In order to achieve the above purpose, the present utility model is achieved through the following technical solutions:

A scald-proof heating pot includes a pot body and a lid. The top of the pot body is provided with a supporting sleeve body. The diameter of the supporting sleeve body gradually increases from bottom to top, and the top end of the supporting sleeve body and The kettle body is fixedly connected, a gap is left between the outer wall of the support sleeve body and the inner wall of the kettle body, the support sleeve body is provided with an exhaust hole, and the bottom of the kettle lid is provided with a seal adapted to the support sleeve body Part, the diameter of the sealing part gradually increases from bottom to top, the diameter of the bottom end of the sealing part is smaller than the inner diameter of the top end of the support sleeve, and the diameter of the top end of the sealing part is larger than the inner diameter of the bottom end of the support sleeve;

And when the pot cover is buckled on the pot body, the bottom end of the sealing part is located at the lower side of the top end of the vent hole, and a gap is left between the outer wall of the sealing part and the inner wall of the supporting sleeve.

Preferably, the diameter of the top end of the sealing portion is larger than the inner diameter of the top end of the support sleeve.

Preferably, the outer shape of the sealing portion is hyperboloid.

Preferably, the number of the vent holes is at least two.

Preferably, the vent hole is located on one side of the kettle body.

Compared with the prior art, the beneficial effects of the present invention are as follows:

In the utility model, the vent hole is opened on the support sleeve body in the kettle body. After the water vapor in the kettle body is discharged from the vent hole, it collides with the outer surface of the sealing part and reflects out, thereby changing the direction of the water vapor discharge and reducing the original The discharge from directly above becomes obliquely upward, which can prevent the user from being scalded, and the steam can be condensed on the outer wall of the sealing part and can flow back into the kettle body through the exhaust hole, which can reduce the discharge of water vapor.

detailed description

In the following, the present utility model will be further explained in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present utility model and not to limit the scope of the present utility model. In addition, it should be understood that after reading the content taught by the present utility model, those skilled in the art can make various changes or modifications to the present utility model, and these equivalent forms also fall within the scope defined by this application.

Example: As shown in Figures 1-3, the utility model described is an anti-scald heating pot, including a body 1, a lid 2, and a supporting sleeve 3 on the top of the body 1, so The diameter of the supporting sleeve body 3 gradually increases from bottom to top, and the top end of the supporting sleeve body 3 is fixedly connected with the kettle body 1, and an integrated structure can be adopted between the supporting sleeve body 3 and the kettle body 1. There is a gap between the outer wall of the sleeve body 3 and the inner wall of the kettle body 1. The support sleeve body 3 can be a truncated cone-shaped sleeve body. The height of the support sleeve body 3 can be determined according to the size of the kettle body 1, generally no more than 2cm. . The supporting sleeve body 3 is provided with vent holes 4, the number of vent holes 4 is not limited, it can be one or more, preferably at least two, and the gap between two adjacent vent holes 4 The distance is not more than twice the inner diameter of the exhaust hole 4, and the exhaust can be quickly exhausted. Further, the exhaust hole 4 is located on one side of the kettle body 1. When in use, the user stands on the side away from the exhaust hole 4 and grasps the handle on the kettle body 1, which can make the exhaust position far away from the user. , To further eliminate the risk of scalding the user. The bottom of the pot cover 2 is provided with a sealing part 5 that is compatible with the supporting sleeve body 3. The sealing part 5 and the pot cover 2 can adopt an integrated structure, or a snap connection or other connection methods can be used to fix the sealing part 5 Fixed at the bottom of the protective cover 2, the diameter of the sealing portion 5 gradually increases from bottom to top, and the shape of the sealing portion 5 can be a large truncated cone on the bottom, and preferably, the shape of the sealing portion 5 is a hyperboloid The shape can increase the area of the outer surface of the sealing portion 5, provide a larger adhesion area for the condensation of water vapor, and improve the effect of water vapor condensation. The diameter of the bottom end of the sealing portion 5 is smaller than the inner diameter of the top end of the supporting sleeve body 3, and the diameter of the top end of the sealing portion 5 is larger than the inner diameter of the bottom end of the supporting sleeve body 3, so as to ensure that the sealing portion 5 can support the bottom of the sleeve body 3. The end is closed. Preferably, the diameter of the top end of the sealing portion 5 is larger than the inner diameter of the top end of the support sleeve body 3, which can completely cover the top end of the support sleeve body 3, and keep the water vapor removal position as far away as possible from the user;
