[0003] For electronic suction devices, the stability of suction resistance is a crucial factor affecting the user's suction experience. Related technologies typically achieve suction resistance control by creating holes in the silicone component. However, silicone components are prone to deformation, leading to changes in the hole size and consequently altering the suction resistance, thus impacting the user experience. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model is implemented as follows: an electronic atomizing device includes: an oil cup having a mouthpiece end and a connecting end that are longitudinally opposite each other; an atomizing component disposed within the oil cup, the atomizing component defining an atomizing air passage that extends at least partially from the connecting end to the mouthpiece end; and an end component disposed within the connecting end of the oil cup, the end component including an elastic seal and a reinforcement, wherein the outer periphery of the elastic seal is in sealing contact with the inner peripheral wall of the connecting end, the elastic seal has an air inlet portion with an air inlet hole protruding from the side facing the atomizing component, the air inlet hole communicating with the atomizing air passage, and the reinforcement is sleeved on the outer periphery of the air inlet portion to provide the air inlet portion with resistance to the radial extrusive deformation force exerted on the air inlet portion by the inner wall of the oil cup.

[0006] Furthermore, the elastic seal includes a first end wall and a first side wall arranged around the outer periphery of the first end wall. The first side wall and the first end wall enclose a receiving cavity. An air inlet is protruding from one side of the receiving cavity on the first end wall. The outer peripheries of the first side wall and the first end wall are in sealing contact with the inner side wall of the connecting end.

The second end wall has a protective part arranged around the outer periphery of the clearance hole, and the protective part is sleeved on the outer periphery of the air inlet.

[0007] Furthermore, the reinforcement also includes a second sidewall arranged around the outer periphery of the second end wall, the second sidewall abutting against the inner side of the first sidewall, so that the first sidewall is clamped between the inner sidewall and the second sidewall of the connecting end.

[0008] Furthermore, the protective part extends axially and protrudes from the end of the air intake.

[0009] Furthermore, the reinforcing component and the elastic seal are integrally molded.

[0010] Furthermore, the reinforcing components are made of hard metal materials.

[0011] Furthermore, the cross-sectional area of ​​the air inlet is smaller than the cross-sectional area of ​​the outlet.

[0012] Furthermore, the air intake is cone-shaped.

[0013] Furthermore, the atomizing component includes an air duct and an atomizing core disposed within the air duct; wherein, a liquid storage chamber is defined between the outer side of the air duct and the oil cup, which is connected to the atomizing core for liquid flow, and an atomizing air passage is defined on the inner side of the air duct, which is connected to the air inlet and the mouthpiece end, and the atomizing air passage is arranged laterally offset from the air inlet.

[0015] Compared with the prior art, the beneficial effects of the electronic atomizing device of this utility model are as follows: an air inlet protruding from the surface is provided on one side of the elastic seal, and a reinforcing member is sleeved on the outside of the air inlet. Through the supporting effect of the heating element on the elastic seal, the radial squeezing effect of the inner side wall of the oil cup connection end on the elastic seal is reduced when it is in contact with the elastic seal.

[0024] Example:

[0025] like Figures 1 to 4As shown, in this embodiment, the electronic atomizing device includes: an oil cup 1, an atomizing component, and an end component. The oil cup 1 has a mouthpiece end 11 and a connecting end 12 that are longitudinally opposite each other. The atomizing component 3 is disposed in the oil cup 1 and defines an atomizing air passage 341 that extends at least partially from the connecting end 12 to the mouthpiece end 11. The end component is disposed in the connecting end 12 of the oil cup 1 and includes an elastic seal 2 and a reinforcement 4. The outer periphery of the elastic seal 2 is in sealing contact with the inner peripheral wall of the connecting end 12. The elastic seal 2 has an air inlet portion 24 with an air inlet hole 241 protruding from the side facing the atomizing component 3. The air inlet hole 241 is connected to the atomizing air passage 341. The reinforcement 4 is sleeved on the outer periphery of the air inlet portion 24 to provide the air inlet portion 24 with resistance to the radial extrusion deformation force of the inner wall of the oil cup 1 on the air inlet portion 24.

[0026] Specifically, in some embodiments of this example, the elastic seal 2 can be a silicone part. The elastic seal 2 is interference-fitted onto the oil cup 1 to ensure the sealing stability between the oil cup 1 and the elastic seal 2. An air inlet 24 protruding from the surface is provided on one side of the elastic seal 2, and a reinforcement 4 is fitted onto the outside of the air inlet 24. The support provided by the reinforcement 4 to the elastic seal 2 reduces the radial compression of the elastic seal 2 when the inner wall of the connecting end 12 of the oil cup 1 mates with the elastic seal 2. This effectively prevents the deformation of the elastic seal 2 from affecting the draw resistance, thus improving the draw resistance stability of the electronic atomizing device.

[0027] In some specific embodiments, an air intake channel corresponding to the air intake hole 241 can be provided in the electronic atomizing device, so that the air intake hole 241 can be connected to the outside through the air intake channel, and both ends of the airflow channel of the atomizing component 3 can be connected to the outside gas respectively. After the atomizing component 3 generates aerosol in the airflow channel, the aerosol can be smoothly carried out of the electronic atomizing device.

[0028] In this embodiment, the electronic atomizing device further includes a battery assembly 5, which includes a housing 7, a support 6 disposed within the housing 7, and a battery. The housing 7 defines a receiving cavity at one end of the support 6, and the battery is located at the end of the support 6 facing away from the receiving cavity. The oil cup 1 is disposed within the receiving cavity, and the mouthpiece 11 is located outside the receiving cavity. The atomizing component 3 is electrically connected to the battery. Specifically, the electronic atomizing device also includes a housing 7 forming a receiving cavity, within which the oil cup 1 and the support 6 are fixed. Fixing the oil cup 1 and the support 6 together with the housing 7 improves the assembly stability of the oil cup 1 and the support 6, protects the oil cup 1, the support 6, the battery assembly 55, and other structures, and also enhances the aesthetics of the electronic atomizing device. In this embodiment, the battery assembly 55 includes a battery and a circuit assembly electrically connected to the battery. A conductive connection 33 can be electrically connected to the circuit assembly, allowing the circuit assembly to control the operation of the atomizing component 3 through the conductive connection 33.

[0029] In this embodiment, as Figure 3 and 4 As shown, the elastic seal 2 includes a first end wall 21 and a first side wall 22 arranged around the outer periphery of the first end wall 21. The first side wall 22 and the first end wall 21 enclose a receiving cavity 23. An air inlet 24 protrudes from one side of the receiving cavity 23 from the first end wall 21. The outer peripheries of both the first side wall 22 and the first end wall 21 are in sealing contact with the inner side wall of the oil cup 1. The reinforcement 4 includes a second end wall 41, which is placed inside the receiving cavity 23 and has a clearance hole for the air inlet 24 to pass through. The second end wall 41 has a protective part 42 arranged around the outer periphery of the clearance hole, and the protective part 42 is sleeved on the outer periphery of the air inlet 24. Specifically, the reinforcement 4 is nested inside the receiving cavity 23 and is tightly attached to the bottom of the groove of the receiving cavity 23, which helps to improve the structural stability and assembly stability of the elastic seal 2. The outer periphery of the air inlet 24 is also tightly surrounded by the protective part 42, making the structure of the air inlet 24 more stable.

[0030] Furthermore, such as Figure 3 and 4 As shown, in this embodiment, the reinforcing member 4 further includes a second sidewall 43 arranged around the outer periphery of the second end wall 41. The second sidewall 43 abuts against the inner side of the first sidewall 22, so that the first sidewall 22 is clamped between the inner sidewall of the connecting end 12 and the second sidewall 43. That is, the second sidewall 43 is bent and connected to the outer periphery of the second end wall 41, and the entire inner wall of the accommodating cavity 23 is in close contact with the reinforcing member 4. The first sidewall 22 of the elastic seal 2 is clamped between the inner sidewall of the connecting end 12 and the second sidewall 43. This arrangement is beneficial to improving the sealing performance and assembly stability between the elastic seal 2 and the connecting end 12.

[0031] In some embodiments, the cross-sectional area of ​​the inlet end of the air inlet 241 is smaller than the cross-sectional area of ​​the outlet end, which is beneficial to increasing the air intake speed; in some preferred embodiments, the air inlet 241 can also be configured as a conical structure, which is beneficial to improving the smoothness of airflow.

[0032] In some embodiments of this example, the reinforcing member 4 is integrally formed with the elastic seal 2, simplifying the material forming and processing. The reinforcing member 4 is made of a hard metal material; specifically, it can be iron, nickel, stainless steel, etc., and is not limited thereto.

[0033] In this embodiment, the protective portion 42 extends axially and protrudes from the end of the air inlet portion 24; this effectively prevents liquid leakage from entering the air inlet hole 241 and the air inlet channel, thus affecting the suction effect. Further, in some specific embodiments, the length of the protruding portion of the protective portion 42 on the elastic seal 2 is 1.5~2.5 mm. Specifically, in the vertical direction, the length of the protective portion 42 protruding from the top side of the elastic seal 2 can be set to 1.5 mm, 1.7 mm, 1.8 mm, 2.0 mm, 2.2 mm, etc., and is not limited here.

[0034] In some specific embodiments, the reinforcement 4 can be a steel sheet, with a ring of steel sheets added inside the receiving hole. The steel sheet has good strength and hardness, is not easily deformed, and can effectively protect the receiving hole of the elastic seal 2 from deformation, thereby achieving precise and effective control of suction resistance.

[0035] In this embodiment, a guide slope is formed inside the air inlet 241. Specifically, the air intake channel can be disposed between the housing 7, the bracket 6, and the elastic seal 2. Chamfers or buffer structures can be provided at the turning points in the air intake channel and the air inlet 241 to form a guide slope, which makes the flow of gas in the air intake channel and the air inlet 241 smoother and can effectively avoid airflow noise during use.

[0036] In this embodiment, the outer side of the oil cup 1 near the connecting end 12 is fitted and connected to the inner wall of the bracket 6 facing the oil cup 1. A limiting groove is formed on the outer side of the connecting end 12 and the inner wall of the bracket 6 facing the oil cup 1, and a limiting block corresponding to the limiting groove is provided on the other side. The limiting block is embedded in the limiting groove. The connecting end 12 and the bracket 6 are fixed by a snap-fit ​​connection, which provides good fixing effect and convenient installation, reducing the risk of the protective part 42 falling out of the elastic seal 2 due to separation of the bracket 6 from the connecting end 12. Specifically, one limiting groove or multiple limiting grooves can be provided, and correspondingly, one limiting block or multiple limiting blocks can be provided, without limitation. It should be understood that when multiple sets of limiting blocks and limiting grooves are provided, all limiting blocks can be set on the connecting end 12 and all limiting grooves can be opened on the bracket 6; alternatively, all limiting blocks can be set on the bracket 6 and all limiting grooves can be opened on the connecting end 12; alternatively, some limiting blocks and some limiting grooves can be set on the connecting end 12, and another set of limiting blocks and another set of limiting grooves can be set on the bracket 6, so that the positions and structural dimensions of each set of limiting blocks and limiting grooves correspond, and no restrictions are imposed here. In some embodiments of this example, the bracket 6 can be provided with a chamfered structure on the end facing the connecting end 12, so that the connecting end 12 and the bracket 6 can be fitted and fixed more easily during installation. In some embodiments of this example, the limiting blocks can also be provided with a chamfered structure, so that the limiting blocks can enter the corresponding limiting grooves more smoothly during installation.

[0037] In this embodiment, the atomizing component 3 includes an air duct 34 and an atomizing core disposed within the air duct 34; wherein, a liquid storage chamber 13 is defined between the outer side of the air duct 34 and the oil cup 1, which communicates with the atomizing core for liquid flow, and an atomizing air passage 341 is defined on the inner side of the air duct 34, which communicates with the air inlet 241 and the mouthpiece end 11, and the atomizing air passage 341 is arranged laterally offset from the air inlet 241.

[0038] In some embodiments, such as Figure 2 As shown, the liquid storage chamber may be equipped with a liquid storage cotton to reduce the risk of leakage; in some alternative embodiments, the liquid storage chamber may not be equipped with a liquid storage cotton, such as... Figure 1 As shown.

[0039] Specifically, the atomizing air passage 341 of the electronic atomizing device includes an air outlet channel and an atomizing chamber that are interconnected. The end of the air outlet channel away from the atomizing chamber is connected to the air outlet 1111 at the top of the oil cup 1. The atomizing chamber is connected to the air inlet 241 and the air outlet channel; for example... Figure 1 and 2 As shown, the atomizing chamber is arranged laterally, offset from the air inlet 241, which helps to reduce the risk of leakage. The atomizing assembly 3 also includes a heating element 31 fixed to one side of the atomizing chamber, and the heating element 31 is connected to the conductive connection part 33.

[0040] In some specific embodiments, the nozzle end 11 of the oil cup 1 includes a nozzle component 111 and a nozzle silicone plug 112. The nozzle silicone plug 112 is connected between the nozzle component 111 and the oil cup 1, which can improve the sealing stability between the nozzle component 111 and the oil cup 1. The nozzle component 111 has an outlet 1111 that communicates with the air outlet channel. In this embodiment, the heating element 31 can be a ceramic heating wire, and the conductive connection part 33 can be an electrode connected to the heating element 31. The ceramic heating wire can be connected to the circuit structure in the battery assembly 55 through the electrode to achieve heating. Furthermore, in the atomization chamber, the atomized liquid can be converted into an aerosol by heating the heating element 31. The generated aerosol can mix with the air entering from the air inlet 241 of the air inlet channel, and reach the air outlet channel along the atomization chamber, and finally be discharged from the air outlet 1111 for user use.

[0041] In this embodiment, the atomizing component 3 further includes a liquid guide 32. Both the air outlet channel and the atomizing chamber are formed within the vent pipe 34. The liquid guide 32 is fixed between the heating element 31 and the liquid inlet. The vent pipe 34 and the inner wall of the oil cup 1 together enclose a liquid storage chamber 13 that communicates with the liquid inlet. In this embodiment, the vent pipe 34 can be a one-piece structure or a structure assembled from multiple discrete components; no limitation is made here. The atomizing liquid can be stored in the liquid storage chamber 13. When the electronic atomizing device is working, the atomizing liquid can reach the liquid guide 32 along the liquid inlet, then pass through the liquid guide 32 to reach the heating element 31, and then be heated and atomized to form an aerosol.
