[0003] A cooking pot cover is usually provided for the cooking pot. In order to improve the safety during the cooking of foods, the cooking pot cover is usually heavy so as to be able to bear a large pressure load during the cooking. The heavy cooking pot cover often causes inconvenience for workers to open the cover. The automatic equipment specially provided for opening the cover on the market is usually expensive, increasing the processing cost. CONTENT OF THE UTILITY MODEL

[0004] In order to improve the problem that the heavy cooking pot cover causes inconvenience for workers to open the cover, the application provides a zongzi cooking pot with automatic pressure relief and cover opening.

[0005] The application provides a zongzi cooking pot with automatic pressure relief and cover opening, which adopts the following technical scheme:

[0006] The zongzi cooking pot with automatic pressure relief and cover opening comprises a barrel body, a cover body, a pressure detector, a controller, a first linear driving element and a locking mechanism. The cover body is connected with a connecting arm, and the connecting arm is rotationally connected to the barrel body through a first rotation shaft. One end of the first linear driving element is hingedly connected to the barrel body, and the other end of the first linear driving element is hingedly connected to the connecting arm. The locking mechanism is arranged on the connecting arm and is used for locking the cover body and the barrel body. The pressure detector is arranged on the cover body, and a detection end of the pressure detector extends into the inside of the cover body. The controller is arranged on the barrel body, and the controller is electrically connected with the pressure detector, the first linear driving element and the locking mechanism.

[0007] By adopting the above technical scheme, when in use, the controller controls the first linear driving element to be elongated, thereby driving the connecting arm to swing around the first rotation shaft. The connecting arm drives the cover body to be closed on the opening of the barrel body in the process of swinging. Then the controller controls the locking mechanism to be started, so that the cover body is locked with the barrel body. When the pressure detector detects a preset pressure value during the cooking of foods, it means that the cooking of the foods is completed. The pressure detector sends an electric signal to the controller, thereby driving the first linear driving element and the locking mechanism to operate reversely, so that the cover body is opened. The cover body is high in automation, simple in structure and convenient to use in the whole process of opening and closing, and the problem that the heavy cooking pot cover causes inconvenience for workers to open the cover is improved.

[0008] Optionally, the locking mechanism comprises an arc-shaped clamping block and a power assembly, a second rotating shaft is fixed on the cover body along the self-axis direction, the second rotating shaft is rotationally connected to the connecting arm about the self-axis, and the arc-shaped clamping block is uniformly distributed on the circumferential wall of the cover body about the cover body axis.

[0009] By adopting the above technical scheme, the cover body is closed at the opening of the barrel body under the driving of the first linear driving member, the arc-shaped clamping block is clamped into the annular clamping groove through the sliding groove from top to bottom in the process of downward movement of the cover body, then the power assembly drives the cover body to rotate so that the arc-shaped clamping block is disengaged from the sliding groove and cannot be taken out, and the arc-shaped clamping block on the cover body is tightly pressed in the annular clamping groove under the steam pressure in the barrel body during steaming, so that the locking of the cover body is realized. The locking mechanism is simple and effective, and convenient to use.

[0010] Optionally, the power assembly comprises a second linear driving member, one end of the second linear driving member is hingedly connected to the connecting arm, the other end of the second linear driving member is hingedly connected to the cover body, and the second linear driving member is electrically connected to the controller.

[0011] By adopting the above technical scheme, the controller controls the second linear driving member to elongate or shorten, so as to drive the cover body to rotate about the second rotating shaft, without the need for manual participation, thereby reducing the work load of workers and the safety hidden danger brought by high-temperature and high-pressure working environment.

[0012] Optionally, the edges of the arc-shaped clamping block are chamfered.

[0013] By adopting the above technical scheme, the chamfering of the edges of the arc-shaped clamping block makes the arc-shaped clamping block more convenient to pass through the sliding groove, reduces the risk of being stuck in the moving process of the arc-shaped clamping block, and improves the reliability of the locking mechanism.

[0014] Optionally, a sealing gasket is arranged on the inner wall of the annular clamping groove.

[0015] By adopting the above technical scheme, the arrangement of the sealing gasket can improve the sealing performance of the cover body and the barrel body in the locked state, improve the steaming efficiency of food, and reduce safety hazards.

DETAILED DESCRIPTION

[0027] The application will be further described below in conjunction with the accompanying drawings. Figure 1 The application will be further described below in conjunction with the accompanying drawings.

[0028] The application discloses an automatic pressure relief and cover opening zongzi cooking pot. Referring to Figure 1 The automatic pressure relief and cover opening zongzi cooking pot comprises a barrel body 1, a cover body 2, a pressure detector 3, a controller 4, a first linear driving member 5 and a locking mechanism.

[0029] The barrel body 1 is open at the top end, and a first rotating shaft 11 is rotatably connected to the barrel body 1 in the transverse direction. A second rotating shaft 21 is welded and fixed to the center of the outer side of the cover body 2 along the axial direction of the cover body 2, and a connecting arm 22 is rotatably connected to the second rotating shaft 21 along the axial direction of the second rotating shaft 21. The middle part of the connecting arm 22 is welded and fixed to the first rotating shaft 11. The fixed end of the first linear driving member 5 is rotatably connected to the outer peripheral wall of the bottom of the barrel body 1, and the movable end of the first linear driving member 5 is rotatably connected to the end of the connecting wall away from the cover body 2. The rotating direction of the first linear driving member 5 is the same as that of the first rotating shaft 11, and the first linear driving member 5 is a hydraulic cylinder. When the first linear driving member 5 is elongated, the connecting arm 22 is swung around the first rotating shaft 11, and the cover body 2 is covered on the top end opening of the barrel body 1.

[0030] The pressure detector 3 is arranged on the cover body 2, and the detection end of the pressure detector 3 extends into the inside of the cover body 2. When the cover body 2 is in the covered state, the pressure detector 3 can detect the pressure value in the initial cooking state of the barrel body 1. The locking mechanism is arranged on the connecting arm 22 and is used for locking the cover body 2 and the barrel body 1 when the cover body 2 is in the covered state. The controller 4 is installed on the barrel body 1, and the controller 4 is electrically connected with the pressure detector 3, the first linear driving member 5 and the locking mechanism.

[0031] When the cover body 2 is closed, the controller 4 controls the first linear driving member 5 to be elongated, the connecting arm 22 is swung around the first rotating shaft 11, and the connecting arm 22 drives the cover body 2 to be covered on the opening of the barrel body 1 in the process of swinging. Then, the controller 4 controls the locking mechanism to be started so as to lock the cover body 2 and the barrel body 1. During the cooking process of food, when the pressure detector 3 detects the preset pressure value, it means that the food has been cooked completely. At this time, the pressure detector 3 sends an electric signal to the controller 4, the controller 4 controls the locking mechanism and the first linear driving member 5 to operate reversely in sequence, and then the unlocking and opening of the cover body 2 are realized. The cover body 2 has a high degree of automation in the whole opening and closing process, has a simple structure, is convenient to use, and improves the problem that the cover of a cooking pot with a large weight is inconvenient for a worker to open.

[0032] Further, in order to intuitively observe whether the cover 2 is closed, the connecting arm 22 is connected with a limiting block 23, and the barrel 1 is fixedly installed with a position sensor 12 and an indicator light 13. The position sensor 12 adopts a travel switch. When the cover 2 is in the closed state, the sensing end of the position sensor 12 abuts against the limiting block 23. The position sensor 12 is electrically connected with the indicator light 13. When the sensing end of the position sensor 12 abuts against the limiting block 23, it represents that the cover 2 is in the closed state. At this time, the position sensor 12 controls the indicator light 13 to emit a color of light, reminding the staff that the cover 2 is successfully closed. When the sensing end of the position sensor 12 is separated from the limiting block 23, the position sensor 12 controls the indicator light 13 to emit another color of light, reminding the staff that the cover 2 has been opened. The matching arrangement of the limiting block 23, the position sensor 12 and the indicator light 13 enables the staff to more intuitively observe whether the cover 2 is closed, and the use is convenient.

[0033] The locking mechanism comprises the arc-shaped clamping blocks 6 and a power assembly. The arc-shaped clamping blocks 6 are uniformly distributed on the peripheral wall of the cover 2 around the axis of the cover 2. In the present application, the arc-shaped clamping blocks 6 are provided with four, and in other embodiments, the arc-shaped clamping blocks 6 can also be provided with one, two or other quantities. An annular clamping groove 14 is formed on the inner peripheral wall of the barrel 1 close to the bottom opening position. Four sliding grooves 15 corresponding to the arc-shaped clamping blocks 6 are formed on the upper surface of the barrel 1. The size of the sliding grooves 15 is adapted to the shape of the arc-shaped clamping blocks 6, and the sliding grooves 15 are in communication with the annular clamping groove 14. The power assembly is arranged on the connecting arm 22 and is used to drive the cover 2 to rotate.

[0034] When the cover 2 moves downward under the action of the first linear driving member 5, the arc-shaped clamping blocks 6 on the cover 2 gradually pass through the sliding grooves 15 from top to bottom, and then enter the annular clamping groove 14. Then the controller 4 controls the power assembly to work, drives the cover 2 to rotate around the second rotating shaft 21, so that the arc-shaped clamping blocks 6 are dislocated with the sliding grooves 15, so that the arc-shaped clamping blocks 6 cannot be separated from the annular clamping groove 14, thereby realizing the locking of the position of the cover 2 and the barrel 1. When the food is in the cooking state, the cover 2 has a tendency to move upward under the pressure in the barrel 1, so that the arc-shaped clamping blocks 6 are pressed tightly in the annular clamping groove 14, thereby realizing the further locking of the cover 2. The locking mechanism is simple and effective, and the use is convenient.

[0035] Further, in order to facilitate the smooth sliding of the arc-shaped clamping blocks 6 in the sliding grooves 15, the edges of the arc-shaped clamping blocks 6 are provided with chamfers. In order to improve the sealing performance between the cover 2 and the barrel 1 when they are locked, a sealing gasket 7 is arranged on the inner wall of the annular clamping groove 14.

[0036] The power assembly comprises a second linear driving member 8, which is also a hydraulic cylinder, a fixed end of the second linear driving member 8 is rotationally connected with the connecting arm 22, and a movable end of the second linear driving member 8 is rotationally connected with the cover body 2, and the second linear driving member 8 is electrically connected with the controller 4. The controller 4 controls the second linear driving member 8 to be elongated or shortened, so as to drive the cover body 2 to rotate around the second rotation shaft 21, without the participation of workers, thereby reducing the working load of workers and the safety hazard caused by the high-temperature and high-pressure working environment.

[0037] In addition, the first rotation shaft 11 and the second rotation shaft 21 are both fixedly connected with a hand wheel 9, the hand wheel 9 is arranged to facilitate the opening of the cover body 2 in the case of power failure or damage of the electric element.

[0038] The implementation principle of the zongzi cooking pot with automatic pressure relief and cover opening in the embodiment of the application is as follows: when the cover body 2 needs to be closed, the controller 4 controls the first linear driving member 5 to be elongated, so as to drive the connecting arm 22 to swing around the first rotation shaft 11, and the connecting arm 22 drives the cover body 2 to be covered on the opening of the barrel body 1 in the process of swinging. In the process of downward movement of the cover body 2, the arc-shaped clamping block 6 on the cover body 2 gradually passes through the sliding groove 15 from top to bottom, and then enters the annular clamping groove 14. Then, the controller 4 controls the second linear driving member 8 to be elongated, so as to drive the cover body 2 to rotate around the second rotation shaft 21, so that the arc-shaped clamping block 6 is dislocated with the sliding groove 15, and the arc-shaped clamping block 6 cannot be taken out of the annular clamping groove 14, thereby realizing the locking of the position of the cover body 2 and the barrel body 1. When the pressure detector 3 detects a preset pressure value in the process of cooking food, it means that the food has been cooked, at this time, the pressure detector 3 sends an electric signal to the controller 4, and the controller 4 controls the second linear driving member 8 and the first linear driving member 5 to operate reversely in sequence, thereby realizing the unlocking and opening of the cover body 2. The whole process has a high degree of automation, a simple structure and convenient use, and improves the problem that the cover of a heavy cooking pot is inconvenient to open by workers.

[0039] The above are optional embodiments of the application, and do not limit the protection scope of the application, so that: any equivalent changes made according to the structure, shape and principle of the application should be covered within the protection scope of the application.
