In the present embodiment, as shown in fig. 1, the housing structure 2 may have: a housing body 21, an adapter cover 22, an adapter 23, and an elastic member 24.
Wherein the inside of the case body 21 may have an accommodating space for accommodating the core 3; the adapter cover 22 may be fixedly disposed on the housing body 21, for example, the adapter cover 22 may be fixedly mounted on the housing body 21 by a fixing member, or the adapter cover 22 may be integrally formed with the housing body 21; the adapter 23 is hollow and tubular, two ends of the adapter 23 in the length direction are open, the openings at the two ends can be used for the circulation of gas and/or liquid and other fluids, and the adapter 23 is located in the inner space enclosed by the inner wall of the adapter cover plate 22; the elastic member 24 is located between the adapter cover 22 and the adapter 23, and the adapter cover 22 movably supports the adapter 23 via the elastic member 24, whereby the adapter 23 becomes an adapter that can float inside the adapter cover 22.
According to the present embodiment, as shown in fig. 1, the floating adapter 23 is provided inside the housing structure 2, and the floating adapter 23 has a large moving range inside the adapter cover 22, so that the adapter 23 can be easily adjusted in position during the process of mounting the core 3 inside the housing structure 2, thereby being easily connected to the interface 31 of the core 3, and reducing the difficulty of mounting the core 3.
Fig. 2 is an enlarged schematic view of the vicinity of the adapter of the present embodiment, and as shown in fig. 2, the elastic member 24 may be provided on a side surface of the adapter 23 with respect to the longitudinal direction, so that the adapter 23 may float in the lateral direction. Further, the present embodiment may not be limited thereto, and for example, the elastic member 24 may be provided at an end of the adapter 23 in the length direction, whereby the adapter 23 may float in the length direction.
In the present embodiment, as shown in fig. 1, the housing structure 2 may further have: a locking pin 25 and a locking pin drive 26.
The lock pin 25 is movable relative to the housing body 21 so as to be switched between the first position and the second position. In the first position, the locking pin 25 protrudes at least partially through the housing body 21 into the interior of the housing body 21, and the portion protruding into the interior of the housing body 21 can block the core 3 accommodated in the interior of the housing body 21, thereby locking the core 3 accommodated in the interior of the housing body 21. In the second position, the locking pin 25 may be withdrawn from within the housing body 21, thereby allowing the core 3 to move within the housing body 21.
In the present embodiment, a locking pin driving part 26 is connected to the locking pin 25 for driving the locking pin 25 to move between the first position and the second position.
As shown in fig. 1, the lock pin driving portion 26 has a bent portion 261 bent in a direction away from the housing body 21 in the longitudinal direction. For example, one end 262 of the lock pin driving part 26 in the longitudinal direction is connected to the lock pin 25, and a position 263 between the bent part 261 and the one end 262 is pivotably attached to the outside of the case body 21. Thus, when the user presses the other end 264 of the locking pin driving part 26 in the longitudinal direction in the direction toward the housing body 21, the position 263 rotates, and the one end 262 moves in the direction away from the housing body 21, so that the locking pin 25 is lifted up to reach the second position; when the user releases the other end portion 264 of the locking pin driving portion 26, the one end portion 262 moves in the direction of the housing body 21, and the locking pin 25 drops to reach the first position.

In the present embodiment, in the process of moving the core 3 into the interior of the shell structure 2, the bottom end of the core 3 may be first placed into the interior of the shell structure 2, and then the middle and upper portions of the shell structure 2 are pushed so that the core 3 enters the interior of the shell structure 2 in the process of being brought from the inclined state to the upright state, whereby the core 3 can be mounted in a labor-saving manner. Furthermore, since the adapter 23 has a large range of movement within the housing structure 2, the interface 31 of the core 3 can be reliably connected with the adapter 23 during installation of the core 3 within the housing structure 2.
In the present embodiment, the mounting opening 27 may not be limited to be provided on the side of the housing structure 2, but may be provided on the top end of the housing structure 2, whereby the core 3 may be mounted inside the housing structure 2 in such a manner as to be vertically placed from top to bottom.

As shown in fig. 4, the housing structure 2 may also have a filter screen 29, which filter screen 29 is arranged inside the adapter 23. Thus, the filter net 29 can prevent dust and other foreign matters from entering the adapter 23.

Figure 6 is a schematic view of the flapper 291 in a position to open the adapter 23. As shown in fig. 6, the blocking plate 291 has, on the side facing the outside of the housing structure 2, a slope 293 inclined with respect to the mounting opening 27, which contacts the slope 293 when the core 3 moves into the housing structure 2 and pushes the blocking plate 291 to move against the elasticity of the spring 292 to open the opening 231 of the one end of the adapter 23.
Further, in the present embodiment, in the case where the core 3 is placed inside the case structure 2 in the top-to-bottom direction, the core 3 may be engaged with the internal structure of the case structure 2 by at least one of the following means, for example: the core 3 rotates in the longitudinal direction of the core 3 inside the housing structure 2, and engages when rotated to a predetermined angle; alternatively, the core 3 is held by an engaging member inside the housing structure 2; alternatively, the core 3 moves laterally inside the housing structure 2, reaches the engagement position, and engages with the internal structure of the housing structure 2.
