A semiconductor refrigeration assembly includes a semiconductor refrigeration assembly, a heat-dissipation member, a cup body, and a base. The semiconductor refrigeration assembly is embedded in the bottom wall of the cup body and has an end exposed out of the cup body. The heat-dissipation member is arranged over the bottom of the cup body and abuts against the end, located outside the cup body, of the semiconductor refrigeration assembly. The base is configured to support the heat-dissipation member and to supply power to the semiconductor refrigeration assembly. The semiconductor refrigeration cup has a better heat-dissipation effect.

A manually controlled high pressure valve includes a valve body having an air inlet, an air outlet and a mounting hole; an adjusting device arranged in the mounting hole by hermetically connecting to the inside wall of the mounting hole and having an air inlet hole and an air outlet hole; a limiting block arranged below the adjusting device and matched with the adjusting device and the air inlet for controlling the air intake from the air inlet hole of the adjusting device. The limiting block can be jacked up by the high pressure of the air inlet and block off the air inlet to stop jetting outwardly when the gas is not exhausted from the air outlet of the valve; and the limiting block can be removed to form a gap between the limiting block and the inlet hole when it is required to jet outwardly.

The present invention relates to a luminous sofa cup holder comprising the cup body, the mounting base for supporting the cup body, the light source, the cooling/heating module, the temperature sensor and the control circuit for detecting the temperature of the cup body, either directly or indirectly, wherein the cup body is provided with an empty cavity, wherein the edge of the upper opening of the empty cavity is a flanging structure, which protrudes on the outer side of the cup body, wherein the light source is disposed over the outer side of the cup body; wherein the mounting base is a hollow body provided with at least one opening; wherein the cup body inserts into the mounting base through the opening provided on the mounting base; wherein the light source is held tightly by the cup body and the mounting base.

The present disclosure provides thermoelectric cooling devices, systems and methods. A thermoelectric system of the present disclosure may comprise a chamber configured to hold the beverage container; at least one actuator configured to rotate the beverage container within the chamber; a source of a thermal coupling medium in fluid communication with the chamber, wherein the thermal coupling medium is configured to thermally couple the beverage container to one or more walls of the chamber; a heat sink; and a plurality of thermoelectric cooling elements surrounding the chamber, wherein the plurality of thermoelectric cooling elements is configured to transfer heat from the beverage container to the heat sink upon application of power to the plurality of thermoelectric cooling elements, thereby cooling the beverage container.

A solar powered cooler cup is presented. The cup holds a beverage and may be transportable. The cup has a handle and a lid which allow for transport without fear of leakage or spillage. The cup also has a energy plant, a cooling segment and a heating coil. An on/off switch allows the power to be turned off when the cup is not in use. A system switch is provided that allows the switching from the cooling system to the heating system or vice versa. Further there is a charging port which may preferably be a USB port. A solar panel is coupled to the outside of the cup and provides energy for the system used to keep the beverage at a desired temperature. The solar panel may also charge the battery where the energy is stored in the plant.

A cooling drinking vessel, such as a cooling cup, with a double wall. The cooling drinking vessel includes a thermoelectric cooling mechanism which includes one or more pairs of elements from n- to p-type semiconductors with a power source, and a heat dissipation mechanism. Voltage is applied between the one or more pairs of elements from n- to p-type semiconductors to create current which passes through the one or more pairs of elements, thereby creating a cooling effect in a first side mounted to an inner part of the cooling drinking vessel to cool the content of the drinking vessel. A heat effect is created at a second side and which is dissipated by the heat dissipation mechanism.

A manually controlled high pressure valve includes a valve body having an air inlet, an air outlet and a mounting hole; an adjusting device arranged in the mounting hole by hermetically connecting to the inside wall of the mounting hole and having an air inlet hole and an air outlet hole; a limiting block arranged below the adjusting device and matched with the adjusting device and the air inlet for controlling the air intake from the air inlet hole of the adjusting device. The limiting block can be jacked up by the high pressure of the air inlet and block off the air inlet to stop jetting outwardly when the gas is not exhausted from the air outlet of the valve; and the limiting block can be removed to form a gap between the limiting block and the inlet hole when it is required to jet outwardly.

A froster system is provided that dispenses liquid CO2 from a high-pressure CO2 cylinder through a CO2-dispensing nozzle that is disposed within a refrigerator. The froster system efficiently sanitizes and chills, freezes, or ices the vessel placed at the nozzle. The froster system includes the high-pressure CO2 cylinder in fluid communication with the CO2-dispensing nozzle, cylinder-to-nozzle tubing to connect the CO2 cylinder to the CO2-dispensing nozzle, and a controller to convey the input of the user to actuate the froster system to output liquid CO2.

An actively heated drinkware container includes a vessel with a chamber that receives and holds a volume of liquid. The drinkware container includes a heating module with a first heating element operable to heat one portion of the chamber and a second heating element operable to heat another portion of the chamber, the second heating element spaced from the first heating element. Operation of the first and second heating elements generates a circulation current in the volume of liquid in the chamber that mixes the liquid and diffuses a temperature of the liquid to thereby reduce temperature stratification of the liquid in the chamber and so that a temperature of the liquid throughout the volume of liquid in the chamber is approximately uniform.
