Under the guidance of the above-mentioned idea, the above-mentioned features can be combined or selectively used according to specific requirements, and the present invention provides several specific exemplary embodiments as follows.
Example 1
Referring to fig. 2, fig. 3, fig. 4 and fig. 5, in this embodiment, the liquid outlet pipe 3 is a pipe structure, one end close to the buffer liquid storage pipe 1 is a closed end, one end far away from the buffer liquid storage pipe 1 is an open end, the end surface of the closed end is the liquid squeezing surface 31, the end port of the open end is the second outlet 35, the inside is the liquid outlet channel 34, and the plurality of through holes 36 are disposed on the side wall of the liquid outlet pipe 3. The sealing portion 13 is of an annular sealing structure, and the through hole 36 is closed by the inner wall of the ring in an initial state where the liquid outlet pipe 3 is not pressed.
Therefore, when the open end of the liquid outlet pipe 3 is pressed, the liquid outlet pipe moves towards the cache liquid storage pipe 1, and simultaneously moves relative to the sealing part 13, the volume of the cache liquid storage pipe 1 is reduced when the liquid outlet pipe 1 moves towards the cache liquid storage pipe 1, meanwhile, the liquid squeezing surface 31 squeezes the liquid in the cache liquid storage pipe 1 to provide liquid outlet pressure, and the relative movement enables at least one through hole 36 to be opened to be communicated with the cache liquid storage pipe 1, so that a liquid outlet passage of the main liquid storage chamber 2-the cache liquid storage part 14-the through hole 36-the liquid outlet channel 34-the second opening 35-the liquid outlet part 15-the first opening 11-the liquid using end is formed.
Further, set up the spring as canceling release mechanical system 4 between the blind end of drain pipe 3 and buffer memory liquid reserve pipe 1, set up the check valve between buffer memory liquid reserve pipe 1 and main stock solution room 2 to the blind end at drain pipe 3 is connected to the one end of spring, and the other end is connected in the operating portion of check valve. When drain pipe 3 pressurized, pressure passes through the operating portion of spring effect check valve for the check valve is closed, disconnects the intercommunication between main stock solution room 2 and the buffer memory stock solution pipe 1. At this time, the volume of the buffer liquid storage tube 1 can be ensured to be reduced along with the pressure movement of the liquid outlet tube 3. When the pressure is removed, the spring stops acting on the operation part of the one-way valve, the one-way valve is opened, the main liquid storage chamber 2 is communicated with the cache liquid storage pipe 1, the liquid outlet pipe 3 is rapidly reset, and each through hole 36 is sealed by the sealing part 13 again.
For example, to ensure the resetting of the liquid outlet pipe 3, the closed end thereof may be configured as a cover structure as the limiting portion 33, i.e., the outer diameter of the end of the closed end should be larger than the inner diameter of the ring of the sealing piece, and cover the sealing portion 13.
Further, the sealing sheet is a movable component, a protruding portion 37 is disposed on a side of the sealing sheet away from the cache liquid storage tube 1, and the protruding portion 37 may be a circumferentially continuous mechanism or a circumferentially discontinuous structure. At this time, after the through hole 36 is exposed by the movement of the liquid outlet pipe 3, the projection 37 is further moved by the further movement of the liquid outlet pipe 3 to push the sealing part 13 to move along with the pressure direction, and the movement of the sealing part 13 can further reduce the volume of the buffer liquid storage pipe 1. When the pressure is removed, the cover structure will drive the sealing portion 13 to reset.
Example 2
Referring to fig. 6, 7, 8, and 9, in this embodiment, the liquid outlet pipe 3 is a pipe structure or a column structure, one end of the liquid outlet pipe, which is close to the buffer liquid storage pipe 1, is a closed end, an end surface of the closed end is a liquid squeezing surface 31, and a part of a pipe body of the liquid outlet pipe 3 is a circular truncated cone, for example, the closed end may directly adopt a circular truncated cone, and the circular truncated cone serves as the limiting portion 33. The cross-section of this round platform is to keeping away from the convergent of buffer memory liquid storage pipe 1 direction, and sealing portion 13 sets up between the outer wall of round platform and the inner wall of buffer memory liquid storage pipe 1. When the liquid outlet pipe 3 is pressed to move, the circular table on the liquid outlet pipe 3 moves towards the buffer liquid storage pipe 1 along the pressure direction, and a gap between the circular table and the sealing part 13 is opened, so that the gap becomes a liquid outlet. Thereby, a liquid outlet passage for the liquid end, which is a gap between the main liquid storage chamber 2, the buffer liquid storage part 14, the limiting part 33 and the sealing part 13, the liquid outlet part 15, the first opening 11 is formed.
