Liquid injection device and method

Abstract

A liquid injection device and a liquid injection method are provided. The liquid injection device injects a liquid into a liquid storage assembly. The liquid storage assembly includes a liquid storage tube and a liquid storage element in the liquid storage tube. The liquid injection device includes a receiving portion with a receiving groove. The receiving groove receives an atomizable base liquid. The liquid injection device further includes communication holes communicating with the receiving groove. The receiving portion is mounted at an end of the liquid storage tube, thereby causing the atomizable base liquid in the receiving portion to be injected into the liquid storage element through the communication holes.

1 . A liquid injection device for injecting an atomizable base liquid into a liquid storage assembly, the liquid storage assembly comprising a liquid storage tube and a liquid storage element in the liquid storage tube, the liquid injection device comprising:
 a receiving portion defining a receiving groove, the receiving groove configured to receive the atomizable base liquid; and   a plurality of communication holes communicating with the receiving groove,   wherein the receiving portion is configured to be mounted at an end of the liquid storage tube, thereby causing the atomizable base liquid in the receiving portion to be injected into the liquid storage element through the plurality of communication holes.   
     
     
         2 . The liquid injection device of  claim 1 , wherein the receiving portion defines an opening; the liquid injection device further comprises a liquid injection portion disposed on a side of the receiving portion away from the opening; the liquid injection portion has a bottom wall; the plurality of communication holes is defined on the bottom wall; the liquid injection portion is configured to extend into the end of the liquid storage tube. 
     
     
         3 . The liquid injection device of  claim 2 , wherein a barrier column protrudes from the bottom wall; the barrier column is configured to extend into a mounting hole of the liquid storage element. 
     
     
         4 . The liquid injection device of  claim 3 , wherein the barrier column is disposed in a center of the bottom wall. 
     
     
         5 . The liquid injection device of  claim 2 , wherein the plurality of communication holes is distributed in a circle around a center of the bottom wall. 
     
     
         6 . The liquid injection device of  claim 2 , wherein an inner diameter of each of the plurality of communication holes decreases along a direction from the receiving portion to the liquid injection portion. 
     
     
         7 . The liquid injection device of  claim 2 , wherein a through pipe is disposed on the bottom wall; the through pipe communicates with the plurality of communication holes. 
     
     
         8 . The liquid injection device of  claim 2 , wherein a sidewall of the liquid injection portion defines an external thread; the external thread is configured to engage with an internal thread of the liquid storage tube. 
     
     
         9 . The liquid injection device of  claim 2 , wherein along a direction from the liquid injection portion to the receiving portion, the bottom wall is convex to form a convex portion; the plurality of communication holes is arranged at a connection region between the convex portion and a sidewall of the receiving portion. 
     
     
         10 . A liquid injection method comprising:
 providing a liquid injection device, the liquid injection device comprising a receiving portion defining a receiving groove and a plurality of communication holes communicating with the receiving groove;   providing a liquid storage assembly, wherein the liquid storage assembly comprising a liquid storage tube and a liquid storage element in the liquid storage tube, the liquid storage tube has a first end and a second end, a first sealing plug is mounted at the first end of the liquid storage tube;   mounting the liquid injection device on the second end of the liquid storage tube;   loading the atomizable base liquid into the liquid injection device through a liquid injection machine, so that the atomizable base liquid is injected into the liquid storage element through the plurality of communication holes; and   keeping the liquid storage assembly static, thereby causing the liquid storage element to adsorb the atomizable base liquid.
