Wherein, the elastic fastener 1340 and the rebound part 1341 are configured to have a vertical difference in height relative to each other. In other words, the elastic fastener 1340 and the rebound part 1341 are not disposed on the same horizontal plane, so that when the front end of the elastic fastener 1340 and the front end of the rebound part 1341 are opposite to each other, there will be a horizontal spacing and a vertical spacing between them.

[0035] In addition, the front end of the elastic fastener 1340 is provided with a snap bead 13400, and when the snap switch 13 is embedded into the assembly opening 1210 and movably assembled into the feeder 12, a side hopper mouth of the measuring hopper 132 is connected to the feed inlet 1200 to receive and accommodate a fixed amount of the feed, and the sealing boss 133 connects and seals the feed outlet 1211, and the snap bead 13400 is adjacent to one of the acoustic positioning ribs 1212, and the rebound part 1341 is adjacent to the inner wall on a side of the assembly frame part 121.

In this way, the setup of the rectangular sealing boss 133 and the acoustic positioning rib 1212 improving the shifting position configuration of the feed outlet 1211 by controlling the pushing progress of the snap switch 13. For example, in the measuring hopper 132 with a volume of 30 ml, the pushing progress of the snap switch 13 is controlled by the rectangular sealing boss 133 and the acoustic positioning rib 1212 to define three shifting positions in order to adjust the amount of the feed discharged from the feed outlet 1211 at a time to 10 ml, 20 ml or 30 ml, so as to realize the variable quantitative feeding effect.

[0036] When the user wants to use the highly productive eco-friendly quantitative feeding device 1 for feeding and applies a pressing force to the pressing part 131 in a direction, the elastic fastening structure 134 is compressed to move towards an opposite direction, so that the rebound part 1341 and the elastic fastener 1340 are contracted in a direction towards the center of the snap switch 13. At this time, the front end of the rebound part 1341 abuts against the inner wall on a side of the assembly frame part 121 and slides and contracts, and the snap bead 13400 successively slides through the acoustic positioning ribs 1212 one by one and emits a sound, so as to achieve the effect of feeding back the pushing progress by the sound. Meanwhile, the snap bead 13400 can be snapped to a side of each acoustic positioning rib 1212 to achieve an anti-slip effect, so as to reduce the continuous output requirement of the pressing force and facilitate an ease of use.

The present disclosure involves a simple structure and very little components, thus simplifying the production process. In the production process, after the containing can 10 is formed by a plastic molding machine or a blow molding machine, the snap switch 13 is installed in the feeder 12 and the can cover 120 of the feeder 12 is installed with the moisture-resisting film 11 such as aluminum foil or aluminum film, the containing can 10 with its can mouth facing upward is placed on a production line for automatic weighing and filling of the feed, and a capping machine is used to screw the feeder 12 with the moisture-resisting film 11 to the can mouth of the containing can 10, and send the feeder 12 to an automatic electromagnetic induction sealing machine to seal the moisture-resisting film 11 onto the can mouth of the containing can 10. The moisture-resisting film 11 prevents the penetration of moisture and enhances the shelf life of the feed 2 for at least three times before unpack or use. In this way, by embedding the snap switch 13 into the assembly opening 1210, and connecting the screw thread 100 and the screw thread 1202, it realizes the fully automatic production line and achieves the high efficiency fully automatic production process that can fill and produce more than 60 cans per minute. Since it is convenient for the users to purchase the refill packs for the use of the highly productive environmentally friendly quantitative feed feeder 1 continuously, the present disclosure complies with the concept of producing eco-friendly products and conserving earth's resources.
