Exhaust assembly, upper cover assembly, and cooking device

An upper cover assembly, comprising:

• an upper cover;
• and
• an upper cover;
• and
• an exhaust assembly, comprising,
• an exhaust system, configured to be opened and closed;
• an exhaust trigger member, connected to the exhaust system and adapted to trigger the exhaust system to open,
• a reset trigger member, connected to the exhaust system and adapted to trigger the exhaust system to close;
• and
• a toggle member, adapted to move between an exhaust position and a closing position, wherein in the exhaust position, the toggle member acts on the exhaust trigger member and causes the exhaust trigger member to trigger the exhaust system to open, and in the closing position, the toggle member acts on the reset trigger member and causes the reset trigger member to trigger the exhaust system to close, disposed on the upper cover;
• wherein the exhaust system comprises:
• an exhaust apparatus, the toggle member causing, in the exhaust position, the exhaust trigger member to trigger the exhaust apparatus to open;
• and
• a self-locking member, adapted to the exhaust trigger member and the reset trigger member, wherein the self-locking member is configured to be in a limiting fit with the exhaust trigger member to maintain the exhaust apparatus open, and when triggered by the reset trigger member, the self-locking member is released from the limiting fit with the exhaust trigger member, wherein the self-locking member comprises:
• an exhaust slider, adapted to slide between a first position and a second position and configured to be in a limiting fit the exhaust trigger member in the first position;
• and
• a slider elastic member, connected to the exhaust slider, wherein in the second position, an exhaust slider is released from the limiting fit with the exhaust trigger member and causes the slider elastic member to be compressed, and elastic restoring of the slider elastic member causes the exhaust slider to reach the first position, wherein
• the self-locking member is provided with a first engagement portion, the exhaust trigger member is provided with a second engagement portion, the first engagement portion and the second engagement portion can be engaged to lock the exhaust trigger member,
• when the toggle member acts on the exhaust trigger member in the exhaust position, the exhaust trigger member moves downwardly to cause the second engagement portion to be engaged with the first engagement portion, and the exhaust trigger member maintains the exhaust apparatus in an opened state,
• when the self-locking member is triggered by the reset trigger member, the second engagement portion is disengaged from the first engagement portion, so that limiting is released between the self-locking member and the exhaust trigger member.

A cooking device, comprising:

• an exhaust assembly, comprising:
• an exhaust system, configured to be opened and closed;
• an exhaust trigger member, connected to the exhaust system and adapted to trigger the exhaust system to open;
• a reset trigger member, connected to the exhaust system and adapted to trigger the exhaust system to close;
• and
• a toggle member, adapted to move between an exhaust position and a closing position, wherein in the exhaust position, the toggle member acts on the exhaust trigger member and causes the exhaust trigger member to trigger the exhaust system to open, and in the closing position, the toggle member acts on the reset trigger member and causes the reset trigger member to trigger the exhaust system to close;
• wherein
• at least one of the reset trigger member and the exhaust trigger member comprises a push rod and a push rod elastic member, the push rod elastic member is connected to the push rod, and when the toggle member acts on the push rod, the push rod triggers the exhaust system and compresses the push rod elastic member, wherein elastic restoring of the push rod elastic member causes the push rod to stop triggering the exhaust system;
• and
• a pressing plate, for connecting with an upper cover, wherein the push rod is provided with a stopping edge, the push rod passes through the pressing plate, the stopping edge is spaced apart from the pressing plate, the push rod elastic member abuts against the pressing plate and the stopping edge, and the push rod is movable relative to the pressing plate to cause the stopping edge and the pressing plate to move close to each other to compress the push rod elastic member, or to cause the stopping edge and the pressing plate to move away from each other to release the push rod elastic member.
