The power coupler 20, the ultrasonic vibrator assembly, the upper cover assembly 100 and the cooking appliance 200 according to the embodiment of the present invention are described below with reference to the accompanying drawings.

Referring to fig. 1, 3, 5 and 6, a power coupler 20 according to an embodiment of the present invention may include: input end member 30 the input end member 30 may comprise: an input terminal base 31, a cover 32, and an input conductive portion 33.

Optionally, in some embodiments, the power coupler 20 may further include an output terminal part 40, the output terminal part 40 has an output conductive part 42, and the input terminal part 30 and the output terminal part 40 may be detachably coupled, so that the power coupler 20 may be separated from the output terminal part 40 through the input terminal part 30 during use, thereby realizing the detachable connection between different parts of the cooking appliance 200, and facilitating use. Of course, in some embodiments, the power coupler 20 may not be provided with the output terminal part 40, for example, the input terminal part 20 may be directly electrically connected to the electric part such as the ultrasonic vibrator 60 of the cooking appliance 200, or indirectly electrically connected to the electric part through other parts.

Taking the power coupler 20 including the input terminal part 30 and the output terminal part 40 as an example, in some embodiments, the cooking appliance 200 performs power transmission through the power coupler 20, wherein the input terminal part 30 is mounted on the upper cover of the upper cover body 10 of the cooking appliance 200, and the output terminal part 40 is mounted on the cover plate 12 of the upper cover body 10. When the cover plate 12 needs to be cleaned, the input end part 30 is separated from the output end part 40, so that the cover plate 12 can be detached, the cover plate 12 is more convenient to clean, and the risk of short circuit or electric shock caused by water entering the input end part 30 is avoided. In other embodiments, input end member 30 is mounted to the base of pan body assembly 210 of cooking appliance 200 and output end member 40 is mounted to the inner pan of pan body assembly 210. The input end component 30 and the output end component 40 are separated, so that the inner pot can be taken out from the base, and the food taking and placing and the inner pot cleaning are more convenient.

As shown in fig. 1-5, a groove 311 may be formed in the input terminal base 31, such that the input terminal base 31 is formed as a cup, and the input conductive part 33 is disposed on the input terminal base 31 to connect with an external power source. When the input terminal 30 and the output terminal 40 are connected, the output conductive part 42 may extend into the recess 311 to be electrically connected with the input conductive part 33, so as to realize the power transmission from the input terminal 30 to the output terminal 40. When the input terminal member 30 and the output terminal member 40 are separated, the output conductive portion 42 moves out of the recess 311. The input conductive part 33 is located in the groove 311, so that a user is not easy to contact with the input conductive part 33, and the risk of electric shock is reduced. The connection and disconnection of the output conductive part 42 and the input conductive part 33 can be realized by inserting the output terminal part 40 into the groove 311 and pulling out the groove 311, and the operation process is simpler.

In addition, in the present invention, the power coupler 20 further includes a cover 32, the cover 32 may be disposed on the input base 31, and the cover 32 may be movable between the closed position and the open position along the axial direction of the groove 311. As shown in fig. 1-4 and 7, when the cover 32 is located at the closed position, the cover 32 can cover the notch of the recess 311, so as to prevent the user from extending into the recess 311 to contact the input conductive portion 33 when the input end member 30 is separated from the output end member 40, thereby further reducing the risk of electric shock, and the cover 32 can shield external liquid and the like, thereby effectively reducing the risk of liquid entering the recess 311 to contact the input conductive portion 33. As shown in fig. 5, when the cover 32 is pushed by the output terminal member 40 to move to the open position, the notch of the recess 311 may be opened, so that the output conductive portion 42 may extend into the recess 311 to be electrically connected to the input conductive portion 33, and the power coupler 20 may be used normally.

In addition, because the power coupler 20 is generally used in places with high humidity in the working environment, such as a kitchen, and a certain amount of steam, oil smoke, or dust is generated during the operation of the cooking devices in the kitchen, when the input end member 30 is not used for supplying power, for example, when the input end member 30 is separated from the output end member 40, if impurities, such as external liquid, steam, oil smoke, or dust, enter the groove 311 through the gap between the sealing cover 32 and the input end base 31, the impurities may contact the input conductive part 33, causing a short circuit of the electrical connection structure of the input end member 30, and causing the power coupler 20 to be unable to transmit power, which is serious, even may cause a situation of electric shock of a user or cause a fire, and seriously affects the service life and safety performance of the power coupler 20.

Therefore, in the present invention, as shown in fig. 2 and 4, the notch edge of the groove 311 is provided with the sealing portion 312, the sealing portion 312 extends along the circumferential direction of the notch edge, the cover 32 has the seal fitting portion 321, and the seal fitting portion 321 extends along the circumferential direction of the cover 32. When the input and output end members 30 and 40 are separated and the cover 32 is in the closed position, the sealing portion 312 may engage with the seal engaging portion 321 to seal the gap between the notch edge and the cover 32. From this, can prevent that liquid, steam, oil smoke, dust etc. from getting into input part 30 inside through the clearance between notch border and the closing cap 32, and then not only can make power coupler 20 can normally work, improve power coupler 20's life, can prevent to take place electric shock accident or fire incident moreover, power coupler 20 uses safelyr.

In some embodiments, as shown in fig. 8-11, the sealing engagement portion 321 may be a sealing rib, as shown in fig. 12-14, and the sealing portion 312 may be a sealing surface, as shown in fig. 2 and 4, and the sealing rib may abut against the sealing surface when the lid 32 is in the closed position, so as to achieve sealing between the lid 32 and the edge of the notch, and the sealing structure is simple and has good sealing effect.

Of course, in other embodiments, the arrangement positions of the sealing rib and the sealing surface may be interchanged, specifically, the sealing engagement portion 321 may be the sealing surface, and the sealing portion 312 may be the sealing rib, which may also achieve sealing by the sealing rib abutting against the sealing surface. In other words, one of the sealing portion 312 and the seal-fitting portion 321 is a sealing surface, and the other of the sealing portion 312 and the seal-fitting portion 321 is a sealing bead which can abut against the sealing surface.

Further, as shown in fig. 12 and 14, the sealing surface may be an annular flat surface extending perpendicular to the moving direction of the cap 32. From this, when closing cap 32 moves to the closed position, the sealed extending direction of the sealed face of effort perpendicular to between sealed face and the sealed protruding muscle, sealed face and the sealed protruding muscle between effort extend along closing cap 32's moving direction promptly, make closing cap 32's circumference go up atress everywhere more even, and closing cap 32 is difficult for taking place the slope, and sealed effect is better between closing cap 32 and the notch border.

Alternatively, as shown in fig. 4 and 8, the axial section of the seal bead may be formed in a semicircular shape, and the arc-shaped surface of the seal bead may abut against the seal surface. The simple structure of sealed protruding muscle, easily machine-shaping is favorable to reducing machining error to improve sealed effect, and semi-circular structure makes sealed protruding muscle have self sealss effect, and the in-process that the closing cap 32 removed repeatedly between closed position and the open position, sealed protruding muscle is difficult for wearing and tearing to be out of shape, is favorable to improving the life of sealed protruding muscle.

It should be noted that the term "semicircular" herein includes, but is not limited to, the exact semicircular shape shown in fig. 4 and 8, and may also refer to a large semicircular shape or a small semicircular shape, which is within the scope of the present invention.

According to some embodiments of the present invention, as shown in fig. 8-10, the outer circumferential surface of the cover 32 may be formed with a step surface 322, the step surface 322 including: a first peripheral surface 323, a second peripheral surface 324, and an annular land 325, wherein the first peripheral surface 323 and the second peripheral surface 324 extend in the circumferential direction of the lid 32, and the first peripheral surface 323 is larger in radial dimension than the second peripheral surface 324, the annular land 325 being connected between the first peripheral surface 323 and the second peripheral surface 324.

As shown in fig. 8 and 10, the seal-fitting portion 321 is provided on the annular table 325 so as to project in a direction away from the first peripheral surface 323. As shown in fig. 2 and 4, when the cover 32 is in the closed position, the first circumferential surface 323 may be located in the groove 311, and the sealing portion 312 may surround the second circumferential surface 324 and abut against one axial end of the sealing engagement portion 321. From this, sealed cooperation portion 321 cooperates with sealing portion 312, not only can seal the clearance between closing cap 32 and the notch border, can also carry on spacingly to closing cap 32, prevents that closing cap 32 from deviating from by the notch of recess 311, and closing cap 32 is fixed more reliably.

In some embodiments of the present invention, as shown in fig. 12 and 14, the inner wall surface of the notch end of the groove 311 may further include a positioning surface 313, the positioning surface 313 is disposed between the sealing portion 312 and the inner peripheral wall surface of the groove 311, and a distance between the sealing portion 312 and the bottom wall of the groove 311 (i.e., the upper groove wall surface of the groove 311) is greater than a distance between the positioning surface 313 and the bottom wall of the groove 311, so that a step structure is formed between the positioning surface 313 and the sealing portion 312.

As shown in fig. 12, the inner peripheral wall surface of the recess 311 may be provided with a guide rib 314, and the guide rib 314 extends to the positioning surface 313 in the axial direction of the recess 311. As shown in fig. 9 to 11, the outer peripheral surface of the cover 32 may be provided with a positioning projection 326 projecting outward, the positioning projection 326 may have a positioning groove 327, the seal-fitting portion 321 may be provided on the outer peripheral surface of the cover 32, and the seal-fitting portion 321 is located on the side of the positioning projection 326 close to the notch of the groove 311.

The positioning groove 327 can be movably engaged with the guiding rib 314 to guide and limit the movement of the cover 32, so as to prevent the cover 32 from being tilted and jammed, and the cover 32 can move more smoothly. When the sealing cover 32 is in the closed position, the positioning convex part 326 can abut against the positioning surface 313, and the sealing part 312 abuts against the sealing matching part 321, so that the effect of preventing the sealing cover 32 from being disengaged from the groove 311 is better, and the radial position of the sealing cover 32 can be limited due to the step structure formed between the positioning surface 313 and the sealing part 312, and the sealing effect is prevented from being influenced due to the deviation of the sealing cover 32.

According to some embodiments of the present invention, as shown in fig. 1 to 5, an elastic member 38 may be disposed between the cover 32 and the bottom wall surface of the groove 311, and the cover 32 and the bottom wall surface of the groove 311 may axially position the elastic member 38. The elastic member 38 can return the cover 32 to the closed position, that is, the elastic member 38 can always drive the cover 32 to cover the notch of the sealing groove 311. When the output terminal part 40 is separated from the input terminal part 30, the elastic part 38 can drive the cover 32 to automatically move to the closed position, manual operation is not needed, and the use is more convenient. And the elastic member 38 may increase the force between the sealing portion 312 and the seal engagement portion 321, thereby increasing the sealing effect.

According to some embodiments of the present invention, as shown in fig. 1-5, the input end part 30 may further include: a stopper 34 and a stopper return 35, the stopper 34 being provided on the cover 32, and the stopper 34 being movable between a first position and a second position in a radial direction of the cover 32. As shown in fig. 1-4, the stop member 34 is located at the first position to stop the cover 32 from moving to the open position, the cover 32 is normally located at the closed position, and the stop member 34 is normally located at the first position to prevent the cover 32 from being pushed by a user to extend into the recess 311, thereby preventing electric shock. As shown in fig. 5, the stop member 34 is positioned at the second position to release the cover 32, so that the input terminal member 30 and the output terminal member 40 are electrically connected.

In addition, as shown in fig. 1 to 5, the output terminal part 40 may include: an output terminal base 43, an output conductive part 42, and a magnetic actuator 44, wherein the output conductive part 42 may be connected to the output terminal base 43, and the magnetic actuator 44 may be connected to the output terminal base 43. The stop 34 may be a magnetically attractable member such as a magnet, ferrous metal, or the like. A magnetic drive 44 may be coupled to the output end base 43 and the magnetic drive 44 may magnetically cooperate with the stop 34 such that the stop 34 is formed as a magnetic self-locking pin that is movable between a first position and a second position under the influence of a magnetic force.

Therefore, as shown in fig. 1 and fig. 2, when the input end member 30 and the output end member 40 are separated, the output conductive part 42 moves out of the groove 311, the cover 32 is located at the closed position, and the magnetic driving member 44 is far away, the stop member 34 can be always located at the first position, so that the input end member 30 is self-locked, and the electric shock accident caused by the user pushing the cover 32 to extend into the groove 311 is prevented.

As shown in fig. 19 and 20, the upper cover body 10 has an installation space 101 therein, and the power coupler 20 of the ultrasonic vibrator assembly may be disposed in the installation space 101, wherein the input end member 30 may be electrically connected to an external power source or an electricity storage assembly, etc. directly or indirectly, so that the input end member 30 may transmit power of the external power source or the electricity storage assembly to the output end member 40, and further, the output end member 40 may transmit the power to a power consuming component of the upper cover assembly 100, for example, the ultrasonic vibrator 60, etc. Thus, the power coupling and power transmission functions can be realized by the cooperation of the input end part 30 and the output end part 40 of the power coupler 20.

However, since the cooking appliance 200 is generally used in a kitchen, the humidity of the working environment is high, and during the working process of the cooking appliance 200, certain steam, oil smoke, dust, or the like may be generated, if the gap between the input end member 30 and the output end member 40 is not sealed, steam, or the like may easily enter the power coupler 20 through the gap, which may cause a short circuit of the electrical connection structure, and may cause the power coupler 20 to fail to transmit power, which may cause a serious electric leakage or fire, and may seriously affect the service life of the power coupler 20 and the safety performance of the cooking appliance 200.

Therefore, liquid, steam, oil smoke, dust and the like can be prevented from entering the power coupler 20 through the gap between the output end part 40 and the input end part 30, so that the power coupler 20 can normally work, the service life of the power coupler 20 is prolonged, electric shock accidents or fire accidents can be prevented from happening, and the cooking appliance 200 is safer to use.

According to the utility model discloses cooking utensil 200's upper cover subassembly 100, through set up sealing member 50 in installation space 101 to sealing member 50 and output part 40 and input part 30 sealing contact respectively, can seal up the clearance between output part 40 and the input part 30, prevent that power coupler 20 from receiving in operational environment or cooking utensil 200 work in the influence of impurity such as the liquid that produces, steam, oil smoke, dust, be favorable to improving power coupler 20's life and cooking utensil 200's security performance.

According to some embodiments of the present invention, the input end member 30 and the output end member 40 may be separable, as shown in fig. 21 and 23, and the sealing member 50 may be configured to seal a gap between the notch edge and the cover 32 when the input end member 30 and the output end member 40 are separated, as shown in fig. 21 and 22.

Accordingly, when the input terminal member 30 is separated from the output terminal member 40, the reliability and safety of the electrical connection structure of the input terminal member 30 can be significantly improved by the sealing portion 312 and the seal fitting portion 321 fitting the gap between the seal notch edge and the cover 32 and further sealing by the sealing member 50. In addition, the sealing member 50 can seal not only the gap between the input terminal member 30 and the output terminal member 40 when the input terminal member 30 and the output terminal member 40 are coupled, but also the gap between the notch edge and the cover 32 when the input terminal member 30 and the output terminal member 40 are separated, and functions are more integrated.

In some embodiments of the present invention, as shown in fig. 5 and 10, the sealing member 50 may include: a first annular seal 51, a second annular seal 52 and a third annular seal 53.

As shown in fig. 21 to 22 and 23 to 24, when the input and output end members 30 and 40 are connected, the first annular seal portion 51 may abut against the output end member 40, the second annular seal portion 52 may sealingly connect with the output end member 40, the third annular seal portion 53 may abut between the upper cover body 10 and the input end base 31, and the first annular seal portion 51, the second annular seal portion 52, and the third annular seal portion 53 are connected together.

At this time, the sealing member 50 is brought into sealing contact with the output end member 40 by the first annular sealing portion 51 and the second annular sealing portion 52, and is brought into sealing contact with the input end member 30 by the third annular sealing portion 53, so that even if steam or the like generated by the operation of the cooking appliance 200 leaks into the installation space 101, impurities such as steam cannot enter the gap between the input end member 30 and the output end member 40 through the sealing member 50, and the sealing member 50 has a good steam shielding function. Moreover, the sealing element 50 realizes two-stage sealing with the output end part 40 through the first annular sealing part 51 and the second annular sealing part 52, so that the sealing effect is better, and the steam protection effect is better.

As shown in fig. 21 to 22, when the input end member 30 and the output end member 40 are separated, the first annular seal portion 51 abuts against the lid 32, the third annular seal portion 53 abuts between the upper lid body 10 and the input end base 31, and the first annular seal portion 51, the second annular seal portion 52, and the third annular seal portion 53 are connected together.

At this time, the sealing member 50 is brought into sealing contact with the input terminal member 30 by the first and third annular sealing portions 51 and 53, and prevents the input terminal member 30 from being damaged by water inflow due to high humidity in the surrounding environment such as a kitchen when the cooking appliance 200 is in a non-operating state.

It should be noted that, in the schematic diagrams shown in fig. 19 to 24, the sealing member 50 has an overlapping portion with the input end member 30 or the output end member 40, which indicates that the sealing member 50 is closely attached to the input end member 30 or the output end member 40 to achieve sealing, and does not indicate that the sealing member 50 is inserted into the input end member 30 or the output end member 40. In addition, in the schematic diagrams shown in fig. 19 and 20, the first annular seal portion 51 is shown to be simultaneously abutted against the input end member 30 and the output end member 40, for the purpose of facilitating comparison of the sealed state of the first annular seal portion 51 in the state of connection and disconnection of the input end member 30 and the output end member 40, whereas in practice, when the input end member 30 is disconnected from the output end member 40, the first annular seal portion 51 is abutted against the input end member 30 as shown in fig. 21 and 22, and when the input end member 30 is connected to the output end member 40, the first annular seal portion 51 is abutted against the output end member 40 as shown in fig. 23 and 24.

The utility model discloses do not do special restriction to the seal structure of second annular sealing 52 and output end member 40, optionally, as shown in fig. 17, fig. 18 and fig. 24, the outer peripheral face of output end member 40 can be equipped with outside convex mesa 401, second annular sealing 52 can offset with mesa 401 to realize that second annular sealing 52 is sealed with the contact of output end member 40, second annular sealing 52 is simple with the seal structure of output end member 40, easily dismouting, and sealed effectual.

Further, as shown in fig. 24-26, the second annular seal portion 52 may include: a first ring segment 521 and a second ring segment 522, wherein the first ring segment 521 is closer to the input member 30 than the second ring segment 522. The first ring segment 521 may be connected to the first annular sealing portion 51 or the third annular sealing portion 53, and the first ring segment 521 extends obliquely outward in a direction away from the input end member 30 with respect to the axial direction of the seal 50, and the second ring segment 522 is disposed obliquely inward in a direction away from the input end member 30 with respect to the axial direction of the seal 50, so that the axial cross section of the second annular sealing portion 52 is formed into a bent shape such as a V shape or an L shape, and an end of the second ring segment 522 away from the first ring segment 521 abuts against the table top 401. Here, "inward" refers to a direction toward the axis of the seal 50, and "outward" refers to a direction away from the axis of the seal 50.

Of course, the inclination directions of the first ring segment 521 and the second ring segment 522 may be interchanged, and specifically, the first ring segment 521 may be disposed in an inclined manner inward and in a direction away from the input end member 30 with respect to the axial direction of the seal 50, and the second ring segment 522 may extend in an inclined manner outward and in a direction away from the input end member 30 with respect to the axial direction of the seal 50, so as to form the second annular sealing portion 52 into a bent shape, which is also within the scope of the present invention.

Because the axial cross section of the second annular sealing portion 52 is formed into a bent shape, when the second annular sealing portion 52 abuts against the table top 401, the axial span of the second annular sealing portion 52 can be adjusted, so that the included angle formed by the first ring segment 521 and the second ring segment 522 can be changed, the acting force between the second ring segment 522 and the table top 401 and the acting force between the first annular sealing portion 51 and the third annular sealing portion 53 can be improved, the second annular sealing portion 52 forms a pre-tightening axial seal with the table top 401, and the sealing effect of the sealing element 50 is improved.

For example, in the specific embodiment shown in fig. 24-26, the first ring segment 521 is disposed obliquely downward with respect to the axial direction of the seal 50 and in a direction away from the axis of the seal 50, and the second ring segment 522 is disposed obliquely downward with respect to the axial direction of the seal 50 and in a direction close to the axis of the seal 50, so that the axial cross sections of the first ring segment 521 and the second ring segment 522 are formed in a V shape that opens toward the middle of the seal 50. Of course, in other embodiments, the axial cross-section of the second annular sealing portion 52 may also be formed in a V-shape facing away from the middle of the seal 50.

Further, as shown in fig. 26, the included angle between the first ring segment 521 and the second ring segment 522 is α, and α satisfies 45 ° - α -90 °, for example, in some specific embodiments, α may be 50 °, 55 °, 60 °, 65 °, 70 °, 75 °, 80 °, and 85 °, respectively, in the above-mentioned angle range, the second annular sealing portion 52 has a larger axial compressibility, which is beneficial to improving the acting force with the output end member 40 and improving the sealing effect, and the bent shape is easier to machine and form, and the machining process is less difficult, which is beneficial to improving the production efficiency and reducing the production cost.

In some embodiments of the present invention, as shown in fig. 22-26, the first annular sealing portion 51 may be configured as an annular bead located on the inner circumferential surface of the sealing member 50. When the input end part 30 is connected with the output end part 40, the annular convex rib can form extrusion sealing with the outer peripheral surface of the output end part 40; when the input end member 30 and the output end member 40 are separated, the annular bead may abut against the input end member 30 to form a self-tightening seal.

Alternatively, as shown in fig. 26, the annular bead has an extension H in the axial direction of the seal 50, and H satisfies: 0.4mm ≦ H ≦ 1mm, e.g., H may be 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, etc., respectively, in some embodiments.

In the repeated assembling and disassembling process of the output end part 40, the output end part 40 and the first annular sealing part 51 move relatively and rub against each other, and within the size range, the mechanical strength of the fixing structure of the first annular sealing part 51 is higher, so that the breakage is not easy to occur, the sealing performance is not influenced, and the assembling and disassembling difficulty caused by the overlarge moving resistance of the output end part 40 due to the overlarge extension size of the first annular sealing part 51 along the axial direction of the sealing element 50 can be avoided.

It should be noted that the extension H of the annular rib in the axial direction of the seal 50 may be understood as the maximum extension of the annular rib in the axial direction of the seal 50, for example, in the example shown in fig. 11, the extension H of the end of the annular rib away from the middle of the seal 50 in the axial direction of the seal 50 is the maximum.

Further, as shown in fig. 20 and 26, at least an inner end of the annular bead facing the axial end surface of the input end member 30 may be formed as a slope 511, the slope 511 extending obliquely inward in a direction away from the input end member 30 with respect to the axial direction of the seal 50. Here, "inner end" refers to an end near the middle of the seal 50, and "inward" refers to a direction near the middle of the seal 50.

As shown in fig. 21 and 22, when the input terminal member 30 and the output terminal member 40 are separated, the inclined surface 511 may abut against the input terminal member 30; as shown in fig. 23 and 24, the inclined surface 511 may abut against the output terminal member 40 when the input terminal member 30 and the output terminal member 40 are connected.

Thus, the inclined surface 511 can be used for sealing contact with structures having different radial dimensions, that is, the radial dimension of the portion of the input end member 30 abutting against the inclined surface 511 and the radial dimension of the portion of the output end member 40 abutting against the inclined surface 511 may be the same or different, and the applicability of the inclined surface 511 sealing is further enhanced. And along the radial inward direction of sealing member 50, the thickness that at least a part of annular bead extends along the axial of sealing member 50 reduces gradually, makes annular bead change when making with input end part 30 or output end part 40 counterbalance and takes place the deformation more easily to improve the effort of counterbalance, and then improve sealed effect.

Still further, as shown in fig. 20 and 26, the annular rib may have a radial end surface 512, and the radial end surface 512 extends along the axial direction of the sealing element 50, so that the thickness of the radial inner end of the annular rib extending along the axial direction of the sealing element 50 is not too small to cause serious abrasion and affect the sealing performance. And the radial end surface 512 can be smoothly connected with the inclined surface 511, which not only facilitates the processing, but also reduces the frictional resistance between the annular rib and the input end member 30 and the output end member 40.

Alternatively, as shown in fig. 21 and 22, the radial end surface 512 may abut the input member 30 when the input member 30 and the output member 40 are separated; as shown in fig. 23 and 24, the radial end surface 512 may abut against the output end member 40 when the input end member 30 and the output end member 40 are connected. Therefore, the area of the annular convex rib in sealing contact with the input end part 30 and the output end part 40 is larger, and the sealing effect is better.

According to some embodiments of the present invention, as shown in fig. 22 and 24, the input end member 30 may further have a sealing end surface 301, the third annular sealing portion 53 may be located at one axial end of the sealing member 50, and the third annular sealing portion 53 abuts against the sealing end surface 301 to achieve sealing contact with the input end member 30. The first annular seal portion 51 may be provided on an inner peripheral surface of the third annular seal portion 53 so as to be in sealing contact with the input end member 30 or the output end member 40.

An axial end of the outer peripheral surface of the third annular seal portion 53 may be provided with an outer protrusion 54, an inner peripheral surface of the installation space 101 may be provided with an inner protrusion 102 protruding inward, the outer protrusion 54 may be caught between the inner protrusion 102 and the seal end surface 301, and a radially inner end surface of the inner protrusion 102 may abut against the outer peripheral surface of the third annular seal portion 53. Therefore, the inner protrusion 102, the outer protrusion 54, the sealing end surface 301 and the third annular sealing portion 53 are matched to fix the axial position and the radial position of the sealing element 50, so that the sealing element 50 is prevented from being shifted during use to affect the sealing effect, the inner protrusion 102, the outer protrusion 54 and the sealing end surface 301 can seal a gap between the input end part 30 and the inner circumferential surface of the installation space 101, and steam and the like are prevented from entering the installation space 101 and leaking to the outside to cause the abnormal operation of the cooking appliance 200.

In some embodiments of the present invention, as shown in fig. 17 and 18, the table top 401 may be provided with a mounting groove 402, a fixing hole 403 may be disposed in the mounting groove 402, and the fastening member may pass through the fixing hole 403 to connect with the upper cover body 10, so as to connect the output end member 40 with the upper cover body 10, and the connection structure of the output end member 40 is simple and firm, and is not easy to loosen and assemble. A baffle plate 41 may be disposed in the mounting groove 402 for shielding the fastener, as shown in fig. 20, and the second annular sealing portion 52 may abut against at least one of the baffle plate 41 and the table top 401 to prevent the aperture of the fixing hole 403 or the gap of the fastener surface from affecting the sealing effect of the second annular sealing portion 52. Alternatively, the upper surface of the baffle 41 may be flush with the mesa 401.

In some embodiments of the present invention, as shown in fig. 19 and 23, the inner side surface of the upper cover body 10 may be provided with a mounting hole 121 communicating with the mounting space 101, and the output end member 40 of the ultrasonic vibrator assembly is electrically connected to the ultrasonic vibrator 60 to supply power to the ultrasonic vibrator 60, so that the ultrasonic vibrator 60 can perform ultrasonic processing on the food material in the cooking utensil 200, thereby improving the nutrition extraction effect and cooking efficiency of the food material.

Alternatively, at least one of the ultrasonic vibrator 60 and the output terminal member 40 may be hermetically connected to the edge of the mounting hole 121, so that steam or the like in the cooking cavity of the cooking appliance 200 is prevented from entering the mounting space 101 through the mounting hole 121, and the steam protection effect of the power coupler 20 may be further improved.

For example, in the example shown in fig. 19 and 23, the upper portion of the ultrasonic vibrator 60 passes through the mounting hole 121 from bottom to top to extend into the mounting space 101 to be connected to the output end member 40, the outer peripheral surface of the ultrasonic vibrator 60 is provided with a mounting flange, the mounting flange abuts against the lower surface of the edge of the mounting hole 121, and a sealing ring is provided between the mounting flange and the lower surface of the edge of the mounting hole 121 to seal a gap between the mounting flange and the edge of the mounting hole 121, thereby improving the sealing connection effect between the ultrasonic vibrator 60 and the mounting hole 121.
