Description

Technical Field

[0001] The invention relates to the technical field of ultrasonic cleaning, and in particular to a non-uniformly distributed ultrasonic cleaning device. 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 oscillation signals, and sound waves are emitted through transducers, amplitude transformers, and tool heads.

[0003] The cleaning liquid of the existing ultrasonic cleaning device is generally static and does not flow. As the number of cleaning times increases, more and more dirt will be present. At the same time, static liquid has basically no flushing effect on the object. Therefore, while considering the effect of ultrasound alone, increasing the agitation of the cleaning liquid will make the cleaning effect better.

[0004] The cleaning device of the present invention is inspired by the "non-uniform distribution" in the non-uniformly distributed ultrasonic tool head. It utilizes the similarities between sound waves and fluid flow and improves the flow channel structure of the cleaning liquid. On the one hand, it realizes the flushing effect of the cleaning liquid. On the other hand, it combines the reflection of ultrasonic waves to ensure that the ultrasonic waves can fully produce the ultrasonic cleaning effect in the flowing liquid, thereby producing a dual effect, thereby improving the cleaning effect. Summary of the invention

[0009] The first flow channel is composed of a first conical surface and a first cylindrical surface, and the second flow channel is composed of a second conical surface and a second cylindrical surface, and the first conical surface and the second conical surface have different depths and inclination angles, and the first cylindrical surface and the second cylindrical surface have different depths and inner diameters; the axes of the first conical surface, the first cylindrical surface, the second conical surface and the second cylindrical surface are all parallel to the axis of the cleaning body, and the center distance between the two first conical surfaces is different from the center distance between the two second conical surfaces;

[0010] The sealing ring is provided with four ultrasonic transmitters evenly distributed along the circumference. The ultrasonic waves emitted by the ultrasonic transmitters extend into the first flow channel and the second flow channel, and the emission direction of the ultrasonic waves is perpendicular to the axis of the cleaning body.

[0011] Preferably, the depth of the first flow channel is the same as the depth of the second flow channel;

[0014] The center distance between the two first conical surfaces is smaller than the center distance between the two second conical surfaces;

[0015] The axis of the first cylindrical surface on one of the cleaning bodies, the axis of the second cylindrical surface on the other cleaning body, and the axis of the cleaning body are coplanar.

[0016] Preferably, the inclination angle of the first conical surface and the inclination angle of the second conical surface are both acute angles, and are both less than 45°.

[0052] 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.

[0053] Example

[0054] like Figure 1 As shown, the present invention provides a non-uniform ultrasonic cleaning device, including a bracket 01, on which a cleaning unit is arranged; Figure 2 and Figure 3 The cleaning unit comprises two cylindrical cleaning bodies 1 which are matched together, the two cleaning bodies 1 are sealed and connected by a sealing ring 3, and one of the cleaning bodies 1 can produce axial displacement relative to the other cleaning body 1; a circular tube 2 is arranged on each of the two cleaning bodies 1, and the two circular tubes 2 are respectively connected to an external filtering device;

[0055] That is, the entire cleaning unit is placed on the bracket 01, and the sealing ring 3 realizes the sealing of the two cleaning bodies 1. In this embodiment, the sealing of the two is realized by the sealing ring 31. Fig. 9 As shown, one of the cleaning bodies 1 is sealed and fixed with the sealing ring 3, and the other is inserted in the sealing ring 3. A number of O-rings are fixed on the outer wall of the cleaning body 1 inserted in the sealing ring 3, and a number of sealing ring grooves are correspondingly opened in the sealing ring 3 for the O-rings to press tightly. Further, in order to facilitate the displacement of the cleaning body 1, the inner wall of the sealing ring 3 needs to be as smooth as possible; in addition, in order to facilitate the axial displacement of one of the cleaning bodies 1, a number of guide pillars 02 are arranged on the bracket 01. Figure 1 A slip ring 03 is fixed on the outer wall of the cleaning body 1 in the middle upper part, and the slip ring 03 is nested on the guide column 02 to achieve axial guidance. In addition, a limit ring 05 can be fixed on the guide column 02 to limit the cleaning body 1 from moving further downward;

[0056] Furthermore, considering that one of the cleaning bodies 1 can move axially, a section of bellows 04 is arranged on the circular tube 2 of the cleaning body 1, thereby providing space for the displacement of the cleaning body 1; for the filtering device, the filtering device can adopt the filtering equipment in the prior art, and the specific embodiment will not be described in detail. For example, the liquid filter in the prior art, it should be noted that the filtering device also needs to be additionally connected to a water pump to provide flow power for the cleaning liquid, so that the cleaning liquid forms a circulating flow.

[0057] Combination Figure 4 and Figure 5 The cleaning body 1 is provided with two evenly distributed first flow channels 11 and two evenly distributed second flow channels 12, the first flow channels 11 and the second flow channels 12 are arranged alternately, that is, the first flow channel 11 and the second flow channel 12 form an angle of 90 degrees, wherein the first flow channel 11 is composed of a first conical surface 111 and a first cylindrical surface 112, and the second flow channel 12 is composed of a second conical surface 121 and a second cylindrical surface 122, the two first flow channels 11 and the two second flow channels 12 overlap with each other to form four overlapping openings 14 and a platform 13, that is, the two first conical surfaces 111 and the two second conical surfaces 121 overlap with each other to form four overlapping openings 14 and a platform 13, which also means that the circles at the maximum outer diameters of the two first conical surfaces 111 do not intersect, and the circles at the maximum outer diameters of the two second conical surfaces 121 do not intersect;

[0058] In order to change the flow direction of the liquid, based on 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 need to overlap at least partially, that is, Figure 8As shown in the perspective view, the bold part is the flow channel of one of the cleaning bodies 1, and the unbold part is the flow channel of the other cleaning body 1, and the two overlap; at the same time, the depth and inclination angle of the first conical surface 111 and the second conical surface 112 are different, and 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 second cylindrical surface 122 are all parallel to the axis of the cleaning body 1, and at the same time, 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 between the two first conical surfaces 111 is different from the center distance between the two second conical surfaces 112; 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 overlapped opening 14;

[0059] Specifically, Figure 6 As shown, 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 inclination angle (α) of the first conical 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 (i.e., R1=R2); the depth of the first cylindrical surface 112 is smaller than the depth of the second cylindrical surface 122, and 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 is the same as the minimum inner diameter of the first conical surface 111, and the inner diameter (r2) of the second cylindrical surface 122 is the same as the minimum inner diameter of the second conical surface 121; the center distance between the two first conical surfaces 111 is smaller than the center distance between the two second conical surfaces 121, i.e. Figure 3 One surface of the platform 13 is thin in the middle and thick at both ends (thickened part); in addition, the axis of the first cylindrical surface 112 on one cleaning body 1, the axis of the second cylindrical surface 122 on the other cleaning body 1, and the axis of the cleaning body 1 are coplanar, that is, Figure 8 As shown in FIG. 1 , one of the cleaning bodies 1 is rotated 90 degrees relative to the other cleaning body 1 , so that after overlapping, the three cleaning bodies 1 are coplanar.

[0060] Furthermore, the axis of the cleaning body 1 passes through the center of the platform 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 are both less than 45°;

[0061] Furthermore, due to the presence of two first flow channels 11 and two second flow channels 22, four ultrasonic transmitters 4 are evenly distributed in the circumferential direction around the sealing ring 3. The ultrasonic transmitter 4 is an existing device, for example, it can be a tool head for transmitting ultrasonic waves, which is connected to a horn, a transducer, an ultrasonic generator, etc., so as to improve the ultrasonic wave for this application and make the emission direction of the ultrasonic wave perpendicular to the axial direction of the cleaning body 1;

[0062] In order to provide a sound channel 15 for ultrasound, such as Figure 4 As shown, four evenly distributed sound channels 15 are provided on the surfaces of the two cleaning bodies 1 that are close to each other, and the sound channels 15 penetrate to the corresponding first conical surface 111 and second conical surface 121. When the two cleaning bodies 1 are matched together, each sound channel 15 is combined into four cylindrical holes, and four mounting holes are provided on the sealing ring 3, and the four mounting holes are respectively coaxial with the four cylindrical holes formed by the sound channels 15, and the ultrasonic transmitter 4 is sealed in the four mounting holes of the sealing ring 3, and finally the ultrasonic emission is realized;

[0063] from Figure 4 It can be seen from Zhonghe 9 that a structure similar to a spherical cavity is formed by the conical surfaces being matched. When ultrasonic waves are injected, the sound waves will be reflected back and forth many times in the two conical surfaces matched together, forming an echo effect, so that the ultrasonic waves can fill the flow channel, thereby ensuring that the ultrasonic waves can fully produce ultrasonic cleaning effects in the flowing liquid.

[0064] Further, according to this embodiment, we simulated the liquid flow direction of this embodiment and made two comparative examples, wherein the simulation software was FloXpress (first level qualitative flow analysis tool) in Solidworks;

[0065] It is particularly noted that since the simulation requires the inlet and outlet to be blocked, a part is provided at both round tubes 2 for sealing during the actual simulation; in addition, since the drawings do not allow for the presence of colors, Figure 10-Figure 19 Grayscale is used for display, that is, it is displayed by depth. According to 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, after being grayscaled, the blue and red colors both become dark colors. However, according to actual conditions, the high speed is concentrated in the flow channel, and the dark color in the circular tube 2 represents a tendency towards blue.

[0066] This embodiment and the comparative example are carried out using the same parameters, and the misalignment 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:

[0076] For this example:

[0077] like Fig.10 As shown, it can be seen that the flow direction of the liquid changes, the liquid in the second flow channel 12 forms a split flow, a part of the liquid flows into the first flow channel 11 and forms a vortex (rotating liquid flow) in the first flow channel 11 and the second flow channel 12, and the liquid flowing in series merges with the liquid in the first flow channel 11 at the same time, further increasing the turbulence of the liquid and improving the stirring and flushing effect; Fig.11 For a bird's-eye view, Fig.12 For Fig.10 The schematic diagram of the parts after blurring is based on the model, so that the boundaries of the flow channels and the direction of liquid flow can be more easily seen.

[0078] Comparative Example 1:

[0079] like Fig.13 and Fig.14 As shown, 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 maximum inner diameters of the first conical surfaces 111 of the first flow channel 11 and the second flow channel 12 are the same, and the center distance between the two opposite first conical surfaces 111 is the same as the center distance between the two opposite second conical surfaces 121, that is, the four sides of the formed platform 13 are evenly distributed in the circumferential direction; the difference between the first flow channel 11 and the second flow channel 12 is that the inner diameter and depth of the first cylindrical surface 112 and the second cylindrical surface 122 are different, the inclination angle of the first conical surface 111 is different from that of the second conical surface 121, and the depth is also different;

[0080] The difference between the comparative example 1 and the present embodiment is that: "the center distance between the two opposite first conical surfaces 111 is the same as the center distance between the two opposite second conical surfaces 121", and the comparative example 1 further improves the uniform distribution of the flow channels;

[0081] like Fig.14 and Fig.15 As shown, it can be seen that although the flow direction of the liquid has changed to a certain extent, what is produced is that the liquid is divided by the overlapped opening 14, and the "series flow" of this embodiment is not produced, and further, no rotating liquid flow is formed;

[0082] in, Fig.13 For Fig.15 A perspective view of the flow channel based on the foundation; Fig.14 For Fig.15 The schematic diagram of the parts after blurring is based on the model, so that the boundaries of the flow channels and the direction of liquid flow can be more easily seen.

[0083] Comparative Example 2:

[0084] like Fig.16 and Fig.17 As shown, the flow channel structure of the cleaning body 1 is changed at this time, and the two first flow channels 11 and the two second flow channels 12 are completely the same in size and structure and are evenly distributed in the circumferential direction;

[0085] The difference between Comparative Example 2 and this embodiment is that "a uniformly distributed structure is adopted", that is, the flow channels of Comparative Example 2 are uniformly distributed in the circumferential direction;

[0086] like Fig.17 and Fig.18 As shown, it can be seen that although the flow direction of the liquid has changed to a certain extent, the liquid is only divided by the overlapped opening 15, and the "series flow" of this embodiment is not generated, and no rotating liquid flow is formed, which is similar to Comparative Example 1;

[0087] in, Fig.16 For Fig.18 A perspective view of the flow channel based on the foundation; Fig.17 For Fig.18 The schematic diagram of the parts after blurring is based on the model, so that the boundaries of the flow channels and the direction of liquid flow can be more easily seen.

[0088] Comparative Example 3:

[0089] like Fig.19 As shown, this comparative example is a simulation diagram after the four flow channels of the two cleaning bodies 1 are coaxial in pairs based on comparison 2. It can be seen that after coaxiality, it is equivalent to the existence of a straight channel, so it can be seen that even the effect of diversion is reduced, and there is no rotating airflow formed by "series flow".

[0090] From the above, it can be seen that the present embodiment forms a non-uniform flow channel setting through the difference in structure between the first flow channel 11 and the second flow channel 12, thereby being able to divert the liquid. A portion of the liquid flows into the first flow channel 11 and forms vortices in the first flow channel 11 and the second flow channel 12. The liquid flowing in series simultaneously merges with the liquid in the first flow channel 11, further increasing the degree of turbulence of the liquid and improving the stirring and flushing effect.

[0091] When in use, the cleaning device is connected to the external filtering device through the round tube 2 and the bellows 04, and the water pump provides power for the circulation of the cleaning liquid; when cleaning is needed, the cleaning device is moved Figure 1The cleaning body 1 at the upper middle part separates the two matched cleaning bodies 1, and then the object to be cleaned is placed in the conical surface, and then the upper cleaning body 1 is lowered to be inserted into the sealing ring 3, and then the cleaning liquid is introduced and ultrasonic waves are emitted, and cleaning is achieved through the dual effects of ultrasonic waves and cleaning liquid. In this process, the cleaning liquid forms a rotating liquid flow to increase the flushing effect, and the ultrasonic wave also uses the matched conical surface to fully produce the ultrasonic cleaning effect in the flowing liquid, and finally improves the overall cleaning effect; during the circulation of the cleaning liquid, the external filtering device can filter impurities to reduce secondary pollution to the object to be cleaned;

[0092] In addition, it should be noted that since the main cleaning position of the cleaning device is within the first conical surface 111 and the second conical surface 121, the space that can be cleaned by the cleaning device is relatively small as a whole. Therefore, the cleaning device is more suitable for cleaning small objects, that is, during the cleaning process, too large objects cannot be placed in the cleaning space to occupy most of the cleaning space, which greatly affects the liquid circulation. At the same time, considering the cleaning of smaller objects, it can be Figure 1 A cross bracket is provided at the position close to the conical surface of the first cylindrical surface 112 and the second cylindrical surface 122 of the cleaning body 1 below to activate the auxiliary support function. It should be noted that the cross bracket is as thin as possible to reduce the impact on the liquid flow.

[0093] 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.
