In this embodiment, as shown in fig. 1, the embodiment of the invention provides a contact type charging electrode structure of an electronic cigarette, which comprises a charging PCB 3 and an electronic cigarette electrode contact 4, wherein a USB interface 30 connected with a charging power supply is welded on one side of the charging PCB 3, an anode spring 31 and a cathode spring 32 are welded on the other side of the charging PCB 3, the anode spring 31 and the cathode spring 32 are respectively and physically contacted with an anode electrode 41 and a cathode electrode 42 of the electronic cigarette electrode contact after being bent, the charging PCB 3 and the electronic cigarette electrode contact 4 are fixed in a clamping body, so as to jointly form an electronic cigarette charger, as shown in fig. 2-1 and fig. 2-2, the clamping body comprises a face shell 1 and a bottom shell 2, and electrode clamp solids 11 for fixing the anode spring 31 and the cathode spring 32 and for fixing the electronic cigarette electrode contact 4 are arranged in the face shell 1.
Compared with the prior art in fig. 1, as shown in fig. 3, for the welding mode between the charging PCB 3 and the electrode contact 4 of fig. 1, no matter manual welding or machine welding is adopted, most of soft wires or hard wires 34 are adopted, but the real welding area is limited, only the small area covered by soldering tin is adopted, and in the long-term use process of the product, the electrode contact 4 of the electronic cigarette is driven along with the rotation of the charging and inserting of the electronic cigarette, and in general, the welding position between the charging PCB 3 and the electrode contact 4 of the electronic cigarette is easy to age, poor in contact and even separate, so that the product is directly discarded or reworked, and the quality of the product is reduced. Aiming at the defect of welding type, the invention provides a novel electrode structure, because the contact type conductive area is greatly higher than the welding area of welding type, the positive electrode spring 31 and the negative electrode spring 32 are ensured to be contacted with the electrode contact head 4 of the electronic cigarette in multiple directions and are firm enough.
In order to more completely reveal this new electrode structure, the following describes in detail the electronic cigarette charger in fig. 2-1 and fig. 2-2 using this structure:
in fig. 2-1, 2-2, 5-1, 5-2, the positive electrode 41 and the negative electrode 42 together form a concentric cylinder, the positive electrode 41 and the negative electrode 42 are separated by an insulating medium 43, and a positive contact cylinder 431 on the positive electrode 41 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 blocking wall 421, a second circumferential blocking wall 422 and a third circumferential blocking wall 423 attached to the second circumferential blocking wall 422, which are sequentially disposed on one side of the positive electrode contact column 431 along the other side, wherein the first circumferential blocking wall 421 and the second circumferential blocking wall 422 are surrounded by the negative electrode 42, a negative electrode contact channel 4212 is formed between the first circumferential blocking wall 421 and the second circumferential blocking wall 422, the negative electrode contact channel 4212 is used for being in physical contact with the negative electrode spring 32, the first circumferential blocking wall 421 is provided with anti-rotation notches 4211, the anti-rotation notches 4211 may be uniformly or unevenly provided with a plurality of anti-rotation notches 4211, and in this embodiment, two symmetrical positions are also provided with one symmetrical position, as can be seen in fig. 5-2, with the anti-rotation notches 4211. And the height of the second circumferential blocking wall 422 is greater than the heights of the first circumferential blocking wall 421 and the third circumferential blocking wall 423, because the purpose of the second circumferential blocking wall 422 is to fix a specific position of the electronic cigarette electrode contact 4, and if the height is higher, channels corresponding to the two are provided in the face case 1 and the bottom case 2 to be embedded therein, so that the positive electrode 41 and the negative electrode 42 of the electronic cigarette electrode contact 4 are not affected by the physical contact between the positive electrode spring 31 and the negative electrode spring 32, which will be described later.
As shown in fig. 2-1, 2-2 and 4-2, in matching with the positive electrode 41 of the electronic cigarette electrode contact 4, the positive electrode spring 31 is bent to form a "several" shaped bend 311 (the "several" shaped bend is inverted when directly seen in fig. 2-2, only the angle of view is different), the electrode clamp solid 11 includes a bending clamp solid groove 111 embedded in the "several" shaped bend 311, where the tail end of the positive electrode contact cylinder 431 is provided with a positive electrode circumferential blocking wall 4311 for blocking the "several" shaped bend 311, because the positive electrode spring 31 is formed by bending a common spring material, the surface is smooth, and the conductive hardware material adopted by the positive electrode contact cylinder 431 is also smooth, if the "several" shaped bend 311 is not provided, the electrode 41 cannot be restored to slide away from the "several" shaped bend 4311, which directly causes the positive electrode spring 31 to be not conductive any more, resulting in damage to the positive electrode 41.
In correspondence with the negative electrode 42 of the electronic cigarette electrode contact 4, the negative spring 32 is bent to form a circular arc bend 321 for embedding in and physically contacting the negative contact channel 4212, and the circular arc bend 321 has an arc length including a major semicircle, and its diameter should be equal to or slightly smaller than the diameter of a portion of the negative electrode 42 corresponding to the negative contact channel 4212.
The electrode holder body 11 further includes a rotation limiting wall 112 for being embedded in the anti-rotation notch 4211, a first arc blocking wall 113 for receiving the negative electrode contact channel 4212, and a second arc blocking wall 114 for receiving the third circumference blocking wall 423, which are matched with the positive electrode spring 31, the negative electrode spring 32, and the electronic cigarette electrode contact head 4. The first circular arc wall 113 and the second circular arc wall 114 form a first wall channel 1134 for engaging the second circular arc wall 422. The bottom shell 2 is internally provided with a third arc blocking wall 213 and a fourth arc blocking wall 214 which are buckled with the first arc blocking wall 113 and the second arc blocking wall 114 to form a circumference, a second blocking wall channel 2134 which is embedded with the second circumference blocking wall 422 is formed between the third arc blocking wall 213 and the fourth arc blocking wall 214, and the second blocking wall channel 2134 is buckled with the first blocking wall channel 1134 to form a circumference channel for embedded with the second circumference blocking wall 422. When the four parts of the face shell 1, the bottom shell 2, the charging PCB 3 and the electronic cigarette electrode contact 4 are assembled, the second circumferential blocking walls 422 are all embedded in the circumferential channels, so that the face shell is compact.
As shown in fig. 4-2 and 5-2, in order to completely separate the positive electrode spring 31 from the first circumferential blocking wall 421 so as not to be electrically connected, the inside of the face case 1 is provided with a spring isolation wall 12 corresponding to a gap between the positive electrode spring 31 and the negative electrode spring 32.
As shown in fig. 2-1, in order to thoroughly separate the electrode contact 4 from the charging PCB 3, so as not to be electrically connected, the bottom shell 2 is internally provided with a semicircular blocking wall 22 for engaging the positive electrode contact cylinder 431 and resisting the electrode contact 4, which also plays a role in retaining to a certain extent. Meanwhile, because the center of the semicircular blocking wall 22 coincides with the center of the cross section of the positive electrode contact cylinder 431, which is in contact with the semicircular blocking wall 22, a semicircle 211 with the same radius as the positive electrode contact cylinder 431 is left at the center of the semicircular blocking wall 22, so as to be capable of just receiving the positive electrode contact cylinder 431.
While the foregoing is directed to the preferred embodiments of the present invention, it will be appreciated by those skilled in the art that changes and modifications may be made without departing from the principles of the invention, such changes and modifications are also intended to be within the scope of the invention.
