These bubbles, filled with steam or air, are in an unstable state and when they suddenly close, they generate shock waves and thus have a great pressure in a local micro area. Many physical and chemical effects are associated with this cavitation phenomenon due to the non-linear vibration of the bubbles and the large pressure generated when the bubbles collapse. Therefore, when the medium transmits ultrasonic excitation to the solid food material in the medium, the food material can be subjected to ultrasonic treatment under the action of the ultrasonic cavitation effect.

Therefore, in the ultrasonic process, the separating cover 40 can separate the solid food material in the cooking cavity 101 from the ultrasonic vibrator device 30, and the liquid medium or the solid food material with the volume smaller than the aperture of the liquid passing hole 402 can enter the cover cavity 401 through the liquid passing hole 402 and contact with the ultrasonic vibrator device 30, so that when the ultrasonic vibrator device 30 works, high-frequency vibration can be transmitted to the solid food material outside the cover cavity 401 through the medium, and ultrasonic processing of the food material is realized. While the ultrasonic effect is ensured, the solid food material with the larger volume cannot contact with the ultrasonic vibrator device 30, and the solid food material with the smaller volume has smaller influence on the operation of the ultrasonic vibrator device 30, even can be ignored. Therefore, the partition cover 40 can effectively reduce the load on the ultrasonic vibrator device 30, and the load is simple and stable, so that the ultrasonic vibrator device 30 is not easy to drift, the frequency tracking is easy, the working state of the ultrasonic vibrator device 30 is more stable, the power is more stable, sharp abnormal sound is not easy to generate, and the use feeling of a user is improved.

According to some embodiments of the present invention, as shown in fig. 4 to 6, the separation cover 40 may be detachably connected to the ultrasonic vibrator device 30, specifically, the separation cover 40 may have an installation portion 41, the ultrasonic vibrator device 30 may have an installation fitting portion 31, and the installation portion 41 and the installation fitting portion 31 may be connected in a snap-fit manner, so as to realize the connection of the separation cover 40 and the ultrasonic vibrator device 30. The clamping structure is firm in fixation and easy to disassemble and assemble, assembly efficiency is improved, and machining process difficulty and production cost are reduced.

In an embodiment in which the separation cover 40 is detachably connected to the upper cover assembly 20, the separation cover 40 may have a mounting portion 41, the upper cover assembly 20 may have a mounting mating portion 31, and the mounting portion 41 and the mounting mating portion 31 may be connected by a snap connection to realize the connection between the separation cover 40 and the upper cover assembly 20, which is also within the protection scope of the present invention.

Further, as shown in fig. 6, the mounting fitting portion 31 may be a groove, and the mounting portion 41 may be a protrusion, that is, the separation cover 40 may have a protrusion, and the upper cover assembly 20 or the ultrasonic vibrator device 30 may have a groove, and the protrusion may be snapped into the groove to achieve the snap-fit connection of the mounting portion 41 and the mounting fitting portion 31, thereby achieving the fixation of the separation cover 40. The clamping structure is simple and firm, the assembly and disassembly are easy, a user can clean the upper cover assembly 20, the ultrasonic vibrator device 30 and the separation cover 40 conveniently, the groove and the protrusion are simple in structure and easy to machine and form, and the production cost is reduced.

Of course, the arrangement positions of the groove and the protrusion may be interchanged, and specifically, the mounting fitting portion 31 may be a protrusion, and the mounting portion 41 may be a groove, that is, the separation cover 40 may have a groove, and the upper cover assembly 20 or the ultrasonic vibrator device 30 may have a protrusion, and the groove and the protrusion are engaged to fix the separation cover 40. In other words, one of the mounting portion 41 and the mounting engagement portion 31 is a groove, and the other of the mounting portion 41 and the mounting engagement portion 31 is a projection that can be snapped into the groove.

Still further, one of the grooves and the projections may extend annularly along the circumferential direction of the partition cover 40, and the other of the grooves and the projections may include a plurality of ones spaced apart along the circumferential direction of the partition cover 40. From this, the recess is gone into to the arch card more easily, can realize separating the joint of cover 40 from a plurality of positions of the circumference of separating cover 40 and fix, and it is more stable to separate cover 40 and fix, is difficult for droing. And the groove and the bulge are not provided with a fixed installation angle in the circumferential direction of the separation cover 40 when being clamped, so that alignment is not needed, and the separation cover 40 is easier to install.

For example, in the example shown in fig. 6 to 9, the ultrasonic transducer device 30 is provided with the mounting fitting portion 31, the mounting fitting portion 31 is a groove extending in a ring shape in the circumferential direction of the ultrasonic transducer device 30, and the mounting portion 41 is a projection provided on a side wall surface of the cover cavity 401 of the partition cover 40, the projection including four projections distributed at intervals in the circumferential direction of the partition cover 40. When the protrusion is clamped into the concave ring or is separated from the concave ring for clamping, the required deformation of the separation cover 40 or the ultrasonic vibrator device 30 is smaller, and the clamping structure is easier to disassemble and assemble. Of course, the number of projections includes, but is not limited to, four as shown in FIG. 9, and in other embodiments, the projections may include two, three, five, or more spaced apart circumferentially along the divider shroud 40. Alternatively, a plurality of protrusions may be uniformly spaced along the circumferential direction of the partition cover 40, which is beneficial to improving the clamping stability of the partition cover 40.

In addition, the groove wall surface of the recessed ring may be arc-shaped, each protrusion may be formed as a spherical arc-shaped convex rib, and the spherical arc-shaped surface may be fitted with the outer circumferential surface of the ultrasonic vibrator device 30 to guide in the process of being fitted into the recessed ring, so that the mounting of the partitioning cover 40 is easier. When the convex rib is separated from the concave ring, the spherical arc surface can be matched with the arc-shaped groove wall surface of the concave ring for guiding, so that the separation cover 40 is easier to disassemble. And the recess and the protruding simple structure of above-mentioned structure, easily processing, in the dismouting in-process that relapses, protruding stable in structure is difficult for taking place to warp, is favorable to improving the fixed reliability of separation cover 40.

In some embodiments of the present invention, as shown in fig. 7-9, the maximum protrusion height of the protrusion is H, and H satisfies: h is more than or equal to 1.3mm and less than or equal to 1.5 mm. If the protruding height of the protrusion is too high, the required deformation of the separating cover 40 is increased, the protrusion is difficult to be clamped into the groove, and if the protruding height of the protrusion is too low, the protrusion and the groove are easy to loosen. In the size range, the bulge and the groove are easier to disassemble and assemble, the bulge and the groove can be firmly clamped, and the separation cover 40 is not easy to fall off. For example, in some embodiments, the maximum protrusion height H of the protrusion may be 1.35mm, 1.4mm, 1.45mm, and the like, respectively.

In addition, the interference fit L of the protrusion and the groove can meet the following requirements: l is more than or equal to 0.3mm and less than or equal to 0.8mm, which is beneficial to further improving the stability of the matching of the protrusion and the groove, and the separation cover 40 is not easy to shake in the cooking process, so that the separation cover 40 is not easy to fall off. For example, in some embodiments, the interference fit L of the protrusion and the groove may be 0.4mm, 0.5mm, 0.6mm, 0.7mm, and the like.

Alternatively, in some embodiments, the edge of the cover cavity 401 of the separation cover 40 may be rounded, for example, by flattening the edge of the cover cavity 401 of the separation cover 40, so that the user is not easily cut by the edge of the cover cavity 401, and the separation cover 40 is more safely assembled and disassembled. In other embodiments, as shown in fig. 7 and 8, the rim of the enclosure cavity 401 of the separation enclosure 40 may be crimped, i.e. the rim of the enclosure cavity 401 is formed with a crimp 42. Specifically, the rim of the cap cavity 401 may extend outward with respect to the axial direction of the partition cap 40, extend downward, and then extend inward to form the bead 42, with smooth transition of the respective extensions. The curled edge 42 can prevent a user from being cut by the edge of the cover cavity 401 when the separation cover 40 is disassembled and assembled, and can improve the structural strength of the edge of the cover cavity 401 of the separation cover 40, so that the separation cover 40 is firmer in structure and is not easy to fall off. Here, "extends outward in the axial direction with respect to the partition cover 40" may be understood as extending in a direction away from the axis of the partition cover 40, and "extends inward" may be understood as extending in a direction close to the axis of the partition cover 40.

According to some embodiments of the present invention, as shown in fig. 7-9, the separation cover 40 may include: a side panel 43 and a bottom wall 44, the side panel 43 being connectable to a rim of the bottom wall 44, and the side panel 43 extending towards a side of the bottom wall 44 to form the enclosure 401 in cooperation with the bottom wall 44. Optionally, at least one of the side wall 43 and the bottom wall 44 may be provided with a liquid passing hole 402, so that the medium in the cooking cavity 101 can enter the cover cavity 401 through the liquid passing hole 402 and directly contact the ultrasonic vibrator device 30.

For example, in the example shown in fig. 7 and 9, the side gusset 43 is provided with a plurality of liquid passing hole groups spaced apart in the axial direction of the partition cover 40, each liquid passing hole group including a plurality of liquid passing holes 402 spaced apart in the circumferential direction of the partition cover 40; the bottom wall 44 is provided with a liquid passing hole 402 at the center and a plurality of liquid passing hole groups which surround the center and are distributed at intervals along the radial direction of the separation cover 40, and each liquid passing hole group comprises a plurality of liquid passing holes 402.

From this, under the prerequisite of guaranteeing to separate cover 40's structural strength, it is more to separate the quantity of crossing liquid hole 402 on the cover 40, and open area is bigger, is favorable to improving the efficiency that the medium got into cover chamber 401, and improves the efficiency of the ultrasonic wave in the cover chamber 401 transmission outside cover chamber 401, reduces energy loss, and side wall 43 and diapire 44 all are equipped with and cross liquid hole 402, make the ultrasonic wave can follow more directions and effectively transmit outside cover chamber 401, are favorable to improving the culinary art effect.

It should be noted that, in the embodiment where the side wall 43 and the bottom wall 44 are both provided with the liquid passing hole 402, the size of the liquid passing hole 402 provided in the side wall 43 and the size of the liquid passing hole 402 provided in the bottom wall 44 may be the same or different, which is within the protection scope of the present invention.

Further, as shown in fig. 5 and 6, the side gusset 43 may be connected to the upper cover assembly 20 or the ultrasonic transducer device 30. In the embodiment that the partition cover 40 is provided with the mounting portion 41, the mounting portion 41 can be arranged on the side wall 43, and the mounting portion 41 arranged on the side wall 43 is easier, which is beneficial to reducing the difficulty of the processing technology and has more reasonable structural design.

Alternatively, the radial cross-sectional area of the hood cavity 401 may gradually increase, gradually decrease, or remain constant upward along the axial direction of the cooking cavity 101, depending on the structure of the vibration rod 34 protruding into the hood cavity 401, the ultrasonic transmission requirements, the difficulty of the manufacturing process of the partition hood 40, and the ease of installation of the partition hood 40. It should be noted that, here, the variation manner of the radial cross-sectional area of the cover cavity 401 upward along the axial direction of the cooking cavity 101 may include one of gradually increasing, gradually decreasing and constantly maintaining or a combination of at least two of the three manners, so that the separation cover 40 may have different structures and sizes to meet more use requirements.
