The outer diameter of the second portion 2302 is smaller than the outer diameter of the first portion 2301. The side of the side 120 facing away from the bottom 110 may abut against the side of the first portion 2301 facing away from the overlap 210, while the side 120 may be sleeved over the second portion 2302. Wherein the second portion 2302 may be interference fit within the side 120 to abut against the inner wall of the side 120.

Through the above design, the second portion 2302 of the second housing 200 can be moved into the accommodating groove 101 from one end of the first housing 100 until the side portion 120 abuts against the first portion 2301 during assembly of the host 20, so that quick and stable assembly between the first housing 100 and the second housing 200 can be achieved.

Of course, the fitting engagement between the first housing 100 and the second housing 200 is not limited thereto. For example, the first connecting portion 230 may also be sleeved on the side portion 120 to enable the second housing 200 to be assembled on the first housing 100. Also, for example, the first connection portion 230 and the side portion 120 may be assembled by a snap fit, a threaded connection, a pin connection, or the like. As another example, the overlap 210 may directly abut the side 120 to effect assembly.

To facilitate assembly of the host 20, the first housing 100 may be assembled from a plurality of structural members. In some embodiments, the first housing 100 may include a cover 300, and a surrounding wall 400 disposed between the overlap 210 and the cover 300. Wherein, the cover 300 is disposed on an end of the surrounding wall 400 facing away from the lap portion 210, for forming the bottom 110 of the first housing 100. Both ends of the surrounding wall 400 are abutted against the second housing 200 and the cover 300, respectively, for forming the side 120 of the first housing 100.

In the present utility model, the receiving groove 101 of the first housing 100 may be used to receive other structural members of the host 20.

Both ends of the surrounding wall 400 may be respectively sleeved on the first connection part 230 and the second connection part 130 to achieve the assembly between the first housing 100 and the second housing 200.

Wherein the second connection part 130 may be provided on a side of the bottom part 110 near the overlap part 210. The side of the surrounding wall 400 facing away from the overlap portion 210 may abut against the bottom 110, and the inner side of the surrounding wall 400 may be sleeved and abut against the second connecting portion 130. When the cover 300 is assembled, the second connecting portion 130 can be moved from the end of the surrounding wall 400 away from the overlap portion 210 into the inside of the surrounding wall 400, and moved to the end of the surrounding wall 400 to abut against the bottom 110, so as to realize the assembly of the cover 300 on the surrounding wall 400. Wherein the second connection portion 130 of the cover 300 may be interference-fitted to the inside of the surrounding wall 400.

In other embodiments, the first housing 100 may also be integrally formed. The integrally formed first housing 100 has a bottom 110 and a side 120 extending from an edge of the bottom 110, the bottom 110 and the side 120 enclose a receiving slot 101, and other structural members of the host 20 may be assembled in the receiving slot 101 from an end of the side 120 facing away from the bottom 110.

Wherein, the bottom 110 may be the cover 300 in the previous embodiment, and the side 120 may be the enclosure wall 400 in the previous embodiment. When the bottom 110 and the side 120 are integrally formed, the cover 300 and the enclosure wall 400 are considered to cooperate to form the first housing 100 as an integral structure. When the bottom 110 and the side 120 are separately formed and assembled to form the first housing 100, respectively, the cover 300 and the surrounding wall 400 may be considered to be separate members and assembled to form the first housing 100, respectively.

With continued reference to fig. 4, and with reference to fig. 5 and fig. 6 in combination, fig. 5 is a schematic structural view of a second housing according to some embodiments of the present utility model, and fig. 6 is a schematic structural view of a first sealing member according to some embodiments of the present utility model.

In some embodiments, the end cap portion 220 of the second housing 200 extends from the outer periphery of the through-opening 202. When the overlap portion 210 overlaps the notch of the accommodating groove 101, the end cap portion 220 is located in the accommodating groove 101 and may have a gap with the side portion 120, so as to avoid the difficulty in assembly caused by friction between the end cap portion 220 and the side portion 120.

Alternatively, the first connection portion 230 of the second housing 200 may surround the end cap portion 220 and be spaced apart from the end cap portion 220, so that when the first connection portion 230 abuts against the side portion 120, the end cap portion 220 may move into the receiving groove 101 and be spaced apart from the side portion 120.

Wherein the gap between the first connection portion 230 and the end cap portion 220 also facilitates an interference fit of the second portion 2302 of the first connection portion 230 with the side portion 120. When the second portion 2302 moves into the receiving groove 101, the second portion 2302 may deform and deflect toward the end cap 220 under the interference of the inner wall of the side portion 120, so that the second portion 2302 located in the receiving groove 101 has a deformation recovery tendency toward the side portion 120, which is beneficial to improving the mating tightness between the second portion 2302 and the side portion 120. Wherein the gap between the first connection portion 230 and the end cap portion 220 may provide the space required for the second portion 2302 to deform and deflect.

Optionally, a first seal 600 of the host 20 may be provided between the end cap portion 220 and the side portion 120 to seal off the gap between the end cap portion 220 and the side portion 120, thereby improving the efficiency of gas flow from the receiving groove 101 to the docking groove 201.

In an embodiment, the bottom portion 110 may be provided with a first through hole 103 communicating with the receiving groove 101, and the cap portion 220 may be provided with a second through hole 203 communicating with the receiving groove 101, so that gas may flow from the first through hole 103 into the receiving groove 101 and through the second through hole 203 into the docking groove 201. When the atomizer 10 moves to the docking tank 201 to dock the host 20, the gas flowing into the docking tank 201 may further flow into the atomizer 10.

The first seal 600 may be sleeved on an end of the end cover 220 near the bottom 110, and is in interference fit with the side 120. The end cap portion 220 may be spaced apart from the bottom portion 110 to form the gas space 102 between the end cap portion 220 and the bottom portion 110. The first through hole 103 and the second through hole 203 are respectively communicated with the gas space 102. The first seal 600 may prevent gas within the gas space 102 from flowing into the gap between the end cap portion 220 and the side portion 120 to increase the efficiency of gas flow from the gas space 102 to the docking slot 201.

Optionally, the end cap portion 220 has a groove bottom wall 2210 and groove side walls 2220 that cooperatively enclose the mating groove 201. Wherein the groove sidewall 2220 is disposed around the outer periphery of the through hole 202. The groove bottom wall 2210 is disposed at an end of the groove side wall 2220 facing away from the lap joint portion 210, and is connected with the groove side wall 2220 in a bending manner. The first seal 600 may be sleeved on an end of the groove sidewall 2220 adjacent to the groove bottom wall 2210 and abuts against the side portion 120 to seal the gap between the end cap portion 220 and the side portion 120.

To enhance the sealing effect of the first seal 600 on the gap between the end cap portion 220 and the side portion 120, the first seal 600 may be sleeved at the junction 2230 between the groove side wall 2220 and the groove bottom wall 2210. The joint 2230 may be a portion where the groove bottom wall 2210 and the groove side wall 2220 are joined, that is, a portion of the joint 2230 is formed by the groove bottom wall 2210 and another portion is formed by the groove side wall 2220. The bond 2230 may also be a partial structure of the end cap 220 that is distinct from the groove bottom wall 2210 and the groove side wall 2220.

For convenience of description, the joint 2230 is hereinafter referred to as a portion of the end cap 220 that is distinguished from the groove bottom wall 2210 and the groove side wall 2220, and at this time, a portion of the end cap 220 disposed between the joint 2230 and the lap joint 210 is referred to as the groove side wall 2220, and a portion of the end cap 220 disposed at an end of the joint 2230 facing away from the lap joint 210 is referred to as the groove bottom wall 2210.

In some embodiments, the bond 2230 can include a first sub-portion 2231 that is looped around the outer peripheral edge of the groove bottom wall 2210, and a second sub-portion 2232 that extends from an end of the first sub-portion 2231 that faces away from the groove bottom wall 2210 to an end of the groove side wall 2220 that is proximate to the groove bottom wall 2210. Wherein the second sub-portion 2232 can be bent between the first sub-portion 2231 and the slot sidewall 2220. The first seal 600 may be sleeved on the first sub-portion 2231 and abut or abut against the second sub-portion 2232 to achieve a tight fit with the end cap portion 220.

Alternatively, the first seal 600 comprises a first seal portion 610 that is sleeved around the first sub-portion 2231, i.e., the first seal portion 610 may be provided with an opening 601 that is adapted to the outer diameter of the groove bottom wall 2210. When the first sealing portion 610 is sleeved on the first sub-portion 2231, one end of the first sealing portion 610 facing away from the bottom 110 abuts against or abuts against the second sub-portion 2232.
