The use of the pot cover is not enough in cooking operations such as cooking, stewing and frying, and the like. The pot cover mainly comprises a cover body and a handle of the pot cover. Because the cooking process is mostly high-temperature operation, the pot cover can be continuously raised by action temperature of hot steam, hot oil smoke and the like in the food covering process, and meanwhile, if the pot cover is too tight, danger can be caused. In order to effectively remove domestic hot steam in the cooking process, the cooker cover is often provided with air outlets and other characteristics. However, the air outlet is often fixedly arranged, so that the pressure relief and air exhaust effects are often more effective. Meanwhile, when the container is used, the personnel often cannot pay attention to the position of the air outlet, so that the container is inconvenient to operate. The market has few devices for pressure relief and air exhaust through a handle of a pot cover.

At present, the existing exhaust pressure relief valves on the market are not shielded, steam cannot be discharged directionally, and condensed water cannot flow back into a pot, so that a user is scalded. The ordinary anti-overflow pot cover is not provided with a closed silica gel valve, and the food is quickly oxidized due to the unobstructed circulation of air in the cooking process. After the pot cover is flatly placed, condensed water and cooking oil stain condensation directly flow out to pollute the environment of the table top. The common handle with the metal screw cover is complex in installation, needs professional tools, is difficult to clean the metal screw and the periphery of the part due to easy condensation and dirt, and is easy to corrode the metal part to influence sanitation.

The present invention will be described in further detail with reference to the accompanying drawings, but the present invention is not limited by the following detailed description.

Fig. 1 is a schematic front view of a handle according to a preferred embodiment of the present invention. Fig. 2 is a schematic bottom view of fig. 1. Fig. 3 is a schematic perspective view of fig. 1. As can be seen from fig. 1 to 3, the mounting handle in the preferred embodiment is composed of a handle mounting portion 1, a sealing exhaust valve 2, a connecting ring 3, a sealing ring 4 and a lower flange 5. The handle holding part 1 is an integrally formed structural member, the main body of the handle holding part is a holding rod 11 with a nearly rectangular flat plate structure, and the bottom of the holding rod 11 is connected with a cylindrical connecting column 12. The free end face of the connecting rod 11 is provided with an inwards concave curved surface, and two supporting points are arranged at two ends of the curved surface. The connecting column 12 is provided with a cavity with an opening at the bottom for accommodating and connecting the sealed exhaust valve 2 and the lower flange 5. The side of the connecting column 12 is provided with a strip-shaped vent hole 13, and the vent hole 13 and the holding rod 11 are positioned at two sides of the connecting column 12.

The outer diameter of the bottom of the connecting column 12 is provided with a ring groove for sleeving the connecting ring 3, and the periphery of the bottom of the lower flange 5 is provided with an outer convex ring. The connecting ring 3 is sleeved on the annular groove at the bottom of the connecting column 12, and the bottom surface of the connecting ring 3 and the upper surface of the convex ring of the lower flange 5 are in press connection with the sealing ring 4.

Fig. 4 is a schematic longitudinal sectional structure diagram of a handle according to a preferred embodiment of the present invention. As can be seen from fig. 4, in the preferred embodiment, the lower flange 5 is a hollow cylinder structure, and has an outwardly convex ring 51 on the outer side of the bottom and an inwardly convex ring 52 on the upper side. The outer wall of the upper part of the lower flange plate 5 is provided with an external thread, the upper part of the inner wall of the connecting column 12 is provided with an internal thread, and the lower flange plate 5 is connected inside the connecting column 12 through the thread. The top of the sealed exhaust valve 2 is provided with a tip-removed umbrella-shaped structure, and the bottom of the annular edge is superposed with the upper surface of the inner convex ring 52 of the lower flange 5. The bottom of the umbrella-shaped structure is connected with a plurality of cylindrical connecting rods, the tail ends of the connecting rods are connected into a whole through a circular ring structure, and the circular ring structure is arranged in a cavity of the lower flange 5. The outer diameter of the circular ring structure is larger than the inner diameter of the inner flange 52, thereby limiting the position of the sealing exhaust valve 2 which is jacked up by steam.

In use, steam from the boiler rises through the internal cavity of the lower flange 5 and into the cavity of the connecting column 12. As the steam pressure increases, the steam pushes up the sealing exhaust valve 2 to communicate with the exhaust hole 13, forming a steam passage for exhausting the gas outwards. When the steam pressure is insufficient. The sealing vent valve 2 will fall under gravity onto the inner collar 52 of the lower flange 5. When the pot cover needs to be taken up, the pot cover can be vertically arranged on a plane at 90 degrees, wherein the edge of the pot cover provides a supporting point, and two ends of the free surface of the holding rod 11 provide two supporting points to form a stable triangular support. In addition, the lower surface of the outer collar 51 of the lower flange 5 is a 15 degree inner slope surface, thereby facilitating the backflow of the condensed water. The handle can release the high-temperature steam in a specific direction only after the pressure in the cooker reaches a certain degree, and the high-temperature steam is sprayed in a direction opposite to the direction of the person. Therefore, high-temperature steam can be released, the pressure relief effect is achieved, and scalding of a user can be avoided.

Although the present invention has been described with reference to the preferred embodiments, it should be understood that various changes and modifications can be made by those skilled in the art without departing from the spirit and scope of the invention.
