Description

Door opening structure and cooking equipment Technical Field The utility model relates to the technical field of household appliances, in particular to a door opening structure and cooking equipment. Background With the continuous promotion of people's pursuit of food, cooking equipment has become important household electrical appliances that promote quality of life, demonstrate individual taste and pursuit healthy life. The existing cooking equipment comprises a box body and a door assembly hinged with the box body, wherein the other side of the door assembly is matched with a limiting part of the box body through a door hook so as to limit the door assembly to be opened or closed relative to the box body. In addition, if the door component is opened by children at will, the risk of scalding food heated in the box body exists. The Chinese patent with the application number 202321016091.9 discloses a door lock structure and cooking equipment, wherein the door lock structure comprises a door hook arranged on a door assembly, a switch bracket arranged inside a box body and clamped and matched with the door hook, a door opening assembly arranged on a control panel box and comprising a door opening key and a rotating plate, the door opening key can drive the rotating plate to rotate upwards to push the door hook to be separated from the switch bracket, and an electromagnetic switch arranged on the switch bracket and provided with a telescopic rod, wherein the telescopic rod can enter a rotating path of the rotating plate under an extending state so as to stop the rotating plate from rotating upwards and correspondingly keep the door hook in a clamped state. However, the electromagnetic switch in this solution requires an additional connection line and can cause the door assembly to fail to open in the power-off state, resulting in poor user experience. In view of this, the present utility model has been made. Disclosure of utility model The utility model solves the problem that the related structure of the existing cooking equipment with the secondary door opening function is complex, and the door assembly can not be opened in the power-off state by arranging the electromagnetic switch, so that the user experience is poor. The utility model provides a door opening structure which comprises a door hook arranged on a door body, a switch bracket arranged in a box body and clamped and matched with the door hook, and a door opening assembly arranged on a control panel box, wherein the door opening assembly comprises a door opening key, the door opening key can be pressed to release the constraint state of the door hook so as to open the door body, and the door opening assembly further comprises a first stop block which is assembled on the control panel box in a limiting mode and can slide along the outer side wall of the door opening key so as to release the constraint of the door opening key, so that the door opening key can be pressed and act. The application can be opened after two steps of different simple operations by a user, effectively prevents children from opening the door by mistake, improves the safety and reliability of the cooking equipment, prevents the opening and closing of the door body from being influenced by whether the power is on or not, can take out heated food even in a temporary power-off state, and has good user experience. When the first stop block is positioned at the first position, the door opening button can be limited to act, and the door is prevented from being opened accidentally due to false touch or other unexpected operations. Preferably, the door opening assembly further comprises a second reset piece, the door opening key is provided with an assembly hole at one side close to the first stop block, the second reset piece is located in the assembly hole, and when the first stop block is located at the second position, the second reset piece deforms to generate restoring force. The arrangement can enable the second reset piece to continuously apply restoring force, ensure that the first stop block can automatically return to the first position after the unlocking action is finished, avoid the first stop block to be retained at the second position due to misoperation or mechanical clamping stagnation of a user, and further maintain the reliability of the locking function of the door body. Preferably, a lock pin is arranged at the side part of the first stop block, the extending direction of the lock pin is perpendicular to the moving direction of the door opening key, a limit groove is arranged at the position of the control panel box corresponding to the lock pin, and when the first stop block is positioned at the first position, the lock pin is inserted into the limit groove. The device realizes rigid constraint by forming a similar mortise-tenon structure through the vertical plug-in relation of the lock pin and the limit groove, has high reliability, and can effectively limit
