Overflow-preventing pressure cooker

Abstract

The invention discloses an overflow-preventing pressure cooker which comprises a cooker body, a cooker cover and an exhaust pipe arranged at the upper end of the cooker cover. A pressure relief valveis arranged at the upper end of the exhaust pipe, the top of the inside of the pressure relief valve is fixedly connected with a screw, a rotary shaft is arranged in the cooker body, the upper end ofthe rotary shaft penetrates through the exhaust pipe and is in threaded connection with the screw, a first permanent magnet is arranged on the side wall, located in the cooker body, of the rotary shaft, and the side wall of the first permanent magnet is sleeved with a damping sleeve. The overflow-preventing pressure cooker is exquisite in structure, does not occupy the space of the cooker body andensures the available volume of the cooker body. By arranging a bubble eliminating needle, air bubbles are effectively prevented from overflowing, and the overflow-preventing pressure cooker is cleaner and hygienic in use. A pure mechanical structure is adopted, so that compared with the prior art, the overflow-preventing pressure cooker is safer and more stable and does not produce short circuit, circuit breakage and other potential safety hazards. Therefore, the overflow-preventing pressure cooker has longer service life. By arranging detachable stirring blades, foods can be stirred duringcooking and are prevented from being burned.

Description

technical field [0001] The invention relates to the technical field of kitchen utensils, in particular to an overflow-proof pressure cooker. Background technique [0002] Pressure cooker is also called pressure cooker, pressure cooker, is a kind of kitchen utensils. The pressure cooker uses the physical phenomenon that the boiling point of the liquid will increase at a higher pressure, and puts pressure on the water so that the water can reach a higher temperature without boiling, so as to speed up the efficiency of stewing food. It can be used to heat the cooked food to above 100°C. In high altitude areas, the pressure cooker can avoid the problem that the boiling point of water is lowered and the food is not easy to cook. [0003] The prior art is to install various exhaust valves on the air hole of the pressure cooker cover, and its structure is complicated, and it is inconvenient to scrub and maintain. In addition, there are some technologies to install a spill-proof c...

AI Technical Summary

Problems solved by technology

[0003] The existing technology is to install various exhaust valves on the air holes of the pressure cooker cover, which has a complex structure and is inconvenient for scrubbing and maintenance.

In addition, there are some technologies to install a spill-proof cover on the inside of the pot cover, but its area is too large, which not only increases the manufacturing cost, but also is inconvenient to use, and rice soup or rice grains are easy to accumulate between the spill-proof cover and the pot cover , must be cleaned in time, otherwise it will not only mildew and deteriorate, damage the lid, but also breed bacteria

Some existing technologies are to increase a sealing cover on the inner pot, and an air vent is arranged on the sealing cover. Porridge, etc., food debris is easy to get stuck in the vent hole, which not only increases the difficulty of cleaning the vent hole, but also increases the danger.
