Abstract

The utility model discloses an overflow-preventing large-discharge-capacity pressure relief teapot lid and relates to a teapot lid. The teapot lid is characterized in that an annular protrusion (5) is disposed on the outer periphery of the teapot lid (10), a necking-down annular cylinder (6) is disposed on the lower portion of the annular protrusion, the upper ends of at least three elastic clamp pieces (7) are fixedly connected the lower end or the lower inner face of the annular cylinder, the lower ends of at least two exhaust cylinders are fixedly connected to the upper face of the teapot lid and hinged to a self-pressure cover (2) through a shaft (1), the two exhaust cylinders form the large-discharge-capacity exhaust passages (3) of the teapot lid, and a handle (14) is disposed on the upper middle part of the teapot lid. The exhaust cylinders are used to form the exhaust passages for steam, when steam pressure in a teapot is excessively high, ascending steam presses open the self-pressure cover along the exhaust passages and discharged from the self-pressure cover, large-discharge-capacity pressure relief is achieved, and overflow can be reduced effectively.

Description

The big discharge capacity pressure release of a kind of anti-overflow lid

[technical field]

The utility model relates to a kind of lid, especially relates to a kind of kettle teapot with the big discharge capacity pressure release of anti-overflow lid.

[background technology]

Known, kettle teapot is in the process of heating up water, in case water temperature reaches or when spending near 100, be subjected to the impact of steam, be easy to make pot lid to upper punch, boiling water just overflows along teapot is suitable for reading, thereby the water that overflows is put liquefied gas out by water combustion gas is assembled in the room, just can blast in case meet naked light, produce adverse consequences; This is because due to the existing pot lid design defect, pot lid is provided with a very little relief hole, can not quick pressure releasing when water is opened, and pot lid and teapot suitable for reading between without any constraint, so steam and boiling water just can be easily with pot lid jack-up, thereby cause dangerous generation; At the existing defective of existing pot lid, be necessary that by architecture advances formation can be taken precautions against the pot lid that the spilling water phenomenon takes place and takes precautions against the security incident generation.

[utility model content]

In order to overcome the deficiency in the background technology, the utility model discloses the big discharge capacity pressure release of a kind of anti-overflow lid, utilize the aiutage that arranges on the pot lid to form the exhaust channel of steam, when water vapour pressure is excessive in kettle, the exhaust channel that up steam just can form in aiutage effluxes fast by backing down from pressure cover, realize the purpose of big discharge capacity pressure release, effectively reduced the generation of spilling water phenomenon.

For realizing above-mentioned utility model purpose, the utility model adopts following technical scheme:

The big discharge capacity pressure release of a kind of anti-overflow lid, comprise pot lid, aiutage and handle, the outer rim of described pot lid is provided with annular protrusion, is provided with the annular canister of necking down in the bottom of annular protrusion, fixedlys connected with the lower end of annular canister or lower inner face in the upper end of at least three elastic cards; The lower end of at least two aiutages is fixedly connected on the upper side of pot lid, the upper end of described at least two aiutages connects by axle and is articulated and connected from pressure cover, described at least two aiutages form the big discharge capacity pressure release exhaust channel of teapot, are provided with handle on the middle part of pot lid.

The big discharge capacity pressure release of described anti-overflow lid, inner face is provided with interior ring in the lower end of annular canister, the upper end of at least three elastic cards and described interior embedded connection of ring.

The big discharge capacity pressure release of described anti-overflow lid, the middle part of at least three described elastic cards is respectively equipped with outside arc-shaped convex, forms clamping to teapot position suitable for reading by arc-shaped convex.

The big discharge capacity pressure release of described anti-overflow lid, described aiutage are divided into down aiutage and last aiutage two joints, wherein go up aiutage be set to outward-dipping, from pressure cover connect by axle with described upward aiutage on hinged inside be connected.

The big discharge capacity pressure release of described anti-overflow lid is provided with screw rod in the bottom of handle, and described screw rod passes after the perforation that pot lid middle part arranges by nut check.

Owing to adopted technique scheme, the utlity model has following beneficial effect:

The big discharge capacity pressure release of anti-overflow described in the utility model lid, the utility model on the lid of cold water of will packing into during use, going up the elastic card that arranges by ring in the utility model is stuck on the teapot inwall suitable for reading, the effect that the utility model is subjected to elastic card when water is held can not break away from teapot, the steam that rises and hot water rise along aiutage and impact from pressure cover, the pressure relief opening of opening from pressure cover formation just makes to form in the teapot and leads to outside exhaust channel, the steam that rises effluxes via aiutage, thereby realize the pressure release of big discharge capacity, effectively guaranteed can not occur the generation of spilling water, wherein go up aiutage be made as outward-dipping, the stifling hand of steam in the time of can taking precautions against pouring; Aiutage oneself height described in the utility model also can form the stopping of spilling water, had further guaranteed effective minimizing of spilling water phenomenon, had realized the purpose that safety is heated up water.
