[0050] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0051] like Figures 1 to 5 As shown, according to the first aspect of the embodiment of the present disclosure, a pot cover assembly 100 is proposed, including: a cover body 110, used to cover or open the pot mouth, and the cover body 110 is provided with a mounting hole 1101; a float part 120, movably arranged in the mounting hole 1101, the float part 120 has a mating end 1201 and a free end 1202, the mating end 1201 is used to conduct or cut off one end of the mounting hole 1101, and the free end 1202 is arranged close to the other end of the mounting hole 1101, and the float part 120 is a telescopic structure so that the distance between the free end 1202 and the mating end 1201 can be adjusted; a limiting part 130, which is arranged in the mounting hole 1101, along the conducting direction of the mounting hole 1101, the mating end 1201 and the free end 1202 are respectively located on both sides of the limiting part 130, and the limiting part 130 is used to limit the distance between the free end 1202 and the mating end 1201.

[0052] The pot cover assembly 100 provided in the embodiment of the present disclosure includes a cover body 110, a float part 120 and a limiting part 130, wherein the cover body 110 is provided with a mounting hole 1101, and the mounting hole 1101 provides a space for the installation of the float part 120 and the limiting part 130; accordingly, the float part 120 is movably arranged in the mounting hole 1101 and is a telescopic structure, so that the float part 120 can adjust the position of the mating end 1201 and the free end 1202 by moving along the conducting direction of the mounting hole 1101 on the one hand, and can also adjust the distance between the free end 1202 and the mating end 1201 by telescopic deformation on the other hand, so that the float part 120 has a high flexibility of movement, which is convenient for adjusting the position of the mating end 1201 and the free end 1202 during use; the aforementioned mating end 1201 is used to conduct or cut off the mounting hole 1101. One end of the hole 1101, namely the mating end 1201, can abut against the cover body 110 and block one end of the mounting hole 1101, thereby cutting off the mounting hole 1101, or can be separated from the cover body 110 and open one end of the mounting hole 1101, thereby connecting the mounting hole 1101, and the aforementioned free end 1202 is arranged close to the other end of the mounting hole 1101 and can be used to extend or retract into the other end of the aforementioned mounting hole 1101; the aforementioned limiting portion 130 is arranged in the mounting hole 1101, and the mating end 1201 and the free end 1202 are respectively located on both sides of the limiting portion 130 along the conducting direction of the mounting hole 1101, so that based on the setting of the limiting portion 130, the distance between the free end 1202 of the float portion 120 and the mating end 1201 can be limited, thereby avoiding contact between the free end 1202 and the mating end 1201.

[0053] In practical applications, the pot cover assembly 100 provided in the embodiment of the present disclosure can be arranged on the pot body assembly 200 of the pressure cooking device or used as a component of the pressure cooking device, wherein the cover body portion 110 can be used to cover the pot mouth of the aforementioned pot body assembly 200 to enclose a cooking cavity with the aforementioned pot body assembly 200; Figure 2 As shown, during the process of pressure cooking, the pressure in the cooking cavity can act on the float portion 120, and the float portion 120 will move along the mounting hole 1101 of the cover body 110 accordingly, so that the mating end 1201 of the float portion 120 contacts the cover body 110 and correspondingly cuts off one end of the mounting hole 1101, thereby preventing the cooking cavity from communicating with the external environment through the mounting hole 1101, so as to ensure that the pressure in the cooking cavity is stable, and the free end 1202 of the float portion 120 can extend out of the other end of the mounting hole 1101, so as to prompt the user of the pressure state of the cooking cavity; Figure 3As shown, in the aforementioned situation, if the free end 1202 of the float portion 120 is subjected to an external force and has a movement tendency to retract into the mounting hole 1101, the float portion 120 can offset the displacement of the free end 1202 by compressing and deforming itself, and based on the setting of the limiting portion 130, it can also prevent the distance between the free end 1202 and the mating end 1201 from being too small, and avoid the free end 1202 and the mating end 1201 from contacting each other due to compression deformation, thereby preventing the mating end 1201 from changing its position and avoiding the mounting hole 1101 from being turned on during pressure cooking, which is beneficial to reducing the probability of high-temperature medium in the cooking cavity being released to the outside through the mounting hole 1101 while ensuring the stability of the internal pressure of the cooking cavity, thereby reducing the risk of scalding to users, improving the safety of the pressure cooking process, and improving the user experience of the product.

[0054] It can be understood that the aforementioned high temperature medium can be but is not limited to high temperature gas, steam, high temperature liquid and the like.

[0055] It should be noted that in the conventional technology, the float of the pressure cooking appliance is usually a rigid structure, so when pressure is generated in the cooking cavity and one end of the float is forced to close the mounting hole, if the end of the float extending outside the cooking cavity is acted upon by an external force and has a tendency to retract into the mounting hole, the float as a whole will move along the mounting hole, causing the mounting hole to switch from a closed state to a conductive state, causing the cooking cavity to release pressure and release high-temperature medium to the external environment through the mounting hole. If the aforementioned external force is applied manually by the user, the user may be easily scalded, affecting the safe performance of pressure cooking. Compared with the aforementioned conventional technology, the pot cover assembly 100 provided in the embodiment of the present disclosure is based on the aforementioned setting and can utilize the telescopic deformation ability of the float portion 120 to offset the displacement of the free end 1202 and avoid contact between the free end 1202 and the mating end 1201 due to compression deformation, thereby avoiding conduction of the mounting hole 1101 caused by the position change of the mating end 1201, which is beneficial to ensuring the stability of the internal pressure of the cooking cavity while reducing the probability of the high-temperature medium in the cooking cavity being released to the outside through the mounting hole 1101, thereby reducing the risk of scalding to the user, improving the safety of the pressure cooking process, and helping to improve the user experience of the product.

[0056] It is understandable that if Figures 2 to 4 As shown, the pot cover assembly 100 provided in the embodiment of the present disclosure is based on the above-mentioned setting, and the float part 120 can have but is not limited to the first working state, the second working state and the third working state, wherein, Figure 2 As shown, when the float portion 120 is in the first working state, the mating end 1201 abuts against the cover portion 110 to block one end of the mounting hole 1101, and the free end 1202 extends out of the other end of the mounting hole 1101; Figure 3As shown, when the float portion 120 is in the second working state, the mating end 1201 abuts against the cover portion 110 to close one end of the mounting hole 1101, and the free end 1202 is retracted into the other end of the mounting hole 1101; Figure 4 As shown, when the float portion 120 is in the third working state, the mating end 1201 is separated from the cover body portion 110 to conduct the mounting hole 1101, and the free end 1202 is retracted into the other end of the mounting hole 1101; the switching between the aforementioned working states can be achieved by adjusting the position of the float portion 120 along the conducting direction of the mounting hole 1101 or the force conditions at both ends of the float portion 120.

[0057] like Figures 1 to 5 As shown, taking the pot cover assembly 100 provided in the embodiment of the present disclosure as an example when it is applied to a pressure cooking appliance, the aforementioned mounting hole 1101 can be opened along the thickness direction of the cover body 110, so that when the cover body 110 covers the pot mouth, the conducting direction of the mounting hole 1101 and the extending direction of the float part 120 can maintain a high consistency with the gravity direction, wherein the free end 1202 can be arranged close to the outer end of the mounting hole 1101, and the mating end 1201 can be arranged close to the inner end of the mounting hole 1101. It can be understood that the mounting hole 1101 The outer end of the mounting hole 1101 is the end away from the cooking cavity when the cover body 110 covers the pot mouth, and the inner end of the mounting hole 1101 is the end close to the cooking cavity when the cover body 110 covers the pot mouth. Based on the above arrangement, the float portion 120 can generate a lifting displacement under the action of the pressure difference between the cooking cavity and the external environment, thereby facilitating the on-off control of the inner end of the mounting hole 1101 by the mating end 1201, and facilitating the free end 1202 to extend or retract into the outer end of the mounting hole 1101 to reflect the pressure condition in the cooking cavity. Accordingly, during the pressure cooking process, before the pressure in the cooking chamber is increased, the float portion 120 may be in the aforementioned third working state; when the pressure in the cooking chamber rises to a level that can cause the float portion 120 to overcome resistance and generate an upward movement, the float portion 120 may switch from the aforementioned third working state to the aforementioned first working state, and may use the free end 1202 to prompt the user of the pressure condition in the cooking chamber; when the float portion 120 is in the first working state, if the free end 1202 is acted upon by an external force and has a movement tendency to retract into the outer end of the mounting hole 1101, the float portion 120 may use its own compression deformation to offset the displacement of the free end 1202 by means of compression deformation, and switch from the aforementioned first working state to the aforementioned second working state, thereby preventing the mating end 1201 from changing position and avoiding the mounting hole 1101 from being turned on when the pressure in the cooking chamber is high.

[0058] It can be understood that the float portion 120 can be an elastic telescopic structure or a non-elastic telescopic structure; wherein, when the float portion 120 is an elastic telescopic structure, the float portion 120 can have good deformation recovery ability, which is conducive to improving the convenience of switching the working state of the float portion 120 and facilitating the reuse of the float portion 120. For example, when the float portion 120 is in the aforementioned second working state, if the aforementioned external force applied to the free end 1202 is released, the float portion 120 can be restored to the aforementioned first working state; when the float portion 120 is a non-elastic telescopic structure, for example, when the float portion 120 can be a flexible telescopic structure or a non-elastic mechanical telescopic mechanism such as a telescopic rod, the float portion 120 can have a lower telescopic deformation resistance, which is conducive to further reducing the force on the mating end 1201 during the telescopic process, and then the position stability of the mating end 1201 can be further ensured during the process of switching the float portion 120 from the aforementioned first working state to the second working state.

[0059] like Figures 1 to 4 As shown, in some feasible examples, the limiting portion 130 and the cover portion 110 are an integrated structure, so that the connection strength between the limiting portion 130 and the cover portion 110 can be improved.

[0060] like Figure 3 As shown, in some examples, the minimum distance between the side of the limiting portion 130 facing the free end 1202 and the mating end 1201 is a first distance L1; the float portion 120 is provided with a first positioning member 126, and the first positioning member 126 is used to abut against the side of the limiting portion 130 facing the free end 1202. When the float portion 120 is in an extreme compression state, the distance between the first positioning member 126 and the mating end 1201 is a second distance; the first distance L1 is greater than the second distance.

[0061] In this technical solution, the float part 120 may be provided with a first positioning member 126, and the first distance L1 may be set to be greater than the second distance. It is understood that during use, the float part 120 may generate a displacement or expansion along the conducting direction of the mounting hole 1101. During the displacement or expansion process, the mating end 1201 may be close to or away from the cover part 110 and the limiting part 130, and as Figure 2 and Figure 3As shown, the mating end 1201 is in the position closest to the limiting portion 130 when it abuts the cover body 110 and cuts off one end of the mounting hole 1101. Accordingly, when in the aforementioned position, the distance between the limiting portion 130 and the mating end 1201 on the side facing the free end 1202 is the aforementioned first distance. At the same time, since the float portion 120 is a telescopic structure, the float portion 120 will have a corresponding telescopic limit. The aforementioned limit compression state refers to a state in which the float portion 120 is at its smallest length in the telescopic direction without being limited by the amount of compression applied externally and without causing failure.

[0062] Therefore, based on the above-mentioned setting of the technical solution, on the one hand, the float portion 120 can utilize the first positioning member 126 to cooperate with the limiting portion 130 during the movement to constrain the movement stroke of the free end 1202, thereby limiting the distance between the matching end 1201 and the free end 1202, avoiding contact between the matching end 1201 and the free end 1202, and reducing the risk of displacement of the matching end 1201 when the pressure in the cooking chamber is high; on the other hand, based on the setting of the size relationship between the above-mentioned first distance L1 and the second distance, the telescopic range of the float portion 120 in actual application can be further constrained and limited, and the float portion 120 can be prevented from reaching the ultimate compression state during use, and the float portion 120 can maintain a certain margin in the compression performance, thereby reducing the rigidity of the float portion 120 during use, and then if the free end 1202 is subjected to external force and retracts into the safety valve, the float portion 120 can be prevented from reaching the ultimate compression state during use. On the other hand, when the pressure in the cooking chamber is high, if the free end 1202 is acted upon by an external force and is displaced into the mounting hole 1101, the first positioning member 126 may abut against the limiting member 130 when the displacement reaches a certain level, and then utilize the supporting effect of the limiting member 130 to offset the external force, further preventing the external force from being transmitted to the mating end 1201 through the structure of the float member 120, which is beneficial to further ensure the cut-off effect of the mating end 1201 on the mounting hole 1101, reduce the risk of the mounting hole 1101 being turned on during pressure cooking, and improve the safety of the pressure cooking process.

[0063] like Figures 2 to 5As shown, in some examples, the float portion 120 includes: a base 121, which is arranged on the cover body 110 and is located at one end of the mounting hole 1101, and the base 121 is provided with a matching hole, and the matching hole is connected to the mounting hole 1101; a float body 122, which is movably penetrated in the matching hole; a sealing member 123, which is sleeved on one end of the float body 122 and is used to cover or open the matching hole; an elastic telescopic member 124, which is connected to the other end of the float body 122, and the elastic telescopic member 124 is movably penetrated in the mounting hole 1101; wherein the matching end 1201 is formed on the sealing member 123, and the free end 1202 is located at one end of the elastic telescopic member 124 away from the float body 122.

[0064] In this technical solution, the float part 120 may include a base 121, a float body 122, a sealing member 123 and an elastic member 124; wherein the base 121 is arranged on the aforementioned cover body 110 and is located at one end of the mounting hole 1101, and the base 121 is provided with a matching hole connected to the mounting hole 1101, so that the base 121 can partially cover the corresponding end of the mounting hole 1101; the float body 122 is penetrated in the aforementioned matching hole and can move relative to the matching hole, so that the float body 122 can generate a movement relative to the matching hole. The seal 123 is sleeved on one end of the float body 122 and has the mating end 1201, so that the seal 123 can move synchronously with the float body 122 and cover or open the mating hole, and then realize the on-off state control of one end of the mounting hole 1101 by switching the opening and closing state of the mating hole, and ensure the airtightness of the mating hole when covering the mating hole, further reduce the risk of high-temperature medium overflow in the cooking cavity, and provide more reliable guarantee for the pressure stability of the cooking cavity.

[0065] The elastic telescopic member 124 is connected to the end of the float body 122 away from the sealing member 123, and is elastically and telescopically arranged in the mounting hole 1101. The free end 1202 is located at the end of the elastic telescopic member 124 away from the float body 122. Therefore, in practical applications, the float part 120 can achieve telescopic deformation based on the setting of the elastic telescopic member 124. Then, when the free end 1202 is subjected to external force and has a movement tendency to retract into the mounting hole 1101, the elastic telescopic member 124 can offset the free end 1202 by elastic compression deformation. The displacement of 202 prevents the mating end 1201 from producing synchronous movement. At the same time, the elastic telescopic member 124 can store energy during the compression process to absorb the aforementioned external force, which is beneficial to further reduce the force on the mating end 1201 and provide reliable guarantee for stabilizing the position of the mating end 1201. The elastic telescopic member 124 can release energy and restore deformation after the aforementioned external force is released, so that the free end 1202 can extend out of the mounting hole 1101, which is convenient for reminding the user of the pressure status in the cooking cavity during the pressure cooking process, which is beneficial to improving the user experience of the product.

[0066] It can be understood that the aforementioned free end 1202 is located at the end of the elastic telescopic member 124 away from the float body 122, and the end of the elastic telescopic member 124 away from the float body 122 may be the free end 1202, or the end of the elastic telescopic member 124 away from the float body 122 may be provided with other components of the float portion 120, and the aforementioned free end 1202 is formed on the aforementioned other components.

[0067] In some examples, along the conducting direction of the mounting hole 1101 , two ends of the elastic stretchable member 124 are respectively located on two sides of the limiting portion 130 , and the limiting portion 130 is used to limit the distance between the two ends of the elastic stretchable member 124 .

[0068] In this technical solution, along the conducting direction of the mounting hole 1101, the two ends of the elastic telescopic member 124 are respectively located on both sides of the limiting portion 130, and the end of the elastic telescopic member 124 away from the float body 122 is the aforementioned free end 1202. Accordingly, the limiting portion 130 can limit the distance between the free end 1202 and the mating end 1201 by limiting the distance between the two ends of the elastic telescopic member 124. Based on the aforementioned arrangement, the length of the elastic telescopic member 124 in the conducting direction of the mounting hole 1101 can be increased, and the length proportion of the elastic telescopic member 124 in the extending direction of the float portion 120 can be increased, thereby improving the telescopic performance of the float portion 120, which is beneficial to further reducing the structural rigidity of the float portion 120, and is beneficial to further improving the ability of the float portion 120 to offset the displacement of the free end 1202 and absorb external force in actual applications, providing further guarantee for improving the position stability of the mating end 1201.

[0069] It can be understood that, in this technical solution, the first positioning member 126 can be arranged on the elastic telescopic member 124 .

[0070] like Figures 2 to 4 As shown, in some examples, the float portion 120 also includes: a float top rod 125, connected to the elastic telescopic member 124, and a free end 1202 is formed on the float top rod 125; a first positioning member 126, arranged on the float top rod 125, and the first positioning member 126 is used to abut against the side of the limiting portion 130 facing the free end 1202; wherein, when the first positioning member 126 abuts against the side of the limiting portion 130 facing the free end 1202, a gap is formed between the float top rod 125 and the float body 122.

[0071] In this technical solution, the float part 120 may further include a float top rod 125 and a first positioning member 126, wherein the float top rod 125 is connected to the aforementioned elastic telescopic member 124 and the aforementioned free end 1202 is formed on the float top rod 125, and the first positioning member 126 is arranged on the float top rod 125. It can be understood that compared with the elastic telescopic member 124, the aforementioned float top rod 125 can be a rigid structure, that is, the elasticity of the float top rod 125 is smaller and lower than the elastic telescopic member 124, so that the float top rod 125 is not easy to deform under the action of external force, and has good structural stability and reliability. In practical applications, the probability of structural damage to the float part 120 can be reduced, and the service life of the float part 120 can be extended. In addition, the float top rod 125 can provide good supporting conditions for the first positioning member 126, which is conducive to maintaining the stability of the posture of the first positioning member 126, thereby ensuring reliable cooperation between the first positioning member 126 and the limiting portion 130. At the same time, when the first positioning member 126 abuts against the limiting portion 130 on the side facing the free end 1202, a gap can be formed between the float top rod 125 and the float body 122, so that when the distance between the free end 1202 and the mating end 1201 is small, rigid contact between the float top rod 125 and the float body 122 can be avoided, which is beneficial to further ensure the position stability of the mating end 1201 during the pressure cooking process, and further when the pressure in the cooking chamber is high, it can further prevent the mounting hole 1101 from being connected, which is beneficial to ensure the safe and stable progress of the pressure cooking process.

[0072] In some feasible examples, the first positioning member 126 and the float top rod 125 may be an integrated structure, so as to improve the connection strength between the first positioning member 126 and the float top rod 125 .

[0073] like Figures 2 to 4As shown, in some examples, the float portion 120 also includes: a second positioning member 127, which is arranged on the float top rod 125, the second positioning member 127 is used to abut the side of the limiting portion 130 facing the mating end 1201, and the elastic telescopic member 124 is located between the second positioning member 127 and the float body 122; wherein, along the conducting direction of the mounting hole 1101, the distance between the first positioning member 126 and the second positioning member 127 is greater than the distance between the two sides of the limiting portion 130.

[0074] In this technical solution, the float portion 120 may further include a second positioning member 127 arranged on the float top rod 125. Along the conducting direction of the mounting hole 1101, the first positioning member 126 and the second positioning member 127 are respectively located on both sides of the lower inner portion, and the second positioning member 127 is used to abut against the side of the limiting portion 130 facing the mating end 1201. Accordingly, the elastic telescopic member 124 may be arranged between the second positioning member 127 and the float body 122, and the distance between the first positioning member 126 and the second positioning member 127 is arranged to be greater than the distance between the two sides of the limiting portion 130. Therefore, based on the above-mentioned arrangement, on the one hand, the float portion 120 can further utilize the matching relationship between the second positioning member 127 and the limiting portion 130 to constrain the maximum distance between the free end 1202 and the matching end 1201, thereby preventing the float top rod 125 from extending too much during use, which is beneficial to further reduce the probability of the float top rod 125 being accidentally touched; on the other hand, the second positioning member 127 can cooperate with the float body 122 to further constrain and limit the telescopic range of the elastic telescopic member 124 during use, which is beneficial to improve the stability and reliability of the elastic telescopic member 124 during the telescopic process, reduce the probability of the elastic telescopic member 124 getting stuck during the telescopic process, and provide a more reliable guarantee for the telescopic performance of the float portion 120.

[0075] like Figure 2 As shown, it can be understood that, by setting the distance between the first positioning member 126 and the second positioning member 127 to be greater than the distance between the two sides of the limiting portion 130 along the conducting direction of the mounting hole 1101, the float top rod 125 can have a range of motion as shown by the dimension line L2 in the conducting direction of the mounting hole 1101, thereby ensuring the mobility of the free end 1202 and the telescopic ability of the float portion 120. Accordingly, in order to ensure that a gap is formed between the float top rod 125 and the float body 122 when the first positioning member 126 abuts against the side of the limiting portion 130 facing the free end 1202, the distance L3 between the end of the float top rod 125 close to the float body 122 and the float body 122 can be set to be greater than the aforementioned range of motion L2 when the float portion 120 is in the first working state.

[0076] In some feasible examples, the second positioning member 127 and the float top rod 125 may be an integrated structure, so as to improve the connection strength between the second positioning member 127 and the float top rod 125 .

[0077] like Figures 2 to 4 As shown, in some examples, one end of the float top rod 125 close to the float body 122 is penetrated by the elastic telescopic member 124 .

[0078] In this technical solution, a float top rod 125 can be arranged close to one end of the float body 122 and passed through the elastic telescopic part 124. Based on the above arrangement, the part of the float top rod 125 passing through the elastic telescopic part 124 can further constrain the posture of the elastic telescopic part 124 during the telescopic deformation process, further reduce the probability of the elastic telescopic part 124 getting stuck during use, and help provide further guarantee for the smooth telescopic extension and retraction of the float part 120.

[0079] In some examples, the stiffness coefficient of the elastic telescopic member 124 satisfies:

[0080]

[0081] In the above formula (1), k is the stiffness coefficient of the elastic expansion member 124, p min is the minimum working pressure of the pressure cooking appliance, A is the positive projection area of ​​the seal 123 in the projection plane perpendicular to the gravity direction, G0 is the gravity of the elastic elastic member 124, G1 is the gravity of the float body 122, G2 is the gravity of the seal 123, x max is the maximum expansion and contraction amount of the elastic expansion member 124.

[0082] In this technical solution, when the pot cover assembly 100 is applied to a pressure cooking appliance, the progress coefficient of the elastic telescopic member 124 can be set to satisfy the above formula (1), thereby avoiding that the progress coefficient of the elastic telescopic member 124 is too large, which is beneficial to preventing the elastic telescopic member 124 from generating excessive elastic force when compressed, and further reducing the elastic force exerted by the elastic telescopic member 124 on the float body 122, preventing the float body 122 and the sealing member 123 from overcoming the pressure in the cooking cavity and being displaced under the action of the aforementioned elastic force, which is beneficial to ensuring the shutoff effect of the mating end 1201 on the mounting hole 1101, further ensuring the pressure stability in the cooking cavity, and reducing the risk of overflow of the high-temperature medium in the cooking cavity.

[0083] It is understandable that pressure cooking appliances usually have a rated working pressure range, and the aforementioned minimum working pressure is also the minimum pressure of the cooking cavity of the pressure cooking appliance when performing pressure cooking. In combination with the above, when the pot cover assembly 100 is applied to the pressure cooking appliance, the mounting hole 1101 can be arranged to be opened along the thickness direction of the cover body 110, so that when the cover body 110 and the pot body assembly 200 enclose the aforementioned cooking cavity, the extension direction of the float part 120 and the gravity direction can have a high consistency, so that based on the arrangement of the aforementioned sealing member 123, the product of the pressure in the cooking cavity and the orthographic projection area A of the sealing member 123 in the projection plane perpendicular to the gravity direction can represent the force exerted by the air pressure in the cooking cavity on the float part 120 along the gravity direction.

[0084] like Figures 2 to 4 As shown, in some examples, the elastic telescopic member 124 is made of silicone; or the elastic telescopic member 124 is a spring or a spring.

[0085] In this technical solution, the elastic telescopic part 124 can be made of silicone, so that the elastic telescopic part 124 can have good telescopic deformation ability while having good molding convenience, which is beneficial to setting the structural shape of the elastic telescopic part 124 in combination with actual needs during the production of the cover body assembly, and then facilitating the formation of a stable and reliable matching relationship between the elastic telescopic part 124 and the mounting hole 1101, thereby improving the stability of the float part 120 during the telescopic process.

[0086] Alternatively, the elastic telescopic member 124 may be a spring, so that the elastic telescopic member 124 has good telescopic deformation capability and good replaceability, which is beneficial to reducing the use cost and repair and maintenance cost of the pot cover assembly 100.

[0087] Alternatively, the elastic telescopic member 124 may be a spring sheet, so that the elastic telescopic member 124 has good telescopic deformation capability and good replaceability, which is beneficial to reducing the use cost and repair and maintenance cost of the pot cover assembly 100.

[0088] like Figures 1 to 5 As shown, in some examples, the pot cover assembly 100 further includes: a handle portion 140 disposed on the cover body 110 .

[0089] In this technical solution, the pot cover assembly 100 may further include a handle portion 140 disposed on the cover body portion 110 , thereby facilitating the user to operate the cover body assembly in actual applications, thereby further improving the ease of use of the pot cover assembly 100 .

[0090] It is understandable that the mating ends 1201 of the handle portion 140 and the float portion 120 may be located on two sides of the cover portion 110 , respectively.

[0091] like Figure 5 As shown, in some feasible examples, the pot cover assembly 100 may further include a sealing portion 150, which is disposed on the cover body 110. When the cover body 110 covers the pot mouth, the sealing portion 150 is located between the pot body assembly 200 and the cover body 110, so that the pot cover assembly 100 can further utilize the sealing portion 150 to seal the gap between the cover body 110 and the pot mouth, providing further reliable guarantee for the smooth progress of pressure cooking.

[0092] like Figure 5 As shown, according to the second aspect of the embodiment of the present disclosure, a pressure cooking device is proposed, including: a pot body assembly 200, which is formed with a pot mouth; and a pot cover assembly 100 as proposed in any one of the first aspects above, which is used to open or cover the pot mouth.

[0093] The pressure cooking device provided by the embodiment of the present disclosure includes a pot body assembly 200 and a pot cover assembly 100 as provided in any one of the first aspects above, and the cover body portion 110 can be used to cover the pot mouth of the aforementioned pot body assembly 200 to enclose a cooking cavity with the aforementioned pot body assembly 200; Figure 2 As shown, during the process of pressure cooking, the pressure in the cooking cavity can act on the float portion 120, and the float portion 120 will move along the mounting hole 1101 of the cover body 110 accordingly, so that the mating end 1201 of the float portion 120 contacts the cover body 110 and correspondingly cuts off one end of the mounting hole 1101, thereby preventing the cooking cavity from communicating with the external environment through the mounting hole 1101, so as to ensure that the pressure in the cooking cavity is stable, and the free end 1202 of the float portion 120 can extend out of the other end of the mounting hole 1101, so as to prompt the user of the pressure state of the cooking cavity; Figure 3 As shown, in the aforementioned situation, if the free end 1202 of the float portion 120 is subjected to an external force and has a movement tendency to retract into the mounting hole 1101, the float portion 120 can offset the displacement of the free end 1202 by compressing and deforming itself, and based on the setting of the limiting portion 130, it can also prevent the distance between the free end 1202 and the mating end 1201 from being too small, and avoid the free end 1202 and the mating end 1201 from contacting each other due to compression deformation, thereby preventing the mating end 1201 from changing its position and avoiding the mounting hole 1101 from being turned on during pressure cooking, which is beneficial to reducing the probability of high-temperature medium in the cooking cavity being released to the outside through the mounting hole 1101 while ensuring the stability of the internal pressure of the cooking cavity, thereby reducing the risk of scalding to users, improving the safety of the pressure cooking process, and improving the user experience of the product.

[0094] It can be understood that the aforementioned high temperature medium can be but is not limited to high temperature gas, steam, high temperature liquid and the like.

[0095] like Figure 5 As shown, in some feasible examples, the pot body assembly 200 may include a first pot body 210 and a second pot body 220, wherein the first pot body 210 is formed with the aforementioned pot mouth, and the second pot body 220 is formed with a receiving groove, and the first pot body 210 is arranged in the aforementioned receiving groove, that is, in actual application, the aforementioned first pot body 210 can form a cooking cavity with the cover body 110, and be used to receive food to be cooked, and the aforementioned second pot body 220 can be used as an outer pot to provide structural protection for the first pot body 210 and improve the aesthetics of the pressure cooking appliance.
