Description

drip assisted push device

technical field

The invention relates to a drip bottle, which is a drip auxiliary pushing device.

Background technique

Press, there are quite a lot of public drip bottles on the market at present, most of which will include a bottle or container erected or hung on a hanger, and must be set at a height higher than the user, so that the bottle or container can be placed inside the bottle or container. The liquid flows into the human body, so it is quite inconvenient for the user to use, and it must be carried along with the hanger to move around.

Therefore, the present invention has developed a motor pumping assembly to pump out the liquid in the bottle or container, so that the bottle or container does not need to be erected or hung or set at a height higher than the user to pump the liquid in the bottle or container The pump is pumped into the human body, so the user does not need to carry the hanger to move around, which is quite convenient.

However, the rotational speed of the current pumping motor is quite high, and the flow control structure of the liquid inside it is not fine, so it still cannot achieve the low rotational speed and high torque or pump pressure and proper flow we need. The production cost of the sending motor is quite high, which does not meet the needs of the market.
