Referring to fig. 1 and 2, a floating structure of a pressure cooker includes a cooker cover 10, a hinge base 20 and a floating assembly 30. Wherein, the pot cover 10 is provided with a first mounting hole 101; one end of the hinge base 20 is rotatably connected with the cooker cover 10, the other end of the hinge base is used for being hinged with the cooker body 40 of the pressure cooker, the hinge base 20 is provided with a second mounting hole 201, the second mounting hole 201 is provided with an upper port penetrating through the top surface of the hinge base 20, a limiting rib 221 is arranged in the upper port, and an observation port 202 is formed in the area, which is not covered by the limiting rib 221, of the upper port; the float assembly 30 comprises a first float rod 31 and a second float rod 32, the first mounting hole 101 is arranged on the first float rod 31 in a liftable mode, the second mounting hole 201 is arranged on the second float rod 32 in a liftable mode, when the pot cover 10 and the pot body 40 are closed in place, the second float rod 32 is located above the first float rod 31, when the pot body 40 is internally lifted, the first float rod 31 floats upwards and jacks the second float rod 32 towards the observation port 202, and the limiting rib 221 is used for limiting the second float rod 32 to be separated from the upper port. Meanwhile, the second float rod 32 can be limited by the limiting rib 221, the second float rod 32 is prevented from being separated from the upper port, and the installation stability of the second float rod 32 can be guaranteed.

Specifically, the hinge base 20 is used for connecting the pot cover 10 with the pot body 40, the pot cover 10 can horizontally rotate relative to the hinge base 20 and the pot body 40, and the hinge base 20 can drive the pot cover 10 to vertically turn relative to the pot body 40, so that when the pot cover 10 needs to be opened, the pot cover 10 is horizontally rotated to unlock, then the pot cover 10 turns relative to the pot body 40, when the pot cover 10 needs to be closed, the reverse operation can be performed, and the operation is simple and convenient. When the pot cover 10 is closed with the pot body 40 in place, the second float rod 32 is positioned above the first float rod 31. As shown in fig. 1 and 2, when there is no pressure in the pot body 40, the first float rod 31 and the second float rod 32 are in a natural drooping state due to self-gravity, and the top end of the second float rod 32 is far away from the observation port 202 and cannot be observed by a user; as shown in fig. 3 and 4, when the pressure is generated in the pot body 40, the first float rod 31 floats up and jacks up the second float rod 32 under the action of the pressure in the pot body 40, so that the top end of the second float rod 32 moves close to the observation port 202, and thus, the user can easily observe the top end of the second float rod 32 through the observation port 202, and further can know that the pressure is generated in the pot body 40, and under the state, the pot cover 10 is in a non-rotatable state and cannot be opened, so that the pressure pot can be effectively ensured to cook food under the pressure generating state, and the safety in use of the pressure pot is ensured.

Further, the second float rod 32 has an identification end surface facing the observation port 202, and the observation port 202 has an identification port corresponding to the identification end surface, the area of the identification port being larger than the area of the identification end surface. Thus, when the second float rod 32 floats upwards, the identification end face can be exposed at the identification port to the maximum extent, so that a user can observe the second float rod more conveniently. For example, the limiting rib 221 may be disposed at the middle of the upper port, and the distance between the outer circumference of the limiting rib 221 and the inner circumference of the second mounting hole 201 forms an identification opening.

Referring to fig. 2, 5 and 6, in one embodiment, the hinge base 20 includes a base body 21 and a face cover 22 that are covered with each other, the base body 21 is provided with a support cylinder 211 that is through from top to bottom, the face cover 22 is provided with a sleeve 222 that is inserted into and matched with the support cylinder 211, and the support cylinder 211 is communicated with an inner cavity of the sleeve 222 to form a second installation hole 201. Referring to fig. 4 and 7, the second float rod 32 includes a rod 322 and an identification head 321 disposed at one end of the rod 322, the rod 322 is disposed in the support cylinder 211 in a liftable manner, the identification head 321 is disposed in the sleeve 222 in a liftable manner, a boss 3211 is disposed on the periphery of the identification head 321, and when the second float rod 32 naturally droops, the boss 3211 is in limit contact with the top surface of the support cylinder 211. The second float rod 32 can be conveniently installed in the hinge base 20 by the matching of the sleeve 222 and the support cylinder 211, and meanwhile, the downward movement of the second float rod 32 can be limited by the matching of the boss 3211 and the support cylinder 211, so that the second float rod 32 is prevented from being separated from the bottom of the hinge base 20.

Further, at least two bosses 3211 are evenly arranged at intervals in the circumferential direction of the identification head 321, so that the supporting force applied to the second float rod 32 in the circumferential direction is more even. For example, as shown in fig. 7, bosses 3211 are symmetrically provided on opposite sides of the outer peripheral surface of the recognition head 321. Of course, more than two bosses 3211 may be provided according to actual needs.

Further, the outer circumference of the identification head 321 is further provided with a lug 3212, the lug 3212 is located on one side of the boss 3211 away from the rod body 322, and the lug 3212 and the boss 3211 are arranged in a staggered manner in the circumferential direction of the identification head 321, so that the second float rod 32 is kept balanced when being lifted. Therefore, the second float rod 32 can be more stable when being lifted, and the phenomenon that the identification end face of the identification head 321 is not displayed below the observation port 202 in the largest area due to the inclined inclination caused by the gravity difference is avoided. For example, as shown in fig. 7, two bosses 3211 are uniformly and at intervals on the outer peripheral surface of the adjacent portion of the identification head 321 and the rod 322, two lugs 3212 are uniformly and at intervals on the outer peripheral surface of one end of the identification head 321 away from the rod 322, and the bosses 3211 and the lugs 3212 are staggered.

Optionally, the rod 322 is provided with a rib 3221 extending in the axial direction at the outer circumference, and the outer edge of the rib 3221 contacts with the inner wall of the supporting cylinder 211. Thus, the direct contact between the outer circumferential surface of the rod body 322 and the inner wall of the supporting cylinder 211 can be avoided, the contact area between the rod body 322 and the supporting cylinder 211 can be effectively reduced, and further the friction force can be reduced, so that the lifting motion of the second float rod 32 is smoother, and the phenomenon that the second float rod 32 cannot jack up or fall down is avoided; meanwhile, the noise generated by the second float rod 32 in the lifting process can be effectively reduced.

Further, at least two ribs 3221 are circumferentially spaced and uniformly arranged on the rod body 322. Therefore, the circumferential stress of the rod body 322 is more uniform, and the lifting stability of the second float rod 32 is improved. For example, four ribs 3221 may be uniformly arranged at intervals in the circumferential direction of the rod body 322, and each rib 3221 is abutted against the inner wall of the supporting cylinder 211, so that the overall structure of the second float rod 32 is more symmetrical and the stress is more balanced.

In addition, the supporting cylinder 211 and the sleeve 222 can be connected in a sealing manner through a sealing element 212 to ensure good sealing performance. For example, as shown in fig. 4, the sealing member 212 may be sleeved on the periphery of the supporting cylinder 211, and when the sleeve 222 is inserted into the supporting cylinder 211, the end of the sleeve 222 presses the sealing member 212, thereby achieving a sealing connection. Alternatively, the inner peripheral surface of the sleeve 222 and the outer peripheral surface of the support cylinder 211 may be sealingly connected by the seal 212. The specific sealing connection manner is various and is not limited herein.

Further, the second float rod 32 is provided in a hollow rod shape. The weight of the second float rod 32 can be effectively reduced, and the second float rod 32 can be smoothly jacked up when the pressure cooker is started. Optionally, the second float rod is made of light plastic, so that the weight can be effectively reduced.
