Detailed Description

In order to better understand the purpose, structure and function of the present invention, the following description will be made in detail with reference to the accompanying drawings.

As shown in figure 1, the water cup of the utility model has the portable heating function, and comprises a cup body 1 and a cup cover, wherein the cup cover is buckled on the cup body 1 and is connected with the cup body 1 in a sealing way. The cup body 1 is provided with a heating mechanism which is a heating wire generally coiled in the cup body 1, and the water in the cup body 1 is heated by the heating wire.

In order to ensure that the heating pressure of the water cup rises to damage the water cup, the cup cover has a pressure relief function. The cup cover comprises a main body 2 forming the side wall of the cup cover and an end cover 3 arranged opposite to the cup opening of the cup body 1. A pressure relief cavity 4 is arranged in the end cover 3, and the cup mouth of the cup body 1 is communicated with the outer side of the end cover 3 through the pressure relief cavity 4. At least two pressure release valves 5 are arranged in the pressure release cavity 4, the set pressure of each pressure release valve 5 is gradually increased and is arranged in parallel, and therefore the pressure release valves 5 are opened in sequence to release pressure along with the gradual increase of the pressure in the cup body 1.

The lower end of the pressure relief cavity 4 is provided with an air inlet 6 communicated with the cup mouth, and an air outlet 7 extending to the outer wall of the end cover 3 is formed on the side surface. The relief valve 5 includes a valve core 51 and an elastic member, and the valve core 51 is driven by the elastic member to block the air inlet 6, so as to close the relief chamber 4. Generally, the elastic member is a spring 52, and the set pressure of the relief valve 5 is controlled by the elastic coefficient of the spring 52.

To facilitate the installation of the relief valve 5, the end cap 3 includes an inner cap 31, and an outer cap 32 located outside the inner cap 31. The bottom surface of the outer cover 32 is formed with an upper half shell 321, the top surface of the inner cover 31 is formed with a lower half shell 311, and the lower half shell 311 and the upper half shell 321 are spliced with each other to form the outer wall of the pressure relief cavity 4. The outer cover 32 has a cross rib 322 formed in the upper half shell 321, and the upper end of the spring 52 is sleeved outside the cross rib 322. The upper end of the valve core 51 forms a fixed column 511, the lower end of the spring 52 is sleeved outside the fixed column 511, and the air inlet 6 is arranged on the inner cover 31.

In order to prevent the leakage of the pressure relief chamber 4, a gasket 33 is interposed between the lower half-shell 311 and the upper half-shell 321. The gasket 33 is formed with a positioning groove 331 into which the lower half-shell end 311 is inserted. The gasket 33 is previously fixed to the lower half-shell 311 by the positioning groove 331 for easy installation.

The inner lid 31 is provided with a seal ring 8 for abutting against the peripheral wall of the cup mouth, and the inner side of the seal ring 8 is provided with a screw 9 for connecting the inner lid 31 and the outer lid 32 by a bolt.

Thus, the cup cover is screwed on the cup body 1, when the cup body 1 is heated, the two springs 52 with different elastic coefficients correspond to two different pressure relief pressures, and two pressure relief protections are formed. When the water is boiled, the air pressure in the cup rises, when the pressure in the cup rises to a first pressure relief value, the air in the cup jacks up the valve core 51, and the air is discharged out of the cup from the air outlet 7; after the air pressure in the cup is reduced to be lower than the pressure relief value, the spring 52 is reset, the valve core 51 blocks the air inlet 6, and the pressure relief valve 5 is closed, so that the cup cover is effectively sealed.

When the first pressure relief valve fails, the pressure in the cup continues to rise after reaching the first pressure relief value, and after reaching the second pressure relief value, the second pressure relief valve works. According to the requirement, the two pressure release valves can be sequentially set as the threshold value of normal water boiling, and the two pressure release valves 5 work together to accelerate the pressure release; also can be for normally boiling water the release valve with first relief valve, the second way relief valve is the safety protection valve, only blocks up the back of inefficacy when first relief valve, and the second way relief valve just can be opened, and two relief valves do not work jointly.
