Description

Technical Field

[0001] The utility model specifically relates to a pressure cooker capable of releasing pressure. Background Art

[0002] A pressure rice cooker, or a pressure cooker with rice cooker function, is a common household appliance. In the past, there was a patent number CN202221125149.9, which is a cooking utensil capable of switching between electric pressure cooker and electric rice cooker functions. The cooking utensil pushes the lever through the dial block to lift or lower the exhaust valve block, that is, the electric pressure cooker or electric rice cooker function can be switched by turning the handle. The working mode of the traditional cooking utensil depends on whether the exhaust valve block is closed. In order to solve the problem of how to switch the working mode, the inventor has previously invented a pressure cooker structure for switching the switchable cooking mode. The structure rotates the dial member and presses one end of the seesaw, so that the other end of the seesaw is lifted and the exhaust valve block is lifted. At the same time, the sliding member is driven to move by the dial member, and a proximity sensor is provided on the pressure cooker for sensing the approach or distance of the sliding member. In this way, the signal can be collected after the dial member is operated and transmitted to the internal processor of the pressure cooker, so that the operator's operation can be recognized in time, and the working mode of the pressure cooker can be adjusted. However, in this type of pressure cooker, the friction force is large when the toggle member pushes the sliding member, which makes the operation not smooth and the sliding member does not move smoothly, which is not conducive to the accuracy of the proximity sensor for the sliding member.

[0003] The utility model is produced based on the above-mentioned shortcomings. Utility Model Content

[0004] The utility model aims to overcome the deficiencies of the prior art and provide a pressure cooker capable of releasing pressure which has smoother operation.

They do not indicate the unique or absolute positional relationship between the various components. They are only one of the implementation methods of the utility model and are not a limitation on its implementation method.

[0028] like Figures 1 to 6As shown, a pressure cooker with pressure relief comprises a pot body 1 and a pot cover 2 which can be covered thereon, the top of the pot cover 2 is provided with an exhaust valve block 21 which can slide up and down relative to the pot cover 2, the pot cover 2 is also provided with a knob 3 and a seesaw 4, the knob 3 is rotatably connected to the pot cover 2, the middle part of the seesaw 4 is rotatably connected to the pot cover 2, the front part of the seesaw 4 is located below the knob 3 and the rear part of the seesaw 4 is located below the exhaust valve block 21, the bottom of the knob 3 is provided with a pressing part 31 which can press down the front part of the seesaw 4 during its rotation and thus make the rear part of the seesaw 4 lift up the exhaust valve block 21, the pot cover 2 is also provided with a slide seat 5, the slide seat 5 is provided with a sliding member 6 which can slide relative to the slide seat, the knob 3 is provided with a matching window 31, and the sliding member 6 has a matching window 32. An insert rod 61 is provided which extends into the matching window 31, so that the knob 3 can push the sliding member 6 to slide after being rotated to a preset angle. The lower end of the sliding member 6 is connected to a sensing member 60. The pot body 1 is provided with a proximity sensor 11 for sensing the sensing member 60. The proximity sensor 11 can be a general photoelectric sensor, capacitive sensor, magnetic sensor, ultrasonic sensor, electric induction sensor, etc., as long as it can sense the sensing member 60 approaching or moving away. In this embodiment, the proximity sensor 11 is an inductive sensor, and the sensing member 60 is a general metal block such as a steel block or an iron block. Compared with proximity sensors such as photoelectric sensors, capacitive sensors, magnetic sensors, and ultrasonic sensors, inductive sensors can have better penetration and can detect metal blocks through thicker walls. Figure 7 As shown, Figure 7 This is a view from the top, and its counterclockwise and clockwise directions are opposite to those from the top, so the following description is based on the view Figure 7The explanation is based on the direction indicated. When in use, the knob member 3 is manually turned counterclockwise to rotate, and the seesaw member 4 is pushed during the rotation of the knob member 3 to lift the exhaust valve block 21, so that the pressure cooker is in a deflated state. At the same time, the sensing member 60 is pushed away from the proximity sensor 11 during the rotation of the knob member 3. After detecting that the sliding member 24 is away, the proximity sensor 11 sends a signal to the control module 12, and the control module 12 sets the working mode of the pressure cooker to the rice cooker mode. Similarly, when the knob member 3 is manually turned clockwise, the exhaust valve block 21 falls after the top pressure part 221 leaves the seesaw member 2, so that the pressure cooker is in a closed state. At the same time, the sensing member 60 is pushed close to the proximity sensor 11 during the rotation of the knob member 3. After detecting that the sliding member 24 is close, the proximity sensor 11 sends a signal to the control module 12, and the control module 12 sets the working mode of the pressure cooker to the pressure cooker mode. In the above process, when the knob part 3 is rotated by a certain angle, the edge of the matching window 31 abuts against the insertion rod 61 and then pushes the sliding part 6 to slide. The edge size of the matching window 31 is pre-designed, so that when the knob part 3 is rotated by a preset angle, the sliding part 6 can be pushed to slide. In this way, the structure is stable, the movement is smooth and it is more convenient to operate.

[0029] As a preferred solution of this embodiment, Figures 4 to 6 As shown, the slide seat 5 is provided with an outer circular plate 51, the bottom of the knob member 3 is provided with an inner circular plate 32 inserted into the outer circular plate 51, and the knob member 3 is provided with a clamping plate 33 on the outer side of the inner circular plate 32, and the clamping plate 33 and the outer side surface of the inner circular plate 32 form a clamping groove 330 for clamping the outer circular plate 51. The slide seat 5 is provided with an outer circular plate 51, which is a part of the whole structure and may play a role of guiding, supporting or limiting. The bottom of the knob member 3 An inner ring plate 32 is configured, and the inner ring plate 32 is designed to be inserted into the above-mentioned outer ring plate 51, thus forming a nested connection structure. A clamping plate 33 is also provided on the outer side of the inner ring plate 32 of the knob member 3. When the knob member 3 rotates, the clamping plate 33 will move accordingly. The clamping plate 33 and the outer side surface of the inner ring plate 32 together form a clamping groove 330 for clamping the outer ring plate 51, so that the knob member 3 is stably and firmly rotatably connected to the slide groove seat 5.

[0030] As a preferred solution of this embodiment, Figures 4 to 6 As shown, the clamping plate 33 is arc-shaped and protrudes toward the slide slot seat 5. Preferably, the arched portion of the clamping plate 33 protrudes toward the slide slot seat 5 and then abuts against the upper surface of the slide slot seat 5, thereby improving stability, and reducing friction by the arc-shaped surface of the clamping plate 33 abutting against the upper surface of the slide slot seat 5.

[0031] As a preferred solution of this embodiment, Figures 4 to 6As shown, a downwardly projecting limiting protrusion 331 is provided at the lower end of the clamping plate 33, and a first limiting groove 501 and a second limiting groove 502 for the limiting protrusion 331 to enter are provided on the slide seat 5. When the knob member 3 is rotated so that the limiting protrusion 331 enters the first limiting groove 501, the sensing member 60 is away from the proximity sensor 11; when the knob member 3 is rotated so that the limiting protrusion 331 enters the second limiting groove 502, the sensing member 60 is close to the proximity sensor 11. In this way, when in use, the limiting protrusion 331 can be stuck in the first limiting groove 501 or the second limiting groove 502 after the knob member 3 is rotated by a certain angle. This design not only provides obvious physical limiting and operation feedback, such as informing the user that the preset position has been reached through a slight vibration during limiting, but also greatly improves the ability to accurately position the rotation position of the knob member 3.

[0032] As a preferred solution of this embodiment, Figures 4 to 6 As shown, the knob member 3 is provided with two clamping plates 33, and the slide seat 5 is correspondingly provided with two first limiting grooves 501 and two second limiting grooves 502, so as to further improve the stability of the structure.

The pressing protrusion 631 contacts the bottom of the sliding groove 52. On the one hand, the pressing protrusion 631 contacts the bottom of the sliding groove 52, which reduces the friction; on the other hand, the elastic characteristics of the spring piece part 63 can buffer the impact of the sliding part 62 during the sliding process to a certain extent. The pressing protrusion 631 converts the sliding friction into rolling friction or point contact friction, thereby reducing the sliding resistance and improving the movement smoothness and service life of the sliding parts. In addition, such a structure also helps to improve the accuracy and stability of the equipment operation.

[0034] As a preferred solution of this embodiment, Figures 4 to 6 As shown, the slide groove seat 5 is provided with a slide groove 52 for the slide member 6 to slide, the slide groove 52 is arc-shaped, and the slide member 6 has a slide portion 62 that matches the shape of the slide groove 52 and can slide in the slide groove 52. The shape of a part of the slide member 6, namely the slide portion 62, is precisely matched with the arc profile of the slide groove 52, ensuring that the slide portion 62 can slide smoothly along the arc path in the slide groove 52. This matching design can ensure effective contact and guiding between the slide member 6 and the slide groove seat 5, realize the preset movement function, and may reduce wear and vibration during the movement, thereby improving the stability and life of the entire device.

[0035] As a preferred solution of this embodiment, Figures 4 to 6 As shown, the sliding member 6 also has a curved arm 64 connected to the sliding portion 62 and extending downward, and the sensing member 60 is connected to the lower end of the curved arm 64 .

[0036] As a preferred solution of this embodiment, Figures 4 to 6 As shown, the slide seat 5 is provided with an extension window 54 for the curved arm 64 to extend toward, and the movement of the moving part 6 is further restricted by the extension window 54, thereby improving the stability and reliability of the structure.
