Technical Field

[0001] The present invention relates to the technical field of new energy batteries, and in particular to a battery, an atomization device and a battery preparation process. Background Art

[0002] Traditional steel-shell secondary lithium-ion batteries and sodium-ion batteries use the steel shell plus explosion-proof valve structure of Panasonic 18650 batteries. This type of battery has three main disadvantages when used in new electronic products. First, the positive and negative poles of the battery are on opposite sides. When in use, the battery often needs to be changed to the same direction through welding, which will increase the welding points and resistance; second, the battery has no supporting part when connected to the electronic product, and an external bracket is required for fixed connection; third, the battery needs to be welded with a protection plate when connected to the circuit board to prevent the battery from short circuiting, over-discharging and overcharging. The process of welding the protection plate is complicated and there are many welding points, which increases the resistance of the electronic product. In addition, there are many welding points, which will increase the unreliability of the product. There are at least 4 welding points connecting the battery to the protection board and the circuit board, and two wires leading to the electrodes. The resistance of each welding point is about 10mΩ, and each wire also has resistance. The more welding points and wires there are in the circuit connecting the electronic product and the battery, the greater the circuit resistance.

[0003] This structure is currently used in rod-type detachable products, which makes the product design very complicated, with many solder joints, increasing the resistance in the circuit, thereby increasing the ineffective part of the circuit and reducing the power of the effective part of the circuit. Therefore, a new structural battery is designed that is convenient for use in rod-type electronic products. Summary of the invention

[0004] The technical problem to be solved by the embodiments of the present invention is that the positive and negative poles of traditional batteries are in different directions, and the connection with electronic products requires welding for auxiliary fixation, which requires additional auxiliary fixing structures, additional welding points and wires to increase the resistance in the circuit, resulting in a complex product structure, larger volume, and large ineffective resistance in the circuit and excessive heat generation.

[0005] In order to solve the above problems, an embodiment of the present invention discloses a battery. The battery can be connected to an electronic product in a contact manner, and the structure between the auxiliary fixing structure and the electrode can fix the battery and the main body of the electronic product together, without the need to mechanically fix them in the auxiliary fixing structure by gluing or screws. The electronic product can reduce welding points, thereby achieving the effect of reducing the resistance of the entire circuit.

The specific description of each component is as follows:

[0053] In this embodiment, the shell 1 is a cylindrical structure with a one-way opening, and the cross section of the shell 1 is any one of a circular, elliptical, and prismatic shape. It should be noted that the cross-sectional shape of the shell 1 is any one of a circular, elliptical, and prismatic shape is only an example. Those skilled in the art can also use shells 1 with other cross-sectional shapes, which will not exceed the protection scope of the present invention. The opening side of the shell 1 is the upper side, and the bottom of the shell 1 is the lower side. The battery cell 2 includes a package core body and a winding core (the winding core is also called a semi-finished battery cell 2). The battery cell 2 is electrically connected to the circuit board 3. The circuit board 3 includes a PCB board. The outer contour of the circuit board 3 is embedded with the inner wall of the shell 1, so that the circuit board 3 is installed directly above the battery cell 2.

The battery is embedded with the electronic product through the groove to increase the sealing and firmness of the connection. In one embodiment, the opening of the housing 1 is higher than the top of the conductive member, so that when the positive and negative electrodes of the battery are docked or dropped, the positive and negative electrodes of the battery are prevented from contacting the conductor at the same time, causing a short circuit and fire of the battery.

[0054] The resistance generated by the solder joint is generally between 8mΩ and 100mΩ. The resistance of the solder joint is affected by the material and the soldering area. A good solder joint resistance is about 10mΩ. The conductive member is installed on the circuit board 3, and the circuit board 3 is covered on the battery cell 2. The conductive member serves as the electrode of the battery to prevent the circuit board 3 from being connected to the positive and negative electrodes of the battery through wires, thereby reducing the number of solder joints and thus reducing the circuit resistance of the entire product.

[0055] Continue to see Figure 3-7 In this embodiment, the second packaging component further includes an insulating component 8 , and the insulating component 8 is disposed on one side of the circuit board 3 .

[0056] Specifically, the insulating member 8 is a soft material and is installed at the bottom of the circuit board 3. In this embodiment, the battery cell 2 is encapsulated in the shell 1 by the insulating member 8. The insulating member 8 and the rigid PCB circuit board 3 together constitute a new explosion-proof valve. It should be noted that the soft insulating material can be used as the sealing layer, insulating layer and explosion-proof layer of the battery. The specific principle can be determined by referring to existing data. The present invention does not make specific limitations on this. PCBA serves as the strength support layer of the explosion valve. The second package obtained by the circuit board 3-insulating member 8 can replace the traditional explosion-proof valve, which can effectively improve the safety performance of the battery and reduce the resistance of the battery. Usually, when the battery cell 2 uses a winding core, adding an insulating member 8 can effectively improve the safety performance of the battery.

[0057] Furthermore, a limiting portion 12 is provided on the inner wall of the housing 1 , and the insulating member 8 is provided on the limiting portion 12 .

If the user stops inhaling, the airflow in the sensor will disappear, the airflow sensor will automatically turn off, and the control circuit will stop working and no steam will appear. The specific principle of starting and stopping the components on the control circuit through the airflow sensor can be determined by referring to existing materials, and the present invention does not make specific limitations on this.

[0063] Furthermore, it also includes an LED lamp, which is arranged on the circuit board 3.

[0064] Specifically, the LED light is turned on and off by a switch. For example, in one embodiment, by switching on and off the airflow sensor, an airflow sensing switch is formed by the airflow sensor, so that when the user inhales, the airflow sensor, that is, the microphone, will respond to trigger the control circuit, and the light will turn on and start working. If the user blows three times in a row to stop the current, the airflow sensor will automatically turn off, and the control circuit will also stop working and the LED light will turn off.

In one embodiment, a light-emitting device is provided on one side of the opening 61. For example, the light-emitting device is mounted on the battery to emit light to show the battery power status. The light of the light-emitting device can be seen through the opening 61.

[0078] It also includes a sealing connection member 4, which covers the opening.

[0079] Specifically, the sealing connector 4 is usually made of a soft material and is used to cover the opening of the shell 1.

[0083] Furthermore, the outer diameter of the retaining ring 41 is equal to the outer diameter of the opening.

[0084] Specifically, the outer diameter of the retaining ring 41 is equal to the outer diameter of the opening, so that the battery and the sealing connector 4 can be installed into the battery compartment of the electronic product respectively.

[0085] In this embodiment, the main working part of the atomizer is the heating wire. In the circuit of the entire product, if the resistance is not variable, the greater the current, the better the heating effect of the heating wire, that is, the greater the current, the better the atomizer atomization effect.
