The present invention relates to a filling head, and more particularly to a filling device for preventing particle back suction.

The filling device of the existing bottled beverage is provided with a hole for conveying a beverage in a filling head of the filling mechanical device, and a bottle body of the bottled beverage carries particles, and the hole is guided by the filling head to inject the bottle In the bottle to complete a bottled beverage containing the contents of the granules or granules (if fruit in the juice).

However, when the filling head extends down into the bottle body, the hole of the filling head is exposed, and the beverage flows out from the hole of the filling head; when the filling is completed, the filling head is lifted up to close the hole. When the amount of the beverage injected into the bottle is too large, the beverage is sucked back from the hole of the filling head to achieve a quantitative effect of the injection amount of the bottle. However, the bottle is usually manually added by hand to add the granule or granule content to the bottle, and then the beverage is injected. Since the granule or the granule content is added to the bottle body, the hole of the filling head is injected. In the case of a beverage, the following problem arises: if the contents of the granules or granules are too small, it is easy to suck back from the protruding hole of the filling head, causing clogging of the internal piping, and each bottle after the beverage is sucked back. The amount of particles or granules originally set will be less, resulting in less uniform weight in each bottle; in addition, when the pores of the filling head are closed, the contents of the granules or granules are more It is easy to be caught, not only destroying the integrity of the contents of the particles or particles, but also cannot be stored during storage, and it also causes the internal pipeline to block.
