Description

A contact charging electrode structure for electronic cigarettes

Technical field

The present invention relates to the technical field of electronic cigarette chargers, and in particular to a contact charging electrode structure of an electronic cigarette.

Background technique

With the development of the e-cigarette industry, e-cigarettes are used by more and more people. The e-cigarette charger used with e-cigarettes is also a necessary part of e-cigarette users. However, current electronic cigarette chargers widely use welding in the design of the electrode structure between the charging PCB board and the electronic cigarette electrode contact head.

For welding products, whether it is manual welding or machine welding, most of the soft wires or hard wires used are soft wires or hard wires. However, the real welding area is limited and is only the small area covered by the solder. During the long-term use of the product , as the electronic cigarette rotates during charging and insertion, it gives the electronic cigarette electrode contact head a driven force. Generally speaking, the welding joint between the charging PCB board and the electronic cigarette electrode contact head is prone to aging, poor contact or even detachment. As a result, the product is directly discarded or returned for repair, and the quality of the product decreases. The present invention proposes a new electrode structure to address the shortcomings of the welding type. Because the conductive area of the contact type is much higher than that of the welding type, as long as the positive and negative springs are ensured to be in multi-directional contact with the electronic cigarette electrode contact head and are firm enough , the reliability and durability of its products will be much higher than those of welded products, and the product defect rate can also be greatly reduced. On this basis, designing a new structure that is easy to assemble to improve production efficiency is also the main content of the research of this invention.

In this embodiment, as shown in Figure 1, the embodiment of the present invention provides a contact charging electrode structure for an electronic cigarette, including a charging PCB board 3 and an electronic cigarette electrode contact head 4. The charging PCB board 3 has a connection welded on one side. The USB interface 30 of the charging power supply has a positive spring 31 and a negative spring 32 welded to the other side of the charging PCB board 3. After bending, the positive spring 31 and the negative spring 32 respectively physically contact the electronic cigarette electrode contact head. The positive electrode 41 and the negative electrode 42, the charging PCB board 3 and the electronic cigarette electrode contact head 4 are fixed in the insert body, and together constitute an electronic cigarette charger, as shown in Figure 2-1 and Figure 2-2. The embedded body includes a face shell 1 and a bottom shell 2. The face shell 1 is provided with an electrode clamp solid 11 inside for fixing the positive electrode spring 31 and the negative electrode spring 32 and for fixing the electronic cigarette electrode contact head 4. .

The existing technology in contrast to Figure 1, as shown in Figure 3, uses welding between the charging PCB board 3 and the electronic cigarette electrode contact head 4 in Figure 1. Whether it is manual welding or machine welding, most of them are Soft wire or hard wire 34, but the real welding area is limited, only the small area covered by the solder. During the long-term use of the product, as the electronic cigarette rotates when charging and inserting, the electronic cigarette electrode contact head 4 is a driven force. Generally speaking, the welding joint between the charging PCB board 3 and the electronic cigarette electrode contact head 4 is prone to aging, poor contact or even detachment, causing the product to be directly discarded or repaired, and the quality of the product is reduced. Aiming at the defects of the welding type, the present invention proposes a new electrode structure. Because the conductive area of the contact type is much higher than the welding area of the welding type, it ensures that the positive electrode spring 31 and the negative electrode spring 32 are in multi-directional contact with the electronic cigarette electrode contact head 4 And strong enough.

Below, in order to more completely demonstrate this new electrode structure, this embodiment describes in detail the electronic cigarette charger in Figures 2-1 and 2-2 that adopts this structure:

In Figures 2-1, 2-2, 5-1, and 5-2, the positive electrode 41 is on the inside and the negative electrode 42 is on the outside to form a concentric cylinder. They are separated by an insulating medium 43 , and the positive contact pillar 431 on the positive electrode 41 that extends beyond the negative electrode 42 is used for physical contact with the positive spring 31 . The negative electrode 42 is provided with a first circumferential barrier 421, a second circumferential barrier 422 and a second circumferential barrier 422 that surround the negative electrode 42 along the other side along the side of the positive contact cylinder 431. The third circumferential barrier 423 of the two circumferential barriers 422, and a negative contact channel 4212 is formed between the first circumferential barrier 421 and the second circumferential barrier 422, and the negative contact channel 4212 is used to communicate with the The negative spring 32 is in physical contact, and the first circumferential blocking wall 421 is provided with anti-rotation gaps 4211. Multiple anti-rotation gaps 4211 may be provided evenly or unevenly. In this embodiment, two symmetrical ones are provided. As shown in Figure 5-2, there is another anti-rotation notch 4211 symmetrically positioned as can be seen in Figure 5-2. And the height of the second circumferential barrier 422 is greater than the height of the first circumferential barrier 421 and the third circumferential barrier 423, because the purpose of setting the second circumferential barrier 422 is to protect the electronic cigarette. The electrode contact head 4 can be fixed at a specific position. If the height is higher, corresponding channels are provided in the surface case 1 and the bottom case 2 so that it can be embedded in them without affecting the positive electrode spring 31 and the negative electrode spring 32 Physically contact the positive electrode 41 and the negative electrode 42 of the electronic cigarette electrode contact head 4, which will be described later.

As shown in Figures 2-1, 2-2, and 4-2, matching the positive electrode 41 of the electronic cigarette electrode contact head 4, the positive spring 31 is bent to form a spring for clamping the positive contact post. The body 431 has a "ji"-shaped bend 311 (the one seen directly in Figure 2-2 is an inverted "ji"-shaped bend, which is just a different viewing angle). The electrode clamp solid body 11 contains the "ji"-shaped bend embedded in the "ji"-shaped bend 311. The bending clamping groove 111 of the "ji"-shaped bend 311. Here, the tail end of the positive electrode contact cylinder 431 is provided with a positive electrode circumferential blocking wall 4311, which is used to block the "ji"-shaped bend 311, because the positive electrode spring 31 is made of commonly used spring materials and has a smooth surface. The positive electrode contact cylinder 431 is made of conductive hardware and has a similarly smooth surface. If the positive electrode circumferential barrier 4311 is not provided, if the The bend 311 undergoes inelastic deformation, and the positive electrode 41 irreversibly slides away from the "J"-shaped bend 311, which directly causes the positive spring 31 to no longer contact and conduct the positive electrode 41, resulting in damage.

Matching the negative electrode 42 of the electronic cigarette electrode contact head 4, the negative electrode spring 32 is bent to form an arc-shaped bend 321 for inserting into the negative electrode contact channel 4212 and making physical contact, and this The arc length of the arc-shaped bend 321 includes a large semicircle, and its diameter should be equal to or slightly smaller than the diameter of the portion of the negative electrode 42 corresponding to the negative electrode contact channel 4212.

Matching the positive electrode spring 31, the negative electrode spring 32, and the electronic cigarette electrode contact head 4, the electrode clamp solid body 11 also includes a rotation limiting wall 112 for being embedded in the anti-rotation notch 4211. The first arc barrier wall 113 is used to receive the negative electrode contact channel 4212 and the second arc barrier wall 114 is used to receive the third circumferential barrier wall 423 . A first barrier channel 1134 for fitting the second circumferential barrier 422 is formed between the first arc barrier wall 113 and the second arc barrier wall 114 . The bottom shell 2 is provided with a third arc barrier wall 213 and a fourth arc barrier wall 214 that snap together with the first arc barrier wall 113 and the second arc barrier wall 114 to form a circle, and A second barrier channel 2134 that fits the second circumferential barrier 422 is formed between the third arc barrier wall 213 and the fourth arc barrier wall 214. The second barrier channel 2134 is connected with the second arc barrier wall 422. The first blocking wall channel 1134 snaps together to form a circumferential channel for fitting the second circumferential blocking wall 422 . When the four parts of the surface case 1, the bottom case 2, the charging PCB board 3, and the electronic cigarette electrode contact head 4 are assembled, the second circumferential blocking wall 422 is all fitted into the circumferential channel, tightly strict.

As shown in Figure 4-2 and Figure 5-2, in order to completely separate the positive electrode spring 31 and the first circumferential blocking wall 421 to avoid electrical connection, the surface shell 1 is provided with a corresponding position corresponding to the positive electrode spring 31 and the negative electrode. The spring isolation wall 12 in the gap between the springs 32.

As shown in Figure 2-1, in order to completely separate the electronic cigarette electrode contact head 4 and the charging PCB board 3 to avoid electrical connection, the bottom case 2 is provided with a positive electrode contact cylinder 431 inside. The semicircular blocking wall 22 that resists the electronic cigarette electrode contact head 4 also plays a retaining role to a certain extent. At the same time, because the center of the semicircular blocking wall 22 coincides with the center of the cross section of the positive electrode contact cylinder 431 that is in contact with the semicircular blocking wall 22 , there is an empty space at the center of the semicircular blocking wall 22 with a radius equal to The positive electrode contact cylinder 431 is a semicircle 211 with the same radius, so as to be able to just receive the positive electrode contact cylinder 431 .

The above is the preferred embodiment of the present invention. It should be pointed out that for those of ordinary skill in the art, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also regarded as It is the protection scope of the present invention.
