Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the following detailed description, reference is made to the accompanying drawings that form a part hereof and in which is shown by way of illustration specific embodiments of the application. In the drawings, like numerals describe substantially similar components throughout the different views. Various specific embodiments of the present application are described in sufficient detail below to enable those skilled in the art to practice the teachings of the present application. It is to be understood that other embodiments may be utilized and structural, logical or electrical changes may be made to the embodiments of the present application.

In order to solve the problem of leakage of condensate, the flexible switch is designed and is installed inside a cigarette cartridge of an electronic cigarette, and the flexible switch is in an open state in the smoking process; after the pumping is finished, the device is automatically in a closed state, and the condensate can be effectively prevented from leaking.

Fig. 1A is a perspective view of a flexible switch according to one embodiment of the invention. As shown, the flexible switch 100 includes a switch body 110 and a flexible valve 120. Wherein. The flexible valve 120 is formed on the switch body 110, and when the air flow flows, the flexible valve 120 is opened under the action of the pressure difference; when the flow of gas stops, the flexible valve 120 automatically closes.

In some embodiments, the flexible valve 120 is a silicone valve, and two or more valves attached to each other are disposed on the flexible valve, and the valves deform under the action of the pressure difference to form a gap therebetween, so that the silicone valve opens, and when the pressure difference disappears, the valves return to the state of being attached to each other, so that the silicone valve closes. Adjacent valves on the silica gel valve are mutually attached, so that condensate leakage can be effectively prevented.

In some embodiments, the engaging portion of the flexible valve 120 and the switch body 110 is circular in outline, and the flexible valve 120 includes four valves which are equally circular. Side gaps among the four valves form a cross shape, and gaps are formed among the valves under the action of air pressure, so that air flow can pass through the gaps. Of course, there may be other numbers of valves, and different shapes of slits. However, the working principle is basically the same as that of the present application no matter how many valves are.

In some embodiments, the flexible valve bulges in the direction of gas flow. As shown in fig. 1, the valve is raised inward, and the valves are attached to each other to form a hemisphere. The flexible valve is hemispherical, and can automatically slide at the joint of the flexible valve 120 and the switch main body 110 under the gravity action of condensate/tobacco tar, so that the condensate/tobacco tar is prevented from permeating out through gaps between the valves.

In some embodiments, the switch body 110 includes a base 111 and a submount 112, the submount 112 being disposed on the base 111. The base 111 and the base 112 may be integrally formed or fixedly connected together, which is not limited herein.

In some embodiments, the switch body 110 is provided with an electrode hole 130, which penetrates the base 112 and the base 111. As shown in fig. 1, two electrode holes 130 are symmetrically disposed on the switch body 110 for receiving electrodes on the e-cigarette cartridge. It will be understood by those skilled in the art that if the electrodes do not need to pass through the flexible switch 100, the flexible switch may not have electrode holes, depending on the particular implementation.

In some embodiments, the flexible valve 120 is centrally located on the submount 112, and a groove 140 is provided around the flexible valve 120 below the submount 112. The groove 140 may be rectangular, circular, or irregular, and is not limited herein. A flexible valve 120 is secured to the bottom of the recess 140 to prevent condensate/soot leakage.

FIG. 1B is a schematic diagram of a flexible switch closed state according to one embodiment of the invention. Fig. 1C is a schematic diagram of an open state of a flexible switch according to an embodiment of the invention. As shown, the flexible switch 100 is fixed within the e-cigarette cartridge, dividing the air channel of the e-cigarette into two spaces. When the electronic cigarette is not in use, air pressure on two sides of the flexible switch is balanced, and the flexible switch is in a closed state; in the process of pumping of a user, the air pressure on one side suddenly decreases, and one end communicated with the atmospheric pressure presses the flexible switch to deform to form a gap, so that the air flow passes through the gap. After the user finishes pumping, the air pressures on the two sides are balanced, and the valve on the flexible switch automatically restores to the original shape, so that the flexible switch is in a closed state.

Figure 2 is a schematic diagram of the structure of an e-cigarette cartridge according to one embodiment of the invention. As shown, the e-cigarette cartridge 200 includes a housing 210, a heating device 220, an electrode 230, and a flexible switch 100. Wherein one end of the housing 210 includes an air outlet to release the smoke when the user inhales. The housing 210 encloses a space for containing the tobacco tar. The heating device 220 is used to heat the tobacco tar, thereby generating smoke. The heating device 220, the flexible switch 100, and the electrode 230 can be assembled in the housing 210.

In some embodiments, the flexible switch 100 is removably mounted between the electrode and the heating device 220. The heating device 220, the flexible switch 100, and the electrode 230 are assembled in turn in the case 210. The flexible switch 100 is not in direct contact with the heating means 220, and the electrode 230 is electrically connected with the heating means 220. The flexible switch 100 completely seals the air inlet in the closed state, preventing condensate/smoke from escaping from the air inlet of the electronic cigarette. In some cases, the electronic cigarette may leak the tobacco tar through the air inlet during use, and thus the flexible switch may also prevent the tobacco tar from leaking.

In other embodiments, the flexible switch 100 is removably mounted between the heating device 220 and the air outlet of the housing 210. The flexible switch 100, the heating means 220 and the electrodes 230 are assembled in turn in the housing 210. At this moment, the flexible switch can prevent the condensate from flowing out of the air outlet, and user experience is improved.

In some embodiments, the electrode 230 includes a pin 231 that is electrically connected to the heating device 220. The pins are conductive metal, and are connected to the heating device 220 for transmitting electric energy. The pin 231 is tapered and can be electrically connected to the heating device 220 through an electrode hole of the flexible switch 100.

In some embodiments, the housing 210 includes an air passage, the flexible switch 100 corresponds to the position of the air passage and the diameter of the flexible valve is equal to or greater than the diameter of the air passage. The diameter of the flexible valve on the flexible switch 100 is larger than that of the air passage, so that the suction resistance of a user is reduced, and the user experience is improved.

Figure 3 is a schematic structural diagram of an electronic cigarette according to one embodiment of the invention. As shown, the electronic cigarette 300 includes a tobacco rod 310 and a cartridge 200. Wherein the cartridge 200 is removably mounted to the tobacco rod 310. When the cartridge 200 is assembled on the tobacco rod 310, the electrodes of the cartridge 200 contact metal contacts on the tobacco rod 310 so that the power source in the cartridge 200 can provide electrical power to the heating device for heating the tobacco tar to produce smoke. In some embodiments, the cartridge 200 is a disposable cartridge that can be replaced with a new cartridge after the tobacco tar is exhausted. In other embodiments, the cartridge 200 is a reusable cartridge that includes an oil inlet therein, which can be used to replenish the tobacco tar.

The above embodiments are provided only for illustrating the present invention and not for limiting the present invention, and those skilled in the art can make various changes and modifications without departing from the scope of the present invention, and therefore, all equivalent technical solutions should fall within the scope of the present invention.
