[0029] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following embodiments are used to illustrate the technical solution of the present invention, but are not intended to limit the scope of protection of the present invention.

[0030] Example:

[0031] like Figures 1 to 4 As shown, the present invention provides a rice cooker air valve, comprising an air valve housing 101 with an air valve cover plate 102 disposed above the air valve housing 101. The air valve cover plate 102 covers the open side of the air valve housing 101, and the two together form an exhaust chamber, a key channel for gas discharge. An exhaust slot 103 is formed in the air valve cover plate 102, which allows the exhaust chamber to communicate with the outside world. When steam or other gases are generated inside the rice cooker, these gases can be smoothly discharged to the outside world through the exhaust slot 103, thereby ensuring stable and safe pressure inside the rice cooker. The exhaust slot 103 is a strip-shaped exhaust slot with a specific extension direction, which is perpendicular to the extension direction of the first guide rib 106, facilitating gas discharge and flow guidance. When gas is discharged through the exhaust slot 103, the vertical orientation allows for smoother gas discharge and reduces airflow resistance. It also facilitates cooperation with the first guide rib 106 to better guide the water flow or other liquid after steam liquefaction. A valve member 104 is further provided in the exhaust chamber.

[0032] The air valve housing 101 is provided with a ventilation groove 105, and one end of the valve element 104 is arranged in the ventilation groove 105. The valve element 104 can move according to the pressure in the rice cooker to adjust the discharge speed and flow of the gas, and ensure the stability and safety of the rice cooker during operation. The top surface of the air valve cover plate 102 is provided with a plurality of first guide ribs 106, and the top surface is an inclined arc surface. This arc surface not only conforms to the principle of ergonomics, making the air valve more beautiful in appearance, but also has important functions in actual use. The arc surface can reduce the risk of scalding when the user contacts the air valve cover plate 102, because the contact area is smaller and the heat transfer is relatively slow compared to a flat surface. At the same time, the strip-shaped exhaust groove is arranged outside the top end of the arc surface, which can avoid the direct impact of the discharged gas on the top end of the arc surface during the exhaust process, reduce the impact and erosion of the gas on the arc surface, and prolong the service life of the air valve cover plate 102. Moreover, the positional relationship between the arc surface and the strip-shaped exhaust groove is also conducive to the better diffusion and flow of the gas after discharge, and cooperates with the first guide ribs 106 to achieve the guide effect on the liquid.

[0033] In addition, one side of the air valve housing 101 is provided with a mounting clamping groove 107, and the mounting block 108 can be clamped in the mounting clamping groove 107. A spring is also arranged in the mounting clamping groove 107, and the two ends of the spring are connected with the mounting block 108 and the air valve housing 101 respectively. One side of the mounting block 108 is provided with a first buckle 109, and the air valve cover plate 102 is provided with a mounting plate 110. The mounting plate 110 is provided with a mounting groove 111, and the first buckle 109 can be clamped in the mounting groove 111, thereby realizing the stable connection between the air valve cover plate 102 and the air valve housing 101. The bottom of the valve element 104 is provided with two groups of second buckles 112, which can be clamped in the air valve housing 101 through the ventilation groove 105. In order to ensure the sealing performance of the air valve, a sealing ring 113 is arranged between the air valve housing 101 and the air valve cover plate 102, and the sealing ring 113 is detachably connected with the air valve cover plate 102, which is convenient for replacement and maintenance when needed.

[0034] As shown in Figures 5 to 7 A rice cooker top cover, including a top cover body 21, also makes the structure of the whole rice cooker top cover more reasonable and the space utilization more efficient. The top cover body 21 is provided with an assembly through groove 22, and the air valve housing 101 and the air valve cover plate 102 are located in the assembly through groove 22, so that the rice cooker air valve is located in the assembly through groove 22 and at the highest point of the arch. Since it is located at the highest point, the air valve can better play its role in the exhaust process, ensuring that the steam and other gases generated inside the rice cooker can be smoothly discharged, maintaining the pressure balance inside the rice cooker.

[0035] A plurality of second flow guide ribs 23 are arranged on the top surface of the top cover body 21. When steam is condensed into water or other liquid appears during the operation of the rice cooker, the flow guide ribs can guide the liquid to a specific position, avoiding the liquid from flowing randomly on the top cover, thereby keeping the top cover clean and dry.

[0036] The top surface of the top cover body 21 is further divided into a valve surface and a button surface. The assembly through groove 22 and the second flow guide rib 23 are arranged on the valve surface, making the valve area more clear and prominent. A partition strip 24 is arranged between the valve surface and the button surface. The top surface of the partition strip 24 is higher than the valve surface and the button surface, and it plays a clear distinguishing role. In actual use, this clear distinguishing structure can effectively avoid accidental touch of the valve being vented when operating the button during cooking, thereby reducing the risk of accidental scalding and improving the safety of the rice cooker.

[0037] As shown in Figures 8 to 10 A rice cooker includes a rice cooker cover 31, and the rice cooker cover 31 is provided with the above-mentioned rice cooker top cover. The top cover body 21 is detachably connected with the rice cooker cover 31, which brings convenience for daily use and maintenance. When cleaning the rice cooker or repairing the internal components, the rice cooker top cover can be easily separated from the rice cooker cover 31, which is convenient for operation.

[0038] A containing box 32 is arranged above the rice cooker cover 31, and a connecting groove 33 is formed on the rice cooker cover 31. The containing box 32 is clamped in the connecting groove 33. The stability of the containing box 32 on the rice cooker cover 31 is ensured, and the containing box 32 will not shake or shift during the use of the rice cooker. The rice cooker valve is clamped in the containing box 32, which makes the installation of the rice cooker valve more firm, and also facilitates the disassembly and replacement of the valve.

[0039] The rice cooker cover 31 is provided with control buttons 34, which are important interfaces for users to operate the rice cooker. The top cover body 21 is provided with button grooves 25 corresponding to the control buttons 34. The control buttons 34 can be clamped in the button grooves 25 and protrude above the top cover body 21.

[0040] As shown in Figure 4 , Figure 7 , Figure 10As shown, the bottom of the top cover body 21 is provided with a plurality of assembly columns 26, and the rice cooker cover 31 is provided with assembly holes 35 corresponding to the assembly columns 26, and the assembly columns 26 can be arranged in the assembly holes 35, thereby realizing the preliminary connection between the rice cooker top cover and the rice cooker cover 31. In order to further strengthen the connection stability between the two, assembly screw holes are arranged on the assembly columns 26 and the rice cooker cover 31. Assembly screws can be arranged in these assembly screw holes, and by tightening the assembly screws, the connection between the rice cooker top cover and the rice cooker cover 31 is more firm and reliable.

[0041] The bottom of the holding box 32 is provided with a first connecting sleeve 36, and the bottom of the gas valve shell 101 is provided with a second connecting sleeve 1104, and the second connecting sleeve 1104 can be arranged in the first connecting sleeve 36, thereby providing an effective way for the connection between the rice cooker gas valve and the holding box 32. Meanwhile, connecting clamping blocks 115 are arranged on both sides of the second connecting sleeve 1104. The first connecting sleeve 36 is provided with a connecting clamping ring 37. The two groups of connecting clamping blocks 115 can be clamped on the connecting clamping ring 37, and by means of this clamping, the stability of the rice cooker gas valve in the holding box 32 is further ensured, and the safety and reliability of the rice cooker during use are ensured.

[0042] The specific use and effect of the embodiment are as follows:

[0043] In use, the control button 34 on the rice cooker cover 31 is operated. The control button 34 passes through the button slot 25 arranged on the top cover body 21 and protrudes above the top cover body 21, thereby facilitating the user to operate. During the operation of the rice cooker, the steam and other gases generated in the rice cooker enter the exhaust cavity through the air passage 105 in the gas valve shell 101, and then are discharged to the outside through the exhaust slot 103 on the gas valve cover plate 102, thereby ensuring that the internal pressure of the rice cooker is within a safe and appropriate range. If water flow formed by steam liquefaction or other liquids appear, the plurality of first flow guide ribs 106 on the top surface arc surface of the gas valve shell 101 can guide these liquids to the same position for centralized treatment. Meanwhile, the plurality of second flow guide ribs 23 on the gas valve surface of the top cover body 21 can also guide the liquids to a specific position, thereby avoiding the liquids from flowing randomly on the top cover. The partition strip 24 between the gas valve surface and the button surface can effectively avoid the accidental touch of the gas valve being exhausted when the button is operated, thereby reducing the risk of accidental scalding.

[0044] The basic principle and main features of the utility model and the advantages of the utility model are shown and described above, and for those skilled in the art, it is obvious that the utility model is not limited to the details of the above-mentioned exemplary embodiments.
