[0001] This utility model relates to a stand-up micro pressure cooker switch handle, belonging to the technical field of micro pressure cooker accessories. Background technology:

[0002] Pressure cookers, as common kitchen utensils, are widely used in home cooking due to their gentle cooking environment and efficient heating. Currently, most pressure cooker handles on the market are designed to not stand upright, requiring the lid to be placed directly on the stovetop after opening. However, the stovetop surface often retains water stains and grease, easily contaminating the lid and affecting hygiene. Furthermore, existing pressure cookers mostly rely on knobs for opening and locking, which is not only cumbersome but also fails to achieve simultaneous venting when opening the lid, posing inconvenience and safety hazards. Utility Model Content:

[0003] To address the aforementioned problems, the present invention aims to provide a stand-up pressure cooker handle. By optimizing the handle's structural design, the lid can be placed upright. Simultaneously, a lever-type operation is used to open and lock the lid, while also coordinating with the exhaust mechanism, thereby improving the hygiene, convenience, and safety of the pressure cooker.

[0004] This utility model discloses a stand-up micro pressure cooker switch handle, which includes a straight switch body, a positioning pin, a stand-up switch handle, a locking device, a bottom cover, and an exhaust linkage mechanism. The upper part of the straight switch body is rotatably connected to the stand-up switch handle through the positioning pin. A cavity is provided at the bottom of the straight switch body, and a locking device is provided in the cavity. A bottom cover is fixed at the bottom of the straight switch body, and a gear connecting column is provided at the center of the bottom cover. An exhaust linkage mechanism is provided at one end of the straight switch body.

[0005] The locking device consists of a gear, a drive rack, a transmission rack, a connecting rod one, a connecting rod two, and a locking switch buckle. The gear is engaged with the gear connecting post on the bottom cover through the central post hole. The drive rack and the transmission rack mesh with the left and right sides of the gear, respectively. One end of the drive rack is fixed to the connecting rod one through the positioning post one, and one end of the transmission rack is fixed to the connecting rod two through the positioning post two. The drive rack, the transmission rack, the connecting rod one, and the connecting rod two are designed in a straight line. One end of the connecting rod one and the connecting rod two are equipped with a locking switch buckle, and a micro-pressure valve toggle switch lever is installed on the connecting rod two.

[0006] Preferably, the rack and pinion is provided with a lever hole, and a lever is engaged in the lever hole. The lever is an inclined rod, and one end of it is fixedly connected to the lower end of one end of the stand switch handle.

[0007] Preferably, the bottom cover is provided with guide and limiting protrusions on the left and right sides, which respectively fit against the sides of the drive rack, transmission rack, connecting rod one and connecting rod two, for guiding and limiting the movement direction of each component.

[0030] like Figures 1-12 As shown, this specific embodiment adopts the following technical solution: It includes a straight switch body 1, a positioning pin 2, a stand-up switch handle 3, a locking device 4, a bottom cover 5, and an exhaust linkage mechanism 6. The upper part of the straight switch body 1 is rotatably connected to the stand-up switch handle 3 through the positioning pin 2, so that the stand-up switch handle 3 can move up and down around the positioning pin 2. A cavity is provided at the bottom of the straight switch body 1, and a locking device 4 is provided in the cavity. A bottom cover 5 is fixed at the bottom of the straight switch body 1, and a gear connecting column 501 is provided at the center of the bottom cover 5. An exhaust linkage mechanism 6 is provided at one end of the straight switch body 1.

[0031] The locking device 4 consists of a gear 401, a driving rack 402, a transmission rack 403, a connecting rod 404, a connecting rod 405, and a locking switch 406. The gear 401 is engaged with the gear connecting post 501 of the bottom cover 5 through the central post hole and can rotate around the gear connecting post 501, driving the rack 402 and the transmission rack 403 to mesh with the left and right sides of the gear 401 respectively. One end of the driving rack 402 passes through the positioning post 406. 21 is fixedly engaged with connecting rod 404. One end of the transmission rack rod 403 is fixedly engaged with connecting rod 405 via positioning pin 4031. This causes the rack rod 402, transmission rack rod 403, connecting rod 404 and connecting rod 405 to form a straight structure. One end of both connecting rod 404 and connecting rod 405 is equipped with a locking switch buckle 406 for locking with the edge of the pot. Connecting rod 405 is equipped with a micro-pressure valve toggle switch rod 4051.

[0032] The rack and pinion 402 is provided with a toggle rod hole 4022, and a toggle rod 407 is engaged in the toggle rod hole 4022. The toggle rod 407 is an inclined rod, and one end of it is fixedly connected to the lower end of one end of the stand switch handle 3.

[0033] The bottom cover 5 has guide and limiting protrusions 502 on the left and right sides, which respectively fit into the sides of the drive rack 402, transmission rack 403, connecting rod one 404 and connecting rod two 405, and are used to guide and limit the movement direction of each component.

[0034] The bottom cover 5 has two positioning holes 503, which are fixedly connected to the two positioning pin holes 101 on the inner side of the main body of the linear switch 1 by screws.

[0035] The exhaust linkage mechanism 6 consists of an exhaust steel ball 601, a spring 602, an exhaust chamber 603, an exhaust filter cover 604, and a cover 605. The exhaust steel ball 601 and the spring 602 are arranged in the exhaust channel of the exhaust chamber 603, with the spring 602 located below the exhaust steel ball 601. The exhaust filter cover 604 is arranged above the exhaust chamber 603, and the cover 605 is arranged below the exhaust chamber 603. When the connecting rod 1 404 and the connecting rod 2 405 move, the micro-pressure valve toggles the switch rod 4051, which pushes the exhaust steel ball 601 to move up and down along the exhaust channel to achieve exhaust or closure.

[0036] When the stand-up switch handle 3 and the straight switch body 1 are in the open state, a sufficient stand-up angle is formed between the stand-up switch handle 3 and the straight switch body 1 to ensure that the pot lid can be stably placed on the table surface through the stand-up switch handle 3 after the lid is opened.

[0037] In this specific embodiment, when the stand-up switch handle 3 is moved upwards, the toggle lever 407 drives the rack 402 to move outwards, driving the gear 401 to rotate and causing the transmission rack 403 to move synchronously. This causes the connecting rod 404 and connecting rod 405 to move outwards, separating the locking switch buckle 406 from the pot rim. At the same time, the micro-pressure valve toggle the switch lever 4051 to push the venting steel ball 601 to release air. After opening the lid, the pot lid can be stood upright using the stand-up switch handle 3. When the stand-up switch handle 3 is moved downwards, the rack 402 moves inwards, causing the gear 401 to rotate in the opposite direction, causing the connecting rod 404 and connecting rod 405 to move inwards. The locking switch buckle 406 locks the pot rim, and the micro-pressure valve toggle the switch lever 4051 to reset. The venting steel ball 601 closes the air supply under the action of the spring 602.

[0038] The opening and venting process of this specific embodiment is as follows: 1. Move the upright switch handle 3 upwards. The upright switch handle 3 rotates upwards around the positioning pin 2, and the fixed toggle rod 407 (slanted rod) below it moves upwards accordingly; 2. The toggle rod 407 drives the driving rack rod 402, which is engaged with it, to move outwards along the guide limiting protrusion 502 on the bottom cover 5; 3. The rack rod 402 drives the drive gear 401 to rotate around the gear connecting post 501 on the bottom cover 5, and the gear 401 further engages to drive the transmission rack rod 403 to move outwards synchronously; 4. The rack rod 402 and the transmission rack rod 403 are driven outwards synchronously. 03. The connecting rods 404 and 405 move outwards respectively, causing the locking switch buckles 406 at the ends of the connecting rods 404 and 405 to separate from the pot body and rim, thus releasing the locking state; 5. At the same time, the micro-pressure valve at one end of the connecting rod 405 moves the switch rod 4051 outwards with the connecting rod, pushing the exhaust ball 601 in the exhaust channel downwards to compress the spring 602, thus opening the exhaust channel and achieving synchronous exhaust; 6. After exhaust is completed, the pot lid can be separated from the pot body. At this time, the pot lid can be placed upright on the countertop using the stand switch handle 3 to avoid direct contact between the pot lid opening and the stove.

[0039] The locking and air-tightening process of this specific embodiment is as follows: 1. After aligning and fastening the pot lid with the pot body, push down the movable switch handle 3. The movable switch handle 3 rotates downward around the positioning pin 2, and the fixed toggle rod 407 (slanted rod) below it moves downward accordingly; 2. The toggle rod 407 drives the driving rack rod 402, which is engaged with it, to move inward along the guide limiting protrusion 502 on the bottom cover 5; 3. The rack rod 402 drives the drive gear 401 to rotate in the opposite direction around the gear connecting column 501 on the bottom cover 5. The gear 401 further engages and drives the transmission rack rod 403 to move inward synchronously. 4. The rack and pinion 402 and the transmission rack and pinion 403 drive the connecting rod 1 404 and the connecting rod 2 405 to move inward, so that the locking switch buckle 406 at the end of the connecting rod 1 404 and the connecting rod 2 405 are tightly engaged with the pot body and the pot rim, thus completing the locking of the pot lid and the pot body; 5. At the same time, the micro-pressure valve toggle switch rod 4051 at one end of the connecting rod 2 405 moves inward with the connecting rod and separates from the exhaust steel ball 601. The exhaust steel ball 601 returns to its original position under the elastic force of the spring 602 below, blocking the exhaust channel, realizing air closure, and ensuring that a stable micro-pressure environment is formed inside the micro-pressure pot.
