[0041] Embodiment 1

[0042] In view of the technical defects in the related art, the present embodiment provides an electronic cigarette. As shown in Figures 1 to 3 The electronic cigarette of the present embodiment includes a tobacco rod 300, and a cartridge 100 and an oil storage bottle 200 used in cooperation with the tobacco rod 300.

[0043] In combination with Figure 4 and Figure 5As shown, the cigarette rod 300 has a connecting groove 301 connected with the cartridge 100 and a connecting port 302 connected with the oil storage bottle 200. The cartridge 100 is internally formed with an atomizing cavity 101, and an atomizing core 140 for atomizing the tobacco tar is arranged in the atomizing cavity 101. The cartridge 100 is provided with a connecting channel 102 communicating with the atomizing cavity 101, and the cartridge 100 is inserted and matched with the cigarette rod 300 through the connecting groove 301. The oil storage bottle 200 is used for containing the tobacco tar, and the oil storage bottle 200 is inserted and matched with the cigarette rod 300 through the connecting port 302. In order to prevent the oil storage bottle 200 from being separated from the cigarette rod 300, the connecting port 302 can be opened and closed by a detachable sliding cover 303.

[0044] In combination Figure 1 and Figure 2 As shown, the electronic cigarette of the embodiment further comprises an oil filling pipe 400, an oil path valve 500 and a control knob 600. The oil filling pipe 400 is arranged in the cigarette rod 300, one end of the oil filling pipe 400 protrudes from the bottom of the connecting groove 301, the other end of the oil filling pipe 400 faces the connecting port 302, the oil path valve 500 is connected with the oil filling pipe 400 for opening and closing the oil filling pipe 400. The control knob 600 is arranged on the outer wall of the cigarette rod 300 and is in transmission connection with the oil path valve 500. Exemplarily, the transmission connection relationship between the control knob 600 and the oil path valve 500 can be formed by transmission components such as gears and screws, or the control knob 600 and the oil path valve 500 are integrally formed to form the transmission connection relationship, but are not limited thereto.

[0045] In combination Figure 7 As shown, the oil filling pipe 400 of the embodiment is formed with a mounting groove 410 communicating with the lumen of the oil filling pipe 400, and the oil path valve 500 is arranged in the mounting groove 410. The oil path valve 500 has a valve channel 510, and the oil path valve 500 is relatively movable with the mounting groove 410 under the driving of the control knob 600, so as to make the valve channel 510 and the lumen of the oil filling pipe 400 mutually communicate or mutually dislocate, thereby opening and closing the oil filling pipe 400. Exemplarily, according to the actual design purpose, the oil path valve 500 can be relatively rotated with the mounting groove 410 under the driving of the control knob 600, or the part of the oil path valve 500 provided with the valve channel 510 is separated from or embedded in the mounting groove 410 under the driving of the control knob 600, so as to realize the mutual communication or mutual dislocation between the valve channel 510 and the lumen of the oil filling pipe 400.

[0046] In the embodiment, during the process of connecting the cartridge 100 to the connecting groove 301, one end of the oil injection pipe 400 is inserted into the connecting channel 102, and the oil storage bottle 200 is communicated with the other end of the oil injection pipe 400 through the connecting port 302. Thus, after the cartridge 100 and the oil storage bottle 200 are connected to the cigarette rod 300 respectively, they are communicated with each other through the oil injection pipe 400. When the electronic cigarette of the embodiment is used, the whole electronic cigarette is inclined, the tobacco tar in the oil storage bottle 200 flows into the cartridge 100 under the action of gravity, and is converted into aerosol that can be smoked under the atomization of the atomization core 140. When the electronic cigarette of the embodiment is not used, the oil injection pipe 400 is closed by the control knob 600, so as to prevent the tobacco tar from being injected into the cartridge 100, thereby preventing the problem that the atomization core 140 is soaked by excessive tobacco tar for a long time when the electronic cigarette is left in the inclined state.

[0047] With reference to Figure 2 and Figure 3 continuously, the cartridge 100 comprises a shell 110 and a mouthpiece 120 connected to the shell 110. An open side of the shell 110 is formed in an open state, and the cartridge 100 further comprises a sealing cover 130 sealing the open side. The shell 110 and the sealing cover 130 enclose to form an atomization cavity 101, and one end of the atomization core 140 is communicated with the mouthpiece 120, so that the user can inhale the aerosol generated by the atomization core 140 when sucking the mouthpiece 120.

[0048] With reference to Figure 6 continuously, the connecting channel 102 is arranged in the sealing cover 130, and the oil stop valve 150 is arranged in the connecting channel 102. The oil stop valve 150 can be made of flexible materials such as silica gel. During the process of inserting one end of the oil injection pipe 400 into the connecting channel 102, the oil stop valve 150 is pushed away, and is communicated with the atomization cavity 101. When the cartridge 100 is separated from the cigarette rod 300, one end of the oil injection pipe 400 is separated from the connecting channel 102, so that the oil stop valve 150 returns to the initial state and blocks the connecting channel 102, thereby slowing down the process of the tobacco tar in the cartridge 100 leaking outwards through the connecting channel 102.

[0049] Optionally, as shown in Figure 2 and Figure 3 , the sealing cover 130 comprises a bottom cover 131 and an upper cover 132. The bottom cover 131 is embedded in the open side, and the upper cover 132 is arranged on the side of the bottom cover 131 facing the mouthpiece 120. The bottom cover 131 is provided with a first through hole, and the upper cover 132 is provided with a second through hole. The first through hole and the second through hole are communicated with each other to form the connecting channel 102. According to the actual design needs, the oil stop valve 150 can be arranged in the first through hole or the second through hole.

[0050] Embodiment 2

[0051] The technical scheme of the embodiment is an improved scheme based on embodiment 1.

[0052] As Figure 2 and Figure 3 and Figure 5 As shown in

[0053] Embodiment 3

[0054] The technical solution of the present embodiment is another improvement based on Embodiment 1.

[0055] As shown in Figure 8 The oil passage valve 500 is cylindrical, and the installation groove 410 is a contoured groove corresponding to the oil passage valve 500. The oil passage valve 500 has a valve passage 510 formed along a radial direction of the oil passage valve 500. Under the drive of the control knob 600, the oil passage valve 500 rotates relative to the installation groove 410, so that the valve passage 510 and the lumen of the oil injection pipe 400 are in communication or misaligned with each other. The lumen of the oil injection pipe 400 includes a first oil channel 401, a second oil channel 402, and a third oil channel 403. As shown in Figure 8 The first oil channel 401 is opened at one end of the oil injection pipe 400 and in communication with the installation groove 410, and the second oil channel 402 and the third oil channel 403 are respectively opened at the other end of the oil injection pipe 400 and in communication with the installation groove 410.

[0056] Continuing to refer to Figure 8 The valve passage 510 includes a first passage 511 formed along one radial direction of the oil passage valve 500 and a second passage 512 formed along another radial direction of the oil passage valve 500. It can be understood that in the present embodiment, the relative positional relationship between the first passage 511 and the second passage 512 and the installation groove 410 is controlled by rotating the oil passage valve 500 through the control knob 600.

[0057] Since the forming direction of the first passage 511 and the forming direction of the second passage 512 are different from each other, when the first passage 511 is communicated with the lumen of the oil injection pipe 400, the two ports of the second passage 512 are blocked by the groove wall of the mounting groove 410, so that the second passage 512 cannot be communicated with the lumen of the oil injection pipe 400; on the contrary, when the second passage 512 is communicated with the lumen of the oil injection pipe 400, the two ports of the first passage 511 are blocked by the groove wall of the mounting groove 410, so that the first passage 511 cannot be communicated with the lumen of the oil injection pipe 400.

[0058] In the present embodiment, the first passage 511 is used for the communication between the second oil channel 402 and the first oil channel 401 (as shown in the left upper side step of Figure 8 In the present embodiment, the first passage 511 is used for the communication between the second oil channel 402 and the first oil channel 401 (as shown in the left upper side step of Figure 8 In the present embodiment, the first passage 511 is used for the communication between the second oil channel 402 and the first oil channel 401 (as shown in the left upper side step of Figure 8 In the present embodiment, the first passage 511 is used for the communication between the second oil channel 402 and the first oil channel 401 (as shown in the left upper side step of

[0059] Of course, the oil injection pipe 400 can be closed by controlling the knob 600 to dislocate the first passage 511 and the second passage 512 from the lumen of the oil injection pipe 400 (as shown in the left lower side step of Figure 8

[0060] In the present embodiment, the number of the oil storage bottles 200 is two, one of which is connected to the second oil channel 402, and the other of which is connected to the third oil channel 403. Exemplarily, the tobacco juice contained in one of the oil storage bottles 200 is grape flavored, and the tobacco juice contained in the other of the oil storage bottles 200 is lemon flavored.

[0061] When the second oil channel 402 and the first oil channel 401 and the third oil channel 403 and the first oil channel 401 are communicated through the first passage 511, the tobacco juice of the above two flavors flows into the cartridge 100 through the oil injection pipe 400, so that the user can experience the aerosol of the mixed flavor of grape and lemon.

[0062] When only the second oil channel 402 and the first oil channel 401 are communicated through the second passage 512, only the grape flavored tobacco juice flows into the cartridge 100 through the oil injection pipe 400, so that the user can experience the aerosol of the grape flavored tobacco juice.

[0063] When only the third oil channel 403 and the first oil channel 401 are communicated through the second passage 512, only the lemon flavored tobacco juice flows into the cartridge 100 through the oil injection pipe 400, so that the user can experience the aerosol of the lemon flavored tobacco juice.

[0064] ​It should be noted that the first channel 511 and the second channel 512 of the embodiment can be in communication with each other (as shown in Figure 8 ), or the first channel 511 and the second channel 512 are independent channels isolated from each other (as shown in Figure 9 ). It can be understood that when the first channel 511 and the second channel 512 are independent channels isolated from each other, the first oil passage 401, the second oil passage 402 and the third oil passage 403 respectively form a front projection on the oil way valve 500 should cover the ports of the first channel 511 and the second channel 512.

[0065] Embodiment 4

[0066] The technical solution of the embodiment is another improvement scheme based on embodiment 1.

[0067] As shown in Figure 10 , the oil way valve 500 is cylindrical, and the mounting groove 410 is a contoured groove corresponding to the oil way valve 500. The oil way valve 500 has a valve passage 510 formed along the radial direction of the oil way valve 500. The oil way valve 500 and the mounting groove 410 are relatively rotated under the drive of the control knob 600, so that the valve passage 510 and the lumen of the oil injection pipe 400 are in communication or misaligned with each other. Among them, the lumen of the oil injection pipe 400 includes the fourth oil passage 404, the fifth oil passage 405 and the sixth oil passage 406. As shown in Figure 10 , the fourth oil passage 404 is opened at one end of the oil injection pipe 400 and communicates with the mounting groove 410, and the fifth oil passage 405 and the sixth oil passage 406 are respectively opened at the other end of the oil injection pipe 400. The fifth oil passage 405 and the sixth oil passage 406 respectively communicate with the mounting groove 410.

[0068] In this embodiment, the control knob 600 has a first drive state, a second drive state and a third drive state. Exemplarily, the drive state of the control knob 600 can be determined by the relative positional relationship between the control knob 600 and the tobacco rod 300, for example: three pre-arranged clamping grooves are opened on the outer wall of the tobacco rod 300, and the control knob 600 has a buckle connected with one of the clamping grooves. The buckle is connected to different clamping grooves to determine the relative positional relationship between the control knob 600 and the tobacco rod 300, that is, the relative positional relationship between the valve passage 510 and the mounting groove 410 is controlled by rotating the oil way valve 500 by the control knob 600.

[0069] Among them, in the first drive state, the valve passage 510 communicates the fifth oil passage 405 and the fourth oil passage 404 (as shown in Figure 10 the upper right side of the step).

[0070] In the second drive state, the valve passage 510 communicates the sixth oil passage 406 and the fourth oil passage 404 (as shown in Figure 10 the lower right side of the step).

[0071] In the third driving state, the valve passage 510 communicates the fifth oil channel 405 and the sixth oil channel 406 with the fourth oil channel 404 respectively (as shown in the left upper side step of FIG. 6). Figure 10

[0072] Of course, the oil injection tube 400 can be closed by controlling the knob 600 to dislocate the valve passage 510 from the lumen of the oil injection tube 400 (as shown in the left lower side step of FIG. 6). Figure 10 Figure 10

[0073] In the present embodiment, the number of the oil storage bottles 200 is two, one of which is connected to the second oil channel 402 and the other of which is connected to the third oil channel 403. Exemplarily, the tobacco juice contained in one of the oil storage bottles 200 is grape flavored and the tobacco juice contained in the other of the oil storage bottles 200 is lemon flavored.

[0074] When the valve passage 510 communicates the fifth oil channel 405 and the sixth oil channel 406 with the fourth oil channel 404 respectively, the tobacco juice of the above two flavors flows into the cartridge 100 through the oil injection tube 400, so that the user can experience the aerosol of the mixed flavor of grape and lemon.

[0075] When the valve passage 510 communicates the fifth oil channel 405 and the fourth oil channel 404, only the grape flavored tobacco juice flows into the cartridge 100 through the oil injection tube 400, so that the user can experience the aerosol of the grape flavor.

[0076] When the valve passage 510 communicates the sixth oil channel 406 and the fourth oil channel 404, only the lemon flavored tobacco juice flows into the cartridge 100 through the oil injection tube 400, so that the user can experience the aerosol of the lemon flavor.

[0077] The above only describes some or preferred embodiments of the present application, neither the text nor the drawings can limit the scope of protection of the present application, any equivalent structural transformation based on the content of the present application and the drawings, or direct / indirect application in other related technical fields are included in the scope of protection of the present application.​​
