Further: the top is equipped with tubulose boss in the upper cup lid, the water shutoff stopper is connected with the upper cup lid through cup jointing on tubulose boss.
Further: the base is provided with a groove towards the end face of the water sealing plug, and the vent hole is communicated with the groove.
Further: the pipe wall of the tubular boss is provided with a vertically through opening.
Further: the water sealing plug is provided with an annular flange protruding inwards at the position of the free end of the tubular boss, and the annular flange is pressed on the free end face of the tubular boss.
Further: the upper part of the plunger piston at the joint of the water sealing plug is a tapered boss, and the tapered boss is matched with the base to form a clamping groove.
Further: the elastic material of the water sealing plug and the pressure balance plug is silica gel.
Advantageous effects
1. By connecting the pressure balance plug and the vent hole at the bottom of the water sealing plug, when the cup is in a negative pressure state, the negative pressure can stretch the pressure balance plug downwards due to the fact that the pressure balance plug is made of elastic materials, so that the base of the pressure balance plug is separated from the end face of the bottom of the water sealing plug, the vent hole can communicate the interior of the cup with the exterior of the cup, and the negative pressure state in the cup is eliminated;
2. the water sealing plug is sleeved through the tubular boss, so that the assembly of the water sealing plug is facilitated;
3. the wall of the boss pipe is provided with a vertically through opening, so that the air circulation between the inside of the cup and the outside of the cup is smoother when the negative pressure is eliminated;
4. the water sealing plug is provided with the annular flange at the position of the free end of the boss, so that the water sealing plug tightly leans against the water outlet under the extrusion action of the boss when the water sealing plug is pressed, water leakage during carrying is prevented, and the open end of the water sealing plug and the upper cup cover can be prevented from being tightly pressed when the water sealing plug is pressed under the force application at the annular flange, so that air flows when pressure balance is facilitated.

Detailed Description
A negative pressure adsorption-preventing cup cover comprises a cover body, wherein a cap-shaped water sealing plug 1 made of elastic materials is arranged in the cover body, the open end of the water sealing plug 1 is not in closed connection with an upper cup cover 2, the closed end is used for blocking a water outlet in the cover body, the closed end is provided with a connecting hole 11 and a vent hole 12, and as shown in figure 3, two vent holes 12 are arranged; the connecting hole 11 is internally provided with a pressure balance plug 3 made of elastic material, the pressure balance plug 3 comprises a base 32, the base 32 is provided with a plunger 31, the end face of the base 32 facing the water sealing plug 1 is provided with a groove 33, the plunger 31 faces the upper cup cover 2 and penetrates through the connecting hole 11 to be connected with the connection part of the water sealing plug 1 through a clamping groove, as shown in figure 1, the upper part of the plunger 3 at the connection part of the water sealing plug 1 is a tapered boss 34, the tapered boss 34 is matched with the base 31 to form the clamping groove, the base 32 is connected with the bottom end face of the water sealing plug 1, and the vent hole 12 is communicated; a tubular boss 4 is arranged at the top in the upper cup cover 2, a vertically through opening is arranged on the pipe wall of the tubular boss 4, and the water sealing plug 1 is connected with the upper cup cover 2 by being sleeved on the tubular boss 4; an annular flange 5 protruding inwards is arranged at the position of the water sealing plug 1, which is positioned at the free end of the tubular boss 4, and the annular flange 5 is pressed on the free end surface of the tubular boss 4; the elastic material of the water sealing plug 1 and the pressure balance plug 3 is silica gel.
When the cup is used, the upper cup cover 2 is closed, the water sealing plug 1 is pressed on the water outlet under the action of the tubular boss 4, the pressure balancing plug 3 is assembled in the connecting hole 11, the pressure balancing plug 3 is in a slight stretching state, the pressure balancing plug 3 is tightly connected with the end face of the bottom of the water sealing plug 1, the vent hole 12 is blocked at the moment, and the water cup cannot leak water; when hot water in the cup becomes cool, negative pressure is formed in the cup, the water sealing plug 1 is tightly pressed at a water outlet under the action of the negative pressure, the pressure balancing plug 3 is stretched downwards under the action of the negative pressure, when a certain state is reached, the pressure balancing plug 3 is separated from the bottom end face of the water sealing plug 1, the vent hole 12 is communicated with the inside and the outside of the cup, and because the water sealing plug 1 is not connected with the upper cup cover 2 in a closed mode, the external atmosphere can reach the inside of the water sealing plug 1 through a gap at the joint of the water sealing plug 1 and the upper cup cover 2, and then is balanced with the pressure in the cup through the vent hole 12; when the pressure in the cup is balanced, the pressure balance plug 3 rebounds, the pressure balance plug 3 and the bottom of the water sealing plug 1 recover to be in a tight connection state, and the cup is in a sealing state; if the cup cover needs to be opened, the situation that the cup cover is difficult to open due to large negative pressure in the cup can be avoided.
