The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments.

[0053] The embodiment of the present application provides a locking mechanism, such as Figure 1-6 As shown, the invention mainly comprises a guide member 1, a rotating member 2, a transmission member 3, and a first position-limiting member 4. The guide member 1 comprises a first sliding portion 121; the rotating member 2 is arranged corresponding to the guide member 1 and comprises a locking portion 221, which is used to move along the first sliding portion 121 to a locking position to achieve locking between the guide member 1 and the rotating member 2; the transmission member 3 is in transmission connection with the rotating member 2, so that the transmission member 3 moves in a direction away from the rotating member 2; and the first position-limiting member 4 is arranged on the transmission member 3 and in transmission connection with the transmission member 3, so that the first position-limiting member 4 moves in a direction away from the transmission member 3.

[0054] In some possible embodiments, such as Figure 1-3As shown, the guide member 1 includes a first guide portion 11 and a second guide portion 12 connected to each other. The main bodies of the first guide portion 11 and the second guide portion 12 are both circular plate-shaped, and a gap is provided between the first guide portion 11 and the second guide portion 12. The rotating member 2 includes a first rotating portion 21 and a second rotating portion 22 connected to each other. The main bodies of the first rotating portion 21 and the second rotating portion 22 are both circular plate-shaped, and a gap is provided between the first rotating portion 21 and the second rotating portion 22, so that the second rotating portion 22 is provided in the gap between the first guide portion 11 and the second guide portion 12, and the first guide portion 11 is provided in the gap between the first rotating portion 21 and the second rotating portion 22. The first rotating portion 21, the second rotating portion 22, the first guide portion 11 and the second guide portion 12 are coaxially arranged.

[0055] The transmission member 3 is disposed on a side of the second guide portion 12 away from the rotating member 2. The rotating member 2 and the transmission member 3 can be connected in a transmission manner within the guide member 1. The rotating member 2 can rotate in a first direction or a second direction under the action of an external force. Optionally, the first direction is clockwise and the second direction is counterclockwise; alternatively, the first direction is counterclockwise and the second direction is clockwise.

[0056] Through a locking mechanism provided by the present application, the rotating member 2 rotates along the first direction, driving the transmission member 3 to move in a direction away from the rotating member 2, so that the moving transmission member 3 drives the first limit member to move in a direction away from the transmission member 3, and the rotating member 2 synchronously drives the locking portion 221 to move along the first sliding portion 121 to the locking position. When the locking portion 221 reaches the locking position, the locking portion 221 is force balanced and stops rotating, so that the positions of the rotating member 2 and the guide member 1 are relatively fixed, achieving locking. At the same time, the first limit member stops moving, and the positions of the first limit member and the transmission member 3 are relatively fixed; the rotating member 2 rotates in a second direction opposite to the first direction, breaking the force balance of the locking portion 221, and driving the locking portion 221 away from the locking position to achieve unlocking.

[0057] In order to facilitate the description of the relationship between the various components in this embodiment, Figure 5 、 6 , 13 and 17, the structural part related to the guide member 1 does not show the first rotating part 21, and the structural part related to the rotating member 2 does not show the first guide part 11.

[0058] As an optional implementation, Figure 4As shown, the rotating member 2 includes a first surface 222 and a first transmission part 223; the first transmission part 223 and the locking part 221 both protrude from the first surface 222, and the first transmission part 223 and the locking part 221 are arranged at intervals; a second surface 2231 is provided on the first transmission part 223, the second surface 2231 intersects with the first surface 222, and the second surface 2231 is transmission-connected to the transmission member 3; during the rotation stage of the rotating member 2, the transmission member 3 slides relatively along the second surface 2231, so that the transmission member 3 moves in the direction of approaching or moving away from the rotating member 2.

[0059] In some possible embodiments, such as Figure 4 As shown, the first surface 222 is a plane and is arranged on the second rotating part 22. The locking part 221 can be a cylinder protruding from the first surface 222, and the axial direction of the cylinder is perpendicular to the first surface 222. The first transmission part 223 is located at the center of the first surface 222. The first transmission part 223 is connected to the transmission member 3 through the second surface 2231. The second surface 2231 can be a curved surface. During the rotation of the rotating member 2, the rotating member 2 drives the first transmission part 223 to rotate synchronously, so as to realize the relative sliding of the transmission member 3 along the second surface 2231. When the rotating member 2 rotates in the first direction, the second surface 2231 acts on the transmission member 3, and through the relative sliding between the transmission member 3 and the second surface 2231, a force is provided for the transmission member 3 to move in the direction away from the rotating member 2, so as to push the transmission member 3 in the direction away from the rotating member 2.

[0060] As an optional implementation, Figure 5 As shown, the guide member 1 includes a third surface 122 and a mounting portion; the mounting portion is recessed in the third surface 122 and is spaced apart from the first sliding portion 121; the third surface 122 is arranged toward the first surface 222, at least part of the first transmission portion 223 is arranged in the mounting portion, and at least the locking portion 221 is accommodated in the first sliding portion 121.

[0061] In some possible embodiments, such as Figure 5 and 6 As shown, the first sliding portion 121 is provided with a third sliding surface 123, which can be a curved surface, or a spherical surface. The side surface of the locking portion 221 can slide along the third sliding surface 123, so that the locking portion 221 moves along the circumference, thereby achieving synchronous rotation of the locking portion 221 and the rotating member 2. Optionally, the side of the locking portion 221 away from the first surface 222 is not connected to the first sliding portion 121 to reduce the resistance encountered during rotation. The mounting portion can be a recessed portion recessed in the third surface 122, or a hollow structure extending through the thickness of the guide member 1 to form a space for accommodating the first transmission portion 223; the first sliding portion 121 can be a recessed portion recessed in the third surface 122, or a hollow structure extending through the thickness of the guide member 1 to form a space for accommodating the locking portion 221.

[0062] As an optional implementation, Figure 7 As shown, the rotating member 2 also includes a limiting portion 225; the limiting portion 225 protrudes from the first surface 222 and is arranged around the first transmission portion 223 and the locking portion 221; the limiting portion 225 is provided with a first sliding surface 226, the first sliding surface 226 intersects with the first surface 222, and the first sliding surface 226 is slidably connected to the guide member 1.

[0063] Based on the above embodiments, in some possible embodiments, such as Figure 7 As shown, the limiting portion 225 is annular in shape, surrounding the first transmission portion 223 and the locking portion 221. The limiting portion 225 protrudes from the first surface 222 in a direction perpendicular to the first surface 222. The inner wall surface of the limiting portion 225 serves as the first sliding surface 226. Optionally, the limiting portion 225 is a closed ring; alternatively, the limiting portion 225 is a non-closed ring.

[0064] As an optional implementation method, Figure 8 As shown, the guide member 1 also includes a second sliding surface 128; the second sliding surface 128 is arranged at the edge of the guide member 1 and intersects with the third surface 122; the guide member 1 is accommodated in the recess defined by the first surface 222 and the limiting portion 225, and the second sliding surface 128 is slidably connected to the first sliding surface 226.

[0065] Based on the above embodiments, in some possible embodiments, such as Figure 8 As shown, a second sliding surface 128 is provided along the edge of the guide member 1. The second sliding surface 128 is a curved surface and is adapted to the first sliding surface 226. The guide member 1 is accommodated in the recess defined by the first surface 222 and the stopper 225. When the rotating member 2 rotates, the rotating member 2 rotates relative to the guide member 1 along the second sliding surface 128.

[0066] Alternatively, as Figure 8 As shown, in order to reduce the weight of the guide member 1 and to facilitate its accommodation in the recess defined by the first surface 222 and the limiting portion 225, the disc-shaped guide member 1 in the aforementioned embodiment is designed as a block-shaped guide member 1, and second sliding surfaces 128 are provided on opposite sides of the block-shaped guide member 1, and the two second sliding surfaces 128 are located on the same circumference.

[0067] As an optional implementation, Figure 7 and 8 As shown, the guide member 1 includes a fourth surface 124 and a second sliding portion 125; the second sliding portion 125 is recessed in the fourth surface 124; the fourth surface 124 is arranged toward the transmission member 3, and at least part of the transmission member 3 is accommodated in the second sliding portion 125; the second sliding portion 125 is communicated with the mounting portion, part of the transmission member 3 is located in the mounting portion, and the transmission member 3 is transmission-connected to the first transmission portion 223.

[0068] In some possible embodiments, such as Figure 7 and 8 As shown, the second sliding portion 125 (the area enclosed by the dotted circle in the figure) can be a recessed portion recessed in the fourth surface 124, or a hollow structure penetrating along the thickness direction of the guide member 1. The second sliding portion 125 includes a fourth sliding surface 1251, a fifth sliding surface 1252, and a sixth sliding surface 1253. Among them, the fourth sliding surface 1251 can intersect with the fifth sliding surface 1252 and the sixth sliding surface 1253 respectively, and the space enclosed by the fourth sliding surface 1251, the fifth sliding surface 1252, and the sixth sliding surface 1253 is used to accommodate the transmission member 3; the fourth sliding surface 1251, the fifth sliding surface 1252, and the sixth sliding surface 1253 all extend along the direction of the transmission member 3 away from the rotating member 2 to the edge of the guide member 1, so that the transmission member 3 can move away from the transmission member 3 or move closer to the rotating member 2 during the movement.

[0069] Optionally, when the second sliding portion 125 is a hollow structure, the fifth sliding surface 1252 and the sixth sliding surface 1253 are arranged opposite to each other and spaced apart, and corresponding protrusions are formed on the fifth sliding surface 1252 and the sixth sliding surface 1253 respectively, and the protrusions extend in the direction of the transmission part 3 away from the rotating part 2, and the surface intersecting with the fifth sliding surface 1252 or the sixth sliding surface 1253 is the fourth sliding surface 1251.

[0070] Optionally, the fourth sliding surface 1251 is perpendicular to the fifth sliding surface 1252 and the sixth sliding surface 1253 .

[0071] Optionally, the fourth sliding surface 1251 is parallel to the fourth surface 124 .

[0072] As an optional implementation, Figure 9 and 10 As shown, the transmission member 3 includes a fifth surface 31 and a second transmission part 32; the second transmission part 32 is arranged to protrude from the fifth surface 31; the second transmission part 32 is arranged in the mounting part, and the second transmission part 32 is provided with a sixth surface 33, the sixth surface 33 intersects with the fifth surface 31, and the sixth surface 33 is transmission-connected to the second surface 2231.

[0073] In some possible embodiments, such as Figure 9 and 10As shown, the fifth surface 31 is a plane, the second transmission portion 32 is cylindrical, the axial direction of the second transmission portion 32 is perpendicular to the fifth surface 31, and the side surface of the second transmission portion 32 is the sixth surface 33. The transmission member 3 can be plate-shaped, and the second transmission portion 32 is disposed at one end of the transmission member 3. One end of the transmission member 3 corresponds to the mounting portion, so that the second transmission portion 32 is disposed within the mounting portion, achieving a transmission connection between the second surface 2231 and the sixth surface 33. When the transmission member 3 moves away from the rotating member 2 or toward the rotating member 2, the second surface 2231 and the sixth surface 33 slide relative to each other. Specifically, when the rotating member 2 rotates in the first direction, the second surface 2231 acts on the sixth surface 33, providing a force for the transmission member 3 to move away from the rotating member 2.

[0074] As an optional implementation, Figure 9 and 10 As shown, the first sliding portion 121 and the second sliding portion 125 are connected; the transmission member 3 is provided with a third sliding portion 34, which is connected to the second sliding portion 125; the rotating member 2 rotates along the first direction, driving the locking portion 221 to move along the first sliding portion 121 to the third sliding portion 34, and simultaneously moves along the first sliding portion 121 and the third sliding portion 34 to the locked position; the rotating member 2 rotates along the second direction, driving the locking portion 221 to move simultaneously along the third sliding portion 34 and the first sliding portion 121 to leave the locked position; the first direction and the second direction are opposite.

[0075] In some possible embodiments, such as Figure 9 and 10 As shown, the third sliding portion 34 is provided with a fifth sliding surface 35, which is a curved surface, which can be a spherical surface. The side surface of the locking portion 221 can slide along the fifth sliding surface 35, so that the locking portion 221 moves along the circumference, thereby realizing the synchronous rotation of the locking portion 221 and the rotating part 2.

[0076] When the rotating member 2 rotates in the first direction, part of the locking portion 221 moves along the first sliding portion 121 to the second sliding portion 125, and the entrance and exit of the third sliding portion 34 move with the transmission rod to a position where it is connected to the first sliding portion 121 and the second sliding portion 125, so that the first sliding portion 121 and the third sliding portion 34 are connected. The locking portion 221 moves directly to the third sliding portion 34 and simultaneously moves along the first sliding portion 121 and the third sliding portion 34, wherein the portion of the locking portion 221 away from the first surface 222 moves to the second sliding portion 125 and the third sliding portion 34. Optionally, the side of the locking portion 221 away from the first surface 222 is not connected to the third sliding portion 34 to reduce resistance to rotation.

[0077] When the rotating member 2 rotates along the first direction and drives the locking part 221 to move to the locking position, the locking part 221 contacts the guide member 1 through the first sliding part 121, and contacts the transmission member 3 through the third sliding part 34, wherein the transmission member 3 provides a force to the locking part 221 away from the moving direction of the rotating part, and the guide member 1 is stationary relative to the transmission member 3. Since the action of the force is mutual, the guide member 1 will provide a force to the locking part 221 close to the moving direction of the transmission part, so that the force of the locking part 221 on the straight line away from the moving direction of the rotating part is balanced, and the third sliding surface 123 and the fifth sliding surface 35 are curved surfaces, so that the locking part 221 is balanced in the direction of the straight line perpendicular to the moving direction of the rotating part, that is, the force is balanced in the direction parallel to the first surface 222, so that the locking part 221 is subjected to balanced force and achieves a locking effect in the locking position, so that the locking part 221 is relatively fixed relative to the transmission member 3 and the guide member 1 to achieve locking. When the rotating member 2 rotates in the second direction, it drives the locking portion 221 out of the locked position, breaking the original force balance of the locking portion 221 and achieving unlocking. Locking and unlocking through the rotation of the rotating member 2 can improve the locking ability and locking stability, and reduce the difficulty of locking and unlocking operations.

[0078] As an optional implementation method, Figure 11 As shown, the locking mechanism further includes an elastic member 5 , which is connected to the first limiting member 4 . The elastic member 5 is used to drive the first limiting member 4 to move in a direction close to the transmission member 3 , so that the transmission member 3 moves in a direction close to the rotating member 2 .

[0079] In some possible embodiments, such as Figure 9 、 10 As shown in Figures 12 and 13 , the first limiting member 4 is provided at the other end of the transmission member 3. The transmission member 3 is provided with a third transmission portion, the first limiting member 4 is provided with a fourth transmission portion for cooperating with the third transmission portion, the third transmission portion is provided with a sixth sliding surface 36, and the fourth transmission portion is provided with a seventh sliding surface 41 for cooperating with the sixth sliding surface 36. By sliding relative to each other along the sixth sliding surface 36 and the seventh sliding surface 41, the transmission member 3 and the limiting member are brought closer to or farther away from each other.

[0080] When the locking portion 221 is in the locking position, the first limiting member 4 stops moving and maintains its position unchanged, so that the transmission member 3 and the first limiting member 4 are relatively fixed; when the locking portion 221 leaves the locking position, the force that keeps the first limiting member 4 in position unchanged disappears, and under the action of the elastic member 5, the first limiting member 4 is driven to move, providing power for driving the transmission member 3 to move in the direction close to the rotating member 2.

[0081] Based on the above embodiments, Figure 13As shown, in a specific embodiment, the locking structure includes a rotating member 2, a guide member 1, two transmission members 3 and two first limit members 4. The rotating member 2 and the guide member 1 are arranged coaxially. A first transmission part 223 is provided at the center of the first surface 222 of the rotating member 2, and the first transmission part 223 includes two second surfaces 2231. The two second surfaces 2231 are identical hemispherical surfaces, and the convex parts of the two second surfaces 2231 are relatively far apart. In the direction parallel to the first surface 222, the projections of the two second surfaces 2231 do not completely overlap; the first transmission part 223 also includes two identical connecting planes 2232, wherein any connecting plane 2232 connects the two second surfaces 2231 respectively, and the two connecting planes 2232 can be located on the same plane.

[0082] The rotating member 2 is provided with two locking portions 221 , which are arranged around the first transmission portion 223 and are symmetrical with the first transmission portion 223 as a symmetry point. During the rotation of the rotating member 2 , the two locking portions 221 rotate synchronously on the same circle.

[0083] Two first sliding parts 121 are provided on the guide member 1. The two first sliding parts 121 are arranged axially around the guide member 1 and correspond to the two locking parts 221, so that the two locking parts 221 are respectively accommodated in the corresponding first sliding parts 121 and can slide along the first sliding parts 121 to achieve synchronous rotation on the same circle.

[0084] The guide member 1 is provided with two second sliding portions 125, which are connected to each other. The fifth sliding surface 1252 of one second sliding portion 125 is connected to the fifth sliding surface 1252 of the other second sliding portion 125 via a first limiting surface 126, and the sixth sliding surface 1253 of one second sliding portion 125 is connected to the sixth sliding surface 1253 of the other second sliding portion 125 via a second limiting surface 127. The first limiting surface 126 and the second limiting surface 127 are arranged in the same plane. The axial direction of the guide member 1 is located in the plane where the first limiting surface 126 and the second limiting surface 127 are located. The first limiting surface 126 and the second limiting surface 127 are both perpendicular to the fifth sliding surface 1252 and the sixth sliding surface 1253. The first limiting surface 126 and the second limiting surface 127 have the same length, which is greater than 0 and not greater than a preset length value.

[0085] The two transmission members 3 are respectively disposed in the corresponding second sliding portions 125 , so that the two second transmission portions 32 are respectively in transmission connection with the corresponding second surfaces 2231 .

[0086] Under the action of external force, the rotating member 2 rotates in the first direction, and the first rotating part 21 rotates synchronously to drive the two transmission members 3 to move in the direction away from the transmission member 3, and the movement directions of the two transmission members 3 are opposite. The moving transmission rods respectively drive the corresponding first limiting members 4 to move in the direction away from the transmission rod until the locking part 221 reaches the locking position.

[0087] Under the action of external force, the rotating member 2 rotates in the second direction, driving the locking portion 221 to leave the locking position, leaving space for the transmission member 3 to move in the direction close to the transmission member 3; under the action of the spring, the first limiting member 4 is driven to move in the direction close to the transmission rod, driving the two transmission members 3 to move in the direction close to the transmission member 3 respectively.

[0088] Based on the same inventive concept, the embodiment of the present application provides a steamer, such as Figure 14 As shown, it mainly includes a first door member 7 and a second door member 8. The first door member 7 is provided with a second limit member 9; the second door member 8 is provided with a locking mechanism according to any of the aforementioned embodiments of the present application, which is used to move the first limit member 4 to the second limit member 9 so that the first limit member 4 and the second limit member 9 are relatively fixed, thereby achieving locking of the first door member 7 and the second door member 8.

[0089] In some possible embodiments, one side of the first door member 7 and one side of the second door member 8 are rotatably connected. The relative rotation of the first door member 7 and the second door member 8 enables the first door member 7 and the second door member 8 to be opened or closed, further enabling the steamer to be opened or closed. A second stopper 9 is disposed on a side of the first door member 7 away from the rotational connection, and a locking mechanism is disposed on a side of the second door member 8 away from the rotational connection. When the first door member 7 and the second door member 8 are closed, the second stopper 9 is located on a path of movement of the first stopper 4 away from the transmission member 3. By rotating the rotating member 2 of the locking mechanism, the transmission member 3 is driven to move. The moving transmission member 3 drives the first stopper 4 to move in a direction away from the transmission member 3 and to the second stopper 9, thereby enabling the first stopper 4 and the second stopper 9 to interact with each other and generate interference.

[0090] When the locking structure is in the locked state, the first limiting member 4 and the second limiting member 9 are relatively fixed to lock the first door member 7 and the second door member 8. When the locking structure is in the unlocked state, the elastic member 5 drives the first limiting member 4 away from the second limiting member 9 to unlock the first door member 7 and the second door member 8.

[0091] In the steamer provided in the embodiment of the present application, when the locking structure is in the locked state, the positions of the first limit member 4 and the second limit member are relatively fixed, and the direction of opening the first door member 7 and the second door member 8 intersects with the direction in which the first limit member 4 moves away from the transmission member 3. When the pressure in the steamer pushes the first door member 7 outward, the first limit member 4 and the second limit member 9 interfere with each other, preventing the first door member 7 and the second door member 8 from opening, thereby ensuring the stability of the locking of the first door member 7 and the second door member 8.

[0092] Optionally, the first door member 7 may be a front frame of the inner container;

[0093] Optionally, the second door member 8 may be a door body.

[0094] Optionally, the second limiting member 9 is a limiting ring, and when the first limiting member 4 moves to the target position, the second limiting member 9 is sleeved on the first limiting member 4 .

[0095] As an optional implementation, Figure 15 As shown, the locking mechanism further includes a handle 6 , which is connected to the rotating member 2 of the locking mechanism and is used to drive the rotating member 2 to rotate.

[0096] In some possible embodiments, such as Figure 15 As shown, a first connecting portion 224 is provided on the side of the rotating member 2 away from the guide member 1, and a second connecting portion 621 is provided at one end of the handle 6 to cooperate with the first connecting portion 224 to achieve a rotational connection between the handle 6 and the locking mechanism.

[0097] As an optional implementation, Figure 15 and 16 As shown, the handle 6 includes a handle base 61 and a motor 62 ; the handle base 61 is sleeved with the motor 62 , and the output end of the motor 62 is used for driving connection with the rotating member 2 .

[0098] In some possible embodiments, such as Figure 15 and 16 As shown, the handle 6 includes a handle body 63, a handle base 61 connected to the handle body 63, and a motor 16 located in the handle base 61. The output end of the motor 62 includes the aforementioned second connecting portion 621, and the motor 62 drives the rotating member 2 to rotate in the first direction or the second direction.

[0099] By applying the embodiments of this application, at least the following beneficial effects can be achieved:

[0100] The locking structure provided in the embodiment of the present application is that the rotating member 2 rotates along the first direction, driving the transmission member 3 to move in a direction away from the rotating member 2, so that the moving transmission member 3 drives the first limit member to move in a direction away from the transmission member 3, and the rotating member 2 synchronously drives the locking part 221 to move along the first sliding part 121 to the locking position. When the locking part 221 reaches the locking position, the locking part 221 is balanced in force and stops rotating, so that the positions of the rotating member 2 and the guide member 1 are relatively fixed, achieving locking. At the same time, the first limit member stops moving, and the positions of the first limit member and the transmission member 3 are relatively fixed; the rotating member 2 rotates in a second direction opposite to the first direction, breaking the force balance of the locking part 221, and driving the locking part 221 away from the locking position to achieve unlocking.

[0101] In the steamer provided in the embodiment of the present application, when the locking structure is in the locked state, the positions of the first limit member 4 and the second limit member are relatively fixed, and the direction of opening the first door member 7 and the second door member 8 intersects with the direction in which the first limit member 4 moves away from the transmission member 3. When the pressure in the steamer pushes the first door member 7 outward, the first limit member 4 and the second limit member 9 interfere with each other, preventing the first door member 7 and the second door member 8 from opening, thereby ensuring the stability of the locking of the first door member 7 and the second door member 8.
