The existing piston type discharging mechanism has the disadvantages that when a new bottle body A2 needs to be replaced, a sealing film is fixedly arranged on a bottle mouth A21 of the bottle body A2, the bottle body A2 is difficult to tear through manpower, and after the sealing film is broken through by using a sharp tool, the bottle body A2 can be replaced to output fluid in a subsequent bottle body A2, so that the use is inconvenient, and the improvement is needed.
Disclosure of Invention
The utility model aims to provide a piston type discharging mechanism to solve the problems in the background technology.
In order to achieve the purpose, the utility model provides the following technical scheme:
the utility model provides a piston discharge mechanism, includes piston, bottle and bottle seat, the bottle seat has the holding tank, it is most advanced to be equipped with cavity down on the holding tank, holding tank detachably cover is established on the bottle, the bottle includes bottleneck and body, the bottleneck establish on the bottle and with the most advanced cooperation of cavity, piston sealing connection is in the bottle.
Further, the holding tank includes mounting groove and lower mounting groove, it establishes outside the bottle neck to go up the mounting groove cover, mounting groove detachably cover is established outside the body down.
Furthermore, the upper mounting groove is hermetically connected with the bottle mouth.
Further, the lower mounting groove is connected with the bottle body through threads or buckles.
Furthermore, a matching groove matched with the hollow tip end is formed in the bottle mouth, and the matching groove is matched with the hollow tip end.
The utility model has the beneficial effects that:
the bottle seat is assembled with the bottle body through the holding tank, and at the in-process of bottle seat and bottle body equipment, the bottle neck moves with cavity point end in opposite directions, and the sealing film on the bottle neck receives the most pointed extrusion degree of cavity to increase gradually, and when the bottle seat finishes with bottle body equipment, the cavity point end is disclosed the sealing film and is broken. The utility model has the advantages that the sealing film on the bottle mouth is not required to be poked by a sharp tool in advance, and the use is convenient.

FIG. 4: prior art assembly schematic.
Detailed Description
The utility model is further described below with reference to the accompanying drawings:
referring to fig. 1 and 2, a piston type discharging mechanism includes a piston 1, a bottle body 2 and a bottle seat 3, wherein a receiving groove 31 is formed below the bottle seat 3, a hollow tip 32 is formed on the receiving groove 31, the receiving groove 31 is detachably sleeved on the bottle body 2, the bottle body 2 includes a bottle mouth 21 and a bottle body 22, the bottle mouth 21 is formed on the bottle body 22 and located under the hollow tip 32, the bottle mouth 21 is communicated with the bottle body 22, an opening is formed below the bottle body 22, the piston 1 is hermetically connected in the bottle body 2, a lower annular groove is formed in the periphery of the piston 1, and a lower sealing ring is formed between the lower annular groove and the inner peripheral wall of the bottle body 2.
The bottle seat 3 is provided with an upward discharging nozzle which is positioned above the hollow tip and communicated with the hollow tip.
Referring to fig. 1, the accommodating groove 31 includes an upper mounting groove 311 and a lower mounting groove 312, the upper mounting groove 311 is sleeved outside the bottle mouth 21, and the lower mounting groove 312 is connected to the bottle body 22 by a screw thread or a snap connection, so that the accommodating groove 31 is detachably connected to the bottle body 22.
The upper mounting groove 311 is connected with the bottle mouth 21 in a sealing way. An upper annular groove is formed in the periphery of the bottle mouth 21, and an upper sealing ring is arranged between the upper annular groove and the inner peripheral wall of the upper mounting groove 311.
