[0030] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0031] Please refer to Figures 1 to 4 , a locking mechanism of a sterilizing pot, comprising:

[0032] Sterilizer body 1;

[0033] Connecting ears 2, a plurality of connecting ears 2 are connected to the outer side wall of the upper part of the sterilizing pot body 1, and a pivot shaft 3 is provided on the connecting ear 2, and the axis of the pivot shaft 3 is parallel to the tangent line of the outer wall of the sterilizing pot body 1;

[0034] A screw rod 4, wherein the screw rod 4 is pivotally connected to the connecting ear 2 via a pivot shaft 3, and the axial direction of the screw rod 4 is a vertical direction;

[0035] The screw rod 4 is rotated by the pivot shaft 3 to switch between the first state and the second state;

[0036] A first gear 5, the first gear 5 is coaxially threadedly connected with the screw 4;

[0037] The sterilizing pot cover 6 has buckles 61 on the outside thereof, the number of the buckles 61 is the same as the number of the connecting ears 2, and a circular track 62 is provided on the sterilizing pot cover 6;

[0038] A slider 7, wherein the slider 7 is slidably connected to the annular track 62;

[0039] A ring gear 8, the ring gear 8 is connected to the slider 7, and the thickness of the ring gear 8 is 2-3 times that of the first gear 5;

[0040] A handle 9 connected to the ring gear 8;

[0041] In the first state, due to the effect of gravity, the screw 4 of the sterilizing pot body 1 causes the first gear 5 on the screw 4 to be located below the connecting ear 2;

[0042] In the second state, the buckle 61 of the sterilizing pot cover 6 is located directly above the connecting ear 2 of the sterilizing pot body 1 , and the screw rod 4 is engaged with the buckle 61 , so that the first gear 5 is meshed with the ring gear 8 .

[0043] In the above implementation mode, in the first state, the sterilization pot cover 6 is connected to the sterilization pot body so that the buckle 61 of the body of the sterilization pot cover 6 is located above the connecting ear 2 of the sterilization pot body 1, and the screw 4 is rotated to the second state through the pivot shaft 3, and then the handle 9 is held and rotated clockwise to make the slider 7 slide on the annular track 62, thereby driving the annular gear 8 to rotate. Since the upper part of the annular gear 8 is engaged with the first gear 5, the first gear 5 is driven to rotate. The first gear 5 rotates to move the first gear 5 down along the screw 4 until the first gear 5 abuts against the upper part of the buckle 61. Compared with the prior art, not only is the operation simple, but the locking time of the sterilization pot cover 6 and the sterilization pot body 1 is also short.

[0044] As an optional implementation, a groove 11 is provided at the upper end of the sterilizing pot body 1 , and a sealing ring 12 is provided in the groove 11 .

[0045] In the above embodiments, the sterilization pot cover 6 and the sterilization pot body 1 can be better sealed to achieve a better sterilization effect.

[0046] As an optional implementation, a protective shell 10 is provided on the outer side of the ring gear 8 , and the protective shell 10 is provided with an opening 101 above the buckle 61 .

[0047] In the above embodiment, in the second state, the handle is rotated clockwise to make the slider 7 slide on the annular track 62, thereby driving the annular gear 8 to rotate. The annular gear 8 engages with the first gear 5 through the opening 101 of the protective shell 10, thereby driving the first gear 5 to move downward along the screw 4 until the first gear 5 abuts against the upper part of the buckle 61. By providing the protective shell 10, the annular gear 8 can be protected and the service life of the annular gear 8 can be extended.

[0048] As an optional implementation, the buckle 61 is U-shaped.

[0049] In the above embodiment, a U-shaped buckle 61 is provided. The U-shaped buckle 61 is made of plastic or elastic material. The structure of the U-shaped buckle 61 is utilized to better limit the screw 4 with the buckle 61 , so that the first gear 5 on the screw 4 can better mesh with the ring gear 8 .

[0050] As an optional embodiment, the screw rod 4 is detachably connected to the connecting ear 2 .

[0051] In the above embodiment, the connecting ear 2 is U-shaped, and a first through hole and a second through hole are provided on the connecting ear 2. The axis of the first through hole is the same as the axial direction of the second through hole, and the axis of the first through hole is parallel to the tangent line of the outer wall of the sterilizing pot body 1. A circular through hole is provided at the lower end of the screw 4. The bolt passes through the first through hole, the circular through hole, and the second through hole in sequence, and the screw 4 is fastened to the bolt so that the screw 4 can rotate along the bolt, thereby realizing the detachable connection of the screw 4 to the connecting ear 2, and the broken screw 4 can be replaced and repaired at any time.

[0052] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent transformations made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in the relevant technical field, are also included in the patent protection scope of the present invention.
