Description

Technical Field

[0001] This application relates to the field of atomization technology, and in particular to an electronic atomizer. Background Technology

[0002] In conventional e-cigarettes, the male and female fasteners and the anti-reverse stop are core structural elements ensuring the stability and sealing of the shell assembly. However, their combination requires a thickness of three shell material layers to achieve the desired functionality. The male and female fasteners are used to secure the shell assembly. The female fastener needs a sufficient groove to accommodate the male fastener, and this groove depth must be at least one shell material layer. The male fastener, to ensure fastening strength and durability, also requires a thickness of one material layer. The anti-reverse stop, to compensate for the gap after the male and female fasteners are joined and improve the shell's sealing and structural flatness, requires a height of one shell material layer for its protrusion or recess.

[0003] Typically, the base material thickness of an e-cigarette atomizer shell is 0.8~1.2mm. When three such thicknesses are stacked, the male / female snap fastener and reverse stop structure alone occupy 2.4~3.6mm of space. This difference directly affects the radial diameter or axial length of the shell assembly, increasing the overall size of the e-cigarette. This not only impacts the atomizer's portability but also limits the flexibility of layout for internal components such as the battery and coil. Furthermore, it increases the material usage and production cost of the shell assembly, contradicting the current trend of miniaturized and lightweight e-cigarettes. Utility Model Content

[0004] The main objective of this application is to provide an electronic atomizer that specifically addresses the technical problem of bulky overall size in conventional electronic atomizers, where the shell components require multiple layers of material to achieve a tight connection.

[0005] To achieve the above objectives, this application proposes an electronic atomizer, the electronic atomizer including a housing assembly, the housing assembly comprising: A first outer casing has a connecting hole and a connecting notch on one side. One side of the connecting notch penetrates the wall of the first outer casing in a first direction, which is perpendicular to the thickness direction of the first outer casing. The second outer shell has an inner wall that is detachably connected to the outer wall of the first outer shell. The inner wall of the second outer shell is provided with a first connecting protrusion and a second connecting protrusion. The first connecting protrusion can enter or exit the connecting hole along the thickness direction of the first outer shell, and the second connecting protrusion can enter or exit the connecting notch along a direction parallel to the first direction. When the first housing and the second housing are connected, the first connecting protrusion is completely located within the connecting hole, and the wall of the connecting hole can prevent the first connecting protrusion from leaving the connecting hole in a direction parallel to the first direction. The second connecting protrusion is completely located within the connecting notch, and the wall of the connecting notch can prevent the second connecting protrusion from leaving the connecting notch in the thickness direction of the first housing.

[0006] Optionally, the first connecting protrusion is inserted into the connecting hole, the size of the first connecting protrusion is less than or equal to the size of the connecting hole, the first connecting protrusion is wedge-shaped, and the height of the first connecting protrusion increases along the first direction.

[0007] Optionally, the length of the first connecting protrusion in the first direction is less than its length in the second direction, the second direction is perpendicular to the first direction, and the second direction is perpendicular to the thickness direction of the first housing; the length of the second connecting protrusion in the first direction is greater than its length in the second direction.

[0008] Optionally, the second connecting protrusion is engaged with the connecting notch, and both the connecting notch and the second connecting protrusion are gradually widened in the direction away from the second housing.

[0009] Optionally, the second connecting convex is smoothly connected to any two adjacent surfaces of the surface parallel to the first direction.

[0010] Optionally, a notch is provided on the side of the second connecting protrusion away from the second housing. The notch extends through both sides of the second connecting protrusion in a direction parallel to the first direction, and the bottom of the notch is smoothly connected to the wall of the notch.

[0011] Optionally, the top of the housing assembly has a suction port, and the bottom or peripheral surface of the housing assembly has closely spaced air inlets and clearance ports. The electronic atomizer includes: The main body is disposed within the housing assembly, and an air passage is formed inside the main body, the air passage connecting the suction port and the air inlet; and An air regulating component is slidably installed between the housing component and the main body. The air regulating component can slide parallel to a third direction to open or close the communication between the air passage and the air inlet. The air regulating component includes a sliding plate and an operating member. The sliding plate has a connecting hole. The operating member is connected to the side of the sliding plate facing the housing component and is exposed in the clearance opening. The operating member and the connecting hole are arranged in a direction different from the third direction. The connecting hole coincides with or intersects with the air inlet during the movement of the air regulating component.

[0012] Optionally, the air inlet is located in the middle of the bottom surface of the housing assembly, and the portion of the air passage near the air inlet extends vertically in a straight line.

[0013] Optionally, the top of the housing assembly has a suction port, and the bottom surface of the housing assembly near the edge has a charging port. The electronic atomizer includes: An atomizing component is disposed within the housing assembly. The bottom surface of the atomizing component has an opening, and the interior of the atomizing component forms a mist outlet channel that connects the opening and the suction port. The bottom surface of the atomizing component is recessed upward to form an annular ventilation groove, which is located around the opening. An electronic control component is disposed within the housing assembly and located below the atomizing component. An air cavity is formed between the electronic control component and the atomizing component. The port and the ventilation groove are both connected to the air cavity. A sensing channel is formed within the electronic control component, connecting the air cavity and the charging port. The bottom end of the charging port is opposite to the bottom end of the sensing channel. The sensing channel extends vertically in a straight line, and the top end of the sensing channel is partially opposite to the ventilation groove. An airflow sensor is disposed in the sensing channel, and the two sides of the airflow sensor are respectively connected to the suction port and the charging port.

[0014] Optionally, the electronic atomizer includes: A liquid suction element is disposed inside the air cavity, and the liquid suction element is located below the air vent.

[0015] In the electronic atomizer of this application, a dual limiting structure of connecting hole and connecting notch is used. Specifically, the wall of the connecting hole prevents the first connecting protrusion from leaving the connecting hole in a direction parallel to the first direction, and the wall of the connecting notch prevents the second connecting protrusion from leaving the connecting notch in the thickness direction of the first outer shell. This achieves a balance between material thickness reduction and structural reliability. More importantly, this design can reserve more space for the liquid storage tank within the same product size, significantly increasing the liquid storage capacity.

[0016] Specifically, this dual-limiting design requires only two layers of the outer shell material thickness to meet structural reliability requirements. Compared to the conventional design's three layers, this allows for the conversion of the saved two-layer wall thickness into increased storage space without expanding the overall product dimensions. This reduces the frequency of refilling, extending single-use lifespan, without sacrificing the product's compact and portable characteristics. Maintaining the original storage volume allows for further reduction in product size, better meeting market demands for slimmer devices. Simultaneously, this design increases storage capacity without compromising structural stability; the dual-directional limiting effectively prevents shell loosening and seal failure, ensuring the storage compartment's tightness. Furthermore, the reduced material thickness decreases shell material usage, lowering manufacturing costs and achieving multiple technological advantages: reliability, portability, large capacity, and low cost.

[0023] This application discloses an electronic atomizer, comprising a first housing and a second housing. A connecting hole and a connecting notch are formed on one side of the first housing. One side of the connecting notch penetrates the wall of the first housing in a first direction, perpendicular to the thickness direction of the first housing. The inner wall of the second housing is detachably connected to the outer wall of the first housing. The inner wall of the second housing has a first connecting protrusion and a second connecting protrusion. The first connecting protrusion can enter or exit the connecting hole along the thickness direction of the first housing, and the second connecting protrusion can enter or exit the connecting notch along a direction parallel to the first direction. When the first and second housings are connected, the first connecting protrusion is completely located within the connecting hole, and the wall of the connecting hole prevents the first connecting protrusion from leaving the connecting hole along the direction parallel to the first direction. The second connecting protrusion is completely located within the connecting notch, and the wall of the connecting notch prevents the second connecting protrusion from leaving the connecting notch along the thickness direction of the first housing.

[0024] In the electronic atomizer of this application, a dual limiting structure of connecting hole and connecting notch is used. Specifically, the wall of the connecting hole prevents the first connecting protrusion from leaving the connecting hole in a direction parallel to the first direction, and the wall of the connecting notch prevents the second connecting protrusion from leaving the connecting notch along the thickness direction of the first outer shell. This achieves a balance between reduced material thickness and structural reliability. More importantly, this design allows for more space for the liquid reservoir within the same product size, significantly increasing the liquid storage capacity. Specifically, this dual limiting design requires only two layers of the outer shell's basic material thickness to meet structural reliability requirements. Compared to the conventional design's three layers, the saved two wall thicknesses on both sides can be converted into increased liquid reservoir space without increasing the overall product size. This allows users to reduce the frequency of refilling, extending the battery life per use, without sacrificing the product's compact and portable characteristics. If the original liquid storage capacity remains unchanged, the product size can be further reduced, better meeting the market demand for thinner and lighter devices. Meanwhile, this design increases the liquid storage capacity without compromising structural stability. The dual-directional limiting effectively prevents the shell from loosening and the seal from failing, ensuring the sealing of the liquid storage compartment. In addition, the reduced material thickness also reduces the amount of shell material used, lowering manufacturing costs and achieving multiple technical advantages of "reliability, portability, large capacity, and low cost".

[0025] Please combine Figures 1 to 11 The following will mainly describe the specific structure of the electronic atomizer 1.

[0026] The electronic atomizer 1 of this application includes a housing assembly 10, which includes a first outer shell 11 and a second outer shell 12. The first outer shell 11 and the second outer shell 12 can be arranged vertically or horizontally, or left-rightly, without specific limitation. The first outer shell 11 and the second outer shell 12 can be cylindrical, sheet-like, or semi-enclosed cylindrical (e.g., ...). Figure 1 (as shown), etc., are not specifically limited.

[0027] The first outer shell 11 approaches the second outer shell 12 along a first direction and is detachably connected to the second outer shell 12. The first direction is a direction perpendicular to the thickness direction of the first outer shell 11. In some embodiments, the first outer shell 11 is connected to the inner side of the second outer shell 12, that is, the inner wall of the second outer shell 12 is detachably connected to the outer wall of the first outer shell 11.

[0028] A connecting notch 112 is provided on one side of the first outer casing 11 (the portion connecting to the second outer casing 12), and one side of the connecting notch 112 penetrates through the wall of the first outer casing 11 in a first direction. A second connecting protrusion 122 is provided on the inner wall of the second outer casing 12, and the second connecting protrusion 122 can enter or exit the connecting notch 112 in a direction parallel to the first direction. In other words, the second connecting protrusion 122 enters or exits the connecting notch 112 from the notch side of the connecting notch 112.

[0029] When the first outer shell 11 and the second outer shell 12 are connected, the second connecting protrusion 122 is completely located within the connecting notch 112, and the wall of the connecting notch 112 can prevent the second connecting protrusion 122 from leaving the connecting notch 112 along the thickness direction of the first outer shell 11. Specifically, the second connecting protrusion 122 is engaged with the connecting notch 112, and both the connecting notch 112 and the second connecting protrusion 122 are gradually widened in the direction away from the second outer shell 12.

[0030] A connecting hole 111 is provided on one side of the first outer shell 11 (the part that connects to the second outer shell 12), and a first connecting protrusion 121 is provided on the inner wall of the second outer shell 12. The first connecting protrusion 121 can enter or exit the connecting hole 111 along the thickness direction of the first outer shell 11. After the second connecting protrusion 122 and the connecting notch 112 are connected and positioned, the first connecting protrusion 121 is pressed into the connecting hole 111.

[0031] When the first outer shell 11 and the second outer shell 12 are connected, the first connecting protrusion 121 is completely located within the connecting hole 111. The wall of the connecting hole 111 is circumferentially closed, preventing the first connecting protrusion 121 from leaving the connecting hole 111 in any direction other than the thickness direction of the first outer shell 11. More specifically, the wall of the connecting hole 111 prevents the first connecting protrusion 121 from leaving the connecting hole 111 in a direction parallel to the first direction. The shape of the connecting hole 111 can be square, circular, polygonal, elliptical, or irregular, etc.

[0032] In the electronic atomizer 1 of this application, a dual limiting structure of connecting hole 111 and connecting notch 112 is used. Specifically, the wall of connecting hole 111 prevents the first connecting protrusion 121 from leaving the connecting hole 111 in a direction parallel to the first direction, and the wall of connecting notch 112 prevents the second connecting protrusion 122 from leaving the connecting notch 112 along the thickness direction of the first outer shell 11. This achieves a balance between material thickness reduction and structural reliability. More importantly, this design allows for more space for the liquid storage chamber within the same product size, significantly increasing the liquid storage capacity. Specifically, this dual limiting design requires only two layers of the outer shell's basic material thickness to meet structural reliability requirements. Compared to the conventional design's three layers, it converts the saved two wall thicknesses on both sides into increased liquid storage space without expanding the overall product size. This allows users to reduce the frequency of refilling, extending the battery life per use, without sacrificing the product's compact and portable characteristics. If the original liquid storage capacity remains unchanged, the product size can be further reduced, better meeting the market's demand for thinner and lighter devices. Meanwhile, this design increases the liquid storage capacity without compromising structural stability. The dual-directional limiting effectively prevents the shell from loosening and the seal from failing, ensuring the sealing of the liquid storage compartment. In addition, the reduced material thickness also reduces the amount of shell material used, lowering manufacturing costs and achieving multiple technical advantages of "reliability, portability, large capacity, and low cost".

[0033] In some embodiments, the first connecting protrusion 121 is inserted into the connecting hole 111. The size of the first connecting protrusion 121 is less than or equal to the size of the connecting hole 111. The first connecting protrusion 121 is wedge-shaped, and the height of the first connecting protrusion 121 (the height in the thickness direction of the second housing 12) increases along the first direction. The second housing 12 is separated from the first housing 11 along the first direction. The above arrangement makes the contact area between the connecting hole 111 and the first connecting protrusion 121 relatively large. Through the cooperation between the wedge-shaped first connecting protrusion 121 and the connecting hole 111, when the housing assembly 10 is subjected to continuous tensile force or alternating load along the first direction, a self-locking effect will be generated due to the increase of the contact area with the force, which can effectively resist the risk of loosening under long-term dynamic load. The design of the first connecting protrusion 121 having a size less than or equal to the size of the connecting hole 111, combined with the wedge-shaped surface of the first connecting protrusion 121, can accommodate a certain range of manufacturing tolerances. Even if there are slight dimensional deviations or positional offsets in the connecting hole 111, the wedge-shaped surface of the first connecting protrusion 121 can still guide the first connecting protrusion 121 into the connecting hole 111 through the automatic calibration effect during assembly.

[0034] The length of the first connecting protrusion 121 in the first direction is less than its length in the second direction, and the second direction is perpendicular to the first direction and the thickness direction of the first housing 11. The length of the second connecting protrusion 122 in the first direction is greater than its length in the second direction. The second connecting protrusion 122 is longer in the first direction, and its extended length can serve as a guide rod to guide the second housing 12 to precisely fit with the first housing 11 along the first direction during assembly, reducing misalignment during docking. The length directions of the first connecting protrusion 121 and the second connecting protrusion 122 are different. Through the differentiated design of the first connecting protrusion 121 and the second connecting protrusion 122, the connection strength can be maximized within a limited space, avoiding structural redundancy.

[0035] The second connecting protrusion 122 smoothly transitions to any two adjacent surfaces of the surface parallel to the first direction. This smooth transition between adjacent parallel surfaces reduces the risk of jamming during assembly. Even with slight deviations in the insertion angle, the smoothly transitioned surface can automatically correct its position through sliding at the contact point, reducing assembly resistance. The smooth transition design allows force to be uniformly transmitted along the surface, reducing local stress peaks and improving the durability of the second connecting protrusion 122 under long-term dynamic loads.

[0036] The second connecting protrusion 122 has a notch 123 on the side opposite to the second outer shell 12, and the notch 123 extends through both sides of the second connecting protrusion 122 in a direction parallel to the first direction. The notch 123 creates an elastic structure at the free end of the second connecting protrusion 122 (the side opposite to the second outer shell 12). When the second connecting protrusion 122 is inserted into the connecting notch 112, if there is a slight dimensional deviation, the flanges on both sides of the notch 123 can undergo slight elastic contraction along a dimension perpendicular to the first direction, thereby reducing the insertion resistance. After complete assembly, the elastic deformation recovers, and the second connecting protrusion 122 fits tightly against the inner wall of the connecting notch 112, ensuring a tight connection and avoiding damage to parts caused by hard contact. The bottom of the notch 123 smoothly transitions to the wall of the notch 123, thereby avoiding stress concentration and effectively resisting material fatigue.

[0037] The housing assembly 10 has a suction port 13 at its top and an air inlet 14 on its bottom or circumferential surface. The electronic atomizer 1 includes a main body disposed within the housing assembly 10. An air passage 20 is formed inside the main body, connecting the suction port 13 and the air inlet 14. In some embodiments, the main body includes an atomizing assembly 30 and an electronic control assembly 50. The atomizing assembly 30 has an opening 31 on its bottom surface and an outlet channel 33 inside, connecting the opening 31 and the suction port 13. The electronic control assembly 50 is located below the atomizing assembly 30, and an air chamber 40 is formed between the electronic control assembly 50 and the atomizing assembly 30. The opening 31 connects to the air chamber 40, and a suction channel 52 is formed inside the electronic control assembly 50, connecting to the air inlet 14. The air passage 20 is formed by the suction channel 52, the air chamber 40, the opening 31, and the outlet channel 33.

[0038] The bottom or peripheral surface of the housing assembly 10 has a clearance opening 15 located near the air inlet 14. The electronic atomizer 1 includes a gas regulating assembly 60, which is slidably installed between the housing assembly 10 and the main body (specifically, the electronic control assembly 50). The gas regulating assembly 60 can slide parallel to a third direction to open or close the connection between the air passage 20 and the air inlet 14. The gas regulating assembly 60 includes a sliding plate 61 and an operating component 63. The sliding plate 61 and the operating component 63 can be integrally formed or detachably connected. The sliding plate 61 has a connecting hole 62. The operating component 63 is connected to the side of the sliding plate 61 facing the housing assembly 10 and is exposed in the clearance opening 15. The operating component 63 and the connecting hole 62 are arranged in a direction different from the third direction, that is, the operating component 63 and the connecting hole 62 are not on the same straight line. The connecting hole 62 coincides with or intersects with the air inlet 14 during the movement of the gas regulating assembly 60. The non-collinear (not on the same straight line) design allows the operating component 63 and the connecting hole 62 to plan paths in different directions. During the design process, there is no need to reserve a long-distance channel on the same straight line for the operating component 63 and the connecting hole 62, which can free up design space for other core components.

[0039] The operating element 63 and the connecting hole 62 are arranged non-collinearly, eliminating the design constraint of reserving a long straight channel for both. This means that the air inlet 14 does not need to be limited to the edge area of ​​the bottom surface of the housing assembly 10. Combined with the conventional layout of the atomizing assembly 30 (mostly located on the axis of the housing assembly 10, with the corresponding mist outlet 33 also located on the axis), the air inlet 14 can be flexibly opened in the area near the middle of the bottom surface of the housing assembly 10. Consequently, the air passage 20 does not need to be designed with an additional curved structure to accommodate the position of the air inlet 14, and its suction passage 52 portion near the air inlet 14 can extend directly in a straight vertical direction. In some embodiments, the air inlet 14 is opened in the middle of the bottom surface of the housing assembly 10, and the portion of the air passage 20 near the air inlet 14 extends in a straight vertical direction. As a result, the gas flow is smoother and the flow rate is more stable.

[0040] A charging port 16 is provided near the edge of the bottom surface of the housing assembly 10. An annular ventilation groove 32 is recessed upwards on the bottom surface of the atomizing assembly 30, located around the opening 31 and connecting to the air chamber 40. A sensing channel 51 is formed within the electronic control assembly 50, connecting the air chamber 40 and the charging port 16. The electronic atomizer 1 includes an airflow sensor 70, located within the sensing channel 51. The airflow sensor 70 is connected to the inhalation port 13 and the charging port 16 on both sides. The ventilation groove 32 prevents condensate or atomizing matrix flowing out of the opening 31 from easily reaching the airflow sensor 70, thus reducing the risk of damage. Air intake through the charging port 16 eliminates the need for an additional air intake on the housing assembly 10. The charging port 16 performs both charging and air intake functions, resulting in a compact structure for the electronic atomizer 1 and reduced production costs. The top of the sensor channel 51 can be aligned with a portion of the venting groove 32, thereby allowing for smoother gas flow.

[0041] The electronic atomizer 1 includes a liquid suction element 80 disposed within the air chamber 40, located below the air passage 32. Thus, condensate or atomizing matrix flowing out through the opening 31 is absorbed by the liquid suction element 80 and does not flow to the airflow sensor 70 and the electronic control component 50, thereby reducing the risk of liquid damage to the electronic components of the airflow sensor 70 and the electronic control component 50.
