In one embodiment of the present application, the cross-sectional area of ​​the liquid guiding hole 241 is circular, rectangular, square or other shapes.

[0053] The present application provides a liquid storage device 1, such as Figure 5-6 As shown, it includes a first shell 11, a first bracket 12 and a first sealing member 4. The first shell 11 and the first bracket 12 define a first liquid storage chamber 13, and the first bracket 12 defines a part of a liquid outlet 121, and the liquid outlet 121 and the first liquid storage chamber 13 are in liquid conduction. The first sealing member 4 is located between the first shell 11 and the first bracket 12, and is used to prevent the liquid matrix in the first liquid storage chamber 13 from leaking from between the first shell 11 and the first bracket 12. The first sealing member 4 includes a sealing film 41, which is located on one side of the liquid outlet 121 and seals the liquid outlet 121. The liquid reservoir 1 is well sealed by the sealing film, so that the liquid matrix in the liquid reservoir 1 is well preserved, preventing it from contacting with air and thus deteriorating, and extending its shelf life.

[0054] In one embodiment of the present application, Figure 7-8 As shown, the first sealing member 4 defines a through hole 42, and the through hole 42 constitutes another part of the liquid outlet 241. In one embodiment of the present application, the sealing film 41 includes a silicone film, which can be punctured by other objects, so that the liquid matrix in the liquid reservoir 1 flows out, and the punctured silicone film is wrapped around the liquid guide column 24 to prevent the liquid matrix from leaking from between the first sealing member 4 and the liquid guide column 24.

During the process of installing the liquid reservoir 1 on the device body 2 , the third protrusion 46 can play a buffering role.

[0058] In one embodiment of the present application, Figure 3-4 As shown, before the liquid reservoir 1 is installed in the device body 2, the sealing film 41 of the first sealing member 4 seals the first liquid storage chamber 13, so that the liquid matrix in the liquid reservoir 1 is well sealed and preserved. After the liquid reservoir 1 is installed in the device body 2, the liquid guide column 24 of the device body 2 punctures the sealing film 41, so that the liquid guide hole 241 on the liquid guide column 24 and the first liquid storage chamber 13 are in liquid conduction, so that the first liquid storage chamber 13 of the liquid reservoir 1 provides the liquid matrix to the second liquid storage chamber 23 of the device body 2. In one embodiment of the present application, the end of the liquid guide column 24 is tapered, so that when the liquid reservoir 1 is installed in the device body 2, the sealing film 41 of the sealing member 4 is punctured, so that the liquid guide hole 241 provides a liquid flow path for the liquid matrix in the first liquid storage chamber 13 to flow to the second liquid storage chamber 23. In one embodiment of the present application, the sealing film 41 includes a silicone film, and after the conical liquid-conducting column 24 punctures the sealing film 41, the punctured silicone film can still wrap the outer wall of the liquid-conducting column 24, so that the punctured silicone film still has a sealing effect on the liquid-conducting column 24. In one embodiment of the present application, the sealing film 41 is also conical toward the first liquid storage cavity 13, which can be adapted to the shape of the liquid-conducting column 24 on the one hand, and on the other hand, the conical sealing film 41 can play a guiding role in the process of installing the liquid reservoir 1 to the device body 2, so as to facilitate the installation of the liquid reservoir 1 to the device body 2.

[0059] In one embodiment of the present application, the liquid reservoir 1 includes a first sealing member 4, the first sealing member 4 defines a through hole 42, the through hole 42 constitutes another part of the liquid outlet hole 241, and the liquid outlet hole 121 is used to accommodate the liquid guide column 24. In one embodiment of the present application, the first sealing member 4 includes a sealing flange 44, and the sealing flange 44 is located on the side of the liquid guide hole 241 away from the first liquid storage chamber 13, so that the first sealing member 4 and the end of the liquid guide column 24 away from the liquid guide hole 241 are sealed, so that the liquid matrix in the first liquid storage chamber 13 can only enter the second liquid storage chamber 23 from the liquid guide hole 241, but cannot enter the second liquid storage chamber 23 from between the first sealing member 4 and the liquid guide column 24.

[0060] In one embodiment of the present application, the sealing film 41 is located on the side of the sealing flange 44 away from the first liquid storage chamber 13. During the process of installing the liquid reservoir 1 to the device body 2, after the liquid-conducting column 24 pierces the sealing film 41, the sealing film 41 surrounds the liquid-conducting column 24 after piercing, so that the liquid matrix in the first liquid storage chamber 13 will not leak from between the first liquid storage chamber 13 and the liquid-conducting column 24; then as the liquid reservoir 1 is installed, the sealing flange 44 is located between the first sealing member 4 and the liquid-conducting column 24, so that the sealing effect between the first sealing member 4 and the liquid-conducting column 24 is better. In one embodiment of the present application, the process of installing the liquid reservoir 1 to the device body 2 is one-step, that is, the liquid-conducting column 24 quickly pierces the sealing film 41 and passes through the sealing flange 44, so that the liquid matrix in the first liquid storage chamber 13 will not leak from between the first sealing member 4 and the liquid-conducting column 24.
