Abstract
Description
Technical Field
[0001] This utility model relates to the field of pressure cookers, and in particular to a one-button venting structure for a press-type lid. Background Technology
[0002] Pressure cookers are favored by consumers because they cook food under high internal pressure. However, most pressure cookers require manual opening of the exhaust valve, which can easily burn hands when releasing air. Utility Model Content
[0003] To solve the above problems, this technical solution provides a one-button venting structure for a press-type pot lid.
[0004] To achieve the above objectives, the technical solution is as follows:
[0005] The one-button venting structure of the press-type pot lid includes a button set on the pot lid, the button having a shaft passing through the pot lid, the shaft being fitted with a spring, and one end of the shaft extending into the interior;
[0006] It also includes a lever hinged inside the pot lid, one end of which is located below the shaft, and the other end is used to lift the exhaust valve.
[0007] In some embodiments, the lever has a fulcrum through which a pin passes, and a first baffle and a second baffle are provided inside the pot lid to limit the pin.
[0008] In some embodiments, the fulcrum is located near one end of the lever.
[0009] In some embodiments, the fulcrum is a U-shaped groove through which the pin passes.
[0010] In some embodiments, one end of the lever is inclined excessively, with a first protrusion at the inclined point and a second protrusion at the other end, wherein the area of the first protrusion is smaller than the area of the second protrusion.
[0011] In some embodiments, the button is provided with a latch, which engages with a slot located inside the pot lid.
[0012] The beneficial effects of this application are:
[0013] This application allows one end of a lever to move downwards by pressing a button, thereby lifting the exhaust valve at the other end of the lever to release air, thus preventing direct contact between the user's hand and the exhaust valve and avoiding burns. Attached Figure Description
[0014] To more clearly illustrate the technical solutions in the embodiments of this utility model, the accompanying drawings used in the description of the embodiments will be briefly introduced below.
[0015] Figure 1 This is a cross-sectional schematic diagram of an embodiment of the present utility model. Figure 1 ;
[0016] Figure 2 This is a cross-sectional schematic diagram of an embodiment of the present utility model. Figure 2 . Detailed Implementation
[0017] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0018] Please refer to Figure 1-2 As shown, the one-button venting structure of the press-type pot lid is characterized by including a button 1 set on the pot lid, the button 1 having a shaft 2 passing through the pot lid, the shaft 2 being fitted with a spring 3, and one end of the shaft 2 extending into the interior.
[0019] It also includes a lever 4 hinged inside the pot lid, one end of which is located below the shaft 2, and the other end is used to lift the exhaust valve 5.
[0020] This application allows the lever to move downwards by pressing a button, which in turn lifts the exhaust valve at the other end of the lever, thus venting the air and preventing direct contact between the user's hand and the exhaust valve, thereby avoiding burns. Then, the spring drives the button to reset.
[0021] In this embodiment, the lever 4 is provided with a fulcrum 6, through which a pin 7 passes. Inside the pot lid, there is a first baffle 8 and a second baffle 9 for limiting the pin 7. The pin is L-shaped and is fixed after passing through the second baffle, thereby supporting the lever. In addition, the second baffle limits the lever to ensure its horizontal position and prevent it from moving back and forth.
[0022] In this embodiment, the fulcrum 6 is located near one end of the lever 4, and the fulcrum of the lever is biased to one side. The distances from the two ends of the lever to the fulcrum are different, and the side of the lever with a longer distance from the fulcrum has a greater weight than the side with a shorter distance. The side of the lever with a shorter distance from the fulcrum is connected to the button, while the side with a longer distance is placed under the exhaust cap. When there is no external force, the side of the lever with a longer distance from the fulcrum will return to its original position under its own weight.
[0023] In this embodiment, the fulcrum 6 is a U-shaped groove through which the pin 7 passes. During installation, the U-shaped groove is simply placed on the pin to achieve the flipping.
[0024] In this embodiment, one end of the lever 4 is tilted excessively, with a first protrusion 10 at the tilted end and a second protrusion 11 at the other end. The area of the first protrusion 10 is smaller than the area of the second protrusion 11. The excessive tilt is to make it easier to contact the shaft and achieve flipping. In addition, the two ends have different gravity due to the different areas of the protrusions. Therefore, after the button is reset, the lever resets itself due to gravity.
[0025] In this embodiment, the button 1 is provided with a buckle 12, which cooperates with the slot 13 located in the pot lid. This not only makes it convenient to install the button, but also allows the buckle to slide up and down in the slot.
[0026] The above description is only a preferred embodiment of this application and is not intended to limit the scope of implementation of this application. Any other embodiments whose principles and basic structures are the same as or similar to those of this application are within the protection scope of this application.
