Abstract

The utility model relates to the technical field of pressure cookers, particularly a pressure limiting valve of the pressure cooker, which comprises a valve body, a lifting handle, a thimble and an exhaust pipe, wherein the lifting handle is sheathed outside the valve body; the valve body is provided with a through cavity; the through cavity is communicated with an air discharge hole by the lifting handle; the upper end of the exhaust pipe is inserted and sheathed in the through cavity from the bottom of the through cavity; the valve and/or the lifting handle on the upper end of the exhaust pipe in the through cavity is provided with a region for containing the thimble; the upper end of the thimble is inserted and sheathed in the region; the lower end of the thimble is inserted in an opening on the upper end of the exhaust pipe in the through cavity; a buckling device is arranged between the inner wall of the lifting handle and the corresponding outer wall of the valve body; the buckling device can lead the lifting handle to be buckled with the valve body together. The thimble, the valve body and the lifting handle are mutually buckled so as not to disengage caused by expansion. The utility model extends the service life.

Description

The pressure limiting valve of pressure cooker

Technical field

The utility model relates to a kind of pressure cooker technical field, specifically is a kind of pressure limiting valve of pressure cooker.

Background technology

The present auto-electronic pressure cooker of selling on the market, be equipped with pressure limiting valve on its pot cover, country has announced that the utility model name is called the improvement structure of limiting valve of pressure cooker, the patent No. is ZL03247947.6, its structure is: comprise valve body, place the jump ring of valve hole bottom, sleeve is in the spool of valve hole, clog the thimble of valve core through hole, pressure limiting valve seat and anti-blocking seat are formed, its valve body places in the cavity of a handle, be right after an end of thimble in the cavity of this handle, the other end of thimble stretches into valve hole and fills in the upper end of valve core through hole, the handle sleeve is in the pressure limiting valve seat, it inserts pressure limiting valve seat lower end partly and has several high breach and the low breach that is differential arrangement, be provided with in the pressure limiting valve seat and described high breach and the suitable projection of low breach, high breach and low breach are located on the opening perisporium of handle lower end, high breach and low mouth are curved, between adjacent two breach a certain distance is arranged, projection is the some projections that are horizontal protrusion in the pressure limiting valve seat, protruding distance apart from pressure limiting valve seat bottom is identical, the handle sleeve is printed on the outer surface of pressure limiting valve seat and shows the exhaust condition sign, jump ring is the sheet piece that is " Ω " shape, spool passes the jump ring through hole and is clipped in this jump ring through hole, there is portion the lower end of valve hole, and jump ring is installed on the position of this recess.

The limiting valve of pressure cooker of said structure has the following disadvantages: 1), after handle expanded, place the thimble in the handle cavity to break away from easily, the build-up of pressure pot can not seal and can not produce pressure, has shortened the service life of product.2), behind the handle expanded by heating, handle and valve body break away from, valve body is hot, can not directly touch with hand carry out artificial exhaust, loses the due function of pressure limiting pot.

The utility model content

The purpose of this utility model is to solve above-mentioned shortcoming, and provides a kind of handle and thimble of preventing to break away from the pressure limiting valve of the pressure cooker of valve body.

For achieving the above object: include valve body, be sheathed on valve body outer handle, thimble and blast pipe, valve body is provided with cavity, cavity is connected with bleeder port on the handle, described blast pipe upper end is gone in the cavity by cavity bottom sleeve, the interval that the valve body of its described cavity inside exhaust pipe upper end and/or handle are provided with ccontaining thimble, thimble upper end sleeve is gone in the interval, the upper end open of cavity inside exhaust pipe is filled in its lower end, is provided with between described handle inwall and the corresponding valve outer wall to make it anchor together button bit device mutually.

Described interval is through hole or the groove that is provided with on the valve body of blast pipe upper end.

The lower end at described handle top has protuberance, and protuberance inserts valve body cavity top, and the position of corresponding blast pipe upper end is provided with the interval of ccontaining thimble on the protuberance, and described interval is a groove.

Its circumferencial direction of inwall upper edge of described handle is provided with a plurality of protuberances, and the position of corresponding each protuberance is provided with recess on the valve outer wall, and described protuberance and recess constitute the button bit device.

The beneficial effects of the utility model: 1, thimble, valve body, handle fasten mutually, and it is not subject to expand and breaks away from, and increases the service life.
