Description

Technical Field

[0001] The utility model relates to the field of pot bodies such as electric rice cookers or pressure cookers, and in particular to a novel protective device for the pot body. Background Art

[0002] Most heating devices on the market with inner covers, such as pressure cookers, require two steps to open and close the cover. Generally, a cover opening button and a rotary handle are required to realize the closing of the cover and the inner pot, which makes disassembly inconvenient. In addition, there are no restrictions during disassembly, which may cause users to accidentally open the pot when it is full of pressure, resulting in safety accidents. Utility Model Content

[0003] In order to solve the above problems, the present technical solution provides a new type of protection device for a pot body.

[0004] To achieve the above purpose, the technical solution is as follows:

[0005] A novel protective device for a pot body, comprising at least:

[0006] A rotary handle, the rotary handle is used to drive the rotary arm to perform rotary motion, and a gear is provided at the lower end of the rotary handle;

[0007] It also includes a rack connecting rod, which is provided with a rack meshing with the gear. A float through hole is provided on one side of the rack connecting rod. The float through hole is connected to a sliding hole. When the float switch is working, it extends into the float through hole to prevent the rotating handle from rotating.

[0008] In some embodiments, the diameter of the float through hole is consistent with the diameter of the floating part of the float switch, and the diameter of the sliding hole is smaller than the diameter of the float through hole.

[0009] In some embodiments, a limiting groove is provided on the other side of the rack connecting rod, and a positioning column provided on the surface cover is matched in the limiting groove.

[0010] In some embodiments, the middle portion of the rack connecting rod is transitioned through an inclined surface.

[0011] The beneficial effects of this application are:

[0012] Since the rotary handle drives the rotary arm to rotate and then drives the rotary cover to rotate, the cover can be removed, but there is a safety risk. Therefore, the present application makes an improvement. When the pot body is working, the pressure will drive the float switch to float, and then the float switch enters the float through hole. Since the rack connecting rod is restricted and cannot move, the rotary handle connected by meshing cannot rotate, thereby ensuring that the cover cannot be removed during work. When the pot body is finished working, the float switch withdraws from the float through hole. At this time, the upper end of the float switch can move freely in the sliding hole, so that the rotary handle can be rotated for removal. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0019] Please refer to Figure 1-4 As shown, a novel protective device for a pot body at least comprises:

[0020] A rotary handle 101, the rotary handle 101 is used to drive the rotary arm 102 to perform a rotary motion, and a gear 107 is provided at the lower end of the rotary handle 101;

[0021] It also includes a rack connecting rod 500, which is provided with a rack 501 meshing with the gear 107. A float through hole 502 is provided on one side of the rack connecting rod 500. The float through hole 502 is connected to a sliding hole 503. When the float switch 504 is working, it extends into the float through hole 502 to prevent the handle 101 from rotating.

[0022] Since the rotary handle drives the rotary arm to rotate and then drives the rotary cover to rotate, the cover can be removed, but there is a safety risk. Therefore, the present application makes an improvement. When the pot body is working, the pressure will drive the float switch to float, and then the float switch enters the float through hole. Since the rack connecting rod is restricted and cannot move, the rotary handle connected by meshing cannot rotate, thereby ensuring that the cover cannot be removed during work. When the pot body is finished working, the float switch withdraws from the float through hole. At this time, the upper end of the float switch can move freely in the sliding hole, so that the rotary handle can be rotated for removal.

[0023] In this embodiment, the aperture of the float through hole 502 is consistent with the aperture of the floating part of the float switch 504, and the aperture of the sliding hole 503 is smaller than the aperture of the float through hole 502. After the float switch floats, it extends into the float through hole to clamp it so that the rack connecting rod cannot slide. When the float switch moves down, its thinner part can enter the sliding hole. Due to the difference in the aperture sizes of the two holes, the rack connecting rod can slide with it.

[0024] In this embodiment, a limiting groove 505 is provided on the other side of the rack connecting rod 500, and a positioning column 506 provided on the surface cover is matched in the limiting groove 505 to limit the sliding direction of the rack connecting rod.

[0025] In this embodiment, the middle portion of the rack connecting rod 500 is transitioned through an inclined surface.

[0026] In this embodiment, it also includes:

[0027] A cover 100, wherein a buckle portion 200 is provided at the lower end of the cover 100;

[0028] The locking structure 300 is arranged on the pot body. When the locking structure 300 is in an extended state, it is locked with the buckle portion 200. When the locking structure 300 is in a retracted state, the cover 100 is detachable.

[0029] The rotary cover 400 is rotatably disposed and is located inside the surface cover 100 . The outer wall of the rotary cover 400 is provided with a limiting portion 401 that cooperates with the locking structure 300 to keep the locking structure 300 in an extended or retracted state.

[0030] The present application discloses a novel snap-fitting device that combines two processes into one, bringing a more convenient experience to the switch cover. Usually, the limit part pushes the locking structure to extend and fix it with the snap part. At this time, it is in a locked state and the cover cannot be removed. When the user rotates the rotary cover, the limit part leaves the locking structure to make the locking structure retreat, so that the locking structure exits the snap part. At this time, it is in an unlocked state and the user can remove the cover. The whole process can be achieved in one step.

[0031] In this embodiment, the face cover 100 is provided with a rotary handle 101, and the rotary handle 101 is provided with a rotating arm 102. The rotating arm 102 is used to drive the rotary cover 400 to rotate. As one of the means to drive the rotary cover to rotate, the rotatable rotary handle drives the rotating arm to rotate accordingly, and then the rotating arm will drive the rotation to rotate so that the limiting part is close to or away from the locking structure.

[0032] In this embodiment, the face cover 100 is provided with a first slide groove 103, the rotary cover 400 is provided with a limiting column 104 extending out of the first slide groove 103, and the rotating arm 102 is provided with a second slide groove 105 for the limiting column 104 to pass through. The first slide groove allows the limiting column to slide in the position where it is opened, and the second slide groove provided in addition allows the limiting column to slide with room for movement.

[0033] In this embodiment, the cover 100 is provided with a rotating base 106 for rotatably mounting the rotating handle 101 .

[0034] In this embodiment, the locking structure 300 includes:

[0035] A locking base 301, wherein two ends of the locking base 301 are respectively provided with a first through hole and a second through hole;

[0036] The slide rod 302 has one end extending out of the first through hole and cooperating with the limiting portion 401 , and the other end extending out of the second through hole and cooperating with the buckle portion 200 . A return spring 303 is sleeved on one end of the slide rod 302 close to the buckle portion 200 .

[0037] When the limit part is opposite to one end of the slide rod, the other end of the slide rod slides toward the buckle part, and the spring is compressed at this time, so that the other end of the slide rod cooperates with the buckle part, thereby fixing the cover. The limit part leaves the slide rod by rotating the cover, and then the spring recovers to drive the slide rod out of the buckle part, so that the cover can be removed.

[0038] In this embodiment, the corners of the limiting portion 401 are in the form of arc transitions, and the arcs are used to play a guiding role, so that the limiting portion is easier to cooperate with the sliding rod.

[0039] The above description is only a preferred embodiment of the present application and is not intended to limit the scope of implementation of the present application. Other principles and basic structures that are the same or similar to those of the present application are within the protection scope of the present application.
