Double-layer cooling vacuum cup capable of effectively preventing negative pressure effect

Abstract

The double-layer cooling vacuum cup capable of effectively preventing the negative pressure effect comprises a cup body, an inner container layer is installed on the inner side of the cup body, a driving motor is installed on the bottom wall of the outer side of the inner container layer and located on the inner side of the cup body, and a rotating rod is installed at the output end of the driving motor and penetrates through the bottom wall of the inner container layer. A stirring rod is installed on the outer side of the rotating rod, a detachable base is installed on the outer side of the bottom of the cup body, an embedding groove is formed in the inner side of the top of the base, and the bottom of the cup body is located on the inner side of the embedding groove. The stirring rods are installed, the driving motor operates to drive the rotating rod at the output end to rotate, the rotating rod rotates to drive the stirring rod on the outer side to rotate, the stirring rod rotates to enable water to rotate on the inner side of the inner container layer, and the heat loss speed in the water is increased through rotation of the water; and the water below can move to the upper part to release heat.

Description

technical field [0001] The invention relates to the technical field of thermos cups, in particular to a double-layer cooling thermos cup that can effectively prevent the effect of negative pressure. Background technique [0002] In various environments such as home, office, and class in daily life, especially for office workers and students, in order to drink water at a suitable temperature, a thermos cup is often used. When the user is thirsty, because the temperature is too high, he cannot drink the water and needs to wait until the water cools down before drinking, which is a waste of time. [0003] The defective that the cooling thermos cup exists in the prior art is: [0004] 1. Patent document CN207949553U discloses a thermos cup that is convenient for brewing medicine, "comprising: a thermos cup shell, a thermos cup liner is provided inside the thermos cup shell, and a thermos cup liner is provided between the thermos cup liner and the thermos cup shell. There is a ...

[0004] 1. Patent document CN207949553U discloses a thermos cup that is convenient for brewing medicine, "comprising: a thermos cup shell, a thermos cup liner is provided inside the thermos cup shell, and a thermos cup liner is provided between the thermos cup liner and the thermos cup shell. There is a honeycomb heat transfer skeleton, a thermos cup cover, a stirring rod is provided in the middle part of the lower side of the thermos cup cover, a telescopic rod is sleeved on the lower part of the stirring rod, a stirring shaft is horizontally provided at the front end of the telescopic rod, and a heat preservation base is arranged. The upper part of the installation groove is provided with a medical silicone protection ring, the inside of the installation groove is provided with a medicine box through the connecting thread, and the outside of the bottom of the medicine box is provided with a sealing gasket that matches the bottom of the installation groove; the inside of the honeycomb heat transfer skeleton is filled with corresponding The temperature-changing filling is convenient for drinking medicine granules in time. The front end of the telescopic rod is horizontally equipped with a stirring shaft, which is convenient for drug stirring. There is a sealing gasket to prevent the medicine inside the medicine box from being damp." The device lacks an auxiliary heat dissipation structure, and the water remains still in the water cup, which cannot quickly realize the heat dissipation of the water

[0005] 2. The patent document CN211432088U discloses a thermos cup, "including a thermos cup body, a thermos cup cover, a pusher, a sealing ring and a driving part; the driving part is installed at the upper end of the thermos cup cover, and the pusher is installed at the lower end ; The upper end of the pusher is provided with at least one push rod, and the push rod moves through the thermos cup cover to connect with the drive part; the sealing ring is arranged between the thermos cup cover and the pusher; , the pusher is located in the mouth of the cup; a gap is formed between the inner wall of the mouth of the cup and the pusher, and the sealing ring is located in the gap; the driving member is pulled to drive the pusher to move upward, and the gap is narrowed and sealed The ring is full, so that the thermos cup cover is sealed with the cup mouth; the driving part is pulled to drive the pusher to move downward, and the sealing ring is elastically reset, breaking the sealed connection with the inner wall of the cup mouth of the thermos cup body; it is opened or closed by the above method The lid of the thermos cup is very convenient, and the thermos cup is well sealed." This device lacks a structure to accelerate the temperature drop in the water. When the water is still, the heat dissipation speed of the water is slow

[0006] 3. The patent document CN209300699U discloses a double-layer thermos cup including a cup body and a cup cover, "including an insulation layer and a heat dissipation layer. The insulation layer is embedded in the heat dissipation layer. The cup wall and the sealed thermos cup bottom, the heat dissipation layer includes the heat dissipation cup bottom, the heat dissipation cup wall and the heat dissipation cup mouth from top to bottom. Below the bottom, the bottom of the heat dissipation cup is sealed and wrapped at the junction of the thermos cup mouth and the thermos cup wall; the junction of the thermos cup wall and the thermos cup mouth is provided with a hot water outlet, and the hot water outlet is connected to the insulation layer and the heat dissipation layer; There is a valve at the water pouring outlet, the valve includes a control end and a working end, the working end is embedded on the wall of the thermos cup and blocks the hot water pouring outlet, the control end is located outside the bottom of the thermos cup wall and the heat dissipation cup; the cup cover includes the thermos cup cover and cooling cup cover, the insulation cup cover is screwed on the insulation cup mouth, and the heat dissipation cup cover is screwed on the heat dissipation cup mouth.” The device lacks a structure to assist in judging the water temperature, and the user cannot accurately control the water temperature

Reasonable structure and good thermal insulation performance”, the traditional thermos cup cannot maintain the heat after heat dissipation, the heat loss is faster, and the thermal insulation effect is lost
