The air cover 51 installed in the accommodating cavity 43 covers the air outlet 411 on the inner cover 41, and only when the air pressure on the cup body 3 side is higher than that on the accommodating cavity 43 side, the air cover is pushed open by the action force of the air pressure on the higher side, so that the air outlet 411 is not covered in a sealing manner, steam escapes through the air outlet 411, is further released to the outside through the accommodating cavity 43, and the air release and the air pressure inside and outside the cup body 3 are balanced. With the structure, when only water contacts the air outlet 411 when the cup body 3 is placed upside down or transversely, water leakage can be avoided, because the internal air pressure and the external air pressure are balanced when the cup body 3 is heated positively, the air outlet 411 is smaller, and the air cover 51 covers the air outlet, the water in the cup body 3 is difficult to flow out from the air outlet 411, so that the air is ventilated and does not leak water.

As a preferred embodiment of the present application for enhancing air and water permeability, the air-permeable and water-leaking device further comprises a receiving base, the receiving base comprises a cylindrical ring base 52, an annular clamping portion 521 with a through hole protrudes inwards from the inner side of the ring base 52, the ring base 52 surrounds the air cover 51 with a gap, an elastic member 53 is arranged between the air cover 51 and the clamping portion, and the air cover 51 is elastically pressed above the air outlet 411.

In this embodiment, through dividing the circuit board into two, each components and parts in the rational arrangement base have reached the effect of avoiding the circuit board to become the main factor that restricts the base volume, can save the space in the base for the volume of electric heat cup base 2 is more reasonable. The circuit board of the electric heating cup is divided into two parts, the first circuit board 84, namely the power supply circuit board, is mainly used for controlling related to a power supply, and the components arranged on the first circuit board are mainly capacitors, resistors and the like, so that the electric heating cup can be connected to the power supply more safely and stably; the second circuit board 85, i.e., the main circuit board, is mainly used for controlling and functioning other functions, such as overheat temperature control and temperature display, and implementing a complete machine switch by combining with a switch structure. The two circuit boards are in work division and cooperation and are electrically connected, signal interaction between the two circuit boards cannot be influenced, and all functions of a common single circuit board can be realized. The limit of the size of the circuit board integrating multiple control functions to the whole volume of the base is weakened, and the arrangement among all components in the base 2 can be more reasonable, so that the volume of the base can be reduced as much as possible, and more space is reserved for containing more water for the cup body.

And the existence of cooling space 16 is the space of saving under the prerequisite of reasonable setting circuit board and other parts, and in the production reality, the relation between its specific volume size and the heat dissipation through reasonable trade-off of technical staff in the art to can not make the volume of base bigger than current product.

Importantly, because the water in the electric heating cup is not required to be manually opened, and the space saved by combining the base is more suitable for carrying, the electric heating cup is particularly suitable for being used in places which are inconvenient to use such as a vehicle, and the like, and the simple and easy-to-use degree of the portable use is improved.

In addition, the protective sheath 13 can prevent physical damage from the outside. The protective sleeve 13 is a part which adds protection to the power line slot exposed outside, and can protect the power line slot 12 from the outside when the power line is not required to be plugged. This is the use scene of having considered portable electric heat cup mainly, because at the in-process of carrying, electric heat cup is put in same case and bag with other article very easily, for example sharp-pointed article such as key stab into power cord slot easily, cause the power cord slot to damage, also can avoid the foreign matter to fill in the power cord slot, cause contact failure, further influence the use of whole electric heat cup.
