Temperature control valve body

The present invention relates to a valve body, and more particularly to a temperature control valve body.

In order to present the flavor of the coffee, the technique of extracting the coffee essence by using ice water is accordingly produced. Generally, the iced coffee pot has an upper pot body containing ice cubes, and the ice water after dissolving the ice cubes is filled with coffee. The powder filter unit is used for low temperature extraction, and the extracted ice coffee will flow into the lower pot body for storage. During the extraction process, a valve body is usually provided between the upper pot body and the filter unit to control the ice water flow rate.

However, this kind of coffee ice drop technology needs to make a large amount of ice cubes first, and then place the ice cubes on the upper pot body to melt the ice cubes. In the process of freezing and melting, it often causes unnecessary energy loss and melts. After the ice water flows through the pipeline without the adiabatic function, it will exchange heat with the outside, and the ice water will be heated, thus reducing the cold extraction quality of the iced coffee; and the overall volume of the device is large, in handling, Very inconvenient, there are shortcomings that need to be improved.

Therefore, it is necessary to provide a novel and progressive temperature control valve body to solve the above problems.

The main object of the present invention is to provide a temperature control valve body, which has the functions of heating or cooling a liquid, and can be applied not only to an ice drip coffee device but also to a medical care industry. A device such as a drip group or a machined cutting fluid jet. The valve body has a metal valve assembly and a thermoelectric wafer unit. The metal valve assembly can be heated or cooled through the thermoelectric wafer unit, and the liquid flowing into the metal valve assembly is temperature-adjusted. For example, when the valve body is installed in the drip device, the liquid can be directly heated to the same temperature as the human body and then enter the human body to reduce discomfort.

Moreover, the valve body integrates the operating end and the temperature control device in the same space, so that the overall volume is small, and thus has the advantage of convenient replacement. For example, when used in an ice drip coffee device, no additional setting is required compared with the prior art. To accommodate the body of the ice cube, it is only necessary to set the valve body at the fluid outlet end, that is, ice water flows out.

In addition, the valve body has a metal valve assembly with a body portion covering the inside, which can avoid heat exchange between the metal valve assembly as a heat conductor and the outside, thereby wasting energy, and thus has high conversion efficiency.

To achieve the above object, the present invention provides a temperature control valve body comprising a body, a metal valve assembly and a thermoelectric wafer unit. The body has an inner space and a first inlet and a first outlet connected to the inner space; the metal valve assembly is movably disposed in the inner space, including an inlet end and an outlet end, the metal valve One end of the axial direction of the component is a closed end and is embedded in the body, and the other end is an operation end operable from outside the body to move the metal valve assembly, and the operation terminal can control the first inlet, The first outlet, the inlet end and the outlet end are connected or disconnected; the thermoelectric wafer unit has a first end and a second end disposed on one side of the body, the first end of the thermoelectric wafer unit Abutting the closed end, one of the first and second ends is a cold end and the other is a hot end.
