The connection part 432 is configured to be axially extended from the lower surface of the button part 431 to be inserted into the elastic member 42. The diameter h8 of the extension portion 432 is formed to be smaller than the inner diameter h9 of the body portion 41.

The contact part 433 is expanded and expanded at the end of the extension part 432 to close the bottom surface of the air inflow path 44 to be described later when the switch part 4 is inoperative, and the switch part 4 In the operation of the air inlet 44, the bottom surface of the opening and the configuration is in contact with one side of the conductor pin receiving portion (14). The connection part 432 and the contact part 433 may be connected by screwing as shown in FIG.

The air inflow path 44 is a space between the inner surface of the body part 41 and the outer surface of the operation part 43. The lower end surface of the air inflow path 44 So that air can be introduced into the inside of the housing (11). The operation principle of the switch unit 4 will be described in detail below.

Hereinafter, referring to FIGS. 1 to 14, the coupling relationship and operating principle of the electronic cigarette including the above configuration will be described.

First, referring to the method of coupling the electronic cigarette, the conductor pin 16 with the watertight film 181 inserted thereon is inserted into the second fixing part 17, and the second fixing part 17 is inserted into the conductor pin receiving part ( 14) to be screwed into the insert, the conductor pin receiving portion 14 is inserted into the first fixing portion 15 by screwing, and the first fixing portion 15 is inserted into the upper housing 111, the screw Combine. After the lower cover 12 is screwed into the lower housing 112, the battery 13 is inserted into the lower housing 112, and the upper housing 111 and the lower housing 112 are screwed to form a power supply 1. The lower solution receiving portion 212 is screwed on the upper housing 111, the smoke generating portion 3 is screwed on the upper side of the conductor pin receiving portion 14, and integral with the smoke discharge portion 22. The upper solution receiving portion 211 coupled to the lower solution receiving portion 212 is screwed, thereby coupling the power supply unit 1, the cartridge unit 2 and the smoke generating unit 3 with each other. Thereafter, the switch unit 4 is inserted into the switch coupling groove 111d of the upper housing 111 to finally form an electronic cigarette.

Next, referring to the operation principle of the electronic cigarette, the positive electrode of the battery 13 is in contact with the lower surface of the conductor pin 16 and the upper surface of the conductor pin 16 is in contact with the lower surface of the smoke generating unit 3 The lower side of the smoke generating unit 3 is connected to the conductor pin receiving portion 14. In addition, the (-) pole of the battery 13 is in contact with the lower cover 12, the lower cover 12 is connected to the housing 11 and the switch portion 4 on one side of the housing 11 Is connected. When the electronic cigarette is not in use, as shown in FIG. 11, the switch unit 4 is turned off without contacting the conductor pin receiving unit 14 to supply power to the smoke generating unit 3. It doesn't work.

When the user rotates and lowers the cartridge unit 2 in the combined electronic cigarette as shown in FIG. 11, the protruding jaw 212c in the cartridge is also lowered, opening the solution inlet passage S2 as shown in FIG. ) Can be introduced into the smoke generating unit (3) through the solution inlet hole (35).

After opening the solution inflow path (S2), pressing the button portion 431 of the switch portion 4 as shown in Figure 13 the contact portion 433 is in contact with the conductor pin receiving portion 14 and the power is connected Power is supplied to the smoke generator 3. In addition, when the button 431 of the switch unit 4 is pressed, not only the power is connected but also the contact unit 433 is spaced apart from the lower jaw 413 to open the groove 413a of the lower air inflow path 44. Since the bottom surface is opened, external air may be introduced into the housing 11 of the electronic cigarette through the air inflow path 44.

When the user operates the switch unit 4 to supply power and sucks the smoke discharge unit 22 into his or her mouth, the pressure in the smoke generating unit 3 is lowered so that the solution A is the solution inflow path (S2). ) And the solution inlet hole (35) in order to flow into the smoke generating unit (3) to be absorbed by the solution absorbing member (36) and the solution is vaporized by the heating member (37) to smoke, at the same time the external air The air inflow path 44, the first air inlet hole 143 of the conductor pin receiving portion 14, the air moving path (S1), the second air inlet hole 33 of the smoke generating unit 3 in order Passed through the smoke generating unit 3 is introduced into the user's mouth through the hollow 221 of the smoke discharge unit 22 together with the smoke generated by the smoke generating unit (3). Since the watertight membrane 181 is made of a material having flexibility and elasticity, the watertight membrane 181 is bent upward by air as shown in FIG. 14 in the process of introducing air, thereby opening the air movement path S1. do.

When the user no longer inhales the electronic cigarette, the pressure of the smoke generating unit 3 is increased so that no external air is introduced therein, and as shown in FIG. Close S1). In addition, when the operation of the switch unit 4 is stopped, that is, when the button 431 is released, the operation unit 43 moves upward. As shown in FIG. 12, the contact unit 433 is connected to the conductor pin receiving unit ( 14, the power is released from the space, and the upper surface of the contact portion 433 is in contact with the lower jaw 413 closes the groove 413a to close the lower surface of the air inlet passage 44 to the housing 11 Do not allow air to enter inside.

Thereafter, when the cartridge unit 2 is rotated and lifted from the housing 11, the protrusion jaw 212c in the cartridge unit 2 also rises, so that the upper surface of the protrusion jaw 212c as shown in FIG. The solution inflow path S2 is closed in contact with the lower surface of the upper portion 31 of the generation unit 3 so that the solution does not flow into the smoke generation unit 3.

The electronic cigarette is characterized by preventing the inflow of air and solution when not in use to maintain cleanliness and prevent failure. In addition, the electronic cigarette is characterized in that the convenience and ease of use and the number of parts can be reduced by opening and closing the air inflow path through which air is introduced at the same time as the connection and disconnection of the power supply, economical efficiency and miniaturization. . In addition, the electronic cigarette is characterized in that the watertight film to open the air moving path only when the air is introduced, when the electronic cigarette is not in use to prevent the solution flows into the battery, etc., the product can improve the performance.
