The existing vehicle-mounted heating cup is disclosed in the patent (201120006054.0), which includes a cup cover (1), an inner tank (2), a shell (3), a base (4), a key frame (5), a key plate (6) and The button groove (7), the cup cover (1) is arranged on the inner tank (2), the inner tank (2) is arranged in the outer casing (3), the lower part of the outer casing (3) is arranged with a base (4), and the button holder (5 ) is arranged on the outer side of the inner liner (2), the key plate (6) is inlaid on the key frame (5), and the shell (3) is provided with a key groove (7) corresponding to the key frame (5). Its key board and main board are set separately, which is more convenient and practical, and the key board is set on the cup body, which is beneficial for the driver to operate with one hand.

However, this vehicle-mounted heating cup also has defects. For example, the cup lid lacks a safety valve, and the pressure of water vapor is too high during the heating process, causing the heating cup to be exploded by high-pressure gas, causing safety problems.

Contents of the invention

The present invention aims at the above-mentioned problems existing in the existing technology, and provides a safety cup cover in a vehicle-mounted heating cup on an automobile. The technical problem to be solved by the present invention is to prevent the vehicle-mounted heating cup from being exploded by air pressure during the heating process.

The purpose of the present invention can be achieved through the following technical solutions:

A safety cup cover in a vehicle-mounted heating cup on a car, the cup cover is cylindrical and has an inner cavity, the top surface of the cup cover is closed and the bottom surface is open, and the feature is that the cup cover includes an air Valve, the top of the cup cover is provided with a penetrating vent hole 1, and a disc-shaped fixing plate is arranged inside the cup cover, and the fixing plate and the cup cover are located in the inner cavity of the cup cover and are arranged concentrically. The edge of the fixed plate is annularly sealed and fixedly connected with the inner surface of the cup cover. The middle part of the fixed plate is provided with a through vent hole 2, and the vent hole 2 is located below the vent hole 1 and can make the cup cover The air at the bottom escapes to the outside of the top surface of the cup cover through the second vent hole and the first vent hole in turn. The air valve is fixed at the second vent hole and keeps the second vent hole in a normally closed state. At a preset value, the air valve can lead to the second air hole.

The principle is as follows: the car heating cup is heated by electric heating on the car, and a large amount of water vapor will be generated during the heating process. After the air valve is installed, the first vent hole is in the normal open state, and the fixed plate is used to support the air valve. When the air pressure is too high, the air valve can be opened, and when the air valve is opened, the vent hole 2 is in an open state, which can conduct the inside and outside of the cup cover. The water vapor opens the air valve and escapes to the outside of the cup lid, thereby preventing the heating cup from being exploded during the heating process. Since the air valve needs to be greater than the preset pressure to conduct, the heating cup will tilt due to the bumping of the car without heating Sometimes it will not make the internal liquid leak through the air valve, and it has good sealing performance and explosion-proof effect.

In the above-mentioned safety cup cover in the vehicle-mounted heating cup on the car, an annular locking groove is opened on the inner side of the cup cover, and the opening direction of the locking groove is along the axis of the cup cover toward the bottom surface of the cup cover. The edge of the fixing plate is bent toward the top of the cup cover to form a flanging, and the flanging is toward the top surface of the cup cover along the axis of the cup cover. An annular sealing ring is provided between the outer surface of the flange and the side wall of the slot, and the sealing ring respectively abuts against the outer side of the flange, the bottom surface of the slot and the side wall of the slot. After the card slot is provided, the flanging can be fixed in the card slot through the card connection function. Generally, the card connection function can be disassembled for easy replacement. The sealing ring can play a sealing role, and the gas can be released from the fixed plate. edge escapes.

In the above-mentioned safety cup cover of a vehicle-mounted heating cup on a car, the air valve includes a fixing piece, a screw, a spring and a nut, and an installation hole is opened in the middle of the fixing plate, and the middle part of the screw is inserted into the Connected in the installation hole, the top of the screw extends into the cavity between the fixing plate and the top of the cup cover, the bottom of the screw is located below the fixing plate, the top of the screw is fixed with a gasket, and the sealing The pad leans against the upper end surface of the fixed plate and closes the second air hole, the bottom of the screw has a threaded section and is screwed with the nut, and one end of the spring leans against the lower end surface of the fixed plate. The other end of the spring rests against the nut. When the inner cup body generates a large amount of water vapor during the heating process, the air pressure rises, and the high-pressure air inside the lid presses against the nut, and the high-pressure air pushes the nut to move upward, and the nut pushes the screw to move upward synchronously, and the screw compresses the spring , the top of the screw pushes away the gasket, and the gasket cannot seal the vent hole 2 after being pushed away, so that the vent hole 2 is connected, and the high-pressure gas inside the cup lid escapes through the vent hole 2 and the vent hole 1, thereby reducing the inside of the cup lid. At the same time, due to the elastic force of the spring, when the air pressure inside the cup cover is lower than the preset value, the sealing gasket will close the vent hole 2, so that the liquid inside will not leak when the heating cup is tilted. will leak.

In the above-mentioned safety cup cover of the on-board heating cup on the automobile, the spring is a helical compression spring and is sleeved on the screw. The spring is sleeved on the screw so that the directionality of the elastic force is better.

In the above-mentioned safety cup cover in the on-board heating cup of the automobile, the fixing plate, the screw and the nut are all made of stainless steel or titanium alloy. Stainless steel parts are cheap and have good corrosion resistance, while titanium alloy parts have good corrosion resistance and beautiful appearance.

In the above-mentioned safety cup cover of the vehicle-mounted heating cup on the automobile, the sealing ring and the sealing pad are silicone parts or plastic parts or rubber parts. Silicone parts are economical, good corrosion resistance, high temperature resistance, non-toxic, and good for health.

In the above-mentioned safety cup cover of the on-board heating cup on the car, the number of the two vent holes is at least two, and the two vent holes are evenly distributed along the circumference of the cup cover with the axis of the installation hole as the center, so The gasket is disc-shaped, the center of the gasket coincides with the center of the screw, and the radius of the gasket is greater than the maximum distance from the edge of the second vent hole to the center of the mounting hole. Being provided with a plurality of ventilation holes 2 is conducive to timely exhausting and preventing from being blocked, and the sealing gasket is disc-shaped and can seal the ventilation holes 2 no matter how it is rotated.

Compared with the prior art, the advantages of the present invention are as follows: the cup cover of the vehicle-mounted heating cup prevents the heating cup from being exploded during the heating process, and since the air valve needs to be greater than the preset pressure to conduct, in the case of no heating, The heating cup does not make the internal liquid leak through the air valve when the car is bumped and tilted, and the heating cup has good sealing performance and has an explosion-proof effect.
