[0020] 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 protection scope of the present utility model.
[0021] Please see Figure 1-5 As shown, a pressure cooking appliance with a sliding lid includes a pressure cooker body 1, a pressure cooker lid 2, and a handle 3 fixed to one side of the pressure cooker body 1. A heat insulation box 4 is fixedly connected to the right side of the pressure cooker body 1. A heat insulation cover 5 is provided on the top of the heat insulation box 4. Fixing plates 6 are fixed on both sides of the bottom of the heat insulation cover 5. T-shaped grooves 7 are provided on the opposite sides of the two fixing plates 6. A T-shaped slider 8 is slidably connected inside the T-shaped groove 7. A spring-loaded body 9 is fixed on the side of the T-shaped slider 8 away from the T-shaped groove 7. A square locking block 10 is provided at the other end of the spring-loaded body 9. A winding rod 11 is locked between the two square locking blocks 10. A heat insulation cloth 12 is wrapped around the surface of the winding rod 11. The other end of the heat insulation cloth 12 passes through the heat insulation cover 5 and is located above the heat insulation cover 5.
[0022] A connecting plate 13 is fixed to the top of the heat insulation cloth 12. Hooks 14 are fixed to both sides of the top of the connecting plate 13. Hanging rings 15 are rotatably connected to both the front and rear sides of the handle 3. The hooks 14 and hanging rings 15 are used together. When the heat insulation cloth 12 is pulled out, the hooks 14 can be hung inside the hanging rings 15 to fix the heat insulation cloth 12 after it is pulled up.
[0023] The surface of the heat insulation box 4 has a fastening bolt 17, and the other end of the fastening bolt 17 is connected to the internal thread of the front fixing plate 6. When the heat insulation cover 5 and the fixing plate 6 are inserted into the heat insulation box 4, the fastening bolt 17 can be rotated to fix the heat insulation box 4, the heat insulation cover 5 and the fixing plate 6.
[0024] The top of the connecting plate 13 is rotatably connected to the limiting block 16, so that when the heat insulation cloth 12 is rolled up, the limiting block 16 can contact the heat insulation cover 5, thereby limiting the heat insulation cloth 12.
[0025] The pressure cooker lid 2 is fixed with a protective cover 18 on top, and the protective cover 18 is located outside the pressure relief valve. By setting the protective cover 18, the steam can be blocked when the pressure relief valve is releasing steam, so as to prevent injury to the user.
[0026] The inner wall of the T-shaped slide groove 7 is provided with an anti-slip pad, and the anti-slip pad is in contact with the surface of the T-shaped slider 8. In this way, the anti-slip pad can increase the friction between the T-shaped slider 8 and the T-shaped slide groove 7, and prevent random sliding.
[0027] Working principle: Before cooking food in the pressure cooker, the hook 14 can be pulled to move it upward. During the movement, the connecting plate 13 and the heat insulation cloth 12 will move together, thereby covering the outer surface of the pressure cooker body 1. Then the hook 14 is hung on the hanging ring 15 to fix the pulled-up heat insulation cloth 12. When the cooking is completed, the user holds the handle 3, and at this time the hand will not come into contact with the pressure cooker body 1.
[0028] When the heat insulation cloth 12 needs to be replaced due to stains on its surface after prolonged use, the fastening bolt 17 can be rotated to remove the limiting position between the heat insulation box 4 and the front fixing plate 6. Then, the heat insulation cover 5 can be pulled, and the fixing plate 6 can be pulled away from the inside of the heat insulation box 4. Next, the hook 14 can be rotated so that the bent parts of the two hooks 14 turn in the same direction. At this time, the limiting block 16 can be rotated in the same direction as the hook 14. Then, the winding rod 11 can be pulled downwards so that the T-shaped sliders 8 on both sides can be disengaged from the inside of the T-shaped slide groove 7. The connecting plate 13, hooks 14 and limiting block 16 will slide down from the top of the heat insulation cover 5 together. Finally, the mainspring bodies 9 on both sides can be separated from the winding rod 11, so that the heat insulation cloth 12 can be disassembled and replaced.
