And because the utility model discloses all be equipped with one deck silica gel layer on steel ball surface and steel ball through-hole internal surface, make the liquid isolation in steel ball and the feeding bottle, prevent steel ball and liquid contact, improved the life and the security of this product greatly.

Description

Counterweight head for feeding bottle straw

technical field

The utility model relates to baby products, in particular to a counterweight head for feeding straws.

Background technique

When using an ordinary feeding bottle, the feeding bottle must be turned upside down so that the baby can suck. In order to facilitate the baby to suck milk, a straw is generally added to the feeding bottle. Some products have a metal ball at the bottom of the straw so that the bottom of the straw is always drooping and immersed in the milk. The metal ball is provided with a through hole. One end of the through hole is connected to the bottom end of the straw, and the other end of the through hole is the milk suction port. Although this feeding bottle straw is available, the metal ball is soaked in the liquid of the feeding bottle for a long time, and the metal iron ball will get rusty. If it is used for a long time, it will cause harm to the health of the baby.

Utility model content

The purpose of this utility model is to aim at the above-mentioned defects of the prior art, and to provide a counterweight head for feeding bottle straws with simple structure, anti-rust and non-toxic.

In order to solve the above-mentioned defects of the prior art, the technical solution provided by the utility model is: a counterweight head for feeding bottle straws, including a silica gel counterweight body, a stainless steel ball is arranged in the silica gel counterweight body, and the silica gel counterweight head The middle part of the body is provided with a first through hole, the middle part of the stainless steel ball is provided with a second through hole communicating with the first through hole, the inner wall of the second through hole is provided with a layer of silica gel, and the silica gel weight head body The lower end is provided with a suction pipe joint communicating with the first through hole.

As an improvement of the counterweight head for the feeding straw of the utility model, the middle part of the surface of the silicone counterweight head body is provided with an annular rib.

As an improvement of the counterweight head for the straw of the feeding bottle of the utility model, the connector of the straw is in the shape of a flat-bottomed cone.

As an improvement of the counterweight head for feeding straw of the utility model, the lower edge of the silica gel counterweight body is provided with a plurality of position-limiting protrusions at intervals.

Compared with the prior art, the utility model has the advantages that: because the utility model adopts the above-mentioned structure, when in use, the counterweight can be kept pressed against the inner bottom surface of the feeding bottle, so that the liquid pipe is always immersed in the milk, which can Avoid negative pressure in the liquid pipe and effectively prevent milk choking. And because the utility model is equipped with a layer of silica gel on the surface of the steel ball and the inner surface of the steel ball through hole, the stainless steel ball is isolated from the liquid in the feeding bottle, preventing the stainless steel ball from contacting the liquid, greatly improving the service life and safety of the product .

Detailed ways

Below just will further describe the utility model according to accompanying drawing.

As shown in Figures 1 and 2, a weight head for feeding bottle straws includes a silicone weight head body 1, a stainless steel ball 2 is arranged in the silicone weight head body 1, and a first through hole is provided in the middle of the silicone weight head body 1 3. The middle part of the stainless steel ball 2 is provided with a second through hole 4 communicating with the first through hole 3, and the inner wall of the second through hole 4 is provided with a layer of silica gel layer 5, and the lower end of the silica gel counterweight body 1 is provided with the first through hole 3 communicates with the suction pipe joint 6.

Preferably, an annular rib 7 is provided in the middle of the surface of the silicone weight head body 1 . It is convenient for this product to move in the feeding bottle and reduces the friction with the inner wall of the feeding bottle.

Preferably, the suction pipe joint 6 is in the shape of a flat-bottomed cone. Easy to attach bottle straws.

Preferably, a plurality of limiting protrusions 8 are arranged at intervals on the lower edge of the silicone weight head body 1 . Prevent this product from sucking the bottom of the feeding bottle when breastfeeding, so that there is a certain gap between the product and the bottom of the feeding bottle, so that milk can enter the straw.

When the utility model is in use, the silica gel weight head body 1 can prevent the stainless steel ball from contacting with the liquid, greatly improving the service life and safety of the product.
