Abstract

The utility model relates to an automatic overflow preventing device for electric rice pots. The phenomenon of soup water overflowing often appears in an electric rice pot at present. The existing solution is that an electric alarm unit is arranged in a pot body. The defect of arranging an electric alarm unit in a pot body is that the pressure in the pot can not automatically be released and the pressure can be released through a lid opening by people who hears the alarm. Besides, arranging an electric alarm unit in a pot body has the defects of high cost and complicated structure. The pot lid of the utility model can automatically be opened so as to achieve the purpose of preventing soup water overflowing when the pressure in the pot is super high.

Description

Automatic overflow preventing device for electrothermal pot

The utility model relates to a kind of pot for cooking rice excessive device of soup in the meal of cooking a meal that prevents.

Electric cooker has now become the more general cooker of use.But the excessive phenomenon of soup in use often appears at present.One of existing a kind of solution is: in the pot body electronic alarm device is set, in case pot inner pressure both will reach the excessive moment of soup, warning device promptly sends the sound and light alarm signal, so the people hears the news to arrive in pot cover is raised, and prevents excessive.Its shortcoming is to discharge pot inner pressure automatically, must if the people can not arrive in the very nick of time, still not reach the anti-overflow effect by listening the people who the reports to the police pressure release of uncapping.The cost of this device is very high in addition, and structure is also complicated.

Thereby the purpose of this utility model just is to provide a kind of pot cover of can opening automatically when the pot inner pressure superelevation to reach and prevent the automatic anti-overflow device of the excessive electric cooker of soup.

The purpose of this utility model is achieved in that it comprises hanging beam, gag lever post, equalizer bar, but the hanging beam front end has the hook that grapple is lived pot lid handle, end has the dependence inclined-plane, equalizer bar has inside groove, the inside is equipped with balance weight body, equalizer bar connects with hanging beam is terminal, and gag lever post places between above two beams and combines as a whole with it.Occupation mode and principle are: after pot cover covers, the hook hook of hanging beam is placed on the pot lid handle root, the preceding hook of hanging beam and terminal dependence inclined-plane prop up whole device and are placed on the pot cover like this.When pot inner pressure increases slightly in the jack-up pot cover, equalizer bar is with whole device run-off the straight, so the counterweight of the inside slips into the bottom, equalizer bar further is subjected to the counterweight effect, and whole like this device serves as that axle rotates with the position, dependence inclined-plane of hanging beam, and takes the lid of the pot off by the hook of hanging beam, when certain angle is arrived in rotation, gag lever post has been against on the pot body, prevents stopping rotation, makes pot cover raise enough big slit release pressure.

The novel advantage of this reality is an anti-overflow automatically, simple structure, and cost is low.

The utility model provides two embodiment, provide by accompanying drawing 1-9 and accompanying drawing 10-13 respectively, below in conjunction with detailed description the utility model.

Embodiment 1: referring to accompanying drawing 1-9, hanging beam be extension type (for the needs that are fit to the different size pot for it), it is socketed to form by the front-axle beam 2 and the back rest 4, the front-axle beam 2 and the back rest 4 have respectively regulates

cylindrical void

16,17, pass

cylindrical void

16,17 with screw 3, cover top nut 12 is tightened and is connected front and

rear beam

2 and 4, and front-axle beam 2 has hook 1, and the back rest 4 ends have dependence inclined-plane 5; Equalizer bar also is an extension type, it is socketed to form by main weighing apparatus beam 8 and counterweight beam 10 drawer types, form groove 15 therebetween, place in the groove 15 counterweight steel ball other balance weight body of 9(such as metal derby etc. also can) main weighing apparatus beam 8 and counterweight beam 10 follower heads all have screw, screw 11 two screw threaded engagement therewith connects, make the length of adjustable and balancing beam and groove 15, i.e. the adjustable and balancing degree; The end of the back rest 4 and main weighing apparatus beam 8 front ends and gag lever post 7 tops also are linked together with nut 13 fitted shaft with the company's of wearing screw 6, for preventing that each rod member from connecting deformation, the centre can accompany axle sleeve 14, work as hanging beam, solid shape can be tightened with screw 6 after angle adjustment is suitable in the position that equalizer bar and gag lever post 7 are mutual.

Embodiment 2 is referring to accompanying drawing 10-13.Be combined into the hanging beam (structure of similar collapsible antenna) of extension type by the front-axle beam 19 that connects together and the back rest 20, front-axle beam 19 termination buckle pawls 18, the back rest 20 bands lean on inclined-planes 26; Equalizer bar is made up of main weighing apparatus beam 23 and the counterweight beam 24 that is socketed in main weighing apparatus beam 23 rear portions movingly, and counterweight beam 24 has seal groove 25, and counterweight steel ball 9 is placed in the inside, comes the adjustment degree by mobile counterweight beam 24 on weighing beam 23 the master; Hanging beam is worked as with being linked together with 22 on screw in the back rest 20 terminal and main weighing apparatus beam 23 front ends and gag lever post 21 terminations, after equalizer bar and gag lever post 21 mutual positions and angle adjustment are suitable, screw 22 can be tightened solid shape.

More than the occupation mode of two embodiment and operating principle referring to Figure 14.

Among Figure 14, a is initial installment state; B is the momentary status of pot internal gas pressure superelevation with pot cover jack-up; C is that weighted spherical ball moves down, and makes the rotation of this device, thereby pot cover is started the state of pressure release, and this state remains to till the human intervention always.
