The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.
[0024] like Figures 1 to 4 As shown, the electronic cigarette battery of the embodiment of the utility model includes a battery cell 10, a positive pole ear 20, a negative pole ear 30, and a cap 40. The cap 40 is made of metal. The positive pole ear 20 and the negative pole ear 30 are electrically connected to the positive and negative poles of the battery cell 10 respectively. The cap 40 includes a first surface 41 and a second surface 42 opposite to the first surface 41. The first surface 41 includes a welding area 411 and a bonding area 412. The cap 40 is fixed to the positive and negative poles of the battery cell 10 respectively through the bonding area 412, and is electrically connected to the positive pole ear 20 and the negative pole ear 30 respectively through the welding area 411, and is electrically connected to the positive input terminal and the negative input terminal of the internal circuit of the electronic cigarette respectively through the second surface 42. The cap 40 includes a positive cap and a negative cap. The positive cap is installed on the positive side of the electronic cigarette battery, and the negative cap is installed on the negative side of the electronic cigarette battery. The positive cap and the negative cap have the same structure.
[0025] The electronic cigarette battery includes a battery cell, a positive pole ear, a negative pole ear, and a cap. The cap includes a first surface and a second surface. The first surface includes a welding area and a bonding area. The cap is fixed to the positive and negative sides of the battery cell through the bonding area, and is electrically connected to the positive pole ear and the negative pole ear through the welding area, and is electrically connected to the positive input terminal and the negative input terminal of the internal circuit of the electronic cigarette through the second surface. Since the cap is made of metal, the cap is electrically connected to the positive pole ear and the negative pole ear through the welding area, and the second surface of the cap is electrically connected to the positive input terminal and the negative input terminal of the internal circuit of the electronic cigarette, respectively, so that the positive pole ear and the negative pole ear can be electrically connected to the positive input terminal and the negative input terminal of the internal circuit of the electronic cigarette, respectively, so as to realize power supply. By arranging the cap on both sides of the positive and negative poles of the battery cell, the contact area between the positive and negative poles of the electronic cigarette battery and the positive input terminal and the negative input terminal of the internal circuit of the electronic cigarette is increased, so that the electronic cigarette battery has better contact and improves the working stability of the electronic cigarette.
[0026] Among them, the welding area 411 on the first surface 41 is a concave structure, and the area on the second surface 42 corresponding to the welding area 411 is a convex structure 421. The welding area 411 is set as a concave structure so that the positive pole tab 20 and the negative pole tab 30 can be respectively accommodated in the concave structure, and at the same time, the cap 40 is fixed to the positive and negative sides of the battery cell 10 through the bonding area 412, so that the connection between the cap 40 and the battery cell 10 is more secure. The welding area 411 can be welded to the positive pole tab 20 and the negative pole tab 30 respectively by an ultrasonic welder.
[0027] The shape of the battery cell 10 can be set according to actual needs. Preferably, the battery cell 10 is cylindrical, and the cap 40 is set to be circular to match the cylindrical battery cell 10.
[0028] The diameter of the cap 40 and the diameter of the cross section of the battery core 10 can be selected according to actual needs. Preferably, the diameter of the cap 40 is equal to the diameter of the cross section of the battery core 10. Setting the diameter of the cap 40 to be equal to the diameter of the cross section of the battery core 10 can better achieve electrical connection between the cap 40 and the positive pole tab 20 and the negative pole tab 30, and better achieve electrical connection between the cap 40 and the positive input terminal and the negative input terminal of the internal circuit of the electronic cigarette, thereby improving the stability of the contact between the electronic cigarette battery and the internal circuit of the electronic cigarette.
[0029] Among them, the concave structure of the welding area 411 and the convex structure 421 on the second surface 42 corresponding to the welding area 411 are both circular, and the center of the concave structure and the center of the convex structure 421 coincide with the geometric center of the first surface 41 and the geometric center of the second surface 42 respectively. Setting the concave structure and the convex structure 421 to be circular can better meet the production process requirements of the cap 40. At the same time, the center of the concave structure and the center of the convex structure 421 coincide with the geometric center of the first surface 41 and the geometric center of the second surface 42 respectively, which can make the structure of the electronic cigarette battery more stable.
[0030] The diameter of the first surface 41 is equal to the diameter of the second surface 42. The diameter of the concave structure and the diameter of the convex structure 421 can be set according to actual needs. Preferably, the diameter of the concave structure is half of the diameter of the first surface 41, and the diameter of the convex structure 421 is half of the diameter of the second surface 42.
[0031] Among them, the electronic cigarette battery is a soft pack battery, and the packaging material of the battery cell 10 can be selected according to the actual situation. Preferably, the packaging material of the battery cell 10 is an aluminum plastic film. The soft pack battery has excellent safety performance. In the event of a safety hazard, it will only bulge and crack, but will not explode. The aluminum plastic film has the characteristics of light weight and good sealing, and is suitable for use as a packaging material for soft pack batteries.
[0032] The bonding area 412 of the first surface 41 is an annular structure, and the bonding area 412 is connected to the battery cell 10 through an insulating adhesive. The bonding area 412 is connected to the battery cell 10 through the insulating adhesive to prevent the cap 40 from being connected to the aluminum-plastic film on the outer layer of the battery cell 10.
[0033] The electronic cigarette battery may further include a heat shrink film, which is disposed on the outer surface of the electronic cigarette battery and is used to lock the cap 40. The heat shrink film has the property of shrinking when heated, and will generate a shrinkage force, which can be used to lock the cap 40. The material of the cap 40 can be selected according to actual conditions. Preferably, the material of the cap 40 is metal nickel. The height of the cap 40 can be selected according to actual conditions. Preferably, the height of the cap 40 is 0.5 mm.
[0034] The electronic cigarette battery of the embodiment of the utility model can increase the contact area between the positive and negative electrodes of the electronic cigarette battery and the positive input terminal and the negative input terminal of the internal circuit of the electronic cigarette by arranging caps for connecting the positive electrode tab and the negative electrode tab on both sides of the positive and negative electrodes of the battery, thereby reducing the risk of poor contact of the electronic cigarette battery and improving the working stability of the electronic cigarette.
[0035] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
