Description

Technical Field

[0001] The invention relates to the field of refrigeration and freezing devices, and in particular to an ultrasonic-assisted processing chamber and a refrigerator for low-temperature space. Background Art

[0002] In recent years, along with consumers' expectations for a higher quality lifestyle, people's pursuit of food freezing quality (such as freezing quality, pickling quality, etc.) is increasing.

[0003] Users usually store meat products in the freezer of the refrigerator, but meat products will produce large ice crystals during the freezing process, causing damage to cells. Moreover, as the storage time increases, the meat products stored in the freezer will gradually become dull in color, lose juice seriously, smell bad, and have a poor taste, seriously affecting the quality of the food. For this reason, refrigerators with quick-freezing functions have appeared on the market, such as quick-freezing trays, which improve the freezing quality of meat to a certain extent. However, for refrigerators with quick-freezing functions in the prior art, during the process of freezing meat products, meat products will still undergo a crystallization process from the outside to the inside, and it is not possible to completely avoid cells being punctured during the freezing process, thereby causing the loss of nutrients in the meat products. Moreover, when the existing quick-freezing trays are used in refrigerators, due to space limitations, the small amount of freezing medium in the quick-freezing trays is not enough to absorb the large temperature fluctuations generated during the defrosting process of the refrigerator, resulting in unstable temperature of the meat products, which in turn leads to thawing and recrystallization of the meat products, aggravating the damage to the texture of the meat products themselves, and thus affecting the freezing quality of the food. Freezing quality

[0004] In addition, currently users usually marinate and store food by mixing the marinade and food to be stored and then placing them directly in the refrigerator to stand. The low temperature environment of the refrigerator can cause the marinating time to be as long as several hours, and long-term marinating seriously affects the freshness of the food.

[0005] How to design an independent compartment that can be used in a refrigerator and can realize the above auxiliary functions is an urgent problem to be solved. Summary of the invention

[0006] In view of the above problems, the present invention is proposed to provide an ultrasonic assisted treatment chamber and a refrigerator for low temperature space that overcome the above problems or at least partially solve the above problems.

[0007] An object of the present invention is to provide an ultrasonic-assisted processing chamber for a refrigerator that can achieve rapid freezing of stored food, thereby improving freezing quality.

[0008] A further object of the present invention is to utilize the ultrasonic treatment chamber to quickly pickle and store food materials, thereby increasing the pickling speed and thus improving the pickling quality.

[0009] Another further object of the present invention is to provide a refrigerator with an ultrasonic-assisted processing chamber, thereby providing an environment suitable for rapid freezing and rapid pickling for stored food.

[0010] In particular, the present invention provides an ultrasonic assisted treatment chamber for a cryogenic space, comprising:

[0011] A container base assembly, the upper end of which is opened to form a top opening for taking out and placing stored food;

[0012] A container upper cover assembly is disposed above the container base assembly, used to close the top opening and define a receiving cavity with the container base assembly, the receiving cavity is used to receive and store food, wherein a first interlayer cavity is provided inside the container upper cover assembly, and the first interlayer cavity is filled with an interlayer medium; and

[0013] At least one first ultrasonic generator is arranged on a side of the container upper cover assembly facing the accommodating cavity and is used to apply ultrasonic waves to the stored food in the accommodating cavity, and utilizes an interlayer medium to absorb heat emitted during the application of ultrasonic waves by at least one first ultrasonic generator.

[0014] Furthermore, the container upper cover assembly includes a top cover and a top seat, and the top cover is sealingly buckled on the top seat to form a first compartment cavity between the top cover and the top seat.

[0015] Furthermore, the top seat includes a concave portion which is gradually contracted from top to bottom, and the concave portion is arranged at the center of the top seat for containing the interlayer medium; wherein

[0016] At least one first ultrasonic generator is arranged in close contact with the lower surface of the recessed portion, and at least one first ultrasonic generator is fixedly arranged at the center of the lower surface of the recessed portion.

[0017] Furthermore, the container base assembly includes an inner liner and a container shell, the inner liner is inserted into the container shell, and a second interlayer cavity is formed by sealing between the inner liner and the container shell, and the second interlayer cavity is filled with an interlayer medium;

[0018] The surface of the interlayer medium in the second interlayer cavity at least exceeds the bottom end of the inner container.

[0019] Furthermore, the interlayer medium is selected so that its solidification temperature is between -40°C and 0°C, and its specific heat capacity is between 1KJ / (kg·K) and 5KJ / (kg·K).

[0020] Furthermore, the ultrasonic-assisted processing chamber of the present invention also includes at least one second ultrasonic generator, which is arranged below the container base assembly and is used to generate ultrasonic waves, and at least a portion of the ultrasonic waves generated by the second ultrasonic generator are applied to the stored food through the container base assembly.

[0021] Further, at least one second ultrasonic generator is fixed to the bottom of the container base assembly, and at least one second ultrasonic generator is disposed at the center of the container base assembly.

[0022] Furthermore, the first ultrasonic generator and the second ultrasonic generator are both ultrasonic vibrators or ultrasonic chips.

[0023] Furthermore, the sound intensity of the ultrasonic signal generated by the first ultrasonic generator and the second ultrasonic generator is 0.05 W / cm 2 ~2W / cm 2 .

[0024] The present invention also provides a refrigerator, comprising:

[0025] The housing; and

[0026] Any of the above-mentioned ultrasonic-assisted processing chambers is arranged in the box.

[0027] The ultrasonic-assisted processing chamber of the present invention defines an independent accommodating chamber for accommodating stored food by setting a container base assembly and a container upper cover assembly. By setting at least one first ultrasonic generator on the side of the container upper cover assembly facing the accommodating chamber, ultrasonic waves are applied to the stored food in the accommodating chamber, and the freezing process can be assisted by ultrasonic action. Since the interior of the container upper cover assembly also defines a first interlayer cavity, and the first interlayer cavity is filled with an interlayer medium, on the one hand, the temperature change rate of the container upper cover assembly 200 can be kept smooth and stable as much as possible, thereby ensuring that the stored food is cooled evenly and the temperature change rate is stable. On the other hand, it can absorb the heat emitted during the application of ultrasonic waves by the first ultrasonic generator 400, which will not affect the freezing efficiency of the entire ultrasonic-assisted freezing device, thereby providing an environment for rapid freezing of stored food and ensuring the freezing quality of stored food.

[0028] Furthermore, the ultrasonic-assisted processing chamber of the present invention can achieve the distribution of interlayer medium in the up-down direction and the left-right direction of the accommodating chamber by respectively setting the first interlayer cavity and the second interlayer cavity in the container upper cover assembly and the container base assembly, and respectively filling the interlayer medium in the first interlayer cavity and the second interlayer cavity. Since the specific heat capacity of the interlayer medium is large, the temperature of the interlayer medium itself does not change much after absorbing the cold in the accommodating chamber, so that the temperature field change in the accommodating chamber tends to be stable, thereby ensuring that the stored food is cooled evenly and the temperature change rate is stable, thereby further improving the quality of the stored food.

[0029] Furthermore, the ultrasonic-assisted processing chamber of the present invention can also be used to quickly marinate stored food. By arranging at least one first ultrasonic generator on the side of the container upper cover assembly facing the accommodating cavity, the ultrasonic wave emitted by the first ultrasonic generator acts on the stored food in the accommodating cavity, thereby accelerating the speed at which the marinade enters the stored food, making the marinade more uniform in the stored food, and improving the marinating quality.

[0030] Furthermore, the refrigerator of the present invention is specially provided with an ultrasonic assisted processing chamber and a low-temperature space providing a specified temperature for the ultrasonic assisted processing chamber, thereby creating an environment for storing food, rapidly freezing food, and rapidly pickling food, so as to meet the needs of users for improving food quality.

[0037] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to enable the scope of the present invention to be fully communicated to those skilled in the art.

[0038] Figure 1FIG. 7 is a schematic structural diagram of a refrigerator 700 according to an embodiment of the present invention. Figure 1 As shown, the refrigerator 700 of the present invention may generally include a box body 710 and an ultrasonic assisted treatment chamber 100 disposed in the box body. The box body 710 may include an outer shell and a storage liner. The outer shell wraps the storage liner, and the space between the outer shell and the storage liner is filled with a heat-insulating material (forming a foaming layer) to reduce the heat dissipation of the storage liner to the outside.

[0039] In this embodiment, there can be multiple storage liners, and multiple storage spaces 711 can be defined in each storage liner. The multiple storage spaces 711 can be configured as refrigerators, freezers, temperature-changing chambers, etc. The specific number and functions of the storage spaces 711 can be configured according to pre-determined requirements.

[0040] Specifically, Figure 1 As shown, one of the storage spaces 711 is configured as a low temperature space. When the low temperature space is configured to store at a temperature of -40°C to 0°C, the ultrasonic-assisted processing chamber 100 of this embodiment is used to quickly freeze the stored food, thereby improving the frozen storage quality of meat products.

[0041] In some alternative embodiments, when the low temperature space is configured to store at a temperature above 0°C, the ultrasonic-assisted processing chamber 100 can be used to place food to be marinated (i.e. food that has been smeared with marinade or immersed in marinade) and use ultrasound to accelerate the marinating speed to achieve a quick marinating function. Of course, those skilled in the art can also set other temperature ranges after knowing the technical solution of this embodiment, which will not be elaborated here.

[0042] The refrigerator 700 of the embodiment of the present invention can realize the functions of rapid freezing and rapid pickling by providing the ultrasonic assisted treatment chamber 100, and by providing a low-temperature space of a specified temperature for the ultrasonic assisted treatment chamber 100, an environment is built to realize rapid freezing or pickling of stored food, thereby effectively ensuring the quality of stored food. The structure of the ultrasonic assisted treatment chamber 100 is specifically introduced below.

[0043] like Figures 2 to 4 As shown, Figure 2 is a schematic structural exploded view of an ultrasound-assisted treatment chamber 100 according to one embodiment of the present invention, Figure 3 FIG. 1 is a schematic structural exploded view of an ultrasonic-assisted treatment chamber 100 according to an embodiment of the present invention. Figure 4 1 is a schematic cross-sectional view of an ultrasonic assisted treatment chamber 100 in a front view according to an embodiment of the present invention, wherein the internal structure of the ultrasonic assisted treatment chamber 100 is shown.

[0044] The present invention provides an ultrasonic-assisted processing chamber 100 for a low-temperature space, which generally may include a container upper cover assembly 200 , a container base assembly 300 and at least one first ultrasonic generator 400 .

[0045] Specifically, the upper end of the container base assembly 300 is opened to form a top opening for taking out and placing stored food. The container cover assembly 200 is disposed above the container base assembly 300 to close the top opening of the container base assembly 300. The container cover assembly 200 and the container base assembly 300 define a receiving cavity 600 ( Figure 2 , Figure 3 (not shown), the accommodating cavity 600 is used to accommodate and store food. Figure 4 As shown, the container cover assembly 200 can be buckled on the container base assembly 300 to form a sealed and independent accommodating chamber 600, and the user can put the stored food (meat food, etc.) in the accommodating chamber 600 for quick freezing. Figure 3 and Figure 4 As shown, a first interlayer cavity 230 is provided inside the container upper cover assembly 200, and an interlayer medium is contained in the first interlayer cavity 230. At least one first ultrasonic generator 400 is disposed on a side of the container upper cover assembly 200 facing the accommodating cavity 600, and is used to apply ultrasonic waves to the stored food in the accommodating cavity 600, and the interlayer medium absorbs the heat emitted during the application of ultrasonic waves by at least one first ultrasonic generator 400.

[0046] When the ultrasonic assisted processing chamber 100 is used to quickly freeze stored food, the ultrasonic assisted processing chamber 100 can be arranged in a low temperature space to cool the stored food in the low temperature space. The user can place the stored food (e.g., meat and other foods) in the ultrasonic assisted processing chamber 100, and then automatically or manually start the freezing program of the refrigerator 700 to start freezing the stored food. For example, for an air-cooled refrigerator 700, after the user starts the freezing program, the power of the compressor, fan, etc. of the refrigerator 700 is increased, and the air volume is increased to quickly cool the stored food. Of course, as known to those skilled in the art, there are other solutions for the freezing technology of the refrigerator 700, which will not be described in detail here in order not to cover up and blur the invention points of the present application.

[0047] As mentioned in the background technology section, the freezing scheme of refrigerators with quick-freezing modes in the prior art only solves the problem of how to freeze quickly, while meat products still undergo a crystallization process from the outside to the inside, and the temperature stability of meat products cannot be guaranteed in the face of large temperature fluctuations, thus affecting the quality of stored food.

[0048] In order to overcome the defects of the above-mentioned prior art, the ultrasonic-assisted processing chamber 100 of the present invention defines an independent accommodating chamber 600 for accommodating stored food by providing a container upper cover assembly 200 and a container base assembly 300; by providing at least one first ultrasonic generator 400 on a side of the container upper cover assembly 200 facing the accommodating chamber 600, ultrasonic waves are applied to the stored food in the accommodating chamber 600, and the freezing process can be assisted by ultrasonic action. In addition, the ultrasonic-assisted processing chamber 100 of the present invention is provided with a first interlayer cavity 230 inside the container upper cover assembly 200, and the first interlayer cavity 230 is filled with an interlayer medium. On the one hand, after the interlayer medium absorbs the cold in the low-temperature environment, its temperature change rate is less than the temperature change rate of the container upper cover assembly 200 and the stored food located below the container upper cover assembly 200. In this way, the interlayer medium can try to ensure that the temperature change rate of the container upper cover assembly 200 remains smooth and stable, thereby ensuring that the stored food is cooled evenly and the temperature change rate is stable, thereby avoiding the internal texture of the stored food from being destroyed and improving the quality of the stored food; on the other hand, since the interlayer medium is also indirectly in contact with the first ultrasonic generator 400 at the same time, it can absorb the heat emitted during the application of ultrasonic waves by the first ultrasonic generator 400, and will not affect the freezing efficiency of the entire ultrasonic-assisted freezing device, thereby providing an environment for rapid freezing of stored food and ensuring the freezing quality of stored food.

[0049] In addition, the ultrasonic assisted processing chamber 100 of the present invention introduces ultrasonic assisted freezing technology, which can quickly freeze the stored food, that is, it can enhance heat transfer during the freezing process of the stored food. The physical effect of ultrasound (cavitation effect) can not only promote the formation of crystal nuclei during the freezing process of the stored food, but also the microbubbles generated by the cavitation effect can serve as new crystal nuclei, change the nucleation temperature of the water inside the stored food, reduce the supercooling of the stored food, and promote the rapid nucleation of ice crystals. Therefore, ultrasound can accelerate the internal heat transfer of the stored food and speed up the cooling of the stored food. At the same time, ultrasound also has a crushing effect on larger ice crystals, forming small and uniform ice crystals, reducing damage to cells and ensuring the freshness of the stored food.

[0050] When the ultrasonic-assisted processing chamber 100 is used to quickly marinate stored food, the ultrasonic-assisted processing chamber 100 can be set in a low-temperature space to cool the stored food in the low-temperature space. The user can place the stored food (such as stored food such as meat food) in the ultrasonic-assisted processing chamber 100, and then automatically or manually start the marinating program of the refrigerator 700 to start marinating the stored food. As described in the background technology section, consumers currently marinate stored food by mixing the marinade and the stored food and placing them directly in the refrigerator for standing, which requires a long marinating time. The ultrasonic-assisted processing chamber 100 of the present invention is provided with at least one first ultrasonic generator 400 on the side of the container upper cover assembly 200 facing the accommodating cavity 600. The ultrasonic wave emitted by the first ultrasonic generator 400 acts on the stored food in the accommodating cavity, pushing the particles in the stored food to vibrate back and forth, accelerating the speed at which the marinade enters the stored food, and realizing rapid marinating without requiring too long a marinating time.

[0051] like Figure 3 As shown, in some embodiments, the container upper cover assembly 200 includes a top cover 210 and a top cover seat 220, and the top cover 210 is sealed and buckled on the top cover seat 220 to form a first interlayer cavity 230 between the top cover 210 and the top cover seat 220. Specifically, in order to facilitate users or maintenance personnel to add interlayer medium into the first interlayer cavity 230, a liquid replenishment port (not shown in the figure) can be opened on the top cover 210 or the top cover seat 220, and after the liquid replenishment is completed, the liquid replenishment port can also be sealed with a plug. The ultrasonic assisted processing chamber 100 of the present invention uses the top cover 210 and the top cover seat 220 to seal and define the first interlayer cavity 230, and fills the first interlayer cavity 230 with an interlayer medium, so that an interlayer medium can be arranged above the accommodating cavity. By utilizing the characteristic that the interlayer medium has a small temperature change rate after absorbing the cold in the low temperature environment, the temperature change rate of the container upper cover assembly 200 can be kept smooth and stable as much as possible, so that the temperature field change in the accommodating cavity 600 tends to be stable, thereby ensuring that the stored food is cooled evenly and the temperature change rate is stable, thereby avoiding the internal texture of the stored food from being destroyed and improving the quality of the stored food.

[0052] In some specific embodiments, the interlayer medium can be a coolant with a large specific heat capacity, such as a coolant gel, preferably a solution or a semi-solid medium; in addition, in order to ensure the sealing between the top cover 210 and the top cover seat 220, the top cover 210 and the top cover seat 220 can also be directly sealed, such as adding sealing strips, performing sealing treatments, and other related processes.

[0053] like Figure 3As shown, in some embodiments, the top cover seat 220 includes a recessed portion 221 that is gradually contracted from top to bottom, and the recessed portion 221 is arranged at the center of the top cover seat 220 for accommodating the interlayer medium. Specifically, the recessed portion 221 is arranged at the center of the top cover seat 220, and the projection area of ​​the recessed portion 221 on the horizontal plane is 0.8-0.95 times the area of ​​the top cover seat 220, for example, 0.8 times, 0.85 times, 0.9 times, 0.95 times, 0.875 times. That is to say, the recessed portion 221 occupies most of the area of ​​the top cover seat 220, providing a sufficiently large heat exchange space and improving the heat exchange efficiency; in addition, the surrounding wall of the recessed portion 221 is configured to gradually contract from top to bottom, that is, the recessed portion 221 is in a shape of being larger at the top and smaller at the bottom, so that it is convenient to use a stamping die to stamp the top cover seat 220 during the production process, which is conducive to mass production.

[0054] In this embodiment, at least one first ultrasonic generator 400 is arranged on the lower surface of the recessed portion 221, and at least one first ultrasonic generator 400 is fixedly arranged at the center of the lower surface of the recessed portion 221. Specifically, at least one first ultrasonic generator 400 covers most of the area of ​​the recessed portion 221. In addition, since at least one first ultrasonic generator 400 is arranged on the lower surface of the recessed portion 221, the interlayer medium can indirectly contact the first ultrasonic generator 400, so the interlayer medium can also absorb the heat generated by the first ultrasonic generator 400 when it is working, and has a heat dissipation effect on the first ultrasonic generator 400, thereby ensuring the reliability of the operation of the first ultrasonic generator 400.

[0055] In some specific embodiments, the number of the first ultrasonic generators 400 may be multiple, and the multiple first ultrasonic generators 400 may be one of an ultrasonic vibrator or an ultrasonic wafer. The multiple first ultrasonic generators 400 may be evenly arranged on the side of the recessed portion 221 facing the accommodating cavity 600, and their specific specifications and quantity may be set according to actual conditions.

[0056] In some embodiments, the container base assembly 300 includes an inner liner 310 and a container shell 320. The inner liner 310 is inserted into the container shell 320 and is sealed with the container shell 320 to form a second interlayer cavity 330, and the second interlayer cavity 330 is filled with an interlayer medium. Specifically, in order to facilitate users or maintenance personnel to add interlayer medium to the second interlayer cavity 330, a liquid replenishment port (not shown in the figure) can be opened on the inner liner 310 or the container shell 320. After the liquid replenishment is completed, the liquid replenishment port can also be sealed with a plug; in addition, in order to ensure the sealing between the inner liner 310 and the container shell 320, the inner liner 310 and the container shell 320 can also be directly sealed, such as adding a sealing strip, performing a sealing process, and other related processes.

[0057] like Figure 4As shown, the surface of the interlayer medium in the second interlayer cavity at least exceeds the bottom of the inner liner, so that the interlayer medium can be used to cool the container base assembly 300 and buffer the freezing rate of the stored food. Specifically, the interlayer medium can be a refrigerant with a large specific heat capacity, such as a refrigerant gel, etc., preferably a solution or a semi-solidified medium. The ultrasonic assisted processing chamber 100 of the present invention uses the inner liner 310 and the container shell 320 to seal and define the second interlayer cavity 330, and fills the interlayer medium in the second interlayer cavity 330, so that the interlayer medium can be arranged below the accommodating cavity and in the left and right directions. By utilizing the characteristic that the interlayer medium has a small temperature change rate after absorbing the cold in the low temperature environment, the temperature change rate of the container base assembly 300 can be kept smooth and stable as much as possible, further ensuring the stability of the temperature field in the accommodating cavity 600, thereby ensuring that the stored food is cooled evenly and the temperature change rate is stable, thereby avoiding the destruction of the internal texture of the stored food, and further improving the quality of the stored food.

[0058] In some embodiments, the interlayer medium is selected to have a solidification temperature between -40°C and 0°C, for example, -40°C, -20°C or 0°C, and the interlayer medium may have a specific heat capacity between 1KJ / (kg·K) and 5KJ / (kg·K), for example, 1KJ / (kg·K), 3KJ / (kg·K) or 5KJ / (kg·K), etc. By using an interlayer medium with a larger specific heat capacity, when the same unit of heat (or cold) is absorbed, the temperature change rate of the container cover assembly 200 and the container base assembly 300 becomes smaller. In this way, after the user starts the freezing program, the temperature change of the container cover assembly 200 and the container base assembly 300 is relatively slow, so that the temperature field change of the accommodating cavity 600 tends to be stable, thereby ensuring that the stored food in the accommodating cavity 600 is cooled evenly and the temperature change rate is stable, thereby avoiding the internal texture of the stored food from being destroyed due to a rapid or unstable temperature drop, thereby improving the quality of the stored food; when the freezing program is abnormal or interrupted, the interlayer medium has a large specific heat capacity, which makes it possible to buffer the temperature change rate regardless of whether the temperature of the low-temperature space is rising or falling, thereby ensuring that the internal texture of the frozen food is not destroyed, thereby improving the quality of the stored food; in addition, the selection of the interlayer medium should also need to consider its dangerousness, flammability, non-toxicity and other properties to meet the use environment of the refrigerator 700.

[0059] In some embodiments, the ultrasonic-assisted processing chamber of the present invention further includes at least one second ultrasonic generator 500, which is disposed below the container base assembly 300 and is used to generate ultrasonic waves, and at least a portion of the ultrasonic waves generated by the second ultrasonic generator 500 are applied to the stored food through the container base assembly 300. Specifically, the number of the second ultrasonic generators 500 can be multiple, and the multiple second ultrasonic generators 500 can be evenly arranged on the bottom of the container base assembly 300 away from the accommodating cavity 600, and the specific specifications and quantity can be set according to actual conditions.

[0060] In some embodiments, at least one second ultrasonic generator 500 is fixed to the bottom of the container base assembly 300, and at least one second ultrasonic generator 500 is arranged at the center of the container base assembly 300. In addition, since at least one second ultrasonic generator 500 is arranged at the bottom of the container base assembly 300, the interlayer medium can indirectly contact the second ultrasonic generator 500, so the interlayer medium can also absorb the heat generated by the first ultrasonic generator 400 when it is working, and has a heat dissipation effect on the first ultrasonic generator 400, thereby ensuring the reliability of the first ultrasonic generator 400. The ultrasonic-assisted processing chamber 100 in this embodiment adopts an interlayer medium between the container base assembly 300 and the second ultrasonic generator 500, which can not only ensure that the temperature change rate of the container base assembly 300 remains smooth and stable, and ensure that the stored food is cooled evenly, but also can utilize the property of the interlayer medium having a large specific heat capacity to absorb the heat of the second ultrasonic generator 500, thereby ensuring the reliability of the second ultrasonic generator 500.

[0061] In some embodiments, the first ultrasonic generator 400 and the second ultrasonic generator 500 are both ultrasonic vibrators or ultrasonic chips. Specifically, there may be multiple first ultrasonic generators 400, and the multiple first ultrasonic generators 400 may be one of ultrasonic vibrators or ultrasonic chips; there may be multiple second ultrasonic generators 500, and the multiple second ultrasonic generators 500 may be one of ultrasonic vibrators or ultrasonic chips.

[0062] In some specific embodiments, the sound intensity of the ultrasonic signal generated by the first ultrasonic generator 400 and the second ultrasonic generator 500 is 0.05 W / cm 2 ~2W / cm 2 , for example 0.05W / cm 2 , 1W / cm 2 or 2W / cm 2 wait.
