It should be appreciated that the shortest distance between the first stop and the second stop should be greater than or equal to the distance that the locking end 112 extends into the liquid storage component 13 in the first state of the liquid injection protecting device 10, so as to avoid that the locking end 112 still partially extends into the liquid storage component 13, and the locking end 112 cannot extend out of the liquid storage component 13 due to the limiting action of the first stop and the second stop, so that the liquid injection protecting device 10 cannot reach the second state. The first and second stoppers may be square or ring-shaped in shape, without limitation.

The connector 12 includes a connector body 122, a retainer 123, and an annular ring 124.

The connector body 122 is provided with a rotation shaft hole 1221, a first through hole 121, and a sliding slot 1222.

The first through hole 121 is centrally disposed within the connector body 122. The rotation shaft hole 1221 and the sliding slot 1222 are located at both sides or one side of the first through hole 121. Specifically, an included angle between the center of the rotation shaft hole 1221 and the first line of the center of the first through hole 121, the center of the sliding groove 1222, and the second line of the center of the first through hole 121 is greater than or equal to 0 ° and less than or equal to 180 °, and when the included angle between the first line and the second line is greater than or equal to 0 ° and less than or equal to 90 °, the rotation shaft hole 1221 and the sliding groove 1222 are located at one side of the first through hole 121; when the included angle between the first and second wires is greater than or equal to 90 ° and less than or equal to 180 °, the rotation shaft hole 1221 and the sliding groove 1222 are located at both sides of the first through hole 121. In this embodiment, the included angle between the first and second wires may be 30 °. In other embodiments, the included angle between the first connection line and the second connection line may be other values, for example, 15 °, 60 °, 90 ° or 120 °, etc., where the included angle between the first connection line and the second connection line is not limited, and may be selected according to practical situations in the present application.

The pivot hole 1221 and the slot 1222 may each be provided at a bottom of the connector body 122 facing the reservoir assembly 13.

In this embodiment, the spindle hole 1221 may include a first spindle hole 1223 and a second spindle hole 1224 located in the first spindle hole 1223 facing away from the reservoir assembly 13, the first spindle hole 1223 and the second spindle hole 1224 communicating, the first spindle hole 1223 having a smaller cross-sectional dimension than the second spindle hole 1224.

Alternatively, in other embodiments, the chute 1222 may include a first chute and a second chute located in the first chute opposite from the liquid storage assembly 13, where the first chute and the second chute are in communication, the first chute has a smaller cross-sectional dimension than the second chute, and the two chutes have inverted L-shaped cross-sections, and by providing the first chute and the second chute and the same inverted L-shaped slider, the axial movement of the liquid storage assembly 13 and the connector 12 can be further limited, so that the mechanism of the liquid injection protection device 10 is more compact and has better sealing effect.

The resisting member 123 has a resisting portion 1231 and a receiving portion 1232, the resisting portion 1231 is disposed at an end of the receiving portion 1232 and protrudes from the receiving portion 1232 in a ring shape, the receiving portion 1232 can extend into the first through hole 121, and the resisting portion 1231 can be fixed on a side surface of the connecting member main body 122 facing away from the operating end 111.

An annular ring 124 is partially looped over the connector body 122, the annular ring 124 being connected between the connector body 122 and the operating end 111 to provide a tight connection of the injection protector 10.

The top of the liquid storage component 13 facing the connecting piece 12 is provided with a liquid injection port 131 and a second through hole 132. The second through-hole 132 may be centrally disposed within the reservoir assembly 13. The cross-sectional dimension of the second through hole 132 should be greater than or equal to the cross-sectional dimension of the locking end 112 so that the locking end 112 can partially extend into the second through hole 132.

The fill port 131 may be a circular or non-circular orifice, and preferably a non-circular orifice, to avoid the formation of a film at the fill port by surface tension of the liquid during fill. Alternatively, the injection port 131 may be a polygonal hole, an elliptical hole, or a hole of another combination shape. In this embodiment, the liquid injection port 131 is a racetrack hole (which is substantially composed of two parallel straight lines or curves and two semicircular ends), and the shape of the liquid injection port 131 is not limited in this embodiment, so long as the liquid injection port 131 can inject liquid.

A first seal 133 is also provided between the reservoir assembly 13 and the connector 12, the first seal 133 being located within the top of the reservoir assembly 13, and the first seal 133 being used to form a seal between the reservoir assembly 13 and the connector 12. In this embodiment, a first sealing member 133 in the form of a sealing ring is disposed around the liquid injection port 131. The first sealing member 133 may be a silicone member or other member having a sealing effect. In this embodiment, the first seal 133 may further be provided with an annular protrusion 1331, and the annular protrusion 1331 may prevent smoke liquid from leaking out during liquid injection and may form a seal better.

The liquid storage assembly 13 is provided with a rotating shaft 134 and a sliding block 135. The rotating shaft 134 may be disposed corresponding to the rotating shaft hole 1221, the sliding block 135 is disposed corresponding to the sliding groove 1222, and the rotating shaft 134 and the sliding block 135 are disposed on the top of the liquid storage assembly 13 near the connecting member 12.

The rotating shaft 134 and the rotating shaft hole 1221 cooperate to form a structure of the rotating shaft 134 and the rotating shaft hole 1221, so that the connecting piece 12 is pivotally connected to the liquid storage component 13 by taking the rotating shaft 134 as a center, and the connecting piece 12 can be pivotally installed on the liquid storage component 13 through the structure of the rotating shaft 134 and the rotating shaft hole 1221. In addition, the structure of the spindle 134 and the spindle hole 1221 may include a first engaging structure for preventing the connecting member 12 from moving away from the liquid storage assembly 13. Specifically: the rotating shaft 134 includes a first rotating shaft 1341 and a second rotating shaft 1342 positioned on the first rotating shaft 1341 facing away from the liquid storage assembly 13, the first rotating shaft 1341 having a smaller cross-sectional dimension than the second rotating shaft 1342; the first shaft hole 1223 mates with the first shaft 1341 and the second shaft hole 1224 mates with the second shaft 1342. Thus, the movement of the connecting member 12 toward the side facing away from the liquid storage assembly 13 can be restricted by the restriction of the lower surface of the second rotary shaft 1342 to the upper surface of the first rotary shaft hole 1223.

To facilitate the installation of the shaft 134, the connecting member 12 and the liquid storage assembly 13, the liquid storage assembly 13 may further be provided with an opening 136, and the shaft 134 is matched with the opening 136 at the top of the liquid storage assembly 13 through a shaft hole 1221, specifically, the first shaft 1341 passes through the connecting member 12 and is tightly matched with the opening 136. The first shaft 1341 may be fixedly coupled to the opening 136 by threaded engagement, welding, adhesive, etc.; the first shaft 1341 and the opening 136 may be movably coupled so long as the shaft 134 is allowed to pivot relative to the opening 136 but is not allowed to move in an axial direction.

A slider 135 may be provided on top of the reservoir assembly 13 near the connector 12. The slider 135 and the slot 1222 cooperate to form a structure of the slider 135 and the slot 1222, which limits the pivotal travel of the connector 12. Specifically, when the injection molding apparatus 10 is in the first state, the slider 135 is at a first end of the chute 1222, and when the injection molding apparatus 10 is in the second state, the slider 135 is at a second end of the chute 1222 opposite the first end.

In other embodiments, the structure of the slider 135 and the sliding slot 1222 may further include a second engagement structure for preventing the connector 12 from moving away from the reservoir assembly 13. For example, the slider 135 may include a first slider and a second slider located on a side of the first slider facing away from the liquid storage component 13, where the first slider and the second slider are connected, the cross-sectional dimension of the first slider is smaller than that of the second slider, the first sliding groove and the first slider are matched to form an inverted L-shaped profile, and the second sliding groove and the second slider are matched to further limit the movement of the connecting member 12 toward a side facing away from the liquid storage component 13, so that the mechanism of the liquid injection protection device 10 is more compact and has better sealing effect.

Alternatively, the cross-sectional shape of the slider 135 may be circular, elliptical, polygonal, or other combined shape, and the sliding cross-sectional shape is not limited in this embodiment, as long as limitation of the pivoting stroke of the link 22 can be achieved.

The pressing member is used to apply a force to the locking piece 11 towards the reservoir assembly 13, thereby pressing the locking piece 11 against the connecting piece 12 or pressing the connecting piece 12 against the reservoir assembly 13 by the locking piece 11.

The pressing member may be an elastic member.

In this embodiment, the pressing member may be a coil spring 14. The first end of the coil spring 14 may be fixedly coupled to the operating end 111 of the locking member 11, and the second end of the coil spring 14 may be fixedly coupled to the abutment 123.

When the priming prevention device 10 is in the first state, the coil spring 14 is in the first extended state, and the coil spring 14 can apply a force to the lock holder 11 toward the reservoir assembly 13 due to the coil spring 14 being in the extended state. When the priming protection 10 is in the second state, the coil spring 14 is in the second extended state, and the operating end 111 no longer abuts the connecting piece 12 because the abutment 1231 of the abutment 123 abuts the connecting piece body 122, and therefore the lock holder 11 no longer has a force applied towards the reservoir assembly 13. It should be appreciated that the length of the coil spring 14 in the second elongated state should be greater than the length of the coil spring 14 in the first elongated state, and the difference between the length of the coil spring 14 in the second elongated state and the length of the coil spring 14 in the first elongated state should be greater than or equal to the length of the locking end 112 extending into the second through hole 132.

Of course, the retaining member 123 may be fixed to the locking end 112 only, and both ends of the coil spring 14 may be fixedly or movably held between the annular ring 124 and the retaining portion 1231 in a compressed state. In this case, the coil spring 14 can apply a force to the lock holder 11 toward the reservoir assembly 13.

The pressing member may be an elastic member such as an elastic piece, an elastic strip, or an elastic rubber, as long as it can exert a force toward the reservoir assembly 13 on the lock holder 11.

In another embodiment, such as the second embodiment described below, the pressure applicator member may be a first thread disposed at the locking end 112 and a second thread disposed at the second through hole 132; when the first thread is screwed with the second thread, the locking member 11 presses the connecting member 12 against the liquid storage assembly 13. In yet another embodiment, such as the third embodiment described below, the pressing member may be a snap structure provided on the locking end 112 of the locking piece 11 and the first through hole 121/the second through hole 132, and the locking piece 11 is pressed against the connecting piece 12 when the snap structure is engaged. For details, refer to the following description.

When force is applied to the locking piece 11 only by the pressing member, the locking piece 11 is pressed on the connecting piece 12 or the locking piece 11 presses the connecting piece 12 on the liquid storage assembly 13, and the locking end 112 is partially inserted into the second through hole 132 of the liquid storage assembly 13, at this time, the connecting piece 12 cannot pivot relative to the liquid storage assembly 13 and the liquid injection port 131 is blocked by the connecting piece 12; when the operating end 111 of the locking member 11 is operated such that the locking member 11 overcomes the force of the pressing member, the locking end 112 of the locking member 11 is no longer located in the second through hole 132 of the reservoir assembly 13, and the connecting member 12 is now able to pivot together with the locking member 11 relative to the reservoir assembly 13 in a plane parallel to the top of the reservoir assembly 13 to expose the filling port 131.

In this embodiment, the liquid storage assembly 13 further includes a liquid storage chamber 137 in communication with the liquid injection port 131, and the liquid storage chamber 137 is used for storing liquid.

The working principle of the liquid injection protecting device 10 of the present embodiment is described below: when the injection protection device 10 is in the first state, the coil spring 14 is in the first extension state, the coil spring 14 can apply a force to the locking piece 11 towards the liquid storage component 13, so that the locking piece 11 can be pressed on the connecting piece 12 or the locking piece 11 presses the connecting piece 12 on the liquid storage component 13, the locking end 112 is partially inserted into the second through hole 132 of the liquid storage component 13, the sliding block 135 is positioned at the first end of the sliding groove 1222, the locking end 112 of the locking piece 11 is partially inserted into the second through hole 132 of the liquid storage component 13, the liquid storage component 13 has a limiting effect on the locking piece 11, and therefore the connecting piece 12 sleeved on the locking end 112 cannot pivot relative to the liquid storage component 13 and the injection port 131 is blocked by the connecting piece 12; when a user needs to inject the tobacco juice into the tobacco juice accommodating cavity 137, the user can operate the operating end 111 of the locking member 11, so that the operating end 111 moves towards the side away from the liquid storage component 13, specifically pulls the operating end 111 until the locking end 112 of the locking member 11 is no longer located in the second through hole 132 of the liquid storage component 13, at this time, the coil spring 14 is in the second extension state, at this time, the liquid storage component 13 no longer has a limiting effect on the locking member 11, and the user can rotate the connecting member 12, so that the connecting member 12 can pivot together with the locking member 11 relative to the liquid storage component 13 in a plane parallel to the top of the liquid storage component 13 to expose the liquid injection opening 131 until the sliding block 135 is located at the second end of the sliding groove 1222, at this time, the liquid injection protecting device 10 is in the second state.

In addition, when the smoke liquid is added, the user can rotate the connecting piece 12 back to the original position, and the locking end 112 is directly extended into the liquid storage component 13 through the rebound action of the coil spring 14, and at this time, the liquid injection protection device 10 returns to the first state.

In this way, when a user needs to inject the tobacco liquid through the liquid injection port, the user only needs to pull the operation end, and the connecting piece can pivot in a plane parallel to the top of the liquid storage assembly with the locking piece by rotating the connecting piece, so that the liquid injection port is exposed. In the process of switching the first state and the second state, the connecting piece is always sleeved on the locking end of the locking piece, so that the embodiment can enable a user to inject tobacco liquid into the tobacco liquid accommodating cavity without detaching the locking piece, and the pressing component in the embodiment is a spiral spring, so that the user can operate the operating end easily, and the locking end of the locking piece can extend out of the second through hole easily.
