[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0016] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail. This application discloses a microwave-heated bowl lid structure for takeout food with a pressure-reducing valve. (Refer to...) Figures 1-7 A microwave-heated bowl lid structure for takeout with a pressure-reducing valve includes a takeout lid 1. A toggle bar 4 is fixedly connected to the top of the takeout lid 1. A sealing plug 6 is fixedly connected to one side of the toggle bar 4. A fixing ring 14 is fixedly connected to the surface of the sealing plug 6. A fixing cylinder 7 is fixedly connected to the top of the takeout lid 1. A pressure-reducing mechanism 8 is provided inside the fixing cylinder 7. The pressure-reducing mechanism 8 includes a venting groove 802, which is formed on the inner wall of the fixing cylinder 7. A blocking plate 801 is slidably connected to the inner wall of the venting groove 802. The bottom of the blocking plate 801... The microwave oven is fixedly connected to a limiting rod 803, and the bottom of the limiting rod 803 is fixedly connected to a limiting block 804. When the user needs to heat the takeout food, he / she needs to remove the sealing plug 6 first, and then put the takeout food into the microwave oven to heat it. After the internal temperature of the takeout bowl rises, the air pressure increases. The air pressure will push the plug plate 801 upward, so that the inside of the microwave oven is connected to the inside of the takeout lid 1 through the ventilation groove 802. This can prevent the hot soup from spraying out and causing burns when the user opens the microwave oven while heating the takeout food.
[0017] Reference Figure 1 A pull block 5 is fixedly connected to the bottom of the sealing plug 6, and a friction pad 2 is fixedly connected to the surface of the takeaway lid 1. The pull block 5 installed on the sealing plug 6 makes it easy for users to remove the sealing plug 6 and then heat the takeaway food. The friction pad 2 installed on the surface of the takeaway lid 1 can prevent the takeaway lid from slipping when the user puts the takeaway lid 1 on the takeaway bowl. Reference Figure 1 A label plate 11 is fixedly connected to the top of the takeaway cover 1, and a support rib plate 13 is fixedly connected to the inner wall of the takeaway cover 1. The label plate 11 installed on the takeaway cover 1 can remind the user of the position of the heat insulation sheet 9 and the clip 10 so that the user can remove the takeaway cover 1. The support rib plate 13 installed inside the takeaway cover 1 fixes the takeaway cover 1 in the takeaway bowl. Reference Figure 1A clip 10 is fixedly connected to the surface of the takeaway lid 1, and a heat insulation sheet 9 is fixedly connected to the surface of the clip 10. The clip 10 installed on the surface of the takeaway lid 1 can increase the connection strength between the takeaway lid 1 and the takeaway bowl and prevent the takeaway food from leaking out. The heat insulation sheet 9 installed on the surface of the takeaway lid 1 makes it easy for users to remove the takeaway lid 1 and avoids causing burns to users. Reference Figure 1 The top of the takeout lid 1 is fixedly connected with a clip 3. There are two clips 3, which can be used to fix chopsticks and spoons so that users can take them. Reference Figure 4 An installation ring 15 is fixedly connected to the inner wall of the takeaway lid 1, and a sealing ring 16 is fixedly connected to the inner wall of the installation ring 15. The installation ring 15 installed in the sealing ring 16 can increase the sealing between the takeaway lid 1 and the takeaway bowl, and prevent takeaway food from flowing out from the gap between the takeaway lid 1 and the takeaway bowl. Reference Figure 2 The inner wall of the takeaway lid 1 is fixedly connected with two retaining rings 12, which can enhance the overall strength of the takeaway lid 1.
[0018] Working principle: Before heating the takeout food, the user first pinches the pull block 5 to remove the sealing plug 6, and then puts the takeout food into the microwave oven for heating. The microwave oven heats the food by causing the water molecules in the food to vibrate. After the temperature inside the takeout bowl rises, the air pressure increases, which pushes the sealing plate 801 upward, so that the inside of the microwave oven is connected to the inside of the takeout lid 1 through the ventilation groove 802. While heating the takeout food, the user can avoid the hot soup spraying out when opening the microwave oven, which could cause burns. After heating is finished, the user can pry open the latch 10 and pinch the heat insulation sheet 9 to remove the takeout lid 1. When it is necessary to keep the food warm, the sealing plug 6 on the takeout lid 1 can be sealed to the fixing cylinder 7 to reduce the loss of heat from the food.
[0019] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
