Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Referring to fig. 1-2, a self-power-off type heat preservation pot comprises a pot body 1, wherein a movable plug 2 is closely attached to the inner side wall of the pot body 1, the movable plug 2 is made of silicon-aluminum alloy, the silicon-aluminum alloy is low in density and light in whole and is a good material for a piston, the piston made of the silicon-aluminum alloy is good in sealing performance and high in flexibility, the piston is low in friction with the inner wall of the pot body 1 and cannot be easily blocked, and a circular truncated cone-shaped sliding slope is formed in the bottom of the movable plug 2, so that food in the pot body 1 can be poured out conveniently.

Seted up fixed mouthful on the roof of activity stopper 2, the sealing opening has been seted up on the inside diapire of fixed mouthful, set sealing plug 3 in the sealing opening, glass lid 4 is installed on the top of sealing plug 3, also set up the through-hole on the sealing plug 3, can observe the food situation of the internal portion of pot through glass lid 4, set up the operation mouth 5 of mutually supporting with glass lid 4 on the roof of the pot body 1, set up screw thread on the lateral wall of glass lid 4 bottom, set up the screw thread with 4 intermeshing of glass lid on the inside wall of fixed mouthful, when fixed glass lid 4, fill in sealing plug 3 in the sealing opening earlier, then rotatory glass lid 4, glass lid 4 realizes the fixed to glass lid 4 with fixed mouthful screw-thread engagement, the inside gas tightness of the pot body 1 has been guaranteed simultaneously, gas can not reveal through glass lid 4.

Install hot plate 8 in the diapire of the pot body 1, heating port 7 has been seted up on the diapire of the pot body 1 inside, the internally mounted of heating port 7 has hot plate 8, hot plate 8 adopts comparatively ripe PTC heater, heat the heat preservation to the food of the pot body 1 inside, the inside wall facing of the pot body 1 is equipped with stainless steel inner bag 6, and stainless steel inner bag 6 is sealed with heating port 7, stainless steel inner bag 6 preserves food more sanitary, lower with the coefficient of friction of activity stopper 2 simultaneously, durability and life are all higher.

The activity groove 9 has been seted up on the inside wall of the one side of the pot body 1, the pole hole 10 has been seted up to the inside cavity of activity groove 9, install connecting rod 11 on the lateral wall of activity stopper 2, and connecting rod 11 is located pole hole 10, first contact block 12 is installed to the bottom of connecting rod 11, install spring 13 on the diapire of pole hole 10 inside, second contact block 14 is installed on the top of spring 13, the both ends of hot plate 8 are connected with first electric wire 15 and second electric wire 16 with first contact block 12 and second contact block 14 electricity respectively.

When the temperature of the 1 inside of the pot body is too high, the 1 inside air of the pot body is heated and expanded, glass lid 4 is by jack-up together with activity stopper 2, consequently connecting rod 11 drives first contact block 12 and moves up, first contact block 12 and the separation of second contact block 14, the circuit disconnection, heating plate 8 stop heating, food in the pot body 1 reduces because heat-conducting temperature gradually, the gas volume shrink, glass lid 4 falls down again together with activity stopper 2, and first contact block 12 and the second contact block 14 contact again, the circuit realizes switching on, heating plate 8 heats once more, so reciprocal can realize the heat preservation to food, and the security is higher.

An annular bulge is arranged on the stainless steel inner container 6, and the movable plug 2 is positioned on the upper side of the annular bulge. The movable plug 2 is prevented from falling off, the movable plug 2 is limited between the annular bulge and the pot top, the movable groove 9 is always sealed by the movable plug 2, gas in the pot cannot enter the rod hole 10 through the movable groove 9, and therefore the height of the outer wall of the movable plug 2 needs to be made large enough.

The bottom wall of the pot body 1 is internally provided with a rechargeable lithium battery, the first contact block 12 and the second contact block 14 are respectively electrically connected with two stages of the rechargeable lithium battery, as a common means, the rechargeable lithium battery is arranged in the pot body 1 to supply power to the heating plate 8 and charge the battery, and the heating plate 8 works discontinuously, and the power consumed by heat preservation is small, so that the battery can be used for a long time, and the heat preservation time is prolonged.

Although the terms pot 1, movable plug 2, sealing plug 3, glass cover 4, operation opening 5, stainless steel inner container 6, heating opening 7, heating plate 8, movable groove 9, rod hole 10, connecting rod 11, first contact block 12, spring 13, second contact block 14, first wire 15, second wire 16, etc. are used more herein, the possibility of using other terms is not excluded.
