1 to 6 , a pot cover comprises a top cover 1 and an opening and closing mechanism, wherein the opening and closing mechanism is arranged on the top cover 1 , and the opening and closing mechanism comprises an opening and closing frame assembly 2 , a knob switch device 3 and a locking device 4 ;

The knob switch device 3 can drive the opening and closing frame assembly 2 to be in an open state or a locked state;

The knob switch device 3 has two limiting parts. When the opening and closing frame assembly 2 is in the open state, the locking device 4 is limitedly matched with the above-mentioned one limiting part. When the opening and closing frame assembly 2 is in the locked state, the locking device 4 is limitedly matched with the above-mentioned other limiting part.

The knob switch device 3 in the opening and closing mechanism of the pot cover of this embodiment has two limit parts, and the locking device 4 cooperates with the limit parts at different positions to adjust the opening and closing frame assembly 2 to an open state or a locked state. Compared with the prior art that the pot cover and the pot body 6 can only be fixedly connected to each other through multiple rotations relative to each other, this embodiment only needs to change the relative position of the knob switch device 3 and the locking device 4 once to achieve the opening of the pot cover and the pot body 6 separated from each other or the locking of the pot cover and the pot body 6 connected to each other. The operation is convenient and quick, which is convenient for users' daily use, and the structural design is reasonable and easy to manufacture.

In this embodiment, the specific structure of the opening and closing frame assembly 2 is as follows:

The first opening and closing frame 201 and the second opening and closing frame 202 are slidably matched with the top cover 1. When the first opening and closing frame 201 and the second opening and closing frame 202 are far away from each other, the opening and closing frame assembly 2 is in an open state. When the first opening and closing frame 201 and the second opening and closing frame 202 are close to each other, the opening and closing frame assembly 2 is in a locked state.

Meanwhile, a turntable 203 is provided on the top cover 1 to rotatably cooperate therewith, and a first connecting column 204 and a second connecting column 205 are symmetrically provided on the upper end surface of the turntable 203 . The first connecting column 204 is connected to the first opening and closing frame 201 , and the second connecting column 205 is connected to the second opening and closing frame 202 .

According to the above structure, the state realization principle of the opening and closing frame assembly 2 of this embodiment is as follows:

The knob switch device 3 acts on the first opening and closing frame 201 to slide relative to the top cover 1, and the first opening and closing frame 201 moves toward the edge of the top cover 1. Because the structure of the turntable 203 is provided, the first connecting column 204 and the second connecting column 205 on the turntable 203 are symmetrically arranged at the center of the turntable 203 and are on the same diameter line, so the turntable 203 plays a linkage role, and the first opening and closing frame 201 drives the turntable 203 to rotate through the first connecting column 204, and the second connecting column 205 on the turntable 203 drives the second opening and closing frame 202 to move toward the edge of the top cover 1. At this time, the first opening and closing frame 201 and the second opening and closing frame 202 are in a state of being separated, and the opening and closing frame assembly 2 is in an open state. Conversely, the reverse operation can realize that the opening and closing frame assembly 2 is in a locked state, which will not be repeated here.

Therefore, the first opening and closing frame 201 and the second opening and closing frame 202 can be linked to each other through the structure of the rotating disk 203 and the first connecting column 204 and the second connecting column 205. The entire linkage structure is reasonably arranged, and is convenient for assembly and maintenance.

In this embodiment, the specific configuration structure of the knob switch device 3 and the top cover 1 is as follows:

The top cover 1 further includes a handle 5 , the knob switch device 3 is rotatably matched with the handle 5 , the locking device 4 is disposed on the handle 5 , and one end of the knob switch device 3 is connected to the first opening and closing frame 201 .

The knob switch device 3 of this embodiment includes a knob member, a knob cover 301 and a knob connecting shaft 302. The knob cover 301 is connected to the handle 5 and forms a through slot for the knob member to cooperate with and pass through. The lower end of the knob member is linked to the first opening and closing frame 201 through the knob connecting shaft 302.

The locking device 4 of this embodiment includes a spring member 401 and a positioning bead 402 . The handle 5 is provided with a groove 501 for accommodating the spring member 401 . The limiting portion is a positioning groove 307 that can cooperate with the positioning bead 402 .

In the above structure, when the knob is rotated, the knob connecting shaft 302 can drive the first opening and closing frame 201 to move relative to the top cover 1, and the through groove formed by the knob cover 301 and the handle 5 can ensure the stability of the knob during rotation.

In this embodiment, the knob component includes a knob connecting portion 303 and a knob rotating portion 304. The knob connecting portion 303 is connected to the knob connecting shaft 302, and the knob rotating portion 304 cooperates with the through groove. The knob rotating portion 304 is an arc-shaped structure. A plurality of anti-slip protrusions 305 are provided on the side of the knob rotating portion 304, and an indicating arrow 306 is provided on the upper end surface of the knob rotating portion 304 and at the corresponding position of the limit portion.

The positioning groove 307 of this embodiment is arranged on the bottom end surface of the knob rotating part 304. When the positioning bead 402 contacts the bottom end surface of the knob rotating part 304, the spring part 401 is in a compressed state. When the positioning bead 402 cooperates with the positioning groove 307, the compression state of the spring part 401 is released. At the same time, because the positioning bead 402 is a spherical structure and the positioning groove 307 is a semicircular groove, it can be ensured that the positioning bead 402 can smoothly enter or roll out of the positioning groove 307, and the contact area between the positioning bead 402 and the bottom end surface of the knob rotating part 304 is small, and the friction force is small, which facilitates the relative movement operation of the knob rotating part 304 and the positioning bead 402.

The anti-slip protrusion 305 on the side of the knob rotating part 304 can increase the friction with the user's operating fingertips, making it easier for the user to rotate the knob. At the same time, together with the indicator arrow 306, it helps the user to more intuitively determine whether the opening and closing frame assembly 2 is in the open state or the locked state.

At the same time, in order to ensure the stability of the relative movement process between the first opening and closing frame 201 , the second opening and closing frame 202 and the top cover 1 , a guide groove 101 for the first opening and closing frame 201 and the second opening and closing frame 202 to slide and cooperate is provided on the top cover 1 .

Specifically, a clamping portion 206 is provided at the bottom of the first opening and closing frame 201 and the second opening and closing frame 202 , and the clamping portion can be fixedly matched with the pot body 6 more conveniently.

This embodiment further provides a pressure cooker, as shown in FIG. 2 and FIG. 6 , comprising a cooker body 6 and a cooker cover disposed on the cooker body 6 , wherein the cooker cover is the cooker cover described above.

In summary, the present embodiment has a reasonable structure, is easy and quick to operate, is convenient for users' daily use, and is easy to manufacture.

The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Therefore, any modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention are still within the scope of the technical solution of the present invention.
