Abstract
Description
Technical Field
[0001] This utility model relates to the field of pressure cookers, and in particular to a pressure cooker. Background Technology
[0002] Existing pressure cookers are equipped with a safety locking mechanism that prevents the lid from being opened when there is high-pressure steam inside the pot.
[0003] For example, patent document CN111568169A discloses a pot lid safety locking structure and an electric pressure cooker using this structure. The pot lid safety locking structure includes a movable push rod and a push rod connecting plate. One end of the push rod connecting plate is fixedly connected to the movable push rod, and the other end of the push rod connecting plate has a locking hole. The movable push rod is equipped with a first spring. The pot lid is equipped with a steam actuation mechanism, which includes a heat-conducting shell, a stop rod, a first magnet, a second magnet, and a driving component. The driving component can drive the first magnet and the second magnet to separate, thereby driving the stop rod to insert into the locking hole.
[0004] However, the aforementioned technology alters the magnet's magnetism by transferring heat to it, thereby using the difference between the magnet's magnetic force and the spring force to control the movement of the stop lever, achieving locking and unlocking. Since temperature transfer is significantly affected by external factors, such as external temperature and dust accumulated over time, variations in magnetic field can occur, making it impossible to accurately control locking and unlocking based on the pot's internal temperature.
[0005] Therefore, a pressure cooker is proposed to solve the above-mentioned technical problems. Utility Model Content
[0006] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a pressure cooker that can accurately control locking and unlocking according to the pressure and temperature inside the pot, thus ensuring safe use.
[0007] The technical solution adopted by this utility model to solve the problem is: a pressure cooker, including: a pot body and a pot lid, a temperature sensor is provided on the inner wall of the pot body, an electromagnetic valve and a top rod are provided on the pot body, the top rod is drivenly connected to the electromagnetic valve, a connecting rod is slidably installed inside the pot lid, a pin is provided on the connecting rod, a locking block is provided inside the pot body, the pin corresponds to the locking block, a top block is provided inside the pot lid, a protrusion is provided on the top block, and the protrusion corresponds to the bottom of the connecting rod.
[0008] As a further improvement to the above technical solution, the pot body is provided with an installation ring, the installation ring is provided with a housing, the solenoid valve and the push rod are both provided inside the housing, and the housing is provided with a first spring, the two ends of the first spring respectively abutting against the solenoid valve and the push rod.
[0009] As a further improvement to the above technical solution, a second spring is provided inside the pot lid, and the two ends of the second spring abut against the pot lid and the top block, respectively.
[0010] As a further improvement to the above technical solution, a wedge-shaped block is provided at one end of the connecting rod, and a button is slidably installed on the pot lid, with the bottom end of the button contacting the inclined surface of the wedge-shaped block.
[0011] As a further improvement to the above technical solution, the pot lid is provided with a guide shaft, the connecting rod is provided with a groove, and the guide shaft is vertically slidably connected to the groove.
[0012] The beneficial effects of this utility model are: by controlling the locking and unlocking of the pin through the solenoid valve, the locking and unlocking can be accurately controlled according to the pressure and temperature inside the pot, thus ensuring safe use.

If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.
[0019] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0020] Reference Figures 1 to 5 A pressure cooker includes: a pot body 1 and a pot lid 7. A temperature sensor is provided on the inner wall of the pot body 1. A solenoid valve 2 and a push rod 3 are provided on the pot body 1. The push rod 3 is connected to the solenoid valve 2 in a transmission manner. A connecting rod 5 is slidably installed inside the pot lid 7. A pin 6 is provided on the connecting rod 5. A locking block 13 is provided inside the pot body 1. The pin 6 corresponds to the locking block 13. A top block 4 is provided inside the pot lid 7. A protrusion 41 is provided on the top block 4. The protrusion 41 corresponds to the bottom of the connecting rod 5. The solenoid valve 2 is controlled by a temperature sensor. The working principle is based on existing technology: the data detected by the temperature and pressure sensors are converted into electrical signals, which are then used by the controller to operate the solenoid valve 2. During use, the connecting rod 5 is manually slidable. When the connecting rod 5 is on the right side, the pin 6 engages with the locking block 13, preventing the lid 7 from being rotated open. When the connecting rod 5 slides to the left, the pin 6 follows, disengaging from the locking block 13, allowing the lid 7 to be rotated open. When the temperature or pressure inside the pot is detected to be too high, the solenoid valve 2 is activated. The solenoid valve 2 drives the top rod 3 upwards, which in turn drives the top block 4 upwards. The protrusion 41 on the top block 4 abuts against the connecting rod 5, preventing it from moving to the left and thus preventing the lid 7 from opening, ensuring safe operation.
[0021] In a preferred embodiment, the pot body 1 is provided with a mounting ring 11, and a housing 12 is provided on the mounting ring 11. The solenoid valve 2 and the push rod 3 are both located inside the housing 12. A first spring 31 is provided inside the housing 12, and the two ends of the first spring 31 abut against the solenoid valve 2 and the push rod 3, respectively. When the solenoid valve 2 is closed, the push rod 3 can be reset by the first spring 31.
[0022] In a preferred embodiment, a second spring 42 is provided inside the pot lid 7, with both ends of the second spring 42 abutting against the pot lid 7 and the top block 4, respectively. When the solenoid valve 2 is closed, the second spring 42 can be used to control the top block 4 to reset, thereby preventing the protrusion 41 from abutting against the connecting rod 5.
[0023] In a preferred embodiment, a wedge-shaped block 51 is provided at one end of the connecting rod 5, and a button 71 is slidably mounted on the pot lid 7. The bottom end of the button 71 contacts the inclined surface of the wedge-shaped block 51. When the protrusion 41 is no longer in contact with the connecting rod 5, pressing the button 71 pushes the wedge-shaped block 51 to move to the left. The wedge-shaped block 51 drives the connecting rod 5 and the pin 6 to move to the left, and the pin 6 moves away from the locking block 13, allowing the pot lid 7 to be rotated and opened.
[0024] In a preferred embodiment, the pot lid 7 is provided with a guide shaft 72, and the connecting rod 5 is provided with a groove 52, with the guide shaft 72 and the groove 52 being vertically slidably connected.
[0025] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
