A rotation column 310 is provided at the bottom of the handle 300 through the first opening hole 211, and the radius of the first opening hole 211 may be slightly larger than that of the rotation column 310, so that the rotation column 310 may rotate in the first opening hole 211. Thus, when the handle 300 is rotated with respect to the opening part 400, the rotating post 310 is also rotated in the first opening 211.

The opening and closing member 400 includes an opening and closing portion 420 and a rotating portion 410 connected to each other, the rotating portion 410 may be located at a side of the opening and closing portion 420, the opening and closing portion 420 may be located at an outer side of the second fixing portion 220, and a bottom of the opening and closing portion 420 is closely attached to a top surface of the cover body 100, so that the opening and closing portion 420 may cover the ventilation holes 110 or be removed from the ventilation holes 110 to open the ventilation holes 110. The rotating portion 410 is disposed in the receiving groove 230 and can rotate in the receiving groove 230, and meanwhile, the rotating portion 410 is fixed on the rotating column 310, so that the rotating portion 410 is linked with the handle 300, and when the handle 300 rotates, the rotating portion 410 rotates correspondingly.

Having an open position and a closed position in the rotational path of the handle 300. When the handle 300 rotates to the closed position, the opening and closing part 420 covers the air holes 110, and the air in the pot body cannot be discharged from the air holes 110, so that the pot body keeps air tightness; when the handle 300 is rotated to the open position, the opening and closing part 420 is moved away from the ventilation holes 110 to open the ventilation holes 110, and the gas in the pot can be discharged from the ventilation holes 110. Therefore, when the pot cover of the embodiment is used, the opening and closing of the air holes 110 can be realized by rotating the handle 300 on the pot cover, and a user does not need to lift the pot cover, so that the pot cover is convenient for the user to use.

Meanwhile, the base 200, the handle 300 and the opening and closing member 400 of the present embodiment are all disposed on the top of the cover 100, so as to facilitate the overall assembly. The inner wall of the receiving groove 230 limits the rotating part 410, and prevents the opening and closing part 420 from moving upward along the axial direction of the rotating post 310, so that the bottom of the opening and closing part 420 is kept in a state of being closely attached to the top surface of the cover body 100.

In some embodiments, the top of the first fixing portion 210 is provided with a positioning hole 212, the positioning hole 212 may extend in a direction parallel to the axial direction of the rotation column 310, a spring 214 and a ball 213 are disposed in the positioning hole 212, a bottom end of the spring 214 is disposed at a bottom of the positioning hole 212, a top end of the spring 214 contacts the ball 213, and the spring 214 is in a compressed state in the positioning hole 212, which applies a thrust force to the ball 213, so that the ball 213 abuts against the bottom of the handle 300 under an elastic force of the spring 214. When the handle 300 rotates relative to the base 200, the balls 213 roll on the bottom surface of the handle 300, which changes the sliding friction into the rolling friction, so as to reduce the friction of the rotation of the handle 300 and facilitate the rotation of the handle 300.

In some embodiments, when the handle 300 is rotated relative to the base 200, the contact position of the balls 213 with the bottom of the handle 300 forms a continuous rolling path on the bottom surface of the handle 300, on which the catching hole 320 is provided. The balls 213 may be partially inserted into the card holes 320 while rolling on a rolling path. This embodiment provides that the handle 300 is in the open position when a portion of the balls 213 are inserted into the card holes 320. On one hand, after a portion of the balls 213 is inserted into the engaging holes 320, the resistance to the rotation of the handle 300 is increased, so that the handle 300 is not easily rotated, and thus the airing holes 110 can be maintained in the opened state. On the other hand, after a part of the ball 213 is inserted into the card hole 320, the user needs a larger force to disengage the ball 213 from the card hole 320, and the user can determine whether the ball 213 is inserted into the card hole 320, and accordingly determine whether the handle 300 is in the open position, which is more convenient for the user to use.

In some embodiments, the top of the first fixing portion 210 is provided with a protrusion 215, the bottom of the handle 300 is provided with an arc-shaped groove 330, the center of the arc-shaped groove 330 is located on the axis of the rotating column 310, and when the handle 300 rotates around the axis of the rotating column 310, the arc-shaped groove 330 rotates around the center of the arc-shaped groove. The protrusion 215 is disposed in the arc-shaped groove 330, and in the process that the handle 300 rotates relative to the base 200, the protrusion 215 moves in the arc-shaped groove 330, so as to guide and limit the rotation of the handle 300, so that the handle 300 keeps rotating around the axis of the rotating column 310, and the influence of the rotation deviation on the opening and closing of the air vent 110 is avoided.

To further enhance the guiding and limiting function, the protrusion 215 may be arc-shaped, and the center of the arc-shaped protrusion is located on the axis of the rotating column 310.

In some embodiments, since the length of the arc-shaped slot 330 is limited, when the handle 300 is rotated in a certain direction, the protrusion 215 moves towards one end of the extension direction of the arc-shaped slot 330, and when the protrusion 215 abuts against the inner wall of the end of the arc-shaped slot 330, the protrusion 215 cannot rotate continuously in the original rotation direction. This embodiment provides that the handle 300 is in the closed position when the projection 215 abuts against either of the inner walls at the two ends of the arcuate slot 330. When the user cannot rotate the handle 300 any more, indicating that the protrusion 215 abuts against the inner wall of the end of the arc-shaped slot 330, the user can determine whether the handle 300 is in the closed position, which is more convenient for the user. Meanwhile, when the handle 300 is not located at the closing position in the embodiment, the protrusion 215 abuts against the inner wall of the arc-shaped groove 330 at one end to limit, and the user rotates the handle 300 counterclockwise or clockwise to enable the handle 300 to rotate to the closing position, so that the user can use the handle conveniently.

On the basis of the above embodiments, this embodiment may further define that, when the handle 300 is in the open position, the protrusion 215 is located at the middle position of the extending direction of the arc-shaped groove 330, which makes the rotation angle of the handle 300 from the open position to the closed position in the counterclockwise direction be the same as the rotation angle of the handle 300 from the open position to the closed position in the clockwise direction, so that the user experiences the same rotation experience when rotating the handle 300 in any direction, and the use is more convenient.

In some embodiments, the bottom of the opening and closing part 420 is provided with an opening and closing plate 421, the opening and closing plate 421 can be tightly attached to the bottom of the cover body 100, the outer side surface of the opening and closing plate 421 is provided with a plurality of stoppers 422, and a slot 423 is formed between two adjacent stoppers 422. When the handle 300 is rotated to the closed position, the stopper 422 covers the ventilation hole 110, and when the handle 300 is rotated to the open position, the stopper 422 is removed from the ventilation hole 110, the slot 423 is located above the ventilation hole 110, and the gas flows through the ventilation hole 110 and is discharged from the slot 423.

In some embodiments, a threaded hole is formed on the bottom end surface of the rotating column 310, the rotating portion 410 is provided with a through hole 411, a first screw 510 penetrates through the through hole 411, and the first screw 510 is fixed in the threaded hole, so that the rotating portion 410 is fixed on the rotating column 310 through the first screw 510. Meanwhile, for the handle 300, the rotation part 410 functions like a spacer, and prevents the rotation column 310 from being released from the first opening hole 211.

In some embodiments, the second fixing portion 220 is provided with a second opening 221 therethrough, and the first opening 211 and the second opening 221 are coaxially disposed. When the first screw 510 is installed, the space of the receiving groove 230 is limited, which is inconvenient for operation, in this embodiment, the second fixing portion 220 is provided with the second opening 221, and the first screw 510 can pass through the second opening 221 and then be fixed in the threaded hole on the bottom end surface of the rotating column 310, so as to facilitate installation by a user.
