Technical Field

The invention relates to electric heating cups, in particular to a safe structure of a cup cover of electric heating cups.

Background

Travel electric heating drinking cup on the existing market all has the characteristics of small diameter and high cup body, so the problem of easily falling over by accident is solved, and the electric heating drinking cup is generally divided into three types:

the electric heating water cup can not be covered with a cover (the cover has no steam hole, if the cover is covered with the cover for heating, water in the inner container can generate a large amount of steam after being heated, no place is discharged, the internal air pressure of the cup can be too high, and danger occurs), so the cover can be covered after the water is boiled and the heating is stopped, and the electric heating water cup can be put into a luggage case for travel and carry.

When the second electric heating cup is used for boiling water, a cover can be covered, a steam hole is formed in the cover, steam is discharged through the steam hole when the water is boiled, if the cup is accidentally knocked down, hot water in the cup can quickly run to a steam port, a large amount of gas can be generated when the electric heating cup is heated, the air pressure in the cup is larger than that outside, the internal steam pushes water at the steam port to be sprayed outwards, and the danger of scalding people is easily caused.

The soft silica gel plug is arranged at the steam through hole on the cover of the third electric heating water cup, when water is boiled, the silica gel plug is pulled upwards, after the water is boiled, the silica gel plug is plugged in, the lower part of the silica gel plug is provided with the reticular barb, and steam can be discharged upwards through the net.

Therefore, there is a need for improvement.

Disclosure of Invention

The invention aims to provide safe structures of the electric heating water cup cover, which have simple structure, safe use and high heating efficiency and can drink water at any time, so as to overcome the defects in the prior art.

The safety structure of the electric heating cup cover is characterized in that the cup cover assembly comprises an outer cover, a sealing plug, an outer cover fixing part, a plugging part, a support and an inner cover, the outer cover covers the top end of the outer cover, the inner cover covers the opening at the top of the inner cover, the outer cover fixing part is arranged between the outer cover and the inner cover, the support is fixed at the bottom of the outer cover fixing part, the plugging part is arranged in the support, the sealing plug is arranged in a rib position groove at the bottom of the outer cover, the periphery of the support is annularly provided with a plurality of inclined ribs, a through hole is formed between every two adjacent inclined ribs, the top of the outer cover is provided with a steam hole, the inner cover is provided with a plurality of steam through holes, the outer cover fixing part is provided with a second through hole, the steam hole is communicated with the steam through hole through a through hole, the inner part of the inner cover is communicated with the steam through hole, the periphery of the lower part of the sealing plug is mutually attached to the outer cover fixing part, when the electric heating cup, a gap is reserved between the outer cover and the sealing plug slides downwards along the inclined ribs to plug and plug the lower part of the electric heating cup.

The shape of shutoff piece and support is the toper, and the height of angularity is greater than the height of shutoff piece, and the inclination of shutoff piece is the same with the inclination of angularity, and the conical surface of shutoff piece lower part laminates with the internal surface of angularity, and the support inboard leaves the clearance with shutoff piece upper portion periphery.

An th sealing ring is arranged between the bottom of the outer cover and the top of the outer cover fixing piece, and a second sealing ring is arranged between the inner wall of the outer cover, the bottom of the outer cover fixing piece and the opening at the top of the inner container.

The support is located between inner cup and enclosing cover mounting, and the top lid of enclosing cover is equipped with the enclosing cover decoration, is equipped with between enclosing cover decoration and the enclosing cover and decorates the circle, is equipped with the communicating steam port of a plurality of and steam hole on the enclosing cover decoration.

The top outside of shell is equipped with the external screw thread, and the bottom inboard of enclosing cover is equipped with the internal thread, and the external screw thread is mutually supported with the internal thread, realizes being connected of enclosing cover and shell.

The heating device is characterized in that a heating body is arranged at the bottom of the inner container, an anti-dry heating temperature controller is arranged at the bottom of the heating body, a temperature sensor is arranged at the top of the heating body, the inner container, the heating body and the anti-dry heating temperature controller form an inner container assembly, a fixing frame is installed in the shell, and the inner container assembly is fixed on the fixing frame.

The bottom of shell is provided with the drain pan, installs touch button subassembly and control panel subassembly between drain pan and the mount, control panel subassembly includes control panel and supply socket, and supply socket fixes on the control panel, and supply socket's outside lid is equipped with the visor.

The bottom of drain pan is provided with a plurality of antiskid foot.

The blocking piece and the inner cover are made of stainless steel, and the sealing plug, the th sealing ring, the second sealing ring and the protective cover are made of rubber materials.

When the electric heating water cup is used for boiling water, water vapor generated in the cup upwards passes through the vapor through hole in the inner cover, the gap between the bracket and the periphery of the upper part of the stainless steel plugging part and the second through hole of the fixing part of the outer cover in sequence, when the vapor pressure generated in the outer cover is greater than the maximum pressure born by the sealing plug, the periphery of the lower part of the sealing plug can be jacked up by the vapor, the vapor is discharged from the joint of the periphery of the lower part of the sealing plug and the fixing part of the outer cover and then discharged through the vapor hole, and the design can prevent a large amount of heat in the cup from being dissipated during heating, improve the heating efficiency, reduce the water boiling time and; when the electric heating water cup does not work, steam cannot be generated in the cup, the periphery of the lower part of the sealing plug is attached to the outer cover fixing piece, the cup cannot leak water when being placed or loaded into a traveling bag, and the electric heating water cup is convenient to be loaded into the traveling bag for carrying when going out; after the electric heating water cup falls down, the blocking piece can slide downwards due to the action of gravity to block the second through hole of the outer cover fixing piece, so that water in the cup cannot be sprayed outwards, only a small amount of water slowly flows out of the second through hole, and the periphery of the second through hole is sealed by the sealing plug, so that the water in the cup cannot flow out; if when the work of heating up water, the cup takes place the accident and falls, continue to produce water vapor because of inside, when enclosing cover internal pressure is greater than the biggest deformability that the sealing plug can bear, the sealing plug lower part is peripheral can be backed down by steam, the lower part of sealing plug is peripheral to have steam or water to let out with enclosing cover mounting laminating department, because of having blockking of shutoff piece and sealing plug, the water or the steam that the event flows can not directly spout, only can slowly the effluence come out, the event can not take place to scald people's incident.
