Specifically, the depth h of the heat generating plate 22 cannot be too small to ensure a certain pulverizing effect; the depth H of the hotplate 22 must not be so great as to cause a reduction in the height of the upper inner glass 21 (with H unchanged), which affects the visualization.

Further, turbulence ribs may be provided on the inner side walls of the inner glass 21 and/or the heating plate 22 to enhance the material pulverizing effect.

Further, the double-layered cup is prone to the following problems when in use: when the cup body just finishes making hot drink, if the user washs the cup body immediately at this moment, can lead to the cup body to cool down sharply, the air contraction in the sealed chamber between inside and outside cup leads to inside and outside pressure differential increase, outside pressure is obviously more than inside pressure, and the washing water gets into the sealed chamber through the weakest position of the sealed of rim of a cup sealing washer and/or bottom of a cup sealing washer this moment easily, and will produce steam in the sealed chamber when making hot drink next time, causes sealed intracavity to form fog and water droplet, influences user experience. Meanwhile, in the process of continuously expanding with heat and contracting with cold of the sealing cavity, acting force is continuously applied to the sealing ring, so that deformation and failure of the sealing ring are easily accelerated, and the service life of the sealing ring is shortened. Moreover, if the sealing rings between the inner cup and the outer cup are too tight and are easy to deform, the sealing is insufficient, water is easy to enter the sealing cavity, and high sealing requirements are provided for the sealing structure.

To solve the above problem, the present application may further provide a pressure adjusting device (not shown) by which the pressure in the insulating interlayer 24 can be adjusted to balance the internal and external pressure differences of the insulating interlayer 24 when the pressure in the insulating interlayer 24 is changed. On one hand, the sealing requirement of the inner and outer cup sealing structure can be reduced, the use reliability of the inner and outer cup sealing structure is ensured, and the service life of the inner and outer cup sealing structure is prolonged; on the other hand, the water can be prevented from entering the isolation interlayer 24, and the air in the isolation interlayer 24 is prevented from continuously expanding with heat and contracting with cold to influence the sealing effect and the visual effect.

The pressure regulating device is provided in the cup housing 23. Preferably, a shielding member is arranged outside the cup shell 23, and is arranged between the upper end sealing structure and the lower end sealing structure of the inner cup and the outer cup, and the pressure adjusting device is arranged inside the shielding member. By providing the pressure regulating device hidden, water ingress into the insulating interlayer 24 is further prevented.

The pressure regulating device is any one of a waterproof breathable film, a one-way valve, a silica gel plug or a siphon pipe, for example. For example, when the pressure adjusting device is a one-way valve, when the food processor just finishes making hot drinks, if a user immediately cleans the cup body, when the pressure difference between the inside and the outside of the isolation interlayer 24 exists, the outside air can push up the one-way valve under the action of the pressure difference, the pressure difference between the inside and the outside of the isolation interlayer 24 can be balanced through ventilation, and meanwhile, liquid can be prevented from entering the isolation interlayer 24. When the pressure regulating device adopts other structures, the working principle is similar, and the detailed description of the pressure regulating device is omitted here.
