Detailed Implementation

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] It should be noted that when a component is said to be "fixed" to another component, it can be directly on the other component or it can be in a middle component. When a component is said to be "connected" to another component, it can be directly connected to the other component or it may be in a middle component.

[0021] Unless otherwise defined, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used in this invention includes any and all combinations of one or more of the associated listed items.

[0022] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0023] Please refer to Figure 1 This utility model provides an electronic atomizer, including an atomizer body (not shown) and an atomizing cartridge 100, wherein the atomizing cartridge 100 is detachably connected to the atomizer body.

[0024] The atomizer body may have a shell (not shown), a battery (not shown), and a mouthpiece (not shown). The battery is housed within the shell, and the mouthpiece is connected and fixed to the shell. The shell may have a slot (not shown) into which the atomizing cartridge 100 is inserted. The bottom wall of the slot may have a magnetic element (not shown), and the atomizing cartridge 100 may have a magnetic guide. After the atomizing cartridge 100 is inserted into the slot, the magnetic guide and the magnetic element can be magnetically connected, thereby fixing the atomizing cartridge 100 in the slot. This detachable magnetic connection method does not damage the atomizer body when installing and removing the atomizing cartridge 100, allowing the atomizer body to be reused. The shell may have an air inlet channel (not shown) and an air outlet channel (not shown), both of which connect to the slot. The atomizing cartridge 100 is connected to both the air inlet and air outlet channels, and the air outlet channel is also connected to the mouthpiece. Outside air enters the atomizing cartridge 100 through the air intake channel of the outer shell. The battery powers the atomizing cartridge 100 to heat it, causing the material to be atomized stored in the atomizing cartridge 100 to be atomized at high temperature and form a mixture of particulate matter and air. The mixture flows from the air outlet channel to the mouthpiece and is inhaled by the user.

[0025] The airflow path design within a conventional atomizing cartridge is unreasonable, resulting in insufficient atomization of the material to be atomized, a low content of particulate matter mixed with the air, a bland taste when inhaled, and a poor user experience.

[0026] The atomizing bullet 100 of this utility model embodiment has a unique design that can improve the airflow path of conventional atomizing bullets 100 and enhance the user experience.

[0027] The following is a detailed description of the atomizing bullet 100 according to an embodiment of this utility model.

[0028] refer to Figures 1 to 3The atomizing cartridge 100 includes a housing 10, an atomizing base 20, and an atomizing core 30. The housing 10 has an air inlet 101, an air outlet 102, and a first annular groove 103. The first annular groove 103 surrounds the outer periphery of the housing 10, and the air outlet 102 connects the first annular groove 103 and the interior of the housing 10. The atomizing base 20 is disposed within the housing 10, and the atomizing base 20 encloses an air inlet channel 201 and an annular air passage 202, with the annular air passage 202 surrounding the air inlet channel 201. The atomizing base 20 also has an exhaust port 203 communicating with the annular air passage 202, and the exhaust port 203 communicates with the air outlet 102. The atomizing core 30 is disposed within the housing 10, connected to the atomizing base 20, and seals the annular air passage 202. The outlet of the air inlet channel 201 is opposite to and spaced apart from the atomizing core 30. The atomizing core 30 encloses a receiving cavity 301, which is used to receive the substance to be atomized. The substance to be atomized can be an oil or a paste, without restriction.

[0029] The housing 10, atomizing base 20, and atomizing core 30 are all approximately rotationally symmetrical cylindrical shapes with coincident axes. One axial end of the housing 10 is used to connect to the atomizer body. Specifically, one axial end of the housing 10 is provided with a magnetic guide, such as an iron ring 40, which can be magnetically connected to the magnetic components of the atomizer body. The other axial end of the housing 10 can be covered with a cover 50, which can be fixed to the housing 10 by snap-fit. Optionally, the outer periphery of the housing 10 is provided with a buckle 17, and the side wall of the cover 50 is provided with a groove 51 that matches the buckle 17. The cover 50 is fitted onto the outer periphery of the housing 10, and the buckle 17 engages with the groove 51 to assemble the cover 50 with the housing 10. The cover 50 closes one end of the housing 10, so that the atomizing cartridge 100 forms a whole. The outer periphery of the housing 10 may also be provided with an annular limiting rib 18, which is used to limit the limit position of the cover 50 that can move axially upward. After the atomizing bullet 100 is inserted into the slot of the atomizer body, the opening opposite the bottom wall of the first annular groove 103 is closed by the side wall of the slot, and the air outlet channel of the atomizer body connects the mouthpiece and the first annular groove 103.

[0030] The air inlet 101 of the housing 10 is located at the end where the magnetic conductor is installed. The atomizer seat 20 and the atomizer core 30 are both installed inside the housing 10. The atomizer seat 20 is set to be closer to the air inlet 101 than the atomizer core 30.

[0031] The airflow path is as follows: When the user inhales, negative pressure is generated. Air from the air intake channel of the atomizer body enters the interior of the housing 10 through the air intake hole 101 and enters the inlet of the air intake channel 201 of the atomizing seat 20. Then, it flows out from the outlet of the air intake channel 201 and blows directly onto the atomizing core 30. The atomizing core 30 heats the material to be atomized in the accommodating cavity 301 to form particles, which are then mixed with all the air, so that all the air participates in atomization. After the air and particles are mixed, atomized gas is formed. Then, the mixed gas enters the annular air channel 202 and enters the first annular groove 103 on the outer periphery of the housing 10 through the exhaust hole 203 and the air outlet hole 102. It then flows to the mouthpiece through the air outlet channel and is inhaled by the user.

[0032] In this process, the air exiting the air intake channel 201 collides with the atomizing core 30 and then returns to the annular air passage 202. Because the air directly faces the atomizing core 30, all the air participates in atomization. During atomization at the atomizing core 30, the air and particles are initially mixed. Upon returning to the annular air passage 202, the air and particles are further mixed. After the mixed gas enters the first annular groove 103 through the exhaust port 203 and the air outlet 102, the air and particles can mix again through the exhaust port 203, the air outlet 102, and the first annular groove 103. The air and particles are mixed multiple times, which improves the uniformity of particle distribution in the mixed gas. Furthermore, because the airflow path is relatively tortuous, the tortuous path can create turbulence in the airflow and prolong the mixing time of particles and air, resulting in a better mixing effect. The tortuous path also provides an appropriate amount of suction resistance. Thus, every puff inhaled by the user is a fully atomized and evenly mixed gas with a pure taste.

[0033] The atomizing cartridge 100 provided in this embodiment of the utility model has an outlet of the air intake channel 201 that is spaced apart from the atomizing core 30, an annular air passage 202 surrounding the air intake channel 201, and a first annular groove on the outer periphery of the shell 10. The air entering through the air intake channel 201 can participate in atomization, and after passing through a tortuous airflow path, the mixed gas can be fully mixed in the annular air passage 202 and the first annular groove, which improves the uniformity of particles in the mixed gas, making the user's inhalation taste pure and providing a good user experience.

[0034] Optional, see reference Figure 2 , Figure 3 and Figure 5 The shell 10 includes a first cylindrical body 11 and a first partition 12. The first partition 12 is connected to the inner wall of the first cylindrical body 11. An air inlet 101 penetrates the first partition 12. A first annular groove 103 is formed on the outer periphery of the first cylindrical body 11. An air outlet 102 penetrates the first cylindrical body 11.

[0035] The first cylinder 11 and the first partition 12 can be a single-piece structure. For example, the shell 10 can be made of plastic and integrally molded by injection molding. This single-piece structure ensures a seamless connection between the first cylinder 11 and the first partition 12, eliminating the need for sealing at the joint and resulting in a stable and high-strength overall connection. The air inlet 101, the first annular groove 103, and the air outlet 102 can be formed during injection molding or through subsequent drilling, cutting, or other processes, without limitation. The shell 10, made of plastic, offers advantages such as lightweight and low cost.

[0036] Optional, see reference Figure 2 , Figure 3 and Figure 6 The atomizing base 20 is disposed inside the first cylinder 11. The atomizing base 20 includes a second cylinder 21, a second partition 22, and a central tube 23. The second partition 22 is connected to the inner wall of the second cylinder 21, and an air intake chamber 104 is formed between the second partition 22 and the first partition 12. One end of the central tube 23 is connected to the second partition 22, and the central tube 23 is located on the side of the second partition 22 facing away from the first partition 12. The central tube 23 encloses the air intake channel 201, and an annular air passage 202 is formed between the outer peripheral surface of the central tube 23 and the inner wall of the second cylinder 21. The exhaust port 203 penetrates the second cylinder 21.

[0037] The second cylinder 21, the second partition 22, and the central tube 23 can be a single integrated structure. For example, the atomizing base 20 can be made of ceramic and integrally formed by sintering. This integrated structure ensures a seamless connection between the second cylinder 21 and the second partition 22, and between the second partition 22 and the central tube 23. There is no need to consider sealing at the joints of the two structures, and the overall connection is stable and strong. The air intake channel 201 and the exhaust port 203 can be formed during sintering or through subsequent drilling, cutting, or other processes, without limitation. During atomization, the atomizing core 30 heats up, resulting in a high temperature inside the atomizing base 20. Since the atomizing base 20 is made of ceramic, it will not produce any odor at high temperatures, ensuring that the taste of the mixed gas is free of any off-flavors.

[0038] The second partition 22 is spaced apart from the first partition 12 to form an air intake chamber 104, allowing air to enter the air intake chamber 104 through the air intake hole 101. The inlet of the air intake channel 201 is connected to the air intake chamber 104. The volume of the air intake chamber 104 is larger than the volume of the air intake hole 101. When the user inhales, the gas in the air intake chamber 104 is first drawn into the air intake channel 201 by negative pressure. The negative pressure generated in the air intake chamber 104 causes the air intake hole 101 to continuously intake air into the air intake chamber 104. The air intake chamber 104 serves to pre-store air, resulting in lower suction resistance during the initial stage of inhalation.

[0039] Optional, see reference Figure 2 and Figure 5One end of the second cylinder 21 can be connected to the first partition 12, or the first partition 12 is provided with an annular step 13, which is connected to the first cylinder 11, and one end of the second cylinder 21 is connected to the annular step 13. There is a gap between the end face of the second partition 22 and the end face of the second cylinder 21 facing the first partition 12, so that there is a gap between the second partition 22 and the first partition 12, and the second cylinder 21, the first partition 12, and the second partition 22 together form an air intake cavity 104, or the second cylinder 21, the annular step 13, the first partition 12, and the second partition 22 together form an air intake cavity 104. Providing an annular step 13 can increase the distance between the first partition 12 and the second partition 22, and / or providing a gap between the end face of the second partition 22 and the second cylinder 21, can increase the volume of the air intake cavity 104, so as to pre-store more air and improve the smoothness of the initial stage of suction.

[0040] Optional, see reference Figure 2 The inlet area of ​​the air intake channel 201 is flared. Specifically, from the first partition 12 towards the second partition 22, the inner diameter of the inlet area of ​​the air intake channel 201 gradually decreases, with the inner diameter being largest at the point where it connects with the air intake chamber 104, and gradually decreasing towards the outlet. Optionally, the inner diameter of the central tube 23 remains constant, and the air intake channel 201 is only flared in the area corresponding to the second partition 22. The flared inlet area allows air from the air intake chamber 104 to enter the air intake channel 201 more easily, improving airflow smoothness.

[0041] Optional, see reference Figure 3 and Figure 5 The first partition 12 has multiple protrusions 14 on its surface facing the second partition 22. There are multiple air inlets 101, and each air inlet 101 passes through the multiple protrusions 14 in a corresponding manner. Each air inlet 101 is misaligned with the air inlet channel 201.

[0042] By setting a protrusion 14 and allowing the air inlet 101 to pass through it, the length of the air inlet 101 can be extended. The misalignment of the air inlet 101 with the air intake channel 201 allows the air exiting the air inlet 101 to collide with the first baffle 12 and then bend back into the air intake chamber 104. This allows for adjustment of the suction resistance, ensuring it is at a suitable level and preventing air exiting the air inlet 101 from directly entering the air intake channel 201, which would result in excessively low suction resistance. It should be understood that if the suction resistance is too low, the user will experience too little resistance when inhaling, resulting in a large amount of atomized gas mixture being produced with very little suction, lacking a proper inhalation sensation. Furthermore, insufficient suction may prevent the heating function of the atomizing core 30 from activating, leading to a lack of atomization. Conversely, if the suction resistance is too high, the user will require a large amount of suction to atomize the air, increasing user fatigue. Therefore, neither excessively low nor high suction resistance can guarantee a good user experience. A reasonable suction resistance is achieved through the rational planning of the airflow path; for example, designing a winding airflow path can adjust the suction resistance.

[0043] Optional, see reference Figure 2 and Figure 3 The outer circumferential surface of the second cylinder 21 is provided with a second annular groove 204, and the exhaust port 203 and the air outlet 102 are both connected to the second annular groove 204.

[0044] The openings opposite to the bottom wall of the second annular groove 204 are sealed by the side wall of the first cylinder 11. The mixed gas from the annular air passage 202 flows out through the exhaust port 203 into the second annular groove 204, filling the annular groove. Then, it flows out through the exhaust port 102 into the first annular groove 103 and fills the first annular groove 103. In this way, by setting the second annular groove 204, the mixed gas can be thoroughly mixed again, so that the particles and air are further mixed evenly, improving the taste.

[0045] Optional, see reference Figure 2 and Figure 3 The number of exhaust holes 203 and air outlet holes 102 are both multiple and arranged at intervals along the circumference, and the multiple exhaust holes 203 and multiple air outlet holes 102 are staggered.

[0046] The number of exhaust holes 203 and air outlet holes 102 can be the same or different, without restriction. Having multiple exhaust holes 203 and air outlet holes 102 can accelerate the flow of the mixed gas from the annular channel 202 to the second annular groove 204, and from the second annular groove 204 to the first annular groove 103. Simultaneously, the staggered arrangement of the exhaust holes 203 and air outlet holes 102 ensures that the mixed gas entering the second annular groove 204 from the exhaust hole 203 must flow circumferentially a certain distance before flowing from the air outlet hole 102 to the first annular groove 103, extending the mixing time and forcing thorough mixing of the mixed gas. The tortuous flow direction also creates a certain amount of suction resistance, which helps to adjust the suction resistance to a suitable level.

[0047] The exhaust port 203 corresponds to the middle of the annular air passage 202 along the axial direction, and also roughly corresponds to the middle of the second annular groove 204 along the axial direction. The air outlet 102 roughly corresponds to the middle of the first annular groove 103 along the axial direction. The multiple exhaust ports 203 are at approximately the same height along the axial direction, and the multiple air outlets 102 are also at approximately the same height along the axial direction. The air outlet 102 roughly corresponds to one end of the second annular groove 204 near the first partition 12. That is, the multiple exhaust ports 203 and multiple air outlets 102 are also staggered along the axial direction, and the air outlet 102 is closer to the first partition 12 than the exhaust ports 203. Thus, the airflow path is more tortuous, which is beneficial for adjusting the suction resistance to a suitable level.

[0048] Optional, see reference Figure 3 and Figure 5 The outer circumferential surface of the first cylindrical body 11 is provided with a first positioning part 15, and the inner circumferential surface of the second cylindrical body 21 is provided with a second positioning part 24. The first positioning part 15 and the second positioning part 24 cooperate to fix the second cylindrical body 21 and the first cylindrical body 11 in the circumferential direction. One of the first positioning part 15 and the second positioning part 24 is a protrusion, and the other is a groove.

[0049] For example, such as Figure 3 and Figure 5 As shown, the first positioning part 15 on the inner circumferential surface of the first cylinder 11 is a protrusion, and the second positioning part 24 on the outer circumferential surface of the second cylinder 21 is a groove. Both the protrusion and the groove extend axially. When the second cylinder 21 is installed into the first cylinder 11, the protrusion and the groove are aligned. After installation, the degree of freedom of relative circumferential rotation between the second cylinder 21 and the first cylinder 11 is restricted. In this way, it can be ensured that the multiple exhaust holes 203 and the multiple air outlet holes 102 are misaligned. Therefore, the first positioning part 15 and the second positioning part 24 are provided to achieve the function of preventing mistaken identity, ensuring that the exhaust holes 203 and the air outlet holes 102 are misaligned, ensuring that the suction resistance is at an appropriate level, and that the suction resistance remains stable because the first cylinder 11 and the second cylinder 21 cannot rotate relative to each other.

[0050] Optional, see reference Figure 2 and Figure 3 The atomizing bullet 100 also includes a sealing sleeve 60. The sealing sleeve 60 is sleeved on the outer periphery of the second cylinder 21 and the atomizing core 30. One end of the sealing sleeve 60 extends into the second annular groove 204, and the other end is attached to the end face of the atomizing core 30 facing away from the second partition plate 22. The outer peripheral surface of the sealing sleeve 60 is in contact with the inner wall of the first cylinder 11.

[0051] The sealing sleeve 60 completely encloses the outer periphery of the atomizing core 30 and partially encloses the outer periphery of the second cylinder 21. Specifically, the sealing sleeve 60 is fitted onto the outer periphery of the end of the second cylinder 21 away from the first partition 12. One end of the sealing sleeve 60 extends into the second annular groove and abuts against the side wall of the second annular groove away from the first partition 12, while the other axial end of the sealing sleeve 60 extends to the end face of the atomizing core 30 away from the first partition 12. The cover 50 presses the sealing sleeve 60 axially, and because the cover 50 engages with the snap fastener 17 on the housing 10, the cover 50 can axially press and fix the atomizing core 30 and the atomizing seat 20, ensuring axial fixation. The sealing sleeve 60 can be made of a deformable material, such as silicone or rubber, which can seal gaps between structures through its own deformation. Specifically, the sealing sleeve 60 seals the end of the second annular groove axially away from the first partition plate 12, preventing the mixed gas in the second annular groove from leaking from the gap between the second cylinder 21 and the first cylinder 11 into the gap between the atomizing core 30 and the first cylinder 11. Furthermore, because the sealing sleeve 60 is deformable, it can absorb impact in the event of accidental drop or shaking, ensuring that the atomizing seat 20, atomizing core 30, and other structures are not damaged.

[0052] Optionally, the inner circumferential surface of the first sleeve is provided with a stepped surface 16, which is perpendicular to the axial direction. The end of the sealing sleeve 60 facing the first partition 12 abuts against the stepped surface 16 to enhance the sealing effect. Optionally, the outer circumferential surface of the sealing sleeve 60 is provided with an annular rib 61. The annular rib 61 can be one or multiple ribs spaced apart along the axial direction. The annular rib 61 is used to abut against the inner circumferential surface of the first sleeve to enhance the sealing effect.

[0053] Optional, see reference Figure 2 , Figure 3 and Figure 7 The atomizing core 30 includes a cup body 31 and an atomizing body 32. The cup body 31 is connected to the end of the second cylinder 21 away from the first partition 12, and the atomizing body 32 is disposed at the end of the cup body 31 facing the second partition 22. The atomizing body 32 is spaced from the central tube 23, and the cup body 31 and the atomizing body 32 together enclose the accommodating cavity 301.

[0054] The cup body 31 is roughly a rotationally symmetrical cylindrical shape, while the atomizing body 32 is roughly a circular plate shape. Both the cup body 31 and the atomizing body 32 can be made of ceramic. The cup body 31 can be made of dense ceramic, while the atomizing body 32 can be made of porous ceramic. Ceramic materials have the advantage of high temperature resistance, which can meet the requirements of high-temperature atomization, and will not produce any odor at high temperatures, ensuring a pure taste. The substance to be atomized, placed in the receiving cavity 301, can penetrate through the micropores of the atomizing body 32 to the surface of the atomizing body 32 facing the central tube 23. At high temperatures, the atomizing body 32 can atomize the substance into micro-particles, which mix with the air entering the central tube 23 to form an atomized mixed gas.

[0055] Optional, see reference Figure 2 , Figure 3 and Figure 7 The surface of the atomizing body 32 facing the central tube 23 is provided with an atomizing heating element 33, and the outer periphery of the cup body 31 is provided with a preheating heating element 34. (Reference) Figures 2 to 4 The first partition 12 is provided with a first electrode 71, a second electrode 72, and a third electrode 73. Both the second electrode 72 and the third electrode 73 are annular, with the second electrode 72 surrounding the outer periphery of the first electrode 71, and the third electrode 73 surrounding the outer periphery of the second electrode 72. The positive electrode of the atomizing heating element 33 is electrically connected to the first electrode 71, the positive electrode of the preheating heating element 34 is electrically connected to the second electrode 72, and the negative electrodes of both the atomizing heating element 33 and the preheating heating element 34 are electrically connected to the third electrode 73.

[0056] The surface of the first partition 12 facing away from the second partition 22 may have a central hole 105 and multiple annular receiving grooves 106. The multiple annular receiving grooves 106 sequentially surround the central hole 105. The first electrode 71 passes through the central hole 105, and the second electrode 72, the third electrode 73, and the aforementioned iron ring 40 are respectively received in their corresponding annular receiving grooves 106, with the iron ring 40 located on the outermost ring. (Reference) Figure 5 The first partition 12 may also have several first wiring holes 107 communicating with a portion of the annular receiving groove 106, see reference. Figure 6 The second partition 22 may also have several second wiring holes 205. The first wiring hole 107 and the second wiring hole 205 are used for wiring the corresponding wires of the atomizing heating element 33 and the preheating heating element 34. The first electrode 71, the second electrode 72, and the third electrode 73 are all exposed to the outside. After the atomizing bullet 100 is inserted into the slot, the first electrode 71, the second electrode 72, and the third electrode 73 can all contact the corresponding contacts to achieve power supply, and then transmit the power to the atomizing heating element 33 and the preheating heating element 34 through the corresponding wires.

[0057] A preheating element 34 is provided on the outer periphery of the cup body 31 to heat the cup body 31. When the substance to be atomized is, for example, a paste, heating the cup body 31 can liquefy the paste, allowing it to penetrate the atomizing body 32. The temperature at which the preheating element 34 heats the cup body 31 is lower than the heating temperature at which the atomizing element 33 heats the atomizing body 32. This lower temperature of the preheating element 34 prevents deformation of the sealing sleeve 60 on the outer periphery of the cup body 31. Both the preheating element 34 and the atomizing element 33 can be heating wires, and both can be curved and extended. The preheating element 34 can cover the entire circumferential surface of the outer periphery of the cup body 31, and the atomizing element 33 can cover most of the surface of the atomizing body 32 facing the first partition 12. The specific coverage is not limited. The negative electrodes of the preheating element 34 and the atomizing element 33 share a third electrode 73, saving one electrode and reducing costs.

[0058] Optional, see reference Figure 2 and Figure 6 A boss 25 can be provided on the inner wall of the atomizing base 20. The cup body 31 is installed on the boss 25, so that there is a gap between the outer peripheral surface of the cup body 31 and the inner wall of the atomizing base 20 on one side of the boss 25 along the circumferential direction. The wire of the preheating heating element 34 can pass through this gap and extend into the annular air passage 202, and pass through the second wiring hole 205 on the second partition 22. It should be understood that after each wire passes through the corresponding first wiring hole 107 and second wiring hole 205, the first wiring hole 107 and second wiring hole 205 can be sealed with adhesive or the like to prevent air leakage from the first wiring hole 107 and second wiring hole 205.
