The front end of the piston rod 3 is provided with a connecting thread 31, the connection between the piston 2 and the piston rod 3 is realized through the threaded connection between the connecting thread 31 and the threaded hole 211, and finally the piston 2 and the piston rod 3 extend into the cavity 10 of the piston cylinder 1 together.

The pressing piece 4 is arranged at the rear end of the piston rod 2 and extends to the outside of the piston cylinder 1. Of course, the pressing member 4 may be integrally formed with the piston rod 2. Of course, the pressing member 4 may be integrally formed with the piston rod 2. The pressing piece 4 includes: the pressing end 41 and a guide tube 42 integrally retained with the pressing end 41.

The piston rod 1 is sleeved with a pressure spring 5, and the front end and the rear end of the pressure spring 5 respectively directly or indirectly act between the piston cylinder 1 and the piston rod 3. In this embodiment, a flange 32 is formed at the rear end of the piston rod 3, a bushing 6 is fixed in the piston cylinder 1, and the piston rod 2 is connected to the piston 2 after passing through the bushing 6. The front end of the compression spring 5 is pressed against the bushing 6, and the rear end of the compression spring 5 is pressed against the flange 32 (of course, it may also be directly pressed against the pressing member 4). The external force acting on the pressing piece 4 overcomes the elasticity of the pressure spring 5, and pushes the piston rod 3 to drive the piston 2 to compress the compression space 10 in the cavity; the thrust generated by the compression spring 5 on the piston rod 3 drives the piston 2 with a tendency to move away from the nozzle 11.

The compression space 10 is the space between the bushing 6 and the liquid nozzle 11 in the piston cylinder 1.

The bushing 6 is sleeve-shaped, and is inserted from the opening at the rear end of the piston cylinder 1, and the bushing 6 and the piston cylinder 1 form nested fit. For example: threads are formed on the side surface of the bushing 6, and the bushing 6 and the piston cylinder 1 can be connected through the threads; alternatively, a plurality of ribs 60 or grooves are formed on the side surface of the bushing 6, grooves or ribs corresponding to the ribs 60 or grooves are formed on the inner wall of the piston cylinder 1, and the two grooves or ribs are in clamping fit and fixed.

Since the piston rod 3 needs to pass through the bush 6 and to reciprocate, in order to ensure smooth operation of both, a sleeve 61 is provided on the bush 6 to be engaged with the piston rod 3. A sleeve 61 is fixed to the front end of the bush 6 and forms a shaft hole fit with the piston rod 3.

The guide cylinder 42 of the pressing piece 4 is inserted into the bushing 6, the guide cylinder 42 and the bushing 6 form shaft sleeve matching, and the piston rod 3 can be more stable in the reciprocating operation process through the matching between the guide cylinder 42 and the bushing 6, so that the swinging condition can not occur.

The embodiment also comprises a connector 9 of plastic material which cooperates with the spout 11. Referring to fig. 4, the connector 9 includes: a first channel 91 matched with the liquid nozzle 11 and a second channel 92 matched with the spray head of the perfume bottle, wherein the first channel 91 and the second channel 92 are communicated with each other. The connector 9 is used for connecting the utility model with a perfume bottle nozzle, and sealing is formed by the connector 9, so that leakage can be avoided in the perfume extraction process.

As shown in fig. 1 and 2, the present embodiment further includes a front cover 71 and a rear cover 72 respectively engaged with the front and rear ends of the piston cylinder 1 for aesthetic purposes and protection.

When the embodiment is used in combination with fig. 4, the first channel 91 of the connector 9 is sleeved on the liquid nozzle 11, and the second channel 92 is sleeved on the spray head 81 of the perfume bottle 8. Then, an external force is applied to the pressing member 4, and the external force overcomes the elastic force of the pressure spring 5, so that the piston rod 3 is pushed to drive the piston 2 to compress the compression space 10 in the cavity until the compression space 10 is completely compressed. When the external force is released, the compression spring 5 generates a pushing force to the piston rod 3 through the self elastic force, the piston 2 is driven to move from front to back, the compression space 10 is gradually released, and vacuum or negative pressure is formed, so that perfume in the perfume bottle 8 is pumped into the compression space 10. After the extraction is completed, the perfume extracted in the compression space 10 is injected into the perfume split charging bottle for the user to carry with him.

See fig. 5 and 6, which are a second embodiment of the present utility model. The second embodiment differs from the first embodiment in that:

The size of the compression space 10 can thus be changed. Thus, the amount of perfume extracted each time can be changed.

2. In the second embodiment, in order to stabilize the compression spring 5, the flange 32 at the rear end of the piston rod 3 cannot stabilize the compression spring 5, so that a spacer 33 is added, and after the spacer 33 is positioned by the flange 32, the space inside the spacer 33 can form an effective limit for the rear end of the compression spring 5.

3. In order to facilitate installation, in the second embodiment, the piston rod 3 and the piston 2 are not connected by a screw thread as in the first embodiment, but are connected by a snap fit, specifically: the support 21 of the piston 2 is formed by fastening a left support 211 and a right support 212 to each other, which are fixedly connected by a screw 213, and a clamping groove 210 is formed in the support 21. The front end of the piston rod 3 is formed with a boss 310 which is matched with the clamping groove 210, and the matching between the piston rod 3 and the piston 2 is realized through the previous matching of the boss 310 and the clamping groove 210.
