In order to realize the change of the liquid flow direction, on the basis of the above structure, the first flow channel 11 of one cleaning body 1 and the second flow channel 12 of the other cleaning body 1 should at least partially overlap, that is, as shown in the perspective view of FIG. 8 . As shown in the figure, the flow channel of one cleaning body 1 is bolded, and the flow channel of the other cleaning body 1 is not bolded, and the two overlap; The angles are different, the depth and inner diameter of the first cylindrical surface 112 and the second cylindrical surface 122 are different; the axes of the first conical surface 111, the first cylindrical surface 112, the second conical surface 121 and the The axes of the body 1 are parallel to each other, the first conical surface 111 is coaxial with the first cylindrical surface 112, the second conical surface 121 is coaxial with the second cylindrical surface 122, and the center distance of the two first conical surfaces 111 is the same as that of the two The center distance of the second conical surface 112 is different; however, it should be noted that the depth of the first conical surface 111 and the depth of the second conical surface 121 are both greater than the depth of the coincident opening 14;

Specifically, as shown in FIG. 6 , the depth of the first flow channel 11 is the same as the depth of the second flow channel 11 ; the depth (h1) of the first conical surface 111 is greater than the depth (h2) of the second conical surface 112, and the first The inclination angle (α) of the surface 111 is smaller than the inclination angle (β) of the second conical surface 112 ; the maximum inner diameters of the first conical surface 111 and the second conical surface 112 are the same (ie R1=R2 ); the depth of the first cylindrical surface 112 less than the depth of the second cylindrical surface 122, the inner diameter (r1) of the first cylindrical surface 112 is smaller than the inner diameter (r2) of the second cylindrical surface 122; the inner diameter (r1) of the first cylindrical surface 112 and the minimum inner diameter of the first tapered surface 111 In the same way, the inner diameter (r2) of the second cylindrical surface 122 is the same as the minimum inner diameter of the second conical surface 121; One surface of the table body 13 has a structure with a thin middle and thick ends (bold parts); in addition, the axis of the first cylindrical surface 112 on one of the cleaning bodies 1 and the axis of the second cylindrical surface 122 on the other cleaning body 1 . The axes of the cleaning bodies 1 are coplanar, that is, as shown in FIG. 8 , one of the cleaning bodies 1 is rotated 90 degrees relative to the other cleaning body 1 , so after overlapping, the above three are coplanar.

Further, the axis of the cleaning body 1 passes through the center of the table body 13, and the inclination angle of the first conical surface 111 and the inclination angle of the second conical surface 121 are both acute angles, and both are less than 45°;

Further, since there are two first flow channels 11 and two second flow channels 22, four ultrasonic transmitting heads 4 are arranged around the sealing ring 3 evenly distributed in the circumferential direction, and the ultrasonic transmitting heads 4 are existing devices. , for example, it can be a tool head that emits ultrasonic waves, and it is connected with a horn, a transducer, an ultrasonic generator, etc., so as to improve the ultrasonic wave for the application, and make the emission direction of the ultrasonic wave perpendicular to the axial direction of the cleaning body 1;

In order to provide channels 15 for ultrasonic waves, as shown in FIG. 4 , four evenly distributed channels 15 are opened on the surfaces of the two cleaning bodies 1 that are close to each other, and the channels 15 penetrate to the corresponding first cone surface 111 and the first The two-cone surface 121, when the two cleaning bodies 1 are combined together, each channel 15 is combined into four cylindrical holes, and the sealing ring 3 is provided with four mounting holes, and the four mounting holes are respectively connected with the channel The four cylindrical holes formed by 15 are coaxial lines, and the ultrasonic transmitting head 4 is sealed in the four mounting holes of the sealing ring 3 to finally realize the transmission of ultrasonic waves;

It can be seen from Figures 4 and 9 that a structure similar to a spherical cavity is formed by the way of conical surfaces. Reflected to form an echo effect, so that the ultrasonic wave can be flooded in the flow channel, thereby ensuring that the ultrasonic wave can fully produce the effect of ultrasonic cleaning in the flowing liquid.

Further, according to this embodiment, we simulate the liquid flow direction in this embodiment and make two comparative examples, wherein the simulation software is FloXpress (the first qualitative flow analysis tool) in Solidworks;

In particular, since the simulation needs to block the inlet and outlet, in the actual simulation process, a part is set at the two circular tubes 2 for sealing; 10-Fig. 19 all use grayscale display, that is, display by shades. According to the actual simulation, the lower the speed, the bluer the color, and the higher the speed, the redder the color. Therefore, in the speed legend in the figure, the color is grayed out. After 10 degrees, both blue and red become dark, but according to the actual situation, the high speed is concentrated in the flow channel, and the dark color in the circular tube 2 means that it is biased towards blue.

The present embodiment and the comparative example are carried out with the same parameters, and at the same time, the dislocation angles of the two cleaning bodies 1 are the same, that is, one of them is rotated 90 degrees relative to the other, as follows:

For this example:

As shown in FIG. 10 , it can be seen that the flow direction of the liquid changes, the liquid in the second flow channel 12 forms a split flow, and a part of the liquid flows into the first flow channel 11 and flows in the first flow channel 11 and the second flow channel 12 . A vortex (rotating liquid flow) is formed, and the liquid flowing in the series merges with the liquid in the first flow channel 11 at the same time, which further increases the degree of turbulence of the liquid and improves the effect of stirring and washing; FIG. 11 is a top view, and FIG. 12 is a Based on Figure 10, the schematic diagram of the parts is blurred, so that it is easier to see the boundary of the flow channel and the flow direction of the liquid.

Comparative Example 1:

As shown in FIG. 13 and FIG. 14 , the flow channel structure of the cleaning body 1 is changed at this time. At this time, the two first flow channels 11 and the two second flow channels 12 are evenly distributed in the circumferential direction, and the first flow channels 11 It is the same as the maximum inner diameter of the first conical surface 111 of the second flow channel 12, and the center distance of the two opposite first conical surfaces 111 is the same as the center distance of the two opposite second conical surfaces 121, that is, the truncated body is formed. The four sides of 13 are evenly distributed in the circumferential direction; the difference between the first flow channel 11 and the second flow channel 12 is: the inner diameter and depth of the first cylindrical surface 112 and the second cylindrical surface 122 are different, and the inclination angle of the first conical surface 111 is different. Different from the second conical surface 121 and also different in depth;

The difference between the comparative example 1 and this embodiment is: "the center distance of the two opposite first conical surfaces 111 is the same as the center distance of the two opposite second conical surfaces 121", the comparative example 1 further improves the flow channel uniform distribution;

As shown in Figures 14 and 15, it can be seen that although the flow direction of the liquid has changed to a certain extent, the only result is that the liquid is divided by the coincidence port 14, but the "serial flow" of this embodiment is not produced, and furthermore, no rotating liquid is formed. flow;

13 is a perspective view of the flow channel on the basis of FIG. 15 ; FIG. 14 is a schematic diagram after the parts are virtualized on the basis of FIG. 15 , so as to more easily see the boundary of the flow channel and the flow direction of the liquid.

Comparative Example 2:

As shown in FIG. 16 and FIG. 17 , the flow channel structure of the cleaning body 1 is changed at this time, and the size and structure of the two first flow channels 11 and the two second flow channels 12 at this time are exactly the same and evenly distributed in the circumferential direction;

In contrast 2, the change in this embodiment is: "a uniformly distributed structure is adopted", that is, the flow channels of comparative example 2 are evenly distributed in the circumferential direction;

As shown in Fig. 17 and Fig. 18 , it can be seen that although the flow direction of the liquid has changed to some extent, the only result is that the liquid is divided by the coincidence port 15, and the "serial flow" of this embodiment is not generated, and furthermore, no rotating liquid is formed. flow, which is similar to that of Comparative Example 1;

16 is a perspective view of the flow channel on the basis of FIG. 18 ; FIG. 17 is a schematic diagram after the parts are virtualized on the basis of FIG. 18 , so that the boundary of the flow channel and the flow direction of the liquid can be more easily seen.

Comparative Example 3:

As shown in Figure 19, this comparative example is a simulation diagram after the four flow channels of the two cleaning bodies 1 are coaxial two by two on the basis of the comparison 2. It can be seen that there is a straight channel after being coaxial. , so it can be seen that even the effect of shunt flow is reduced, and there is no swirling airflow formed by "serial flow".

From the above, it can be seen that in this embodiment, a non-uniform flow channel arrangement is formed due to the difference in the structure of the first flow channel 11 and the second flow channel 12 , which can further divide the liquid, and a part of the liquid flows into the first flow channel 11 A vortex is formed in the first flow channel 11 and the second flow channel 12, and the liquid flowing in the series merges with the liquid in the first flow channel 11 at the same time, which further increases the degree of turbulence of the liquid and improves the effect of stirring and flushing.

When in use, the cleaning device is connected to the external filter device through the circular pipe 2 and the bellows 04, and provides the power to circulate the cleaning liquid through the water pump; The two opposite cleaning bodies 1 are separated, and then the object to be cleaned is placed in the cone surface, and then the cleaning body 1 above is put down to be inserted into the sealing ring 3, and then the cleaning liquid is introduced and ultrasonic waves are emitted. The dual action of the liquid achieves cleaning. During this process, the cleaning liquid forms a rotating liquid flow to increase the washing effect, and the ultrasonic wave also uses the opposing cone surface to fully produce the effect of ultrasonic cleaning in the flowing liquid, which ultimately improves the overall cleaning effect. In the process of liquid circulation, the external filter device can filter the impurities and reduce the secondary pollution to the objects to be cleaned;

In addition, it should be noted that since the main cleaning positions of the cleaning device are in the first conical surface 111 and the second conical surface 121, the overall cleaning space of the cleaning device is relatively small, so the cleaning device is more suitable for The cleaning of small objects, that is, in the process of cleaning, can not put too large objects and occupy most of the cleaning space, which will greatly affect the liquid flow circulation; at the same time, considering the cleaning of small objects, it can be A cross bracket is set at the position of the first cylindrical surface 112 and the second cylindrical surface 122 of the cleaning body 1 below Fig. 1 near the tapered surface to activate the auxiliary support function. It should be noted that the cross bracket should be as thin as possible to reduce the impact on the effect of liquid flow.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention. Thus, provided that 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.
