In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0039] See also Figure 1-13 The embodiment of the utility model provides a buffer structure 10 for electrically connecting to a heating element. The buffer structure 10 comprises an electrode 1, a reset member 2 and a fixing frame 3. The electrode 1 can move axially relative to the fixing frame 3 and has a free end 11 that is in electrical contact with the heating element. The reset member 2 is arranged on the fixing frame 3. The reset member 2 is located on the outside of the electrode 1 and away from the free end 11. The reset member 2 is used to provide an elastic force that makes the free end 11 contact with the heating element, so that the electrode 1 moves axially relative to the fixing frame 3.

[0040] In the embodiment of the utility model, the free end 11 of the electrode 1 is used to be electrically connected to the heating element, so that the high heat area of ​​the electrode 1 is mainly concentrated at the free end 11 of the electrode 1. The reset member 2 is used to provide elastic force to make the free end 11 and the heating element contact and connect, so that the electrode 1 can move relative to the fixed frame 3 along the axial direction, and when the electrode 1 and the heating element are connected, there is a buffering effect between the electrode 1 and the heating element; because the reset member 2 is located outside the electrode 1 and away from the free end 11 of the electrode 1, on the one hand, the electrode 1 can be an independent structure, and there is no need to have a spring built into the electrode 1, that is, the electrode 1 and the reset member do not need to use precision devices like pogo pins, so that the current carrying capacity and heat deformation resistance of the electrode 1 can be increased, and the size of the reset member 2 can be larger, improving its structural strength and heat deformation resistance; on the other hand, the high heat area of ​​the electrode 1 is mainly concentrated at the free end 11, and the reset member 2 is away from the free end 11 of the electrode 1, so that the heat conduction between the electrode 1 and the reset member 2 can be reduced, and then the service life of the reset member 2 can be extended, so that the buffer structure 10 can be suitable for high temperature scenes.

[0041] It should be noted that the axial direction is parallel to Figure 2 and Figure 8 The direction of the Z axis is shown in .

[0042] Furthermore, the reset member 2 may be a structural member with a reset function, and may be a spring, a metal spring, a silicone member, or other forms of elastic structural members.

[0043] Furthermore, the reset member 2 is disposed around the outer circumference of the portion of the electrode 1 away from the free end 11 , and one end of the reset member 2 is connected to the fixing frame 3 and the other end is directly or indirectly connected to the electrode 1 .

[0044] For some specific embodiments, see Figure 1-6 The fixing frame 3 includes a first bracket 31 and a second bracket 32 ​​fixed to one side of the first bracket 31, the first bracket 31 is provided with a first through hole 311; the electrode 1 is passed through the first through hole 311, and the electrode 1 is also provided with a first limiting portion 12, the first limiting portion 12 is movably located between the first bracket 31 and the second bracket 32, the reset member 2 is elastically supported on the first limiting portion 12 and the second bracket 32 ​​respectively, and the free end 11 protrudes from the other side of the first bracket 31 away from the second bracket 32.

[0045] Specifically, taking the reset member 2 as a spring as an example, the spring can be sleeved on the outer peripheral side of the electrode 1 and abut against the first limit portion 12 and the second bracket 32, and the first limit portion 12 is movably located between the first bracket 31 and the second bracket 32, so the first limit portion 12 can be used to compress the spring. Within the expansion and contraction range of the spring, the spring drives the first limit portion 12 to move in the first bracket 31 and the second bracket 32, so that the spring drives the electrode 1 to move relative to the first bracket 31 and the second bracket 32; and the free end 11 of the electrode 1 protrudes from the other side of the first bracket 31 away from the second bracket 32, so the spring can achieve a buffering effect when the free end 11 of the electrode 1 is in contact with the heating element.

[0046] For further information, see Figure 1-6 The second bracket 32 ​​is further provided with a second through hole 321 , the second through hole 321 is coaxial with the first through hole 311 , and the other end of the electrode 1 away from the free end 11 is passed through the second through hole 321 .

[0047] Specifically, the two ends of the electrode 1 are respectively inserted into the first through hole 311 and the second through hole 321, so that the reliability of the axial movement of the electrode 1 in the first through hole 311 and the second through hole 321 can be ensured, and the jamming problem caused by the offset during the movement can be avoided. Among them, the axial projection surface of the first limit portion 12 is larger than the first through hole 311 and the second through hole 321, so that the first limit portion 12 can be movably located between the first bracket 31 and the second bracket 32, and the electrode 1 can be prevented from moving away from the first through hole 311 to the first bracket 31 or from the second through hole 321 to the second bracket 32, so that the electrode 1 is movably connected to the first bracket 31 and the second bracket 32 ​​within the expansion and contraction range of the spring.

[0048] For further information, see Figure 1-6 The buffer structure 10 further includes a third bracket 33 , in which a receiving cavity is formed. The first bracket 31 and the second bracket 32 ​​are at least partially located in the receiving cavity and are fixedly connected to the third bracket 33 .

[0049] In some specific embodiments, the second bracket 32 ​​and the third bracket 33 can be connected in a detachable manner by snap-fitting or threaded connection, and a receiving cavity is formed in the third bracket 33, and a protrusion protrudes from the receiving cavity, and a protruding column protrudes from the second bracket 32 ​​into the receiving cavity, and the first bracket 31 is located in the receiving cavity and is snap-fitted between the protrusion and the protruding column, so that the first bracket 31 can be conveniently assembled between the second bracket 32 ​​and the third bracket 33.

[0050] Furthermore, the material of the first bracket 31 can be PEEK (Polyetheretherketone), ceramic or other heat-insulating materials. The free end 11 of the electrode 1 protrudes from the side of the first bracket 31 away from the second bracket 32, that is, the first bracket 31 is close to the free end 11 of the electrode 1, and the free end 11 is used to contact and connect with the heating element. Therefore, setting the first bracket 31 to a low thermal conductivity, temperature-resistant material can reduce the heat transferred from the side of the first bracket 31 away from the second bracket 32 ​​to the other side of the first bracket 31, and the spring is located between the first bracket 31 and the second bracket 32, so the heat transfer to the spring can be reduced, thereby extending the service life of the spring and improving the overall temperature resistance.

[0051] See also Figure 1-6 Still taking the reset member 2 as a spring as an example, the specific assembly process of the buffer structure 10 can be: first, the spring is sleeved on the outer peripheral side of the electrode 1, and is located on the side of the first limiting portion 12 of the electrode 1 away from the free end 11; then, the other end of the free end 11 of the electrode 1 is passed through the second through hole 321 of the second bracket 32, and the spring is abutted against the second bracket 32 ​​and the first limiting portion 12 of the electrode 1; then, the first bracket 31 and the electrode 1 are connected, and the free end 11 of the electrode 1 is passed through the first through hole 311 of the thermal insulation plate; finally, this whole is snap-connected to the third bracket 33.

[0052] For further information, see Figure 1-6 The buffer structure 10 includes at least two electrodes 1, and each electrode 1 corresponds to a reset member 2. Therefore, the electrodes 1 do not interfere with each other during operation, which can improve the contact effect with the heating element.

[0053] For further information, see Figure 7-13 In some specific embodiments, the fixing frame 3 includes a first bracket 31 and a second bracket 32, and the first bracket 31 is movably connected to one side of the second bracket 32; the electrode 1 is passed through the first bracket 31, and the free end 11 protrudes from the side of the first bracket 31 away from the second bracket 32; the reset member 2 is elastically supported on the first bracket 31 and the second bracket 32 ​​respectively.

[0054] Specifically, still taking the reset member 2 as a spring as an example, the second bracket 32 ​​is provided with an annular groove, the spring is assembled in the annular groove and abuts between the first bracket 31 and the second bracket 32, and the first bracket 31 is movably connected to one side of the second bracket 32, therefore, the first bracket 31 can be used to compress the spring, and the spring can be extended and retracted between the first bracket 31 and the second bracket 32 ​​to provide the first bracket 31 with an elastic force to drive the electrode 1 to move axially away from the second bracket 32. Moreover, the free end of the electrode 1 protrudes from the side of the first bracket 31 away from the second bracket 32, therefore, the spring can achieve a buffering effect when the free end 11 of the electrode 1 is in contact with the heating element. In addition, the spring is not directly abutted against the electrode 1, therefore, the heat transfer path from the electrode 1 to the spring can be extended, thereby better reducing the conduction of heat.

[0055] For further information, see Figure 7-13 The second bracket 32 ​​is provided with a third through hole 322; a limiting member is provided on the side of the first bracket 31 facing the second bracket 32, the limiting member is passed through the third through hole 322, and a limiting edge 312 is provided on the end of the limiting member away from the first bracket 31, and the limiting edge 312 is used to abut against the other side of the second bracket 32 ​​away from the first bracket 31.

[0056] Specifically, the limiting member is passed through the third through hole 322. When the spring drives the first bracket 31 to move relative to the second bracket 32, the limiting member moves synchronously in the third through hole 322. The limiting edge 312 of the limiting member is used to abut against the other side of the second bracket 32 ​​away from the first bracket 31. Therefore, the first bracket 31 can be movably connected to one side of the second bracket 32, and the first bracket 31 can be prevented from being separated from the second bracket 32 ​​through the third through hole 322.

[0057] For further information, see Figure 7-13 The limiting member includes a limiting column 313 integrally formed on the first bracket 31 and a fastener 314 detachably connected to the limiting column 313 . The limiting column 313 is penetrated by the third through hole 322 , and the limiting edge 312 is formed on the fastener 314 .

[0058] Specifically, during assembly, the limiting column 313 of the first bracket 31 can be firstly inserted into the third through hole 322, and then the fastener 314 can be assembled and connected to the limiting column 313 from the side of the second bracket 32 ​​away from the first bracket 31, so that the limiting edge 312 abuts against the side of the second bracket 32 ​​away from the first bracket 31. Such a configuration can simplify the assembly of the first bracket 31 and the second bracket 32.

[0059] For some specific embodiments, see Figure 7-13The limiting column 313 is provided with a threaded hole opening toward the second bracket 32, the fastener 314 is a screw, the screw and the threaded hole are threadedly connected, the limiting edge 312 is a nut of the screw, the nut protrudes from the third through hole 322 and is located on the side of the second bracket 32 ​​away from the first bracket 31, so that the first bracket 31 is movably connected to the second bracket 32 ​​and does not move away from the second bracket 32 ​​through the third through hole 322. In addition, the installation position of the first bracket 31 can be fine-tuned by adjusting the tightness of the screw.

[0060] In some specific embodiments, the fastener 314 is disposed between the hole wall of the third through hole 322 and the limiting column 313. The fastener 314 is provided with a through hole, and an internal thread is provided in the through hole, while the limiting column 313 is provided with an external thread, and the two are threadedly connected, so that the fastener 314 and the limiting column 313 can be threadedly connected. The limiting edge 312 is a protruding structure protruding from the peripheral side of the fastener 314 body, and the protruding structure abuts against the side of the second bracket 32 ​​away from the first bracket 31. Such a configuration can also simplify the assembly of the first bracket 31 and the second bracket 32.

[0061] See also Figure 7-13 Still taking the reset member 2 as a spring as an example, the specific assembly process of the buffer structure 10 can be: first assemble the electrode 1 on the first bracket 31, and at the same time assemble the spring in the annular groove of the second bracket 32, and then align the first bracket 31 equipped with the electrode 1 with the second bracket 32, wherein the limiting column 313 of the first bracket 31 is aligned with the third through hole 322, and finally, from the side of the third bracket 33 away from the spring, the fastener 314 and the thread of the limiting column 313 are connected.

[0062] For further information, see Figure 7-13 The first bracket 31 is provided with a second-step through hole 315 which penetrates along the axial direction, and the second-step through hole 315 has a step surface; the electrode 1 is passed through the second-step through hole 315, and the electrode 1 is also provided with a second limiting portion 13, and the second limiting portion 13 abuts against the step surface on one side facing the second bracket 32.

[0063] Specifically, the second limiting portion 13 of the electrode 1 abuts against the step surface. Therefore, when the heating element presses the free end 11 of the electrode 1, the second limiting portion 13 can press the step surface, so that the electrode 1 can drive the first bracket 31 to move axially, so that the first bracket 31 can compress the spring, and when the spring rebounds and drives the first bracket 31 to move back, the step surface of the first bracket 31 can drive the electrode 1 to move back, thereby achieving a buffering effect.

[0064] For further information, see Figure 7-13An electrode 1 lead through hole 323 is provided at a position of the second bracket 32 ​​corresponding to the electrode 1 , so that when the buffer structure 10 and the battery rod 40 are connected, the lead of the electrode 1 can be connected to the battery cell of the battery rod 40 through the electrode 1 lead through hole 323 .

[0065] For further information, see Figure 1-13 The fixing frame 3 can be made of low thermal conductivity and temperature resistant materials to reduce the heat conduction to the spring. For example, it can be PEEK, ceramics, etc.

[0066] Furthermore, the electrode 1 can be made of common conductive materials, for example, copper, iron, etc. In addition, the surface of the electrode 1 can be gold-plated to improve the conductivity. In addition, the electrode 1 can select the current required to be carried according to the actual application, and can adopt a solid structure or a structure with internal openings. The internal openings can reduce the heat conduction area.

[0067] Furthermore, the spring is made of ordinary spring wire or high temperature resistant spring material according to actual application.

[0068] Furthermore, the buffer structure 10 further includes a heat insulating member 4, which is wrapped around the outer peripheral side of the fixing frame 3 for heat insulation. Exemplarily, the heat insulating member 4 may be aerogel.

[0069] For further information, see Figure 6 and Fig.13 A battery rod assembly includes a battery rod 40 and a buffer structure 10, wherein the battery rod 40 includes a shell 30 and a battery cell arranged in the shell 30, wherein the buffer structure 10 is arranged in the shell 30, and the electrode 1 of the buffer structure 10 is electrically connected to the battery cell, and the buffer structure 10 and the shell 30 enclose an installation cavity for accommodating a heating element on one side of the free end 11 of the electrode 1.

[0070] In some specific embodiments, the third bracket 33 and the shell 30 also form an installation cavity connected to the accommodating cavity, wherein the accommodating cavity is used to assemble the first bracket 31, the second bracket 32 ​​and the electrode 1, and the free end 11 of the electrode 1 faces the installation cavity. Therefore, when the heating element is assembled in the installation cavity, the heating element can be in contact and connected with the free end 11 of the electrode 1, and the buffering effect of the connection between the two can be achieved through the buffer structure 10.

[0071] In some specific embodiments, a mounting cavity is formed on one side of the second bracket 32 ​​where the free end 11 of the electrode 1 is provided and the shell 30. Therefore, when the heating element is assembled in the mounting cavity, the heating element can be in contact and connected with the free end 11 of the electrode 1, and a buffering effect of the connection between the two can be achieved through the buffer structure 10.

[0072] For further information, see Figure 6 and Fig.13An electronic atomization device includes an atomizer 20 and a battery rod assembly. The atomizer 20 is placed in a mounting cavity. A heating element is provided at the bottom of the atomizer 20 facing the mounting cavity. The heating element is in electrical contact with the free end 11 of the electrode 1. By providing a buffer structure 10, when the battery rod assembly and the atomizer 20 are connected, an elastic connection can be achieved when the heating element and the free end 11 of the electrode 1 are in contact, so that the connection between the battery rod assembly and the atomizer 20 has a buffering effect.

[0073] In some specific embodiments, the atomizer 20 includes a heating cup, wherein the heating cup is a cylindrical structure with an open top and a closed bottom, the heating element is formed at the bottom of the heating cup, and the bottom wall of the heating cup has an electrical contact electrically connected to the heating element, and the electrical contact is used to electrically contact the free end of the electrode 1.

[0074] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0075] The above is a description of the technical solution provided by the utility model.
