[0055] The opening and closing mechanism proposed in this application, as shown in Figures 1 and 5, includes:

[0056] The opening and closing housing 20 includes an upper housing 21 and a lower housing 22. The upper housing 21 is rotatably connected to the lower housing 22. The upper housing 21 and the lower housing 22 enclose a cavity 20A. The upper housing 21 can be connected to the furnace cover 999, and the lower housing 22 can be connected to the furnace body 888.

[0057] The spring suspension assembly includes a fixed shaft 23, a movable shaft 24, a compression spring 25, a damping member 26, and a center rod 27. The two end structures of the fixed shaft 23 and the movable shaft 24 are respectively arranged on both sides of the overlapping portion formed by the upper shell 21 and the lower shell 22, and the movable shaft 24 can rotate around the fixed shaft 23 in the cavity 20A. The center rod 27 is limited in the cavity 20A of the lower shell 22 and is connected to the movable shaft 24. The compression spring 25 is sleeved on the center rod 27, and the damping member 26 is sleeved on the end of the center rod 27 away from the movable shaft 24.

[0058] The opening and closing mechanism has a hovering state. In the hovering state, the compression spring 25 can exert a force on the damping member 26 so that the inner wall of the damping member 26 abuts against the outer wall of the center rod 27 .

[0059] In the technical solution of the present application, an opening and closing mechanism is applied to a baking oven, which includes a stove cover 999 and a stove body 888 connected to the stove cover 999. The opening and closing mechanism includes an upper shell 21 that can be connected to the stove cover 999 and a lower shell 22 that can be connected to the stove body 888. After the upper shell 21 is connected to the lower shell 22, a cavity 20A is formed. The cavity 20A is used to install a spring suspension component. When the stove cover 999 is opened, the dynamic shaft 24 can rotate around the fixed shaft 23. The dynamic shaft 24 drives the center rod 27 to move, and the compression spring 25 on the outer peripheral side of the center rod 27 is deformed to produce an effect. Force, under the action of this force, the inner wall of the damping member 26 can abut against the outer wall of the center rod 27, preventing the compression spring 25 from further deformation. At this time, for the stove cover 999, its own gravity is equal to the elastic force of the compression spring 25 so that the stove cover 999 is in one state, which can achieve multi-angle position hovering. By controlling the opening degree of the stove cover 999 to meet the opening degree required by the operator, it is avoided that the opening angle is too large, resulting in a large amount of airflow entering the stove body 888 and causing the temperature in the stove to drop, which will not have a negative impact on the food being cooked and avoid affecting the taste of the food.

[0060] In this embodiment, the opening and closing housing 20 includes an upper housing 21 and a lower housing 22. The upper housing 21 is shaped with two mutually perpendicular surfaces both open. Similarly, the lower housing 22 is shaped with two mutually perpendicular surfaces both open. This allows the cavity 20A of the upper housing 21 to communicate with the cavity 20A of the lower housing 22, while also facilitating the installation of other structures of the opening and closing mechanism. The upper housing 21 can be rotatable relative to the lower housing 22 via a fixed shaft 23 and a movable shaft 24. Rotation between the upper and lower housings 21 and 22 can also be achieved via a hinge structure. The specific structure for achieving the rotatable connection between the upper and lower housings 21 and 22 is explained below.

[0061] The spring suspension assembly includes a fixed shaft 23, a movable shaft 24, two compression springs 25, two damping members 26 and two center rods 27. When the upper shell 21 is connected to the lower shell 22, the lower structure of the upper shell 21 and the upper structure of the lower shell 22 will be structurally covered to form a double-layer overlapping portion. It can be understood that the overlapping portion is essentially a double-layer structure composed of the upper shell 21 and the lower shell 22. Further, the lower shell 22 covers the upper shell 21, the outer layer of the overlapping portion is the upper structure of the lower shell 22, and the inner layer is the lower structure of the upper shell 21. A first limiting hole connecting the cavity 20A is provided at a corner position near the overlapping portion, and the two ends of the fixed shaft 23 are respectively limited at the two ends of the overlapping portion. In the first limiting hole on the side, in order to realize that the upper shell 21 can rotate with the oven cover 999 of the oven, an arc groove 22A is provided on the outer layer on the opposite sides of the overlapping part, and a second limiting hole connecting the arc groove 22A and the cavity 20A is provided on the inner layer. Here, the side of the arc groove 22A close to the first limiting hole is defined as the inner side, and the side away from the first limiting hole is defined as the outer side. The bending direction of the inner and outer sides is to bend toward the first limiting hole. The two ends of the movable shaft 24 are respectively limited to the arc groove 22A and the second limiting hole on both sides of the overlapping part. When the movable shaft 24 moves along the arc groove 22A, the upper shell 21 is rotated with the fixed shaft 23 as the center axis, thereby realizing the opening and closing of the oven cover 999; further, in the lower shell 2 Two center rods 27 connected to the movable shaft 24 are also provided in the cavity 20A of 2. Each center rod 27 includes a rod head 271 and a rod body 272. The rod head 271 includes a first connecting section 2711 and two second connecting sections 2712 bent to connect the two ends of the first connecting section 2711. The first connecting section 2711 and the two second connecting sections 2712 are each provided with a socket. The rod body 272 is limited to the socket of the first connecting section 2711. The center rod 27 is connected to the movable shaft 24 through the socket of the second connecting section 2712. A compression spring 25 is provided on the outside of each rod body 272. A damping member 26 is provided on the end of the compression spring 25 away from the movable shaft 24. The compression spring 25 can exert a force on the damping member 26. When the furnace cover 999 is opened, the upper cover will rotate together with the furnace cover 999, and the dynamic shaft 24 will rotate in the arc groove 22A with the fixed shaft 23 as the center axis, and then drive the center rod 27 to move upward. At this time, the compression spring 25 in the compressed state will exert a force on the damping member 26. Under the influence of this force, the inner wall of the damping member 26 will press against the outer wall of the rod body 272 of the center rod 27. At this time, the compression spring 25 no longer deforms because the compression spring 25 will support the dynamic shaft 24. Under this support, the furnace cover 999 is supported in a certain position, so that the furnace cover 999 is suspended.

[0062] In one embodiment of the present application, as shown in FIG. 3 , the spring suspension assembly further includes a spring adjustment nut 28 . The spring adjustment nut 28 is disposed at one end of the center rod 27 close to the dynamic shaft 24 .

[0063] In this embodiment, the spring suspension assembly further includes a spring adjustment nut 28. The end of the rod body 272 of the center rod 27 connected to the rod head 271 is provided with an external thread. The spring adjustment nut 28 is sleeved on the rod body 272 provided with the external thread. By rotating the spring adjustment nut 28, the initial state of the compression spring 25 can be adjusted. It should be explained that the initial state of the compression spring 25 referred to in this technical solution refers to the state when the opening and closing mechanism is applied to the oven, and the oven cover 999 and the oven body 888 are closed. By turning the spring adjustment nut 28, the opening and closing mechanism can be adapted to different ovens. Furthermore, a stopper 29 is provided between the spring adjustment nut 28 and the compression spring 25. The stopper 29 can increase the contact area with the compression spring 25 and improve the contact stability of the compression spring 25 during assembly.

[0064] In one embodiment of the present application, as shown in FIG. 2 and FIG. 3 , the outer diameter of the middle portion of the compression spring 25 is larger than the outer diameters of the two ends.

[0065] In this embodiment, the outer diameter of the middle part of the compression spring 25 is larger than the outer diameters at both ends. The compression spring 25 of this shape can provide a progressive elastic reaction force when subjected to external force. This progressive elasticity can provide better buffering and shock absorption effects when encountering large load changes. And because the outer diameter of the middle part of the compression spring 25 is larger, under the same external force, the deformation of the compression spring 25 is relatively small, which means that the compression spring 25 can provide greater elastic force within the same working range, thereby more effectively realizing the required elastic deformation, and playing a more stable supporting role for the furnace cover 999.

[0066] In one embodiment of the present application, as shown in FIG3 , the spring suspension assembly further includes a damping limit assembly, which is disposed in the cavity 20A; the damping limit assembly is sleeved on the damping member 26 so that the damping member 26 can abut against the center rod 27 in the suspended state.

[0067] In this embodiment, the spring suspension assembly also includes a damping limit assembly, which is arranged in the cavity 20A of the lower shell 22. The damping limit assembly is mainly used to limit the position of the damping member 26 to prevent the damping member 26 from being displaced under the action of the compression spring 25; the damping limit assembly includes a limit plate 30 and a damping limit sleeve 31. The limit plate 30 is fixed to the inner wall of the lower shell 22 by welding. The limit plate 30 is provided with a third limit hole at the position corresponding to the center rod 27, so that the rod body 272 passes through the limit plate 30, and the damping The limiting sleeve 31 is arranged on the side of the limiting plate 30 facing the compression spring 25 and is limited to the third limiting hole. The damping limiting sleeve 31 has a limiting chamber, and the damping member 26 is located in the limiting chamber, so that in the hovering state, the damping member 26 is subjected to the force of the compression spring 25 to stably abut the outer wall of the rod body 272 of the center rod 27 without displacement. A stop plate 29 is also provided on the side of the damping limiting sleeve 31 facing the compression spring 25. The function of the stop plate 29 is the same as that of the above-mentioned stop plate 29, and no further explanation will be given here.

[0068] In one embodiment of the present application, as shown in Figure 1, the opening and closing shell 20 also includes a connecting hoop 10, which includes a first hoop 11 and a second hoop 12. The first hoop 11 is detachably connected to the upper shell 21 and can be connected to the furnace cover 999, and the second hoop 12 is detachably connected to the lower shell 22 and can be connected to the furnace body 888.

[0069] In this embodiment, the opening and closing housing 20 further includes a connecting clamp 10, which includes a first clamp 11 and a second clamp 12. Each clamp forms a ring. The first clamp 11 is used to be mounted on the oven cover 999, and the second clamp 12 is mounted on the oven body 888. It is understood that the first clamp 11 and the second clamp 12 are distinguished because they are connected to different objects. Of course, the shape of the clamps can also be square or other shapes, depending on the shape of the oven to be used, and is not limited here. When the opening and closing mechanism is applied to the oven, the first clamp 11 can be fixedly mounted on the oven cover 999, and the second clamp 12 can be fixedly mounted on the oven body 888. If a component of the opening and closing mechanism is damaged and cannot be stably connected to the oven, the user can remove the connecting clamp 10 and replace the opening and closing mechanism in time to continue using the oven.

[0070] In one embodiment of the present application, as shown in Figure 1, the first clamp 11 and the second clamp 12 both include a surrounding section 101 and an adjustment section 102 bent on the outside of the two ends of the surrounding section 101, and the two adjustment sections 102 are provided with mutually aligned sockets; the opening and closing mechanism also includes a clamp adjustment component, each clamp adjustment component connects the two adjustment sections 102 of a connecting clamp 10 and can adjust the distance between the two adjustment sections 102.

[0071] In this embodiment, the first clamp 11 and the second clamp 12 both include a surrounding section 101 and an adjustment section 102 bent on the outside of the two ends of the surrounding section 101. The surrounding section 101 is used to connect the oven, and the adjustment sections 102 at both ends of the surrounding section 101 are used to connect the two ends of the surrounding section 101 to form a closed structure of the surrounding section 101. Each adjustment section 102 is provided with a socket. The clamp adjustment component of the opening and closing mechanism can be inserted into the socket to adjust the distance between the two adjustment sections 102 of the first clamp 11 and the second clamp 12, so that an opening and closing mechanism can be adapted to ovens of the same shape but different models. At the same time, the clamp adjustment component can also strengthen the connection force of the connecting clamp 10 to the oven to prevent the problem of insufficient connection force causing the connecting clamp 10 to fall off the oven. It is understood that the clamp adjustment assembly can be in the form of a straight rod with external threads on both ends and two nuts 104, or in the form of a bolt 105 and nut 104, without limitation. The clamp adjustment assembly only needs to be able to adjust the distance between the two aligned adjustment segments 102. Furthermore, reinforcing ribs are provided in the area where the adjustment segment 102 bends and connects to the surrounding segment 101.
