Technical Field

The application relates to the technical field of household appliances, in particular to a cup cover assembly and a water boiling container.

Background

The cup cover of the traditional electric heating cup only has the function of sealing the cup opening and does not have the function of pressure relief. When the electric heating water cup is used for boiling water, if the cup cover is buckled at the cup opening, the air pressure in the cup body can be gradually increased, and potential safety hazards are caused; if the cup cover is kept open when water is boiled, the time for boiling the water is long and cannot reach more than 98 ℃, meanwhile, the water is easy to overflow from the cup when the water is boiled, and the high-temperature steam of the hot water is easy to scald.

SUMMERY OF THE UTILITY MODEL

An object of the application is to provide a cup lid subassembly and container of heating up water to close the problem that the security of heating up water is low among the above-mentioned prior art of solution.

A first aspect of the present application provides a cup lid assembly comprising: the cover body and at least two breathable films. The steam-permeable cover is characterized in that the cover body is provided with an exhaust hole, a cavity is arranged in the cover body and communicated with the exhaust hole, at least two air inlets are formed in the bottom of the cavity, each steam-permeable membrane covers one air inlet and is used for blocking moisture in steam, so that gas enters the cavity through the steam-permeable membranes and is released outside through the exhaust hole.

The application provides a bowl cover subassembly through setting up two at least ventilated membranes, can enough guarantee that the ventilated membrane has higher ventilative efficiency, effectively reduces steam temperature, can guarantee again that the ventilated membrane is connected with the reliability of cavity bottom, avoids droing. Simultaneously, the cavity in the lid can realize the buffering to high-temperature gas to make high-temperature gas release to the container outside through the exhaust hole after fully cooling, the risk of scalding can not be caused to the gas through the cooling, has also released the inside pressure of container simultaneously, has realized boiling water under the condition of not opening lid subassembly, has promoted the security that this container of boiling water used.

In a possible design, a fixing groove is formed in the inner wall of the bottom of the cavity and communicated with the air inlet, and the breathable film is fixed in the fixing groove. This fixed slot can realize spacing to the ventilated membrane, prevents the ventilated membrane drunkenness, guarantees the installation reliability of ventilated membrane.

In one possible design, the cover body comprises an upper cover and a lower cover, the upper cover is buckled with the lower cover, and a heat insulation cavity is formed between the upper cover and the lower cover. The heat insulation cavity can effectively isolate high-temperature heat in the container from being transferred to the upper cover, and a user is prevented from scalding hands.

In one possible design, the cavity is formed in the lower cover, an opening is formed in the top of the cavity, a clamping groove is formed in the upper cover, and the edge of the opening is clamped in the clamping groove. This draw-in groove can realize spacing to the lower cover, prevents to take place between upper cover and the lower cover to rock.

In a possible design, the card slot further comprises a first sealing element, the first sealing element is arranged in the card slot, and the edge of the opening abuts against the first sealing element. This first sealing member can realize the sealed between cavity open-ended edge and the upper cover draw-in groove to can make cavity and thermal-insulated chamber each other not switch on, avoid the high temperature gas in the cavity to get into thermal-insulated chamber and with heat transfer to upper cover, cause the user to scald.
