The body includes a shell 1 and a flip cover 2 rotatably connected to the shell 1. A rotating joint 3 is provided between the flip cover 2 and the shell 1. The flip cover 2 covers the upper part of the shell 1. The flip cover 2 can be flipped relative to the shell 1 by force through the rotating joint 3 to open the ultrasonic cleaning device, making it convenient for the user to put in the items to be cleaned. The shell 1 has a first receiving cavity 10, and the flip cover 2 has a second receiving cavity 21. The rotating joint 3 is provided with... The device has a first wiring channel 31 communicating with the first receiving cavity 10 and the second receiving cavity 21. The body contains a lead wire structure located on one side of the rotating joint 3. The lead wire structure includes a second wiring channel 4 communicating with the first wiring channel 31. In this embodiment, the first receiving cavity 10 is used to install the main control module and the ultrasonic cleaning module. The ultrasonic cleaning module includes at least a cleaning inner tank 5 and an ultrasonic transducer. The cleaning inner tank 5 is located inside the first receiving cavity 10, and the main control module is located below the cleaning inner tank 5. The ultrasonic transducer can be directly connected to the cleaning inner tank 5. The connection can be direct or indirect, and this embodiment does not specify a particular connection. The second receiving cavity 21 is used to install the operation panel module. The first receiving cavity 10 is provided with a first circuit board S1, and the second receiving cavity 21 is provided with a second circuit board S2. The first circuit board S1 and the second circuit board S2 are connected by a wire S3. During assembly, the wire S3 passes through the first wiring channel 31 and the second wiring channel 4 and connects between the first circuit board S1 and the second circuit board S2. In this embodiment, by setting the first wiring channel 31 at the rotating joint 3, the wiring layout of the ultrasonic cleaning device is optimized, the compactness and simplicity of the internal structure of the ultrasonic cleaning device are increased, and the wire S3 can be housed in the second receiving cavity 21, while ensuring the normal flip-opening and closing of the flip cover 2. In addition, by setting an additional lead wire structure to further fix the wire S3, and by using the second wiring channel 4 in conjunction with the first wiring channel 31 to install the wire S3, the reliability and safety of the wiring layout inside the ultrasonic cleaning device can be increased, the protection of the wire S3 can be enhanced, and the safety risks of the ultrasonic cleaning device can be reduced.

[0035] Specifically, the lead wire structure is disposed inside the outer shell 1 and / or the flip cover 2. The lead wire structure is disposed opposite to the rotating joint 3, which helps to reduce the total length of the first wiring channel 31 and the second wiring channel 4, reduce the length of the wire S3, thereby reducing the production cost of the ultrasonic cleaning device, optimizing the electrical performance of the ultrasonic cleaning device, and increasing the internal space utilization of the ultrasonic cleaning device.

[0036] like Figure 3 and Figure 7As shown, one embodiment of the lead wire structure is as follows: the outer shell 1 includes an upper shell 11 rotatably connected to the flip cover 2, a base 12 disposed at the lower part of the upper shell 11, and a connector 13 disposed between the upper shell 11 and the base 12. The upper shell 11, connector 13, and base 12 are connected longitudinally in sequence, forming an upwardly open first receiving cavity 10 by the upper shell 11, connector 13, and base 12. The rotating joint 3 is disposed at the top of the upper shell 11 and connected to the flip cover 2. A first extension portion 14 extending toward the first receiving cavity 10 is provided on one side of the connector 13. The second wiring channel 4 includes a first wire hole 41 disposed in the first extension portion 14 and communicating with the first receiving cavity 10. A first limiting part 411 is provided on the outer side, that is, the first wire hole 41 is longitudinally inserted into the first extension 14, and the first limiting part 411 is formed in the first extension 14. The first wire hole 41 is opposite to the inlet of the first wiring channel 31. In this embodiment, the first circuit board S1 is installed in the base 12, and one end of the wire S3 is connected to the top of the first circuit board S1 to form a first connection endpoint. The inlet of the first wiring channel 31 is located above the first connection endpoint, which is beneficial to shorten the internal wiring length of the ultrasonic cleaning device and improve the internal space utilization of the ultrasonic cleaning device. The first wire hole 41 is located between the inlet of the first wiring channel 31 and the first connection endpoint and is offset outward, that is, as Figure 5 As shown, the first wire hole 41 is located to the upper right of the first connection end. The wire S3 passes through the first wire hole 41 and is fixed in the first wire hole 41 by the first limiting part 411 and away from the ultrasonic cleaning module, so as to avoid the wire S3 from contacting the ultrasonic cleaning module and being easily damaged, and further improve the reliability of the electrical connection of the ultrasonic cleaning device.

[0037] To improve the connection stability between the upper shell 11, the connector 13, and the base 12, in some alternative embodiments, such as Figure 3 , 7As shown in Figure 8, the connector 13 includes a first snap-fit ​​portion 131, a second snap-fit ​​portion 132, and a clamping portion 133 connected in sequence. The second snap-fit ​​portion 132 is laterally disposed between the first snap-fit ​​portion 131 and the clamping portion 133. The first extension portion 14 is disposed on the side of the clamping portion 133 facing the first receiving cavity 10. The two ends of the clamping portion 133 extend longitudinally and form an upwardly open first clamping groove and a downwardly open second clamping groove between the first snap-fit ​​portion 131 and the clamping portion 133, respectively. The second snap-fit ​​portion 132 is located between the first clamping groove and the second clamping groove. The bottom of the upper shell 11 is provided with a first mating portion 114 adapted to the first clamping groove. The top of the base 12 is provided with a second mating portion 121 adapted to the second clamping groove. A mating portion adapted to the first snap-fit ​​portion 131 is formed between the upper shell 11 and the base 12. The third clamping groove; during assembly, the first snap-fit ​​part 131 is engaged in the third clamping groove, the first mating part 114 is engaged in the first clamping groove, and the second mating part 121 is engaged in the second clamping groove. The second snap-fit ​​part 132 is clamped by the first mating part 114 and the second mating part 121, and the upper shell 11 and the base 12 are clamped by the first snap-fit ​​part 131 and the clamping part 133. This helps to improve the connection stability between the upper shell 11, the connector 13 and the base 12. Moreover, the connection between the upper shell 11, the connector 13 and the base 12 is simple and easy to manufacture and assemble. In addition, the first wire hole 41 extends toward the first snap-fit ​​part 131 and communicates with the first clamping groove and the second clamping groove to increase the space of the first wire hole 41 so that the first wire hole 41 can accommodate wires S3 of different thicknesses. Optionally, the bottom of the first mating part 114 is further provided with a third mating part 115 extending toward the base 12. The base 12 is provided with a groove 1211 adapted to the third mating part 115. The first extension part 14 is provided with at least two first wire holes 41. The first wire hole 41 corresponding to the lower part of the rotating joint 3 is used for wire routing. The other first wire hole 41 is correspondingly provided with the third mating part 115 so that the third mating part 115 can pass through. This further improves the connection stability between the upper shell 11, the connector 13 and the base 12. Moreover, by providing several first wire holes 41 with the same structure in the connector 13, the production difficulty of the connector 13 can be reduced and the production efficiency of the connector 13 can be improved.

[0038] like Figure 5 and Figure 10As shown, in a second embodiment of the lead wire structure, the flip cover 2 includes an upper cover 22, an upper cover pivot plate 23, and an upper cover seat 24. The upper cover pivot plate 23 covers the top of the upper cover seat 24, and the upper cover 22 is located outside the upper cover pivot plate 23. The second receiving cavity 21 is located inside the upper cover seat 24, and the upper cover seat 24 also has a mounting cylinder 241. The second wiring channel 4 further includes a second wire-passing hole 42 located in the mounting cylinder 241 and communicating with the second receiving cavity 21. The second wire-passing hole 42 is opposite to the outlet of the first wiring channel 31. In this embodiment, the mounting cylinder 241 extends from the bottom of the second receiving cavity 21 toward the top of the second receiving cavity 21, and the wire-passing hole 42 is located in the mounting cylinder 241. The second receiving cavity 21 is divided into a first cavity 211 and a second cavity 212. The operation panel module is installed through the first cavity 211, which appropriately reduces the installation space of the operation panel module, enhances the sealing of the installation space, effectively prevents water from entering the operation panel module, and helps to reduce the volume of the upper cover 24, thereby reducing production costs. During electrical assembly, the wire S3 passes through the first wiring channel 31 and the second wiring hole 42 and is connected to the second circuit board S2. By setting the second wiring hole 42 opposite to the outlet of the first wiring channel 31, the connection length between the wire S3 and the second circuit board S2 is further shortened, thereby further reducing the production cost of the ultrasonic cleaning device and optimizing the electrical performance of the ultrasonic cleaning device.

[0039] Furthermore, such as Figure 2 , 6As shown in Figure 8, the rotating joint 3 includes a first hinge portion 32 disposed on the flip cover 2 and a second hinge portion 33 disposed on the top of the outer shell 1. The first hinge portion 32 is located outside the second hinge portion 33 and is rotatably connected to the second hinge portion 33. The first wiring channel 31 includes a third through hole 311 disposed between the first hinge portion 32 and the second hinge portion 33. The first hinge portion 32 includes a first bearing seat 321 disposed on the upper cover pivot plate 23 and a second bearing seat 322 disposed on the upper cover seat 24 and corresponding to the first bearing seat 321. A hinge hole 323 communicating with the second receiving cavity 21 is formed between the first bearing seat 321 and the second bearing seat 322, and a reversing wall 324 opposite to the third through hole 311. The second hinge portion 33 is rotatably connected in the hinge hole 323, and the reversing wall 324 is spaced apart from the hinge hole 323. In this embodiment, the... The second hinge portion 33 is located on the top of the upper shell 11 and corresponds to the first hinge portion 32. The second hinge portion 33 is configured as a hinge shaft extending outward. The third wire hole 311 is located inside the hinge shaft and communicates with the first receiving cavity 10 and the second receiving cavity 21. During assembly, the hinge shaft is hinged in the hinge hole 323 between the first shaft seat 321 and the second shaft seat 322. By setting the first wiring channel 31 in the hinge shaft, the rotational connection between the flip cover 2 and the outer shell 1 and the internal wiring of the ultrasonic cleaning device can be ensured at the same time, avoiding the exposure of the wire S3, which helps to reduce the safety risk of the ultrasonic cleaning device. The wire S3 passes through the third wire hole 311 and is turned from the third wire hole 311 to the second wire hole 42 by the reversing wall 324, so as to pass through the second wire hole 42 and be electrically connected to the second circuit board S2.

[0040] In other alternative embodiments, such as Figure 8 As shown, the end of the second hinge portion 33 extends toward the second receiving cavity 21 relative to the first bearing 321 and the second bearing 322, so as to reduce the contact area between the wire S3 and the upper cover rotating plate 23 and the upper cover seat 24, thereby reducing the area of ​​wear on the wire S3 and extending the service life of the wire S3.

[0041] To reduce the assembly difficulty of the flip cover 2, in some alternative embodiments, the upper cover pivot plate 23 and the upper cover 22 can be connected by means of interlocking, snap-fitting, plugging, threaded connection, etc., so that the connection between the upper cover pivot plate 23 and the upper cover 22 is smooth and improves the appearance of the ultrasonic cleaning device; the upper cover 22 and the upper cover seat 24 can be connected by means of snap-fitting, plugging, threaded connection, etc., which helps to enhance the overall connection stability of the flip cover 2.

[0042] To further enhance the routing and positioning of conductor S3, in some alternative embodiments, such as Figure 10 As shown, the upper cover 24 also includes an assembly structure located between the first hinge portion 32 and the mounting cylinder 241. This assembly structure includes a wiring gap 242 communicating with the second receiving cavity 21, and second limiting portions 243 located on both sides of the wiring gap 242. The wiring gap 242 is located between the third through hole 311 and the second through hole 42. In this embodiment, the mounting cylinder 241 divides the second receiving cavity 21 into a first cavity 211 and a second cavity 212. The assembly structure is provided within this assembly structure. The assembly structure is located within the second cavity 212 and outside the mounting cylinder 241. It includes, but is not limited to, assembly columns and reinforcing ribs for connecting the upper cover pivot plate 23 and the upper cover seat 24. This embodiment does not impose specific limitations. Optionally, the assembly structure includes a first assembly part and a second assembly part disposed opposite each other within the second cavity 212. The wiring gap 242 is located between the first assembly part and the second assembly part, and the minimum width of the wiring gap 242 (i.e., the minimum distance between the first assembly part and the second assembly part) is equal to or greater than the diameter of the wire S3. Figure 10 As shown, the outlet of the first wiring channel 31, the wiring gap 242, and the second wire hole 42 are roughly on the same straight line, or the wiring gap 242 and the second wire hole 42 are slightly offset to the left relative to the outlet of the first wiring channel 31, so as to reduce the wiring distance of the wire S3 and reduce the bending degree of the wire S3, thereby helping to reduce the production cost and optimize the electrical performance of the ultrasonic cleaning device. In addition, the wiring gap 242 further positions the wire S3, making the assembly of the wire S3 in the second receiving cavity 21 more regular and simple, which is conducive to optimizing the wiring layout of the ultrasonic cleaning device.

The displacement of the sealing member 8 is restricted by the third limiting part 62 and the fourth limiting part 113, thereby improving the connection stability of the sealing member 8 and ensuring the connection sealing between the upper shell 11, the sealing member 8 and the mounting bracket 6.

[0047] To further improve the connection stability of the sealing member 8, in some alternative embodiments, such as Figure 6 and Figure 11 As shown, the outer side of the sealing member 8 is also provided with a protrusion 82 that abuts against the outer shell 1 and / or the mounting bracket 6; in this embodiment, the top and / or bottom of the sealing member 8 are provided with at least one protrusion 82, and the protrusion 82 is integrally formed with the sealing member 8. Optionally, the sealing member 8 is made of flexible materials such as rubber and silicone to achieve shock absorption. The protrusion 82 abuts against the mounting step 112 and / or the mounting bracket 6 to close the assembly gap between the upper shell 11 and the sealing member 8, and between the mounting bracket 6 and the sealing member 8. Combined with the elastic pre-tightening force of the sealing member 8 itself, the sealing connection between the upper shell 11, the sealing member 8 and the mounting bracket 6 is further strengthened, thereby further improving the connection stability and sealing performance of the sealing member 8.

[0048] Example 3:

[0049] Based on the ultrasonic cleaning apparatus of Embodiment 1 and / or Embodiment 2 above, in order to further improve the aesthetics of the ultrasonic cleaning apparatus, Embodiment 3 has the following implementation method, such as... Figure 4 and Figure 11As shown, a through hole 25 communicating with the first receiving cavity 10 and the second receiving cavity 21 is provided between the upper cover pivot plate 23 and the upper cover seat 24, and a sealing gasket 251 is located in the through hole 25. The through hole 25 corresponds to the outer side of the mounting cylinder 241. The sealing gasket 251 has a decorative gap 2511 communicating with the through hole 25 and the first receiving cavity 10. In this embodiment, the through hole 25 communicates with the inner cavity of the first receiving cavity 10 and the inner cavity of the cleaning inner tank 5. The sealing gasket 251 can be fixed on the upper cover seat 24 by means of bonding, threaded connection, snap-fit, etc. and is located in the through hole 25. The decorative gap 2511 communicates with the through hole 25 and the inner cavity of the cleaning inner tank 5. In some ultrasonic cleaning devices with heating function, the cleaning liquid in the cleaning inner tank 5 is heated and generates steam. In actual application, the steam can be discharged to the outside of the ultrasonic cleaning device through the decorative gap 2511 to ensure the internal pressure balance of the ultrasonic cleaning device, thereby protecting the ultrasonic cleaning device.

[0050] In other alternative embodiments, such as Figure 11 As shown, the upper cover pivot plate 23 has an assembly cylinder 231 extending downward from its top. The through hole 25 is located inside the assembly cylinder 231 and extends to the upper cover seat 24, communicating with the first receiving cavity 10. An installation space is formed between the upper cover pivot plate 23 and the upper cover seat 24, communicating with the through hole 25 and the second receiving cavity 21. The sealing gasket 251 is located in the installation space and is clamped and fixed by the assembly cylinder 231 and the bottom of the upper cover seat 24 to achieve a tight connection between the sealing gasket 251 and the flip cover 2. Further optionally, the sealing gasket 251 can be installed on the assembly cylinder 231 and the upper cover seat by means of adhesive, threaded connection, snap-fit, etc. Between 24; in addition, since the second receiving cavity 21 is located between the upper cover pivot plate 23 and the upper cover seat 24, and the second receiving cavity 21 is divided by the mounting cylinder 241 to form a first cavity 211 and a second cavity 212, the first cavity 211 is located inside the mounting cylinder 241 to accommodate the operation panel module, and the second cavity 212 is located outside the mounting cylinder 241 to accommodate the assembly structure. The through hole 25 corresponds to the outside of the mounting cylinder 241. The assembly gap and the through hole 25 are isolated outside the first cavity 211 by the assembly cylinder 231 to prevent steam from entering the first cavity 211 when it is discharged, which would cause the operation panel module to be easily flooded, thereby further protecting the operation panel module.

[0051] In other alternative embodiments, such as Figure 4 and Figure 11As shown, there are several sealing gaskets 251, and the through holes 25 are correspondingly arranged with the sealing gaskets 251; for example, there are two sealing gaskets 251, and the two sealing gaskets 251 are symmetrically arranged on both sides of the opening of the first cavity 211, that is, the two sealing gaskets 251 are symmetrically arranged on both sides of the operation panel module, which helps to improve the aesthetics of the ultrasonic cleaning device, optimize the user experience, and thus enhance the market competitiveness of the ultrasonic cleaning device.

[0052] In some alternative embodiments, a plurality of decorative gaps 2511 may be provided in the sealing gasket 251. Each decorative gap 2511 may be arranged in a row or staggered in the sealing gasket 251. The shape of the decorative gap 2511 may be a regular shape such as a strip, a circle, or a rectangle, or an irregular shape, to further enhance the aesthetics of the ultrasonic cleaning device. It should be noted that this embodiment does not specifically limit the shape and number of the decorative gaps 2511.

[0053] The above examples are merely illustrative of the technical content of this utility model to facilitate reader understanding, but do not imply that the implementation of this utility model is limited to these embodiments. Any technical extensions or re-creations made based on this utility model are protected by this utility model. The scope of protection of this utility model is defined by the claims.
