The present invention relates to a liquid material supply device for a vending machine, and more particularly, can be easily installed without changing the structure in an existing vending machine, and can be automatically sold to prevent malfunction and damage due to adhesion of the liquid material. The present invention relates to a liquid material supply apparatus.

Vending machines are used to provide various kinds of products such as food and beverages. Among these, vending machines that provide drinks such as coffee or tea in a cup are usually provided with a material container for storing powdered materials, a hot water supply device for supplying hot water, the material supplied from the material container and the hot water supplied from the hot water supply device. It is provided with a stirring device for mixing the pour the beverage made in the stirring device to the cup of the withdrawal through the discharge pipe to provide the user.

By the way, since the conventional vending machine is made of a mixture of the powder material and hot water to make a beverage, it is possible to provide a type of beverage that is provided with an instant powder material, such as coffee, but not the type of beverage For example, in the case of green tea is impossible to provide, due to the problem of dissolution of the material was difficult to provide cold drinks.

Furthermore, in the process of mixing the material and hot water, undissolved powder residues remain and adhere to each part of the beverage transfer path, and the adhered residues deteriorate with time, resulting in poor taste and poor hygiene. There was a downside.

In order to compensate for this disadvantage, there is a vending machine that provides a beverage using a liquid material instead of a powder. This is to supply the concentrated liquid material mixed with water, and can provide not only coffee but also various kinds of beverages such as green tea or herbal tea, and also to provide cold drinks, and contamination problem due to adhesion of powder materials. There is no advantage.

However, since the conventional liquid material supply vending machine has to install the whole apparatus separately from the existing powder material supply vending machine, there is a problem in that the cost is high in terms of installing the vending machine.

In addition, since the gear pump is provided for supplying the liquid material, and a separate solenoid valve is provided for the supply amount adjustment, the structure of the liquid material supply part has a complicated problem, and the diaphragm type solenoid valve is provided. The liquid solution adheres to the pads, resulting in poor operation, and there is a problem in that the driving unit is damaged by overload.

The present invention is to solve the problems described above, can be easily installed without changing the structure in the existing vending machine, supplying a liquid material for a vending machine that can prevent malfunction and damage due to adhesion of the liquid material It is an object to provide a device.
