Description

[Technical Field]

[0001] The present application relates to the technical field of pressure cookers, and more particularly to pot lids and pressure cookers. [Background technology]

[0002] Pressure cookers are popular with a wide range of consumers due to their energy-saving, time-saving, and versatile cooking functions. By applying pressure to a liquid, the boiling point of the liquid increases, making it possible to improve the efficiency of cooking food.

[0003] A pressure cooker generally includes a pot body and a pot lid. To create a high-pressure effect, the pot lid and the pot body must be sealed and locked together to achieve a pressure seal. In the related art, a telescopic locking structure is provided on the pot lid of a pressure cooker to achieve a sealed lock between the pot lid and the pot body. While the telescopic locking structure is easy to operate during use, the locking member of the telescopic locking structure must slide along the radial direction of the pot lid, and jamming can easily occur during the sliding process of the locking member (especially if the locking member is large in volume), which can severely affect the normal use of the pot lid.

DETAILED DESCRIPTION OF THE INVENTION

[0030] The following detailed description of the embodiments of the present application is provided in the accompanying drawings, in which the same or similar reference numerals refer to the same or similar components or components having the same or similar functions. The embodiments are provided for illustrative purposes only and should not be construed as limiting the present application.

[0031] References herein to "one embodiment" or "example" or "example" mean that a particular feature, structure, or characteristic described with reference to the embodiment itself is included in at least one embodiment disclosed herein. The appearances of the phrase "in one embodiment" in various places in this specification are not necessarily all referring to the same embodiment.

[0032] One embodiment of the present application discloses a pot lid including a lid body 100, which includes a drive mechanism 140 and a plurality of movable insert plates 150, both of which are provided on the lid body 100. The plurality of movable insert plates 150 are provided along the circumferential direction of the lid body 100, and the movable insert plates 150 are slidable along the radial direction of the lid body 100.

[0033] Lid body 100 is formed with a plurality of guide mechanisms corresponding to a plurality of movable insertion plates 150, and the outer walls of movable insertion plates 150 engage with the corresponding guide mechanisms. Driving mechanism 140 drives movable insertion plate 150 to move along the radial direction of lid body 100 so that the outer walls of movable insertion plate 150 slide along the corresponding guide mechanisms and finally engage with pot body 200 from the inside thereof.

[0034] The pot lid according to the embodiment of the present application uses a movable insertion plate 150 that moves radially to engage and disengage with the pot body 200. When using the pot lid to seal the pot body 200, there is no need to control the relative positions of the pot lid and the pot body 200 in the circumferential direction, making operation more convenient. In the overall structure, the movable insertion plate 150 and the corresponding drive mechanism 140 are both located inside the pot lid, making the appearance of the pot lid similar to that of a normal pot lid. This makes it difficult for users to mistake the pot lid according to the present application and the pressure cooker structure to which the pot lid is applied for as a dangerous pressure vessel, effectively preventing users from feeling afraid of pressure cookers.

[0035] In addition, in the embodiments of the present application, the number of movable insert plates 150 provided on the pot lid is generally three or more. In one preferred embodiment, the multiple movable insert plates 150 are uniformly arranged along the circumferential direction of the lid body 100, so that after the multiple movable insert plates 150 and the pot body 200 are engaged with each other, the effect of uniform engagement along the circumferential direction of the pot body 100 can be achieved, improving the stability of the engagement.

[0036] This embodiment does not limit the specific structure of the movable insert plate 150, as long as it can lock the pot body 200 and the pot lid. Furthermore, since the movable insert plate 150 is plate-shaped, the overall thickness of the pot lid can be reduced. Accordingly, for a pressure cooker with the same volume, the volume of the pot body 200 can be increased by using the pot lid according to the embodiment of the present application, thereby better meeting the user's usage needs.

[0037] The present application does not limit the specific form of the drive mechanism 140, as long as it can drive the movable insertion plate 150 to move along the radial direction of the lid body 100. For example, the drive type of the drive mechanism 140 may be a rotary drive, a linear drive, or the like.

[0038] The guide mechanism in the present embodiment can engage with the outer wall of the movable insert plate 150. Compared with a guide mechanism provided inside the movable insert plate 150, the guide mechanism in the present embodiment can guide the movable insert plate 150 over a longer range and further improve the stability of the movable insert plate 150. The guide mechanism in the present embodiment can generally be configured in the form of a guide groove, and in use, the movable insert plate 150 is provided in the guide groove, with both side walls of the movable insert plate 150 facing the side walls of the guide groove.

[0039] As one embodiment of the present application, as shown in Figures 6 and 15, the movable insertion plate 150 includes a connection portion and an insertion portion, one end of the connection portion is connected to the drive mechanism 140 and the other end is connected to the insertion portion, the length of the insertion portion along the circumferential direction of the pot lid is longer than the length of the connection portion along the circumferential direction of the pot lid, the guide mechanism includes an inner guide groove and an outer guide groove arranged in order from the inside to the outside along the radial direction of the pot lid, and the outer wall of the connection portion engages with the inner guide groove, and the outer wall of the insertion portion engages with the outer guide groove.

[0040] To more clearly explain the structure of the movable insert plate 150, the structure of the movable insert plate 150 will be described as shown in Figures 6 and 15. As shown in the figures, the insertion portion of the movable insert plate 150 includes a first insertion portion 152 and a second insertion portion 154, and the connection portion of the movable insert plate 150 includes a first connection portion 151 and a second connection portion 153.

[0041] The guide mechanism in this embodiment includes an inner guide groove and an outer guide groove, which can respectively engage with the connecting portion and the inserting portion of the movable insert plate 150 in the radial direction of the pot lid. In this embodiment, the connecting portion and the inserting portion have different circumferential widths, forming a T-shaped structure. The inner guide groove and the outer guide groove can restrict the connecting portion and the inserting portion, which have different widths, respectively, thereby improving the stability of the movement of the movable insert plate 150.

[0042] In addition, the insertion portion in the embodiment of the present application has a longer length along the circumferential direction of the pot lid, which provides a larger engagement area when the insertion portion engages with the pot body 200, further improving the strength and stability of the engagement. Furthermore, by increasing the engagement area, the thickness of the movable insertion plate 150 can be reduced.

[0043] As an embodiment of the present application, as shown in Figures 1 and 8, the lid body 100 includes an outer lid 120 and an inner base 110, the outer lid 120 and the inner base 110 are engaged and connected, an accommodating cavity is formed between the outer lid 120 and the inner base 110, the inner guide groove is provided in the accommodating cavity, the outer guide groove penetrates the side wall of the accommodating cavity, and a driving mechanism 140 drives the insertion portion to slide along the outer guide groove, thereby allowing the insertion portion to be extended from the accommodating cavity or accommodated in the accommodating cavity.

[0044] In the embodiment of the present application, when there is no need to lock the pot lid to the pot body, the movable insert plate 150 can be positioned completely within the receiving cavity, and thus the movable insert plate 150 cannot be seen from the outside, improving the overall appearance of the pot lid; when the pot lid is covered and locked to the pot body 200, the movable insert plate 150 is locked to the inner wall of the pot body 200 from inside the pot body 200, and similarly, the movable insert plate 150 cannot be seen from the outside.

[0045] 1 and 7, in one embodiment of the present application, inner base 110 includes a reinforcing support member 111 and a guide support member 112, and guide support member 112 is provided on the upper side of reinforcing support member 111, and reinforcing support member 111 and guide support member 112 are each connected to outer lid 120. On the upper surface of guide support member 112, a plurality of first inner limiting bases 1121 are formed, which are spaced apart along the circumferential direction of the pot lid, and a plurality of first outer limiting bases 1122 are formed, which are spaced apart along the circumferential direction of the pot lid, and first outer limiting bases 1122 are located radially outward of first inner limiting base 1121.

[0046] The first inner limiters 1121 are divided into groups, each group including two first inner limiters 1121, and two first inner limiters 1121 in the same group are arranged opposite each other to define the inner guide groove. Two adjacent first outer limiters 1122 define the outer guide groove.

[0047] In this embodiment, the movable insertion plate 150 is slidably connected to the inner base 110, and the guide support member 112 of the inner base 110 is provided with a first inner limiting block 1121 and a first outer guide portion that are engaged with the movable insertion plate 150. The first inner limiting block 1121 and the first outer guide portion can be slidably engaged with the first connecting portion 151 and the first inserting portion 152 of the movable insertion plate 150, respectively, to provide a multi-guide effect for the movable insertion plate 150, thereby making the movement of the movable insertion plate 150 more stable. is connected to the driving disc 141, and the first inserting portion 152 can be extended from the lid body 100 to engage with the pot body 200. The movable insert plate 150 is divided into two parts, and the specific structure of the movable insert plate 150 can be reasonably designed according to different functions. As shown in Figures 6 and 15, the entire movable insert plate 150 has a structure similar to the letter "T." The first inserting portion 152 has a relatively large length in the circumferential direction of the pot lid, forming a large engaging area between the pot body 200 and the first inserting portion 152 and further increasing the engaging stability. The relatively small size of the first connecting portion 151 not only saves material but also facilitates the overall layout of the pot lid.

[0048] In this embodiment, the connection between the first connection portion 151 and the drive disk 141 may be realized by engagement between the pin shaft and the drive groove 1411 as shown in Figure 3, or the connection between the first connection portion 151 and the drive disk 141 may be realized by wedge-shaped engagement (engagement spring) between protrusions, as long as it is ensured that the rotation of the drive disk 141 drives the movable insertion plate 150 to expand and contract along the radial direction of the pot lid.

[0049] 5 and 7, the reinforcing support member 111 includes a central flat portion 1111, a reinforcing portion 1112, an edge flat portion 1113, and a sealing mounting ring 1114. The central flat portion 1111 is connected to the inner edge of the reinforcing portion 1112, and the outer edge of the reinforcing portion 1112 is connected to the edge flat portion 1113. The sealing mounting ring 1114 protrudes from the bottom surface of the edge flat portion 1113 and forms a gap with the outer edge of the edge flat portion 1113. The bottom end of the sealing mounting ring 1114 extends at an angle outward from the edge flat portion 1113. The pot lid further includes an elastic sealing ring 130 fitted on the outer surface of the sealing mounting ring 1114, and the upper end of the elastic sealing ring 130 abuts against the bottom surface of the edge flat portion 1113.

[0050] Since a conical structure has better structural strength than a planar structure, as shown in the figure, the reinforcing portion 1112 of the reinforcing support member 111 in this embodiment may be set to a conical shape to provide high structural strength. Of course, the embodiment of the present application is not limited thereto, and the reinforcing portion 1112 may be set to other shapes, such as an arc shape.

[0051] In another embodiment, in order to further improve the structural strength of the reinforcing support member 111, the central plane portion 1111 may be configured to be recessed at the inner edge of the reinforcing portion 1112 as shown in Fig. 5. Note that the conical sidewall of the reinforcing portion 1112 in this embodiment slopes upward from the outside to the inside as shown in Fig. 7.

[0052] The sealing attachment ring 1114 in this embodiment forms a certain angle, which can better support and secure the elastic sealing ring 130.

[0053] 8 and 13, in one embodiment of the present application, the outer cover 120 includes an outer plate 121, an attachment abutment portion 122, a first shielding ring 123, and a second shielding ring 124. It can be easily understood that the first shielding ring 123 and the second shielding ring 124 are both annular.

[0054] The outer plate 121 surrounds the mounting abutment portion 122, the bottom side of which protrudes toward the inner base 110 and is connected to the central flat portion 1111. The first shielding ring 123 and the second shielding ring 124 both protrude from the bottom of the outer plate 121, the first shielding ring 123 being positioned outside the second shielding ring 124, and the second shielding ring 124 facing the first outer limiting base 1122 in the axial direction of the pot lid.

[0055] The outer lid 120 includes an outer plate 121, an annular plate 127, and a plurality of second inner limiters 125, with the annular plate 127 and the second inner limiters 125 both protruding from the bottom surface of the outer plate 121. The second inner limiters 125 are arranged along the circumferential direction of the pot lid and are located inside the annular plate 127.

[0056] The multiple second inner limiting stands 125 are divided into multiple groups, each group including two second inner limiting stands 125, and the two second inner limiting stands 125 in the same group are arranged opposite each other to define the inner guide groove.

[0057] The annular plate 127 is formed with a plurality of outer guide grooves arranged along the circumferential direction of the annular plate 127 .

[0058] In this embodiment, the outer lid 120 is connected to the central plane portion 1111 on the reinforcing support member 111 of the inner base 110 via the mounting abutment portion 122, and is connected to the guide support member 112 via the outer plate 121 by screws arranged circumferentially around the axis of the pot lid, thereby improving the reliability of the connection between the outer lid 120 and the inner base 110.

[0059] In this embodiment, a first shielding ring 123 and a second shielding ring 124 are further provided, and the first shielding ring 123 is located outside the second shielding ring 124. Thus, when the movable insert plate 150 is in the retracted state, the second shielding ring 124 can shield the movable insert plate 150, and when the movable insert plate 150 is in the extended state, the first shielding ring 123 can shield the movable insert plate 150. As can be seen from Figures 1 and 7, there is a certain gap between the first shielding ring 123 and the second shielding ring 124.

[0060] As can be seen from the above, the movable insert plate 150 according to the embodiment of the present application may engage with either the outer cover 120 or the inner base 110 during installation. Naturally, the embodiment of the present application is not limited to this and can be reasonably designed according to actual needs. If a guide mechanism is provided on the outer cover 120, the number of parts of the pot lid can be reduced and the overall structure can be simplified.

[0061] As shown in FIG. 13, the movable insertion plate 150 engages with the outer cover, the outer cover is provided with a second inner limiting base 125, the annular plate 127 has an outer guide groove formed thereon, and there are second outer limiting bases 126 on both sides of the outer guide groove, so that the second outer limiting base 126 and the second inner limiting base 125 can engage with the second insertion portion 154 and the second connecting portion 153, respectively.

[0062] In one embodiment of the present application, the drive mechanism 140 includes a drive disc 141 and an operating unit 142. The drive disc 141 is rotatably mounted within the lid body 100. The operating unit 142 has a first end connected to the drive disc 141 and a second end extending from the top surface of the lid body 100. The drive disc 141 has a plurality of drive grooves 1411 extending along the circumferential direction, each of which corresponds to a plurality of movable insertion plates 150. The distance between each point in the drive groove 1411 and the axis of the pot lid gradually changes along the circumferential direction. One end of the movable insertion plate 150 is formed with an engagement portion 157, which is received in the drive groove 1411. By operating the operating unit 142, the drive disc 141 can be driven to rotate, and the movable insertion plate 150 can be driven to move radially around the lid body 100.

[0063] 3 and 14, the driving groove 1411 in this embodiment engages with the engaging portion 157 (generally designed as a pin shaft) of the movable insertion plate 150, and the engaging portion 157 can rotate relative to the driving groove 1411 or slide relative to the driving groove 1411. Because the distances between different parts of the driving groove 1411 and the axis of the driving disc 141 are different, when the driving disc 141 rotates, the driving groove 1411 can drive the movable insertion plate 150 to slide radially.

[0064] In this embodiment, the drive mechanism 140 includes a drive disk 141 and an operating unit 142. The operating unit 142 is located outside the lid body 100. Generally, the operating unit 142 may be located at the center of the top of the lid body 100, as shown in FIG. 4. This arrangement not only facilitates user operation but also improves the overall aesthetic appearance of the pressure cooker.

[0065] As one embodiment of the present application, as shown in FIG. 4, a first limiting flange 1123 corresponding to the driving disc 141 is further formed on the upper surface of the guide support member 112, and a second limiting flange 1412 engaging with the first limiting flange 1123 is formed on the bottom surface of the driving disc 141. The first limiting flange 1123 and the second limiting flange 1412 are annular, and both are fitted radially inside and outside the pot lid so as to realize restriction of the radial position of the driving disc 141.

[0066] In the embodiment of the present application, the annular first limiting flange 1123 and the annular second limiting flange 1412 are fitted together when installed, and the first limiting flange 1123 may be located outside the second limiting flange 1412 or inside the second limiting flange 1412, and when installed, the first limiting flange 1123 can restrict the driving disk 141 in the radial direction so that the driving disk 141 can rotate stably around the axis of the limiting flange when rotating.

[0067] 14, 15, and 16, in one embodiment of the present application, the driving disk 141 includes a driving body 1414 and a central driving part 1413 protruding from the upper surface of the driving body 1414, and the connecting part and the inserting part form a gap in the axial direction of the pot lid. The movable inserting plate 150 further includes a vertical plate 155 connecting the connecting part and the inserting part, and the connecting part is formed with the engaging part 157, the connecting part facing the central driving part 1413, the inserting part facing the driving body 1414, and the vertical plate 155 facing the outer surface of the central driving part 1413.

[0068] In this embodiment, the driving disk 141 and the movable insertion plate 150 are configured as a stepped structure that engages with each other. In this way, during design, the driving disk 141 and the movable insertion plate 150, which have a stepped structure, can improve their own structural strength while also replacing the function of the reinforcing support member 111 in the inner base 110, thereby reducing the overall number of parts of the pot lid.

[0069] As an embodiment of the present application, as shown in FIG. 13, the operating unit is rotatably provided on the outer lid of the lid body, an escape groove is formed on the upper surface of the outer lid, and the operating unit is connected to the drive disk via a connecting member that passes through the escape groove.

[0070] In one embodiment of the present application, as shown in FIG. 15, the movable insert plate 150 includes a flange 156 provided on the outer edge of the movable insert plate 150 and protruding from the bottom surface of the movable insert plate 150 along the axial direction of the pot lid.

[0071] The design of the flange 156 in this embodiment allows the thickness of the outer edge of the second inserting portion 154 to be increased, thereby further increasing the strength of the engagement.

[0072] In the related art, pressure cookers with a movable insert plate that can be extended inward and outward generally have through-holes in the sidewalls of the pot body. Because food and juices need to be tilted sideways during actual use, the length of the through-holes in the pot body along the circumferential direction of the pot body must not be too long (to prevent food from leaking through the through-hole assembly when the food is tilted), and thus the circumferential length of the movable insert plate must be correspondingly short. In this case, a thick insert plate is generally required to withstand pressure in order to ensure the strength of the engagement between the pot lid and the pot body. Furthermore, after the through-holes are provided in the pot body, food residues tend to get into the handle through the through-holes, making cleaning difficult and causing food residue to remain.

[0073] In view of this, in one embodiment of the present application, the multiple movable insertion plates 150 are arranged around the axis of the lid body 100, and the total length of the multiple insertion portions along the circumferential direction of the lid body 100 is 60% or more of the length of the outer surface of the movable insertion plate 150 along the circumferential direction of the lid body 100.

[0074] In practical applications, if space allows, the sum of the lengths of the plurality of movable insert plates 150 in the circumferential direction of the lid body 100 may be set to 75% or more of the circumferential length of the lid body.

[0075] As shown in FIGS. 3 and 13, when mutual movement between adjacent movable insert plates 150 does not interfere with each other, the circumferential length of each movable insert plate 150 is set to the maximum value.

[0076] As shown in Figures 2 and 9 to 12, the second aspect of the present application discloses a pressure cooker including a pot lid and a pot body 200, wherein the pot lid is the pot lid of the first aspect, and an annular inner boss 210 surrounding the axis of the pot body 200 is formed on the inner wall of the pot body 200, and when the pot lid closes the pot body 200, the drive mechanism 140 drives the movable insertion plate 150 so that it can be extended outward to the bottom side of the inner boss 210.

[0077] When the pot lid needs to be locked to the pot body 200 during use, as shown in Figures 11 and 12, in this case, the movable insertion plate 150 is extended from the lid body 100 and inserted below the inner boss 210, and a restricting effect is formed between the upper surface of the movable insertion plate 150 and the bottom surface of the inner boss 210. The high pressure within the pot body 200 lifts the pot lid upward, but due to the restriction between the movable insertion plate 150 and the inner boss 210, the pot lid cannot be detached from the pot body 200, thereby achieving a high-pressure locking effect between the pot body 200 and the pot lid.

[0078] As one embodiment of the present application, as shown in Figures 10 and 11, the inner wall of the pot body 200 is formed with a ring-shaped conical sealing portion 220 located at the bottom side of the inner boss 210, and the diameter of the upper end of the conical sealing portion 220 is larger than the diameter of the bottom end of the conical sealing portion 220. The pot lid includes an elastic sealing ring 130 fitted onto the lid body 100, and when the pot lid is closed on the pot body 200, the elastic sealing ring 130 abuts against the conical sealing portion 220 to form a seal with the pot body 200.

[0079] An annular conical sealing portion 220 is formed on the inner wall of the pot body 200, located at the bottom side of the inner boss 210, and the diameter of the upper end of the conical sealing portion 220 is larger than the diameter of the bottom end of the conical sealing portion 220. When the pot lid is closed on the pot body 200, the elastic sealing ring 130 abuts against the conical sealing portion 220 to form a seal with the pot body 200.

[0080] In this embodiment, a conical sealing portion 220 is provided on the inner wall of the pot body 200, so that when the pot lid is placed on the pot body 200, the conical sealing portion 220 and the elastic sealing ring 130 press against each other to form a sealing effect, and the conical structure can achieve a better sealing effect.

[0081] Naturally, in actual design, a handle 230 may be provided on the outer wall of the pot body 200 as shown in FIGS.

[0082] The above are only specific embodiments of the present application, and the scope of protection of the present application is not limited thereto. It is obvious to those skilled in the art that the present application includes, but is not limited to, the contents described in the drawings and the above specific embodiments. Any modifications that do not deviate from the functional and structural principles of the present application are included in the scope of the claims. [Explanation of symbols]
