Description

Technical Field

[0001] The utility model relates to the technical field of pressure cookers, in particular to a pot cover assembly and an electric pressure cooker. Background Art

[0002] Taking the current electric pressure cooker as an example, it includes a pot body and a pot cover. The top of the pot body is annularly arranged with concave and convex pot teeth, and the inner wall of the pot cover is provided with buckling teeth corresponding to the pot teeth. The pot cover is rotated so that the buckling teeth are under the convex pot teeth to achieve buckling connection between the pot cover and the pot body. Conversely, when the buckling teeth rotate with the pot cover to under the concave pot teeth, the pot cover can be flipped up or opened. Since it is dangerous to open the lid when the air pressure in the pot is high, existing pressure cookers are all equipped with a self-locking mechanism, which includes an air float valve that floats up and down as the air pressure in the pot changes, and a lock pin assembly that is laterally slidably arranged in the pot lid, one end of the lock pin assembly is attached to the surface of the pot teeth of the pot body, and the other end of the lock pin assembly extends to the air float valve. Under normal circumstances, if the air pressure in the pot is lower than the safe lid opening pressure, the air float valve will not block the lock pin assembly. When the pot lid is rotated to open, the lock pin assembly moves freely along the pot teeth surface and does not affect the lid opening; on the contrary, when the air pressure in the pot is too high, the air float valve blocks the lock pin assembly so that the lock pin assembly cannot move freely along the pot teeth surface of the pot body, so the pot lid cannot rotate. Of course, the above is only a theoretical state, but this structure actually still has certain safety hazards, because there must be a certain virtual position between the air float valve and the lock pin assembly (if there is no virtual position, the air float valve will be stuck). Even if the air pressure in the pot is high, if the rotational force acting on the pot lid to open the lid is large, the lock pin assembly can overcome the resistance of the air float valve and change the state of the air float valve. The lid can be opened in this state that is not conducive to opening the lid, which brings huge safety hazards. Therefore, it is necessary to improve this structure. Utility Model Content

Along the rotation direction of the adjusting member 320, one side of the limiting protrusion 120 can abut against one side of the limiting groove 3202, and the other opposite side of the limiting protrusion 120 can abut against the other opposite side of the limiting groove 3202, thereby limiting the rotation angle of the adjusting member 320.

[0040] It should be noted that the limiting structure can also be a structure in which a waist-shaped hole and a limiting pin are coordinated. The limiting pin is arranged on the wall surface of the accommodating cavity 110, and the waist-shaped hole is arranged on the adjusting member 320 and has an arc-shaped structure. The limiting pin passes through the waist-shaped hole and can abut against the side wall of the waist-shaped hole, and can also limit the rotation angle of the adjusting member 320, which is not limited here.

[0046] Reference Figure 5 , Figure 6 In some embodiments of the present invention, the adjustment component further includes an elastic member 330, and the elastic member 330 is used to make the other end of the transmission member 310 abut against the abutment portion 3201, so that the adjustment member 320 can stably drive the transmission member 310 to rotate.

[0047] Specifically, the elastic member 330 is a component such as a compression spring that can undergo axial elastic deformation. The elastic member 330 is arranged between the transmission member 310 and the pot cover body 100. One end of the elastic member 330 abuts against the pot cover body 100, and the other end of the elastic member 330 abuts against the transmission member 310. When the transmission member 310 pushes the locking member 200 to move in a direction away from the middle position of the pot cover body 100, the elastic member 330 is compressed, so that the elastic member 330 can push the other end of the transmission member 310 to abut against the abutment portion 3201, thereby ensuring that the adjustment member 320 can stably drive the transmission member 310 to rotate.

[0048] It should be pointed out that the elastic member 330 can also be a torsion spring, which is sleeved on the hinged end of the transmission member 310. One end of the torsion spring is connected to the transmission member 310, and the other end is connected to the pot cover body 100. It can also make the other end of the transmission member 310 abut against the abutment part 3201, which is not described in detail here.

[0051] Specifically, the first guide bar 130 and the second guide bar 140 are arranged relatively to form a guide groove, and one end of the locking member 200 away from the locking portion 210 is accommodated in the guide groove, which can guide the locking member 200 so that the locking member 200 can move along a preset direction.

[0052] It should be noted that the guide structure can also be a structure in which a guide hole and a guide protrusion cooperate with each other. The guide protrusion is arranged on the wall surface of the accommodating cavity 110, the guide hole is a long strip structure, and the guide hole is arranged on the locking member 200. The guide protrusion is passed through the guide hole and can abut against the side wall of the guide hole, and can also guide the locking member 200, which will not be described in detail here.

[0053] Reference Figure 5 , Figure 6 In some embodiments of the present invention, the adjustment component also includes a reset member 340, which is arranged between the locking member 200 and the pot cover body 100. The reset member 340 is used to switch the locking member 200 from the second state to the first state, so that the locking member 200 can be automatically reset to lock the pot cover body 100, which can improve the reliability of the electric pressure cooker.

[0054] Specifically, the reset member 340 is a component such as a compression spring or rubber that can undergo axial elastic deformation. One end of the reset member 340 abuts against the side of the locking member 200 away from the locking portion 210, and the other end of the reset member 340 abuts against the pot cover body 100. When the adjusting member 320 drives the locking member 200 to move in a direction away from the middle position of the pot cover body 100, the reset member 340 is compressed. When the user releases the adjusting member 320, the reset member 340 can drive the locking member 200 to automatically reset to lock the pot cover body 100, thereby improving the reliability of the electric pressure cooker.
