Description

Technical Field

[0001] The utility model relates to the technical field of electronic cigarette batteries, and in particular to a detachable battery power supply connection structure and an electronic cigarette. Background Art

[0002] Soft-pack batteries have many advantages such as small size, light weight, high specific energy, and relatively flexible design. They are particularly widely used in e-cigarettes. However, the connection between soft-pack batteries and cigarette rods in e-cigarettes is generally soldered, which is a non-user-removable assembly method. This will seriously affect the use cycle of e-cigarette products. Non-removable batteries are more difficult to recycle and are often directly discarded with e-cigarette products, causing environmental pollution. According to the EU's new battery (EU) 2023 / 1542 regulations, all portable batteries should adopt a removable battery design, and consumers can disassemble, remove or replace the battery by themselves without using special tools (such as solvents, heating) or undergoing training.

[0003] In addition, since the discharge current of e-cigarettes is generally between 1.2A and 30A, if the soft-pack battery adopts the traditional press-type contact structure, its contact resistance is large. When the battery is powering, the contact surface will cause the voltage drop to increase, making it difficult to ensure stable and continuous high current transmission requirements.

[0004] Therefore, it is urgent to develop a detachable connection structure that can solve the problem of large voltage drop on the contact surface of soft-pack batteries. Utility Model Content

[0005] The purpose of the utility model is to provide a detachable battery-powered connection structure and an electronic cigarette. The connection structure has a reasonable design and a simple preparation method, which is conducive to the detachability of the soft-pack battery in the electronic cigarette battery compartment. At the same time, the connection structure reduces the contact resistance of the contact surface, making the voltage drop of the contact surface lower, and meeting the requirements of large current transmission.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] In the first aspect, the utility model provides a detachable battery power supply connection structure, comprising: a hard shell, a soft-pack battery, a positive elastic sheet, a negative elastic sheet, a positive current collector sheet, and a negative current collector sheet, wherein the soft-pack battery is installed inside the hard shell; the upper end of the soft-pack battery is the positive electrode of the soft-pack battery, and the lower end of the soft-pack battery is the negative electrode of the soft-pack battery; a positive elastic sheet is arranged at one end of the hard shell close to the positive electrode of the soft-pack battery, and a positive elastic sheet is arranged at one end of the hard shell close to the negative electrode of the soft-pack battery. A negative electrode elastic sheet is provided at one end; a positive electrode collector sheet having the same shape as the positive electrode elastic sheet is covered on the surface of the positive electrode elastic sheet away from the positive electrode of the soft-pack battery, and a negative electrode collector sheet having the same shape as the negative electrode elastic sheet is covered on the surface of the negative electrode elastic sheet away from the negative electrode of the soft-pack battery; the positive electrode collector sheet is electrically connected to the positive electrode of the soft-pack battery, and the negative electrode collector sheet is electrically connected to the negative electrode of the soft-pack battery.

[0008] In the second aspect, the utility model provides an electronic cigarette, the cigarette rod of the electronic cigarette is provided with a battery compartment and a solution board; the battery compartment is provided with the aforementioned detachable battery power supply connection structure, a first smooth metal plane electrically connected to the main unit of the electronic cigarette, and a second smooth metal plane electrically connected to the main unit of the electronic cigarette; the first smooth metal plane forms a planar contact with the positive electrode collector sheet, and the second smooth metal plane forms a planar contact with the negative electrode collector sheet.

[0009] The beneficial effects of the utility model are as follows:

[0010] (1) The detachable battery power supply connection structure provided by the utility model has a hard shell that wraps the soft-pack battery, which can play a good protective role and increase the battery vibration resistance of the original soft-pack battery. When the electronic cigarette falls, the battery will not be damaged, thereby extending the service life of the electronic cigarette and improving the reliability, stability and safety of the battery contact; at the same time, the hard shell separates the soft-pack battery from the main body of the electronic cigarette to achieve the purpose of detachability and facilitate the recycling and reuse of the soft-pack battery. The elastic sheet and the current collector sheet combination structure located at both ends of the hard shell are respectively electrically connected to the positive electrode, the negative electrode and the cigarette rod of the electronic cigarette to ensure that the soft-pack battery is used to power the electronic cigarette main body.

[0011] (2) The detachable battery-powered connection structure provided by the utility model has the current collector sheets at both ends supporting the smooth metal surface of the electronic cigarette rod. Due to the presence of the elastic sheet, the current collector sheet and the smooth metal surface are in good contact, which further increases the contact area between the two, reduces the contact resistance, meets the requirements of large current passing, and greatly reduces the voltage drop on the contact surface.
