 41 through the air vent 24 of the flexible bracket 2.

[0031] In this embodiment, the flexible bracket 2 is provided with a receiving groove 22, which extends through one side of the flexible bracket 2 to the air outlet passage 13. A fixing member 4 is also embedded in the receiving groove 22, and the atomizer core 3 is fixed to the fixing member 4. The atomizer core 3 is provided with an atomizing surface, and the fixing member 4 defines an atomizing groove 41 that connects the air outlet passage 13 and the atomizing surface. The atomizing surface heats the atomized liquid, atomizing it to form an aerosol, which is then released from the atomizing surface of the atomizer core 3. The atomizing surface is connected to the air outlet passage 13 through the atomizing groove 41, allowing the aerosol to flow out of the atomizing groove 41 for the user to inhale.

[0032] Further, in the present embodiment, the atomizing surface is facing the fixing member 4, and the side of the fixing member 4 facing the atomizing surface is provided with an atomizing groove 41, and the two ends of the flexible bracket 2 are respectively provided with a vent 24 and an air outlet 23 connected to the two ends of the atomizing groove 41, and the vent 24 and the avoidance port 25 are spaced apart at the end of the flexible bracket 2. The atomizing surface is arranged toward the fixing member 4, so that the atomizing surface can correspond to the atomizing groove 41. On the one hand, the atomizing groove 41 can utilize the vent 24 to input external air so that the aerosol particles formed by atomization are fully mixed with the external air in the atomizing groove 41, providing enough space for the formation of aerosol. On the other hand, the atomizing groove 41 is connected with the air outlet 23, so that the aerosol is discharged from the air outlet 23 and transported to the mouthpiece end a. In the present embodiment, the vent 24 and the avoidance port 25 are not connected to each other, and the vent 24 and the avoidance port 25 are both arranged on the bottom end face of the flexible bracket 2. Of course, in other examples, the vent 24 may also be formed as a relief opening 25 . In this way, the relief opening 25 can be used to allow the electrode column 6 to pass through and also to provide air intake.

[0033] Furthermore, in this embodiment, the atomizer core 3 also includes a liquid absorption surface facing away from the atomizing surface. A lower oil hole is provided on the side of the flexible bracket 2 away from the receiving groove 22, connecting the liquid storage chamber 12 with the liquid absorption surface. The atomizing surface and the liquid absorption surface are arranged opposite each other, which can fully utilize the space of the atomizer core 3 and make the structure of the atomizer core 3 more compact. By providing the lower oil hole, the liquid absorption surface of the atomizer core 3 can be connected to the liquid storage chamber 12. The atomizing medium in the liquid storage chamber 12 can flow into the atomizer core 3 through the lower oil hole. The liquid absorption surface absorbs the atomizing medium for heating and atomization.

[0034] In this embodiment, the flexible bracket 2 further defines a relief opening 25 that communicates with the receiving groove 22, and the fixing member 4 defines a plug interface corresponding to the relief opening 25. The base 5 is further connected to an electrode column 6, with the end of the electrode column 6, distal from the base 5, sequentially passing through the relief opening 25 and the plug interface to electrically connect to the atomizer core 3. The base 5 may also define a mounting hole compatible with the electrode column 6, so that one end of the electrode column 6 can pass from the bottom end upward through the mounting hole and the relief opening 25, then into the plug interface to achieve electrical connection with the atomizer core 3. By inserting the electrode column 6 into the plug interface, a certain overlap occurs between the electrode column 6 and the fixing member 4 along the axis of the electrode column 6. The fixing member 4 can be secured in the receiving groove 22 by the portion of the electrode column 6 inserted into the plug interface, making it difficult for the fixing member 4 to escape from the receiving groove 22. This not only ensures power to the atomizer core 3, but also stabilizes the fixing member 4, improves the compactness of the connection between the structures, and helps reduce installation space.

[0035] It is understood that in order to achieve electrical connection between the electrode column 6 and the heating element 32 of the atomizer core 3, a metal lead can be provided on the surface of the fixing member 4. One end of the metal lead can pass around the top, bottom or side surface of the fixing member 4, thereby reaching the surface of the fixing member 4 that is used to abut the atomizer core 3, so that the metal lead can contact the heating element 32 to achieve electrical connection. The other end of the metal lead is used to be provided in the plug interface, or on the surface of the fixing member 4 that is used to connect to the electrode column 6, so as to achieve electrical connection between the electrode column 6 and the heating element 32. The technology for providing a metal lead to connect the electrode column 6 and the heating element 32 is already documented in the relevant art by those skilled in the art and will not be repeated here.

[0036] In this embodiment, the fixing member 4 is provided with third limiting structures 42 on either side of the atomizer groove 41. The atomizer core 3 is provided with fourth limiting structures 33 corresponding to the third limiting structures 42. The third limiting structures 42 and the fourth limiting structures 33 interlock and mate. The third limiting structures 42 and the fourth limiting structures 33 facilitate positioning and limiting the atomizer core 3 and the fixing member 4 when assembled into the accommodating groove 22. In one embodiment, the third limiting structures 42 are protrusions, and the fourth limiting structures 33 are grooves or mating through-holes. When the two are mated, the protrusions can be inserted into the grooves or mating through-holes. This not only ensures the positioning of the fixing member 4 and the atomizer core 3, but also improves the assembly accuracy of the two. Furthermore, the interlocking of the protrusions with the grooves or mating through-holes connects the fixing member 4 to the atomizer core 3, facilitating the fixing member 4 to abut against the atomizer core 3 and preventing the two from separating. Of course, in other embodiments, the third limiting structures 42 can be grooves, and the fourth limiting structures 33 can be protrusions. Alternatively, one of the two third limiting structures 42 arranged on both sides of the atomization groove 41 is set as a groove and the other is set as a protrusion. Correspondingly, one of the fourth limiting structures 33 is set as a protrusion and the other is set as a groove. This is not limited here.

[0037] In this embodiment, if Figure 2 and 3 As shown, the atomizing core 3 includes a heating body 32 and an oil-conducting body 31 connected to the heating body 32. The oil-conducting body 31 is used to absorb and store the atomizing medium. The heating body 32 can be arranged on the surface or inside of the oil-conducting body 31. In one embodiment, the heating body 32 is fixed to the outer surface of the oil-conducting body 31, and the liquid absorption surface is located on the side of the oil-conducting body 31 away from the heating body 32, and the atomizing surface is the side where the heating body 32 is located. The heating body 32 can be electrically connected to the electrode column 6. After the connection is energized, the atomizing medium in the oil-conducting body 31 can be heated and an aerosol can be formed. The oil-conducting body 31 in this embodiment can be made of porous ceramics, porous glass, oil-conducting cotton, hemp and other materials. As Figure 3 As shown, both the heating element 32 and the oil-conducting element 31 may be provided with a fourth limiting structure 33. For example, an inwardly recessed notch may be provided on the outer edge of the oil-conducting element 31, into which the third limiting structure 42 may be inserted. The pins of the heating element 32 may be provided with through-holes. When the heating element 32 is disposed on the surface of the oil-conducting element 31, the third limiting structure 42 may pass through the through-holes and be inserted into the notch of the oil-conducting element 31.

[0038] In some embodiments, the fixing member 4 comprises a hard member. When the fixing member 4 is installed in the receiving groove 22, the outer periphery of the fixing member 4 forms an interference fit with the inner wall of the receiving groove 22, thereby sealing the fixing member 4 and the flexible bracket 2. By configuring the fixing member 4 as a hard member, the installation operation is facilitated. The interference fit between the fixing member 4 and the sidewall of the receiving groove 22 can utilize the elastic force of the flexible bracket 2 itself to create an interaction force between the outer periphery of the fixing member 4 and the sidewall of the receiving groove 22, thereby achieving a tight fit and achieving a seal, thereby simplifying the assembly process and improving assembly efficiency.

[0039] In some embodiments, the flexible bracket 2 is further provided with a ventilation hole, which is connected to the receiving tank 22, and the ventilation hole and the lower oil hole are arranged on the same side of the flexible bracket 2. The ventilation hole can allow air to enter the liquid storage chamber 12, so that the liquid storage chamber 12 can achieve internal and external air pressure balance by replenishing air after a portion of the atomized medium flows out. After the gas enters the ventilation hole, it will flow in the liquid atomized medium in the form of bubbles until the liquid surface of the atomized medium emerges. This can balance the air pressure in the liquid storage chamber 12 so that the atomized medium can continue to flow out automatically. The flexible bracket 2 has two opposite side surfaces, one of which can be used to set the receiving tank 22, and the other side is provided with a lower oil channel, which is connected to the liquid storage chamber 12. The atomized medium in the liquid storage chamber 12 can flow out through the lower oil channel and enter the atomizing core 3 located in the receiving tank 22.

[0040] In this embodiment, the electronic atomization device may further include a power supply component, which may be a battery rod. The battery rod and the base 5 and / or the oil cup 1 may be connected and fixed by mutual plugging, threaded connection or snap connection. The power supply component is used to be electrically connected to the electrode column 6 to provide electrical energy for the operation of the atomization core 3.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
