DETAILED DESCRIPTION
An object of the present application is to provide an electronic cigarette, which has a high assembling reliability and is not apt to cause oil leakage.
In order that those skilled in the art can better understand technical solutions according to the present application, the present application will be explained in detail in conjunction with the accompanying drawings and the embodiments below.
Referring to FIG. 1, it is an assembly structural schematic view illustrating a structure of an electronic cigarette according to an embodiment of the present application;
In an embodiment, an electronic cigarette according to the present application includes an atomizer assembly 11 and a battery assembly 12 cooperated with each other. An atomizer assembly protective cartridge 21 is provided outside of the atomizer assembly 11, and a battery assembly protective cartridge 22 is provided outside of the battery assembly 12. The atomizer assembly protective cartridge 21 is connected to the battery assembly protective cartridge 22 via a holder 23. An atomizing seat 111 fitted with the holder 23 is provided at an inner end of the atomizer assembly 11. At least a coating layer 24 is provided outside of the atomizer assembly protective cartridge 21, the holder 23 and the battery assembly protective cartridge 22; and enables the connection of the atomizer assembly protective cartridge 21, the holder 23 and the battery assembly protective cartridge 22. In operation, the atomizer assembly 11 is mounted in the atomizer assembly protective cartridge 21, and the battery assembly 12 is mounted in the battery assembly protective cartridge 22, and then the atomizer assembly protective cartridge 21 is connected to the battery assembly protective cartridge 22 by the holder 23 and the coating layer 24, so as to finish assembling. In the overall process of assembling, since there is no pushing or squeezing action between the atomizer assembly and the battery assembly, it is possible to effectively avoid oil leakage caused by an inclination and a deformation of the atomizing seat under uneven force is effectively avoided, and overall assembly structure of the electronic cigarette is stable and reliable.
Further, there is the interference fit between the holder 23 and the atomizer assembly protective cartridge 21 as well as the battery assembly protective cartridge 22. Such interference fit could significantly enhance reliability and stability of the assembly structure between the holder 23 and the atomizer assembly protective cartridge 21 as well as the battery assembly protective cartridge 22, thereby enabling the overall structure of the electronic cigarette to be firmer and more stable.
Specifically, an air intake 231 communicating with external environment is provided in the holder 23. In use of the electronic cigarette, outside air is sucked in through the air intake 231 to maintain a normal working process of the electronic cigarette.
More specifically, a first air hole (not shown) communicating with the air intake 231 is provided in the battery assembly protective cartridge 22 or the atomizer assembly protective cartridge 21; and a second air hole (not shown) communicating with the air intake 231 is provided in the coating layer 24. The first air hole and the second air hole could communicate with the air intake 231 one another, thereby having an intake process of the electronic cigarette smoother.
On the other hand, an air inlet (not shown) communicating with external environment is provided in an outer end of the battery assembly protective cartridge 22. Since the air inlet is provided in the outer end of the battery assembly protective cartridge 22, i.e. the end, far away from a suction nozzle, of the overall structure of the electronic cigarette, it is possible to enhance an emulation effect of the electronic cigarette while ensuring an air intake process of the electronic cigarette, thereby improving the user's experiences accordingly.
Referring to FIG. 2, it is an assembly structural schematic view illustrating another structure of the electronic cigarette according to an embodiment of the present application.
On the other hand, the end of the holder 23 fitted with the atomizing seat 111 is provided with an inner plug-in section 232, and the end of the atomizing seat 111 fitted with the holder 23 is provided with an outer socket section 112. The holder 23 is fixed to the atomizing seat 111 by inserting the inner plug-in section 232 into the outer socket section 112. Such plug-socket mounting structure formed by a fit between the inner plug-in section 232 and the outer socket section 112 could effectively enhance stability and reliability of the assembly structure between the holder 23 and the atomizing seat 111, and have the assembly structure between the holder 23 and the atomizing seat 111 and the entire assembly structure of the electronic cigarette more stable and reliable.
Furthermore, the atomizer assembly protective cartridge 21 and the battery assembly protective cartridge 22 may be made of any one of the following materials: silicone, rubber, thermoplastic polyurethane (abbreviated as TPU hereinafter), thermoplastic elastomer (abbreviated as TPE hereinafter), thermoplastic rubber (abbreviated as TPR hereinafter), amorphous polyethylene terephthalate (abbreviated as APET hereinafter), polyvinyl chloride (abbreviated as PVC hereinafter), or polycarbonate (abbreviated as PC hereinafter). Such soft materials mentioned above may further optimize the protective effect of the atomizer assembly protective cartridge 21 on the atomizer assembly and the protective effect of the battery assembly protective cartridge 22 on the battery assembly, and improve the feeling of the user in using the electronic cigarette.
Further, the holder 23 may be made of any one of the following materials: silicone, rubber, TPU, TPE, TPR, APET, PVC, or PC. The material of the atomizer assembly protective cartridge 21, the battery assembly protective cartridge 22 and the holder 23 is not limited those listed, as long as it may meet the actual usage requirements of the electronic cigarette.
Furthermore, the coating layer 24 may be a paster. The paster has a low purchase cost, and is available largely on the market, and achieves better pasting and fixing effect, thereby meeting assembling requirements of the electronic cigarette while cutting down production costs thereof effectively.
In summary, the electronic cigarette according to the present application includes an atomizer assembly and a battery assembly cooperated with each other, wherein an atomizer assembly protective cartridge is provided outside of the atomizer assembly, a battery assembly protective cartridge is provided outside of the battery assembly, the atomizer assembly protective cartridge is connected to the battery assembly protective cartridge via a holder, an atomizing seat fitted with the holder is provided at an inner end of the atomizer assembly; at least a coating layer is provided outside of the atomizer assembly protective cartridge, the holder and the battery assembly protective cartridge; and enables the connection between the atomizer assembly protective cartridge, the holder and the battery assembly protective cartridge. In operation, the atomizer assembly is mounted in the atomizer assembly protective cartridge, and the battery assembly is mounted in the battery assembly protective cartridge, and then the atomizer assembly protective cartridge is connected to the battery assembly protective cartridge by the holder and the coating layer, so as to finish assembling. In the overall process of assembling, since there is no pushing or squeezing action between the atomizer assembly and the battery assembly, it is possible to effectively avoid oil leakage caused by an inclination and a deformation of the atomizing seat under uneven force is effectively avoided, and overall assembly structure of the electronic cigarette is stable and reliable.
