Description

Technical Field

[0001] The utility model relates to the technical field of electronic cigarettes, and in particular to an electronic cigarette with oil storage in separate warehouses. Background Art

[0002] At present, most of the electronic cigarettes on the market have the atomization chamber directly set in the oil storage chamber, and the oil is transferred to the heating core through the oil storage cotton, and the smoke generated by the heating core flows out from the airway. However, the oil in the oil storage chamber will also come into direct contact with the air through the airway, causing the aroma of the oil to evaporate, causing the oil to change its taste and reduce the shelf life. In addition, the oil storage cotton has a limited oil isolation effect, which makes this type of electronic cigarette structure prone to oil leakage under the influence of transportation, climate and temperature, and safety accidents such as short circuits of the smoking device. Summary of the invention

[0027] Reference Figure 1 、 Figure 2 and Figure 5 ,the present utility model provides a split-storage oil storage electronic cigarette 100, comprising: an oil cup 10, an oil valve 20 and an oil storage bottle 31. The oil cup 10 includes an atomization chamber 11, which is provided with an atomization component 16 for heating the e-liquid. The structure of the atomization component 16 can refer to the prior art and will not be elaborated here. The atomization chamber 11 is communicated with a mouthpiece 122, and the generated smoke is discharged from the mouthpiece 122. The atomization chamber 11 is also provided with a first opening 132 for inputting e-liquid. The oil storage bottle 31 is used for storing e-liquid. The oil storage bottle 31 has a second opening 311 for injecting e-liquid. The oil valve 20 is arranged between the oil cup 10 and the oil storage bottle 31 and can reciprocate between a first position and a second position. When the oil valve 20 is in the first position, the first opening 132 of the atomization chamber 11 is communicated with the second opening 311 of the oil storage bottle 31. At this time, the oil storage bottle 31 can be operated (such as inverted) so that the e-liquid therein flows to the atomization chamber 11 through the first opening 132. After the introduction is completed, only the oil valve 20 needs to be moved to the second position. At this time, the oil valve 20 can simultaneously close the first opening 132 and the second opening 311, thereby blocking the communication between the oil storage bottle 31 and the atomization chamber 11, which is convenient for injecting e-liquid. Preferably, the oil cup 10 is ultrasonically welded to avoid multiple materials contacting the e-liquid, which is more environmentally friendly.

[0028] By arranging the oil valve 20 between the oil cup 10 and the oil storage bottle 31 in the embodiment of the present utility model, split-storage of oil can be realized, so that the e-liquid bottle and the atomization chamber 11 are completely separated for storage, which is also convenient for the preservation and refueling of e-liquid. At the same time, by moving the oil valve, the flow rate of the e-liquid flowing from the oil storage bottle 31 into the atomization chamber 11 can be controlled; the operation is simple.

[0029] Specifically, the oil cup 10 of this embodiment generally has a cylindrical structure and has a first end face 13 axially downward. The axial direction in this embodiment refers to the axial direction of the electronic cigarette 100. The oil cup 10 defines a channel 12, the upper end of the axis of the channel 12 is the mouthpiece 122, and the lower end 121 of the axis of the channel 12 is used for inhaling air. Among them, the first opening 132 axially penetrates the first end face 13. The lower end 121 of the axis of the channel 12 protrudes from the first end face 13. When sucking on the mouthpiece 122, air enters from the lower end 121 of the axis of the channel 12, and the smoke in the atomization chamber 11 flows along the channel 12 to the mouthpiece 122 and is thus sucked. Preferably, the channel 12 is located in the middle of the oil cup 10. The first opening 132 is located at a non-central position of the first end face 13.

[0030] The electronic cigarette 100 further includes an axially extending housing 30, wherein the oil storage bottle 31 is disposed in the housing 30. The housing 30 has an annular second end surface 33, and the second end surface 33 is disposed opposite to the first end surface 13. The axial lower end 121 of the channel 12 passes through the second end surface 33 and enters the housing 30.

[0031] The oil valve 20 is roughly disc-shaped and is disposed between the second end surface 33 of the oil cup 10 and the second end surface 33 of the shell 30. Preferably, the outer diameters of the oil cup 10, the oil valve 20 and the shell 30 are consistent, so that the connection between the oil valve 20 and the shell 30 is smoothly transitioned, so that the overall appearance of the electronic cigarette 100 is more beautiful. The oil valve 20 can reciprocate around the central axis of the electronic cigarette 100. The oil valve 20 is provided with a third through hole 21 that penetrates along the axial direction. The third through hole 21 is located at a non-center position of the oil valve 20 and corresponds to the first opening 132 and the second opening 311 respectively. In the first position, the third through hole 21 is simultaneously connected to the first opening 132 and the second opening 311. In the second position, the third through hole 21 is staggered with the first opening 132 and the second opening 311, so that the conduction between the first opening 132 and the second opening 311 is blocked. In other embodiments, the oil valve 20 may not be disc-shaped, but may be fan-shaped or other shapes. It is sufficient as long as the third through hole 21 is connected to both the first opening 132 and the second opening 311 when the oil valve 20 is in the first position and the connection between the first opening 132 and the second opening 311 is blocked when the oil valve 20 is in the second position.

[0032] In this embodiment, the oil cup 10, the oil valve 20 and the oil bottle are arranged in sequence from top to bottom along the axial direction of the electronic cigarette 100. In other embodiments, the oil cup 10, the oil valve 20 and the oil bottle can be arranged in sequence from left to right, from right to left, or from inside to outside, and other connection structures can also be adopted, as long as the connection between the oil cup 10 and the oil bottle can be opened or blocked through the oil valve 20.

[0033] like Figure 3 As shown, the first opening 132 is directly opposite to the second opening 311, so that when the two are connected, the smoke oil can quickly flow from the second opening 311 to the first opening 132. It is understandable that in other embodiments, the first opening 132 can also be staggered with the second opening 311, and the oil valve 20 only needs to be provided with a guide channel that can guide the smoke oil from the second opening 311 to the first opening 132. However, this setting method will cause the smoke oil to remain in the oil valve 20 and reduce the flow efficiency of the smoke oil.

[0034] In this embodiment, the oil valve 20 can be movably connected to the oil cup 10. Figure 2 and Figure 5As shown, the oil valve 20 is provided with a fourth through hole 24 axially penetrating therethrough. The fourth through hole 24 is connected to the screw 15 for connecting the oil valve 20 to the oil cup 10. The size of the fourth through hole 24 is larger than the diameter of the screw 15, so that the screw 15 does not interfere with the movement of the oil valve 20. Preferably, the size of the fourth through hole 24 is consistent with the trajectory formed by the screw 15 on the oil valve 20 when the oil valve 20 moves from the first position to the second position. It can be understood that in other embodiments, the oil valve 20 can also be movably connected to the housing 30. Preferably, there are three screws 15, and correspondingly, there are also three fourth through holes 24 to strengthen the connection between the oil valve 20 and the oil cup 10. The three fourth through holes 24 and a third through hole 21 are arranged on the oil valve 20 at intervals.

[0035] Preferably, the atomization chamber 11 has a first sealing cover 14 covering the first opening 132. The first sealing cover 14 is provided with a first through hole 142 axially penetrating therethrough. The oil storage bottle 31 has a second sealing cover 32 covering the second opening 311. The second sealing cover 32 is provided with a second through hole 322 axially penetrating the second sealing cover 32. The first through hole 142 and the second through hole 322 can communicate with the third through hole 21 of the oil valve 20. Further preferably, when the oil valve 20 is in the first position, the first through hole 142, the second through hole 322 and the third through hole 21 of the oil valve 20 are pairwise aligned. The settings of the first sealing cover 14 and the second sealing cover 32 can further enhance the sealing effect of the atomization chamber 11 and the oil storage bottle 31, and can prevent liquid leakage caused by too large an opening.

[0036] With reference to Figure 4 and Figure 5 , further preferably, the first sealing cover 14 has a first boss 141 protruding outward from the first opening 132, that is, the first boss 141 protrudes toward the oil valve 20. The first through hole 142 is provided on the first boss 141. The second sealing cover 32 has a second boss 321 protruding outward from the second opening 311, that is, the second boss 321 protrudes toward the oil valve 20. The second through hole 322 is provided on the second boss 321. When the oil valve 20 is in the second position, the first boss 141 and the second boss 321 simultaneously block the third through hole 21, thereby blocking the communication between the first through hole 142 and the second through hole 322.

[0037] To further enhance the assembly sealing performance between the oil valve 20, the oil cup 10, and the oil storage bottle 31, the axial end faces of the oil valve 20 are respectively provided with a first groove 22 and a second groove 23 for accommodating the first boss 141 and the second boss 321. The first groove 22 and the second groove 23 communicate with the third through hole 21, and the first groove 22 and the second groove 23 are arranged such that they do not interfere with the reciprocating rotation of the oil valve 20. That is, when the oil valve 20 rotates, the first boss 141 and the second boss 321 always remain respectively within the first groove 22 and the second groove 23. In this embodiment, the first boss 141 is the same as the second boss 321, and the first groove 22 is the same as the second groove 23. Here, the first boss 141 and the first groove 22 are taken as examples for illustration. As Figures 4 to 5 shown, the first groove 22 is formed by the front, middle, and rear circular grooves with the same diameter intersecting front and back, and is generally arc-shaped as a whole. The third through hole 21 is located at the middle circular groove. The first boss 141 is formed by the intersection of two circular platforms with the same diameter. Among them, the first through hole 142 is located on one of the circular platforms. The dimensions of the circular platform and the circular groove are the same. When the oil valve 20 is in the first position, the first boss 141 can be located within the front and middle circular grooves, and the first through hole 142 is aligned with and conducts with the third through hole 21. When the oil valve 20 is in the second position, the first boss 141 is shifted to the middle and rear circular grooves, and the circular platform of the first boss 141 without the first through hole 142 blocks the third through hole 21, thereby causing the oil valve 20 to cut off the conduction between the first through hole 142 and the third through hole 21. The movement of the second boss 321 within the second groove 23 is the same as above and will not be elaborated here. Since both the first boss 141 and the second boss 321 are made of elastic materials, when the oil valve 20 rotates, the first boss 141 and the second boss 321 are prone to deformation within the first groove 22 and the second groove 23.

[0038] In this embodiment, the oil valve 20 is also provided with a fifth through hole 25 axially penetrating. At the same time, the second end face 33 is also provided with a sixth through hole 331 axially penetrating, so that the axial lower end 121 of the channel 12 passes through the fifth through hole. This ensures that air does not enter the atomization chamber 11 through the oil valve 20, thereby further guaranteeing the seal between the oil cup 10 and the oil valve 20.

[0039] The housing 30 defines an oil storage bottle 31, such that the oil storage bottle 31 can be concealedly installed within the housing 30. The oil storage bottle 31 can carry a large-capacity e-liquid of 10 to 20 ml. The second opening 311 of the oil storage bottle 31 is formed on the second end face 33. The second opening 311 is directly opposite to the first opening 132. A battery 34 and a circuit board 35 may also be provided within the housing 30. Preferably, the oil storage bottle 31 extends axially and has a semi-circular cross-section. That is, the outer wall of the oil storage bottle can at least enclose a part of the outer periphery of the battery. Thus, the oil storage bottle 31 and the battery 34 and the circuit board 35 are disposed opposite to each other, saving more space. The battery 34 can be installed within the housing 30 through the sixth through hole 331. Preferably, the outer periphery of the oil valve 20 is provided with anti-slip lines to increase the rotational friction force.

[0040] In other embodiments, the oil storage bottle 31 may also be separately provided from the housing 30.

[0041] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention under the inventive concept of the present invention, or any direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
