The present invention is further descried below in combination with <FIG>.

An error-proof operating system for a portable gas hob, comprising a gas tank cavity partition <NUM> having two ends respectively fixed to a front panel <NUM> and a back panel <NUM>, where a bounce limiting device is provided on the gas tank cavity partition <NUM>, the bounce limiting device is connected to an actuating rod <NUM>, the actuating rod <NUM> is rotatably connected to the gas tank cavity partition <NUM>, one end of the actuating rod <NUM> penetrates through the front panel <NUM>, and the top of the bounce limiting device is not lower than a bearing end <NUM> for bearing a liquid holding tray <NUM>.

The bounce limiting device comprises a pull rod <NUM> slidably connected to the gas tank cavity partition <NUM>, a gas tank driving part at the end of the pull rod <NUM> penetrates through the gas tank cavity partition <NUM> and is positioned in a gas cartridge chamber, the end of the actuating rod <NUM> is movably connected to the pull rod <NUM>, a spring a <NUM> is connected between the pull rod <NUM> and the gas tank cavity partition <NUM>, a position-limiting notch <NUM> is formed at the bottom end of the pull rod <NUM>, a position-limiting piece a <NUM> matching the position-limiting notch <NUM> is provided on a brake <NUM>, the brake <NUM> is movably connected to the gas tank cavity partition <NUM>, a spring b <NUM> is connected between the brake <NUM> and the gas tank cavity partition <NUM>, the top of the brake <NUM> is not lower than the bearing end <NUM>, the brake <NUM> is rotatably connected to the gas tank cavity partition <NUM>, a guide piece a <NUM> movable along a guide slot a <NUM> is provided on the brake <NUM>, the guide slot a <NUM> is located on the gas tank cavity partition <NUM>, and an arc-shaped surface <NUM> for reducing friction is provided at the top of the brake <NUM>. The liquid holding tray <NUM> is a square, a pressing piece <NUM> is provided at the bottom of one edge of the square, an avoidance groove <NUM> is formed at the bottom of the other three edges of the square, and the pressing piece <NUM> is in detachable contact with the arc-shaped surface <NUM>. Hob feet are fixed at four corners of the liquid holding tray <NUM>, the hob feet comprise two low hob feet <NUM> and two high hob feet <NUM>, and the two high hob feet <NUM> are located on two sides of the pressing piece <NUM>. When the liquid holding tray <NUM> is placed correctly, the pressing piece <NUM> presses against the arc-shaped surface <NUM>, and the arc-shaped surface <NUM> rotates and moves downwards to drive the entire brake <NUM> to rotate and move down, the design of the arc-shaped surface <NUM> can effectively reduce the resistance caused by the relative sliding with the pressing piece <NUM>; and the position-limiting piece a <NUM> of the brake <NUM> is separated from the position-limiting notch <NUM> on the pull rod <NUM>, and the pull rod <NUM> is released from a locked state. In this case, the pressing rod <NUM> at the end of the actuating rod <NUM> is pressed down, the actuating rod <NUM> rotates around a rivet a <NUM>, the pull rod <NUM> is pulled through the rivet b <NUM> to move in the direction of the front panel <NUM>, extending to the other end of the pull rod <NUM> in the gas tank cavity pushes the gas outlet of the gas tank in the gas tank cavity to move towards the gas inlet of the valve body, and after the gas channel is connected, the gas is supplied to the valve body and the hub burner. Two low hob feet <NUM> and two high hob feet <NUM> are provided, so that cookware such as the cooking pan <NUM> can be placed obliquely (as shown in <FIG>), thereby increasing the distance from one side of the cooking pan <NUM> to the gas tank cavity, reducing the transfer of heat from the cooking pan to the gas tank cavity, and making the hob safer to use. The high hob feet <NUM> are located on two sides of the pressing piece <NUM>, such that only when the two high hob feet <NUM> on the liquid holding tray <NUM> are both located on the proximal side of the gas tank cavity partition <NUM>, can the arc-shaped surface <NUM> at the top of the brake <NUM> be pressed down through the pressing piece <NUM> at the bottom and the pull rod <NUM> be released from the locked state; and the avoidance groove <NUM> is formed on the other three sides of the liquid holding tray <NUM>, such that the arc-shaped surface <NUM> cannot be pressed down at the three sides. As a result, only when the liquid holding tray <NUM> is placed correctly, can the gas hob be unlocked and used. After the liquid holding tray <NUM> is removed, the pressing piece <NUM> is separated from the arc-shaped surface <NUM>, and under the action of the spring a <NUM> and the spring b <NUM>, the pull rod <NUM> and the brake <NUM> are reset.
