Abstract

The invention provides a pot cover capable of being automatically pushed open by steam, relating to the technical field of the household kitchen in daily life, in particular to a pot cover capable of being automatically opened and closed along with steam. The pot cover is composed of a pot cover ring, four movable petals, a handle, a pot cover support and a spring hinge. The pot cover is characterized in that the four movable petals can be automatically blown and pushed open by steam of 100 DEG C of food (such as water, gruel, dishes and the like) in a pot, so that the steam is exhausted and the food is prevented from overflowing out of the pot.

Description

Steam is washed pot cover automatically open

Technical field

The present invention relates to household kitchen daily life sciemtifec and technical sphere, refer in particular to a kind of pot cover that has with the automatic folding function of steam.

Background technology

The kitchen pot cover all is an overall structure at present, all is with the pot cover cap during use.It is taken away when being about to boil when food in the pot (water, congee, dish etc.), overflow outside the pot to avoid food.So relatively waste of manpower and time, particularly when cooking food with pot always the someone nurse, can not leave, overflow pot otherwise very easily cause.

Summary of the invention

Technical program of the present invention lies in realizing with pot cover circle, movable block lobe, handle, pot cover support and spring hinge.

Under the normal condition, the movable block lobe is in the overlap joint closed condition with the pot cover support under the spring hinge effect; When this pot cover food in pot is about to boil (water, congee, dish etc.), will produce 100 ℃ of high-temperature steams and upwards blow and dash, and four movable block lobe one ends are overlapped on the pot cover support with the other end by spring hinge is fixing, being subjected to high-temperature steam blows and dashes, thereby the movable block lobe is opened, avoided food to overflow.Need under the longer situation when the time of cooking congee, the movable block lobe is opened sustainable maintenance; When temperature lowered, under the spring hinge effect, the movable block lobe can automatically reset and close.

The invention has the advantages that and save the manpower time, avoid the pot that overflows when cooking.

Description of drawings

Fig. 2 is the vertical view of this pot cover.

Fig. 3 is the structure chart of spring hinge.

The specific embodiment

Shown in the elevation cross-sectional view of this pot cover among Fig. 1, a kind of pot cover that has with steam folding function comprises pot cover circle [1], movable block lobe [2], handle [3], pot cover support [4] and spring hinge [5].

Pot cover circle [1] is positioned at the pot cover bottom, and with pot cover support [4] one, handle [3] is embedded in the positive center of pot cover support.Four movable block lobes [2] link with pot cover circle [1] respectively by spring hinge [5].Left profile represented that one of them movable block lobe [2] of this pot cover sweeps away situation about opening blowing of steam gas, and right section has then been represented movable block lobe [2], and this rides over closed condition on the pot cover support.

The vertical view of this pot cover has represented that four movable block lobes [2] reach and the concrete on-link mode (OLM) of pot cover circle [1] among Fig. 2.Each movable block lobe [2] is fixing with two spring hinges [5], and movable block lobe [2] blows at gas and sweep away and can rotate around the fixed axis of spring hinge [5], reaches the purpose of unlatching.

Shown in the structure chart of this pot cover spring hinge [5] among Fig. 3, hinge [6] and hinge [9] respectively with Fig. 1, Fig. 2 in movable block lobe [2] and pot cover circle [1] link, can rotate around hinge [8] after the link.Torsion spring [7] is set on the hinge [8], and under the effect of torsion spring elastic force, movable block lobe [2] rides on the pot cover support [4], plays sealing function under the normal condition.When steam in the pot reaches uniform temperature (as 100 ℃ time), steam produces overcomes torsion spring elastic force to upthrust four movable block lobes [2] is opened, thereby avoids pot interior food to overflow.

Claims

1. a steam is washed pot cover automatically open; Form by pot cover circle, four movable block lobes, handle, pot cover support, spring hinges.This pot cover 100 ℃ of steam of food (water, congee, dish etc.) in pot blow and sweep away, and can automatically four movable block lobes be opened, and let off steam, and avoid food to overflow outside the pot.

2. wash pot cover automatically open by the described steam of claim 1, it is characterized in that: when this pot cover food in pot is about to boil (water, congee, dish etc.), will produce 100 ℃ of high-temperature steams and upwards blow and dash, and four movable block lobes are fixed on above the pot cover circle by spring hinge, being subjected to high-temperature steam blows and dashes, thereby the movable block lobe is opened, avoided food to overflow.Need under the longer situation when the time of cooking congee, the movable block lobe is opened sustainable maintenance; When temperature lowered, under the spring hinge effect, the movable block lobe can automatically reset and close.
