[0032] The present invention provides a pot lid structure for use in a rice cooker. The specific structure and function of the pot lid structure provided in the present invention will be further described below with reference to the text and accompanying drawings.

[0033] Reference Figures 1 to 4 According to the first aspect of the present invention, the pot lid structure includes an outer lid 100 and an inner lid 200. The outer lid 100 is made of plastic and has good heat insulation and high temperature resistance. A receiving cavity 110 and a insertion cavity 120 are provided on the lower side of the outer lid 100, with the receiving cavity 110 located in front of the insertion cavity 120. A first snap-fit ​​member 130 is provided on the rear wall of the insertion cavity 120. The first snap-fit ​​member 130 is a horizontally extending forward block-shaped protrusion that forms an insertion groove with the upper wall of the insertion cavity 120. A second snap-fit ​​member 140 is provided on the front wall of the receiving cavity 110, which is an upwardly protruding snap-fit ​​structure. The inner lid 200 consists of a fixing ring 210 and a glass cover 220. The fixing ring 210 is made of high-temperature resistant plastic, while the glass cover 220 is made of transparent glass, possessing good heat resistance and impact resistance. The glass cover 220 is fixed to the fixing ring 210. The fixing ring 210 has a buckle 230 on its front side and a plug-in block 240 on its rear side. The shape of the plug-in block 240 matches the plug-in groove. During assembly, the inner cover 200 is placed into the receiving cavity 110 of the outer cover 100, and the plug-in block 240 is inserted into the plug-in groove, so that the upper wall of the first buckle 130 abuts against the lower wall of the plug-in block 240. Then, the buckle 230 is engaged with the second buckle 140, thereby achieving a stable connection between the inner cover 200 and the outer cover 100. During the operation of the rice cooker, the water vapor inside the pot will condense into water droplets when it encounters the relatively cool glass cover 220. Due to the surface characteristics of the glass cover 220, the water droplets can slide off the glass cover 220 smoothly and will not accumulate in large quantities on the inner cover 200. When the user opens the rice cooker lid, water droplets will not fall into the water collection tank in large quantities, effectively solving the problem of water droplets falling from the inner lid of existing rice cookers, and improving the convenience and user experience of using the rice cooker.

[0034] According to the lid structure provided in the first aspect of this utility model, by using a glass lid 220 as the main part of the inner lid 200, the surface characteristics of the traditional metal inner lid 200 are changed. The smooth surface of the glass material makes it difficult for water droplets to adhere, allowing condensed water droplets to fall more easily from the inner lid 200. When the user opens the rice cooker lid, water droplets will not fall into the water collection tank in large quantities, effectively preventing a rapid increase in water volume and the accumulation of impurities and dirt in the water collection tank. This reduces the frequency of disassembly and cleaning of the water collection tank, greatly improving the convenience and user experience of using the rice cooker. Secondly, the engagement of the snap fastener 230 with the second snap fastener 140, and the cooperation of the insertion block 240 with the insertion slot, ensures the reliable fixation of the inner lid 200 within the outer lid 100 receiving cavity 110, guaranteeing the stability and safety of the lid during use. This structure is not only easy to install and disassemble, but also adaptable to rice cookers of different sizes and shapes, possessing wide applicability.

[0035] Reference Figure 2 and Figure 4 According to the pot lid structure provided in the first aspect embodiment of this utility model, a retaining block 250 is connected to each of the left and right sides of the fixing ring 210. These two retaining blocks 250 are symmetrically arranged, with a roughly circular block shape, and are made of the same high-temperature resistant plastic material as the fixing ring 210. One end of each retaining block 250 is fixedly connected to the fixing ring 210, while the other end is a free end. When the inner lid 200 is installed in the receiving cavity 110 of the outer lid 100, the free ends of the two retaining blocks 250 abut against the left and right side walls of the receiving cavity 110, respectively. This makes the inner lid 200 more stable within the receiving cavity 110, preventing the inner lid 200 from shifting left or right due to vibration or shaking during use.

[0036] Reference Figures 1 to 3 According to the pot lid structure provided in the first aspect embodiment of this utility model, two first snap-fit ​​members 130 are provided on the rear side wall of the insertion cavity 120. The two first snap-fit ​​members 130 are symmetrically arranged in the horizontal direction, both extending forward in the horizontal direction, and forming two insertion grooves with the upper wall of the fixing ring 210. The upper side wall of each first snap-fit ​​member 130 is a horizontal plane. When the insertion block 240 of the inner cover 200 is inserted into the insertion groove, the upper side walls of the two first snap-fit ​​members 130 abut against the lower side wall of the insertion block 240. This makes the connection between the inner cover 200 and the outer cover 100 more stable, and the position of the insertion block 240 in the insertion groove more accurate, avoiding problems such as the inner cover 200 shaking or falling off due to the loose fit between the insertion block 240 and the insertion groove. Meanwhile, the two first snap-fit ​​connectors 130 also improve the reliability of the connection. Even if one of the first snap-fit ​​connectors 130 is damaged or deformed, the other first snap-fit ​​connector 130 can still maintain effective contact with the plug block 240, ensuring the stable installation of the inner cover 200 inside the outer cover 100.

[0037] Reference Figure 2 and Figure 4 According to the pot lid structure provided in the first aspect embodiment of this utility model, the upper wall of the plug-in block 240 is provided with two limiting blocks 260. These two limiting blocks 260 are located at the left and right ends of the plug-in block 240, integrally formed with the plug-in block 240, and are also made of high-temperature resistant plastic. The limiting blocks 260 are rectangular blocks, and their height is slightly lower than the height of the plug-in block 240. When the plug-in block 240 is inserted into the plug-in cavity 120 and the upper side wall of the first snap-fit ​​member 130 abuts against the lower side wall of the plug-in block 240, the two limiting blocks 260 abut against the side walls of the two first snap-fit ​​members 130 respectively. This further enhances the connection stability between the inner cover 200 and the outer cover 100. The abutment between the limiting block 260 and the side wall of the first snap-fit ​​member 130 restricts the lateral movement of the insertion block 240 within the insertion cavity 120, preventing the insertion block 240 from disengaging from the first snap-fit ​​member 130 due to external forces or vibrations during use, thereby ensuring the secure installation of the inner cover 200 within the outer cover 100. Simultaneously, the limiting block 260 also helps improve the fitting accuracy between the insertion block 240 and the insertion cavity 120, making the assembly of the inner cover 200 and the outer cover 100 smoother, and improving the assembly efficiency and overall performance of the lid structure.

[0038] Reference Figures 1 to 3 According to the pot lid structure provided in the first aspect embodiment of this utility model, the lower side of the outer lid 100 is provided with a relief cavity 150 communicating with the receiving cavity 110. The relief cavity 150 is rectangular in shape, and the second snap-fit ​​member 140 is disposed in the relief cavity 150, specifically located in the middle of the relief cavity 150. The second snap-fit ​​member 140 is a downwardly extending snap-fit ​​structure, and its shape matches the snap-fit ​​member 230 of the inner lid 200. When the inner lid 200 is installed into the receiving cavity 110 of the outer lid 100, the snap-fit ​​member 230 on the front side of the fixing ring 210 can smoothly snap into the second snap-fit ​​member 140 in the relief cavity 150, realizing a stable connection between the inner lid 200 and the outer lid 100. The design of the relief cavity 150 not only provides installation space for the second snap-fit ​​member 140, but also allows the inner lid 200 to enter the receiving cavity 110 more smoothly during installation, reducing installation resistance and improving installation efficiency. Meanwhile, when it is necessary to remove the inner cover 200, the user can insert their fingers into the relief cavity 150 to pry open the second latching member 140, thereby separating the second latching member 140 from the latching member 230.

[0039] Reference Figure 2 and Figure 3According to the pot lid structure provided in the first aspect embodiment of this utility model, the rear wall surface of the second snap-fit ​​member 140 is provided with a snap-fit ​​groove 141, which is a horizontally arranged groove whose shape matches the front end of the snap-fit ​​member 230. When the inner lid 200 is installed into the receiving cavity 110 of the outer lid 100, the front end of the snap-fit ​​member 230 can be smoothly snapped into the snap-fit ​​groove 141 on the rear wall surface of the second snap-fit ​​member 140. This snap-fit ​​structure design makes the connection between the inner lid 200 and the outer lid 100 tighter and more stable. The cooperation between the elastic hook-shaped front end of the snap-fit ​​member 230 and the snap-fit ​​groove 141 can effectively prevent the inner lid 200 from loosening or falling off due to vibration or external force during use. At the same time, this snap-fit ​​method also facilitates the installation and removal of the inner lid 200. The user only needs to apply appropriate force to disengage the front end of the snap-fit ​​member 230 from the snap-fit ​​groove 141 to easily remove the inner lid 200 from the outer lid 100 for cleaning or replacement.

[0040] Reference Figure 2 and Figure 4 According to the pot lid structure provided in the first aspect embodiment of this utility model, the fixing ring 210 is provided with a mounting groove 211, which is annular in shape and located on the inner sidewall of the fixing ring 210. The depth and width of the mounting groove 211 are adapted to the outer edge dimensions of the glass cover 220, ensuring that the glass cover 220 can be securely installed in the fixing ring 210. The outer edge shape of the glass cover 220 matches the shape of the mounting groove 211, ensuring a tight fit. During assembly, the outer edge of the glass cover 220 is aligned with the mounting groove 211 of the fixing ring 210, and gently pressed to embed the outer edge of the glass cover 220 into the mounting groove 211, thereby achieving a fixed connection between the glass cover 220 and the fixing ring 210. This installation method is not only simple to operate but also provides a firm connection, effectively preventing the glass cover 220 from shifting or falling off due to vibration or impact during use. Meanwhile, the design of the mounting groove 211 also provides a certain degree of protection for the glass cover 220, preventing the edge of the glass cover 220 from being directly exposed to the outside world and thus being damaged, extending the service life of the glass cover 220, and further improving the reliability and safety of the pot lid structure.

[0041] Reference Figure 4 According to the pot lid structure provided in the first aspect embodiment of this utility model, both the fastener 230 and the fixing ring 210 are integrally molded from high-temperature resistant plastic material through injection molding. This makes the connection between the fastener 230 and the fixing ring 210 more secure, eliminating the problem of loosening or falling off due to weak connection, thus improving the stability and reliability of the pot lid structure. Furthermore, the integrally molded fastener 230 and fixing ring 210 are easier to guarantee in terms of dimensional accuracy and fitting precision, which helps to improve the assembly precision between the inner lid 200 and the outer lid 100, further enhancing the overall performance and service life of the pot lid.

[0042] Reference Figure 4 According to the pot lid structure provided in the first aspect embodiment of this utility model, the plug-in block 240 and the fixing ring 210 are integrally formed, which greatly improves the connection strength between the plug-in block 240 and the fixing ring 210. Since there are no connection gaps, the integrally formed structure can effectively avoid loosening of the connection due to long-term use or heat deformation, ensuring the stability of the inner lid 200 during use.
