Vending liquid constant pressure metering device is configured.

With the above configuration, the liquid product stored in the storage tank is supplied to the outside at a constant pressure and amount without contamination from the outside and evaporation of volatile components.

Description

Liquid dispenser of static pressure and quantity for vending machine}

The present invention relates to an apparatus for supplying a liquid product at a constant pressure and quantity in a vending machine for selling gargle liquid, persimmon vinegar, alcoholic beverage, and the like without contamination from outside and evaporation of volatile components.

In the conventional carbonated beverage liquid product vending machine, the liquid product is pressurized and filled with a gas such as carbon dioxide in a high pressure container for storing the liquid, so as to discharge the liquid product at the same time.

However, when this method is used for liquids other than carbonated drinks, dissolution of carbon dioxide in liquids is inevitable, and the taste and aroma of liquids such as gargle and persimmon vinegar change, and the pressure in the container changes according to the change of ambient temperature. In order to solve this problem, it is inevitable to provide an additional cooling device and an expensive valve or pump in the vending machine.

Therefore, it is not suitable in liquid product vending machines such as gargle liquid or persimmon vinegar, which is as small and inexpensive as possible and should not change taste and aroma.

In view of the above problems, the subject of the present invention, in the automatic viscous liquid constant pressure supply device, the opening and closing of the solenoid valve and the like connected to the constant pressure tank installed at the bottom of the reservoir without having a separate pump, etc. By controlling the introduction of the atmosphere, regardless of the fluctuation of the residual amount of liquid stored in the reservoir, the constant pressure tank is always kept constant, so that the liquid pressure of the liquid supplied to the outside is kept constant, By blocking contact with the liquid, it is to provide a constant-pressure constant pressure liquid supply device of a simple and sanitary structure, which also prevents the volatilization and contamination of the liquid.

In order to achieve the object of the above object, the present invention, a liquid storage tank that can seal the inlet with a stopper, and a constant pressure tank installed so that the outer periphery is maintained at the lower end of the storage tank, through the lower end of the storage tank at the upper end of the pressure vessel Connector, air inlet vent, electronic solenoid valve to open and close the vent connected to the vent, the supply port located in the lower part of the constant pressure tank to supply liquid to the outside, the solenoid valve to open and close the supply pipe connected to the supply port, The sensor which detects the liquid level of a liquid substance, etc. is provided.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 and 2 are assembled and assembled cross-sectional view according to an embodiment of the present invention.

As shown therein, the storage tank 10 is installed in the upper part of the device to receive and store the liquid product from the outside, and the injection port 12 for filling the liquid on the top and the volatilization of the liquid after the injection There is a stopper 11 to block the atmosphere.

The lower part of the upper storage tank 10 has a constant pressure tank 20 to maintain the airtight by sealing the outer portion by a method such as welding or bonding.

The top of the positive pressure tank 20 has a connector 23 installed through the bottom of the storage tank 10, so that the liquid material of the storage tank 10 is filled with the positive pressure tank 20 of the lower, the bottom of the constant pressure tank 20 When the air vent 21 is installed to a position above the lower end of the connector 23 through the upper part and supplies liquid to the outside, the solenoid valve 31v connected to the vent pipe 31 of one end of the vent hole 21 is provided. ) By opening the atmosphere into the positive pressure vessel 20 to allow atmospheric pressure to act, and through the lower end of the constant pressure vessel 20 to install the supply port 22 at the lower portion, the liquid material filled in the positive pressure vessel 20 Is supplied to the outside through the solenoid valve 32v connected to the supply pipe 32 at one end of the supply port.

At this time, the sensor 20s provided at the lower portion of the pressure vessel 20 detects the liquid level of the liquid in the pressure vessel 20 to detect whether the liquid product is sold out.

In the following, the operational relationship between the storage tank and the constant pressure tank is described in detail according to the above configuration example as follows.

When supplying the liquid stored in the reservoir to the outside, when the solenoid valve connected to the ventilator is opened, the atmosphere is introduced by atmospheric pressure, and the liquid in the reservoir is connected to the lower part of the tank through the lower end of the connector. Until it stops filling, the pressure in the empty space above the reservoir and above the constant pressure vessel equals atmospheric pressure.

Next, when the solenoid valve connected to the supply pipe is energized for a predetermined time, when the valve is opened, liquid is supplied to the outside while the inflow of the air into the reservoir and the outflow of the liquid water occur at the boundary of the bottom of the connection pipe. After a certain period of time, when the liquid water supply is completed and the two solenoid valves described above are closed, the liquid water level in the constant pressure tank is maintained at the lower end of the connecting pipe as an interface and is isolated from the outside air. Prepare for the next move.

According to the above configuration, the automatic vending machine constant pressure quantitative supply device controls the introduction and blocking of the atmosphere into the storage tank and the constant pressure tank by operating the provided solenoid valve, thereby preventing volatilization and contamination of the liquid product. Regardless of the remaining amount of the liquid stored in the reservoir, there is an effect to provide a low-cost and hygienic liquid constant pressure quantitative supply device that can maintain a constant pressure of the liquid supplied to the outside.
