Description

Technical Field

[0001] The invention relates to the technical field of ultrasonic cleaning, and in particular to a tool head for non-uniform ultrasonic cleaning. Background Art

[0002] Ultrasonic waves have unique properties, so they are widely used in the cleaning field. For ultrasonic cleaning devices, they are generally composed of ultrasonic generators that emit high-frequency oscillations and transmit sound waves through transducers, amplitude transformers, and tool heads.

[0003] Ultrasonic waves have strong beam characteristics and strong directionality. In the cleaning liquid, they will produce a straight-forward flow phenomenon, that is, the cleaning liquid will flow along the vibration direction of the ultrasonic vibrator. The jet generated when the cavitation phenomenon is formed can also remove or weaken the dirt layer, increase the stirring effect, and speed up the cleaning of dirt. Therefore, ultrasonic cleaning is not just the effect of cavitation alone, so enhancing the stirring effect formed by ultrasonic waves can also further improve the cleaning effect.

[0004] In the ultrasonic cleaning device, the tool head is also a very important component. The ultrasonic tool head can affect the ultrasonic sound field, such as changing the ultrasonic radiation area, ultrasonic amplitude, etc., so the tool head will also affect the cleaning effect.

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] Example

[0046] like Figure 1 and Figure 2 As shown, the present invention provides a non-uniform ultrasonic cleaning tool head, comprising: a sleeve 1, a core 2 and a plurality of third sound channels 3, wherein the sleeve 1 is fixed to the horn by a threaded connection, so that the straight sound wave from the horn enters the sleeve 1, and is emitted into the cleaning liquid through the core 2 and the third sound channels 3;

[0047] The core 2 is embedded in the sleeve 1 and fixed to the inner wall of the sleeve 1; the core 2 is provided with two evenly distributed first sound channels 21 and two evenly distributed second sound channels 22, the first sound channels 21 and the second sound channels 22 are arranged alternately, that is, the first sound channels 21 and the second sound channels 22 form a 90-degree angle, and the two first sound channels 21 and the two second sound channels 22 overlap with each other to form four overlapping openings 5 ​​and a tip 4, such as Figure 3 and Figure 4 As shown;

[0048] like Figure 6 and Figure 7 As shown, the first sound channel 21 is composed of a first cone surface 211 and a first cylinder surface 212, and the second sound channel 22 is composed of a second cone surface 221 and a second cylinder surface 222, and the depths and inclination angles of the first cone surface 211 and the second cone surface 221 are different, and the depths of the first cylinder surface 212 and the second cylinder surface 222 are different; the axes of the first cone surface 211, the first cylinder surface 212, the second cone surface 221 and the second cylinder surface 222 are all parallel to the axis of the sleeve 1, and the first cone surface 211 is coaxial with the first cylinder surface 212, and the second cone surface 221 is coaxial with the second cylinder surface 222; however, it should be noted that the depth of the first cone surface 211 and the depth of the second cone surface 221 are both greater than the depth of the overlapped opening 5; ultimately, the structures of the first sound channel 21 and the second sound channel 22 are different in size, forming an uneven sound channel structure.

[0049] Specifically, Fig.10 As shown, the depth of the first channel 21 is the same as the depth of the second channel 22 (h3); Figure 7As shown, the depth of the first conical surface 211 is greater than the depth of the second conical surface 221 (h1>h2), and the inclination angle of the first conical surface 211 is smaller than the inclination angle of the second conical surface 221 (α<β); the depth of the first cylindrical surface 212 is smaller than the depth of the second cylindrical surface 222; the inner diameter of the first cylindrical surface 212 is the same as the minimum inner diameter of the first conical surface 211, and the inner diameter of the second cylindrical surface 222 is the same as the minimum inner diameter of the second conical surface 221; the end of the first cylindrical surface 212 away from the first conical surface 211 and the end of the second cylindrical surface 222 away from the second conical surface 221 are flush;

[0050] Furthermore, the axis of the sleeve 1 passes through the center of the tip 4, the maximum inner diameters of the first cone 211 and the second cone 221 are the same, and the inner diameter of the sleeve 1 is twice the maximum inner diameter of the first cone 211, that is, Figure 3 and Figure 4 As shown, four circles corresponding to the maximum inner diameters of the first conical surface 211 and the second conical surface 221 intersect, and one intersection point is located on the axis of the sleeve 1, and the four circles are inscribed in the sleeve 1;

[0051] Considering the reduction of the loss of the reverse reflection of the sound wave, the outer wall of the core 2 is treated in a certain way, such as Figure 3 and Figure 4 As shown, the projection of the outer peripheral wall of the core body 2 in the axial direction of the sleeve 1 is formed by four intersecting circles corresponding to the maximum inner diameters of the first cone surface 211 and the second cone surface 221, so the third sound channel 3 is also formed, that is, the third sound channel 3 is formed by the outer wall of the core body 2 and the inner wall of the sleeve 1, and the inner walls constituting the third sound channel 3 are perpendicular to the bottom surface of the sleeve 1, so that the sound waves entering in a straight line can be directly emitted;

[0052] From the perspective of the third sound channel 3, the formed overlapped opening 5 and the tip 4, only the sound waves projected on the overlapped opening 5, the tip 4 and the edge of the outer wall of the core 2 will be emitted in the opposite direction. When the four circles corresponding to the maximum inner diameters of the first cone surface 211 and the second cone surface 221 have an intersection point located on the axis of the sleeve 1, and the maximum inner diameters of the first cone surface 211 and the second cone surface 221 are the same and are inscribed in the sleeve 1, the tip 4 at this time is equivalent to a point, and the edges of the overlapped opening 5 and the outer wall of the core 2 at the cone surface are equivalent to a line. Therefore, very few sound waves can be generated in the opposite direction, and it can be considered that most of the sound waves can be emitted through the tool head.

[0053] In addition, due to the existence of the first conical surface 211 and the second conical surface 221, the sound wave will be reflected, and the reflection path is affected by the inclination angle of the conical surface. In order to increase the amount of reflected sound waves, the inclination angle α of the first conical surface 211 is less than 20°, and the inclination angle β of the second conical surface 221 is less than 35°.

[0054] like Fig.10 and Fig.11As shown, we give the reflection situation at the extreme position:

[0055] exist Fig.10 In which α is 18° and β is 34°, when the sound wave J1 is projected at the tip, it is reflected in the first cone surface 211 and then directly projected onto the first cylindrical surface 212. Therefore, in the first sound channel 21, the sound wave J1 will not generate reverse reflection and cause loss; while in the second cone surface 221, the sound wave J1 will generate reverse reflection after being reflected and projected into the horn, so the sound wave cannot be emitted from the tool head, causing loss; similarly, the sound wave J2 will not be reflected in the first sound channel 21, but will be reflected in the second sound channel 22. However, it can be seen that although there is reverse reflection, the amount of reflection will not be large.

[0056] exist Fig.11 In the figure, α is 18° and β is 31°. It can be seen that the sound waves J1 and J2 do not produce reverse reflection. Therefore, reasonable control of the angles of α and β can affect the amount of sound wave reflection. However, it should be noted that when β can satisfy the condition of no reverse reflection, α also satisfies the condition naturally. At the same time, when the angles of α and β are changed, it is necessary to do so when the depths of the first sound channel 21 and the second sound channel 22 remain unchanged, that is, when h3 remains unchanged. Specifically, Fig.13 h2' is less than Fig.12 h2 in the file, while h1 remains unchanged.

[0057] Through the setting of the sound channel, the sound waves passing through the tool head eventually have different directions, that is, the first cone surface 211 and the second cone surface 221 can cause the sound waves to be reflected, so that the sound waves of different angles are emitted from the tool head, and the sound waves not emitted on the cone surface are directly emitted. Figure 5 , Figure 8 and Fig. 9 As shown, Figure 5 The arrows in the figure represent the sound waves emitted from the horn:

[0058] exist Figure 8 In the figure, the sound wave J3 that is not incident on the first cone surface 211 and the second cone surface 221 is directly emitted from the tool head, while the sound waves J1 and J2 that are incident on the second cone surface 221 are reflected by the second cone surface 221, and the final sound waves change their angles and intersect with J3; the same is true for the sound waves incident on the first cone surface 211;

[0059] exist Fig. 9In the embodiment, the sound wave J3 not incident on the first conical surface 211 and the second conical surface 221 is directly emitted from the tool head, while the sound waves J1 and J2 incident on the first conical surface 211 and the second conical surface 221 are reflected by the conical surfaces. The difference in the structures of the first conical surface 211 and the second conical surface 221 makes the sound waves J1 and J2 come out at different inclination angles, thereby producing different effects.

[0060] From the above, it can be seen that the existence of the conical surface changes the formation of the sound waves, causing a part of the sound waves to have an inclination angle, thereby forming multiple sound wave directions and producing stirring in different directions. At the same time, by utilizing the different structural settings of the first sound channel 21 and the second sound channel 22, while forming sound waves in different directions, different losses are generated due to the different reflection paths, thereby forming sound waves of different energies, increasing the unevenness, and further making the flow rate of the cleaning liquid different, which can form a certain laminar flow effect, thereby further improving the cleaning effect.

[0061] like Figure 6 As shown, in order to further change the distribution of the sound field, a boss 6 protruding from the second cylindrical surface 222 is provided at the end of the second cylindrical surface 222 away from the second conical surface 221, and the two bosses 6 on the two second cylindrical surfaces 222 are also evenly distributed along the circumference of the sleeve 1, and the boss 6 has an inner wall with the same inner diameter as the second cylindrical surface 222, and an outer wall with the same maximum inner diameter as the second conical surface 221, and the inner wall and the outer wall of the boss 6 are coaxial with the second cylindrical surface 222; at the same time, the boss 6 protrudes from the sleeve 1, and the end of the first cylindrical surface 212 away from the first conical surface 211, the end of the second cylindrical surface 222 away from the second conical surface 221, and the end of the sleeve 1 away from the first conical surface 211 are all flush;

[0062] That is, the arrangement of the boss 6, on the one hand, extends the length of the second sound channel 22, so that the reflection path of a part of the sound waves is increased and the emission position is changed, further increasing the unevenness of the sound field. On the other hand, the arrangement of the boss 6 changes the sound field of the second sound channel 22, so that there is basically no sound wave emitted on the side of the boss 6 away from the axis of the sleeve 1, which further promotes the formation of an uneven sound field. Fig.12 As shown:

[0063] For the first sound channel 21, since there is no boss 6 in the first sound channel 21, the sound waves coming out of the first sound channel 21 exist in the circumferential direction, as shown by the dotted arrow and the solid arrow at the first sound channel 21 in the figure;

[0064] For the second sound channel 22, due to the presence of the boss 6, no sound waves are emitted from the back side of the boss 6. Fig.11It can be seen that the sound waves that are not incident on the boss 6 will directly exit the tool head, while the sound waves that are incident on the boss 6 will be reflected again and incident on the axis of the sleeve 1. If the boss 6 does not exist, the sound waves will be incident on the back side of the boss 6, thus eventually forming a fan-shaped sound wave field at the second sound channel 22 (as indicated by the solid arrow at the first sound channel 21);

[0065] Finally formed Fig.12 The sound wave field is formed at the center of the core 2, that is, reflected sound waves from the two first sound channels 21 and the two second sound channels 22 are formed, where the degree of convection is the largest; there are sound waves on the far side of the first sound channel 21, and there are no sound waves on the far side of the second sound channel 22, so that a weaker sound field is formed around the core 2; finally, the overall sound field is unevenly distributed, and at the same time, when the structures of the first sound channel 21 and the second sound channel 22 are different, the sound waves are reflected differently and the losses are different, and then the energy generated is different, which promotes the formation of an uneven sound field and produces different stirring effects;

[0066] Furthermore, the central angle of the inner wall of the boss 6 is an obtuse angle, and the projections of the ends of the maximum inner diameter of one of the second cylindrical surfaces 222 and the two first conical surfaces 211 in the axial direction of the sleeve 1 form three intersecting circles, and the central angle O formed by the intersection of the two distal ends of the three intersecting circles and the center of the projection of the second cylindrical surface 222 is the same as the central angle of the inner wall of the boss 6; that is, Fig.13 As shown, the central angle corresponding to the inner wall of the boss 6 is shown as O in the figure.

[0067] When in use, the tool head is mounted on the horn and placed near the object to be cleaned. In actual operation, multiple tool heads can be arranged near the object to be cleaned, or the tool head can be moved. After the ultrasonic wave passes through the tool head, there is a direct sound wave with the largest energy, and a reflected sound wave with weaker energy than the direct sound wave and emitted at an angle. In addition, the energy of the reflected sound waves passing through the first sound channel 21 and the second sound channel 22 is also different, so that sound waves of different energies are formed as a whole. When the sound waves are injected into the cleaning liquid, different straight-in flows are formed, which causes the liquid to form different flow rates, thereby producing cross-flow and laminar flow effects, thereby improving the degree of turbulence and stirring effect of the cleaning liquid. In addition, the difference in the structure of the first sound channel 21 and the second sound channel 22 itself further changes the distribution range of the sound waves and improves the unevenness of the sound field.

[0068] In addition, when the tool head is used, it is necessary to ensure that the direction of the sound waves coming out of the amplitude transformer is along the axial direction of the sleeve 1, and the range of the sound waves is kept within the sleeve 1 as much as possible to reduce losses. At the same time, the inner walls of the first sound channel 21 and the second sound channel 22 must have better smoothness to improve reflection.

[0069] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
