The novel safety door opening button mechanism as shown in the attached figures 2-4 comprises a door pushing button 1, a locking bracket 2, a locking key 3 and an electric appliance control box 4; the door pushing button 1, the locking bracket 2 and the locking key 3 are movably arranged on the electric appliance control box 4; the locking key 3 comprises a return spring 5, the locking bracket 2 is provided with a locking position and an unlocking position, and the locking bracket 2 performs position switching between the locking position and the unlocking position through the locking key 3; when the locking bracket 2 is positioned at the locking position, the locking bracket 2 forms key operation limitation on the push door button 1; when the locking bracket 2 is positioned at the unlocking position, the key operation restriction of the push button 1 by the locking bracket 2 is released. The novel safe door opening button mechanism of this embodiment is a structure for locking the door pushing button 1, so that the door pushing button 1 can be normally operated by a front unlocking operation before key operation, and the locking function of the door pushing button 1 is realized through a simple mechanical structure, so that the novel safe door opening button mechanism is mainly applicable to electric products such as cooking appliances, etc. which need to ensure safe operation and safe operation, so as to improve the safety of the corresponding electric door body structure, and avoid the condition of scalding danger caused by the improper use and operation of the door body. In the initial state, the locking bracket 2 is positioned at the locking position and locks the door pushing button 1, so that the door pushing button cannot be operated by a key, namely the door cannot be opened; when the door opening operation is needed, the locking key 3 is operated firstly, so that the locking bracket 2 is switched to the unlocking position, and the key operation restriction on the door pushing button 1 is released, at the moment, the normal key operation can be carried out on the door pushing button 1, and the door opening and closing can be normally operated; when the locking button 3 is released, the locking button 3 and the locking bracket 2 can be reset to the initial positions under the action of the reset spring 5, and the novel safety door opening button mechanism is revalidated and resumes the locking protection of the push door button 1.

It should be noted that the utility model aims to provide a novel safe door opening button mechanism with a pure mechanical structure, which does not need electronic devices, has fewer parts, small change to the existing electrical structure, small destructive influence to the appearance of the cooking electrical product, and is also beneficial to reducing the production and installation costs, and simultaneously, the operation of users is simple and convenient. As shown in the drawings, in this embodiment, the door pushing button 1 is slidably disposed along a first direction, and a travel guide post 6 is disposed along the first direction; the gear avoiding holes 7 are correspondingly formed in the locking support 2, the stroke guide posts 6 are opposite to the gear avoiding holes 7 in a dislocation mode when the locking support 2 is located at the locking position, and the stroke guide posts 6 are opposite to the gear avoiding holes 7 when the locking support 2 is located at the unlocking position. The first direction in this embodiment specifically refers to the key operation direction of the push button 1 (the x-axis direction in the drawing may be understood as the front-rear direction of the electrical control box 4 in the embodiment), specifically, in this embodiment, the locking bracket 2 is disposed behind the push button 1, before the lock key 3 is not operated, since the stroke guide post 6 is opposite to the gear avoiding hole 7, that is, at this time, the stroke guide post 6 is blocked by the locking bracket 2, so that the push button 1 cannot be pressed backward, that is, cannot perform key operation, and thus, a key locking effect is achieved. Only after carrying out the unblock operation of locking button 3, make stroke guide post 6 with gear dodges hole 7 is just opposite, dodges stroke guide post 6 through gear dodges hole 7 this moment to remove the restriction that blocks to pushing away door button 1, make it can carry out normal button operation, realize button unblock effect.

In the above embodiment, in order to improve the smoothness of the movement of the door pushing button 1, a sliding guide post 8 is disposed in the same direction as the travel guide post 6, and as shown in the drawings, the sliding guide post 8 is disposed in the middle of the door pushing button 1, and is slidably sleeved on the electrical appliance control box 4 through the sliding guide post 8 during installation, so as to improve the key operation effect of the door pushing button 1 under the sliding guide effect. In this embodiment, the number of the travel guide posts 6 is two, and the travel guide posts are specifically disposed on two sides of the sliding guide post 8. It is to be understood that the number and positions of the sliding guide posts 8 and the travel guide posts 6 in the present embodiment are set based on the shape and size of the push button 1 in the present embodiment, that is, the present utility model is not limited to the embodiment shown in the drawings, and may be flexibly set and changed according to specific situations in practical application.

As a possible implementation manner, in this embodiment, the locking bracket 2 is slidably disposed along a second direction, where the second direction is perpendicular to the first direction. The second direction in this embodiment specifically refers to a side direction of the push button 1, that is, a direction perpendicular to a key operation direction of the push button 1 (a y-axis direction in the drawing may be understood as a left-right direction of the electrical control box 4 in the embodiment). In the initial state, the gear avoiding hole 7 on the locking bracket 2 is not aligned with the travel guide post 6 in front of the gear avoiding hole, so that the key operation of the push door button 1 is blocked; when the locking key 3 is pressed, the locking bracket 2 is pushed to move to the right side in the drawing, so that the gear avoiding hole 7 is aligned to the travel guide post 6 in front of the gear avoiding hole, and the door button 1 can be pushed back by the travel guide post 6 in front of the gear avoiding hole to move in the front-back direction of the electrical control box 4 without resistance, namely, key operation can be normally performed; when the locking button 3 is released, the locking button 3 and the locking bracket 2 can move to the left side of the diagram to return to the initial position under the action of the return spring 5, and the novel safety door opening button mechanism is in effect again, so that the locking protection of the push door button 1 is restored. It should be noted that, the drawings are only a preferred embodiment of the present utility model, and not the only limitation of the arrangement of the locking bracket 2, but also other possible relative movement modes may be adopted, for example, sliding arrangement or rotation arrangement along other directions, so long as the position switching between the locking position and the unlocking position by the locking key 3 can be realized, so as to lock or unlock the push door button 1.

Referring to the drawings, in the present embodiment, the locking bracket 2 is provided with a mounting hole 9, and the locking bracket 2 is slidably mounted on the appliance control box 4 by a fastener. Specifically, the fastener passes through the mounting hole 9 and then installs the locking bracket 2 on the electrical appliance control box 4, so that the locking bracket 2 can slide along the second direction to switch the locking position and the unlocking position after being installed, the mounting hole 9 of the embodiment is a long hole arranged along the second direction, and after the fastener passes through the long hole, due to the clearance left in the second direction, the locking bracket 2 can still move along the second direction to realize locking or unlocking limitation of the push door button 1. The fastening piece may be a screw 10 shown in the attached drawings, a mounting screw hole 11 is correspondingly formed in the electrical control box 4, the screw 10 penetrates through the long hole and then is screwed into the mounting screw hole 11, and the locking bracket 2 is mounted on the electrical control box 4. In some embodiments, the screw 10 may be replaced by a fastening structure provided on the appliance control box 4, so long as the locking bracket 2 can be slidably mounted on the appliance control box 4.
