[0033] Embodiment 1

[0034] The inner cover assembly of the present application is described in detail in this embodiment.

[0035] The inner cover assembly of this embodiment comprises an inner cover 1, a steel cover 2 and a heat preservation cover plate 3, the steel cover 2 is arranged between the inner cover 1 and the heat preservation cover plate 3, and the heat preservation cover plate 3 is clamped on the inner cover 1, as shown in Figure 1 . Preferably, the heat preservation cover plate 3 is provided with a first clasp 31 and a second clasp 32, the inner cover 1 is fixed with an opening cover clasp 5, and the inner cover 1 is further provided with a clamping groove 11, wherein the first clasp 31 is clamped with the opening cover clasp 5, and the second clasp 32 is clamped with the clamping groove 11, as shown in Figure 1 and Figure 3 . More preferably, a balance assembly 4 is arranged between the steel cover 2 and the heat preservation cover plate 3, the balance assembly 4 is used to keep the heat preservation cover plate 3 balanced, so as to keep the sealing ring 21 on the steel cover 2 and the heat preservation cover plate 3 in a sealed state, as shown in Figure 1 .

[0036] The inner cover assembly of this embodiment, since one end of the heat preservation cover plate 3 is clamped in the clamping groove 11 of the inner cover 1, and the other end is clamped on the opening cover clasp 5, i.e. the heat preservation cover plate 3 is fixed by two points, when opening the cover, the heat preservation cover plate 3 is easy to be separated from the inner cover 1, so as to enhance the user experience; but since the heat preservation cover plate 3 is fixed by two points, it is easy to cause the heat preservation cover plate 3 to deviate to either side of the two sides not fixed, so as to cause the heat preservation cover plate 3 to deviate in position, affecting the sealing between the sealing ring 21 of the steel cover 2 and the heat preservation cover plate 3. Further, the inner cover assembly of this embodiment is provided with the balance assembly 4 between the steel cover 2 and the heat preservation cover plate 3, during use, the position of the heat preservation cover plate 3 can be corrected by the balance assembly 4, so as to keep it balanced, so as to keep the sealing ring 21 on the steel cover 2 and the heat preservation cover plate 3 in a sealed state, so as to ensure the sealing of the inner cover assembly and the safety during use. That is, the inner cover assembly of this embodiment solves the technical problem that the heat preservation cover plate 3 is easy to deviate in the prior art, affecting the sealing between the steel cover and the heat preservation cover plate.

[0037] According to a preferred embodiment, one end of the balancing assembly 4 is fixed to the steel cover 2, and the other end of the balancing assembly 4 is in contact with the heat preservation cover plate 3 and keeps the heat preservation cover plate 3 balanced, as shown in Figure 1 、 Figure 2 、 Figure 4 and Figure 5 . Alternatively, one end of the balancing assembly 4 is fixed to the heat preservation cover plate 3, and the other end of the balancing assembly 4 is in contact with the steel cover 2 and keeps the heat preservation cover plate 3 balanced. In the preferred technical solution of the inner cover assembly of the present embodiment, the balancing assembly 4 can be fixed to the steel cover 2 or the heat preservation cover plate 3. Through the balancing assembly 4, a force can be applied to the heat preservation cover plate 3, so that the circumferential direction of the heat preservation cover plate 3 is uniformly stressed, the heat preservation cover plate 3 is kept balanced, and the problem of deviation of the heat preservation cover plate 3 is avoided.

[0038] According to a preferred embodiment, the steel cover 2 is provided with a sealing ring 21 and a sealing ring support 22, and the sealing ring support 22 is fixed to the steel cover 2 and used to fix the sealing ring 21, as shown in Figure 2 . Preferably, the sealing ring support 22 can be fixed to the steel cover 2 by one or more of screw fixing connection, riveting and buckle connection. As shown in Figure 1 、 Figure 2 、 Figure 4 and Figure 5 , the sealing ring 21 is buckled between the steel cover 2 and the sealing ring support 22, and then fixed through the fixed connection between the sealing ring support 22 and the steel cover 2, so as to realize the fixation of the sealing ring 21 and ensure the stability of the sealing ring 21 during use.

[0039] According to a preferred embodiment, the balancing assembly 4 is fixed between the steel cover 2 and the sealing ring support 22, and the balancing assembly 4 is in contact with the edge side of the heat preservation cover plate 3, as shown in Figure 1 、 Figure 4 and Figure 5 . The edge side referred to in the preferred technical solution of the present embodiment refers to the part of the heat preservation cover plate 3 located outside the sealing ring 21, as shown in Figure 4 and Figure 5 . Since the strength of the heat preservation cover plate 3 near the edge side is higher, the balancing assembly 4 of the inner cover assembly of the preferred technical solution of the present embodiment is in contact with the edge side of the heat preservation cover plate 3, which can further improve the balance stability of the heat preservation cover plate 3 and the flatness of the heat preservation cover plate 3, thereby further improving the sealing between the sealing ring 21 and the heat preservation cover plate 3. On the other hand, since the sealing ring 21 is close to the edge side of the heat preservation cover plate 3, the balancing assembly 4 is in contact with the edge side of the heat preservation cover plate 3, which ensures the balance and flatness of the edge side of the heat preservation cover plate 3, and is more conducive to maintaining the sealing between the sealing ring 21 and the heat preservation cover plate 3.

[0040] According to a preferred embodiment, the balancing assembly 4 comprises an elastic member 41 and a balancing column 42, one end of the elastic member 41 is fixed to the steel cover 2, the other end of the elastic member 41 is connected with the balancing column 42, the balancing column 42 is clamped in the sealing ring support 22, and when the inner cover assembly is closed on the pot body, the elastic member 41 moves in the direction of increasing elastic force, and the end of the balancing column 42 contacts the heat preservation cover plate 3; when the inner cover assembly is separated from the pot body, the elastic member 41 moves in the direction of decreasing elastic force, as shown in Figure 4 and Figure 5 Preferably, the elastic member 41 is a spring or an elastic rubber block. When the inner cover assembly of the preferred technical solution of the present embodiment is closed on the pot body, the elastic member 41 moves in the direction of increasing elastic force, so that the movement of the elastic member 41 can drive the balancing column 42 to move and make the end of the balancing column 42 contact the heat preservation cover plate 3, so that the position of the heat preservation cover plate 3 can be corrected to keep balance, and then the sealing state between the sealing ring 21 on the steel cover 2 and the heat preservation cover plate 3 can be maintained.

[0041] On the other hand, when the inner cover assembly of the preferred technical solution of the present embodiment is separated from the pot body, due to the elastic effect of the elastic member 41, the balancing column 42 is pushed to apply a force to the heat preservation cover plate 3, and when the pressure in the electric pressure cooker is reduced, the heat preservation cover plate 3 falls down under the joint action of its own weight and the force applied by the balancing assembly 4, so that the falling down of the heat preservation cover plate 3 can be accelerated.

[0042] According to a preferred embodiment, the number of balancing assemblies 4 is multiple, and the balancing assemblies 4 are uniformly distributed along the circumferential direction of the steel cover 2 or the heat preservation cover plate 3. Preferably, the number of balancing assemblies 4 is at least three. More preferably, the number of balancing assemblies 4 is three, as shown in Figure 2 The inner cover assembly of the preferred technical solution of the present embodiment, the number of balancing assemblies 4 is multiple, which can enhance the uniformity of the stress (the force applied by the balancing assembly 4) in the circumferential direction of the heat preservation cover plate 3, so that the balance stability of the heat preservation cover plate 3 and the flatness of the heat preservation cover plate 3 can be further improved to improve the sealing between the sealing ring 21 and the heat preservation cover plate 3.
