Description
TECHNICAL FIELD
[0001] The utility model belongs to electronic atomization technical field, especially electronic atomization device. BACKGROUND

Although this design can meet the use in normal situations, if the product falls from a high place during use, the heating body is easy to be impacted and loosened from the sealing silica gel, and the spring sheet may be broken due to over contact. In addition, both sides of the ultra-thin plane heating body are circuit connection contact areas, and when the product is impacted from different angles, the heating body is easy to be deformed, the sealing is ineffective, and the contact is disconnected, so that the customer continues to use the product, and oil leakage or circuit disconnection occurs.

In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0029] Example:
[0030] like Figures 1-6 As shown, in this embodiment, the electronic atomizing device includes: an oil cup 1, an atomizing component fixed inside the oil cup 1, and a base 6 fixed to the bottom side of the atomizing component. The base 6 is provided with an electrode 5. The atomizing component includes an elastic sealing member 3 fixed inside the oil cup 1, a heating element 2 fixed on the elastic sealing member 3, and a conductive member 4 connecting the heating element 2 and the base 6. An atomizing cavity 11 is formed between the heating element 2, the conductive member 4, and the base 6. The oil cup 1 is also provided with an air inlet channel and an air outlet channel 12 that respectively connect the atomizing cavity 11 and the outside. The conductive member 4 includes a fixing part 41 connected to the electrode 5, a conductive structure 42 connected to the fixing part 41, and a buffer structure 43. The conductive structure 42 is in contact with the heating element 2, and the buffer structure 43 is used for elastic contact with the base 6, and / or, the buffer structure 43 is used for elastic contact with the oil cup 1.
[0031] The buffer structure 43 is in elastic contact with the base 6 and / or the oil cup 1, which can be direct or indirect contact.
[0032] Specifically, the fixing part 41 has a through hole, and one end of the electrode 5 passes through the through hole to be fixedly connected to the fixing part 41. In some specific examples, the heating element 2 includes a rigid substrate and a heating coating disposed on the rigid substrate, wherein the rigid substrate is a glass substrate or a ceramic substrate, which is thin and brittle. The fixing part 41, the conductive structure 42, and the buffer structure 43 can be an integrally molded structure with good structural stability; the electrode 5 and the heating element 2 are connected by the conductive element 4, and the buffer structure 43 is provided on the conductive element 4, so that if the electronic atomizing device is accidentally dropped, the buffer structure 43 can make elastic contact with the oil cup 1 and / or the base 6, thereby preventing the heating element 2 from breaking due to excessive contact with the conductive structure 42. In this embodiment, the elastic sealing element 3 can refer to a ceramic silicone element. The outer periphery of the heating element 2 can be press-sealed by the elastic sealing element 3, thereby effectively preventing e-liquid (i.e., atomizing liquid) from seeping out from the connection between the outer periphery of the heating element 2 and the elastic sealing element 3, ensuring the leak-proof stability of the electronic atomizing device.
[0033] like Figures 2-4As shown in the embodiment, the conductive structure 42 includes a support wall 421, a contact portion 423, and a bending connecting portion 422 bendingly connected between the support wall 421 and the contact portion 423, one end of the support wall 421 bendingly connected to the fixing portion 41, and one side of the contact portion 423 in contact with the heat-generating body 2. The support wall 421 and the contact portion 423 are transitionally connected through the bending connecting portion 422, which can ensure that the support wall 421 can provide sufficient support to the contact portion 423, avoid poor contact between the heat-generating body 2 and the contact portion 423, and improve the buffering capacity of the conductive structure 42 and reduce the risk of the heat-generating body 2 being broken due to impact.
[0034] In the embodiment, as shown in the figure, Figure 5 The contact portion 423 has a bulge structure 4231 arranged towards the heat-generating body 2, which is used for contact connection with the heat-generating body 2. The bulge structure 4231 is an arc-shaped convexity integrally formed with the contact portion 423, has a certain elasticity, and can form a buffer between the heat-generating body 2 and the contact portion 423 when the heat-generating body 2 and the contact portion 423 are subjected to the inertial force of mutual approach, thereby effectively preventing the impact force from damaging the heat-generating body 2.
[0035] In the embodiment, in a natural state, the plane of the contact portion 423 is parallel to the plane of the heat-generating body 2. Since the contact portion 423 has a large contactable plane, the problems of contact failure due to too small contact surface and damage to the structure of the heat-generating body 2 due to too large contact pressure when impacted can be effectively solved. The included angle between the bending connecting portion 422 and the support wall 421 is 100°-130°, and / or the included angle between the bending connecting portion 422 and the contact portion 423 is 100°-130°. Through the design of such a bending structure, the conductive structure 42 has sufficient elastic deformation capacity and good buffering performance.
[0036] As shown in the figure, Figure 4 and 5As shown, in the embodiment, the buffer structure 43 comprises an abutting portion 431 bently connected to the support wall 421, and the abutting portion 431 abuts against the bottom side of the elastic sealing piece 3. The abutting portion 431 can be a sheet-shaped structure vertically connected to one side of the top of the support wall 421. By abutting against the elastic sealing piece 3 on the bottom side, the abutting portion 431 can effectively avoid the downward displacement of the elastic sealing piece 3 from driving the heating body 2 to impact the contact portion 423, thereby improving the assembly stability among the elastic sealing piece 3, the heating body 2 and the conductive piece 4, and improving the impact resistance of the electronic atomization device. Further, in the embodiment, a reinforcing rib 432 is arranged at the bent connection between the support wall 421 and the abutting portion 431. The reinforcing rib 432 can be a triangular supporting block connected between the support wall 421 and the abutting portion 431. The presence of the reinforcing rib 432 increases the structural strength between the support wall 421 and the abutting portion 431, and can effectively prevent the abutting portion 431 from being deformed under impact.
[0037] In the embodiment, the buffer structure 43 further comprises an extension arm 433 connected to the contact portion 423 and extending towards the base 6, and a free end 434 connected to the extension arm 433 away from the contact portion 423. The free end 434 has a buffer interval with the base 6 and the inner wall of the oil cup 1. Specifically, the free end 434 can be a hook-shaped structure. The arrangement of the extension arm 433 and the free end 434 can effectively absorb the impact force of the drop impact on the conductive structure 42, and effectively avoid the separation of the conductive structure 42 from the heating body 2 to cause poor circuit contact. The free end 434 has a certain buffer interval (buffer distance) with the base 6 and the inner wall of the oil cup 1. The buffer distance is less than the pre-pressing amount of the heating body 2 and the contact portion 423, thereby ensuring that the contact portion 423 can accommodate a certain amount of deformation during the drop of the electronic atomization device, and preventing the hard top of the conductive piece 4 from causing the heating body 2 to break.
[0038] It can be understood that, in other embodiments, the free end 434 can be directly in elastic contact with the base 6.
[0039] As shown in Figure 1 and 2 In the embodiment, the atomization assembly further comprises a liquid guide 7 abutting against one side of the heating body 2 away from the atomization cavity 11; the elastic sealing piece 3 is formed with an assembly cavity 31 adapted to the heating body 2 and the liquid guide 7, and the heating body 2 and the liquid guide 7 are both fixed in the assembly cavity 31; and the oil cup 1 has a liquid storage cavity 13 communicating with the assembly cavity 31.
[0040] Specifically, the liquid guide 7 can be mesh cotton. During the operation of the electronic atomization device, the liquid in the liquid storage cavity 13 can enter the liquid guide 7 through the assembly cavity 31 and then reach the heating body 2. The heating body 2 can heat and atomize the atomized liquid to form an aerosol. The generated aerosol can mix with the air entering from the air inlet channel and then reach the electronic atomization device along the air outlet channel 12 for the user to experience.
[0041] As shown in Figure 2 and 3 , in the present embodiment, the assembly cavity 31 is further provided with a first inner extension 34 extending towards the axis of the assembly cavity 31 at the port near one end of the liquid storage cavity 13; the atomization assembly further comprises a support block 8, the edge of one side of the support block 8 abuts against the first inner extension 34, and the edge of the other side abuts against the liquid guide 7; the support block 8 is provided with a clearance 81 communicating the liquid storage cavity 13 and the liquid guide 7. Specifically, the support block 8 can be a steel sheet, which can support the assembly cavity 31 of the elastic sealing piece 3 and improve the structural strength of the elastic sealing piece 3. The first inner extension 34 can further press the liquid guide 7 tightly above the heating body 2, so as to avoid the expansion of the liquid guide 7. The support block 8 thus arranged can extend the oil inlet path to a certain extent, which is beneficial to preheating of the tobacco tar.
[0042] As shown in Figure 2 and 3 , in the present embodiment, the assembly cavity 31 is further provided with a second inner extension 35 extending towards the axis of the assembly cavity 31 at the port near one end of the atomization cavity 11, and the edge of the side of the heating body 2 away from the liquid guide 7 abuts against the second inner extension 35. The second inner extension 35 can realize the partial clamping of the elastic sealing piece 3 from the bottom side to the heating body 2, so as to prevent the separation of the planar heating body 2 and the elastic sealing piece 3 during assembly.
[0043] In the present embodiment, as shown in Figure 1 , 4 , 6, the outer side of the elastic sealing piece 3 is provided with a sealing ring 32 abutting against the inner wall of the oil cup 1. The sealing ring 32 and the main body of the elastic sealing piece 3 can be an integral molding structure, and the sealing ring 32 can be provided with one or multiple spaced sealing rings. The sealing ring 32 can effectively prevent the tobacco tar from leaking out of the space between the elastic sealing piece 3 and the inner wall of the oil cup 1, thereby improving the leakage prevention performance of the electronic atomization device. In the present embodiment, as shown in Figure 6 , the top of the base 6 is further formed with a mounting cavity 61, and the mounting cavity 61 is provided with a liquid suction piece 9. The liquid suction piece 9 can be an oil absorption cotton. The liquid suction piece 9 arranged at the bottom side of the atomization cavity 11 can absorb the atomized liquid leaked from the atomization cavity 11 by mistake, thereby further improving the leakage prevention performance of the electronic atomization device.
[0044] The above merely describes the preferred embodiments of the present application, and is not intended to limit the present application, and any modification, equivalent replacement, and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
