And the fixing groove 219 does not penetrate through the second surface 212, that is, after the cover 210 is mounted on the mounting opening 120 of the housing 100, the fixing groove 219 is not communicated with the liquid storage cavity 110, so that the risk of leakage of atomized liquid in the liquid storage cavity 110 from the fixing groove 219 can be prevented.

The connecting end 221 and the free end 222 are integrally formed to facilitate manufacturing. Alternatively, the connection end 221 and the free end 222 may be formed as separate structures, and at this time, the connection end 221 and the free end 222 may be connected together by welding, bonding, or the like.

Further, as shown in fig. 2 to 5, the mounting groove 213 has a first groove side wall 2131 disposed close to the fixing groove 219, a first limiting groove 2132 is disposed on the first groove side wall 2131, a first limiting portion 2211 is convexly disposed on the outer periphery of the connecting end 221, and the first limiting portion 2211 is adapted to the first limiting groove 2132 and is disposed corresponding to the first limiting groove 2132; the mounting groove 213 further has a second groove side wall 2133 disposed near the liquid filling hole 215, a second limiting groove 2134 is disposed on the second groove side wall 2133, a second limiting portion 2221 is disposed on the outer periphery of the free end 222 in a protruding manner, and the second limiting portion 2221 is adapted to the second limiting groove 2134 and is disposed corresponding to the second limiting groove 2134. When the free end 222 covers the liquid injection hole 215, the second limiting portion 2221 is in clearance fit in the second limiting groove 2133 and the free end 222 abuts against the second groove side wall 2133, so that when the free end 222 moves to a position capable of covering the liquid injection hole 215, the second groove side wall 2133 can form a barrier to the free end 222, thereby avoiding the free end 222 from deviating from the position of the liquid injection hole 215 due to overlarge travel when the free end 222 moves along the direction close to the liquid injection hole 215, and enabling the free end 222 to accurately reach the position of the liquid injection hole 215 and completely cover the liquid injection hole 215 in the process of moving along the direction close to the liquid injection hole 215. When the free end 222 moves to a position capable of covering the liquid filling hole 215, the free end 222 of the connector 220 can be axially limited (i.e., the free end 222 cannot be displaced in the radial direction of the cap 210) by the clearance fit between the second limiting portion 2221 and the second limiting groove 2134, so that the atomized liquid is prevented from leaking out of the liquid filling hole 215 due to the displacement of the cap 210 in the axial direction of the cap 210 caused by the inversion or the like of the cap 210 after the free end 222 of the connector 220 covers the liquid filling hole 215.

In addition, when the free end 222 is separated from the mounting groove 213 and the injection hole 215 is exposed, the first limiting portion 2211 is in clearance fit in a part of the first limiting groove 2132 and the connecting end 221 abuts against the first groove side wall 2131, so that when the free end 222 moves to a position where the free end 222 can be separated from the mounting groove 213 and the injection hole 215 is exposed, the first groove side wall 2131 can block the connecting end 221, thereby not only ensuring that the free end 222 can accurately reach a position where the injection hole 215 can be completely exposed in a moving process in a direction away from the injection hole 215, but also avoiding that the stroke of the free end 222 when moving in a direction away from the injection hole 215 is too large to increase the stroke of the free end 222 when the free end 222 needs to move next to completely cover the injection hole 215. Moreover, by the clearance fit between the first limiting portion 2211 and the first limiting groove 2132, the connecting end 221 of the connecting member 220 can be axially limited (that is, the connecting end 221 cannot be displaced in the axial direction of the cover 210), so that the free end 222 of the connecting member 220 is prevented from being removed from the mounting groove 213, and the entire connecting member 220 is prevented from being removed from the mounting groove 213 due to the displacement of the cover 210 in the axial direction of the cover 210 in an inverted state or the like. Furthermore, since the fixing shaft 223 on the connecting end 221 is rotatably connected to the fixing groove 219 on the groove bottom wall 214 of the mounting groove 213, the connecting end 221 of the connecting piece 220 can be radially limited (i.e. the connecting end 221 cannot be displaced along the radial direction of the cover 210), so that the free end 222 of the connecting piece 220 can be limited in the mounting groove 213 or outside the mounting groove 213, and the connecting piece 220 can be always connected with the cover 210, thereby preventing the connecting piece 220 from being lost, and meanwhile, preventing the connecting piece 220 from being placed on a table top or other areas to cause pollution.

Since the mounting groove 213 penetrates at least one side wall 216 of the cover 210 in the above embodiment, in order to prevent the free end 222 of the connecting member 220 from sliding out of the mounting groove 213 to open the liquid injection hole 215 after covering the liquid injection hole 215 during transportation of the atomizer, and thus the atomized liquid leaks out of the liquid injection hole 215, in some embodiments, the free end 222 of the connecting member 220 may be clamped in the mounting groove 213 by means of clamping. Specifically, the second limiting groove 2134 is provided with a first clamping portion 2135 near the side wall 216 of the cover 210, and the second limiting portion 2221 is provided with a second clamping portion 2223 corresponding to the first clamping portion 2135, where when the free end 222 covers the liquid filling hole 215, the second clamping portion 2223 is clamped with the first clamping portion 2135, so that the free end 222 can be completely locked in the mounting groove 213 after the free end 222 covers the liquid filling hole 215, and the free end 222 of the connecting piece 220 is prevented from sliding out from the mounting groove 213 after covering the liquid filling hole 215, so that atomized liquid leaks from the liquid filling hole 215.

Optionally, the first clamping portion 2135 and the second clamping portion 2223 are both serrated, that is, by the serrated first clamping portion 2135 and the serrated second clamping portion 2223 being meshed with each other, the free end 222 can be completely locked in the mounting groove 213 after the free end 222 covers the liquid filling hole 215, so that the free end 222 of the connecting piece 220 is prevented from sliding out of the mounting groove 213 after the free end 222 covers the liquid filling hole 215, and thus the atomized liquid leaks out of the liquid filling hole 215. In addition, the material of at least one of the first clamping portion 2135 and the second clamping portion 2223 in the present embodiment is plastic, silica gel or rubber, so that at least one of the first clamping portion 2135 and the second clamping portion 2223 can be deformed, so that the first clamping portion 2135 and the second clamping portion 2223 are engaged with or disengaged from each other.

It should be noted that at least one of the first engaging portion 2135 and the second engaging portion 2223 may be other flexible materials capable of being deformed, so long as the first engaging portion 2135 and the second engaging portion 2223 can be engaged with or disengaged from each other, which is not limited in the embodiment of the present utility model.

In other constructions, referring to fig. 7 and 8, the connector 220 is slidably coupled within the mounting groove 213 in a direction parallel to the groove bottom wall 214 of the mounting groove 213, wherein the connector 220 covers the pour hole 215 when the connector 220 is slid to the first position in a direction proximate to the pour hole 215; when the connecting member 220 is slid to the second position in a direction away from the pour hole 215, the pour hole 215 is exposed. In this embodiment, it can be understood that the first position is a position that can enable the connector 220 to completely cover the liquid injection hole 215, and when the connector 220 slides to the first position along the direction approaching the liquid injection hole 215, specifically, the end portion of the connector 220 covers the liquid injection hole 215, or the middle portion of the connector 220 covers the liquid injection hole 215, or of course, the other positions of the connector 220 cover the liquid injection hole 215, so long as the liquid injection hole 215 can be covered, which is not particularly limited, and illustratively, as shown in fig. 7-8, when the connector 220 slides to the first position along the direction approaching the liquid injection hole 215, the end portion of the connector 220 near the liquid injection hole 215 covers the liquid injection hole 215 and abuts against the cover 210; the second position is a position where the connecting member 220 is completely exposed out of the injection hole 215, that is, when the connecting member 220 slides to the second position along a direction away from the injection hole 215, any part of the connecting member 220 does not cover the injection hole 215, so that the connecting member 220 can reciprocate in the mounting groove 213 and switch between the first position and the second position, thereby covering or exposing the injection hole 215.

In this embodiment, when the connecting piece 220 slides in the mounting groove 213, the connecting piece 220 can always move along the direction parallel to the groove bottom wall 214 of the mounting groove 213, so that the connecting piece 220 can not press the external air into the liquid storage cavity 110 of the atomizer from the liquid injection hole 215 in the process of covering the liquid injection hole 215, thereby preventing the liquid spraying phenomenon or snoring phenomenon of the atomizer caused by overlarge air pressure in the liquid storage cavity 110 of the atomizer in the heating process, and further effectively improving the use experience of the user.

In this embodiment, when the connecting member 220 is in the second position, if the connecting member 220 continues to slide along the direction away from the injection hole 215, the connecting member 220 can be completely separated from the mounting groove 213, and in this case, in order to prevent the connecting member 220 from being lost or contaminated when placed on a table top or other area, the separated connecting member 220 can be placed in a special container. It should be noted that, a mutually limiting structure (not shown) may be disposed in the connecting member 220 and the mounting groove 213, so that the connecting member 220 cannot be separated from the mounting groove 213, and the connecting member 220 can be hung in the mounting groove 213 after exposing the liquid injection hole 215, thereby avoiding the connecting member 220 from being lost or polluted.

Further, referring to fig. 7-8, in some embodiments, a third limiting groove 2136 is provided on a groove sidewall of the mounting groove 213, a third limiting portion 224 adapted to the third limiting groove 2136 is protruding on an outer periphery of the connecting piece 220, the third limiting portion 224 is clearance-fit in the third limiting groove 2136, and the connecting piece 220 is slidably connected in the mounting groove 213 through the fit between the third limiting portion 224 and the third limiting groove 2136. That is, through the clearance fit between the third limiting portion 224 and the third limiting groove 2136, not only the connecting piece 220 can be slidably mounted in the mounting groove 213, but also the connecting piece 220 can be axially limited (that is, the connecting piece 220 cannot be displaced along the axial direction of the cover 210), so that the situation that the connecting piece 220 falls out of the mounting groove 213 along the axial direction of the cover 210 due to the inverted state of the cover 210 and the like is avoided, and further, the situation that atomized liquid leaks out from the liquid injection hole 215 due to the fact that the connecting piece 220 falls out of the mounting groove 213 along the axial direction of the cover 210 after covering the liquid injection hole 215 can be avoided.

Since the mounting groove 213 penetrates at least one side wall 216 of the cover 210 in the above embodiment, in order to prevent the connection member 220 from sliding out of the mounting groove 213 in a direction away from the liquid injection hole 215 after covering the liquid injection hole 215 during transportation of the atomizer, the liquid injection hole 215 is opened, which results in leakage of the atomized liquid from the liquid injection hole 215. In some embodiments, the connector 220 may be snapped into the mounting slot 213 by way of a snap fit. Specifically, the third limiting groove 2136 is provided with a third clamping portion 2137 near the side wall of the cover 210, and the third limiting portion 224 is provided with a fourth clamping portion 2241 corresponding to the third clamping portion 2137, where, when the connecting piece 220 covers the liquid injection hole 215, the fourth clamping portion 2241 is clamped with the third clamping portion 2137, so that the connecting piece 220 can be completely fixed in the mounting groove 213 after the connecting piece 220 covers the liquid injection hole 215, and the atomized liquid is prevented from leaking out from the liquid injection hole 215 due to the fact that the connecting piece 220 slides out of the mounting groove 213 after the connecting piece 220 covers the liquid injection hole 215.

Optionally, the third clamping portion 2137 and the fourth clamping portion 2241 are saw-tooth shaped, that is, the saw-tooth shaped third clamping portion 2137 and the saw-tooth shaped fourth clamping portion 2241 are meshed with each other, so that the connecting piece 220 can be locked in the mounting groove 213 after the connecting piece 220 covers the liquid injection hole 215, and the atomized liquid is prevented from leaking out of the liquid injection hole 215 due to the fact that the connecting piece 220 slides out of the mounting groove 213 after the connecting piece 220 covers the liquid injection hole 215. In addition, the material of at least one of the third clamping portion 2137 and the fourth clamping portion 2241 in the present embodiment is plastic, silica gel or rubber, so that at least one of the third clamping portion 2137 and the fourth clamping portion 2241 can be deformed, so that the third clamping portion 2137 and the fourth clamping portion 2241 are engaged with or disengaged from each other.

At least one of the third engaging portion 2137 and the fourth engaging portion 2241 may be made of another flexible material capable of being deformed, so long as the third engaging portion 2137 and the fourth engaging portion 2241 can be engaged with or disengaged from each other, and the present utility model is not limited thereto.

After the liquid injection is completed, the connecting piece 220 moves towards the direction close to the liquid injection hole 215 and covers the liquid injection hole 215, so that the atomized liquid in the liquid storage cavity 110 can be prevented from leaking from the liquid injection hole 215.

In this embodiment, the mounting opening 120 is formed at the upper end of the atomizer, or the mounting opening 120 is formed at the lower end of the atomizer, or the mounting opening 120 is formed at the side end of the atomizer, so long as the liquid injection cap 200 can be mounted on the mounting opening 120, which is not particularly limited in the present utility model.
