The cover 250 may form an output terminal base 61, the cover 250 is detachably inserted into the input terminal base 20, and the output conductive part 62 is electrically connected to the input conductive part 40, so as to couple the input terminal 10 and the output terminal 60, so that the ultrasonic transducer device 220 is detachably connected to the cover body 210.

For example, in some embodiments, the cooking appliance 300 implements power transmission through the power coupler 100, wherein the input terminal part 10 is mounted on the upper cover of the cover body 210, and the output terminal part 60 is mounted on the cover plate of the cover body 210. When the cover plate needs to be cleaned, the input end part 10 is separated from the output end part 60, so that the cover plate can be detached, the cover plate is more convenient to clean, and the risk of short circuit or electric shock caused by water inflow of the input end part 10 is avoided.

As shown in fig. 12 to 14, a groove 201 may be provided in the input terminal base 20, so that the input terminal base 20 is formed as a cup, and as shown in fig. 18, the input conductive portion 40 is connected to the input terminal base 20, and the input conductive portion 40 is exposed from an inner wall surface of the groove 201. The output terminal member 60 has an output conductive portion 62. When the input terminal 10 and the output terminal 60 are connected, the output conductive part 62 may extend into the groove 201 to connect with the input conductive part 40, so as to transmit power from the input terminal 10 to the output terminal 60. When the input terminal part 10 and the output terminal part 60 are separated, the output conductive part 62 moves out of the groove 201. The input conductive part 40 is positioned in the groove 201, so that a user is not easy to contact with the input conductive part 40, and the risk of electric shock is reduced.

Alternatively, as shown in fig. 29, the input conductive part 40 may be an electrode terminal, the inner wall of the input terminal base 20 may be provided with a mounting slot 203, a part of the electrode terminal may be clamped into the mounting slot 203, and another part of the electrode terminal may extend from the mounting slot 203 and into the groove 201 so as to be connected to the output conductive part 62.

In addition, in the present invention, the power coupler 100 further includes a cover 30 and a self-locking structure 50. Wherein the cover 30 may be provided to the input base 20 and the cover 30 may be movable between a closed position and an open position. As shown in fig. 12 and 13, when the cover 30 is in the closed position, the notch of the groove 201 can be covered to prevent the user from extending into the groove 201 to contact the input conductive part 40 when the input terminal part 10 is separated from the output terminal part 60, thereby further reducing the risk of electric shock. As shown in fig. 14, when the cover 30 is in the open position, the notch of the groove 201 can be opened, so that the output conductive part 62 can extend into the groove 201 to be connected with the input conductive part 40, and the power coupler 100 can be used normally.

In addition, as shown with continued reference to fig. 12-14, the self-locking mechanism 50 is connected to the input base 20, and the self-locking mechanism 50 can be switched between a locked state and an unlocked state. As shown in fig. 12 and 13, the self-locking mechanism 50 can limit the movement of the cover 30 to the open position when in the locked state, and as shown in fig. 14, the self-locking mechanism 50 can release the limitation of the cover 30 when in the unlocked state.

Therefore, when the input end component 10 and the output end component 60 are separated, the output conductive part 62 moves out of the groove 201, the cover 30 is located at the closed position, and the self-locking structure 50 moves to the locking state, so that the cover 30 is prevented from being pushed by a user to extend into the groove 201 to cause electric shock accidents. When the input terminal 10 and the output terminal 60 are connected, the self-locking structure 50 is in an unlocked state, the cover 30 can be moved to an open position, the output conductive part 62 can extend into the groove 201 to be connected with the input conductive part 40, and the connection position of the input conductive part 40 and the output conductive part 62 is located in the groove 201, so that a user can be prevented from touching and getting an electric shock.

It should be noted that, in the present invention, the number of the self-locking structures 50 can be adjusted according to actual requirements. In the specific embodiment shown in fig. 12-14, the power coupler 100 includes two self-locking structures 50 for illustrative purposes, but it is obvious to those skilled in the art after reading the technical solution of the present invention that the solution can be applied to one, three or more self-locking structures 50, and this also falls into the protection scope of the present invention.

It should be noted that, in the process of assembling and disassembling the output terminal component 60 and the input terminal component 10, the self-locking structure 50 can automatically implement state switching or manually implement state switching by a user, so as to meet different application requirements. In some embodiments, the self-locking mechanism 50 may automatically switch to the locking state when the output terminal part 60 is separated from the input terminal part 10, and the self-locking mechanism 50 may move to the unlocking state under the pushing of the output terminal part 60 during the connection of the output terminal part 60 with the input terminal part 10. Therefore, the state switching of the self-locking structure 50 can be realized without additional operation of a user, the situation that the input end part 10 is not self-locked due to forgetting operation of the user is prevented, the operation steps of the output end part 60 and the input end part 10 during installation are reduced, and the installation is more convenient.

In some embodiments of the present invention, as shown in fig. 12, the self-locking structure 50 may include: a stopper 51 and a driver 52. Wherein the stop member 51 is connected to the input base 20 and the stop member 51 is movable between a first position as shown in fig. 12 and 13 and a second position as shown in fig. 14. When the stopper 51 is located at the first position, the stopper 51 can stop the cover 30 from moving to the open position, so that the cover 30 is kept in the state of covering the notch of the groove 201 and is always located at the closed position. When the stopper 51 is located at the second position, the stopper 51 releases the stopper of the cover 30, so that the cover 30 can move into the groove 201. In addition, the stop member 51 is usually in the first position, that is, the stop member 51 usually stops the cover 30, so that the cover 30 cannot move to the open position, and the notch of the groove 201 is usually in the cover sealing state, so that the electric shock protection effect is better.

The driving member 52 can be connected to the input end base 20, and when the output end member 60 is inserted into the input end member 10, the driving member 52 can move under the pushing of the output end member 60, and the driving member 52 drives the stopper 51 to move to the second position. The driving member 52 can convert the mounting action of the output end member 60 into the movement of the stop member 51 to the second position, and the structure is reasonable.

For example, in the embodiment shown in fig. 12-14, when the output end member 60 is inserted into the input end member 10, the output end member 60 pushes the driving member 52 to rotate the driving member 52 relative to the input end base 20, and during the rotation of the driving member 52 from the position shown in fig. 12 to the position shown in fig. 13, the driving member presses the stopper 51 to rotate the stopper 51 relative to the input end base 20, so that the stopper 51 releases the limitation of the cover 30.

It should be noted that, for easy understanding, the positions of the driving members 52 are shown in the positions illustrated in fig. 12, and the positions of the stoppers 51 in the first position and the second position are shown, but two driving members 52 are not provided in one position.

According to a further embodiment of the present invention, as shown in fig. 12 and 13, the stopper 51 may be rotatably coupled to the input terminal base 20, the self-locking structure 50 may further include a stopper returning member 53, the stopper returning member 53 may be coupled to the input terminal base 20, and the stopper returning member 53 may apply a force to the stopper 51 to move the stopper 51 toward the first position. That is, the stop return member 53 can normally drive the stop member 51 to the first position, thereby achieving the self-locking of the input member 10.

Further, as shown in fig. 15 to 17, the stopper 51 may include: a connecting portion 511, a stopper portion 512, and a drive fitting portion 513. As shown in fig. 12 and 18, the stopping portion 512 and the driving fitting portion 513 are respectively connected to the connecting portion 511, the stopping portion 512 can stop the cover 30, the driving fitting portion 513 can be fitted to the driving member 52, and the connecting portion 511 is rotatably connected to the input terminal base 20. Therefore, the driving member 52 moves to drive the driving matching portion 513 to move, and the driving matching portion 513 moves to drive the connecting portion 511 to rotate relative to the input terminal base 20, so as to drive the stopping portion 512 to rotate relative to the input terminal base 20, so as to realize stopping and stopping release of the stopping portion 512 and the cover 30.

According to some embodiments of the present invention, as shown in fig. 12 and 23, the stopper restoring member 53 may be a torsion spring, as shown in fig. 27 to 29, the input terminal base 20 may be provided with the rotation shaft 21, and the connection portion 511 may be provided with the first limit groove 5111 and the drum 5112. The drum 5112 can be sleeved on the rotating shaft 21 to rotate, so that the stopper 51 is not easily deviated or dropped when rotating relative to the input end base 20, and the rotation is smoother. As shown in fig. 18, the coil of the torsion spring can be sleeved on the drum 5112, one end of the torsion spring is connected to the input end base 20, and the other end of the torsion spring can be disposed in the first limiting groove 5111, so that the torsion spring is firmly and reliably fixed and is not easy to loosen.

Of course, in other embodiments, the positions of the rotating shaft 21 and the rotating drum 5112 can be interchanged, that is, the input end base 20 can be provided with the rotating drum 5112, and the connecting portion 511 can be provided with the rotating shaft 21, which can also realize the rotatable connection of the stopper 51 and the input end base 20.

In addition, it should be noted that the connection structure of one end of the torsion spring and the input terminal base 20 is not particularly limited. For example, the input terminal base 20 may have a fixing hole or a fixing groove, and one end of the torsion spring may extend into the fixing hole or the fixing groove, so that the one end of the torsion spring is more reliably fixed to the input terminal base 20. For another example, one end of the torsion spring may abut against the inner wall surface of the input end base 20, which may also provide support for the torsion spring when the other end of the torsion spring is pressed by the stopper 51, so that the torsion spring may apply an acting force to the stopper 51.

Further, as shown in fig. 27 to 29, there are two rotating shafts 21, a fixed end of each rotating shaft 21 is connected to the input terminal base 20, there are two rotating cylinders 5112, two rotating cylinders 5112 are respectively provided at both ends of the rotation axis of the stopper 51, and the rotating shafts 21 are engaged into the rotating cylinders 5112 in a one-to-one correspondence. When the stopper 51 is mounted to the input terminal base 20, the drum 5112 is inserted in the radial direction of the rotary shaft 21 until the rotary shaft 21 is caught in the drum 5112. At least a part of the end surface of the free end of the rotating shaft 21 is formed as an inclined surface which extends obliquely in the direction approaching the other rotating shaft 21 toward downward in the insertion direction of the drum 5112. The inclined surface can guide the drum 5112 when the drum 5112 is inserted in the radial direction of the rotating shaft 21, making the installation of the stopper 51 simpler and more labor-saving.

Alternatively, the first limit groove 5111 may be disposed on the stopping portion 512 or the driving fitting portion 513. For example, in the specific embodiment shown in fig. 15 to 17, the stopping portion 512 includes two stopping portions provided at both axial ends of the stopping member 51, the driving fitting portion 513 is provided at a middle portion of the stopping member 51, and a dimension of a free end of the driving fitting portion 513 in the axial direction of the stopping member 51 is smaller than a dimension of a fixed end of the driving fitting portion 513 in the axial direction of the stopping member 51. One side that backs each other of two backstop portions 512 is formed with the flanging, and the flanging limits first spacing groove 5111 with backstop portion 512 jointly, and when two torsional springs inserted two first spacing grooves 5111 respectively, can act on backstop portion 51 from backstop portion 51's axial both ends, and backstop portion 51 atress is more even to driving piece 52 all does not take place to interfere with drive cooperation portion 513's cooperation, torsional spring, backstop portion 512 and closing cap 30's cooperation, and structural design is more reasonable.

In some embodiments of the present invention, as shown in fig. 12, 14, 20 and 21, the outer peripheral surface of the cover 30 may be provided with a stopper mesa 301. When the stopper 51 is in the first position, the stopper 51 may interfere with the stop platform 301 to stop the cover 30 from moving to the open position, and when the stopper 51 is in the second position, the stopper 51 may move outward to avoid the stop platform 301.

For example, in the example shown in fig. 12 and 14 in which the stopper 51 includes the stopper portion 512, the cover 30 moves upward to realize the movement from the first position to the second position, as shown in fig. 12, the limiting table 301 is a step formed on the outer peripheral surface of the cover 30, and when the stopper 51 is located at the first position, the free end of the stopper portion 512 may abut against the upper surface of the step or be spaced apart by a small distance, so that the cover 30 cannot move into the groove 201 to expose the output conductive portion 40. As shown in fig. 14, when the stopper 51 is located at the second position, the stopper 512 rotates with the stopper 51, the free end of the stopper 512 moves in the radial direction of the cap 30 in the direction away from the axis of the cap 30, so that the free end of the stopper 512 is located outside the stepped terrace, the stopper function of the stepped terrace is released, and the cap 30 can move upward.

Further, as shown in fig. 14-17, the stop member 51 may further have a limiting rib 514, and when the cover 30 is not installed on the input end base 20, the limiting rib 514 may abut against the input end base 20 to limit the inward rotation angle of the stop member 51 and prevent interference with the stop member 51 when the cover 30 is installed. When the input end base 20 is mounted with the cover 30, the inward rotation angle of the stop member 51 can be limited by the limit rib 514 abutting against the input end base 20, and can also be limited by the stop member 51 abutting against the cover 30, which are within the protection scope of the present invention.

According to some embodiments of the present invention, as shown in fig. 12-14, the driving member 52 is rotatably connected to the input terminal base 20, the self-locking mechanism 50 may further include a driving reset member 54, the driving reset member 54 may be connected to the input terminal base 20, and the driving reset member 54 may apply a reset force to the driving member 52 to reset the driving member 52 to the initial position. Thus, when the output end member 60 is separated from the input end member 10, the driving member 52 can automatically rotate to the initial position shown in fig. 12 under the action of the reset force of the reset member 54, so that the driving member 52 releases the driving action on the stop member 51, and the stop member 51 can move to the first position to limit the movement of the cover 30. When the output member 60 is inserted into the input member 10, the output member 60 compresses the drive return 54 against the return force of the drive return 54 to rotate the driver 52.

Further, as shown in fig. 22-24, the driving member 52 may include: drive connecting portion 521, drive portion 522 and spacing cooperation portion 523. The driving part 522 may be connected to the driving connection part 521, the driving part 522 may drive the stopper 51 to rotate, and the driving connection part 521 may be rotatably connected to the input terminal base 20. Thus, when the driving member 52 rotates relative to the input end base 20, the driving portion 522 can be driven to rotate to engage and disengage with the stop member 51.

In addition, as shown in fig. 22 to 24, the limit fitting part 523 may be connected to the driving connection part 521, and as shown in fig. 25 and 26, the input terminal base 20 may be provided with the limit part 26. When the output end member 60 is separated from the input end member 10, under the reset force of the reset element 54, the limit engaging portion 523 can abut against the limit portion 26 to limit the driving element 52 and prevent the driving element 52 from disengaging from the input end base 20.

According to a further embodiment of the present invention, as shown in fig. 22-28, the driving restoring element 54 may be a torsion spring, the input end base 20 may be provided with a shaft groove 221, the limit fitting portion 523 may be provided with a second limit groove 5231, the driving connecting portion 521 may be provided with a shaft rod 5211, the shaft rod 5211 may be disposed in the shaft groove 221, and the shaft rod 5211 may rotate in the shaft groove 221, so that the driving element 52 is not easily deviated or falls off when rotating relative to the input end base 20, and the rotation is smoother. As shown in fig. 26, the coil of the torsion spring may be sleeved on the shaft rod 5211, one end of the torsion spring may be connected to the input terminal base 20, and the other end of the torsion spring may be disposed in the second limiting groove 5231, so that the torsion spring is firmly and reliably fixed and is not easily loosened.

Further, as shown in fig. 27, the bottom wall of the input end base 20 may be provided with an installation opening 202, the driving element 52 may be disposed at the installation opening 202, the edge of the installation opening 202 may be provided with an installation seat 22, and the axial groove 221 may be disposed in the installation seat 22, so that the installation seat 22 may support the driving element 52 by the two axial ends of the driving element 52, and the driving element 52 is stressed more uniformly and rotates more smoothly. The position-limiting portion 26 can be a buckle connected to the mounting seat 22 and extending inward, where "inward" refers to a direction toward the mounting opening 202, so that when the driving member 52 rotates under the action of the restoring force of the torsion spring, an inner end of the buckle can abut against the position-limiting engaging portion 523 to prevent the driving member 52 from rotating out of the mounting opening 202.

According to some embodiments of the present invention, as shown in fig. 26, the shaft 5211 may be provided with a blocking rib 5212, and the blocking rib 5212 may limit the torsion spring in the axial direction of the shaft 5211, so as to prevent the torsion spring from being displaced too much in the axial direction of the shaft 5211, so as to affect the restoring force.

In some embodiments of the present invention, as shown in fig. 22 and 24, the driving part 522 may be connected to the middle of the shaft 5211, so that the driving member 52 is uniformly stressed, and the force of the driving member 52 on the stopper 51 is more stable. In addition, the middle part of the shaft lever 5211 can be further provided with a stop rib 524, and when the driving member 52 rotates under the action of the restoring force of the torsion spring, the stop rib 524 can abut against the bottom wall surface of the input end base 20 to limit the driving member 52, so as to prevent the driving member 52 from rotating at an excessively large angle and being disengaged from the input end base 20. The position-stopping ribs 524 and the driving part 522 can be distributed along the circumferential direction of the shaft rod 5211, the stress uniformity of the driving part 52 can be further heightened, the interference of the structures of the position-stopping ribs 524 and the driving part 522 can be prevented, and the structural design is reasonable.

Alternatively, the power coupler 100 may include only the limiting portion 26 and the limiting engagement portion 523, only the stopping rib 524, or both the limiting portion 26, the limiting engagement portion 523 and the stopping rib 524, which may limit the rotation angle of the driving member 52.

The resilient member 55 may return the cover 30 to the closed position, i.e., the resilient member 55 may normally urge the cover 30 to cover the notch of the recess 201. When the output end part 60 is separated from the input end part 10, the elastic member 55 can drive the cover 30 to automatically move to the closed position, so that manual operation is not required, and the use is more convenient.

Alternatively, as shown in fig. 12 and 14, the bottom wall surface of the groove 201 may be provided with a positioning post 251 protruding into the groove 201, as shown in fig. 20, the sealing cap 30 may have an inner cylinder 32 and an outer cylinder 33 coaxially disposed, one end of the elastic member 55 may be sleeved on the positioning post 251, the other end of the elastic member 55 may be inserted into the inner cylinder 32, and the inner cylinder 32 and the positioning post 251 may limit the radial position of the elastic member 55, so as to prevent the elastic member 55 from radially distorting or displacing to affect the driving action on the sealing cap 30.

In addition, as shown in fig. 20, the outer peripheral surface of the sealing cover 30 may be provided with a hook 31 protruding outward, when the sealing cover 30 is in the closed position, the hook 31 may be clamped at the edge of the notch of the groove 201 to limit the sealing cover 30, so as to prevent the sealing cover 30 from coming out of the notch of the groove 201, and the sealing cover 30 is more reliably fixed.

Further, as shown in fig. 18 and 29, the inner wall surface of the input terminal base 20 may be provided with a guide post 23, the hook 31 may have a guide groove 311, and the guide post 23 may be engaged with the guide groove 311 to move so as to guide the movement of the cover 30, thereby preventing the cover 30 from being tilted and locked, and making the movement of the cover 30 smoother.

Alternatively, as shown in fig. 12, 29 and 30, the input terminal base 20 may include a housing 24 and a top cover 25, the top cover 25 may be provided on one axial end of the housing 24 to define the groove 201 together with the housing 24, an inner surface of the top cover 25 is formed as a bottom wall surface of the groove 201, the positioning column 251 may be provided on the top cover 25, and the other axial end of the housing 24 may be formed as a notch of the groove 201. The input conductive part 40, the stopper 51 and other structures can be installed in the shell 24 from one axial end of the shell 24 when the top cover 25 is not installed on the shell 24, so that the installation is more convenient and the operation is easy.

In addition, the top cover 25 may have an opening, as shown in fig. 12, 14 and 19, and the input conductive part 40 may protrude from the opening out of the groove 201 to be connected with the power input lead, or the power input lead may protrude from the opening into the groove 201 to be connected with the input conductive part 40.

In some embodiments of the present invention, as shown in fig. 31-33, the output end member 60 may include an output end base 61, and the output end base 61 may include a base main body 611 and a protrusion 612, and the protrusion 612 is convexly disposed on one side of the base main body 611, so that the output end base 61 is formed into a convex structure, which is not easy to generate a dead angle and avoids the accumulation of residues. The convex part 612 can extend into the groove 201 to realize the connection of the input end part 60 and the input end part 10, and the connection mode is simple and easy to disassemble and assemble.

With continued reference to fig. 31-33, the output conductive portion 62 may be connected to the output terminal base 61, and the output conductive portion 62 may be exposed from the outer circumferential surface of the convex portion 612, so that the output conductive portion 62 may extend into the groove 201 along with the convex portion 612 to be connected to the input conductive portion 40. In addition, when the convex portion 612 extends into the groove 201, the convex portion 612 can drive the self-locking structure 50 to move, so that the self-locking structure 50 is switched to an unlocking state, unlocking and installation are performed simultaneously, operation steps are fewer, and installation is more convenient.

Further, as shown in fig. 31 and 32, the outer peripheral surface of the convex portion 612 may be provided with a rib 613, the rib 613 extending in the axial direction of the convex portion 612. The rib 613 can drive the self-locking mechanism 50 to move during the process of the protrusion 612 extending into the groove 201. In the embodiment where the bottom wall of the input terminal base 20 has the mounting opening 202, the rib 613 may be fitted in the mounting opening 202, and the mounting opening 202 may limit the circumferential direction of the protrusion 612, so as to prevent the protrusion 612 from rotating freely, and thus, the input conductive part 40 and the output conductive part 62 are aligned more accurately.

Alternatively, as shown in fig. 32, the protrusion height L of the rib 613 from the outer peripheral surface of the convex portion 612 may satisfy: 0mm < L.ltoreq.3 mm, for example, in some embodiments, the protrusion heights L of the ribs 613 protruding from the outer peripheral surface of the convex portion 612 may be 1mm, 1.5mm, 2mm, 2.5mm, and the like. L is more than 0mm, so that the rib 613 and the self-locking structure 50 are more conveniently and accurately aligned, and L is less than or equal to 3mm, so that the radial dimension of the power coupler 100 can be prevented from being too large, and the structure is more compact.

According to some embodiments of the present invention, as shown in fig. 32, the rib 613 exceeds the end surface of the end of the protrusion 612 far away from the base main body 611, so that the rib 613 is aligned with the self-locking structure 50 more conveniently and accurately, and the exceeding distance H can satisfy: 1mm < H.ltoreq.6 mm, for example, in some embodiments the excess distance H may be 2mm, 3mm, 4mm, 5mm, etc., respectively. H is less than or equal to 6mm, so that the axial length of the power coupler 100 can be prevented from being overlong, and the structure is more compact. Further, the excess distance H may satisfy: h is more than or equal to 2mm and less than or equal to 4 mm.
