The first extension portion 1313 of the latch 131 is pivotally disposed on the first pivot end 1321 of the connecting rod 132, so that the connecting rod 132 can drive the latch portion 1312 of the latch 131 to engage the latch groove 1121 of the guide column 112, and make the two second fluid connectors 122 connected to the two first fluid connectors 113 respectively, and make the second electrical connector 123 connected to the first electrical connector 114.

[0082] The handle member 133 is pivoted at another location of the housing 1211 of the fluid supply body 121. In detail, the handle member 133 includes a second pivoting portion 1331, a second extension portion 1332 and an operating portion 1333. The second pivoting portion 1331 is pivoted at another location of the housing 1211. In other words, the rotation axis of the buckle 131 is not coaxial with the rotation axis of the handle member 133. The second extension portion 1332 and the operating portion 1333 are connected to the second pivoting portion 1331 and protrude in different directions. The second extension portion 1332 is pivoted at the second pivot end 1322. The operating portion 1333 is used to drive the handle member 133 to rotate relative to the housing 1211. The fluid supply assembly 12 further includes a grip member 125, which is connected to the two operating portions 1333 of the second handle member 133 so that the grip member 125 drives the two handle members 133 together.

[0083] In the present embodiment, since the fluid supply module 10 is provided with a locking assembly 13, and the accommodating shell 11 is provided with a guide post 112 with a snap groove 1121, when the fluid supply assembly 12 is installed in the accommodating shell 11 or removed from the accommodating shell 11, there is no need to open the accommodating shell 11 and perform cumbersome assembly and disassembly steps, for example, through additional assembly elements and disassembly elements. Instead, the two first fluid connectors 113 and the two second fluid connectors 122 can be connected or disconnected at one time, and the first electrical connector 114 and the second electrical connector 123 can be connected or disconnected at one time, so as to complete the assembly or disassembly of the fluid supply assembly 12, thereby improving the convenience of assembling and disassembling the fluid supply module 10.

[0084] In this embodiment, the fluid supply body 121 may further include a fan 124, and the housing 1211 of the fluid supply body 121 may further have a plurality of vents 12111. The fan 124 is disposed on the housing 1211 and is used to form a heat dissipation airflow through the vents 12111 to dissipate heat in the space within the fluid supply body 121.

In this way, the fluid supply assembly 12 can be removed from the accommodating shell 11.

[0089] On the contrary, when the user wants to install the fluid supply assembly 12 to the accommodating shell 11, first, the user pushes the handle 125 in the opposite direction of direction C to drive the fluid supply assembly 12 to move into the accommodating shell 11 in the opposite direction of direction C. Then, the user rotates the handle 125 in the opposite direction of direction A, so that the handle 133 connected to the handle 125 drives the buckle 131 to rotate in the opposite direction of direction B through the connecting rod 132, so that the buckle portion 1312 of the buckle 131 is buckled in the buckle groove 1121 of the guide column 112. At this time, the second fluid connector 122 of the fluid supply assembly 12 is connected to the first fluid connector 113 of the accommodating shell 11, and the second electrical connector 123 of the fluid supply assembly 12 is connected to the first electrical connector 114 of the accommodating shell 11. In this way, the assembly of the fluid supply assembly 12 and the accommodating shell 11 is completed.

[0090] According to the replaceable fluid supply device and fluid supply module of the above-mentioned embodiments, since the fluid supply module is provided with a locking assembly and the accommodating shell is provided with a guide column with a snap groove, when the fluid supply assembly is installed in the accommodating shell or removed from the accommodating shell, there is no need to open the accommodating shell and perform tedious assembly and disassembly steps, for example, through additional assembly components and disassembly components. Instead, the two first fluid connectors and the two second fluid connectors can be connected or disconnected at one time, and the first electrical connector and the second electrical connector can be connected or disconnected at one time, so as to complete the assembly or disassembly of the fluid supply assembly, thereby improving the convenience of assembly and disassembly of the fluid supply module.
