With reference to
The aforementioned cover component 200 is detachably connected with the injection end 104 and configured to open or close the injection port 107. When users dismantle the cover component 200, the users may add the tobacco liquid into the injection port 107 by using an injection container. The cover component 200 and the injection end 104 with corresponding snapping structures are clamped by snap joint, that is, after the cover component 200 is inserted into the injection end 104, the cover component 200 is rotated to a certain angle to be clamped with the injection end 104. Compared to the thread connection in the prior art, apart from the connection way of snap joint is simple to reduce the product cost, it only needs to rotate a certain angle to dismantle the cover component 200, the operation is quite easy.
More specifically, as one example of the snap joint structures, the injection end 104 has at least one protrusions 106, in some embodiments, there are two protrusions 106, inner wall of the cover component 200 has a undercut 203 along an axial direction thereof, and an curved undercut 204 along an circumferential direction thereof to match with insertion of the two protrusions 106. When the cover component 200 is connected with the shell component 100, the protrusion 106 inserts into the curved undercut 204 along the undercut 203 and is rotated to a certain angle to catch with the curved undercut 204. In some embodiments, the curved undercut 204 has a positioning structure configured to restrain the rotated angle of the injection end 104, such as to rotate the injection end 104 to 120 degree. On the contrary, to rotate the injection end 104 back to 120 degree may dismantle the injection end 104 from the cover component 200. The aforementioned positioning structure includes a pair of positioning columns 209 extending convexly from inner wall of the curved undercut 204 to stop the protrusion 106 to move.
With reference to
In some embodiments, the cover component 200 further includes an elastic element, when the cover component 200 is snapped with the injection end 104, the elastic element abuts against the injection end 104. The elastic element includes a spring 208 and a lap joint 207 abutting against the spring 208, when the cover component 200 is snapped with the injection end 104, the spring 208 is pressed so that the lap joint 207 driven by the spring 208 is lapped with the injection end 104, therefore, the rotational friction between the cover component 200 and the injection end 104 gets larger to prevent the cover component 200 from falling off because of faulty operations, so as to prevent leakage of the tobacco liquid.
