[ detailed description ] embodiments

To facilitate an understanding of the invention, the invention will now be described more fully with reference to the accompanying drawings.

The liquid injection device of the invention can be used for injecting any liquid. However, in the described embodiment of the invention, the electronic cigarette is mainly used for filling the electronic cigarette with the cigarette liquid.

Referring to FIG. 1, a priming device 11 of one embodiment includes a reservoir for vials 22 and a syringe 21. The bottle body 22 is mainly used for containing tobacco juice, and the tobacco juice can be filled into the electronic cigarette for multiple times through the liquid filling device, or the tobacco juice can be filled into the electronic cigarette when the electronic cigarette is used for the first time.

In one embodiment, the bottle body 22 is made of plastic or elastic material, and the electronic cigarette is filled by pressing the bottle body 22 to guide the smoke liquid in the bottle body 22 out from the filling device 21. The bottle body 22 made of elastic or plastic material can be used to squeeze the cigarette liquid in the bottle body 22 out through the liquid injection device by squeezing the bottle body 22 by hand when the cigarette liquid is injected.

The bottle body 22 includes a bottle body 222 and a bottle mouth 221 integrally formed with the bottle body 222, the bottle body 222 is used for containing tobacco juice, and the bottle mouth 221 is used for fitting the liquid injection device 21. When the tobacco liquid is filled, the plastic or elastic bottle body 222 is mainly extruded, so that the tobacco liquid in the bottle body 22 is guided out through the liquid injection device 21 after being extruded. The length of the bottle opening 221 is consistent with the fixed height of the liquid injection device, so that the liquid can be injected when the amount of the liquid in the bottle body 222 is small, and the liquid can be injected as far as possible when the amount of the liquid in the bottle body is minimum. In this embodiment, the bottle opening 221 is a hollow cylinder with a certain length, and in other embodiments, the bottle opening may have a normal length.

The syringe 21 is fixedly connected to the mouth 221 of the vial 22. The body 222 is squeezed to guide the smoke in the bottle 22 out through the syringe 21, wherein a portion of the injector 21 is accommodated in the mouth 221, and another portion of the injector extends out from the mouth 221.

As shown in fig. 2 to 8, the injector 21 includes a liquid injection needle 110 and an elastic device, the liquid injection needle 110 is provided with a conduit 111, the elastic device is fixedly and hermetically connected with the bottle opening 221, the liquid injection needle 110 is provided on the elastic device, and the conduit 111 of the liquid injection needle 110 can make a smoke liquid circulation pipeline between the inside of the bottle body 22 and the outside under the action of external force and the elastic device to be in a conduction state or a disconnection state, so as to realize the flow guiding or the disconnection of smoke liquid in the bottle body 22. If a pressure is applied to the liquid injection needle 110, the liquid injection needle 111 retracts into the bottle body 22, the conduction tube 111 is conducted, and the tobacco juice in the bottle body 22 is guided out of the liquid injection needle 110 through the conduction tube 111 to the outside of the bottle body 22; if the external pressure is removed, the liquid injection needle 110 is restored to the initial state by the elastic restoring force of the liquid injection needle 110 under the action of the elastic device, and at this time, the conduction tube 111 and the bottle body 22 are in a closed state, so that the smoke liquid in the bottle body 22 cannot be guided out of the liquid injection needle 110 through the conduction tube 111 to the outside of the bottle body 22. Therefore, when the cigarette liquid is filled, the cigarette liquid in the bottle body can be guided out; after the use, ensure that the tobacco juice in the bottle body 22 does not flow out or leak out to reach and turn off the switching-on pipeline, promote sealed effect.

The elastic device comprises a top cover 120, a liquid injection bottom cover 17 and an elastic component 16, wherein one of the top cover 120 or the liquid injection bottom cover 17 is a columnar structure with an inner cavity; in this embodiment, the top cover 120 is a cylindrical structure with an inner cavity; wherein, the top cover 120 is fixedly connected with the bottle opening part 221 in a sealing way, and after the liquid injection bottom cover 17 is fixedly connected with the top cover 120 in a sealing way, a liquid injection cavity 223 is formed between the liquid injection bottom cover 17 and the columnar inner cavity of the top cover 120. The liquid injection bottom cover 17 is provided with a liquid extruding hole 171 which is communicated with the liquid injection cavity 223, so that the smoke liquid in the bottle body 22 can flow into the liquid injection cavity 223 through the liquid extruding hole 171.

The elastic member 16 is elastically compressed in the liquid storage chamber 223. in the present invention, the elastic member 16 may be a coil spring, a tower spring, or an elastic member having another configuration. In the present embodiment, the elastic member 16 is preferably a coil spring.

When the syringe is installed, one end of the needle 110 is exposed through the cap 120, and the other end is in abutting contact with the elastic member 16. Further, in order to make the injection needle 110 form an effective and stable abutment with the elastic component 16; at this time, a resisting portion 112 protruding outward along the liquid injection needle 110 may be disposed on an outer wall of the resisting end of the liquid injection needle 110, and an oil guiding hole 113 communicating with the resisting portion 112 is disposed at a contact position of the liquid injection needle 110 and the top cover 120, as shown in fig. 9; the stopping portion 112 can elastically return and abut against the elastic member 16.

When liquid injection is carried out, the pressurized liquid injection needle 110 retracts into the liquid injection cavity 223, at the moment, the oil guide hole 113 of the liquid injection needle 110 is separated from the sealing contact of the inner wall of the top cover 120, the conduction pipe 111 forms liquid path conduction with the liquid injection cavity 223 through the oil guide hole 113, and smoke liquid in the liquid injection cavity 223 is guided out; when the pressure is removed, the injection needle 110 returns to the initial state under the action of the elastic restoring force of the elastic component 16, and the oil guide hole 113 on the injection needle 110 is in sealing contact with the wall of the top cover 120, so that the conduction pipe 111 is closed, and the smoke liquid in the injection cavity 223 is prevented from being further guided out.

In another embodiment, as shown in fig. 2 to 8, the elastic device further comprises a liquid guiding member 15, the liquid guiding member 15 is disposed in the liquid injection cavity 223 and is in abutting contact with the elastic member 16, and the liquid injection needle 110 is disposed on the liquid guiding member 15 and makes the liquid injection cavity 223 form a conducting state or a non-conducting state with the outside through the liquid guiding member 15. Therefore, in use, the tobacco juice in the bottle body 22 flows out through the liquid injection bottom cover 17, the liquid injection cavity 223, the liquid guide 15 and the liquid injection needle 110 in sequence, and is finally injected into the electronic cigarette. It will be appreciated that in order to achieve priming when in use and no leakage when not in use, the smoke flow path from the priming bottom cap 17 to the liquid guide 15 is either open or closed as shown in figure 8. Specifically, an external force toward the liquid injection bottom cover 17 is directly applied to the liquid injection needle 110, the liquid injection needle 110 is driven by the external force to elastically retract toward the liquid injection bottom cover 17, so that the liquid guide member 15 elastically retracts toward the liquid injection bottom cover 17 by the movement of the liquid injection needle 110, thereby conducting the smoke liquid circulation pipeline, guiding smoke liquid out through the liquid injection bottom cover 17, the liquid injection cavity 223, the liquid guide member 15 and the liquid injection needle 110, and after the external force is removed, the liquid guide member 15 reversely moves by the elastic recovery of the elastic member 16 under the action of the elastic recovery force while the liquid injection needle 110 reversely moves, that is, the liquid guide member 15 and the liquid injection needle 110 return to the initial positions, thereby shutting off the smoke liquid circulation pipeline, mainly shutting off the smoke liquid circulation pipeline in the liquid guide member 15.

As shown in fig. 4 and 5, the liquid guide 15 includes a liquid guide portion 155 and a barrier portion 153 of a columnar structure. Wherein, the liquid guiding part 155 is provided with a liquid guiding inner tube 151, the liquid injection needle 110 is hermetically inserted into the liquid guiding inner tube 151, and the liquid guiding inner tube 151 and the conduction tube 111 of the liquid injection needle 110 form a smoke liquid pipeline to be communicated; a liquid inlet 152 communicated with the liquid guiding inner tube 151 is arranged on the side wall of the liquid guiding part 151. The blocking portion 153 may be a disk structure, or may be a blocking block or other blocking structure provided on the liquid guide portion 155. In this embodiment, the structure is a disk. The liquid guide part 15 may be exposed through the top cover 120 or may not pass through the top cover 120; if the liquid guiding part 15 can be exposed through the top cover 120, the liquid guiding part 15 can be effectively fixed.

The blocking portion 153 and the liquid guide portion 155 may be integrally formed or may be assembled after being separately formed.

The elastic member 16 is located between the stopper 153 and the liquid injection bottom cap 17. It can be understood that, as shown in fig. 8, one end of the elastic member 16 is in contact with the liquid injection bottom cover 17, the other end is in contact with the stopper 153, and the elastic member 16 is always in an elastically compressed state.

As shown in fig. 7, when the electronic cigarette needs to be filled with liquid smoke, an external force is applied to move the liquid injection needle 110 into the bottle body 22, at this time, the blocking portion 153 moves towards the liquid injection bottom cover 17 to further elastically compress the elastic member 16, after the blocking portion 153 moves towards the liquid injection bottom cover 17, a gap state occurs between the blocking portion 153 and the inner bottom surface of the top cover 120, at this time, the liquid inlet 152 on the liquid guide 15 is in communication with the liquid injection cavity 223, so that the liquid smoke flows from the bottom cover 17 to the liquid guide 155 through the liquid injection cavity 223 and is guided out through the conducting pipe 111 on the liquid injection needle 110. And after the liquid injection is finished, removing external force, then driving the blocking part 153 to move away from the liquid injection bottom cover 17 through the elastic part 16 by virtue of elastic restoring force, and enabling the liquid port 152 on the liquid guide part 15 to be closed by the inner wall of the top cover 120 so as to close the smoke liquid circulation pipeline and prevent smoke liquid from being guided or leaking out.

As shown in fig. 4, the liquid guiding member 15 further includes a first seal ring 18. The first sealing ring 18 is sleeved between the upper blocking part 153 of the liquid guide part 155 and the inner wall of the top cover 120, and the outer surface of the first sealing ring 18 is tightly attached to the inner wall of the top cover 120 to form a sealing gap-free structure.

As shown in fig. 5, the elastic member 16 is a coil spring fitted over the liquid guide 15, and the liquid guide 15 further includes a connecting portion 154 for mounting the coil spring. The connecting part 154 and the liquid guiding part 155 are respectively positioned at two sides of 153 of the blocking part, and the connecting part 154 is inserted into the hollow of the coil spring to stabilize or position the coil spring; the connecting portion 154 may also be inserted into a central hole of the injection bottom cap 17 to position and fix the liquid guiding member 15.

In the embodiment shown in fig. 6, a plurality of liquid squeezing holes 171 are formed, and a fixing hole 172 is formed at the bottom center position of the cup body, and the shape of the fixing hole 172 is matched with the connecting portion 154 of the liquid guiding member 15, so that when the liquid guiding member 15 compresses the coil spring to move, the connecting portion 154 can move towards the inside of the bottle body 22 through the fixing hole 172, and is used for positioning the liquid guiding member 15 to prevent the liquid guiding member 15 from deviating from the axial direction when moving towards the inside of the bottle to damage the whole liquid filling device.

As shown in fig. 4, the top cover 120 is provided with a mounting hole 130, the injection device 11 further includes a fixing head 10 provided with a fixing hole 101, the injection needle 110 is connected with the fixing head 10 in a penetrating manner through the fixing hole 101, the fixing head 10 is inserted into the mounting hole 130 of the top cover 120, and the fixing head 10 and the top cover 120 are sleeved in a relative axial movement manner. When the fixing head 10 is used for filling the electronic cigarette with the tobacco juice, the fixing head is used as a blocking part to block the tobacco juice cavity shell of the electronic cigarette and enable the liquid filling needle 110 to retract towards the bottle body 22, so that a tobacco juice conducting channel is formed among the inner cavity of the bottle body 22, the liquid cavity 223, the liquid guiding part 155 of the liquid guiding part 15 and the liquid filling needle 110, and the tobacco juice is guided out and is successfully filled.

The second sealing ring 14 is sleeved on the outer surface of the fixing head 10, and the second sealing ring 14 is positioned between the liquid guide member 15 and the top cover 120, so that the sealing effect is further enhanced. In order to further seal the vial 22 and the injector 21, a third gasket 13 is provided on the outer wall of the top cap 120, and the third gasket 13 may be provided between the top cap 120 and the vial mouth 221 in a plurality of parallel rows.

In one embodiment, as shown in fig. 10, to facilitate the installation of the filling device with the mouth portion 221 of the bottle 22, the inner surface of the mouth portion 221 is configured as a bevel structure or a wedge structure 224 with a larger top and a smaller bottom, and accordingly, the outer surface of the connection portion between the cap 120 and the mouth portion 221 in the filling device is configured as a bevel structure or a wedge structure, and the cap 120 is similar to a bottle stopper. This configuration advantageously allows the cap 120 to be sealingly and stoppered to the finish portion 221 of the vial 22. For further sealing, the top cover 120 may be made of food grade silicone rubber.

Further, when the bottle body 22 is squeezed to fill the tobacco solution, in order to prevent the cap 120 with the inclined surface structure from being released from the bottle opening 221 due to the internal stress generated by the squeezing of the bottle body 22, a bottle cap 121 is further added in the present embodiment, as shown in fig. 10; the liquid injection needle 110 of the liquid injection device penetrates through a through hole on the bottle cap, and the bottle cap 121 supports the top cover 120 to cover and form threaded fastening connection with the outer wall of the bottle mouth part 221; the cap 120 can be screwed to form a better seal with the mouth 221.

Referring to fig. 7 and 8, in use, the liquid injection needle 110 is inserted into a liquid chamber (not shown) of the electronic cigarette, and the bottle 22 is pressed vertically along the axial direction of the liquid injection needle 110, so that the elastic member 16 is further pressed. At the same time, the bottle body 22 is squeezed with force, and the tobacco juice in the bottle body 22 flows into the inner cavity of the top cover 120 through the liquid squeezing hole 171 of the liquid filling bottom cover 17. At this time, the blocking portion 153 of the liquid guiding member 15 and the bottom surface of the top cover 120 form a relief shape (i.e. non-sealing shape), and the smoke liquid flows into the liquid injection needle 110 through the gap via the liquid inlet 152 on the liquid guiding member 15 and through the liquid guiding inner tube 151, and finally is injected into the liquid cavity of the electronic cigarette. After the liquid injection is completed, the pressing of the bottle 22 is released, and at this time, the liquid guide 15 drives the blocking portion 153 to move to form a sealing contact with the bottom surface of the top cover 120 under the elastic restoring force of the elastic component 16, so as to close the conduction.

The liquid injection device pushes the liquid injection needle 110 to compress the elastic component 16 by external force to realize the conduction of the liquid injection channel, and then the bottle body 22 is extruded to start the liquid injection. When the external force disappears, the liquid injection needle 110 resets under the action of the elastic component 16, and meanwhile, the liquid injection channel is switched on and automatically closed, so that the smoke liquid does not flow out any more, and a good liquid sealing effect is realized.
