Self-heating-type pressure cooker

Abstract

The invention provides a self-heating-type pressure cooker. The self-heating-type pressure cooker comprises an inner cooker body and an outer cooker body. An upper handle is arranged on the inner cooker body, a lower handle is arranged on the outer cooker body, and a heating packet is arranged in the space between the inner cooker body and the outer cooker body. A self-lock valve is arranged in the lower handle, the self-locking valve comprises a valve seat, a valve element, a lock rod and a lock rod seat, the valve element is arranged in the valve seat in a sleeved mode and can move in a reciprocating mode, the lock rod is fixed onto the lock rod seat, the lock rod seat is fixed to the rear end of the valve element, a spring is fixed in the lower handle, an ejector rod is arranged on the upper handle, a lock groove is formed in the ejector rod, a one-way sliding groove is formed in the lower handle, and when the inner cooker body and the outer cooker body are matched in place, the upper handle and the lower handle coincide and the ejector rod is located in the one-way sliding groove. The self-heating-type pressure cooker can generate heat automatically, and is convenient to carry and use; the radial self-locking valve is arranged on the lower handle, after the pressure cooker is closed in place, the self-locking valve enables the upper handle and the lower handle to be locked in position, and therefore opening safety is guaranteed; when the pressure cooker is not closed in place, the self-locking valve automatically releases pressure to guarantee the closing safety, and therefore the potential safety hazards of opening and closing of the pressure cooker are eliminated.

Description

technical field [0001] The invention relates to a self-heating pressure cooker. Background technique [0002] The stainless steel pressure cooker of the prior art mainly consists of a pot body, a pot cover, a sealing ring, a pressure limiting valve, a self-locking structure, a handle, etc., and generally all uses an electric heat source or a gas heat source during heating. When eating, there is no power supply, and a gas heat source must be brought, which will cause inconvenience, so the work is subject to certain geographical limitations. At present, there are also self-heating pressure cookers on the market, which are composed of inner and outer pots, sealing rings, locking parts, pressure limiting valves, safety valves, handles, etc. There is a certain space in the inner and outer pots. A medicine heating pack is placed, the inner and outer pots are locked by locking parts, and the medicine is heated through the reaction to generate temperature to cook the food in the in...
