Description

Technical Field

[0001] This application relates to the technical field of ultrasonic vibrators, and specifically relates to an ultrasonic vibrator and an ultrasonic system. Background Art

[0002] Since the invention of high-power ultrasonic systems, they have been widely used in industrial fields such as ultrasonic welding, ultrasonic emulsification, and ultrasonic cleaning. While bringing huge economic benefits, they have reduced labor costs and increased productivity, and are an indispensable part of modern industrial design.

[0003] Taking the application of an ultrasonic system in the field of ultrasonic welding technology as an example, the ultrasonic vibrator in the ultrasonic system usually includes three parts: a transducer, a horn, and a welding head. The vibration of the transducer is designed to be amplified and transmitted to the welding head part, outputting a certain amplitude (ranging from dozens of micrometers, which is related to the design frequency of the ultrasonic vibrator). The welding head end with high-frequency vibration and large displacement converts kinetic energy into heat energy of the welded parts through physical contact, thereby increasing the temperature and performing fusion welding in a tiny interaction area.

[0004] From the description of the ultrasonic vibrator, it can be seen that the ultrasonic vibrator is essentially a structure that converts electrical energy into mechanical energy and finally into heat energy. Therefore, ensuring that electrical energy can be efficiently transmitted to the workpiece to be processed is an important indicator for evaluating the efficiency of the ultrasonic vibrator. At the same time, the stability of the ultrasonic vibrator is even more important. There are various common ultrasonic failure modes. For example: 1. Physical damage to the piezoelectric ring of the transducer. 2. The piezoelectric ring fails due to the piezoelectric effect, resulting in the frequency of the ultrasonic vibrator being outside the normal frequency range, and the ultrasonic system cannot lock the operating frequency and fails. Among them, part of the physical damage to the piezoelectric ring of the transducer is also attributed to the increase in the temperature of the piezoelectric ring. The piezoelectric effect failure of the piezoelectric ring may be caused by electrical breakdown of the piezoelectric ring or depolarization due to temperature increase. Therefore, the increase in temperature is a very difficult problem. Summary of the Utility Model

[0043] The present application will be further described in detail below in conjunction with the specific embodiments and the accompanying drawings. Similar elements in different embodiments are denoted by related similar element numbers. In the following embodiments, many detailed descriptions are provided to enable a better understanding of the present application. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification in order to avoid overwhelming the core part of the present application with excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the descriptions in the specification and the general technical knowledge in the art.

[0044] In addition, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can also be reordered or adjusted in a manner obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for clearly describing a certain embodiment and do not mean that they are the necessary sequences, unless it is stated otherwise that a certain sequence must be followed.

[0045] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequential or technical meaning. The terms "connection" and "coupling" used in the present application, unless otherwise specified, both include direct and indirect connection (coupling).

[0046] Please refer to Figures 1 - 12 , in an embodiment of the present application, an ultrasonic oscillator is provided, including: a transducer 10, a horn 20, an auxiliary mounting body 30, a refrigerating member 40, and a temperature reduction structure 50. A piezoelectric ring 11 is fixed on the transducer 10. One end of the horn 20 is connected to the transducer 10, and the other end of the horn 20 is used to connect to an ultrasonic tool head 100. The auxiliary mounting body 30 is fixed in the nodal region of the horn 20. The auxiliary mounting body 30 and the horn 20 can be an integral structure or a detachable structure, as long as the auxiliary mounting body 30 can be fixed in the nodal region of the horn 20. The refrigerating member 40 (such as a thermoelectric cooler) has opposite cold end 41 and hot end 42, and the cold end 41 is in contact with the auxiliary mounting body 30. The temperature reduction structure 50 is adjacent to the hot end 42, and the temperature reduction structure 50 is used to reduce the temperature of the hot end 42.

[0047] With the above ultrasonic vibrator, a refrigerating element 40 is arranged on the auxiliary mounting body 30. The cold end 41 of the refrigerating element 40 is in contact with the auxiliary mounting body 30, and the hot end 42 of the refrigerating element 40 is in contact with the temperature reduction structure 50. Through the heat conduction between the cold end 41 and the hot end 42 of the refrigerating element 40, the temperature difference at the auxiliary mounting body 30 is increased. The greater the temperature difference, the greater the driving force of the heat flow (the driving force of the heat flow = temperature gradient * thermal conductivity at a certain distance), which facilitates the rapid temperature reduction at the auxiliary mounting body 30, thereby reducing the temperature at the piezoelectric ring 11 of the transducer 10, ensuring the effective operation of the ultrasonic vibrator, and prolonging the service life of the ultrasonic vibrator. The temperature of the hot end 42 of the refrigerating element 40 is relatively higher. Through the arranged temperature reduction structure 50, the hot end 42 can be cooled in time (that is, the heat of the hot end 42 is conducted out), ensuring the continuous effectiveness of the temperature reduction effect on the piezoelectric ring 11. The nodal region of the horn 20 does not vibrate, so the auxiliary mounting body 30, the refrigerating element 40, and the temperature reduction structure 50 arranged at this position do not vibrate either. Therefore, it does not affect the energy utilization rate of the ultrasonic vibrator, and at the same time, it does not have an adverse effect on the frequency of the ultrasonic vibrator.

[0048] If the structure designed to reduce the temperature at the piezoelectric ring 11 is inappropriate, it is likely to have an adverse effect on the frequency of the ultrasonic vibrator, thereby increasing the control difficulty of the ultrasonic system circuit. However, for the ultrasonic vibrator designed in this application, there is no such concern.

[0049] Please refer to Figure 7 , the ultrasonic vibrator further includes a heat conduction layer 60. A heat conduction layer 60 is arranged between the cold end 41 and the auxiliary mounting body 30, and / or between the hot end 42 and the temperature reduction structure 50. Preferably, a heat conduction layer 60 is arranged between the cold end 41 and the auxiliary mounting body 30, and between the hot end 42 and the temperature reduction structure 50. The heat conduction layer 60 is made of a material that can conduct heat, such as thermal grease, which can play a role in heat conduction, facilitating the rapid transfer of heat, and thus rapid temperature reduction. When the heat conduction layer 60 is made of thermal grease, the heat conduction layer 60 can withstand a certain stress and strain, facilitating the installation and fixing structure.

[0050] Specifically, multiple refrigerating elements 40 are arranged. The multiple refrigerating elements 40 are arranged in different regions of the auxiliary mounting body 30, and / or the multiple refrigerating elements 40 are stacked and arranged in the same region of the auxiliary mounting body 30. When the multiple refrigerating elements 40 are stacked, a heat conduction layer 60 is arranged between adjacent refrigerating elements 40, and one side of the heat conduction layer 60 between adjacent refrigerating elements 40 corresponds to the cold end 41, and the other side corresponds to the hot end 42. When the multiple refrigerating elements 40 are stacked, a lower temperature region can be generated at the auxiliary mounting body 30, providing a greater refrigerating driving force for the ultrasonic vibrator.

[0051] Specifically, multiple cooling structures 50 are provided. When multiple cooling elements 40 are respectively disposed in different regions of the auxiliary mounting body 30, the cooling structures 50 and the cooling elements 40 are arranged in a one-to-one correspondence. When multiple cooling elements 40 are stacked in the same region of the auxiliary mounting body 30, the multiple cooling elements 40 share one cooling structure 50. At this time, the hot end 42 of the cooling element 40 farthest from the auxiliary mounting body 30 is adjacent to the cooling structure 50. More preferably, when multiple cooling elements 40 are stacked, the number of stacked cooling elements 40 is 2 to 3. For example, as Figure 7 shown, two cooling elements 40 are stacked in the same region of the auxiliary mounting body 30.

[0052] Please refer to Figures 1 - 7 . The ultrasonic vibrator further includes a mounting structure 70. The mounting structure 70 is used to fix the cooling structure 50 to the auxiliary mounting body 30 and make the cooling structure 50 adjacent to the cooling element 40.

[0053] Specifically, please refer to Figures 1 - 2 . In one embodiment, the auxiliary mounting body 30 is a rod-shaped structure. The rod-shaped structure is fixedly disposed across the nodal region of the horn 20 to form a heat conduction path. The axial direction of the rod-shaped structure is perpendicular to the axial direction of the horn 20. First assembly planes 31 are respectively provided at both ends of the rod-shaped structure. The first assembly planes 31 are perpendicular to the axis of the horn 20, and the cold end 41 is in contact with the first assembly plane 31. The mounting structure 70 includes a first mounting member 71 and a second mounting member 72. The first mounting member 71 includes a mating portion 711 and a docking portion 712 connected to each other. The mating portion 711 has a mating groove that mates with the cooling structure 50, and the docking portion 712 is connected to the second mounting member 72. The second mounting member 72 is plate-shaped. The second mounting member 72 is sleeved on the horn 2 and is connected to the docking portion 712. The first mounting member 71 and the second mounting member 72 clamp and fix the cooling element 40 and the cooling structure 50 to the first assembly plane 31. Among them, the first mounting member 71 is generally in a U-shape, and the docking portions 712 are symmetrically arranged on both sides of the mating portion 711. The cooling element 40 is specifically a thermoelectric cooler. The first assembly plane 31 is provided on the rod-shaped auxiliary mounting body 30 to facilitate the installation and fixation of the cooling element 40.

[0054] The auxiliary installation body 30 of the rod-shaped structure is similar to a plug rod. At this time, the auxiliary installation body 30 can be an integral structure with the horn 20, or a through hole is opened in the node area of the horn 20, and the axis of the through hole is perpendicular to the axis of the horn 20. The auxiliary installation body 30 passes through the through hole and is detachably connected to the horn 20. Specifically, the auxiliary installation body 30 can be a prismatic rod-shaped structure or a cylindrical rod-shaped structure. For the auxiliary installation body 30 with a prismatic rod-shaped structure, it has a first assembly plane 31 by itself without additional setting. For the auxiliary installation body 30 with a cylindrical rod-shaped structure, first assembly planes 31 need to be separately opened at both axial ends of the auxiliary installation body 30. One first assembly plane 31 or two first assembly planes 31 can be opened at the same end of the auxiliary installation body 30. When one first assembly plane 31 is opened at each end of the auxiliary installation body 30, as Figure 2 shown, the first assembly planes 31 at both ends of the auxiliary installation body 30 can be located on the same side of the auxiliary installation body 30, or in other embodiments, the first assembly planes 31 at both ends of the auxiliary installation body 30 are located on different sides of the auxiliary installation body 30. The more first assembly planes 31 are opened on the auxiliary installation body 30, the more refrigeration parts 40 can be placed (at least one refrigeration part 40 can be placed on one first assembly plane 31), which will create a larger refrigeration contact surface and facilitate more sufficient and rapid cooling of the transducer 10 (piezoelectric ring 11).

[0055] Specifically, in the embodiment of the present application, Figure 2Taking the auxiliary mounting body 30 shown as an example, first mounting planes 31 are symmetrically provided at both ends on the same side of the auxiliary mounting body 30. Refrigerating elements 40 are placed on the first mounting planes 31 at both ends of the auxiliary mounting body 30, and the heat ends 42 of the refrigerating elements 40 are all placed with cooling structures 50. The first mounting member 71 in a substantially "J" shape covers the cooling structure 50 and plays a fixing role for the cooling structure 50. For example, the first mounting member 71 abuts against the cooling structure 50 to press and fix the cooling structure 50 on the heat end 42 of the refrigerating element 40. The first mounting plane 31 is perpendicular to the axis of the horn 20. The second mounting member 72 is in the shape of a disc plate, sleeved on the horn 20, and connected to one end of the first mounting member 71 close to the auxiliary mounting body 30, for example, by screw connection. At this time, one second mounting member 72 can correspondingly connect two first mounting members 71, which is convenient for realizing the rapid assembly of the mounting structure 70. More specifically, a first mounting hole 721 is provided on the second mounting member 72 to facilitate the second mounting member 72 to be sleeved on the horn 20, wherein the aperture of the first mounting hole 721 is larger than the outer diameter of the horn 20 to prevent the second mounting member 72 from contacting the horn 20 and affecting the frequency and / or cooling of the ultrasonic vibrator. A first docking groove 722 is also provided on the second mounting member 72, and the first docking groove 722 is in concave-convex fit with the outer shape of the rod-shaped auxiliary mounting body 30, which can not only facilitate the rapid assembly of the first mounting member 71 and the second mounting member 72, but also make the structural design of the auxiliary mounting body 30 more compact here. In other embodiments, the first mounting member 71 and the second mounting member 72 can also be in a one-to-one correspondence relationship. At this time, the perpendicular relationship between the first mounting plane 31 and the axial direction of the horn 20 does not need to be limited.

[0056] Specifically, please refer to Figures 3 - 5 , in one embodiment, the auxiliary mounting body 30 is a flange 32, and the refrigerating element 40 is arranged on at least one end face of the flange 32. The mounting structure 70 includes a mating portion 711 and a docking portion 712 connected to each other. The mating portion 711 has a mating groove, and the mating groove mates with the cooling structure 50. The mating portion 711 is connected to the end face of the flange 32 (for example, by screws), and the mounting structure 70 clamps and fixes the refrigerating element 40 and the cooling structure 50 to the end face of the flange 32. Among them, the mounting structure 70 is substantially in a "J" shape, and docking portions 712 are symmetrically arranged on both sides of the mating portion 711. The docking portions 712 are, for example, as Figure 5 the mounting plates 74 shown in

[0057] More specifically, the flange 32 has two opposite end faces along the axial direction of the horn 20, both of which can be used as the mounting surfaces for the refrigerating elements 40, and multiple refrigerating elements 40 can also be placed on the end face of the same flange 32. The mounting structure 70 and the cooling structure 50 are in one-to-one correspondence, as Figure 3As shown in the figure, along the axial direction of the horn 20, one end of the approximately U-shaped mounting structure 70 is clamped with the cooling structure 50, and the other end is connected to the flange 32. The approximately U-shaped mounting structure 70 can not only ensure the fixing effect of the cooling structure 50, but also reduce the contact area with the cooling structure 50 to ensure the cooling effect of the cooling structure 50. In order to make the cooling structure 50 have a better cooling or heat dissipation effect, a heat dissipation opening 73 is provided at one end of the mounting structure 70 away from the flange 32, further reducing the contact area between the mounting structure 70 and the cooling structure 50.

[0058] Preferably, in the embodiment of the present application, a positioning groove (not shown) is provided on the end face of the flange 32 to ensure that the refrigerating element 40 can be placed on the end face of the flange 32 according to the preset position, which is convenient for the mass production of the ultrasonic vibrator and ensures the product consistency of the ultrasonic vibrators in the same batch. When multiple refrigerating elements 40 are placed on the same end face of the flange 32, the multiple refrigerating elements 40 are distributed in a circumferential array along the flange 32 to ensure the cooling consistency of the piezoelectric ring 11 in the transducer 10. Among them, most of the shapes of the flange 32 are disc-shaped. Therefore, in the embodiment of the present application, taking the disc-shaped flange 32 as an example, at this time, in order to improve the area utilization rate of the refrigerating element 40 placed on the end face of the flange 32, the refrigerating element 40 is a fan-shaped thin sheet. In other embodiments, the refrigerating element 40 can also be other shapes, such as rectangular, square, circular and other shapes that are convenient for processing. At this time, in order to ensure the fitting area between the end face of the flange 32 and the refrigerating element 40 (including the case of indirect fitting between the refrigerating element 40 and the flange 32 when designing the heat conduction layer 60), the shape of the flange 32 can be adjusted adaptively. For example, when the refrigerating element 40 is a rectangular sheet, a part of the refrigerating element 40 is attached to the end face of the flange 32, and the other part extends to the outside of the flange 32. At this time, the flange 32 can also be designed with a part adapted to the shape of the refrigerating element 40 extending outside the flange 32 to ensure that the entire refrigerating element 40 and the flange 32 can be attached.

[0059] Preferably, in the embodiment of the present application, please refer to Figures 3 - 5 , the radial diameter of the flange 32 is 2 cm - 10 cm larger than the radial diameter of the horn 20. At this time, the flange 32 has enough installation area to place the refrigerating element 40, thereby ensuring that the ultrasonic vibrator has enough cooling area to better cool the piezoelectric ring 11 in the transducer 10.

[0060] Specifically, please refer to Figures 6 - 7 , in one embodiment, the auxiliary mounting body 30 includes a flange 32 and a column 33. The column 33 has an installation cavity that penetrates along the axial direction. The inner ring of the flange 32 is fixed to the node area of the horn 20, and the outer ring of the flange 32 is fixed to the end of the column 33 (such as as Figure 8 shown), or the outer ring of the flange 32 is fixed in the installation cavity of the column 33 (such as asFigure 9 As shown). At least one second assembly plane 331 is provided on the outer wall of the column body 33, and the cold end 41 is in contact with the second assembly plane 331. The installation structure 70 includes an installation main board 75 and a clamping column 76. The installation main board 75 is sleeved on the horn 20. The surface of the installation main board 75 facing the transducer 10 is a bearing surface 751, and the bearing surface 751 is used to fix the temperature reduction structure 50 at the auxiliary installation body 30. One end of the clamping column 76 is clamped with the end surface of the column body 33 away from the installation main board 75, and the other end of the clamping column 76 is fixed on the bearing surface 751.

[0061] When the auxiliary installation body 30 includes a flange 32 and a column body 33, the flange 32 acts as a connection between the column body 33 and the horn 20 at this time. Since the column body 33 can provide enough installation area for the refrigerating member 40, the radial dimension of the flange 32 does not need to be required at this time, and the radial dimension of the flange 32 can be designed to be smaller, which is convenient for the miniaturization design of the ultrasonic vibrator. The column body 33 is, for example, Figures 6 - 7 As shown in the prism shape, there are multiple planes on the outer peripheral surface of the column body 33 itself to act as the second assembly plane 331. The column body 33 can also be Figure 10 As shown in the cylindrical shape. At this time, according to the number of refrigerating members 40, the corresponding number of second assembly planes 331 are opened on the column body 33. For example, if three refrigerating members 40 are arranged in an array on the outer periphery of the column body 33, three second assembly planes 331 can be opened on the outer periphery of the column body 33. The structure of the column body 33 is convenient for expanding the installation area of the refrigerating member 40. When the installation area of the refrigerating member 40 is large enough, the area of the second assembly plane 331 can be increased by extending the axial length of the column body 33.

[0062] For the convenience of installation and use, the clamping column 76 and the installation main board 75 are detachable structures. The clamping column 76 is an L-shaped clamping column. One end of the clamping column 76 is clamped with the end surface of the column body 33 away from the installation main board 75, and the other end of the clamping column 76 can be detachably fixed on the bearing surface 751 by screws.

[0063] As Figure 7 Shown, a second assembly hole 752 is opened on the installation main board 75 to facilitate the installation main board 75 to be sleeved on the horn 20, and the aperture of the second assembly hole 752 is larger than the outer diameter of the horn 20 to prevent the installation main board 75 from contacting the horn 20 and affecting the frequency of the ultrasonic vibrator or the energy utilization rate of the ultrasonic vibrator. A second docking groove 753 adapted to the outer peripheral shape of the column body 33 is opened on the side of the installation main board 75 facing the transducer 10 to ensure the stability of the connection between the installation structure 70 and the column body 33, and further provide a sufficiently stable bearing surface 751 for the temperature reduction structure 50 at the refrigerating member 40. Among them, the temperature reduction structure 50 can be fixed on the bearing surface 751 by screws, clamping or welding, etc.

[0064] Preferably, the ultrasonic oscillator further includes a sleeve 80 for sleeving the refrigerating member 40 and the temperature reduction structure 50 inside the sleeve 80. Through the sleeve 80, the refrigerating member 40 and the temperature reduction structure 50 inside it can be protected from being blocked. In terms of appearance, the ultrasonic oscillator can look more beautiful. At the same time, the inner wall of the sleeve 80 can also be in contact with the temperature reduction structure 50 to provide a certain supporting effect for the temperature reduction structure 50.

[0065] Please refer to Figures 3 - 5 , when the auxiliary mounting body 30 only includes the flange 32, the sleeve 80 is sleeved outside the horn 20, and the refrigerating member 40 and the temperature reduction structure 50 thereon are sleeved inside the sleeve 80. The end of the sleeve 80 is fixed on the flange 32. For example, a groove corresponding to the wall thickness of the sleeve 80 is opened on the flange 32, and the sleeve 80 is clamped to the flange 32 through the groove. In order to better exert the temperature reduction effect, an avoidance opening 81 can also be opened at the position corresponding to the sleeve 80 and the temperature reduction structure 50, so that the heat of the temperature reduction structure 50 can be dissipated in time.

[0066] Please refer to Figures 6 - 7 , when the auxiliary mounting body 30 includes the flange 32 and the cylinder 33, the sleeve 80 is sleeved outside the cylinder 33, and the refrigerating member 40 and the temperature reduction structure 50 are placed in the space between the sleeve 80 and the cylinder 33. The sleeve 80 is fixed on the mounting structure 70 at this time. For example, the sleeve 80 is fixed on the clamping column 76 of the mounting structure 70 by screws. Similarly, in order to better exert the temperature reduction effect, an avoidance opening 81 can also be opened at the position corresponding to the sleeve 80 and the temperature reduction structure 50 at this time, so that the heat of the temperature reduction structure 50 can be dissipated in time.

[0067] Please refer to Figures 3 - 7 , the thickness of the flange 32 is 1 mm - 10 mm. The thickness of the flange 32 can be the same as a whole, that is, the flange 32 only has one thickness. For example, the overall thickness of the flange 32 is 5 mm. Different regions of the flange 32 can also have different thicknesses. For example, half of the flange 32 has a thickness of 1 mm, and the other half of the flange 32 has a thickness of 10 mm. When the flange 32 has a variety of thickness combinations, it is also convenient for the design of the ultrasonic oscillator. The thickness of the flange 32 cannot be too thin, which will affect the design, nor can it be too thick, which will affect heat conduction. When the thickness of the flange 32 is 1 mm - 10 mm, the requirements in terms of design and heat conduction can be better balanced. Preferably, the thickness of the flange 32 is 2 mm - 4 mm.

[0068] Please refer to Figure 1, the ultrasonic vibrator further includes a temperature control power supply 90. The refrigeration component 40 is electrically connected to the temperature control power supply 90. The temperature control power supply 90 is used to adjust the heat flow of the refrigeration component 40 by changing the current to perform temperature control. Under the action of the temperature control power supply 90, the function of the refrigeration component 40 can be better exerted, facilitating the formation of an appropriate temperature difference between the cold end 41 and the hot end 42 of the refrigeration component 40, and better ensuring the cooling effect.

[0069] Please refer to Figure 9 , along the axial direction of the horn 20, a first liquid infusion channel 21 is opened in the horn 20. A second liquid infusion channel 34 is opened in the auxiliary mounting body 30, and the first liquid infusion channel 21 is communicated with the second liquid infusion channel 34. When the auxiliary mounting body 30 is a rod-shaped structure, the second liquid infusion channel 34 communicating with the outside can be opened along the axial direction of the auxiliary mounting body 30. When the auxiliary mounting body 30 includes a flange 32 (and a cylinder 33), the second liquid infusion channel 34 communicating with the outside can be opened in the radial direction of the flange 32. The ultrasonic vibrator can be used in the medical field, for example, using the ultrasonic vibrator to treat cataracts. By opening the first liquid infusion channel 21 and the second liquid infusion channel 34, the ultrasonic vibrator has the function of adding liquid medicine, better exerting the treatment effect of the ultrasonic vibrator. At the same time, due to the cooling effect exerted by the cooperation of the refrigeration component 40 and the cooling structure 50, when the ultrasonic vibrator is used for treating the eyes, the appropriate temperature of the liquid medicine dropped into the eyes can be guaranteed, increasing the use safety of the ultrasonic vibrator.

[0070] Please refer to Figures 1 - 7 , the cooling structure 50 is at least one of a liquid cooling component 50a, a heat dissipation component 50b, and a fan 50c. The liquid cooling component 50a is a hollow shell containing a liquid storage cavity 50a1. The hollow shell is provided with a liquid inlet 50a2 and a liquid outlet 50a3 both communicating with the liquid storage cavity 50a1. The liquid cooling component 50a is used to convey a heat-conducting liquid into the liquid storage cavity 50a1 through the liquid inlet 50a2 and take away the heat-conducting liquid that has absorbed heat through the liquid outlet 50a3 to cool the refrigeration component 40. The heat dissipation component 50b contains a plurality of heat dissipation fins.

[0071] Specifically, the cooling structure 50 is a liquid cooling component 50a, for example Figures 1 - 2As shown, one end face of the temperature reduction structure 50 is in contact with the hot end 42 of the refrigerating member 40 (indirectly in contact when the heat conduction layer 60 is provided). The heat conduction liquid flowing in the liquid temperature reduction member 50a takes away the temperature of the hot end 42 of the refrigerating member 40 to achieve the temperature reduction effect. The liquid inlet 50a2 and the liquid outlet 50a3 of the liquid temperature reduction member 50a can both be connected to a water pump, and the water pump serves as the power structure for the flow of the liquid in the liquid storage cavity 50a1. The flow rate of the heat conduction liquid in the liquid storage cavity 50a1 can be controlled by the water pump. Different temperature reduction effects depend on different flow rates of the heat conduction liquid or the current passing through the refrigerating member 40. Specifically, the flow rate of the heat conduction liquid and / or the magnitude of the current on the refrigerating member 40 can be controlled according to actual needs. The heat conduction liquid is specifically a high heat-conducting liquid substance, such as water, refrigerant, etc. Preferably, as Figure 11 As shown, a partition plate 50a4 is provided in the liquid storage cavity 50a1 between the liquid inlet 50a2 and the liquid outlet 50a3. One end of the partition plate 50a4 close to the liquid inlet 50a2 or the liquid outlet 50a3 is connected to the inner wall of the hollow housing containing the liquid storage cavity 50a1, and the end of the partition plate 50a4 far from the liquid inlet 50a2 or the liquid outlet 50a3 is spaced from the inner wall of the hollow housing containing the liquid storage cavity 50a1. The partition plate 50a4 is used to divide the flow of the heat conduction liquid in the liquid storage cavity 50a1, so that the heat conduction liquid forms a flow direction from the liquid inlet 50a2 to the side of the liquid outlet 50a3 in the liquid storage cavity 50a1. Under the action of the partition plate 50a4, the heat conduction liquid in the liquid storage cavity 50a1 forms a directional flow, which is convenient for more efficiently exerting the temperature reduction effect of the heat conduction liquid. Specifically, the temperature reduction structure 50 is a heat dissipation member 50b containing a plurality of heat dissipation fins, such as Figure 4 As shown. The heat dissipation member 50b is in contact with the hot end 42 of the refrigerating member 40, and the temperature of the hot end 42 is dissipated and reduced by the plurality of heat dissipation fins on the heat dissipation member 50b. Specifically, the temperature reduction structure 50 is a fan 50c. By directly arranging the fan 50c at the hot end 42 of the refrigerating member 40 and connecting the fan 50c to a power source, starting the power source can take away the temperature of the hot end 42 of the refrigerating member 40 through the airflow generated by the fan 50c. Specifically, the temperature reduction structure 50 includes a liquid temperature reduction member 50a, a heat dissipation member 50b, and a fan 50c, such as Figures 6 - 7As shown in the figure, only the liquid cooling element 50a is provided on the cooling element 40 on one side, and both the heat dissipation element 50b and the fan 50c are provided on the cooling element 40 on the other side. The fan 50c is arranged at multiple fins of the heat dissipation element 50b, and the heat dissipation element 50b and the fan 50c cooperate to cool the hot end 42 of the cooling element 40 together. From the above description, it can be seen that the cooling structure 50 in the ultrasonic vibrator of the present application can be one, two, or three of the three cooling structures 50: the liquid cooling element 50a, the heat dissipation element 50b, and the fan 50c. When the cooling structure 50 includes multiple types, different cooling structures 50 can be used separately or in a stacked combination. There are multiple specific usage methods of the cooling structure 50, which can be specifically selected or combined according to actual cooling requirements.

[0072] Please refer to Figures 1 - 7 , the ultrasonic vibrator further includes an ultrasonic tool head 100. One end of the horn 20 is connected to the transducer 10, and the other end of the horn 20 is connected to the ultrasonic tool head 100. The first connecting portion 22 and the second connecting portion 23 are respectively arranged at the two axial ends of the horn 20. For example, as Figure 12 shown, a hole-shaped first connecting portion 22 is formed at one end of the horn 20 for easy connection to the transducer 10, and a threaded rod-shaped second connecting portion 23 is formed at the other end for easy detachable connection to the ultrasonic tool head 100. In other embodiments, the ultrasonic tool head 100 can also be an integral structure with the horn 20, or the ultrasonic tool head 100 is not provided, and the function of the ultrasonic tool head 100 is taken into account by the horn 20. For example, as Figures 8 - 9 shown. The ultrasonic vibrator designed in the embodiment of the present application can be used in multiple fields, such as ultrasonic welding, ultrasonic emulsification, ultrasonic cleaning, etc. The corresponding ultrasonic tool head 100 can be at least one of an ultrasonic welding head, an ultrasonic emulsification head, an ultrasonic cleaning head, or an ultrasonic scalpel. The ultrasonic tool head 100 and the horn 20 are detachably connected, which is convenient for replacing different types of ultrasonic tool heads 100 or ultrasonic tool heads 100 of the same type but different models, increasing the practicability of the ultrasonic vibrator designed in the present application, or reducing the use cost of the ultrasonic vibrator in multiple scenarios.

[0073] The materials of the horn 20 and the ultrasonic tool head 100 in the ultrasonic vibrator can be the same or different. The auxiliary mounting body 30 in the node area divides the horn 20 into two parts along the axial direction. The shapes of the two parts of the horn 20 in the axial direction can be the same or different, and can be specifically and flexibly selected according to actual needs. The present application does not specifically limit these features.

[0074] Among the common failure modes of ultrasonic vibrators, there is also failure caused by the damage of the ultrasonic tool head 100. The ultrasonic tool head 100 is a vulnerable part and is prone to damage when the temperature is too high. Taking the ultrasonic welding head as an example, the ultrasonic welding head is prone to physical wear due to high temperature during use, and finally fails. By using the ultrasonic vibrator designed in this application, since the refrigerating member 40 and the temperature reduction structure 50 are added to the auxiliary mounting body 30 in the node region of the horn 20, it can not only cool the piezoelectric ring 11 in the transducer 10, but also cool the ultrasonic tool head 100, ensuring the working conditions of the ultrasonic tool head 100, or extending the service life of the ultrasonic tool head 100, better avoiding the failure of the ultrasonic vibrator and ensuring the effective use of the ultrasonic vibrator.

[0075] Please refer to Figure 13 , when the temperature reduction structure 50 is added to the ultrasonic vibrator of this application, the working state of the ultrasonic vibrator is as shown by the dots in Figure 13 . When the temperature reduction structure 50 is not added to the ultrasonic vibrator of this application, the working state of the ultrasonic vibrator is as shown by the square frame in Figure 13 . When the ultrasonic vibrator is working, the temperature will increase and the frequency will decrease over time. When the temperature reduction structure 50 is added to the ultrasonic vibrator, the degree of temperature increase of the ultrasonic vibrator is relatively small, and the frequency decrease is not much, which is convenient for control. Because ultrasonic generally tracks frequency, a corresponding frequency tracking system is set. If the frequency span is large, the software algorithm of the frequency tracking system will become complex, which is not conducive to the control of the ultrasonic vibrator. When the temperature changes, the frequency of the entire ultrasonic vibrator will also change, and the impedance and resistance will also change. After the temperature reduction structure 50 is added to this application, as the use time increases, the degree of frequency reduction will be relatively small, and the frequency will be relatively more stable. In this way, the impedance will also be more stable, and the relationship coefficient between the current voltage and the output power will not change too much, which is convenient for controlling the end power at the ultrasonic tool head 100.

[0076] By using the ultrasonic vibrator in the above embodiments designed in this application, the refrigerating member 40 and the temperature reduction structure 50 can timely take away the heat generated by the piezoelectric ring 11 in the transducer 10 due to electrical loss and mechanical internal loss, effectively reducing the heat generation degree of the transducer 10 during use. The refrigerating member 40 and the temperature reduction structure 50 can also timely take away the heat generated in the ultrasonic tool head 100, effectively reducing the heat generation degree of the ultrasonic tool head 100 during use. It effectively protects the structure of the ultrasonic vibrator and extends the service life of the ultrasonic vibrator. The designed ultrasonic vibrator structure can effectively ensure the frequency stability during the use of the ultrasonic vibrator. The designed ultrasonic vibrator can be applied not only to multiple fields, but also to a wider range of powers, such as a power of several watts or a power of kilowatts, with high practicability.

[0077] An ultrasonic system includes an ultrasonic power supply and the above ultrasonic vibrator. The ultrasonic power supply is electrically connected to the ultrasonic vibrator. The ultrasonic power supply is used to send ultrasonic signals to the ultrasonic vibrator, such as sending high-frequency and high-power ultrasonic signals. After the ultrasonic signal is input into the transducer 10, the transducer 10 can be driven to vibrate. The ultrasonic system includes the ultrasonic vibrator in the above embodiment, so it also has the advantages of the above ultrasonic vibrator, which will not be elaborated here.

[0078] The above ultrasonic vibrator designed in this application is specifically illustrated by the following embodiments:

[0079] Embodiment 1

[0080] Please refer to Figures 1 - 2 , an ultrasonic vibrator, including: a transducer 10, a horn 20, an auxiliary mounting body 30, a refrigerating member 40, a temperature reduction structure 50, a heat conduction layer 60, a mounting structure 70, and a temperature control power supply 90.

[0081] A piezoelectric ring 11 is fixed on the transducer 10.

[0082] One end of the horn 20 is connected to the transducer 10, and the other end of the horn 20 is connected to the ultrasonic tool head 100. The ultrasonic tool head 100 is an ultrasonic welding head, an ultrasonic emulsifying head, an ultrasonic cleaning head, or an ultrasonic scalpel.

[0083] The auxiliary mounting body 30 is a rod-shaped structure, and the rod-shaped structure is fixedly arranged across the node area of the horn 20. First assembly planes 31 are respectively arranged at both ends of the rod-shaped structure, and the first assembly planes 31 are perpendicular to the axis of the horn 20.

[0084] A refrigerating member 40 is placed on each first assembly plane 31 of the auxiliary mounting body 30. The refrigerating member 40 has opposite cold ends 41 and hot ends 42, and the cold end 41 is in contact with the first assembly plane 31.

[0085] A temperature reduction structure 50 is placed at the hot end 42 of each refrigerating member 40. The temperature reduction structure 50 is specifically a liquid temperature reduction member 50a. The liquid temperature reduction member 50a is a hollow shell containing a liquid storage cavity 50a1. The hollow shell is provided with a liquid inlet 50a2 and a liquid outlet 50a3 both communicating with the liquid storage cavity 50a1. The liquid temperature reduction member 50a is used to convey a heat-conducting liquid into the liquid storage cavity 50a1 through the liquid inlet 50a2 and take away the heat-conducting liquid that absorbs heat through the liquid outlet 50a3, so as to cool the refrigerating member 40. A partition plate 50a4 is arranged in the liquid storage cavity 50a1 between the liquid inlet 50a2 and the liquid outlet 50a3. The partition plate 50a4 is used to shunt the heat-conducting liquid in the liquid storage cavity 50a1, so as to facilitate the heat-conducting liquid to form a flow direction from the liquid inlet 50a2 to the side of the liquid outlet 50a3 in the liquid storage cavity 50a1. The liquid temperature reduction member 50a further includes a water pump, and the water pump is respectively connected to the liquid inlet 50a2 and the liquid outlet 50a3.

[0086] A heat conducting layer 60 is provided between the cold end 41 and the first assembly plane 31, and between the hot end 42 and the liquid cooling member 50a.

[0087] The installation structure 70 is used to fix the cooling structure 50 at the refrigerating member 40. The installation structure 70 includes a first installation member 71 and a second installation member 72. The first installation member 71 is generally in a U-shape, and the second installation member 72 is in a disc shape. The second installation member 72 is sleeved on the horn 20 and connected to one end of the first installation member 71, and the other end of the first installation member 71 contacts the cooling structure 50. At this time, one second installation member 72 corresponds to two first installation members 71. Among them, the installation structure 70 is a high-strength thermosetting plastic, which on the one hand avoids the risk of electric shock when contacting the auxiliary installation body 30 (such as being made of metal), and on the other hand, reduces the heat conduction degree when the installation structure 70 contacts the auxiliary installation body 30 to ensure the cooling effect.

[0088] The refrigerating member 40 is electrically connected to the temperature control power supply 90, and the temperature control power supply 90 is used to control the temperature by adjusting the current to change the heat flow of the refrigerating member 40.

[0089] The ultrasonic vibrator in this embodiment has a compact structure and is suitable for applications in low-power scenarios, such as ultrasonic scalers.

[0090] Embodiment 2

[0091] The difference between the ultrasonic vibrator in this embodiment and the ultrasonic vibrator in Embodiment 1 is that a first liquid infusion channel 21 is opened axially in the horn 20, and the first liquid infusion channel 21 can extend to the end of the ultrasonic tool head 100 far from the horn 20. A second liquid infusion channel 34 is opened axially in the auxiliary installation body 30, and the second liquid infusion channel 34 is communicated with the first liquid infusion channel 21 to facilitate liquid infusion when using the ultrasonic vibrator. For example, when using the ultrasonic vibrator for eye treatment, liquid medicine can be input into the eye through the first liquid infusion channel 21 and the second liquid infusion channel 34. The rest of the structure is the same as that in Embodiment 1, so it will not be elaborated here.

The other end of the horn 20 is connected to the ultrasonic tool head 100. The ultrasonic tool head 100 is an ultrasonic welding head, an ultrasonic emulsifying head, an ultrasonic cleaning head, or an ultrasonic scalpel.

[0096] The auxiliary mounting body 30 is a flange 32, which is fixed to the nodal region of the horn 20. Three refrigerating elements 40 are arranged on the end face of the flange 32 close to the transducer 10, and the three refrigerating elements 40 are arranged in a circumferential array along the end face of the flange 32. The refrigerating element 40 has opposite cold ends 41 and hot ends 42, and the cold end 41 is in contact with the end face of the flange 32.

[0097] The temperature reduction structure 50 is arranged in one-to-one correspondence with the refrigerating element 40.

The temperature reduction structure 50 is at least one of a liquid cooling element 50a, a heat sink 50b, and a fan 50c. The liquid cooling element 50a is a hollow shell containing a liquid storage cavity 50a1. The hollow shell is provided with a liquid inlet 50a2 and a liquid outlet 50a3 that are both connected to the liquid storage cavity 50a1. The liquid cooling element 50a is used to transport a heat-conducting liquid into the liquid storage cavity 50a1 through the liquid inlet 50a2, and take away the heat-conducting liquid that has absorbed heat through the liquid outlet 50a3, so as to play a role in cooling the refrigerating element 40. A partition plate 50a4 is arranged in the liquid storage cavity 50a1 between the liquid inlet 50a2 and the liquid outlet 50a3. The partition plate 50a4 is used to shunt the heat-conducting liquid in the liquid storage cavity 50a1, so as to facilitate the heat-conducting liquid to form a flow direction from the liquid inlet 50a2 to the side of the liquid outlet 50a3 in the liquid storage cavity 50a1. The heat sink 50b contains a plurality of heat dissipation fins. Specifically, for example, Figure 3 As shown, one of the three refrigerating elements 40 is correspondingly provided with a liquid cooling element 50a, and one is correspondingly provided with a heat sink 50b.

[0098] A heat-conducting layer 60 is arranged between the cold end 41 and the flange 32, and between the hot end 42 and the temperature reduction structure 50.

One end of the mounting structure 70 is connected to the end face of the flange 32, and the other end of the mounting structure 70 is in contact with the temperature reduction structure 50. Among them, if the mounting structure 70 is made of a metal material, in order to avoid the risk of electric shock when contacting the auxiliary mounting body 30 (such as being a metal), and reduce the heat conduction degree when the mounting structure 70 contacts the auxiliary mounting body 30, a plastic part can be added for separation between the mounting structure 70 and the flange 32.

[0100] The radial diameter of the flange 32 is 2 cm - 10 cm larger than the radial diameter of the horn 20. The thickness of the flange 32 is 1 mm - 10 mm, and different regions of the flange 32 may have different thicknesses.

[0101] The sleeve 80 is used to sleeved the refrigerating member 40 and the temperature reducing structure 50 inside the sleeve 80.

[0102] The refrigerating member 40 is electrically connected to the temperature control power supply 90, and the temperature control power supply 90 is used to control the temperature by adjusting the current to change the heat flow of the refrigerating member 40.

[0103] Embodiment 4

[0104] The difference between the ultrasonic oscillator in this embodiment and the ultrasonic oscillator in Embodiment 3 is that a first infusion channel 21 is axially opened in the horn 20. The first infusion channel 21 can extend to the end of the ultrasonic tool head 100 away from the horn 20. A second infusion channel 34 is radially opened in the flange 32, and the second infusion channel 34 is communicated with the first infusion channel 21 to facilitate infusion when using the ultrasonic oscillator. For example, when using the ultrasonic oscillator for eye treatment, the medicine can be input into the eye through the first infusion channel 21 and the second infusion channel 34. The remaining structures are the same as those in Embodiment 3, so they will not be described here again.

[0105] Embodiment 5

[0106] Please refer to Figures 6 - 7 , an ultrasonic oscillator, comprising: a transducer 10, a horn 20, an auxiliary mounting body 30, a refrigerating member 40, a temperature reducing structure 50, a heat conducting layer 60, a mounting structure 70 and a temperature control power supply 90.

[0107] A piezoelectric ring 11 is fixed on the transducer 10.

[0108] One end of the horn 20 is connected to the transducer 10, and the other end of the horn 20 is used to connect to the ultrasonic tool head 100. The other end of the horn 20 is connected to the ultrasonic tool head 100. The ultrasonic tool head 100 is an ultrasonic welding head, an ultrasonic emulsifying head, an ultrasonic cleaning head or an ultrasonic scalpel.

[0109] The auxiliary mounting body 30 includes a flange 32 and a cylinder 33. The cylinder 33 has an installation cavity axially penetrating. The inner ring of the flange 32 is fixed to the nodal region of the horn 20, the outer ring of the flange 32 is fixed to the end of the cylinder 33, or the outer ring of the flange 32 is fixed in the installation cavity of the cylinder 33. Eight second assembly planes 331 are provided on the outer wall of the cylinder 33, so that the outer periphery of the cylinder 33 forms an octagonal prism shape.

[0110] The refrigerating member 40 has opposite cold end 41 and hot end 42, and the cold end 41 is in contact with the second assembly plane 331. For example, three refrigerating members 40 are provided. One refrigerating member 40 is placed on the second assembly plane 331 on the left side, and two stacked refrigerating members 40 are placed on the second assembly plane 331 opposite on the right side.

[0111] Correspondingly, two temperature reduction structures 50 are provided. One temperature reduction structure 50 is fixed to the refrigerating sheet on the left side, and the two refrigerating members 40 on the right side share one temperature reduction structure 50. The temperature reduction structure 50 is adjacent to the hot end 42, and the temperature reduction structure 50 is used to reduce the temperature of the hot end 42. The temperature reduction structure 50 is at least one of a liquid temperature reduction member 50a, a heat dissipation member 50b, and a fan 50c.

[0116] Embodiment 6

[0117] The difference between the ultrasonic vibrator in this embodiment and the ultrasonic vibrator in Embodiment 5 is that a first infusion channel 21 is opened axially in the horn 20, and the first infusion channel 21 can extend to the end of the ultrasonic tool head 100 away from the horn 20. A second infusion channel 34 is opened radially in the flange 32, and the second infusion channel 34 is communicated with the first infusion channel 21 to facilitate infusion when using the ultrasonic vibrator. For example, when using the ultrasonic vibrator for eye treatment, the medicine can be input into the eye through the first infusion channel 21 and the second infusion channel 34. The remaining structures are the same as those in Embodiment 3, so they will not be described here again.
