Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic atomization, in particular to an electronic atomizer. BACKGROUND

[0002] In the related art, the heating body of the atomizer is electrically connected to the electrode through a pin. In a pin straight insertion structure, the pin of the heating wire passes through the electrode silica gel, and then the electrode is inserted into the silica gel hole. Since there is a gap between the electrode and the pin, the condensate is easy to flow to the battery or the circuit board through the lead. When the pin of the heating wire is a bent structure, the pin passes through the electrode silica gel and is bent to be inserted into the silica gel hole. When the electrode is inserted into the silica gel hole, the lead will be pushed forward to pull the heating wire, which finally causes structural damage to the heating wire. In addition, when the pin is bent, the bottom of the air tube and the lead are easy to come together and cause short circuit. CONTENT OF THE UTILITY MODEL

[0038] Referring to Figures 1 to 3 , wherein, Figure 1 A cross-sectional structure schematic diagram of an electronic atomizer of an embodiment is shown; Figure 2 A partial enlarged structure schematic diagram of part A in Figure 1 A partial enlarged structure schematic diagram of part A in Figure 3 An exploded structure schematic diagram of an electronic atomizer of an embodiment is shown.

[0039] As Figures 1 to 3As shown, an aspect of the present application discloses an electronic atomizer, comprising a support frame 100, an atomization assembly and an electrode 310.

[0040] Specifically, the support frame 100 is a hollow structure, and a partition wall 110 is arranged in the support frame 100. The partition wall 110 divides the support frame 100 into a first cavity 121 and a second cavity 122 along a first direction. The partition wall 110 has a communication port 111 communicating the first cavity 121 and the second cavity 122. The partition wall 110 is provided with electrode holes 112 arranged at intervals on a side facing the second cavity 122. The partition wall 110 is provided with a limiting portion 114 between the electrode holes 112 and the communication port 111. The atomization assembly is arranged in the first cavity 121 and comprises an atomization core and a lead wire 210 penetrating the communication port 111 to the second cavity 122. The lead wire 210 is connected with the atomization core. The lead wire 210 has an anti-pulling portion 211 and a conductive portion 212 connected to the anti-pulling portion 211. The anti-pulling portion 211 cooperates with the limiting portion 114, and the conductive portion 212 is at least partially located in the electrode hole 112. The electrode 310 penetrates the electrode hole 112 and is electrically connected with the conductive portion 212.

[0041] The atomization assembly comprises a heating body 230. One end of the lead wire 210 is electrically connected with the heating body 230, and the other end extends from the communication port 111 to the electrode hole 112. The end of the lead wire 210 away from the heating body 230 is the conductive portion 212, which is at least partially arranged in the electrode hole 112 to be electrically connected with the electrode 310 inserted into the electrode hole 112. The anti-pulling portion 211 is located between the conductive portion 212 and the heating body 230. During the process of inserting the electrode 310 into the electrode hole 112, the conductive portion 212 may move along with the electrode 310 towards the insertion direction of the electrode 310 due to the extrusion and friction of the electrode 310, thereby moving the anti-pulling portion 211.

[0042] In the present application, the lead wire 210 has the anti-pulling portion 211 and the conductive portion 212. The anti-pulling portion 211 is connected with the conductive portion 212, and the conductive portion 212 is arranged in the electrode hole 112 to be electrically connected with the electrode 310. During the process of inserting the electrode 310 into the electrode hole 112, the anti-pulling portion 211 can provide a buffer for the atomization assembly, and can reduce the situation that the conductive portion 212 is moved to cause the atomization core of the atomization assembly to be pulled when the electrode 310 is inserted into the electrode hole 112, thereby effectively protecting the atomization assembly. Meanwhile, the limiting portion 114 is connected with the anti-pulling portion 211, which can effectively limit the movement of the conductive portion 212 of the lead wire 210, thereby reducing the situation that the atomization core of the atomization assembly is pulled when the electrode 310 is inserted into the electrode hole 112, and is conducive to further protecting the atomization assembly.

[0043] It should be pointed out that the first direction refers to Figure 1The support frame 100 is divided into a first cavity 121 and a second cavity 122 by the partition wall 110 in the X direction.

[0044] In some embodiments of the present application, the tensile resistance portion 211 is formed by bending the lead wire 210. In this way, the structure and processing of the lead wire 210 can be simplified, thereby reducing the manufacturing cost. Meanwhile, the tensile resistance portion 211 is formed by bending the lead wire 210, that is, the tensile resistance portion 211 and the conductive portion 212 are in an integrated structure. In this way, the tensile resistance portion 211 is not easy to be pulled off or damaged when being pulled, which helps to protect the heating body 230 from being damaged.

[0045] It is to be understood that the overall shape of the tensile resistance portion 211 can be a U-shaped, a wavy shape, an arc shape, a rectangular shape or other shapes. The function of the tensile resistance portion 211 is to provide a buffer for the heating body 230 when the electrode 310 is inserted into the electrode hole 112, so as to prevent the heating body 230 from being damaged by being pulled.

[0046] In a possible implementation, the tensile resistance portion 211 is formed by bending the lead wire 210. During manufacturing, the lead wire 210 is combed into a straight line and bent by 90 degrees. A jig is used to press the bent part, and the lead wire 210 is further bent into a U-shaped by the jig. Meanwhile, the end of the lead wire 210 away from the heating body 230 is bent into the electrode hole 112. When the electrode 310 is inserted into the electrode hole 112, the electrode 310 will continue to push the lead wire 210 in the direction of insertion of the electrode 310. The U-shaped tensile resistance portion 211 will be partially straightened in this process, but the heating body 230 connected to the other end of the tensile resistance portion 211 will not be pulled. In this way, the situation that the heating body 230 is pulled can be reduced.

[0047] Of course, the tensile resistance portion 211 can also be realized by automatic equipment or other processing methods or processes to improve production efficiency.

[0048] In some embodiments of the present application, referring to Figure 1 and Figure 2 , the lead wire 210 includes a first segment and a second segment connected to each other. The first segment is located in the air tube 220 and extends in the axial direction and is connected to the atomizing core. The second segment is located in the second cavity and extends at least partially in a direction intersecting the axial direction. The flange 113 is located between the inner wall of the air tube 220 and the first segment. The tensile resistance portion 211 and the conductive portion 212 are formed in the second segment.

[0049] In some embodiments of the present application, referring to Figures 1 to 7The limiting portion 114 is a groove formed on the partition wall 110, and the anti-pulling portion 211 is at least partially arranged in the groove. The anti-pulling portion 211 is arranged in the groove, and the anti-pulling portion 211 and the conductive portion 212 are arranged in a bent manner, so that the groove can provide a certain blocking effect for the anti-pulling portion 211, thereby playing a limiting role on the anti-pulling portion 211, which helps to shorten the moving stroke of the conductive portion 212, thereby effectively protecting the heating body 230 from being pulled.

[0050] In some embodiments of the present application, the limiting portion 114 is a protrusion protruding from the surface of the partition wall 110, and the anti-pulling portion 211 is wrapped around or clamped on the protrusion. In this way, the protrusion can provide a certain supporting effect for the anti-pulling portion 211, which helps to shorten the moving stroke of the conductive portion 212, thereby effectively protecting the heating body 230 from being pulled.

[0051] In some embodiments of the present application, the first cavity 121 is a liquid storage cavity for storing atomized liquid. The liquid storage cavity is provided with a liquid outlet channel, and the atomized liquid in the liquid storage cavity flows from the liquid outlet channel to the heating body 230 to generate smoke.

[0052] In some embodiments of the present application, the atomization assembly includes a ventilation pipe 220 arranged in the first cavity 121, the ventilation pipe 220 is connected with the communication port, and the ventilation pipe 220 and the inner wall of the first cavity 121 define a liquid storage cavity; the atomization core is arranged in the ventilation pipe 220 and is in liquid communication with the liquid storage cavity, as shown in Figure 1 and Figure 2 .

[0053] In some embodiments of the present application, referring to Figure 4 , Figure 4 shows a cross-sectional structure schematic diagram of an electronic atomizer. As shown in Figure 4 , the atomization assembly includes a ventilation pipe 220 and an atomization core arranged in the ventilation pipe 220, and the lead wire 210 is electrically connected to the atomization core away from the conductive portion 212. Specifically, one end of the ventilation pipe 220 is connected with the partition wall 110, and the other end is at least partially arranged in the first cavity 121. The ventilation pipe 220 has a liquid inlet hole 221, which is in communication with the first cavity 121, and the atomized liquid in the first cavity 121 can flow to the atomization core through the liquid inlet hole 221, and then be heated and atomized by the atomization core.

[0054] In a possible implementation, the atomization core includes a heating body 230 and a liquid guiding component 240, and the liquid guiding component 240 has a liquid absorbing surface and an atomization surface. The heating body 230 abuts against the atomization surface, and the liquid absorbing surface is opposite to the liquid inlet hole 221. The atomized liquid in the first cavity 121 can flow to the liquid absorbing surface through the liquid inlet hole 221, and then be guided to the atomization surface through the inside of the liquid guiding component 240, and finally be heated and atomized by the heating body 230.

[0055] In practical applications, the liquid guiding member 240 can be oil guiding cotton. Of course, in some other embodiments, the liquid guiding member 240 can be porous ceramic or other porous medium for delivering the atomized liquid to the heating body 230.

[0056] In some embodiments of the present application, referring to Figure 1 and Figure 2 , the flange 113 extending radially inward along the communication port 111 is arranged at the end of the communication port 111 away from the first cavity 121, and one end of the vent tube 220 abuts against the side of the flange 113 facing the first cavity 121. That is, the flange 113 is arranged protruding from the inner wall of the communication port 111, and the diameter of the inscribed circle of the flange 113 is smaller than the diameter of the circumscribed circle of the cross section of the vent tube 220. In this way, the vent tube 220 can abut against the side of the flange 113 close to the first cavity 121, thereby achieving support for the vent tube 220.

[0057] In some embodiments of the present application, please continue to refer to Figure 1 and Figure 2 , the flange 113 is arranged protruding radially along the communication port 111 from the inner peripheral wall of the vent tube 220, and the end of the flange 113 is located radially between the lead wire 210 and the inner wall of the vent tube 220, so as to form an insulating gap between the lead wire 210 and the inner wall of the vent tube 220. Specifically, the diameter of the inscribed circle of the flange 113 is smaller than the inner diameter of the vent tube 220, so that there is a certain gap between the free end of the flange 113 and the inner wall of the vent tube 220. In this way, during the process of inserting the electrode 310 into the electrode hole 112, when the conductive part 212 connected with the lead wire 210 is pushed forward by the electrode 310 and the lead wire 210 between the tensile part 211 and the heating body 230 is also pulled, since there is a certain gap between the free end of the flange 113 and the inner wall of the vent tube 220, the lead wire 210 at most abuts against the flange 113 and does not abut against the inner wall of the vent tube 220, thereby forming an insulating gap between the lead wire 210 and the inner wall of the vent tube 220, effectively reducing the short circuit caused by the abutment contact between the lead wire 210 and the inner wall of the vent tube 220.

[0058] It should be pointed out that the radial direction of the communication port 111 refers to the Y direction in Figure 1 or Figure 2 .

[0059] In some embodiments of the present application, referring to Figure 6 and Figure 7The step structure 130 is arranged on one side of the second cavity 122 close to the communication port 111, and the number of the lead wires 210 is two. The two lead wires 210 are arranged at intervals, and the step structure 130 protrudes between the two lead wires 210. That is, the two lead wires 210 are separated by the step structure 130. In this way, the contact between the two lead wires 210 can be reduced, and the problem of short circuit can be reduced.

[0060] In the embodiment, the electronic atomizer further comprises a circuit board, which is electrically connected to the conductive part 212 of the atomization assembly through the electrode 310 to control the working of the heating body 230.

[0061] In some embodiments of the present application, referring to Figure 1 and Figure 2 The electronic atomizer further comprises a sealing member 330, which is arranged in the second cavity 122. The sealing member 330 is provided with a relief hole 331 through which the electrode 310 passes, and the relief hole 331 is in interference fit with the electrode 310. The sealing member 330 is sealingly connected to the cavity wall of the second cavity 122. In this way, the damage of the circuit board caused by the atomized liquid flowing to the circuit board can be effectively reduced. Meanwhile, the end of the lead wire 210 is the conductive part 212, which is arranged in the electrode hole 112 without penetrating through the relief hole 331 of the sealing member 330, so that the atomized liquid cannot flow to the circuit board along the lead wire 210, and the circuit board can be further protected.

[0062] In a possible implementation, the sealing member 330 is made of silica gel. Of course, in some other implementations, the sealing member 330 can also be made of rubber, which is not limited herein.

[0063] In some embodiments of the present application, referring to Figure 1 and Figure 2 The electronic atomizer further comprises an oil absorption cotton 340, which is arranged on one side of the sealing member 330 close to the atomization core (i.e., the oil absorption cotton 340 is arranged on one side of the sealing member 330 close to the lead wire 210) to absorb the leaked atomized liquid.

[0064] In some embodiments of the present application, the electronic atomizer further comprises a shell 400, which is a hollow structure, and the support frame 100 is arranged inside the shell 400.

[0065] The embodiments of the present application are described in detail above in combination with the drawings, but the present application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the purpose of the present application. In addition, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
