Description

Technical Field

[0001] The utility model relates to the technical field of electronic cigarettes, and in particular to an atomization core connecting mechanism and an electronic cigarette. Background Art

[0002] An e-cigarette is an electronic product that mimics cigarettes, with the same appearance, smoke, taste, and feel. It uses a battery-powered atomizer to heat the oil in the tank, converting nicotine and other substances into vapor for the user to inhale. An e-cigarette consists of a mouthpiece, a reservoir, an air inlet, and an atomizer core. The atomizer core is located at the oil outlet of the reservoir, allowing the oil in the reservoir to flow into the atomizer core. The battery powers the atomizer core, which heats the oil into a mist-like vapor that is then inhaled by the user.

[0003] The installation of the atomizer core of existing electronic cigarettes is relatively cumbersome. The pins of the heating core need to be connected to the circuit board through wires through manual welding. It is difficult to ensure the welding yield rate. In addition, during the assembly process, the solder pads are prone to fall off, resulting in poor contact and affecting the normal operation of the electronic atomizer. Utility Model Content

[0042] It should also be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections, direct connections, connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0043] like Figures 1 to 4 The electronic cigarette of the present invention is shown, comprising a housing 100, a mouthpiece 200 located on the top of the housing 100, an atomizer core 300, a circuit board 400, a liquid storage cotton 500, and a battery 600. When a user holds the housing 100 and draws through the mouthpiece 200, the atomizer core 300 generates high temperatures, atomizing the liquid in the liquid storage cotton 500 for the user to inhale. The atomizer core 300 is electrically connected to the circuit board 400, which controls its operating temperature, among other things. The battery 600 is connected to the circuit board 400 to power the atomizer core 300.

[0044] like Figures 5 to 9 As shown, the atomizer core connecting mechanism 700 of the present invention is installed in the electronic cigarette.

[0045] The atomizer core connection mechanism 700 is used to connect the atomizer core 300 and the circuit board 400 , and includes a bracket 71 and a silicone seat 72 assembled on the upper end of the bracket 71 .

[0046] Specifically, the bracket 71 is provided with a receiving cavity 73 for accommodating the battery 600. An adapter plate 74 is fixed on the top of the inner side of the receiving cavity 73. The atomizing core 300 is arranged above the silicone seat 72. Figure 2 As shown, the atomizer core 300 includes a heating wire (not shown) for generating heat. A pin 31 connected to the heating wire extends from the atomizer core 300. The end of the pin 31 facing away from the atomizer core 300 passes through the silicone seat 72 and the bracket 71 and extends into the accommodating cavity 73. The pin 31 is connected to the adapter plate 74 to achieve the connection between the atomizer core 300 and the adapter plate 74. The circuit board 400 is provided on the side of the bracket 71, and the circuit board 400 and the adapter plate 74 are electrically connected.

[0047] During assembly, the circuit board 400 is screwed to the side of the bracket 71. The pins 31 are inserted through the silicone base 72 and the bracket 71, extending into the accommodating cavity 73 and soldered to the adapter plate 74. The adapter plate 74 is then connected to the circuit board 400 via wires, completing the connection between the atomizer core 300 and the circuit board 400. Traditionally, the pins 31 are directly soldered to the circuit board 400. During subsequent assembly of the battery 600, the battery 600 can easily scrape against the solder pads, resulting in poor contact between the pins 31 and the circuit board 400, which in turn affects the proper functioning of the atomizer core 300. The present invention incorporates an adapter plate 74 for intermediate connection, which avoids these issues, improves connection stability, and increases product yield.

[0048] Specifically, the silicone seat 72 is provided with a first wire hole 721 that passes vertically through, and the bracket 71 is provided with a second wire hole 711 that passes vertically through. When the silicone seat 72 is assembled to the bracket 71, as shown in FIG. Figure 8 As shown, a converging cavity 75 is formed between the silicone seat 72 and the bracket 71, and the two ends of the second wire-passing hole 711 respectively connect the converging cavity 75 and the accommodating cavity 73; during assembly, the pin 31 passes through the first wire-passing hole 721 and the second wire-passing hole 711 in sequence and extends into the accommodating cavity 73. Furthermore, the first wire-passing hole 721 and the second wire-passing hole 711 are coaxially arranged, and the pin 31 passes vertically through the first wire-passing hole 721 and the second wire-passing hole 711, preventing the pin 31 from bending and affecting the normal use of the atomizer core 300. In addition, the upper end opening of the second wire-passing hole 711 is provided with a guide surface 712, which serves as a guide; during assembly, there is a certain probability that the pin 31 will tilt and then abut against the guide surface 712. Since the guide surface 712 is a tilted structure, the guide surface 712 will guide the pin 31 into the second wire-passing hole 711.

[0049] In this embodiment, if Figure 2As shown, the structure of the dual atomizer core 300 can improve the atomization effect and optimize the user's smoking experience; therefore, the heating wire 31, the first wire hole 721 and the second wire hole 711 are each provided with two groups, and the heating wire 31, the first wire hole 721 and the second wire hole 711 are provided in a one-to-one correspondence.

[0050] Specifically, a plug-in column 722 is provided at the upper end of the silicone seat 72, and a first wire hole 721 vertically passes through the plug-in column 722; correspondingly, a vertical airway is provided in the oil storage cotton 500, and the plug-in column 722 is plugged into the airway, and the first wire hole 721 is connected to the airway, thereby realizing the connection between the silicone seat 72 and the oil storage cotton 500. Furthermore, a convex ring is provided on the outer wall of the plug-in column 722, such as Figure 4 As shown, the convex ring cooperates with the inner wall of the airway, and the connection is firm and not easy to fall off.

[0051] Specifically, sealant (not shown) is applied between the second wire hole 711 and the pin 31, and also at the connection between the pin 31 and the adapter plate 74. After the pin 31 passes through the first wire hole 721 and the second wire hole 711, sealant is injected into the second wire hole 711 to seal it and prevent condensation or e-liquid from passing through. Sealant is also injected at the connection between the pin 31 and the adapter plate 74, making the weld between the pin 31 and the adapter plate 74 more secure.

[0052] Specifically, if Figure 6 As shown, a limiting protrusion 731 is provided at the top of the accommodating cavity 73, and the limiting protrusion 731 is arranged around the second wire hole 711; correspondingly, an air-avoiding notch 741 is provided on the adapter plate 74; when the adapter plate 74 is fixed to the top of the accommodating cavity 73, the air-avoiding notch 741 fits with the limiting protrusion 731, thereby preventing the adapter plate 74 from moving in the horizontal direction and preventing it from loosening.

[0053] Specifically, if Figure 5 As shown, a barb 732 is provided at the top of the inner side of the accommodating cavity 73. During assembly, one end of the adapter plate 74 is clamped in the barb 732, thereby fixing the adapter plate 74 to the top of the inner side of the accommodating cavity 73. Alternatively, bolts, welding, or other connection methods can be used to fix the adapter plate 74 to the top of the inner side of the accommodating cavity 73 according to actual needs.

[0054] Compared with the prior art, the atomizer core connection mechanism 700 and the electronic cigarette involved in the present invention are provided with a bracket 71 and a silicone seat 72. The bracket 71 is provided with a accommodating cavity 73, and an adapter plate 74 is provided on the top of the accommodating cavity 73. During specific assembly, the circuit board 400 is assembled on the side of the bracket 71, and the atomizer core 300 is assembled on the top of the bracket 71. The atomizer core 300 extends a pin 31 for electrical connection. The pin 31 passes through the silicone seat 72 and the support and is welded to the adapter plate 74. The adapter plate 74 is then connected to the circuit board 400. The connection between the atomizer core 300 and the circuit board 400 is achieved through the adapter plate 74, which makes the connection more stable and the yield rate high. Compared with the pin 31 directly welded to the circuit board 400, the operation difficulty is low, and it is not easy to fall off during the assembly process of the electronic cigarette.

[0055] The above merely represents the preferred technical solution of the present invention. While the description is relatively specific and detailed, it should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the concept of the present invention, and the present invention is intended to encompass such modifications and variations.
