Abstract

The utility model relates to a safety pressure cooker which is mainly composed of a cooker lid, a cooker body, a hand lever, etc. The utility model is characterized in that the cooker lid is elastically connected with the cooker body through an elastic element, and a sealing ring is flatly positioned between the cooker lid and the cooker body which are pressed tightly by means of the elastic force of the elastic element when the pressure cooker is used. When a safety pressure releasing passage of the pressure cooker is blocked or in malfunctions, high-pressure gas in the cooker can overcome the elastic force of the elastic element to push aside the cooker lid for releasing pressure, and accordingly, cooker explosion can be avoided. The utility model has the advantages of high safety and convenient operation.

Description

Safe pressure cooker

The utility model relates to a kind of pressure cooker that is used for boiling, cooking food and other purposes.

The pressure cooker that uses normally is made up of pot cover, pot body and handle at present, and safety device pressure limiting valve and fusible plug are arranged on the pot cover, and pot cover has sealing ring with pot body junction.During the working pressure pot, in certain angular alignment and screw on the pot body, a pot cover and a pot body are combined as a whole rigidly pot cover and pot body.When gas pressure reached certain value in the pot, pressure limiting valve was subjected to gas to promote to move upward, and gas is got rid of outside the pot through passage, reaches the pressure limiting purpose; When if gas pressure and temperature are too high in the pot, the fuse sheet fusing, gas is got rid of outside the pot through passage in the pot, to guarantee safety.The shortcoming of this pressure cooker is, pot cover is a kind of rigid attachment with the pot body, gas has only by pressure limiting valve or fusible plug to be got rid of, but when boiling, cooking food, pressure limiting valve and fusible plug may be stopped up by food or swill, and gas does not have other passage to get rid of in the pot, when gas pressure and temperature reach certain value, pressure cooker will be blasted, and this just now often has one of reason of pressure cooker blast.Even some producer is increased to 3～4 to the safeties on the pot cover, but still have the blocked possibility in exhaust passage, as long as pot cover is a rigid attachment with the pot body, the danger of quick-fried pot still exists.

The purpose of this utility model is to provide a kind of safe and reliable, not quick-fried pot, easy to operate pressure cooker.

In order to achieve the above object, the utility model by the following technical solutions: pressure cooker mainly is made up of pot cover, pot body and handle, and limited valve and fusible plug is characterized in that on the pot cover, and pot cover is to carry out resilient connection by flexible member with the pot body.Sealing ring is flat between pot cover and the pot body, leans on the elastic force of flexible member that a pot cover and a pot body are compressed.When emergency, the gases at high pressure in the pot overcome the elastic force of flexible member, back down the pot cover pressure release, thereby can not produce quick-fried pot.Flexible member can be arranged on the handle, also can be arranged between pot cover and the pot body, and its elastic force size is set according to actual needs.

The utility model has the advantages that: (1) safety.Because pot cover is a resilient connection with a pot body, when the safety relief channel jam or when malfunctioning, the gases at high pressure in the pot can overcome the elastic force of flexible member, back down the pot cover pressure release, and are harmless to pressure cooker, can not produce quick-fried pot.(2) easy to operate.Not needing during use pot cover and pot body only needs pot cover and sealing ring are flat on pot body in certain angular alignment, and turning handle can make pot cover and pot body close-coupled together.

Illustrate as follows:

Fig. 1 is when being arranged at flexible member on the handle, a kind of structural representation of the present utility model.

Fig. 2 be structure handle shown in Figure 1 with the A of pot body connection place to schematic diagram.

Fig. 3 is a structure shown in Figure 1, pot cover and pot body close-coupled local enlarged diagram together.

Fig. 4 is when being arranged at flexible member on the handle, another kind of structural representation of the present utility model.

Fig. 5 is when being arranged at flexible member between pot cover and the pot body, a kind of structural representation of the present utility model.

Below in conjunction with description of drawings embodiment of the present utility model:

Embodiment 1: referring to Fig. 1, Fig. 2, pressure cooker is made up of pot cover (1), pot body (2) and handle (3), and pot cover (1) is gone up limited valve (7), and fusible plug (8) has a depression bar (5) on the handle (3), and respectively there is a flexible member (4) at the depression bar two ends.When handle (3) when upwards rotating, depression bar (5) is stuck on the boss (9) of pot cover, and flexible member (4) is compressed, and pot cover (1) promptly is pressed on pot body on (2), as shown in Figure 3 tightly by depression bar (5).Sealing ring (6) is to be flat between pot cover (1) and the pot body (2), and it plays the sealing function between pot body and the pot cover.In the time will opening pot cover, as long as rotate handle (3), depression bar (5) so just can have been opened pot cover just break away from boss (9) on the pot cover (1).Embodiment 2: referring to Fig. 4, pressure cooker is made up of pot cover (1 '), pot body (2 ') and handle (3 '), and pot cover (1 ') is gone up limited valve (7 ') and fusible plug (8 '), and handle (3 ') can rotate around hinge (10).One flexible member (4 ') is arranged on the handle (3 '), and flexible member (4 ') connects with hasp (11), and pot cover (1 ') horizontal is on pot body (2 ').Seal when between pot cover (1 ') and pot body (2 '), having sealing ring (6 ') to guarantee work.During pressure cooker work, handle (3 ') upwards rotates, hasp (11) is blocked on the boss (9 ') of pot cover (1 '), rotate handle (3 ') then, flexible member (4 ') is stretched, by hasp (11), pot cover (1 ') is being pressed in a pot body (2 ') upward (shown in the right handle among Fig. 4) tightly under the effect of elastic force.In the time will opening pot cover, only need upwards turning handle (3 '), hasp (11) breaks away from boss (9 '), just can open pot cover.Embodiment 3: referring to Fig. 5, pressure cooker mainly is made up of pot cover (1 "), pot body (2 "), handle (3 "); limited valve on the pot cover (1 ") (7 ") and fusible plug (8 "), several flexible members (4 ") are installed in pot cover (1 ") lower end and a pot body (2 ") junction, and sealing ring (6 ") seals when placing between pot cover (1 ") and the pot body (2 ") with assurance work.During the working pressure pot, pot cover (1 ") is screwed on pot body (2 "), elasticity original paper (4 ") produces certain pre compressed magnitude, and pot cover (1 "), sealing ring (6 ") and pot body (2 ") just closely are linked into one.When the pressure cooker escape way occurring when blocked or malfunctioning, gas pressure promotes pot cover (1 ") in the pot, and flexible member (4 ") is further compressed, when sealing ring (6 ") and pot cover (1 ") (or pot body (2 ")) between when the gap occurring; the interior air venting of pot, guarantee pressure cooker safety.
