When the step 5) is executed, because of the arrangement of the funnel-shaped bottom wall, the water in the heat exchange chamber completely flows into the vacuum cup cover.
The implementation principle of the technical scheme of the invention is explained as follows:
in order to solve the technical problem of accurate temperature control on the premise of reducing the utilization of extra heating electric energy, the invention adopts the following technical means:
1) the cooperation of the heat transfer assembly 40 and the heat exchange assembly 20, heat collection, heat transfer and heat dissipation are not co-located
A heat exchange component 20 is arranged between the cup body component 10 and the cup cover component 30, and the heat exchange component 20 is used for heating the hot water t of the cup body0The quantitative hot water is cooled to the quantitative warm water with the given drinking water temperature. However, only with the heat exchange assembly, the heat is just easy to handle in situ, and the heat needs to be removed from the cup instead of being stored in the solid-liquid phase-change heat exchange material like the prior art, because when the solid-liquid phase-change material is full of heat, if the amount of the solid-liquid phase-change material is increased, the cup can be increased in weight, and is inconvenient to carry.
Therefore, the heat transfer assembly is designed, the heat transfer assembly utilizes the characteristics that the heat collection of the evaporation end, the heat transmission of the steam pipe and the heat dissipation of the condensation end are not in the same place, the evaporation end is arranged in the heat exchange chamber to collect the heat of quantitative hot water, the condensation end is arranged at the bottom of the cup, the fluid working medium absorbs heat at the condensation end from liquid phase to gas phase, the gaseous fluid working medium with the heat is conveyed to the condensation end at the bottom of the cup through the steam pipe, the condensation end firstly dissipates the heat to the bottom of the cup, the habit that a person can vertically place the cup after drinking water is utilized, the heat of the bottom of the cup can be dissipated to a supporting plane when the cup is placed in the upright position, and if the cup is placed on a desktop, the heat can be dissipated to the desktop from the bottom of the shell. Therefore, on the premise of not storing heat, the heat of the hot water is transferred to the cup bottom of the cup body from the heat exchange chamber, so that the heat is collected, transferred and dissipated at different places, and the heat transfer does not use electric energy.
2) The heat exchange assembly 20 is matched with the cup body assembly 10 and the cup cover assembly 30, so that gravity is utilized for guiding quantitative water when the quantitative water is vertically inverted, gravity is utilized for backflow of quantitative fluid working media of the liquid return pipe, and a fluid pump is avoided.
The heat exchange assembly is arranged between the cup body assembly and the cup cover assembly, when the vacuum cup body is vertically inverted, the vacuum cup body is arranged above the heat exchange chamber, the heat exchange chamber is arranged above the vacuum cup cover, hot water in the vacuum cup body 11 can flow into the heat exchange chamber due to gravity, and when a given liquid level is reached, quantitative hot water flows in; during evaporation, a gas pressure difference is formed between the condensation end and the evaporation end, and the steam moves along the steam pipe at a high speed. After the heat exchange is finished, the quantitative warm water in the heat exchange chamber flows into the vacuum cup cover due to gravity. And the electric energy that intelligence accuse temperature drinking cup used only is used for intelligent circuit module, specifically only is used for the intelligent circuit board of temperature sensor, level gauge, check valve and accommodation space, and its power consumption greatly reduces.
3) The vacuum cup body is sleeved with the shell, and the vacuum cup cover is sleeved with the cup cover shell, so that the temperature of the contents is accurately kept, and a containing space is provided for the heat transfer assembly and the intelligent circuit board
In the prior art, an accommodating space is provided between an inner container and an outer container of a vacuum cup body or a cup cover, the accommodating space is required to be subjected to vacuum treatment, and the accommodating space cannot be opened after a certain vacuum degree is reached. However, heat transfer components, such as the steam pipe and the liquid return pipe of the present invention, cannot be arranged on the cup cover to transfer heat to the cup bottom.
By using the vacuum cup body and the vacuum cup cover, hot water in the cup body and quantitative warm water in the cup cover can keep the temperature, and the temperature is kept when drinking at any time, so that the phenomenon that the water in the cup cover becomes cool after being vertically poured for a period of time because the cup cover is not vacuum heat insulation can be avoided.
According to the intelligent temperature control water cup based on the wireless network, on one hand, when the heat transfer assembly is vertically inverted, the liquid return pipe flows back by using gravity, steam can rise along the steam pipe to transfer heat of quantitative hot water to the bottom of the cup, on the other hand, the flowing power of the quantitative hot water utilizes the self weight of the water by using the height relation of the cup body assembly, the heat exchange assembly and the cup cover assembly in space, so that energy and noise of a fluid pump are saved, the technical situation that only heat is stored after heat exchange in the prior art is improved, the weight is reduced by 20% compared with that of a heat storage material, the power consumption is reduced by 50% compared with that of the fluid pump, and the effect is obvious.
