Description

Cigarette cartridge

Technical Field

The present application relates to the field of electronic products, and in particular, to a cartridge for an electronic cigarette.

Background

With the stricter and stricter regulations and restrictions of tobacco products in various regions and governments around the world, the demand of people for tobacco substitutes is continuously growing. The e-vapor device may be a tobacco substitute that atomizes a nebulizable material (e.g., tobacco tar) by an e-aerosol generating device or an e-atomizing device to generate an aerosol for inhalation by a user to achieve a sensory experience that simulates smoking. Compared with the traditional tobacco products, the electronic cigarette device can effectively reduce harmful substances generated by combustion as a substitute thereof, and further reduce harmful side effects of smoking.

In electronic cigarette products using replaceable cartridges, electrical contact elements are typically provided to conduct electrical power into the cartridges, however poor electrical contact element design results in poor electrical power conduction efficiency, which in turn leads to inconsistent atomization of the tobacco tar within the cartridges, resulting in poor use experience.

SUMMERY OF THE UTILITY MODEL

It is an object of the present application to provide a cartridge to solve the problems of the background art.

According to an embodiment of the present application, a cartridge for an electronic cigarette is disclosed. The cartridge includes a housing having an opening and a base enclosing the opening. The base is provided with an air inlet area and an electric contact element. The electrical contact element has an electrical contact surface exposed at an outer surface of the base. The two sides of the air inlet area are respectively provided with the electric contact surfaces, and the size range of the electric contact surfaces along the length direction of the base is 3-5.5 mm.

Fig. 3A, 3B, 3C, and 3D demonstrate exemplary front, side, top, and perspective schematic views of acartridge 100A according to some embodiments of the present application.

Thecartridge 100A comprises acartridge housing 1 and abase 9, wherein the bottom of thecartridge housing 1 has an opening and thebase 9 is used to close the bottom opening of thecartridge housing 1. In some embodiments, thecartridge housing 1 has a mouthpiece cover (mouthpiece)1b thereon. In certain embodiments, thecartridge housing 1 andmouthpiece cover 1b may be two separate components. In some embodiments, themouthpiece cover 1b and thecartridge housing 1 may be made of different materials. In certain embodiments, themouthpiece cover 1b and thecartridge housing 1 may be integrally formed. In some embodiments, themouthpiece cover 1b and thecartridge housing 1 may be made of the same material.

Thecartridge housing 1 includes amating portion 1p for insertion into thebody 100B. Theengagement portion 1p is along the length direction of thecartridge case 1. In some embodiments, the dimension L of themating portion 1p ranges from 1.5mm to 2.5 mm. In some embodiments, the dimension L of themating portion 1p ranges from 1.8mm to 2.2 mm.

The aerosol generated by theatomizer 100 can be inhaled by the user through thetube 1t and theopening 1 h.

Fig. 4 illustrates an exploded view of thebase 9 according to some embodiments of the present application.

Thebase 9 comprises anair intake region 9a, theair intake region 9a comprising arecess 9a 1. The groove 9a1 is provided with an opening 9h1 and an opening 9h 2. The opening 9h1 and the opening 9h2 may be provided within the range of theintake region 9 a. The opening 9h1 and the opening 9h2 may be disposed within the range of thegroove 9a 1.

The opening 9h1 and the opening 9h2 communicate with the atomization chamber inside thecartridge 100A. The opening 9h1 and the opening 9h2 serve as air intake holes through which air can enter the interior of thecartridge 100A through the opening 9h1 and the opening 9h 2.

Thebase 9 further includes openings 9h3 and 9h4 provided on both sides of theair intake region 9 a. The electrical contact elements 9p1 and 9p2 can pass through the openings 9h3 and 9h4 respectively and be fixed on thebase 9. The electrical contact elements 9p1 and 9p2 pass through the openings 9h3 and 9h4 and extend into the interior of thecartridge 100A. The electrical contact elements 9p1 and 9p2 may have a function of conducting current. The electrical contact elements 9p1 and 9p2 may provide power to aerosol-generating components within thecartridge 100A. In certain embodiments, the aerosol-generating component within thecartridge 100A may be a heating component.

After the electrical contact elements 9p1 and 9p2 pass through the openings 9h3 and 9h4, the electrical contact surfaces 9s1 of the electrical contact elements 9p1 and the electrical contact surfaces 9s2 of the electrical contact elements 9p2 are exposed on the outer surface of thebase 9.

The electrical contacts 9p1 and 9p2 may comprise metal. The electrical contact elements 9p1 and 9p2 can be attracted by the magnetic elements. Thecartridge 100A may be attracted by magnetic elements disposed within thebody 100B via the electrical contact elements 9p1 and 9p 2. Thecartridge 100A may be removably coupled with thebody 100B via the electrical contact elements 9p1 and 9p 2.

Understandably, when the magnetic forces of the magnetic elements in thebody 100B are equal, if the areas of the electrical contact surfaces 9s1 of the electrical contact elements 9p1 and 9s2 of the electrical contact elements 9p2 are large, the attraction force between thebody 100B and thecartridge 100A is even when thecartridge 100A is attracted by the magnetic elements in thebody 100B, and therefore, thecartridge 100A is less likely to be detached from thebody 100B.

It should be noted that the present application does not limit the number of openings in the groove 9a1 as the air intake holes. In some embodiments, the recess 9a1 includes an opening. In some embodiments, three or more openings are provided in therecess 9a 1. In addition, the present application does not limit the number of electrical contact elements provided on thebase 9. In some embodiments, thebase 9 is provided with an electrical contact element. In some embodiments, three or more electrical contact elements are provided on thebase 9.

Fig. 5 illustrates a bottom view of thebase 9 according to some embodiments of the present application.

In some embodiments, the dimension r1 of the electrical contact surfaces 9s1 and 9s2 along the length of the base 9 (i.e., in the direction of the dashed line A-A') is in the range of 3mm to 5.5 mm. In some embodiments, the dimension r1 of the electrical contact surface 9s1 and the electrical contact surface 9s2 along the length of the base 9 (i.e., in the direction of the dashed line A-A') is in the range of 5mm to 5.1 mm. In some embodiments, the dimension r2 of the recess 9a1 along the length of the submount 9 (i.e., the direction of the dashed line A-A ') is not greater than the dimension r1 of the electrical contact faces 9s1 and 9s2 along the length of the submount 9 (i.e., the direction of the dashed line A-A'). In certain embodiments, the difference between dimension r1 and dimension r2 is no greater than 0.5 mm.

In certain embodiments, the recess 9a1 is circular. In certain embodiments, the groove 9a1 is annular. In certain embodiments, electrical contact surfaces 9s1 and electrical contact surfaces 9s2 are circular. In certain embodiments, the groove 9a1, electrical contact surface 9s1, and electrical contact surface 9s2 are circular.

In some embodiments, the center points of the openings 9h1 and 9h2 are aligned with the electrical contact surfaces 9s1 and 9s 2. In some embodiments, the center points of the opening 9h1 and the opening 9h2 and the center points of the electrical contact surfaces 9s1 and the electrical contact surfaces 9s2 are located along a line in the length direction (i.e., the direction of the dotted line a-a') of thebase 9. In some embodiments, the outer surface of thebase 9 is oval, in other words, the length direction of thebase 9 is the major axis of thebase 9. With this arrangement, the center point of the opening 9h1, the center point of the opening 9h2, the center point of the electrical contact surface 9s1, and the center point of the electrical contact surface 9s2 are located on the long axis of thebase 9.

The outer surface of thebase 9 exhibits an elliptical shape with a center O. In some embodiments, openings 9h1 and 9h2 are distributed around center O. However, the distribution of the openings 9h1 and 9h2 is not a limitation of the present application. In some embodiments, the opening of at least one of the grooves 9a1, which acts as an air inlet hole, may coincide with the center O of the ellipse.

Due to the limited area of thebase 9, the design of the size of the areas of the electrical contact surfaces 9s1 and 9s2 will affect the conduction of electrical power into thecartridge 100A. In detail, if the areas of the electrical contact surfaces 9s1 and 9s2 are small, the resistance formed by the electrical contact surfaces is large, the loss of electric power is large, the electric power conduction efficiency is poor, and the atomization effect of the tobacco tar is affected. Meanwhile, if the areas of the electrical contact surface 9s1 and the electrical contact surface 9s2 are small, the attractive magnetic force between thecartridge 100A and themain body 100B is relatively uneven, and thecartridge 100A is likely to fall off.

On the other hand, if the areas of the electrical contact surface 9s1 and the electrical contact surface 9s2 are too large, the areas are compressed into the space of theair intake region 9a, and further the distribution and the area of the openings 9h1 and 9h2 are affected, which also affects the atomization effect of the soot.

In view of the above, after experiments, the applicant found that when the dimensions r1 of the electrical contact surfaces 9s1 and 9s2 along the length direction of thebase 9 are designed to be in the range of 3mm to 5.5mm, the conduction of electric power and the magnetic force absorption are most appropriate, and at the same time, the amount of air entering thecartridge 100A is not affected. Under the design, a user can have better use experience.
