Abstract
Description
Technical Field
[0001] This utility model relates to a push-type exhaust switch for use in a micro pressure cooker, belonging to the field of micro pressure cooker technology. Background Technology
[0002] The biggest difference between a pressure cooker and a regular pot lies in the pressure function; a pressure cooker has a certain pressure-generating capacity. When cooking food, a pressure cooker can instantly heat water to a boil, shortening cooking time and making it easier for ingredients to absorb flavor. In a regular pot, water takes a certain amount of time to boil, and food needs to be cooked and stewed for a longer time to absorb flavor.
[0003] When using a pressure cooker, the lid cannot be opened because the internal air is connected to the outside. Generally, a venting mechanism is required to release the air. However, the venting mechanism of existing pressure cookers is not designed reasonably. You have to keep pressing until the air is released before you can release your hand. This is not only time-consuming and laborious, but also results in poor venting and the risk of burning your hands. The effect of using it is not ideal. Summary of the Invention
[0004] To address the above problems, the technical problem to be solved by this utility model is to provide a push-type exhaust switch for use in a micro pressure cooker.

Detailed Implementation
[0022] like Figures 1-10 As shown, this specific embodiment adopts the following technical solution: It includes an exhaust main component 1, a connecting sleeve 2, a push rod 3, a sealing cover 4, a spring 5, a positioning sleeve 6, an exhaust switch 7, a push rod 8, a rotating guide post 9, a guide sleeve 10, and a rotating nut 11. An exhaust channel 101 is provided at the lower end of the exhaust main component 1, and an exhaust port 1011 is provided on the exhaust channel 101. A connecting sleeve 2 is provided in the central cavity of the exhaust main component 1. An exhaust channel opening 201 is provided on the side of the connecting sleeve 2 and communicates with the exhaust port 1011 on the exhaust channel 101. A central guide post through hole 202 is provided in the connecting sleeve 2 and communicates with the exhaust channel inlet 203 at the bottom of the central through hole of the connecting sleeve 2. A push rod 3 is provided in the central guide post through hole 202. A sealing cover 4 is fixed below the push rod 3. The sealing cover 4 is connected to the connecting sleeve 1. The sealing convex wall 204 on the inner wall of the connecting sleeve 2 cooperates to achieve the air-locking effect. A spring 5 is sleeved on the push rod 3, and a positioning sleeve 6 is set above the spring 5. The positioning sleeve 6 is snapped and fixed in the slot 301 of the push rod 3. The top of the push rod 3 has a cylindrical structure design. A push rod 8 is fixed below the center hole of the exhaust switch 7. A rotating guide post 9 is set in the cavity of the push rod 8. The top of the push rod 3 is set in the connecting arc groove at the bottom of the rotating guide post 9. The push rod 8 and the rotating guide post 9 are set in the guide sleeve 10. The guide sleeve 10 is fixed in the connecting cavity of the connecting sleeve 2 and is fixed in the groove 205 on the inner side of the connecting cavity of the connecting sleeve 2 by the convex ring 1001 on the outside of the guide sleeve 10. An external thread 206 is set at the bottom of the connecting sleeve 2 and is screwed and fixed with the internal thread 1101 in the rotating nut 11.
[0023] The top of the connecting sleeve 2 is integrally provided with a protrusion 207, which is snapped and fixed in the slot on the side wall of the central cavity of the exhaust main component 1. The slot and the protrusion 207 are designed with an irregular shape to prevent the connecting sleeve 2 from rotating.
[0024] The bottom side of the push rod 8 is provided with several positioning protrusions 801, and the bottom edge of the positioning protrusions 801 is provided with a toggle tooth ring 802. The lower end of the rotating guide post 9 is provided with a rotating protrusion helical tooth 901. The helical tooth direction of the rotating protrusion helical tooth 901 is located on one side of the exhaust switch 7. The rotating protrusion helical tooth 901 and the toggle tooth ring 802 cooperate with each other to convert linear motion into rotational motion.
[0025] A locking slide rail 1002 is provided inside the guide sleeve 10. The positioning protrusion tooth 801 on the push rod 8 can slide up and down on the locking slide rail 1002. The positioning protrusion tooth 801 engages when sliding in and out. An opening ramp tooth ring 1003 is provided below the locking slide rail 1002. The protrusion of the rotating protrusion tooth 901 slides up and down on the inner edge of the opening ramp tooth ring 1003. The principle of opening and locking the sealing cover is completed through the three components.
[0026] This specific embodiment effectively achieves the principle of opening and locking by using the rotating convex helical teeth 901 and locking slide rail 1002 and opening ramp gear ring 1003. By pressing the exhaust switch 7, the actuating gear ring 802 on the push rod 8 pushes the rotating convex helical teeth 901 to move downward. The cooperation between the actuating gear ring 802 and the rotating convex helical teeth 901 completes a micro-rotation to make the rotating guide post 9 rotate. The upward force of the spring 5 pushes the rotating convex helical teeth 901 of the rotating guide post 9 to reach the locking slide rail 1002 or the opening ramp gear ring 1003 to lock. The locking slide rail 1002, which is set in the guide sleeve 10 by several positioning convex teeth 801 on the push rod 8, moves up and down without rotating.
[0027] The driving principle of this specific embodiment is as follows: Pressing down on the exhaust switch 7 causes the actuating gear ring 802 on the push rod 8 to push the rotating convex helical gear 901 to slide out of the locking slide rail 1002 and rotate. The rotating convex helical gear 901 then slides into the edge of the opening ramp gear ring 1003 below the locking slide rail 1002, and a click sound is heard upon contact. When the exhaust switch 7 is released, the spring 5 pushes the rotating convex helical gear 901 to contact the edge of the opening ramp gear ring 1003, and the rotation amplitude increases. When it reaches the opening ramp gear ring 1003, a second click sound will be heard. Simultaneously, the push rod 3 moves downward, causing the sealing cover 4 to move downward. At this time, the exhaust channel inlet 203 is in the open state and the locking is released, waiting for the gas to be discharged completely.
[0028] In this specific embodiment, pressing down on the exhaust switch 7 causes the actuating gear ring 802 on the push rod 8 to push the rotating convex helical gear 901 to slide out of the ramp gear ring 1003 and rotate to reach the locking slide rail 1002. Releasing the finger pressure causes the spring 5 to push the rotating convex helical gear 901 into the locking slide rail 1002, sealing and locking with a click.
[0029] This specific implementation method has a reasonable structural design, beautiful appearance, novel and unique shape, simple operation, and convenient use. The exhaust port is opened by pressing the exhaust switch, and the user can release the switch without pressing it continuously. After the exhaust is completed, press the exhaust switch to close the exhaust port. It not only saves time and effort, but also ensures smooth exhaust and avoids the risk of burning hands. The effect of use is very ideal.
