Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application is a continuation of international patent application No. PCT/CN2025/078407, filed on Feb. 21, 2025, which claims priority to Chinese patent application No. 202411205301.8, filed on Aug. 30, 2024, and titled “COOKING APPARATUS”. The contents of the above identified applications are hereby incorporated herein in their entireties by reference. TECHNICAL FIELD The present disclosure relates to the field of kitchenware technology, and in particular, to a cooking apparatus. BACKGROUND Baking and cooking equipment such as ovens and steam ovens generates circulating hot air flows through a hot air unit to heat and cook food materials. The hot air flows first flow out of the hot air unit, then pass through a hot air baffle to enter a cooking cavity. Subsequently, the hot air flows turn around, flow back toward the hot air baffle and pass through the hot air baffle again. A circulation process is completed when the hot air flows return to the hot air unit, and the food is cooked after the above circulation process is repeated multiple times. It is generally desirable that the hot air flows remain in the baking and cooking equipment for as long as possible, so that the hot air flows can perform multiple rounds of circulation to fully utilize the heat carried by the hot air flows, and avoid the hot air unit from frequently heating the air to increase power consumption. However, the current difficulty lies in the inability to balance safety and multiple circulations of the hot air flows. Restricting the outward discharge of the hot air flows can increase the residence time and circulation times of the hot air flows in the baking and cooking equipment, but since a large amount of hot air flows cannot be discharged and accumulate in the cooking cavity, the air pressure in the cooking cavity increases sharply, and the user is highly likely to be scalded by the hot air flows when opening the cooking cavity to take food. SUMMARY In view of above, the present disclosure provides a cooking apparatus that allows hot air flows to be discharged outward while limiting an outward discharge rate of the hot air flows, in order to balance a safety during food taking and an increase of circulation times and residence time of the hot air flows in the cooking apparatus. The present disclosure provides a cooking apparatus. The cooking apparatus includes a heat-gathering unit and an external discharge unit. The heat-gathering unit includes an external discharge connecting member and is provided with a cooking cavity formed on an inner side of the external discharge connecting member. The external discharge unit includes a flow guide member and a baffle member. The flow guide member is connected to the external discharge connecting member and is provided with an external discharge channel. The external discharge connecting member and the flow guide member form an exhaust path. The baffle member is arranged on the exhaust path and is provided with an external leakage gap. The external leakage gap is in communication with the cooking cavity and the external discharge channel; and/or, the external leakage gap is in communication with the external discharge channel and an outside of the cooking apparatus. In some embodiments, the external discharge connecting member is provided with an air outlet hole in communication with the external discharge channel. The baffle member includes a ventilation cover covering the air outlet hole, the ventilation cover includes a baffle side wall protruding from the inner side of the external discharge connecting member. The external leakage gap includes a first leakage gap formed on the baffle side wall of the ventilation cover, and the first leakage gap is in communication with the cooking cavity and the air outlet hole. In some embodiments, the cooking apparatus further includes a hot air unit. A part of the baffle side wall adjacent to the hot air unit forms a rear part of the baffle side wall. A part of the baffle side wall away from the hot air unit forms a front part of the baffle side wall. The first leakage gap is entirely formed on the front part of the baffle side wall. Alternatively, the first leakage gap includes a rear leakage gap formed on the rear part of the baffle side wall and a front leakage gap formed on the front part of the baffle side wall, and an opening size of the front leakage gap is greater than that of the rear leakage gap. In some embodiments, the external discharge connecting member includes a front end and a rear end. The front end of the external discharge connecting member is arranged away from the hot air unit. The rear end of the external discharge connecting member is arranged adjacent to the hot air unit. A distance between the air outlet hole and the front end of the external discharge connecting member is greater than a distance between the air outlet hole and the rear end of the external discharge connecting membe
