[0033] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0034] Please refer to Figures 1 to 3 The utility model provides a protective stove, comprising a stove 1 and a self-locking mechanism 4. A self-locking cavity 3 is provided inside the stove 1. The self-locking mechanism 4 is installed in the self-locking cavity 3 and is connected to a knob 2 on the stove 1.

[0035] The self-locking mechanism 4 includes a connecting rod 41, a limiting gear 47, a limiting rack 46, a connecting block 42, a limiting block 43, a supporting rod 45 and a first spring 44;

[0036] The connecting rod 41 is fixedly connected to the bottom of the knob 2;

[0037] The connecting block 42 is fixed on the connecting rod 41;

[0038] The limiting gear 47 is installed at the bottom of the connecting block 42;

[0039] The limiting rack 46 is meshed with the limiting gear 47;

[0040] The support rod 45 is fixed to the back of the limiting rack 46, and a limiting groove corresponding to the support rod 45 is opened inside the self-locking cavity 3;

[0041] The first spring 44 is sleeved on the support rod 45, one end of the first spring 44 is connected to the limiting rack 46, and the other end of the first spring 44 is connected to the inner wall of the self-locking cavity 3;

[0042] The limiting block 43 is fixed above the limiting rack 46. When the connecting rod 41 drives the connecting block 42 to move downward, the connecting block 42 pushes the limiting block 43 away.

[0043] When in use, the knob 2 is manually pressed down, and the connecting block 42 is driven to move downward by the connecting rod 41. During the downward movement of the connecting block 42, the limit block 43 can be pushed to one side. At this time, the limit rack 46 no longer engages the limit gear 47, and the knob 2 can be directly rotated to start the gas stove or adjust the firepower of the gas stove. After releasing the knob 2, under the action of the second spring 48, the knob 2 moves upward and resets. At the same time, the limit gear 47 also moves upward, and the limit rack 46 is also reset under the action of the first spring 44, and re-engages with the limit rack 46, thereby limiting the rotation of the knob 2. In this application, the prerequisite for rotating the knob 2 is to press the knob 2, which not only prevents children from accidentally turning the knob 2, but also prevents the problem of accidentally turning the knob 2 during wiping the stove.

[0044] In this embodiment, a second spring 48 is sleeved on the connecting rod 41, one end of the second spring 48 is connected to the bottom of the limiting gear 47, and the other end of the second spring 48 is connected to the bottom of the self-locking cavity 3; the second spring 48 is set to reset the knob 2 after pressing the knob 2.

[0045] In this embodiment, the connecting block 42 is a conical structure that is larger at the top and smaller at the bottom, and is arranged coaxially with the connecting rod 41. The side of the limit block 43 close to the connecting block 42 is provided with an inclined surface that is adapted to the side wall of the connecting block 42. When the inclined surface of the outer wall of the connecting block 42 moves downward and contacts with the inclined surface adapted to the side wall of the connecting block 42, the connecting block 42 can be pushed to one side.

[0046] In this embodiment, the diameter of the limiting gear 47 is between the diameters of the bottom and top surfaces of the connecting block 42 , which can ensure that the connecting block 42 is not blocked by the limiting rack 46 engaged with the limiting gear 47 during its downward movement.

[0047] The working principle of this utility model is as follows:

[0048] Manually press the knob 2 down, and the connecting block 42 is driven to move downward by the connecting rod 41. During the downward movement of the connecting block 42, the limit block 43 can be pushed to one side. At this time, the limit rack 46 no longer engages the limit gear 47, and the knob 2 can be directly rotated to start the gas stove or adjust the firepower of the gas stove. After releasing the knob 2, under the action of the second spring 48, the knob 2 moves upward and resets. At the same time, the limit gear 47 also moves upward, and the limit rack 46 is also reset under the action of the first spring 44, and re-engages with the limit rack 46, thereby limiting the rotation of the knob 2. In this application, the prerequisite for rotating the knob 2 is that the knob 2 needs to be pressed, which not only prevents children from accidentally turning the knob 2, but also prevents the problem of accidentally turning the knob 2 during wiping the stove.
