Description

TECHNICAL FIELD

[0001] The utility model relates to pressure cooker technical field, concretely relates to a pressure cooker with overflow protection structure. BACKGROUND

[0002] The working principle of pressure cooker is based on the physical characteristics that the boiling point of water is affected by air pressure. Under standard atmospheric pressure, the boiling point of water is about 100 DEG C. The pressure cooker raises the air pressure in the pot through the sealing structure, thereby increasing the boiling point of water. Generally, the air pressure in the pressure cooker can reach 1.5 atmospheric pressure or even higher, and the boiling point of water will also be increased to more than 110 DEG C. In this way, a high-temperature and high-pressure environment is formed inside the pressure cooker, which can cook food faster.

[0003] The utility model discloses a pressure cooker of CN205144302U, including the lid and the inner chamber of being equipped with the inner pot and the pressure relief cavity of being arranged independently to the inner pot, is equipped with the pressure relief valve of being able to discharge to atmosphere on the pressure relief cavity, is equipped with the pressure relief switch between the pressure relief cavity and the inner chamber, make the pressurized gas in the inner chamber can be discharged into the pressure relief cavity through the pressure relief switch, in turn through the pressure relief valve and discharge.

[0004] When the active pressure relief occurs, the high-pressure gas often brings liquid to spray, and the spraying in all directions can cause the user's high-temperature scalding and also cause the liquid to splash in all directions. UTILITY MODEL CONTENTS

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical scheme and advantages of the utility model more clear, the technical scheme of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope protected by the utility model.

[0024] Referring to Figures 1-4 As shown in the utility model provides a kind of with overflow protection structure's pressure cooker, including pot body 1 and pot cover 2, pot body 1 and pot cover 2 are made of composite steel material, the upper portion both sides of pot body 1 is provided with handle 8. Pot cover 2 is provided with hand self-contained pressure relief valve 5, hand self-contained pressure relief valve 5 place can detachably be provided with overflow container 6 that can block and collect gas-liquid overflow at the place.

[0025] As shown in the utility model provides a kind of with overflow protection structure's pressure cooker, including pot body 1 and pot cover 2, pot body 1 and pot cover 2 are made of composite steel material, the upper portion both sides of pot body 1 is provided with handle 8. Pot cover 2 is provided with hand self-contained pressure relief valve 5, hand self-contained pressure relief valve 5 place can detachably be provided with overflow container 6 that can block and collect gas-liquid overflow at the place. Figure 1 And 2 As shown in the utility model provides a kind of with overflow protection structure's pressure cooker, including pot body 1 and pot cover 2, pot body 1 and pot cover 2 are made of composite steel material, the upper portion both sides of pot body 1 is provided with handle 8. Pot cover 2 is provided with hand self-contained pressure relief valve 5, hand self-contained pressure relief valve 5 place can detachably be provided with overflow container 6 that can block and collect gas-liquid overflow at the place.

[0026] Pot cover 2 is provided with the first valve hole for installing hand self-contained pressure relief valve 5, and the bottom end of hand self-contained pressure relief valve 5 passes through the first valve hole and is connected with inner sleeve cover 9. Inner sleeve cover 9 can realize the installation and fixation of hand self-contained pressure relief valve 5 in the first valve hole, and inner sleeve cover 9 is fixed at the end hole of the first valve hole in a sealing adhesion and welding mode.

[0027] Pot cover 2 is provided with two passive safety valves 11, and passive safety valve 11 is made of rubber material. Through the above specific structure design, passive safety valve is a pure mechanical safety device, which is automatically triggered to close the valve of medium flow when the pressure or temperature exceeds the safety specified value through certain mechanical principle.

[0028] Pot cover 2 is provided with pressure handle 3 above two passive safety valves 11, and pressure handle 3 is provided with handle 4. When the pressure or temperature exceeds the safety specified value, passive safety valve 11 is sprayed at high pressure, so as to release pressure from the hole, and at this time, pressure handle 3 can block passive safety valve 11 sprayed, to avoid damage caused by high-pressure ejection of passive safety valve 11.
