[0002] With the rapid development of the atomizer market, more and more innovative technologies are being applied to atomizer products to enhance user experience and product performance. As an electronic product that replaces traditional cigarettes, the heating structure of electronic cigarettes is a vital component. The heating structure of traditional electronic cigarettes usually includes components such as heating wires, heating cores, and heating bodies, which heat the smoke oil to generate atomized gas for users to inhale. Among them, heating control technology has always been one of the research hotspots in the field of atomizers. The heating control of traditional atomizers mainly controls the temperature of the heating element by adjusting the voltage or power. The heating element, as a heating element, plays a vital role in the heating process of the smoke oil (atomizer liquid).

[0003] Currently, most existing atomizers use laser welding to connect the heating element and the electrode, or lead the heating element out of the atomizing chamber and connect the power supply outside the atomizing chamber. However, laser welding will damage the electroplating layer of the electrode, causing safety issues such as the release of metal nickel; and leading the heating element out of the atomizing chamber requires the use of glue to seal the pin hole, which has hidden dangers in terms of environmental safety. Utility Model Content

[0004] Based on this, it is necessary to provide an atomizer heating structure and an atomizer to address the problem of inconvenient connection between the existing heating element and the electrode.

A part of the connecting part is arranged in the first step groove, and the other part is arranged in the second step groove, so that the connecting part is in conflict with the electrode.

[0009] In one embodiment, along the axial direction of the shell, the length of the connecting portion is greater than the length of the first step groove; along the thickness direction of the heating portion, the length of the connecting portion is greater than the length of the first step groove.

[0010] In one embodiment, the first half shell and the second half shell jointly clamp the connecting portion, and the connecting portion is in contact with the inner walls of the first step groove and the second step groove.

[0012] In one embodiment, a protrusion is provided on the shell, a first groove is formed on the support seat, and a second groove is formed on the heating element. Both the first groove and the second groove match the protrusion so that the protrusion can be inserted into the first groove and the second groove.

[0013] In one embodiment, the first half shell and the second half shell are detachably connected.

[0014] In one of the embodiments, a slot is provided on the first half shell, and a block is provided on the second half shell. The block cooperates with the slot to achieve the engagement of the first half shell and the second half shell.

[0032] With the rapid development of the atomizer market, more and more innovative technologies are being applied to atomizer products to improve user experience and product performance. Among them, heating control technology has always been one of the research hotspots in the field of atomizers. The heating control of traditional atomizers mainly controls the temperature of the heating element by adjusting the voltage or power. The heating element, as a heating element, plays a vital role in the heating process of the e-liquid (atomizer liquid).

[0033] Currently, most existing atomizers use laser welding to connect the heating element and the electrode, or lead the heating element out of the atomizing chamber and connect the power supply outside the atomizing chamber. However, laser welding will damage the electroplating layer of the electrode, causing safety issues such as the release of metal nickel; and leading the heating element out of the atomizing chamber requires the use of glue to seal the pin hole, which has hidden dangers in terms of environmental safety.

[0034] To this end, the present application provides an atomizer heating structure and an atomizer. The atomizer heating structure achieves a stable connection between the electrode and the heating element by changing the connection mode between the heating element and the electrode. The atomizer heating structure and the structure of the atomizer in the present application are described below. This embodiment is only used as an example and does not limit the technical scope of the present application.

[0035] See also Figure 1 and Figure 2 , Figure 1 The schematic diagram of the structure of the atomizer in one embodiment of the present application is shown. The atomizer provided in one embodiment of the present application includes an atomizer heating structure and an oil cup shell 10. A base 20 is provided on the atomizer heating structure, and the oil cup shell 10 is detachably connected to the base 20. A connecting block 210 is fixed on the base 20, and a connecting groove 110 is provided on the oil cup shell 10. The connecting block 210 is inserted into the connecting groove 110 to realize the clamping connection between the base 20 and the oil cup shell 10.

[0036] Furthermore, the side of the connecting block 210 facing the oil cup shell 10 is tilted downward relative to the horizontal plane, which can facilitate the connecting block 210 to be inserted into the connecting groove 110 during installation, so as to achieve a better connection effect and facilitate installation and removal. It is not difficult to understand that in other embodiments, the oil cup shell 10 and the base 20 can also be connected by other methods such as magnetic attraction, which is not limited here.

[0037] See also Figure 1 and Figure 2 The oil cup shell 10 is provided with a receiving cavity 120, and the atomizer heating structure is arranged in the receiving cavity 120. The atomizer heating structure includes a shell 30 and an electrode 40. The base 20 is provided with a mounting hole 220. There are two mounting holes 220. The mounting holes 220 are arranged along the axial direction of the shell 30 ( Figure 2 There are two electrodes 40, each of which is inserted into the mounting hole 220.

[0038] The base 20 is also provided with a receiving groove 2230, which is connected to the mounting hole 220. The receiving groove 2230 is specifically a waist-shaped groove in this embodiment. A limiting piece 410 is fixed to one end of the electrode 40 away from the oil cup shell 10. The limiting piece 410 is specifically a waist-shaped structure in this embodiment. The receiving groove 2230 matches the limiting piece 410, and the receiving groove 2230 is used for the limiting piece 410 to be inserted. The electrode 40 can be limited by providing the limiting piece 410, and the flatness of the outer surface of the base 20 can be ensured by providing the receiving groove 2230, so as to achieve a better installation effect and facilitate use.

[0039] See also Figure 3 The housing 30 includes a first half shell 320 and a second half shell 330. The second half shell 330 is fixedly connected to the base 20. Specifically, the second half shell 330 and the base 20 are integrally formed. The first half shell 320 and the second half shell 330 are detachably connected. A slot 3210 is provided on the first half shell 320. A block 3310 is fixed on the second half shell 330. The block 3310 cooperates with the slot 3210 to achieve the engagement of the first half shell 320 and the second half shell 330. In this embodiment, the block 3310 is arranged in the length direction ( Figure 3 There are at least two card blocks 3310, and two adjacent card blocks 3310 are arranged at intervals. The number of card slots 3210 corresponds to the card blocks 3310, so as to achieve a better snap connection effect. In other embodiments, the number of card blocks 3310 and card slots 3210 can also be set according to the size of the atomizer heating structure, which is not limited here.

[0040] It is not difficult to understand that a slope 3311 is provided on the side of the block 3310 close to the first half shell 320, and the slope 3311 is inclined relative to the horizontal plane toward the side close to the first half shell 320, so as to facilitate the block 3310 to be inserted into the slot 3210 on the first half shell 320, thereby facilitating the connection between the first half shell 320 and the second half shell 330, and the connection effect is good.

[0041] In some embodiments, the first half shell 320 and the second half shell 330 may also be connected by magnetic connection, plug-in connection or other connection methods, which are not limited here.

[0042] See also Figure 3A mounting cavity 310 is provided between the first half shell 320 and the second half shell 330, a support seat 350 is provided in the mounting cavity 310, and the support seat 350 is specifically made of silicone material in this embodiment, a convex block 3320 is fixed on the second half shell 330, a first groove 3510 is provided on the support seat 350, the convex block 3320 matches the first groove 3510, and the convex block 3320 is inserted into the first groove 3510. By providing the convex block 3320, the support seat 350 can be positioned, and the connection between the support seat 350 and the second half shell 330 is realized.

[0043] See also Figure 3-Figure 5 Further, the heating structure of the atomizer also includes a heating element 50, which is specifically in the form of a sheet in this embodiment. The heating element 50 includes a connecting portion 510 and a heating portion 520, and the heating portion 520 is in the form of a mesh and is integrally formed with the connecting portion 510. In this embodiment, two connecting portions 510 are provided, and each connecting portion 510 corresponds to the position of each electrode 40. A second groove 5210 is provided on the heating portion 520 of the heating element 50, and the second groove 5210 is connected to the first groove 3510, and the second groove 5210 cooperates with the convex block 3320, and the convex block 3320 is inserted in the second groove 5210, so that the positioning of the heating element 50 can be achieved.

[0044] By providing the protrusion 3320, the protrusion 3320 passes through the first groove 3510 on the support base 350 and the second groove 5210 on the heating element 50, so as to facilitate the installation and positioning of the support base 350 and the heating element 50. When the heating element 50 needs to be replaced, it is also convenient to remove the heating element 50 for replacement and cleaning, and the operation is convenient.

[0045] See also Figure 3-Figure 5 In this embodiment, the connection portion 510 is formed by bending the heating element 50 twice. A first step groove 360 ​​is provided on the side of the first half shell 320 facing the second half shell 330, and a second step groove 370 is provided on the side of the second half shell 330 facing the base 20. A part of the connection portion 510 is arranged in the first step groove 360, and another part is arranged in the second step groove 370. The second step groove 370 is connected to the mounting hole 220, so that the connection portion 510 is in contact with the electrode 40. Along the axial direction of the housing 30 ( Figure 5 Y direction), the length of the connecting portion 510 is greater than the length of the first step groove 360; along the thickness direction of the heating portion 520 ( Figure 5 The length of the connecting portion 510 is greater than the length of the first step groove 360. The first half shell 320 and the second half shell 330 jointly clamp the connecting portion 510, and the connecting portion 510 is in contact with the inner walls of the first step groove 360 ​​and the second step groove 370. In this way, the positioning of the heating element 50 is achieved, and the stable connection between the heating element 50 and the electrode 40 is achieved.

[0046] Specifically, during installation, the heating element 50 is first installed on the support seat 350, and then the first half shell 320 is installed on the second half shell 330. The first half shell 320 contacts the heating element 50, and the connecting portion 510 of the heating element 50 can be bent. After installing the first half shell 320, the electrode 40 is inserted into the mounting hole 310, and the electrode 40 contacts the connecting portion 510, and the connecting portion 510 is pushed into the second step groove 370. In this way, the positioning of the heating element 50 can be achieved, the displacement of the heating element 50 in the three directions of X, Y, and Z can be limited, and the contact between the electrode 40 and the heating element 50 can also be achieved.

[0047] It can be seen that the present application changes the connection method between the heating element 50 and the electrode 40, changes the traditional welding and lead-out connection method, and uses the base 20 and the support seat 350 to press the heating element 50, thereby realizing the connection between the electrode 40 and the heating element 50, which is conducive to automated production, and the connection method is convenient and reliable, perfectly improves the heavy metal nickel release and environmental safety problems caused by traditional welding methods, and also helps to improve production capacity.
