The lower end of the connecting portion 211 of the steel cover 210 is further provided with locking teeth, and the locking teeth can lock the pot cover 200 on the pot body 100, so that high pressure is formed during cooking of the pressure cooker, and the pot cover 200 cannot be opened, thereby forming an effect of high pressure cooking.

The high pressure formed during cooking of the pressure cooker generates upward thrust on the steel cover 210, because the steel cover 210 is locked on the cooker body 100, the steel cover 210 deforms at the highest pressure, the glass cover 240 is arranged on the upper cover 230 and is the upper surface, deformation of the steel cover 210 in the longitudinal direction can easily cause breakage of the glass cover 240 if being transmitted to the glass cover 240, in the embodiment, because the upper cover 230 and the steel cover 210 have the deformation gap 250 in the longitudinal direction, the deformation gap 250 can provide an abdicating space for upward deformation of the steel cover 210 in the longitudinal direction, deformation of the steel cover 210 in the longitudinal direction can not be transmitted to the upper cover 230, the glass cover 240 is attached to the upper surface of the upper cover 230, when the upper cover 230 is not influenced by deformation of the steel cover 210 in the longitudinal direction, the glass cover 240 cannot be naturally influenced, and thus the deformation of the steel cover 210 can not cause breakage of the glass cover 240.

The steel cover 210 deforms along with the rise of the pressure in the cooking cavity of the pot body 100, so that the deformation gap 250 is reduced relative to the upper cover 230, the larger the pressure in the cooking cavity is, the larger the deformation of the steel cover 210 is, and the smaller the deformation gap 250 is, when the pressure in the cooking cavity reaches the highest limit of the safety pressure of the pressure cooker, the steel cover 210 can be in contact with the upper cover 230, and the deformation gap 250 can still exist between the steel cover 210 and the upper cover 230. It should be noted that, as long as the cooking cavity is at normal pressure, that is, the steel cover 210 is not deformed, a deformation gap 250 exists between the steel cover 210 and the upper cover 230, which provides a yielding space for the deformation of the steel cover 210 to a certain extent, and does not exclude that the steel cover 210 will contact the upper cover 230 when deformed to a large extent.

The handle 260 is provided on the upper cover 230, the handle 260 is connected to the steel lid 210 on the lower side of the upper cover 230 through the upper cover 230 by a connecting member 270, and the handle 260 lifts the pot cover 200 and the pot body 100 such that the deformation gap 250 is reduced with respect to the upper cover 230. When the handle 260 lifts the lid 200 and the body 100, the steel lid 210 is the main stress component, which reduces the stress on the upper lid 230 and the possibility of the glass cover 240 being broken due to the deformation of the upper lid 230.

When the handle 260 is lifted, an upward pulling force is transmitted from the handle 260 to the connecting member 270, and then from the connecting member 270 to the steel cap 210. In this embodiment, the connecting member 270 is fixedly connected to the steel cap 210, so that the transmission of the tensile force can be achieved. In other alternative embodiments, the connecting member 270 may also be movably connected to the steel cap 210, for example, a through hole is formed in the steel cap 210, the lower end of the connecting member 270 passes through the through hole, a limiting structure with an outer diameter larger than the diameter of the through hole is disposed at the lower end of the connecting member 270, and when the connecting member 270 moves upwards, the limiting structure can abut against the lower surface of the steel cap 210, so that the connecting member 270 can also transmit the pulling force to the steel cap 210.

The steel cover 210 is provided with a fixing hole 212, and the lower end of the connecting piece 270 is detachably and fixedly connected with the steel cover 210 at the fixing hole 212.

Coupling member 270 floats upward relative to cover 230 and handle 260 as the pressure in the cooking chamber of pot 100 increases. I.e., the connection member 270 is fixedly connected to the upper cover 230 and the handle 260 so as not to be movable relative thereto, the connection member 270 can be moved up and down relative to the upper cover 230 and the handle 260. When the handle 260 is clamped with the upper cover 230, if the connecting piece 270 is fixedly connected with the handle 260, the connecting piece 270 moves upwards when the steel cover 210 deforms, an upward force is generated on the handle 260, the upward force is generated on the upper cover 230 by the handle 260 due to clamping of the handle 260 and the upper cover 230, the upper cover 230 may deform to cause the glass surface cover 240 to break, the connecting piece 270 can float upwards relative to the handle 260, the pushing force on the handle 260 is not generated when the connecting piece 270 floats upwards, and the possibility of breaking the glass surface cover 240 is reduced.

The handle 260 lifts the lid 200 and the pot body 100, and the connecting member 270 moves relative to the upper lid 230, so that the gap between the handle 260 and the upper lid 230 is increased. Thus, the handle 260 will not deform the upper cover 230, reducing the possibility of breakage of the glass panel.

The upper cover 230 is provided with a first mounting hole 231, the handle 260 is provided with a second mounting hole 261 corresponding to the first mounting hole 231, the first mounting hole 231 and the second mounting hole 261 are provided with a connecting piece 270 in a penetrating manner, the connecting column 213 penetrates into the first mounting hole 231, and a gap is formed between the connecting column 213 and the hole wall of the first mounting hole 231. This allows the link 270 to move up and down relative to the handle 260 and the upper cover 230 without transmitting force to the upper cover 230. In other alternative embodiments, there may be no gap between the connection column 213 and the hole wall of the first installation hole 231, for example, the connection is made by an elastic member, when the steel cover 210 deforms upward, the connection column 213 floats upward, and the elastic member deforms, so that the upper cover 230 and the handle 260 are not driven by the upward and downward floating of the connection column 213 to deform, and the possibility of deformation of the glass panel is reduced.

A limiting cap 271 is arranged at the upper end part of the connecting piece 270, and the outer diameter of the limiting cap 271 is larger than that of the second mounting hole 261; or a gasket is arranged between the limiting cap 271 and the handle 260, and the diameter of the gasket is larger than that of the second mounting hole 261. When the handle 260 is lifted, the limiting cap 271 or the gasket will abut against the handle 260, so that the handle 260 forms an upward force on the connecting member 270 and transmits the upward force to the steel cover 210, and the steel cover 210 is locked on the pot body 100 and transmits the force to the pot body 100, thereby lifting the pot body 100 and the pot cover 200.

As shown in fig. 2, an air release pipe 280 is fixedly disposed on the steel cap 210, a third mounting hole 232 is disposed on the upper cap 230, the air release pipe 280 passes through the third mounting hole 232, and a sealing member is disposed between the air release pipe 280 and the upper cap 230, and the sealing member can move up and down or deform relative to the upper cap 230. If the sealing element is rigidly connected with the upper cover 230, the deformation of the steel cover 210 drives the air release pipe 280 to move upwards, the upward movement of the air release pipe 280 drives the upper cover to deform, so that the glass surface cover 240 is broken, the sealing element can move up and down relative to the upper cover 230 or deform, so that the upward movement of the air release pipe 280 cannot drive the upper cover 230 to deform, and the possibility of breaking the glass surface cover 240 is reduced. In this embodiment, the sealing member is a sealing ring 233 having elasticity, and the vertical movement of the gas release pipe 280 deforms the sealing ring 233, so that the vertical movement of the gas release pipe 280 does not deform the upper cover 230, thereby reducing the possibility of breakage of the glass panel. The packing 233 can improve the sealing performance of the upper cover 230. In other alternative embodiments, the sealing member may be made of a rigid material, for example by increasing the male-female fit between the sealing member and the upper cover to achieve the sealing effect, while ensuring that the sealing member can move up and down relative to the upper cover.

The packing 233 includes an inner ring 234 and an outer ring 235, the inner ring 234 is coupled to the gas release pipe 280, the outer ring 235 is coupled to a side edge of the third mounting hole 232, and a thickness of the inner ring 234 is smaller than a thickness of the outer ring 235. Thus, the inner ring 234 is easily deformed, which is advantageous in that the upper cover 230 is not deformed when the air release pipe 280 moves up and down. The outer ring 235 is provided with a mounting groove, and the lateral edge of the third mounting hole 232 is embedded into the mounting groove, so that the sealing ring 233 is fixed on the upper cover 230, the sealing ring 233 is prevented from being separated from the upper cover 230 due to the up-and-down floating of the gas release pipe 280, and the sealing stability of the sealing ring 233 is improved.
